Abstract

The invention discloses a photovoltaic power supply color LED lattice screen which comprises a photovoltaic battery, a Boost circuit, a storage battery, a photovoltaic power supply control part, a Buck circuit, a color LED lattice screen body and a color LED lattice screen control part. The photovoltaic cell converts solar energy into direct-current electric energy. Direct-current electric energyoutput by the photovoltaic cell supplies power to the color lattice screen part through the Boost circuit. Meanwhile, the surplus electric energy charges the storage battery. The photovoltaic power supply control part controls a Boost circuit to track the maximum power point (MPPT) of a photovoltaic cell and prevent the storage battery from being overcharged, and the Buck circuit converts the output of the Boost circuit and the storage battery into direct current (changing voltage) required by the color LED lattice screen part and prevents the storage battery from being over-discharged. The color LED lattice screen control part controls the lattice screen to display required graphics and characters in various colors and in various modes. The photovoltaic LED color lattice screen is not limited by a power supply circuit, and is energy-saving, environment-friendly, rich and colorful in display content, high in cost performance and wide in application range.

Description

technical field [0001] The invention relates to photovoltaic power generation technology and photoelectric display technology, in particular to a color LED dot matrix screen powered by photovoltaics. Background technique [0002] In the modern information society, as a new carrier of text information and graphic display, LED dot matrix screens are increasingly used in commercial centers, banks, exhibition venues, entertainment venues, buses, docks, stations, shops, etc. wider. However, the current LED dot matrix screens must rely on the grid power supply line for power supply, and cannot be used in places where the power supply line is not easy to reach; moreover, many LED dot matrix screens are currently monochromatic, and the colors are not rich enough. High-end LED screens are very expensive. [0003] Photovoltaic-powered color LED dot-matrix screen uses photovoltaic cells and batteries to power the LED dot-matrix screen, which is not limited by power supply lines; photo...
