Solar Powered Energy Utilization Module

The solar-powered energy utilization module works during the day. The solar photovoltaic panel uses the photovoltaic effect of the solar cell semiconductor material to convert solar radiation into electrical energy. The solar controller stabilizes the voltage at 24 V and the current at 0.6±0.05A and inputs it to the stored solar battery. When light is needed at night, the solar battery supplies power to the Led Street Light to realize the function of street lighting. When designing solar photovoltaic panels, it is necessary to select photovoltaic cell arrays with high photoelectric conversion efficiency; when designing solar batteries, the selection of battery capacity is the key. When designing the controller, it is necessary to select a low-power controller while maximizing the output power of the solar photovoltaic panel.

Wind power supply energy utilization module

The wind energy power supply energy utilization module converts wind energy into electric energy and supplies power to the light source of the advertising lightbox on the street lamp. When the wind speed reaches 3 m/s, the generator outputs electric energy, and the wind energy generator passes the wind energy controller to stabilize the voltage at 12V, the current is stable at 0.6±0.05A, and then the electric energy is stored in the wind energy battery, and the wind energy battery provides electric energy for the advertising lightbox at night to realize the function of street lamp beautification. Because wind power generation has more instability than solar power generation when designing the device, the electric energy of wind power generation is stored in the wind energy battery, and the solar battery and the wind energy battery are used separately without interfering with each other; the battery capacity when designing the wind energy battery It is required to be able to meet the nighttime beautification lighting needs of advertising light boxes; compared with the horizontal axis wind energy generator, the vertical axis wind energy generator has the advantages of high power generation efficiency, low starting wind speed, and no requirement for wind steering. Therefore, LED-based on multi-energy utilization. When Street Light is used in areas with low wind power density, vertical axis wind energy generators should be used for wind energy generators.

Waste heat recovery and utilization power supply energy utilization module

Led Street Light will generate a lot of waste heat when working. This part of the waste heat not only affects the life of the Led Street Light but also causes energy waste if it is not used. Recycling the waste heat of Led Street Light through semiconductor thermoelectric power generation technology is the most effective way. The core component of the semiconductor thermoelectric power generation technology is the semiconductor thermoelectric power generation patch, which is made of PN junctions made of compound materials in parallel. The lamp bead aluminum substrate of Led Street Light is attached to the high-temperature surface of the semiconductor thermoelectric power generation patch. When the LED street lamp is working, the heat is transferred from the high-temperature surface to the low-temperature surface. During the heat transfer process, the temperature of the high-temperature surface is affected by the working waste heat of Led Street Light. Its temperature is higher than that of the low-temperature surface, and a stable temperature difference is formed between the high-temperature surface and the low-temperature surface. Due to the See beck effect of the semiconductor thermoelectric power generation patch, part of the heat will be converted into electrical energy output during the heat transfer process. The lower heat is dissipated into the air by the radiator after passing through the low-temperature surface.

The above is the design of Led Street Light with multiple energy utilization. If you are interested in Led Street Light, you can contact us. Our website is https://www.bestshowled.com/.
