[0002] In the field of building integrated circuits, photovoltaic (PV) panels are increasingly widely used. They not only convert solar energy into electricity, providing clean energy for buildings, but also integrate with the building's exterior, enhancing its aesthetics and technological appeal. Meanwhile, with the increasing demand for nighttime lighting in buildings, integrating light strips into buildings has become a common decorative and functional design.

See patent document with application number 202322404102.7, which discloses a photovoltaic panel including a panel layer, an adhesive layer and a PCB base plate arranged sequentially from top to bottom. The battery cells are welded on the PCB base plate. The panel layer, adhesive layer and PCB base plate are laminated and bonded together by a laminator. The panel layer is provided with a number of protrusions. The protrusions are integrally formed with the panel layer and are pressed by a laminator. The center of the protrusion is raised and its edge is smooth. A groove is provided between adjacent protrusions and the groove is inclined. The groove is connected to the edge of the panel layer.

[0030] The technical solution of this utility model will be further explained and described below with reference to the accompanying drawings and embodiments, but this utility model is not limited to the embodiments described below.

[0031] In the field of building integration, when it is necessary to install light strip 7 on photovoltaic panels, it is usually necessary to first install and fix the photovoltaic panels, and then install the light strip 7 separately on the photovoltaic panels. The installation process of light strip 7 is cumbersome, resulting in low installation efficiency of the overall structure formed by photovoltaic panels and light strip 7.

[0032] Firstly, referring to Figure 1 and Figure 2 This invention illustrates a photovoltaic module capable of being illuminated, comprising a photovoltaic multilayer panel, a subframe 4, and a lighting assembly.

By using the first layer 1 and the second layer 2 to form the receiving space 3, and fixing the lighting component to the subframe 4 with the lighting component partially located within the receiving space 3, the light trough frame 6 is hidden from the photovoltaic module's appearance, improving electrical safety and the aesthetics of the photovoltaic module.

[0035] Specifically, the second plate layer 2 can be spaced with one, two, three or four side end faces to form a receiving space 3 between itself and the side end face of the first plate layer 1. The receiving space 3 can be set according to the actual number and position of the light strips 7.

[0036] Specifically, the second plate layer 2 and the subframe 4 are connected by a connector 9. The connector 9 can be a sealing strip, a sealing gasket, or a rubber block.

[0038] Optionally, the end face of the lamp trough frame 6 is flush with the side end face of the first plate layer 1; when the end of the photovoltaic module with the lamp trough frame 6 is connected to the adjacent photovoltaic module, it is convenient to fill the sealing structure such as sealant and sealing strip, and improve the sealing effect between adjacent photovoltaic modules.

[0039] Optionally, a gap is provided between the light trough frame 6 and the second plate layer 2, so that a buffer is formed between the light trough frame 6 and the second plate layer 2, thereby mitigating the direct impact force of external impact on the second plate layer 2 and preventing damage to the second plate layer 2.

[0040] Optionally, the area of ​​the first plate layer 1 corresponding to the accommodating space 3 is a light-transmitting area, so that the light strip 7 can transmit illumination light through the transparent first plate layer 1.

[0043] Specifically, the light trough frame 6 is snapped into the light-transmitting cover plate 5. The end of the light-transmitting cover plate 5 near the subframe 4 is provided with an inverted "L"-shaped snap-fit ​​block. The side wall of the open end of the light trough frame 6 is provided with an "L"-shaped slot that matches the snap-fit ​​block.

[0044] Optionally, the connection between the light trough frame 6 and the light-transmitting cover plate 5 can be a screw connection, an adhesive connection, or a snap-fit ​​connection. The connection method between the light trough frame 6 and the light-transmitting cover plate 5 can be selected according to the actual use requirements, ensuring that the connection between the light trough frame 6 and the light-transmitting cover plate 5 is firm and meets the use requirements.

[0045] Optionally, the light trough frame 6 is tightly attached to the side end face of the photovoltaic multilayer panel to achieve a seal between the light trough frame 6 and the photovoltaic multilayer panel, preventing moisture, dust, etc. from entering the photovoltaic multilayer panel, thereby extending the service life of the photovoltaic multilayer panel.
