Problems faced by LED traffic lights
1. The application of high-power LEDs has the advantage of greatly reducing the number of LEDs, but heat dissipation and cost are problems that need to be solved.
2. Although the light intensity index, electrical index and electromagnetic compatibility requirements of LED traffic lights are gradually improving, the optical design and circuit design of LED traffic lights still need to be further optimized to become the mainstream of traffic signal design.
3. With the improvement of energy-saving and environmental protection requirements, the signal light combining LED and solar energy will be popularized, but the problem of cooperation with the traffic signal controller needs to be solved.
All in all, the application of LED in traffic lights has developed very rapidly, and the market prospect of LED application in the field of transportation is also very good, and it has basically replaced traditional light sources. Although the traffic signal products on the market are close to saturation, due to the advantages of LED itself, such as environmental protection, energy saving, long life, etc., the application of LED in the field of transportation still has a very large space.
