LED street light history introduction

The history of human development is an entrepreneurial history pursuing bright, and the use of fire is an important milestone in the progress of human civilization. The bonfire lit by the ancient ancestors is the earliest light. If you think back then, would you still sigh now that the lights are booming in the ancient town of 'Lighting Capital'? Now in Guzhen, street lamp manufacturers are very professional. The so-called LED street lamp, that is, the semiconductor lighting lamp, uses light-emitting diodes as the light source. Because it is a solid-state cold light source, it has the characteristics of environmental protection, no pollution, low power consumption, high light efficiency, and long life.　　 In 1843, the first street lamp appeared on the streets of Shanghai, China. Although it was lit by kerosene, it is more holy than moonlight in people's minds. The crowds on the bank of the Huangpu River went to see the demeanor. Later, the street lights in the Shanghai Concession were changed to gas lights. It was transplanted from London, and the brightness is several times higher than that of kerosene lamps. In the eyes of pedestrians at night, it is simply the 'sun' at night. It wasn't until 1879 that China's first electric light was finally turned on at the Shanghai Pudong 16 Pier, equipped with a 10-horsepower internal combustion engine generating unit, equivalent to the power of a walking tractor.　　 On November 11, 2008, on Yingbin Road West Road, Dadukou, Chongqing, passing residents sighed, 'This street light is much brighter than before!'. It is reported that this is the first batch of LED street lights installed in Dadukou District, each with 150 watts. Compared with the original 450 watt sodium lamps, it not only saves 66.6% of electricity, but is also brighter. 'The street lights have been installed for more than 4 months, and they have been turned on for 11 hours a day. So far, there has not been one broken.' Deputy Director You of the Urban Construction Office of Dadukou District said that this pilot project is still carried out by the Municipal Economic Commission and the Municipal Finance Bureau. 'Energy saving and emission reduction' demonstration project. If the pilot is successful, it will be promoted throughout Dadukou. Assuming that there are three sections of roads in a city with lengths of 3 kilometers, 5 kilometers, and 10 kilometers, and road lights are laid every 30 meters, and one on each side, the total number of street lights required for these three sections is 202 and 334 respectively. , 668, traditional street lights are based on high-pressure sodium lamps with a power of 250W, and LED street lights are compared with a power of 50W! 　　 Road lighting is closely related to people’s production and life. With the acceleration of China’s urbanization process, LED street lights are directional , Low power consumption, good drive characteristics, fast response speed, high shock resistance, long service life, green environmental protection and other advantages have gradually come into people’s field of vision, becoming the world’s most powerful new generation of energy-saving light sources with the advantages of replacing traditional light sources. Therefore, LED Street lamps will become the best choice for energy-saving transformation of road lighting. In addition, in addition to electric street lights, there are also solar street lights. Solar street lights are a kind of street lights that use solar energy as an energy source. Because they are not affected by power supply, they don’t need trenching and burying, and they don’t consume conventional electricity. They can be on site as long as the sun is sufficient. The characteristics of installation, etc., have received extensive attention from people, and because they do not pollute the environment, they are called green products. Solar street lights can be used to illuminate urban parks, roads, and lawns, and can also be used in areas with low population density, inconvenient transportation, underdeveloped economy, lack of conventional fuels, and difficulty in generating electricity with conventional energy, but with abundant solar energy resources. People's home lighting problems. In order to play the supporting role of science and technology, promote stable and rapid economic development, focus on breakthroughs in important key technologies that restrict industrial transformation and upgrading, promote energy conservation and emission reduction, effectively guide the healthy and rapid development of semiconductor lighting applications in my country, expand the scale of semiconductor lighting market, and stimulate consumer demand. Promote the improvement of the industry's core technology research and development and innovation capabilities, and rapidly enhance the overall competitiveness of my country's semiconductor lighting industry, our manufacturers should strive forward. Produced by Guangdong Zhongshan Guzhen Pinhua Lighting Co., Ltd., it is a professional street lamp manufacturer. As the world's most eye-catching new generation of light source, LED street lamps have high brightness, low heat, short-lived, non-toxic, recyclable and reusable. Advantages, known as the most promising green lighting source in the 21st century.
