Introduction and characteristics of LED street lights
LED street lights
have gradually entered people's field of vision with the advantages of directional light emission, low power consumption, good driving characteristics, fast response speed, high shock resistance, long service life, green environmental protection, etc. Energy-saving light source, therefore, LED street lights will become the best choice for energy-saving renovation of road lighting. LED street lamps are semiconductor lighting lamps, which use light-emitting diodes as light sources. Because they are solid-state cold light sources, they are environmentally friendly, pollution-free, low power consumption, high luminous efficiency, and long life.
LED street light features:
The difference between LED street lamps and conventional high-pressure sodium lamps is that the light source of high-power LED lamps adopts low-voltage DC power supply, high-efficiency white light diodes synthesized by GaN-based power blue LEDs and yellow phosphors, which are efficient, safe, energy-saving, environmentally friendly and have long life. , fast response, high color rendering index unique advantages, can be widely used in urban road lighting. The outer cover can be made of PC tube, which can withstand high temperature up to 135 degrees and low temperature up to -45 degrees.
Light Emitting Diode (LED for short) is a high-efficiency solid-state light source based on a semiconductor PN junction that can emit light with weak electrical energy. Under a certain forward bias voltage and injection current, the holes and The electrons injected into the N region diffuse into the active region and then emit photons through radiation recombination, which directly converts electrical energy into light energy.
