Description

Technical Field

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

[0002] LED photovoltaic glass is a composite photovoltaic building material that combines light energy, electrical energy, and glass. It is a product that perfectly combines LED, photovoltaic, and glass, breaking through the traditional concept of building decoration materials. It can generate electricity using photovoltaics during the day and provide lighting using LEDs at night, thus improving the practicality of photovoltaic glass.

[0003] For example, utility model publication CN205882729U discloses an LED photovoltaic glass. This utility model directly bonds photovoltaic glass to conductive glass and directly connects it to the glass's own energy storage and transformation system, realizing its own DC storage and the transformation and grid-connected generation of excess electricity. This reduces wiring entanglement, facilitates installation, and improves environmental protection and energy-saving effects. However, in actual use, there is a certain gap between the LED beads. The light is brighter near the beads, while the light between two LED beads is dimmer, resulting in uneven light distribution that affects the viewing effect.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a tempered laminated LED photovoltaic glass. Utility Model Content

[0005] The purpose of this invention is to provide a tempered laminated LED 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 LED photovoltaic glass, comprising tempered conductive glass and a microlens array sheet. An ITO conductive layer is disposed on the top of the tempered conductive glass, and LED beads are embedded within the ITO conductive layer. The microlens array sheet is disposed within the tempered conductive glass. A PVB film is disposed on one side of the ITO conductive layer, and a front electrode layer is connected to one side of the PVB film. A high-resistivity layer is disposed on one side of the front electrode layer, and a buffer layer is connected to one side of the high-resistivity layer. A CIGS layer is disposed on one side of the buffer layer, and an MO back electrode is connected to one side of the CIGS layer.

[0007] Furthermore, the microlens array sheets are arranged in a row about the top of the tempered conductive glass, and each microlens array sheet corresponds to one LED bead.

[0008] Furthermore, a busbar is connected to the end of the MO back electrode, and a silicone weather-resistant sealant is provided on one side of the busbar.

[0009] Furthermore, one end of the silicone weather-resistant sealant is fixed to a substrate glass, and an aluminum alloy wire protection plate is connected to the outside of the silicone weather-resistant sealant.

[0010] Furthermore, an aluminum alloy frame is installed on the top of the aluminum alloy wire guard plate, and an aluminum alloy cover plate is snapped into the inner side of the aluminum alloy frame.

[0011] Furthermore, a glass pad is provided at the bottom outer end of the aluminum alloy frame, and a double-sided adhesive strip is adhered to the bottom of the aluminum alloy frame, with an EPDM adhesive strip on one side of the double-sided adhesive strip.

[0012] Furthermore, electronic components are housed inside the aluminum alloy frame, and one end of each electronic component is connected to a power source.

[0013] Furthermore, the power supply is fixedly connected to the aluminum alloy frame by bolts, and the aluminum alloy frame is tightly fitted with the EPDM adhesive strip.

[0014] This utility model provides a tempered laminated LED photovoltaic glass, which has the following beneficial effects:

[0015] 1. This utility model uses a microlens array to diffuse the light emitted by the LED beads when they emit light, as the microlens array corresponds one-to-one with each LED bead. This increases the illumination range of the LED beads, makes the light distribution of multiple LED beads more uniform, reduces dark areas, and improves the comfort of viewers.

