LED street lighting is an important part of urban lighting
The environment is deteriorating, and all countries are developing clean energy. And with national economic growth, the energy increasingly prominent contradiction between supply and demand in China, the country's electricity supply began to appear the situation of serious shortage, energy conservation becomes the urgent problem. Therefore, it is of great significance to develop new high efficiency, energy saving, long life, high color index and green LED street light.
Road lighting is closely related to people production and living, with the most began to speed up the process of urbanization in our country, the LED street light with a directional light, low power consumption, good drive performance, fast response, high seismic ability, long service life, and the advantages of the green environmental protection gradually into people's horizons, has now become the world's most replacement of traditional light source with advantages of a new generation of energy-saving light source, therefore, the LED street light will become the best choice of the road lighting energy saving reconstruction.
LED is the light source that illuminates half space, and the light source such as traditional high pressure sodium lamp and gold halogen lamp are all illuminative to whole space. From the envelope on the surface of the reflector of light emergent Angle to compare, a large part of the traditional source light is required to pass through the optical system to exit after reflection or refraction, optical system for light use efficiency determines the overall efficiency of lamps and lanterns, the traditional light source and the volume is larger, due to the absorption and reflection light 2 times and reduce the efficiency of lamps and lanterns. LED has the characteristic of luminescence to the plate space, so that the proportion of light absorption to the light is greatly reduced, which is one of the advantages of LED lamps in the efficiency of lamps.
Road lighting is an important means of can let the city looks more beautiful, but in the past the traditional street lamp is usually made of high pressure sodium lamp 360 degrees, the light source is not centralized, spread out light let street lamp looks not so bright, this is for the one huge waste of energy.
In now has also appeared in the global energy shortage, energy problem is becoming more and more serious, for this is to avoid unnecessary loss, so in the development of new clean energy, with the development of the country, power shortages will become a problem, it needs to be a kind of light source concentration, energy conservation, environmental protection, and long service life of a kind of lamps and lanterns, LED street light is in accordance with all even beyond new street light, LED street light is for a city is of great significance, the key point of popularity.
