Summary: At present, there are three chaos in the energy-saving lamp market: one chaos is the chaos of product technology quality, the second chaos is the chaos of sales price, and the chaos is the chaos of manufacturers. The technical quality and technical service of the products are mixed and the difference is very different. It has made consumers unpredictable, and it is difficult to scientifically and correctly purchase energy-saving lamps with excellent technical quality and technical services. The author of this article is based on the technology research and development practice of energy-saving lamps for many years, and the accumulated information on the energy-saving lamp market. Propose some technical standards and judgment methods that can be visually judged on the spot when purchasing energy-saving lamps. For consumers' reference.

First, when choosing energy-saving lamps, the main points are as follows:
(1) Light efficiency and effective pupil lumens :
1. Energy-saving lighting effect: It is a physical quantity that characterizes energy-saving lamps and converts electrical energy into high-efficiency light energy. The unit is: lumens / watt (Lm / W). According to the current technical level of energy-saving lamps produced in China, the energy-saving lamps with good quality have a light effect of 40 - 60 lumens per watt (Lm/W). The actual luminous efficacy of energy-saving lamps is directly related to the technical quality of fluorescent tubes and electronic ballasts, and the reasonable degree of matching between the two.
2, energy-saving lamps effective pupil lumens (also known as effective visual light effect): is a physical quantity that characterizes the amount of visible light in the luminous flux produced by energy-saving lamps that can be visually perceived by human eyes. Effective pupil lumens (also known as effective visual efficacy) are purely digital physical quantities that indicate the validity of the source's luminous flux. The mathematical expression is:

Effective pupil lumens =

The actual effective pupil dimming level of the energy-saving lamp is directly related to the technical quality of the fluorescent tube and the electronic ballast itself. Tri-color fluorescent tubes, and AC-DC-AC conversion frequency, high-frequency electronic ballasts above 40Khz, matched high-frequency energy-saving lamps. The effective pupil lumen (also known as effective visual light effect) is high, and the actual brightness of the energy-saving lamp is high.
If the energy-saving lamp can achieve light efficiency and effective pupil lumen, the two technical parameters are relatively high. The technical quality of energy-saving lamps is excellent, and the power saving rate is high.
The physical meaning of effective pupil lumen (also known as effective visual light effect) can be found in the article "Basic Concepts of Green Light Sources".
3, in order to be able to visually judge the level of energy-saving lighting, and the effective pupil level, you can use the "power-brightness" comparison method to compare:
(1), comparison method: choose a 25OW high-pressure mercury lamp, a light-saving lamp. Light up at the same time, observe the brightness of the two sources, and see how much the energy-saving lamp can be brighter than the high-pressure mercury lamp. Afterwards, the mercury lamp and the energy-saving lamp were turned off in turn, and the illumination of the surrounding space and the ground was observed when the mercury lamp and the energy-saving lamp were lit respectively.
(2) Two physical quantities that need to be correctly understood:
One is brightness, which refers to the brightness of the light that the person feels when looking at the light source. The brightness is determined by the color temperature of the light source and the luminous flux of the light source. The luminous flux of the light source is a decisive factor. The light source has a large luminous flux and a high brightness.
The second is illuminance, which refers to the amount of light flux that the light source illuminates into the surrounding space and the ground. The light source illuminates the surrounding space and the ground with more luminous flux, and the illuminance is high.
The third is the brightness and illuminance of the light source, the same points and different points of the two physical quantities. The same point is that the physical quantities that affect the brightness of the light source and the illuminance are common, namely: luminous flux. The difference is: the luminous flux that affects the brightness of the light source, refers to the amount of light flux radiated from the surface of the light source; the luminous flux that affects the illumination of the light source refers to the amount of light flux that the light source radiates onto the illuminated surface (such as the wall, the ground, and the work surface). The positions of the two are different, the quantity relationship is different, and the external influence factors are also different. In actual production and living lighting design and measurement, the value of the physical quantity of illuminance is mainly evaluated.
(3) Contents that need special explanation:
The brightness of the light source is sometimes greatly affected by the color temperature. In a light source with the same luminous flux, a light source with a high color temperature produces a high-visual visual sense. This kind of "high-brightness" light source is not higher than other light sources, and the light effect is not higher than other light sources, just a glare "false light".
