This is the era when LED street lamps replace traditional street lamps: the life of traditional metal halide lamps is 15,000 hours, and the life of LED street lamps is 60,000 hours. Compared with traditional lamps, LED street lamps have better shock resistance. In addition, the color rendering index of the low-pressure sodium lamp is 5, the color rendering index of the mercury lamp is 17, the high-pressure sodium lamp is 24, and the color rendering index of the LED street lamp is 70. The higher the color rendering index, the better the reducibility of the object, which effectively improves road safety. The lenses used in LED street lights are also particular. The glass lenses used by LED street light factories are combined with LED light sources to achieve light distribution, which makes the road surface light uniformity even higher. Comparison of LED street lights and traditional lights What effect do different lenses have on LED street lights? PMMA lenses have high production efficiency, but the temperature cannot exceed 80 degrees, which is easy to deform at high temperature. Silicone lenses are resistant to high temperatures and are relatively small. PC lens production efficiency is also high, but the light transmittance is slightly lower, the temperature cannot exceed 110 degrees, and high temperature is easy to deform. Glass lenses have high light transmittance and high cost. The non-fragile properties of glass can be improved through tempering, and it is considered to be the lens with the most prospects. Xiangruilight LED street lamp has developed a patented eccentric street lamp lens with a light transmittance greater than 93%, a larger light area, effectively reducing dark areas on the road, less light pollution, and heat-resistant aging. The lens can affect the effect of light. The light of some LED street lights is likely to cause light pollution, making the night sky into a neon color. Light pollution will further affect air quality and human health. The lens developed by the Led Street Light Factory is a bat-shaped light spot with a light emitting angle of 120 ° / 130 ° / 140 ° / 150 °, which not only makes the illuminated area larger, but also effectively reduces light pollution.
