LED street light: LED street light is different from conventional high-pressure sodium lamp street light. The light source of high-power LED street light uses low-voltage DC power supply, and a high-efficiency white light diode composed of GaN-based power blue LED and yellow phosphor. , Long life, fast response speed, high color rendering index and other unique advantages, can be widely used in urban road lighting.


Key points for purchasing LED street lights:

1. Luminous efficiency

  LED lighting technology is becoming more and more mature, and high-power LED light sources can already meet the luminous flux required by general street lights. The general high-pressure sodium lamp has a light efficiency of 100LM / W, and the commonly used high-power LED is 50-60LM / W. With the best foreign LED chip, it can reach 80LM / W. The higher the light emission efficiency, the better the energy saving effect. It is also one of the important indicators for selecting LED street lights. However, there is no clear stipulation in the LED standard, so you must carefully confirm when purchasing LED street lights.


2. Light attenuation of LED street lights

  Some businesses now use hundreds of 0.5W low-power LEDs to reduce costs. However, the light attenuation of this low-power LED is very serious, and its life span to 80% is only 1000 hours. Therefore, as a street lamp that needs to be used for a long period of time, it is not good to allow such low-power LEDs. If high-power LEDs (generally above 30W) are used, their light attenuation will be much better.
