Ciscoloration and customers, improve the efficiency of light
1, monochromatic light having a divergence angle
Monochromatic light emitted from the LED, and thus do not need to customers color film to produce red, yellow and green color signals; light emitted by the LED direction,, and a certain divergence angle, which can be used instead of the traditional lights aspheric mirrors. This feature of LED lights to solve the traditional presence of the phantom (commonly known as false display) and color film fading problems, improve the optical efficiency

2, cold light source, low energy consumption Advantages in energy saving LED light source is very obvious, one of its notable feature is the low power consumption, which in terms of lighting applications is significant.

3, good reliability, long life Lights work environment is relatively harsh, cold summer, sun and rain, and thus higher reliability requirements lamps. The average life expectancy is generally lights with incandescent bulbs is 1000h, the average life expectancy low voltage halogen bulb is 2000h, high maintenance costs arising therefrom. In actual use, there have been many LED traffic lights use the time more than five years, and no damage to the LED. There is a relatively large advantage is less than halogen bulbs, etc. are fast response time, thereby reducing the occurrence of post accident. Several problems on the LED traffic signal lamp:

1,The high power LED applications,, high power LED has the advantages of greatly reduced the number of LED, but the problem that needs solving heat dissipation and cost.
2, although the electrical parameters and electromagnetic intensity index, LED traffic signal lamp compatibility requirements gradually improved, however, optical design, LED signal lamp circuit design also needs further optimization, in order to become the mainstream of traffic signal lamp design.
3, with energy saving, environmental protection requirements increase, LED signals with the combination of solar energy will be popular, but need to solve the matching problem and traffic signal control machine.

In a word, the application of LED in the traffic signal lamp, its development is very rapid, and applications used in the transport sector is also very good market prospects have basically an alternative to traditional light sources. Although the traffic signal products on the market has been close to saturation, but because LED has the environmental protection, energy saving, long life and other advantages, the application of LED in traffic field still has very large space.
