An LED is fundamentally a small light bulb with a semiconductor diode in place of a filament. Inside the diode, there’re positively & negatively charged areas. When a voltage is applied to the diode with the positive end hooked up to the negative site and the negative end hooked up to the positive site the electrons inside become stimulated & jump from the positively charged to negatively charged areas. This interaction generates light.
Traffic LED lamps are more competent and long-lasting — retrofitting & installation is a highly roaring and effortlessly applied program for cities. There’re 3 main benefits to upgrading municipal traffic lamps to LEDs:
• LEDs are much brighter than typical incandescent bulb—producing light more evenly, making them more noticeable in foggy or other adverse conditions.
• LED lights last for 100,000 hours, in comparison to incandescent lamps, which boast filaments that burn out & may last just 8,000 hours prior needing to be substituted.
• Substituting bulbs costs money & the replacement process obstructs traffic flow. Fewer burned-out lights also boost the security of intersections.
Advantages of switching to LED traffic light lamp also include the capability to use backup power supply for traffic signals during power cuts.
Some other advantages of LED traffic signs are:
• Large cities with thousands of intersections spend millions of dollars on electricity just for the consumption of traffic lights. These cities can enjoy considerable saving by switching to LED traffic sign.
• 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 – and this feature eliminates the safety risks and traffic congestion problems associated with burnt-out traffic signals.
• It is now possible to purchase LED in all three colors needed for traffic signals.
• Commuters now experience a reduction in travel time, less gas consumption and cost savings due to the coordination of signals. Environmentally, these strategies will result in reduced air pollution and GHG emissions from idling.
