What are traffic lights?
Navigation lights have used LEDs as light sources for many years. The current work is to improve and perfect. Road traffic lights have made great progress in recent years, with rapid technological development and rapid application development. There are currently about 40,000 sets of orders in China each year. In California, the United States replaced 50,000 sets of traditional light source signal lights with LED traffic lights in the last year. According to the use effect, the long life, power saving and maintenance-free effects are obvious. At present, the peak wavelength of the LED light emission is red 630nm , Yellow 590nm, green 505nm. The problem that should be paid attention to is that the driving current should not be too large, otherwise the high temperature conditions under the summer sun will affect the life of the LED.
Recently, LED airport-specific signal lights used in airports as beacon lights, floodlights and omnidirectional lights have also been successfully and put into use, and the results have been very good. It has independent intellectual property rights, has obtained two patents, and has good reliability. It saves electricity and is maintenance-free. It can be popularized and applied to various airports to replace the old signal lights that have been used for decades. Not only is the brightness high, but because the LED light color purity is good, it is particularly bright and easy to recognize.
Railway signal lights require different light intensity and viewing angles due to their large variety series. They are currently being developed rapidly. It is estimated that they will gradually be successfully developed and put into application. In terms of quantity, it is also a fairly large market.