(4), power - brightness comparison method, comparative physical quantity and standard:
A. Comparative physical quantity: power - brightness comparison method, the physical quantity to be compared. By comparison: the amount of light that a different light source radiates onto the illuminated surface (such as the wall, the ground, the work surface), that is, the illuminance value on the illuminated surface; the power consumption of the two different light sources. In turn, the effective visual effects of different light sources are compared.
Effective visual light effect is the main physical quantity for comparing different light sources in actual production and living lighting design and measurement. The mathematical expression for effective visual efficacy is:

Effective visual light effect = Or effective visual light effect =

B. Comparison standard: According to the current technical level of energy-saving lamps produced in China, the light efficiency of energy-saving lamps with good quality should be 40-60 lumens/watt (Lm/W). Effective visual efficacy should be 80-100 lumens per watt (Lm/W).
Instead of a high-pressure mercury lamp, the brightness is slightly increased or equivalent after the replacement is guaranteed. 1W energy-saving lamp can replace 2W high-pressure mercury lamp, the replacement ratio is 1:2. If the substitution ratio is <1:2, the energy efficiency of the energy-saving lamp is too low, which is an inferior product.
4, Qingdao Huabeier microelectronics studio high-frequency light source business unit, is specialized in three high-frequency high-frequency high-efficiency industrial special energy-saving lamps (referred to as high-frequency energy-saving lamps), high-frequency electronic ballast production of high-tech enterprises.
It adopts rare earth trichromatic high luminous efficiency fluorescent tube; high frequency and high lumen coefficient electronic ballast. Production and matching commissioning are carried out in strict accordance with the process technology of “independent optimization, best matching”.
Qingdao Huabeier high-frequency and high-efficiency energy-saving lamps have advanced technical performance and excellent technical quality. High luminous efficiency, effective pupillary lumens (effective visual efficacy) up to 120 watts (Lm) per watt (W). When lit, the tricolor fluorescent tube is bright and translucent, with a visual sense similar to glass melting. You can't see the outline of the fluorescent tube and only see an overall bright light column.
With Qingdao Huabeier high-frequency high-efficiency energy-saving lamps, instead of high-pressure mercury lamps, 1W high-frequency high-efficiency energy-saving lamps can replace 5W high-pressure mercury lamps; the replacement ratio is 1:5. The power saving rate is over 80%.
With Qingdao Huabeier high-frequency high-efficiency energy-saving lamps, instead of T 8 straight tube fluorescent lamps, 1W high-frequency high-efficiency energy-saving lamps can replace 3. 5WT8 straight tube fluorescent lamp; the replacement ratio is 1:3. 5, saving more than 70%.
5. It should be specially stated that the energy-saving lamps being sold in the market, the luminous efficacy and the effective pupillary lumens are not all relatively high. The effective pupil lumens of most energy-saving lamps are only within 40 lumens (Lm) to 60 lumens (Lm) per watt (W) of electrical power.
The intuitive identification method is: The inferior lamp is not a pure three-primary fluorescent tube. When lit, the fluorescent tube light color is blue-gray, and the gray-light blur is low. The outline of the fluorescent tube is clearly seen.
Energy-saving lamps that are being sold in the market, instead of high-pressure mercury lamps, 1W energy-saving lamps, can replace up to 2.5W high-pressure mercury lamps; the power saving rate is only below 40%.
(2) Failure rate and life: It is a physical quantity that characterizes energy-saving lamps and technical quality. The two physical quantities, failure rate and lifetime, are both related and independent. In the lighting industry and users, the two are often confused or equivalent due to lack of scientific and correct understanding.
1. Life is a physical quantity that characterizes energy-saving lamps and can be reliably ignited and ignited in normal use space environment and power grid environment. Usually measured in hours (h). The end of life of energy-saving lamps is due to the exhaustion of the effectiveness of electronic components (such as electrolytic capacitors) that constitute energy-saving lamps, or the exhaustion of useful substances (such as phosphors) of fluorescent tubes. At present, according to the technical quality level of fluorescent tubes in China, and the technical quality level of electronic components. The energy-saving lamp whole lamp, Qihui ignition life, should be 6000 hours - 8000 hours.
The life of the energy-saving lamp is the usefulness of the electronic components and fluorescent tubes, and the effectiveness is exhausted. Technical factors subject to four aspects (ie: independent optimization, best match):
First, fluorescent tubes: the technical quality of the phosphors, electronic powders, and luminescent gases used in the tubes, and the level of production technology.
