Abstract

The invention discloses a novel micro-photovoltaic solar street lamp, which comprises a photovoltaic panel, a battery pack, an LED module, a digitally controlled full-bridge buck-boost circuit, a power input/output sampling circuit (5a) and a processor circuit, wherein the photovoltaic panel is electrically connected with the battery pack through the digitally controlled full-bridge buck-boost circuit; the power input/output sampling circuit (5a) is electrically connected with the photovoltaic panel and the processor circuit; the power input/output sampling circuit (5a) is used for sampling output voltage and current of the photovoltaic panel and then outputting the output voltage and current into the processor circuit for data collection; and the processor circuit is used for calculatingan optimum power point for MPPT according to the collected data and adjusting output charging voltage of the digitally controlled full-bridge buck-boost circuit, so that the photovoltaic panel chargesthe battery pack through a maximum power point. Microcurrent is collected and boosted through the digitally controlled full-bridge buck-boost circuit and is fully utilized, so that the efficiency ofconverting light energy into electric energy can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of solar street lamps, in particular to a novel micro-photovoltaic solar street lamp. Background technique [0002] Currently on the market of solar street light products, in rainy and foggy weather conditions, solar photovoltaic panels can only generate weak currents, traditional controllers cannot perform energy conversion to charge the battery pack, and the micro-current generated by solar photovoltaic panels is completely ineffective. Waste unusable. If there is continuous rainy weather for a long time, most manufacturers take measures to save battery energy by reducing the brightness of the lights. If the continuous rainy weather exceeds 20 days, the battery energy storage will be exhausted and stop working. When the front-end street lights stop working or break down, the back-end staff cannot know the status of the front-end equipment in the first place. The traditional method is to check th...
