The lamp housing 1 includes a U-shaped housing 11 and a light guide plate 12 integrally formed on the symmetrical edges of the bottom of the U-shaped housing and inclined outward. A lamp board mounting groove 13 with a T-shaped cross-section is provided on the bottom wall of the U-shaped housing. A connecting plate 14 is integrally formed on the outer wall of the U-shaped housing and the bottom edge of the light guide plate. A heat dissipation cavity 4 is formed between the outer wall of the U-shaped housing, the connecting plate, and the light guide plate. In this embodiment, the lamp housing is an aluminum structure, which is beneficial to improving heat conduction and heat dissipation performance. The PCB lamp board is a conventional structure in the prior art. During installation, the PCB lamp board is inserted into the lamp board mounting groove, which improves the convenience and effectiveness of assembly.

[0029] The symmetrical outer wall of the U-shaped housing is provided with C-shaped threaded post 5; the inner side of the end cap is provided with a screw 6 and a guide protrusion 7; during installation, the guide protrusion on the end cap is attached to the bottom wall of the U-shaped housing, and the screw is threaded into the C-shaped threaded post. This structure prevents the end cap from tilting or shifting during assembly, improving the stability and reliability of the assembly, and also enhancing the ease of installation.

[0030] The PCB lamp board has conductive wires 8 soldered to both ends; the inner side of the end cover has an integrally formed n-shaped protrusion 9; during installation, the end cover is snapped into the lamp housing, and the conductive wires are located within the n-shaped protrusion. This prevents damage to the conductive wires.

[0031] The end cap is integrally formed with mounting lugs 10 featuring mounting holes. The entire structure can be installed at the corresponding mounting location, such as a wall. To improve the sealing of the installation, a potting sealant layer is provided at the connection between the end cap and the lamp housing, and at the connection between the end cap and the lens panel.

[0032] The bottom edge of the inner side of the end cap is integrally formed with a protruding plate 15; the protruding plate and the bottom edge of the light guide plate are on the same plane; the encapsulated sealing layer of the protruding plate and the lens panel is located between the protruding plate and the bottom wall of the U-shaped shell.

[0033] This utility model has positive effects: its structure is reasonably designed, and the outwardly inclined light guide plate on the bottom edge of the U-shaped shell, together with the lamp board mounting groove, can effectively and quickly realize the installation and positioning of the PCB lamp board, and at the same time help to improve the lighting range. It also has a heat dissipation cavity, which helps to improve the overall heat dissipation performance. In addition, it has C-shaped screw hole posts that work with the screws and guide protrusions on the end cover, which helps to quickly realize the disassembly and positioning of the end cover and the lamp shell, and improves the convenience and stability of assembly. It has strong applicability and good practicality.

[0034] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here.
