Solar traffic light
Solar traffic lights are signalling devices powered by solar panels positioned at road intersections, pedestrian crossings and other locations to control the flows of traffic. They assign the right of way to road users by the use of lights in standard colors, using a universal color code. Most of the solar traffic lights have battery back-up for functioning during night.
Features
solar traffic lights use LED lamps as they are more reliable and have more advantages over other lighting devices like CFL lamps as they are more energy efficient, have a longer life span and turn on and turn off quickly. Solar traffic lights contain enclosures which house the batteries and the control panel circuitry. Existing solar panels can also be upgraded with an auxiliary power source using solar panels for use during power failures. The other parts in a solar traffic light include a charge controller to control the charging and discharging of the battery and a countdown timer which displays the amount of time left before the battery discharges fully.Solar traffic lights can also be used during periods following natural disasters, when the existing street lights may not function due to power outages and the traffic is uncontrollable. Street lights used in such scenarios are designed to be portable enough to be carried and operated by police and relief workers wherever traffic needs to be regulated.If you’ve invested in solar power for your property then you’re probably sitting back and enjoying the benefits! Unfortunately solar panels do require maintenance, something you may not have realized until you were researching; many people aren’t aware that solar panels to require specific care. One of the easiest and least expensive ways to maintain the health of your solar panels is through cleaning. Simple cleaning procedures will ensure that your solar panels are in the best shape possible.
