LED street lamp light source advantage than traditional street lamp light

The lights LED as the light source, compared with traditional street lamps light source, it has many advantages first, LED is a semiconductor diode, its life is very long. When the flux decay to 80%, its life up to 25000 hours. And the life of the metal halide lamp in 6000 ~ 12000 small

the lights LED as the light source, compared with traditional street lamps light source, it has many advantages first, LED is a semiconductor diode, its life is very long. When the flux decay to 80%, its life up to 25000 hours. And the life of the metal halide lamp in 6000 ~ 12000 hours, high pressure sodium lamp life 12000 hours. Secondly, the basic structure of the LED is an electroluminescent semiconductor materials, placed on a wire rack, then sealed with epoxy resin around, protect the internal core, so the LED seismic performance is good. Thirdly, white LED light color is better than high pressure sodium lamp. In the middle level of the visual, the human eye in high temperature environment than low colour temperature environment are more likely to identify things. Color rendering of white LED is much better than high pressure sodium lamp, high-pressure sodium lamp color rendering index only 20 left, right and white LED can reach 65 ~ 80. Fourthly, LED dimming function can realize the perfect. Due to the LED work scope is bigger, its light output and the working current is proportional to, so can reduce the current method to adjust the light. In addition, because the LED to frequent switch without too much damage to its, LED dimming can also adopt the method of pulse width adjustment to get, by adjusting the duty ratio of voltage and working frequency, and can effectively adjust the luminous intensity of LED. Fifth, in the optical system of lamps and lanterns, LED light source of luminous flux loss the school different from the traditional light source, LED is half space illuminated light source. High pressure sodium lamp or metal halide lamp is illuminated light source, whole space needs to be one and a half space of emergent light change 180 & # 8226; • • The direction to the other half space. When we rely on the reflector to complete, reflector to absorb the light and the light source itself against light is inevitable. And use the LED as light source, no losses in this regard, the utilization rate of light is higher than the traditional light source. Finally, the LED light source does not contain harmful metallic mercury, unlike high pressure sodium lamp or metal halide lamp when scrapped cause harm to the environment.
