Wherein the bottom shell 2 and the cover plate 4 are preferably made of metal materials, such as aluminum alloy, magnesium alloy and the like.

The bottom shell 2 is a thin frame structure, and is made of metal materials, and because materials such as aluminum alloy, magnesium alloy and the like have better strength, the required strength of the thin frame structure can be achieved, and compared with the bottom shell 2 made of PC materials, the thickness of the thin frame structure can be greatly reduced under the requirement of the same strength. The flatness of the bottom shell 2 needs to be ensured in the process of manufacturing the bottom shell 2, and the flatness and the dimension of the bottom shell 2 can be completely finished in the prior art. So that the assembly of the PCB lamp panel 1 on the bottom chassis 2 can ensure its accuracy. The cover plate 4 can be processed into a thin plate shape by aluminum alloy, magnesium alloy and the like, can be integrated with the bottom shell 2 through gluing and pressing, and can be sealed and waterproof at the joint of the cover plate and the bottom shell by using electronic pouring sealant.

Of course, the connection between the bottom shell 2 and the cover plate 4 is not limited to the gluing, but may be other existing forms such as screw connection or snap connection.

In the scheme, the bottom shell 2 adopts a metal thin frame structure, so that the thickness of the bottom shell can be effectively reduced while the strength is ensured, the weight of the bottom shell can be reduced by adopting the frame structure, meanwhile, the bottom shell and the cover plate 4 are both made of metal, the processing precision can be effectively improved, the coefficient of thermal expansion and contraction is reduced, the heat dissipation performance of the module can be improved, and the service life of the module is prolonged.

The bottom shell 2 comprises a rectangular outer frame 10 and connecting ribs 11 arranged inside the rectangular outer frame 10, the connecting ribs 11 are mutually connected into a whole, the connecting ribs 11 are connected with the rectangular outer frame 10, the PCB lamp panel 1 is fixed on the connecting ribs 11, and the cover plate 4 is also fixed on the connecting ribs 11.

The bottom shell 2 is composed of an outer frame and connecting ribs 11, the arrangement of the connecting ribs 11 can be set according to the actual connection position requirement of the PCB lamp panel 1, and the quantity of the connecting ribs 11 is reduced as much as possible under the condition of meeting the strength requirement and the installation requirement of the PCB lamp panel 1 so as to reduce the weight of the bottom shell 2 to the greatest extent. The frame structure formed by the outer frame and the connecting ribs 11 has better integrity and strength under the action of the connecting ribs 11.

The cover plate 4 is provided with a magnetic attraction buckle 6 in an array, and the magnetic attraction buckle 6 is used for fixing the module on the box body. After the magnetic attraction buckle 6 is fixed on the cover plate 4, when the module is assembled to the box body in the follow-up process, the module can be fixed only by directly attracting the module to the box body through the magnetic attraction buckle 6, and the installation of the module is greatly facilitated.
