A few days ago, when I saw 1500 sets of new LED energy-saving lamps and installed Tiananmen Tower as a contour light, Guo Xiaoyun, the chief engineer of Chongqing Yuanguang Electronic Technology Co., Ltd. and the State Council government subsidy, took a long sigh of relief.
On the eve of the Olympics, the Tiananmen Gate changed lights
Guo Xiaoyun said that based on the concept of the Green Olympics, the contour lights of the Tiananmen Gate Tower were also required to be replaced with new environmentally-friendly and energy-saving lamps on the eve of the Olympic Games. Chongqing Yuanguang Electronic Technology Co., Ltd. also received the task of developing new energy-saving light sources. At the same time, not only Chongqing and domestic enterprises, but also many big names in the international lighting industry are involved in the competition. The competition is fierce.
At present, many energy-saving lamps in the world have a lifespan of only 8,000 hours, and the luminous efficiency is only about 50%. Tiananmen Contour Light The basic requirement for this lamp replacement is that it will not be replaced for at least 3 years, and it is required to be energy efficient. In addition, the normal voltage is generally 220 volts, and the voltage of the Tiananmen contour light is between 240 and 260 volts, so the power supply requirements are very demanding. Guo Xiaoyun said that after half a year of hard work, the new LED light source bulb DHLEDQ60-3 was finally developed.
Power meter size, with a magnifying glass to weld
Guo Xiaoyun revealed that the new LED light source developed, in addition to the chip is the technology of the US GYEE company, the rest are self-designed.
Don't underestimate this small light bulb, the technology content is very high, just take the power supply, the power of the lamp is only the size of the rice grain, the technician must be welded on the magnifying glass. Guo Xiaoyun said that the new product not only has a life span of 100,000 hours, but also has very low energy consumption. The 3 watt DHLEDQ60-3 can emit 60 watts of light from a conventional bulb.
Guo Xiaoyun said that after rigorous testing, DHLEDQ60-3 reached the requirements of the Tiananmen Tower's contour lights. PK lost its competitors, boarded the Tiananmen Gate Tower, and completed the installation last week.
The energy efficiency of this kind of lamp is more than 90%. If it is promoted into the family nationwide, the annual energy saved is equivalent to the annual power generation of the Three Gorges Project. Guo Xiaoyun said, however, the current lamp has not been mass-produced, and the cost is still relatively high. It should be 2-3 years after entering the ordinary family.
Made in Chongqing, the first Tiananmen Gate
In addition to the Tiananmen Contour Light, the underwater lights of the Tiananmen Square fountain and some Olympic venues have used the light source made in Chongqing. Deng Luguo, chairman of Chongqing Yuanguang Electronic Technology Co., Ltd. said.
Deng Luguo said that although the company's high-efficiency underwater lights have entered key buildings such as Tiananmen Square since 1998, it is the first time to board the Tiananmen Gate as a contour light.

What is 4G module
4G module said TD-LTE and FDD-LTE and other LTE network standards are collectively referred to. It has the characteristics of fast communication speed, wide network spectrum and flexible communication. 4G module refers to a product whose hardware is loaded to the specified frequency band, software supports the standard LTE protocol, and software and hardware are highly integrated and modular. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Second, how to use 4G module
The 4G module is usually inserted into the circuit board or the patch module is welded to the circuit board, and the corresponding SIM card is inserted, and the network is connected through the 4G cellular network. In the common transparent transmission mode, data can be directly sent to the target server through the 4G module, and the 4G module can receive data from the server at the same time, and send the data to the serial port, which is received by the serial port device connected to the 4G module. Users do not need to pay special attention to the data conversion process between serial port data and network data packets, only need to insert the module to the target position, simple connection and parameter setting, you can achieve transparent transmission between the serial port and the network end.
What is the 4G module How does the 4G module work
4G module, also known as 4G transmission module, 4G communication module, 4G LTE module. It is a kind of hardware loaded to the specified frequency band, the software supports the standard LTE protocol, and the software and hardware are highly integrated modular products, with good compatibility, fast communication speed, large amount of communication data, wide network spectrum, communication flexibility and other characteristics, widely used in electric power, environmental protection, finance, industrial automation and other fields.
The working principle of 4G module
It has the characteristics of fast communication speed, wide network spectrum and flexible communication. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Through high-speed networking, the 4G module transmits all terminal business data and equipment operating status to the business center in real time. Through the management monitoring platform, the terminal equipment operating status can be monitored in real time and equipment faults can be timely checked. The efficiency has been greatly improved in many aspects such as operating cost, operation scale and service timeliness. Suitable for shared massage chair, public charging pile, vending machine, vehicle system, environmental monitoring, power remote monitoring and other industries.

Good compatibility
4G module supports FDD LTE/TD-LTE two LTE standards, can also be backward compatible with 2G/3G, support LTE-FDD, LET-TDD, WCDMA, TD-SCDMA, CDMA, GSM and other bands.
Large amount of communication data
4G module downstream rate can reach up to 150Mbps, uplink rate can reach up to 50Mbps, to provide customers with high-speed Internet access and wireless data connection and other functions, suitable for large data transmission applications, such as: remote video surveillance.
High communication speed
The 4G module has a lower ping value than the 2G/3G module, and it takes less time for the module to send data packets to receive the response from the server, which is suitable for applications requiring high response speed, such as remote alarm.
