Technical Field

[0001] This utility model relates to the field of photovoltaic glass technology, specifically a tempered laminated hollow LED reverse-mounted light photovoltaic glass. Background Technology

[0002] Photovoltaic glass, also known as "photovoltaic glass," is a special type of glass that generates electricity using solar radiation and has related current extraction devices and cables. Photovoltaic glass consists of glass, solar cells, film, back glass, special metal wires, etc., and has a wide range of applications.

[0003] However, in traditional technologies, the light emission of LED chips mounted on photovoltaic glass is greatly affected by temperature. Increased temperature will affect the light intensity of LED chips and their lifespan, thus limiting their applicability and practicality.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a tempered laminated hollow LED reverse-mount photovoltaic glass. Utility Model Content

[0005] The purpose of this invention is to provide a tempered laminated hollow LED reverse-mount photovoltaic glass to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tempered laminated hollow LED reverse-mount photovoltaic glass, comprising an installation assembly, wherein the installation assembly includes a PVB film, an aluminum heat sink, through holes, a mounting bracket, thermal grease, a locking groove, and an LED chip. The aluminum heat sink is attached to the back of the PVB film, and through holes are arrayed on the PVB film. The mounting bracket passes through the through holes, and the gap between the mounting bracket and the through holes is filled with thermal grease. A locking groove is provided in the center of the front of the mounting bracket, and an LED chip is fixed inside the locking groove.

[0007] Furthermore, the surface of the LED chip is coated with an IPO conductive layer, and the IPO conductive layer is disposed on the inside of the tempered conductive glass.

[0008] Furthermore, a LOW-E film layer is provided on the top of the PVB film, and a CIGS layer is provided at the end of the LOW-E film layer.

[0009] Furthermore, an aluminum alloy wire guard plate is bonded to the end of the PVB film with sealant, and a glass pad is provided on the inner side of the aluminum alloy wire guard plate.

[0010] Furthermore, signal lines are embedded inside the glass pad, and these signal lines are electrically connected to electronic components, which are also connected to an external power source.

[0011] Furthermore, the electronic component is screwed to an aluminum alloy frame, and an aluminum alloy cover plate is snapped into the inner side of the aluminum alloy frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In use, this application selects a CIGS layer as the light absorption layer to absorb sunlight and convert it into electrical energy. The power is supplied to the LED chip through the driving circuit built into the aluminum alloy frame. This application selects a high mechanical strength PVB film as the substrate to enhance the resistance to deformation. By filling the gap between the mounting bracket and the via on the PVB film with thermally conductive silicone grease, the heat generated by the LED chip during operation is conducted to the aluminum heat sink on the back of the PVB film through the thermally conductive silicone grease. This not only effectively ensures the heat dissipation area and improves the heat dissipation performance, but also ensures the sealing of the connection and prevents rainwater and impurities from penetrating. In use, by coating the surface of the LED chip with an ITO film, the light transmission efficiency can be improved and the light reflection and scattering can be reduced, thereby improving the luminous efficiency of the LED.
