High-frequency discharge system for solar outdoor street lamp

Abstract

The invention discloses a high-frequency discharge system for a solar outdoor street lamp, and specifically relates to the field of solar power generation. The system comprises a solar module, an electric energy storage device, a PWM controller and an LED lamp, wherein a high-frequency discharge device is connected between the electric energy storage device and the PWM controller, the high-frequency discharge device is used for detecting the stored electric quantity of the electric energy storage device, calculating the electric quantity required by the LED lamp, and controlling the dischargequantity by adopting a stepped discharge method. According to the invention, stepped discharge regulation and control are carried out according to the capacity of the storage battery and LED parameters by adopting the high-frequency discharge device is adopted, the limited electric quantity generated in the electric energy storage device can be used to a greater extent, the phenomenon that the street lamp is powered off due to the fact that the electric quantity generated in rainy days is small is avoided, the whole system can use equal electric quantity output to generate the effects of increasing the illumination brightness and the illumination range, the electricity consumption can be reasonably reduced, and the system is mainly used for outdoor equipment of solar integrated street lamps and garden landscape lamps.

Description

technical field [0001] The embodiment of the present invention relates to the field of solar power generation, in particular to a high-frequency discharge system for solar outdoor street lamps. Background technique [0002] Solar power generation is a device that uses battery components to directly convert solar energy into electrical energy. Solar cells are solid devices that use the electronic properties of semiconductor materials to achieve P-V conversion. In the vast areas without power grids, this device can conveniently realize lighting and life power for users. Some developed countries can also be connected with regional power grids. Grid-connected to achieve complementarity. At present, from the perspective of civilian use, the "photovoltaic-building (lighting) integration" technology that has matured and has begun to be industrialized abroad is mainly researched and produced in China for small-scale solar power generation suitable for household lighting in areas wi...

Problems solved by technology

[0006] To this end, the embodiment of the present invention provides a high-frequency discharge system for solar outdoor street lamps. By adopting a high-frequency discharge device and performing stepwise discharge regulation according to the battery capacity and LED parameters, the limited power generated in the electric energy storage device can be reduced. The maximum use of power can solve the phenomenon of power outages caused by the low power generated in rainy days. The whole system can use the output of equal power to produce the effect of increasing the brightness of the light and increasing the irradiation range, and can reasonably save power. Consumption, in order to solve the problem that in the prior art, due to the influence of solar power generation by rainy weather, it is impossible to illuminate around the clock and affect the brightness of lighting
