1. Energy efficiency advantages:
Although the high-pressure sodium light source itself has a high light efficiency, up to 140 lm/W, its light source can emit 360 light, in addition to a small part of the light reflected by the reflector to the road surface to form effective light, a large part of the light is absorbed by the reflector of the lamp, no effective light is formed, the lamp efficiency is not high, combined with the power consumption of the rectifier, the effective light efficiency of the actual rectifier lamp is around 75lm/W, while the LED street lamp is unidirectional.Light emitting, high light utilization, full light effect up to 150 lm/W.Therefore, the whole-light LED street lamp is twice as effective as the traditional sodium lamp, and the The energy-saving effect is very significant.
