Traffic light

Traffic signal lights have been around for years and are used to efficiently control traffic through intersections. A traffic signal lamp is used to control vehicles and passengers so that traffic can flow smoothly and both drivers and passengers are safe. Traffic signal lights are generally comprised of an enclosure that houses green, amber and red lights. Conventional traffic lights employs red, yellow and green filters over incandescent bulbs that are sequentially turned on and off by an electromechanical timing switch or by solid state controllers. Each bulb is electrically coupled to a conventional power source, such as the conventional power distribution network. In recent years, light emitting diode (LED) lamps have been developed to replace conventional incandescent or fluorescent lamps for reducing electrical and maintenance costs, and for increasing reliability. LEDs offer the considerable advantage of consuming significantly less power than incandescent lamps. LEDs also generally require less frequent replacement due to burn out than incandescent lamps. LED traffic signal lights can be designed to produce, with normal line voltage, the same light intensity as incandescent bulbs that are currently used, and to have comparable performance characteristics for different viewing angles. LED bulbs, in short, offer a desirable reduction in power and maintenance costs as compared to incandescent lamps.
