led street light fixture Function of the lamp holder
led street light fixture is a semiconductor lighting fixture. It is a solid state light source based on semiconductor PN junction, which can emit light with weak electric energy. It has the characteristics of environmental protection and pollution-free, low power consumption, high light efficiency and long life.
1, street lamps are an important part of urban lighting, traditional street lamps often use high-pressure sodium lamps, high-pressure sodium lamps 360-degree light, light loss caused by the shortcomings of a huge waste of energy;
2, the global environment is deteriorating day by day, and all countries are developing clean energy. The development of new, energy-saving, long life, high color rendering index, environmental protection led street light fixture is of great significance for city lighting energy saving;
3, road lighting is closely related to people's production and life. With the acceleration of China's urbanization process, led street light fixture has the advantages of directional lighting, low power consumption, good driving characteristics, fast response speed, high seismic ability, long service life, green environmental protection and so on. It has become a new generation of energy-saving light source with the advantages of replacing traditional light sources in the world.
1, the characteristics of the fixture head itself -- one-way light, no light diffusion, to ensure light efficiency;
2, led street light fixture head has the most special secondary optical design, the light of led street light fixture head to the required lighting area, further improve the lighting efficiency, in order to achieve the purpose of energy saving;
3, the light color rendering of led street light fixture head is much higher than that of high-pressure sodium lamp.
4, LED light source efficiency has reached 90-110LM/W, and there is a lot of room for development, the theoretical value of 250lm/W.
led street light fixture Aluminum alloy shell has the advantages of high strength, good shape, easy processing and good electrical and thermal conductivity, and there is still a lot of room for development.
