Characteristics of LED street lights
Mar 01, 2017

LED street light is different from the normal regulations Street lamp, LED light source with low voltage DC power supply, GaN based power-efficient blue LED with a yellow synthetic white light, is an efficient, safe, energy-saving, environmental protection and long life, fast response and high color rendering index unique advantages, can be applied to roads. Housing made available, high temperature up to 135 degrees, low temperature resistant up to-45 degrees.


1, the characteristics of one-way--light, no diffusion, ensuring light efficiency.

2, LED lamp has a unique secondary optical design, LED street light to the desired lighting areas to further improve the efficiency of light in order to save energy.

3, LED is 110-130lm/W, but there is still a lot of room, the theoretical value of 360lm/W. And efficiency of high pressure sodium lamp is only increased with power, so strong overall LED street lamps light efficiency than HPS and (the overall luminous efficacy is theoretical, 250W high pressure sodium lamps light efficiency is higher than actually LED lights).

4, LED lamp light color than many HPS high, high pressure sodium lamp color-rendering index is only about 23, and LED lamp color-rendering index of more than 75, from a psychological perspective, to achieve the same brightness, LED street light illumination than an average 20% less than high pressure sodium lamps.

5, light attenuation, and light attenuation is less than 3% a year, using a 10 year road requirements, and high pressure sodium lighting failure in, for about a year has fallen 30%, therefore, LED lamps use low power design can be compared to high-pressure sodium lamps.
