In Luquantun Town, a pilot town reforming administrative system in Shandong Province, there is a 3.5km road constructed according to the national first-class standard, and 360 LED solar street lights are installed on both sides. This is the gateway to the construction of the Central Air Conditioning Accessories City. Honghai Road. At night, the lights were bright and the reporter felt the pace of the transformation of the town into the city. 'Because of the lighting of these LED solar street lights, the builders of Luquantun have the spirit of using the night as a daytime officer, which has made Luquantun a construction speed. Lu Zhiquan town party secretary Tian Zhiqing said. Indeed, Shandong Dezhou Energy Photonics Technology Co., Ltd.'s independently-innovated low-power LED solar street lights contributed to the reform and development of Luquantun Town.
In recent years, more and more urban street lamps use solar high-power LED (greater than or equal to 1W) lighting technology. However, this technology is often due to low heat dissipation efficiency, light efficiency conversion is only about 50% -60%, directly affect the luminous efficiency and service life of the lamps. The low-power LED (0.06W) lighting system does not need to install heat sink, the system cost is reduced by more than 40%, light efficiency conversion can reach more than 90%, the light source brightness is 5-10 times higher than the traditional high-pressure sodium lamp, is a high-power LED lamp 2-3 times the service life of more than 50,000 hours, significant energy savings. The company that overcomes such a world problem and scales production is the German Energy subsidiary.
In 10 years, Xue Huanzhang, chairman of Dequan Energy's subsidiary, led his scientific research team to overcome many difficulties. After repeated testing and improvement, he has mastered a set of constant current drivers for solar energy low-power LEDs that are used in various environments. There are core intellectual property technologies. Because there is no need to install a heat sink, it solves the problem of low-power LED heat dissipation; it achieves 2000 hours without attenuation, 10,000 hours attenuation does not exceed 6%, and 50,000 hours attenuation does not exceed 20%; low-power LED energy storage battery in - Both the 40°C and the 60°C can work normally, and can be normally lighted for 7 to 15 days under a condition of no sunlight.
Xue Huanzhang told reporters that because of the advantages of solar energy low-power LED products, it can be said that the same power, the brightness of the low-power LED is the highest; the same brightness, the power of the low-power LED is the smallest; the same conditions, the life of the low-power LED is the most long.
On Honghai Road, the reporter observed that other companies installed solar high-power LED lamps with the same price and standard, and the lighting effects were very different from those of Solar Energy's solar energy low-power LED lamps. Under high-power LED lights, the road is a black and white zebra, and the brightness of the far-away light is dim. The energy-subsidiary company's solar low-power LED lights shine brightly on the road. Liang Baoqiang, research and development director of the company, introduced that single-power high-power LED production of 1-5 watts are embedded in the lamp LED, through the metal head to achieve the purpose of heat dissipation, its life and luminous flux with the temperature increases inversely. The core technology of the German energy subsidiary company is to set the LED on the self-cooling circuit board through the designed circuit combination. When a single low-power LED does not emit light, it does not affect the normal light emission of other diodes on the board; when the circuit board is strained or When other reasons cannot be used, the entire circuit board can be directly replaced for easy maintenance.
At present, the company's solar power low-power LED system integrated module has won three national invention patents, more than a dozen utility model patents; has successfully developed dozens of models of solar power LED lights and solar power low-power LED shelters. Products are widely used in Shandong, Guangxi, Jiangsu, Zhejiang and Inner Mongolia. Right now, the company is stepping up production of low-power LED garden lights and street lamps customized for Germany, Malaysia, South Africa and other markets. In July alone, it signed a sales contract of 20 million yuan. Xue Huanzhang said that solar thermal power is not used in combination with AC and DC, and lighting is less than 6 hours. We will strive to achieve sales of 150 million yuan in the next year and be listed in the United States within 1-3 years.
