In the past few days, Xie Lunhua, the general manager of Foshan Langshi Lighting Co., Ltd., has been particularly busy. When I heard about the author, he squeezed time from his busy schedule. He just sat down, had not had time to talk a few words, and two other guests came to the door - they are the commissioner of Zhejiang Myers Lighting Co., Ltd., responsible for the promotion of LED lighting modules.
LED commercial lighting
"In fact, I have been considering the development of LED commercial lighting since 2004. After years of continuous exploration and research and development, I have achieved certain results. Compared with the classic high-power ceiling light, we have completely replaced the halogen lamp. The stage..." Xie always pointed to the products in the Langshi showroom, proudly said, "This year, we will increase investment in LED commercial lighting."
In 2009, the LED industry was fired, and there were many people like Xie Lunhua who drove into LED commercial lighting. However, due to its high price, LED commercial lighting has low recognition and accessibility in the market, and gradually formed a " The embarrassing situation of getting hot and cold.
LED commercial lighting products have obvious advantages
LED commercial lighting refers to lamps that use LEDs as a light source and can be used in commercial places while reflecting the characteristics of LED light sources, and can meet the lighting requirements of commercial places. It is generally suitable for use in stores where there are special requirements for energy saving and lighting. According to the scope of use, LED commercial lighting can be divided into LED key lighting and LED basic lighting, among which LED spotlights and LED ceiling lights are key lighting; LED factory miner's lamps, LED floodlights, etc. are basic lighting.
From a technical perspective, LEDs have significant advantages in commercial lighting applications, including energy savings, long life, instant start, and high color rendering. Traditional lamps used in commercial lighting include incandescent lamps, tungsten halogen lamps, fluorescent lamps, energy-saving lamps, and metal halide lamps. Undertake LED light source environmental protection, long life and other characteristics, LED lamps can be a good substitute for incandescent lamps, tungsten halogen lamps, energy saving ratio of up to 90%, life is 50 times that of these traditional lamps.
"Compared with traditional commercial lighting, LED commercial lighting has five advantages: 1, energy saving, LED commercial lighting is generally only 1 to 10W, in the case of similar brightness, power consumption is not much; 2, environmental protection, LED is a recyclable light source, Energy-saving lamps, halogen lamps, etc. all contain metal elements that pollute the environment (such as mercury), recycling becomes a big problem; 3, safety, LED light source is not high; 4, long life, theoretically, LED light decay can be reduced to 70% The nominal life of 100,000 hours, reducing the frequency of replacement and other maintenance work; 5, good light efficiency, color changes, 1W LED lamps can generally reach 90-100 lumens, equivalent to 5-6 times the general light source Asked about the difference between LED commercial lighting and traditional commercial lighting, Zou Yong, manager of the Huayi Group's Aokes lighting business unit, talked about it.
The heat dissipation problem is difficult to solve, and the LED supporting design is missing. Although the LED commercial lighting has obvious advantages from the technical point of view, the production of LED commercial lighting products is still in its infancy.
“Most enterprises just replace traditional commercial lighting products with LED light sources. Few companies specialize in designing LED light sources. After a new light source is generated, it should fully consider its heat dissipation, life and other factors in the reflector. The design of the use, lighting modeling and other aspects." Raymond Lighting Sales Director Ding Jianbo pointed out the current drawbacks of LED commercial lighting production.
Zhang Shengqiu, the general manager of Jin Jazz Lighting, also feels the same. He believes that “At present, LEDs lack industry standards, and good cars need good driver matching. In this regard, LED commercial lighting is too risky, not just a light source. simple". Therefore, Mr. Zhang led the Golden Jazz lighting team, increased research and development efforts, and has been exploring the LED commercial products, with the intention of developing and producing integrated LED commercial products.
For the design and development of LED commercial products, there are many factors that lighting companies should fully consider. Problems such as heat dissipation, brightness, illumination, glare, and color rendering need to be solved one by one. If the glare problem is solved from an optical point of view, it will cause insufficient illumination. Because the LED light source itself does not dissipate heat through the air like the energy-saving lamp and the halogen lamp, but needs to dissipate heat through a certain conductor, the design of the material is different from the traditional commercial product. At present, LED commercial lighting generally uses aluminum conductors and other conductors for heat dissipation. However, for high-power LED lamps, the heat dissipation part will be more difficult. In addition, LEDs have higher requirements for electronic components and require excellent component quality to support their strong life.