The second is electronic components: technical parameters consistency, reliability level and other technical qualities. And on the electronic components, screening aging production technology level.
The third is the advanced performance of electronic ballast technology: technical factors such as technical quality. Such as AC-DC-AC (AC-DC-AC) conversion frequency. Low is bad, high is good.
The fourth is the reasonable matching of technical parameters between the fluorescent tube and the electronic ballast.
2. The failure rate is a characterization of energy-saving lamps. During the life of Qihui ignition, due to the technical factors such as the electronic components, devices, fluorescent lamp technical quality and overall lamp technical performance of energy-saving lamps, a physical quantity of energy-saving lamps cannot be ignited. . The failure rate is usually described by the percentage (%). At this stage, the failure rate of energy-saving lamps, the difference between products and products, is relatively large.
The failure rate of energy-saving lamps is subject to the technical factors of the following three aspects.
First, the energy-saving lamp production enterprise, the technical ability of scientific research and development;
Second, energy-saving lamp production enterprises, production technology level;
The third is the technical quality of electronic components, devices and fluorescent tubes used by energy-saving lamps manufacturers.
3. Method for identifying the failure rate and life of energy-saving lamps. To truly identify the failure rate and life of energy-saving lamps, it is not possible to do a test in the laboratory. Rather, it is necessary to pass the actual application of the space environment and the grid environment to verify the quality of the energy-saving lamp failure rate and life.
In the actual purchase, the most direct identification method:
The first is to identify the wide voltage withstand of energy-saving lamps. The energy-saving lamp is connected to the auto-coupler, and the energy-saving lamps are respectively placed in three voltage states of 180 V, 220 V, and 260 V, and each is continuously ignited for 24 hours. Take a look at whether the energy-saving lamp Qihui ignition is stable and reliable.
The second is to identify the ability of energy-saving lamps to adapt to the application environment. The energy-saving lamps are placed in the application space of -15 degrees - 10 degrees, respectively, and are continuously ignited for 24 hours in three voltage states of 180 V, 220 V, and 260 V. Take a look at whether the energy-saving lamp Qihui ignition is stable and reliable.
The third is to understand the case of energy-saving applications, and visit to understand the application. Pay particular attention to the practical examples of applications where the voltage drop is severe and the harmonics are severe; such as high-power AC, DC resistance welder production workshop, high-current AC welder production workshop. Are there practical examples of applications in high temperature, high humidity environments, such as steelmaking foundry, rubber molding workshops, and oil extraction plants.
4, Qingdao Huabeier Microelectronics Studio High Frequency Light Source Division is a high-tech enterprise specializing in the production of high-frequency and high-efficiency industrial special energy-saving lamps and high-frequency electronic ballasts.
The three-color high-efficiency fluorescent tube used by the company is commissioned by Taiwanese professional fluorescent tube manufacturer.

(For the technical meaning of "fuzzy adaptive control", see the article "Technical characteristics and accelerated life aging test report" in this paper.
The three-color high-frequency high-efficiency industrial special energy-saving lamp whole lamp is produced, and the three-primary high-efficiency fluorescent lamp and the high-frequency electronic ballast are used. Production and matching commissioning are carried out in strict accordance with the process technology of “independent optimization, best matching”.
Therefore, Qingdao Huabeier three-color high-frequency high-efficiency industrial special energy-saving lamps, and high-frequency electronic ballasts, advanced technical performance, reasonable technical parameters, and excellent technical quality.
l U-tube and spiral tube energy-saving lamp whole lamp, Qihui ignition life:
Engineering version 15,000 hours;
The technical version is 20,000 hours;
l T 5 , T 6 straight tube type energy-saving lamp whole lamp, Qihui ignition life:
Engineering version 20,000 hours;
l High frequency electronic ballast, Qihui ignition life:
40,000 hours.
l High frequency energy saving lamp and high frequency electronic ballast,
The failure rate is within 1.5% - 2%.
5. What needs to be specially stated is: most of the energy-saving lamps being sold in the market. Its ignition life is not long, the vast majority in 5000 hours - 6000 hours. Qihui ignition failure rate is high, generally around 20% - 30%. More inferior energy-saving lamp manufacturers do not have the ability to develop scientific research and technology. Take the method of copying PCB boards, and use low-quality electronic components, devices, and fluorescent tubes for production. The energy-saving lamp is full of lights, and the ignition life of Qihui is within 5,000 hours. The ignition failure rate of Qihui is also astonishing, up to 50% - 150%. There are even "week lights, half moon lights".
