Specifications & Description
LED Traffic Lights Reduce Energy Use by 85%
A light emitting diode is a tiny semiconductor that emits visible light when an electric current passes through it. Unlike ordinary incandescent bulbs, there is no filament. LED traffic signals use high-brightness LEDs connected together to build a cluster consisting of hundreds of LEDs.
Typical incandescent traffic lights use 100-watt or 150-watt bulbs that are operating 24 hours a day, utilizing more than 2.4 kilowatt-hours per day. At 8 cents per kilowatt-hour, one intersection can cost almost $600 per year in electricity. Large cities with thousands of intersections spend millions of dollars on electricity just for the consumption of traffic lights. LED arrays consume 12-20 watts instead of 100, reducing overall energy consumption considerably.
Solar panels can power LED traffic lights in remote areas, reducing the costs associated with installing power lines.Another benefit of LED traffic signals is the fact that they do not burn out all at once - when an incandescent filament burns out, the entire light ceases to function, in LEDs, a single diode or a cluster of diodes can stop working or burn out, but all the other diodes operating independently will continue to function normally. This feature eliminates the safety risks and traffic congestion problems associated with burnt-out traffic signals.
LED traffic lights are more efficient and durable — retrofitting and installation is a highly successful and easily applied program for cities. There are three principle advantages to upgrading municipal traffic lights to LEDs:
1. LEDs are brighter — emitting light more evenly, making them more visible in foggy conditions.
2. LED traffic lights last for 100,000 hours, compared to incandescent bulbs, which have filaments that burn out and may last only 8,000 hours before needing to be replaced.
3. Replacing bulbs costs money and the replacement process inhibits traffic flow. Fewer burned-out lights also increase the safety of intersections.
