Characteristics Of LED Street Lights

LONGT Lighting Group Co.,Ltd | Updated: Dec 11, 2015

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.

Advantages


1, their own characteristics--the one-way, there is no diffusion, ensuring light efficiency.

2, LED lights have 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 has reached 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 lights 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 the road 10 years required, and failure in high pressure sodium lights, about a year has declined by more than 30%, therefore, LED lamps use low power design can be compared to high-pressure sodium lamps.

6, energy-saving LED street light control device, able to meet different lighting requirements of the greatest possible power, saving energy. Computer dimming, time control, light control, temperature control, automatic inspection functions.