More inferior energy-saving lamp manufacturers, in order to extend the life of energy-saving lamps. It is not the use of advanced technology to optimize the technical performance of electronic ballasts. Rather, it is erroneous to take a drastic reduction in brightness and to extend the life of the energy-saving lamp. This kind of energy-saving lamp that consumes only electric energy and has low brightness is really long life and what is the positive significance?
(3), color rendering index and color rendering performance:
1. Color rendering performance: It is a physical quantity that characterizes energy-saving lamps and displays the original color of the surface of the object. The performance of energy-saving lamps is determined by the technical quality of fluorescent tubes. Fluorescent tubes such as rare earth trichromatic phosphors, fluorescent tubes have high color rendering properties; if halogen or hybrid phosphors are used, fluorescent tubes have low color rendering properties. Fluorescent tubes with high color rendering performance, color objects are not subject to color deviation, and color objects are bright and true. Fluorescent tubes with low color rendering performance, color deviation caused by viewing colored objects, and the color of colored objects is gray and fuzzy.
2, color rendering index: in order to be able to visually describe, the energy-saving lamp color rendering performance, introduce the concept of color rendering index R value. The solar color rendering index R=100 is used as the standard. The higher the actual color rendering index R of the energy-saving lamp, the closer the color rendering performance of the energy-saving lamp is to the sunlight, and the better the color rendering performance of the energy-saving lamp. Watch the original color of the surface of the colored object, the more realistic and natural. According to the current production level of fluorescent tubes, the color rendering index R value of energy-saving lamps should be above 40-80.
3, color rendering performance identification method: in the actual purchase of energy-saving lamps, identify the energy-saving lamp color rendering performance of the intuitive method.
One is to choose a piece of colored fabric of about 0.5 square meters, first look at the color under the sun, remember the effect under the sun. Then put it under the energy-saving lamp to watch its color, remember the effect under the energy-saving lamp. Compare the degree of color difference in color fabrics under sunlight and under energy-saving lamps. The smaller the difference, the higher the color rendering performance of the energy saving lamp.
The second is to compare the colored fabrics under two energy-saving lamps. The color fabrics are bright, clear and real, and the energy-saving lamps have high color rendering performance.
In the actual purchase, energy-saving lamps with high color rendering performance should be selected.
4. Qingdao Huabeier Microelectronics Studio High Frequency Light Source Division is a high-tech enterprise specializing in the production of high-frequency and high-efficiency industrial special energy-saving lamps and high-frequency electronic ballasts.
Rare earth trichromatic fluorescent tube, commissioned by Taiwanese professional fluorescent tube manufacturer. According to the designated brand manufacturers, imported from Japan, rare earth trichromatic phosphors and high quality electronic powder. The use of solid amalgam, according to the technical parameters of our design, and the specified process technology customized production.
Standard color rendering fluorescent tube with a color rendering index R value greater than 85. High color rendering fluorescent tubes, the color rendering index R value has reached 95. Close to the color rendering performance of sunlight (R value = 100). Watch the color of the surface of colored objects, vivid and natural.
5, need to specify: the energy-saving lamps that are being sold in the market, the color rendering performance is not always high. For most energy-saving lamps, the color rendering performance is still relatively low. Its color rendering index R value is only R = 30 - 60. Only some of the better energy-saving lamps have a color rendering index of 80.
(four), color temperature:
Energy-saving lamp color temperature, also known as the relevant color temperature. It is a physical quantity that characterizes the energy saving lamp, the color of light. It is related to the setting of technical parameters of fluorescent tubes, and is divided into low color temperature, medium color temperature and high color temperature. The color temperature is high and low, which does not represent energy-saving lamps, and the technical quality is good or bad.
Intuitive visual perception of color temperature:
Low color temperature (2700 K - 3500 K), containing more red and orange light, like the sun around 8 o'clock in the morning. Give people a warm, gentle beauty.
Medium color temperature (3500 K- 4500 K), the red, blue and other light colors are more balanced, just like after 8 o'clock in the morning, before ten o'clock in the sun. Gives a gentle, comfortable beauty.
High color temperature (5500 K- 7000 K), containing more blue light, like after 10 o'clock in the morning, before 2 pm. Give people a bright, clear beauty.
