traffic light (2)

The working environment of traffic signal lights is relatively harsh, with severe cold and heat, sun and rain, so the reliability of lamps is required to be high. The average lifespan of incandescent bulbs for general signal lights is 1000h, and the average lifespan of low-voltage halogen tungsten bulbs is 2000h, resulting in high maintenance costs. LED traffic lights have no damage caused by filament vibration, and there is no glass cover cracking problem. LED traffic lights can still maintain good visibility and performance indicators under harsh weather conditions such as continuous light, rain, and dust. The light emitted by the LED is monochromatic, so it is not necessary to use color chips to generate the signal colors of red, yellow and green; the light emitted by the LED is directional and has a certain divergence angle, which can abandon the traditional signal lights. Aspherical reflector. This feature of LED solves the phantom (commonly known as false display) and color fading problems of traditional signal lights, and improves light efficiency. Due to the important role of traffic lights in urban traffic, a large number of traffic lights need to be updated every year, which leads to a relatively large market. After all, high profits are also conducive to the development of LED production and design companies. For the entire LED industry There are also benign stimuli.
