MELa -s Full Solar Powered Street Light with 13” E-paper Solution
MELa Outdoor solar powered Lamp Post serves as an excellent quick win for any smart city to include in its plans and with a sound ROI. It uses full solar power by Solaradtek to power the top LED Lights and a one to two 13" epaper screens by eink. During the day time, solar panels generate DC power, it passes through the controller to charge the battery, when it becomes dark, the controller detects no sun light then it gives an order to the LED lamp to turn ON, and the lamp will turn OFF again once the controller detects sunlight. In case of a non-sun rainy day while no current is coming out of the panel for the whole day, the controller is pre-set to turn ON the lamp for a certain amount of hours using the backup capacity of the battery which could be determined upon customer’s request. The 13" epaper has an internal back up battery that will last it a whole year if not connected for any reason with the solar panel. The epaper screen provides remote continuous content feed when needed with community news, bus and train passenger updated schedules and commercial advertising.
The unit is rated at IP67 and can operate in environments with temperatures varying from -30°C ~ 60°C (-22°F ~ 140°F).
