LED lamps with conventional HPS lamps are different, high-power LED Street lamp light source with low-voltage DC power supply, GaN based power blue LED with a yellow phosphor synthesis of high efficiency white light diodes, high efficiency, safety, energy saving, environmental protection, long life, fast response time, high color rendering index unique advantages, which can be widely applied in the urban road lighting. Cover PC made available, 135 degree heat reply. low temperature-resistant up to-45 degrees

Light emitting diode (LightEmittingDiode, abbreviated to LED) is based on the formation of semiconductor PN junction can shine with weak power efficient solid-state light sources, some under forward bias voltage and current, injection p hole and n-e after the spread to the active region issued by radiative recombination photons, direct conversion of electrical energy into light energy.
