What are the different aspects of LED street lights different from traditional street lights LED street lamps are different from traditional street lamps. LED lamps are powered by low-voltage DC. They use GaN-based power blue LEDs and yellow synthetic white light. They have high efficiency, safety, energy saving, environmental protection, long life, fast response, and high color rendering index. applied to roads. The outer cover can be made, and the high temperature resistance reaches 135 degrees, and the low temperature resistance is 45 degrees. The design requirements of LED street lamps are as follows: 1. LEDs for lighting have the function of directional light emission, because almost all power LEDs are equipped with reflectors, and the efficiency of such reflectors is much higher than the reflection efficiency of lamps.

In addition, LED has considered its own reflection efficiency when detecting light effect. Road lights using LEDs should make use of the directional emission properties of LEDs as much as possible, so that the individual LEDs in the road lights can directly project to each area of ​​the illuminated road surface, and then use the auxiliary light distribution of the lamp reflector to achieve a reasonable combination of street lights. . It should be pointed out that road lights must truly meet the illuminance and illuminance uniformity specified in CJJ45-2006, CIE31, CIE115 and other standards, and the lamps must have the function of tertiary light in order to better realize it.

LEDs with a reflective surface and a reasonable beam output angle have a very good primary light distribution function. Inside the lamp body, the installation position of each LED and the direction of emitted light can be designed according to the height of the street lamp and the width of the road surface to achieve a good secondary light distribution function. The reflective surface in this lamp only plays the role of assisting the third light distribution to ensure better road illumination.
