The street lights of Led street lights Manufacturers(CLASSIC) https://www.classicledlight.com/
are different from traditional high-pressure sodium lamps. High-power LED street light adopts low-voltage DC power supply. It uses Gan Power blue led and yellow phosphor to synthesize high-performance white light-emitting diode. It has the characteristics of high efficiency, safety, energy saving, environmental protection, long life, fast response and unique color index. Can be widely used in urban road lighting. The outer casing can be made of PC tube, with a high temperature of 135 degrees and a low temperature of 45 degrees.
A light-emitting diode (abbreviated as LED) is a highly efficient solid-state light source that emits weak power based on a semiconductor PN junction. In a certain positive bias and injection current, the holes injected into the P region and the electrons injected into the N region emit photons after being diffused into the active region by radiation, and the radiation directly converts the energy into light energy.
Advantages of LED street lights:
Features of LED street light itself - One-way, no light diffusion, ensuring light efficiency.
LED street light has two unique optical designs, which will illuminate the led street light to the required lighting area to further improve the lighting efficiency to achieve energy saving.
The efficiency of LED light source has reached 110-130lm / w, and there is a lot of room for development, the theoretical value is 250lm / w. The luminous efficiency of the high-pressure sodium lamp increases with the increase of power. Therefore, the overall luminous efficiency of the LED street lamp is higher than that of the high-pressure sodium lamp; (this overall luminous effect theoretically, the light efficiency of the high-pressure sodium lamp exceeding 250 W is actually higher than that of the LED).
The color of the LED street light is much higher than that of the high-pressure sodium lamp. The color index of the high-pressure sodium lamp is only about 23, and from the street color index to 75 or more, from the visual psychological point of view, to achieve the same brightness, the LED street lamp illumination can be higher than the high-pressure sodium lamp. The average is 20% lower (refer to the UK Lighting Standards Principle).
Light decay is small, the light decay is less than 3% in one year. It still meets the road use requirements after 10 years of use, while the high-pressure sodium lamp has decreased by more than 30% in one year. Therefore, the use of LED street lamps in power supply design can be lower than that of high-pressure sodium lamps.
