The advantages of LED applications in signal lights are as follows:

  1. Monochromatic light, with divergence angle

  The light emitted by the LED is monochromatic, so there is no need to use color chips to produce red, yellow, and green signal colors; the light emitted by the LED is directional and has a certain divergence angle, which can abandon the traditional signal lights. Aspherical mirror. This feature of LED solves the phantom (commonly known as false display) and color fading problems of traditional signal lights, and improves the light efficiency Light Emitting Diode In-line.

  2. Cold light source, low energy consumption

  The advantages of LED Light sources in terms of energy saving are very obvious. One of its notable features is low energy consumption, which is of great significance to the application of lamps High-power LED.

  3. Good reliability and long life

  The working environment of the signal lamp is relatively harsh, with severe cold and heat, sun and rain, so the reliability of the lamp is relatively high. The average lifespan of incandescent bulbs for general signal lights is 1000h, and the average lifespan of low-voltage tungsten halogen bulbs is 2000h, which results in high maintenance costs. In actual use, many LED traffic lights have been used for more than 5 years, and the LEDs have not been damaged. Another big advantage is that the tungsten halogen bulbs are not as fast as the response time, thereby reducing the occurrence of accidents LED light strip.