[0016] 2. This utility model, through the application of silicone weather-resistant sealant, can seal the tempered conductive glass and the substrate glass, thereby preventing moisture and dust from seeping in and protecting the internal circuitry. At the same time, its corrosion resistance helps extend the service life of the tempered laminated LED photovoltaic glass. Furthermore, EPDM adhesive strips can be used to buffer the aluminum alloy frame and the substrate glass, preventing damage to the glass due to mechanical vibration caused by rigid contact, thus improving the overall protective performance.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3 As shown, a tempered laminated LED photovoltaic glass includes tempered conductive glass 1 and a microlens array 4. An ITO conductive layer 2 is disposed on the top of the tempered conductive glass 1, and LED beads 3 are embedded within the ITO conductive layer 2. The microlens array 4 is disposed inside the tempered conductive glass 1, arranged in a row around the top of the tempered conductive glass 1, with each microlens array 4 corresponding to one LED bead 3. Therefore, when the LED bead 3 emits light, the microlens array 4 can diffuse the light emitted by the LED bead 3, thereby improving the LED's performance. The illumination range of the LED beads 3 makes the light distribution of multiple LED beads 3 more uniform. A PVB film 5 is provided on one side of the ITO conductive layer 2, and a front electrode layer 6 is connected to one side of the PVB film 5. The PVB film 5 is used to provide mechanical strength and anti-shatter function. The front electrode layer 6 collects photocurrent and transmits it to the external circuit, while maximizing light transmittance. A high-resistivity layer 7 is provided on one side of the front electrode layer 6, and a buffer layer 8 is connected to one side of the high-resistivity layer 7. A CIGS layer 9 is provided on one side of the buffer layer 8, and an MO back electrode 10 is connected to one side of the CIGS layer 9.

[0023] like Figure 2 and Figure 3As shown, a busbar 11 is connected to the end of the MO back electrode 10, and a silicone weather-resistant sealant 12 is provided on one side of the busbar 11. The silicone weather-resistant sealant 12 seals the tempered conductive glass 1 and the substrate glass 13, thereby preventing moisture and dust from penetrating and protecting the internal circuit. One end of the silicone weather-resistant sealant 12 is fixed to the substrate glass 13, and an aluminum alloy wire protection plate 14 is connected to the outside of the silicone weather-resistant sealant 12. The tempered conductive glass 1 and the substrate glass 13 are used to protect the interior and improve the overall strength. An aluminum alloy frame 15 is installed on the top of the aluminum alloy wire protection plate 14, and an aluminum alloy cover is snapped into the inner side of the aluminum alloy frame 15. A glass pad 17 is provided at the bottom outer end of the plate 16 and the aluminum alloy frame 15. A double-sided adhesive strip 18 is adhered to the bottom of the aluminum alloy frame 15, and an EPDM adhesive strip 19 is provided on one side of the double-sided adhesive strip 18. An electronic component 20 is placed inside the aluminum alloy frame 15, and one end of the electronic component 20 is connected to a power supply 21. The power supply 21 is fixedly connected to the aluminum alloy frame 15 by bolts. The aluminum alloy frame 15 and the EPDM adhesive strip 19 are tightly attached. The EPDM adhesive strip 19 is used to buffer the aluminum alloy frame 15 and the substrate glass 13, so as to avoid the glass being easily damaged by mechanical vibration due to rigid contact, which helps to improve the overall protective performance.

[0024] In summary, when using this tempered laminated LED photovoltaic glass, firstly, according to... Figure 1 , Figure 2 and Figure 3 The structure shown utilizes tempered conductive glass 1 and substrate glass 13 for internal protection during use, enhancing overall strength. PVB film 5 provides mechanical strength and shatter resistance. During daytime use, photovoltaic power generation is achieved through the front electrode layer 6, high-resistivity layer 7, buffer layer 8, CIGS layer 9, and MO back electrode 10. Current is then transmitted to the power supply 21 for storage via busbar 11. At night, it powers the LED beads 3. Since the microlens array 4 corresponds one-to-one with the LED beads 3, when the LED beads 3 emit light, the microlens array 4 can be used to illuminate the LEDs. The light emitted by LED beads 3 is diffused, thereby increasing the illumination range of LED beads 3 and making the light distribution of multiple LED beads 3 more uniform, reducing dark areas and improving the comfort of viewers. Finally, the tempered conductive glass 1 and the substrate glass 13 can be sealed with silicone weather-resistant sealant 12 to prevent moisture and dust from seeping in, protecting the internal circuit. At the same time, its corrosion resistance helps to extend the service life of tempered laminated LED photovoltaic glass. Furthermore, EPDM adhesive strip 19 can be used to buffer the aluminum alloy frame 15 and the substrate glass 13, preventing the glass from being easily damaged by mechanical vibration due to rigid contact.
