What are the problems of solar light street lamp with sensor in low temperature?

          Although solar light street lamp with sensor have many advantages and are widely used, they are very popular. But it should also have some problems with him.What are the problems of solar light street lamp with sensor in low temperature environment?

         The minimum cross-sectional area of the wires used on solar light street lamp with sensor is greater than 0.5 mm2. In cold environments, too low a temperature may cause the wire below this standard to crack, resulting in a short circuit, causing the wire to burn and the insulation to burn out. Therefore, it is necessary to use a wire larger than 0.5mm2 to avoid this safety hazard. The solar street light with panel should be set according to the temperature variation characteristics of the solar street light with panel in a specific use environment, and the packaging process parameters such as the ultrasonic power, the bonding pressure, the bonding time and the bonding temperature are set. The solar street light with panel component with simple shape structure, compact structure, surface waterproofing and excellent hydrophobic performance is selected. One problem that cheap solar street lights are often overlooked by solar LED street lamp manufacturers in cold regions is that ice and snow accumulate on the surface of solar LED lamps. Once formed by the melting of ice,will have a very large safety hazard for vehicles and pedestrians. Especially for cheap solar street lights, since the lamp housing is generally made of aluminum, the surface of the alumina is a hydrophilic material, which is more likely to cause ice condensation. In order to avoid this safety hazard, it is necessary to use solar LED lamp components with simple structure, tight structure, surface waterproof and excellent hydrophobic performance.

         The solar powered outdoor street lights contains a battery. The operating temperature of the gel battery or lithium battery is -40 ° C ~ 60 ° C. In low temperature environments, the performance of the battery will also drop, so choose a reliable supplier of solar powered outdoor street lights batteries.