The choice of color temperature of energy-saving lamps: mainly based on the needs of energy-saving lamp application environment. For household and commercial lighting environments, low color temperature and medium color temperature are usually selected. For example, in industrial production workshops and square lighting environments, high color temperatures are usually chosen. Schools, military camps, office lighting environments, usually choose a high color temperature.
Recently, there has been a new scientific understanding of the choice of color temperature. Its light color concept is: return to nature, learn from the sun, and use the sun as the standard. In addition to the home bedroom, choose a low color temperature and a medium color temperature. In other lighting environments, high color temperatures are selected.
(5), stroboscopic and stroboscopic effects :
It is a physical quantity that characterizes energy-saving lamps, the depth of fluctuation of light, and the magnitude of the harmful effects (called stroboscopic effects) caused by fluctuations in light.
1. Strobe: refers to the depth of fluctuation of the luminous flux of the light source. The greater the fluctuation of the luminous flux, the more severe the stroboscopic. The depth of fluctuation of the luminous flux, usually expressed as a percentage. The depth of fluctuation of the luminous flux of the light source is directly related to the type of the light source and the technical performance of the light source. At present, widely used, magnetic ballast driven T 8 straight tube fluorescent lamp, high pressure mercury lamp, high pressure sodium lamp. The flux fluctuation depth is as high as 55 % - 65 %.
2, stroboscopic effect: refers to the fluctuation of the luminous flux of the light source, that is, the harmful effect of stroboscopic. The more severe the strobe of the light source, the greater the stroboscopic effect.
The performance of stroboscopic effects:
(1) Initiating a work-related accident: when the stroboscopic frequency of the light source is in integral multiple with the speed (rotation speed) of the moving (rotating) object. When the motion (rotation) state of a moving (rotating) object occurs, the static, reverse, motion (rotation) speed is slow, and the above three states, the repeated visual error, cause an industrial accident.
u For example, the sewing machine operator in the garment industry illusion that the needle moving up and down at high speed is in a static state, and the finger is inadvertently injured.
u For example, the machine tool operator in the machining industry, the illusion is reversed for a forward-rotating turning tool. The emergency reversing operation, damage to the workpiece, the tool, and even cause casualties.
u For example, in the machinery industry, crane operators, for the movement state of the crane and the hook, produce a false vision of slow moving speed and momentary rest. It is difficult to locate, causing operational errors and causing accidents.
u For example, in the machinery industry, the production operator's speed of the flywheel and pulley of the production equipment. Produce false visions such as slow rotation and reverse rotation. Lead to misuse and cause an accident.
(2), resulting in low production efficiency: stroboscopic effect will cause visual fatigue, migraine. In particular, the machinery industry uses high-pressure mercury (sodium) lamps, and light industry, food, printing, electronics, textiles and other industries, the use of T 8 straight tube (inductive) fluorescent lamps is particularly obvious. For example, plug-in operators on the assembly line are prone to migraine headaches due to visual fatigue and vertigo. It is difficult to locate and the production efficiency is low.
(3) Injuring the eyes of growing adolescents and forming myopia. After the 1980s in China, straight-tube (inductive) fluorescent lamps were widely used in homes, schools, and libraries. The growing primary and secondary school students suffered greatly, their visual acuity decreased significantly, and myopia increased significantly.
3. Mechanism of stroboscopic generation: The technical mechanism of stroboscopic generation by electric light source, both the factors of power supply, the factors of technical performance of electric light source, and the unreasonable factors of lighting design. And it is the result of a combination of many factors, the technical mechanism is more complicated. Due to space limitations, this article only provides a general technical analysis from the perspective of the performance of common electric light source technology.
( 1), electric light source power supply frequency is low: high pressure mercury lamp, high pressure sodium lamp, straight tube type (inductive) fluorescent lamp. At this stage, most of them are powered by a 50Hz power frequency sinusoidal alternating current directly to the illuminant of the electric light source. The stroboscopic frequency is 50 Hz *2 = 100 Hz, and it fluctuates sinusoidally.
(2), electric light source supply voltage fluctuations: China's current power frequency AC power supply, the instantaneous voltage value fluctuation range between 10% ~ 20%, greatly increased the frequency of 100Hz, sinusoidal fluctuations of the stroboscopic depth.
