Description

Technical Field

[0001] The invention relates to the field of photovoltaic power generation and lighting, and in particular to a photovoltaic and LED light-emitting component. Background Art

[0002] In the field of LED luminous glass, the laser engraving circuit of conductive film glass is widely used. The dot matrix LED circuit is formed by laser engraving circuit. Through a certain production process, dynamic display screens and billboards of different formats can be produced. The power supply used is AC power, which is converted as the power supply of LED luminous glass through a switching power supply.

[0003] In the field of photovoltaic power generation, there are amorphous silicon, polycrystalline silicon and monocrystalline silicon cells. Currently, the most mainstream applications are polycrystalline silicon and monocrystalline silicon cells. Among them, monocrystalline silicon cells have the highest photoelectric conversion efficiency and can be used in ground power stations and building-integrated power generation.

[0004] In summary, both have certain limitations. The main application areas of LED luminous glass are display screens and billboards. It is a pure energy-consuming product, and its application areas are relatively specific and narrow. For example, it is difficult to use it as a glass curtain wall when integrated with buildings. It is subject to manufacturing costs and building energy conservation and consumption reduction requirements. Its advantage is high light transmittance, and its disadvantage is that it has no decorative effect during the day. Photovoltaic cells are green and environmentally friendly power generation products. Compared with LED luminous glass, they can be used in photovoltaic building integration, but they still have shortcomings in some specific applications. For example, it is difficult to achieve lighting in the atrium and sloping roof of a building and at night. Although photovoltaic cells can generate electricity, they cannot illuminate at night. Taking existing products as an example, they have almost no light transmittance even during the day because the silicon wafers are closely arranged.

[0005] If there is a component product that combines the two, it can not only generate electricity, but also be used for lighting and as a display screen, and has a certain light transmittance and decorative effect, it meets the national requirements for energy conservation and emission reduction in buildings and has more application areas.
