Abstract

The invention relates to a PV-LED (Photovoltaic-Light-Emitting Diode) solar-battery illuminating device, which comprises a PV-LED solar-battery assembly, an inverter and a storage battery, wherein the PV-LED solar-battery assembly is formed by laminating and packaging glass, EVA (Ethylene-Vinyl Acetate), a solar-battery pack, the EVA, PET (Polyethylene Terephthalate), an LED lamp group, the EVA, the glass and an auxiliary material, wherein the solar-battery pack is used for outputting the received current generated by sunlight to the inverter, the inverter is used for outputting the current to the storage battery, and the storage battery is used for supplying electricity for the LED lamp group for illumination. In the PV-LED solar-battery illuminating device disclosed by the invention, electricity-generating equipment and illuminating equipment are integrated into the same device, the electricity is generated by utilizing a solar battery under the irradiation of the sunlight at daytime, electrical energy is converted into chemical energy to be stored in the storage battery, and the illumination is supplied for an energy-saving type LED lamp at night, so that the consumption of other energy sources is saved through a circuit design; and double-surface glass packaging is utilized by the device, and the building requirements for both structural strength and heat-preserving performance can be met. The PV-LED solar-battery illuminating device can be combined with buildings to be used as a ceiling or a floor brick; and the PV-LED solar-battery illuminating device not only can be used as a good building material, but also can be used for novel landscape decoration.

Description

technical field [0001] The invention relates to a solar cell, in particular to a PV-LED solar cell illuminating device and an application thereof. Background technique [0002] The core component of the solar cell is the semiconductor PN junction, which uses the photovoltaic effect to generate electromotive force on both sides of the PN junction, and directly converts light energy into electrical energy; solar cell power generation does not emit harmful gas and dust, and is clean and environmentally friendly. It is the most developed in the 21st century. One of the potential new energy industries. Conventional solar cells adopt glass-EVA-cell-EVA-insulating back film five-layer packaging process. The structure of the component is simple and the function is single. It can only convert light energy into electrical energy, and realize the output of electrical energy with an external cable. Electric energy cannot be converted into other forms of energy; conventional independent...