(3) The performance of the electric light source technology is backward: high-pressure mercury lamp, high-pressure sodium lamp, straight tube type (inductive) fluorescent lamp, although it is an electric light source for gas discharge and illumination. However, due to its start-up and ignition, inductive ballasts are used (the AC-DC-AC frequency conversion function is not available). Therefore, the discharge luminous power of the gas discharge illuminator must fluctuate sinusoidally with the frequency of the power supply.
(4) Eliminating the stroboscopic technical countermeasures of the light source: The fundamental technical countermeasure for eliminating the stroboscopic light source is to increase the driving electric power frequency of the illuminating body of the driving electric light source to make it reach 40KHz or more.
Relative to energy-saving lamps, the technical measure to eliminate stroboscopic and stroboscopic effects is to increase the frequency of electronic ballasts, AC-DC-AC (AC-DC-AC) conversion. When the electronic ballast, AC-DC-AC (AC-DC-AC) conversion frequency, reaches 40 thousand cycles (KHz) or more [CE certification specifies 40 thousand cycles (KHz)]. The stroboscopic depth of the energy-saving lamp can be limited to less than 5%. There are no more stroboscopic and stroboscopic effects.
The performance and mechanism of stroboscopic and stroboscopic effects. Xiang Xiang sees in this paper, "On the harmfulness of the stroboscopic effect of electric light source and improvement measures".
(5) Method for identifying the stroboscopic and stroboscopic effects of energy-saving lamps: The intuitive identification tool uses a stroboscopic dedicated detection gyro.
Identification methods and standards:
First, the identification method: select a plane, set one high pressure mercury lamp and one energy saving lamp. The high-pressure mercury lamp and the energy-saving lamp are respectively illuminated, and the dedicated detecting gyro is rotated on a plane. Observe the color change and pattern change of the pattern when the dedicated detection of the gyro turns.
The second is the identification criteria:
The dedicated detection gyro is first rotated under a high pressure mercury lamp. The dedicated detection gyro produces multiple halos of different colors, and each aura will exhibit a random change in the direction of rotation, rotation speed, and color as the rotation speed of the gyro changes.
Then, the dedicated detection gyro is placed under the energy-saving lamp to rotate. The dedicated detection gyro only produces a black and white aura, and the black and white aura, the rotation direction, the rotation speed, and the color do not change with the change of the rotation speed of the gyro.
Identification standard, dedicated detection of gyro, only produces a black and white phase of the energy-saving lamp, no stroboscopic and stroboscopic effects. Dedicated detection of the gyro, the generation of high-pressure mercury lamps with different colors of different auras, with stroboscopic and stroboscopic effects. In a variety of light sources or the same kind of light source, the richer the pattern change, the deeper the color color changes, the more severe the stroboscopic light source, the more serious the stroboscopic effect, and the more serious the hazard.
(6), Qingdao Huabeier Microelectronics Studio High Frequency Light Source Division is a high-tech enterprise specializing in the production of high-frequency and high-efficiency industrial special energy-saving lamps and high-frequency electronic ballasts.
The Huabel series produced by the company is a U-shaped tube and a spiral tube with three high-frequency and high-efficiency industrial special energy-saving lamps, and a T 5 straight tube type three-color high-efficiency energy-saving lamp. The matched electronic ballast, AC-DC-AC conversion frequency, is up to 4 5 KHz - 55 KHz or more. The stroboscopic depth is limited to less than 5%. There is no stroboscopic and stroboscopic effect hazard.
(7) Special explanation: The energy-saving lamps sold in the market, the conversion frequency of the electronic ballasts are not all above 40KHz. For most energy-saving lamps, the conversion frequency is only around 20KHz. Some are inferior energy-saving lamps, as low as 17 KHz. Still producing a stroboscopic depth of 2O-3O%, there is still a serious stroboscopic effect hazard.
When using the dedicated detection gyro detection, it produces a halo that is not purely black and white, but a halo that is slightly blurred and slightly orange-red. Randomly changes as the rotation speed of the gyro changes.
(6) Establish a scientific concept of high performance/price ratio:
It is not advisable to purchase energy-saving lamps and simply pursue low prices. Simply pursuing high-tech performance and high-tech quality should not be. The scientific concept of high performance/price ratio should be established according to the use objectives and requirements. That is to say, to meet the use, less money, more electricity, more money.