"Because of the high efficiency of LED commercial light source, high heat dissipation requirements, directionality of illumination angle, etc., the heat dissipation and light distribution characteristics of the lamps should be fully considered in the design of the lamps," said Xie Lunhua, general manager of Langshi Lighting.
The core technology is difficult to break through, and the cost is high. Compared with traditional commercial lighting, LED commercial photos have “two highsâ€. First, the product price is high, and second, the technical content is high. The core technology of LED commercial lighting is mainly its light source - LED technology, its core is LED chip technology. The core technology of LED chips is mainly in the hands of a few international big companies, and LED chip technology has a term protection on patents. Lighting companies have to add a lot of patent costs in the production of products, resulting in enterprises. The production cost is high. In addition, the domestic packaging technology is not mature, resulting in the quality of LED commercial lighting products, the low-end products are flooding the market. "LED commercial lighting costs are higher, generally 8-10 times higher, such as 3? 1W products, in The price of the ancient town is generally 8 yuan, and the cost of Damei is more than 50 yuan. And the light source and the light fixture are two different things, the light source is the core part. If the parts are purchased, the price is not much different, almost 5 yuan. 3? 3W LED products, its brightness is equivalent to 12V50W halogen lamps, spotlights, but the cost of the former is 58 yuan, the latter is 12 yuan, the difference is 46 yuan. For example, a row of ceiling lights 1 square meter An 2 lamp, a lobby with a minimum of 5,000 square meters, for example, 46 ??? 2 ??? 5000 = 460,000 yuan, the cost is too high." General Manager of Nanhai District, Foshan City, Damei Lighting Co., Ltd. Xiao Chisheng carefully counted the cost account. He pointed out that at present, LED commercial lighting is difficult to fully promote in the market, and high prices are its fatal cause.
Coincidentally, Zou Yongpan, manager of the Huayi Group's lighting business unit, also pointed out that the downlight is generally divided into three parts: the outer casing, the light source and the electric. The cost of traditional lighting is about 60 yuan, and the LED lighting is 200. Yuan.†It can be seen that LED commercial lighting costs are 3-4 times higher than traditional commercial lighting.
When the LED business photo is taken right?? Xie Lunhua, general manager of Foshan Langshi Lighting Co., Ltd.
The birth of LED commercial lighting conforms to the trend of global green energy-saving lighting. At present, it mainly replaces light-emitting sources such as high-pressure sodium lamps, halogen lamps, and the like, and lamps using these light sources. It can become the focus of current business, in addition to its very broad market prospects, and because it is a green lighting product, it can effectively reduce the harm to the environment. This is any socially responsible entrepreneur and enterprise. Can not be avoided, and should be vigorously developed and advocated.
In the next 5-10 years, with the dramatic improvement of LED light efficiency and ease of use, it must launch a new revolution in commercial lighting in the field of commercial lighting.
At present, although LED commercial lighting costs are high, the audience accepts limited, but only seize the first opportunity, in order to win the city often. This is like a queue, first-come-first, first-in-first to establish the status of the rivers and lakes, and then enter, it is inevitable to be behind.
LED business photos should not be too hasty?? Zhang Shengqi, general manager of Foshan Golden Jazz Lighting Co., Ltd.
In 2009, LED seems to be very hot, and it has also been used in LED commercial lighting. In fact, it is "the thunder is loud, the rain is oblique, and there are still many problems that have not been solved:
1. Lack of industry standards, lack of strict standards regarding lumens, wattage, size, etc. of products;
2, the price is expensive, generally 30% -50% expensive;
3. In theory, it is energy-saving and environmentally friendly, with long life and low efficiency. However, if the actual service life can reach so much, it will take time to verify.
At present, LED commercial lighting will not completely replace traditional commercial lighting, and will not be replaced in 10 years - can be replaced in auxiliary lighting, but can not be replaced in the main lighting. Because of the main lighting, you need to achieve a certain amount of lumens, illumination, the cost will be quite high, so the price will be multiplied. 
To assure the quality, we will do 100% inspection for raw material, production procedure, packing before shipment,
so we do have the confidence to supply customers with high-quality and high-efficiency products.
