LED traffic lights can be seen almost everywhere in our use. Compared with ordinary signal lights, what are the specific advantages? Next, let the editor give you a detailed introduction:
1. The LED light source has obvious advantages in terms of energy: it can be directly converted from electricity to light with almost no heat; nearly 100% of LED traffic lights use LED visible light as excitation energy and have 80% higher heat loss than incandescent bulbs. 20% visible light.
2. The response time of LED traffic lights has significant advantages: its response speed is not as good as traditional halogen bulbs, so the use of LED traffic lights can effectively reduce the occurrence of accidents.
3. The working environment of the lamps is relatively poor, so the reliability requirements of the lamps are relatively high: the average life of incandescent lamps is 1000h, and the average life of low-voltage halogen lamps is 2000h, but the maintenance cost is high. LED traffic lights are semiconductors embedded in epoxy resin and are not easy to vibrate. , Good impact resistance, no glass breakage problem.
4. When halogen lamps are used, they are often reflected by the sun to produce virtual displays; LED traffic lights can still maintain good visibility and performance indicators under severe weather conditions such as continuous light, rain, and dust, that is, no color is required Film can produce red, yellow, and green signals; this product also has a direction and a certain divergence angle to solve the problems of phantom (commonly known as virtual display) and color changes of traditional signal lights, and improve the lighting effect.
5. The LED is directly replaced by the light source, so the heat generated is very low. The surface of the LED traffic signal light has almost no heat, avoiding burns and providing a longer service life.
The above are some of the advantages produced by the comparison between LED traffic lights and ordinary traffic lights. Although the light intensity index, electrical index and electromagnetic compatibility requirements of this product are gradually increasing, its design and circuit design also need to be further optimized to become a traffic signal. The mainstream of design!