1. Satisfy the meaning of use:
First, to meet the operating table illuminance requirements: the operating table illuminance, all industries, all units have standard requirements, can refer to implementation.
The second is to meet the requirements of the production process for color rendering performance: the color rendering index R value should be higher than 80, especially in textiles, clothing, printing and dyeing, shopping malls and other occasions should pay attention.
The third is to meet the requirements of the stroboscopic effect at the production site: the stroboscopic depth should be less than 5%, no stroboscopic effect hazard, especially in clothing processing, machining workshops and other occasions should pay attention.
2. The meaning of performance:
First, energy-saving lighting effects and power saving rates. For example, instead of high-pressure mercury lamps, and the power ratio of T 8 straight tube fluorescent lamps. According to the current technical level of energy-saving lamps produced in China, high-quality mercury lamps are replaced by energy-saving lamps with better quality. After the replacement is guaranteed, the brightness is slightly increased or equivalent. 1W energy-saving lamp can replace 2W high-pressure mercury lamp, the replacement ratio is 1:2. If the substitution ratio is <1:2, the energy efficiency of the energy-saving lamp is too low, which is an inferior product. If the replacement ratio is >1:3 or more, it is an energy-saving lamp with excellent technical quality.
The second is the failure rate and life. According to the current technical level of energy-saving lamps produced in China, and the energy-saving lamps with good quality, the ignition life of Qihui should be more than 8,000 hours. The failure rate should be kept within 5% of the ignition life of Qihui. Energy-saving lamps with high failure rates are inferior products.
The third is to replace the lamp separately. The energy-saving lamp is composed of two parts: an electronic ballast and a fluorescent tube. The electronic ballast ignites the life of the ignition, which is greater than the ignition life of the fluorescent tube. In the subsequent replacement, if the fluorescent tube can be replaced separately, the subsequent low-cost replacement target can be achieved to keep the running cost low. For energy-saving lamps for factories, separate energy-saving lamps that can be replaced with fluorescent tubes alone should be selected.
The fourth is the technical service capability of the manufacturer or distributor. Technical service capabilities include: pre-sales technology, and tailor-made design and production according to user needs; on-site technical measurement in sales; after-sales quality assurance technical services. Technical service capabilities are based on the strength of scientific and technological research and development. Manufacturers and pure sellers who use PCB board production do not have technical service capabilities. Please consider carefully when purchasing energy-saving lamps.
3. The meaning of performance/price ratio;
The performance/price ratio of energy-saving lamps is a scientific method to identify the comprehensive economic performance of energy-saving lamps. Energy-saving lamps with high performance/price ratio can be excellent in technical quality. Special note: Low-cost energy-saving lamps are not equal to energy-saving lamps with high performance/price ratio. When actually purchasing energy-saving lamps, you can't just look at the price of energy-saving lamps, and you can't just look at the performance of energy-saving lamps. It is necessary to identify the performance/price ratio of energy-saving lamps, which is the scientific and correct method of purchase.
To identify the performance/price ratio of energy-saving lamps, the most direct and practical method in reality is:
First, according to the average unit turn time each day to calculate the savings of electricity per day and electricity.
The second is based on the cost of the purchase of light and electricity savings per day, calculate the number of days to recover the investment. If the number of investment days is small, the performance/price ratio of energy-saving lamps will be high.
Third, energy-saving lamps subsequent runs, inexpensive replacement. In order to realize the follow-up operation of the energy-saving lamps and the low replacement, the energy-saving lamps must be stable in operation and low in failure rate.
For detailed power saving and investment payback period calculation, please refer to the article “Power Saving Effect Calculation” in this document.

With Qingdao Huabeier high-frequency high-efficiency energy-saving lamps, instead of high-pressure mercury lamps, 1W high-frequency energy-saving lamps can replace 5W high-pressure mercury lamps; the replacement ratio is 1:5. The power saving rate is over 80%. If you turn on the lights for 10 hours every day, you can recover your investment within two months.
With Qingdao Huabeier high-frequency high-efficiency energy-saving lamps, instead of T 8 straight tube fluorescent lamps, 1W high-frequency energy-saving lamps can replace 3. 5WT8 straight tube fluorescent lamp; the replacement ratio is 1:3. 5, saving more than 70%. If you turn on the lights for 20 hours every day, you can recover your investment in two to three months.
