What is the light efficiency of LED street lamps?

LED street lamp is an efficient and energy-saving lighting equipment, and its light efficiency is usually used to measure its energy utilization efficiency. Light efficiency refers to the ratio of light emitted by LED street lamps to electric energy consumed, usually expressed in lumens per watt (lm/W).

The light efficiency of LED street lamps is generally between 80- 150lm/W, which depends on the quality of LED chips, the design of driving circuit and the effect of cooling system. Higher light efficiency means that LED street lamps can generate more light with less electricity, thus achieving higher energy efficiency.

Compared with traditional fluorescent lamps and high-pressure sodium lamps, LED street lamps have higher light efficiency. The light efficiency of traditional fluorescent lamps is generally between 50- 100lm/W, and that of high-pressure sodium lamps is generally between 80-140lm/w. Therefore, compared with traditional lighting equipment, LED street lamps have higher energy utilization efficiency and lower energy consumption.

The high light efficiency of LED street lamps can not only save energy, but also reduce environmental pollution. The light of LED street lamps is more uniform and soft, which can provide better lighting effect and reduce the problems of glare and shadow. In addition, LED street lamps have the advantages of long life, strong earthquake resistance and fast response, and are the first choice for modern urban lighting.

In a word, the light efficiency of LED street lamps is generally between 80-150 lm/w. Compared with traditional fluorescent lamps and high-pressure sodium lamps, LED street lamps have higher energy utilization efficiency and lower energy consumption, which is an efficient and energy-saving lighting equipment.