Qingdao Huabeier high-frequency high-efficiency energy-saving lamps, its engineering version is a split-type industrial special series. After the end of the life of the fluorescent tube, the lamp can be replaced separately, and the subsequent operation cost is low. Ideal for factory floor lighting.
Qingdao Huabeier high-frequency high-efficiency energy-saving lamps are the most energy-saving lamps with the highest performance/price ratio at this stage.
(7) Correctly treat the brand and certification:
Brand and certification are external manifestations of the outstanding quality of energy-saving lamps. For the manufacturers of business management practices, the brand and certification of their products can be trusted.
However, special attention should be paid to such a commercial behavior: some energy-saving lamp manufacturers do not rely on improving product technical quality and technical services to open up the market. Instead, starting from the commercial interests, you can arbitrarily set a name, print a package, claim to be a well-known brand and obtain a number of certifications, and dump at a low price in the market. After a while, you can freely set a name, print a package, and then transfer to another area to dump at a low price in the market. Special attention should be paid to the manufacturers and products of this "packaging wheel rotation", beware of being fooled.
There are also a small number of producers, advertising is loud, and some certifications have been obtained. However, its products are not excellent because the advertising forensics and product production are two skins. Please pay attention to the identification.
(8) Scientific understanding of the meaning of the energy-saving lamp warranty for one year:
1 Scientific basis for one year warranty:
First, according to the technical quality level of fluorescent tubes in China and the technical quality level of electronic components. The energy-saving lamp whole lamp, Qihui ignition life, should be 6000 hours - 8000 hours or more.
The second is the time of year = 365 days x 24 hours / day = 8760 hours.
The above two points are the energy-saving lamp manufacturers, and promise to guarantee the scientific basis of one year warranty.
2. Scientific understanding of the concept of one year warranty:
The one-year warranty means that within one year after the sale of the energy-saving lamps, the energy-saving lamps will not be ignited due to the cause of the failure within the life span. The process of replacement is the responsibility of the manufacturer or distributor.
Here, we should pay special attention to the first point: the energy-saving lamp can't ignite, it is due to the failure of the energy-saving lamp, not the life of the energy-saving lamp.
Here we should pay special attention to the second point: since it is the cause of the failure, there should be an indicator of the failure rate. According to the technical quality level of fluorescent tubes in China, and the technical quality level of electronic components. The energy-saving lamp whole lamp, within the life span, the ignition failure rate should be around 5%. Qihui ignited the failure rate. If it is high, the technical quality of energy-saving lamps is too bad. Qihui ignited the failure rate. If it is as high as 50% or more, or as high as 100% or more, it is the life expectancy of the energy-saving lamp.
Therefore, when purchasing an energy-saving lamp, special attention should be paid to the identification, and the failure rate of the energy-saving lamp cannot be ignited. The reason why the energy-saving lamps can not be ignited is caused by the failure of the energy-saving lamps or due to the life of the energy-saving lamps.
3. Scientific understanding of the promise of one year warranty:
Manufacturers and distributors are committed to one year warranty and free replacement. This has been the consensus standard for the energy-saving lamp industry.
But there are two points that should be taken seriously:
一是 节能灯坏的数量多了，或者损坏频率高了，生产商和经销商是否能真正给予更换。
二是 即使生产商和经销商予以更换，但更换的节能灯数量多、次数多。对生产效率造成的不利影响，和较高的更换成本，使用者是否能承受得住？

二、怎样科学选择节能灯生产商：
1. 看一下生产商的节能灯，是否光效高、节电率高；故障率低、寿命长，是否具有先进的技术功能。
2. 看一下生产商的节能灯，有无出厂日期的确切标识。若没有，很难确定质量保证的起止时间，生产商质保的承诺也就很难履行。
3. 看一下生产商，是否为专业化生产商，有没有专业研发工程技术人员。
4. 看一下生产商，是否有向用户提供现场技术勘查，根据用户需求量身定制设计生产。以及在节能灯发生故障后，及时确定原因，并进行技术改进的技术实力。
5. 看一下生产商，有没有在外资企业，特殊行业的应用案例。并取得企业与行业的认同。
6. 看一下生产商，有没有在电源电压跌落严重、浪涌电流大、谐波干扰严重的供电场合，成功应用的案例，并取得企业的认同。
7. 看一下生产商，有没有在高温、高湿、密闭环境、烟尘污染严重、光线穿透力差等特殊生产场合，成功应用的案例，并取得企业的认同。
