[0018] When working, the design of the mounting mechanism uses the separation type of aluminum cup 3, and the structure of plastic-coated aluminum is formed by subsequent processing and assembly. The components include plastic shell 4, aluminum cup 3, and aluminum cover 2. The aluminum cup 3 is placed inside the plastic shell 4, and a certain structure is reserved between them for gluing. The circuit board 20 is assembled inside the aluminum cup 3, and the aluminum cover 2 is placed on top. The lamp panel 1 is attached to the aluminum cover 2 through heat-conducting glue 7. The process of the entire ball bubble lamp is as follows: first, place the aluminum cup 3 correctly in the plastic shell 4. Second, pour heat-conducting glue 7 into the structure space between the plastic shell 4 and the aluminum cup 3, so that they are in full contact with the inner aluminum cup 3 and the outer plastic shell 4, playing the role of heat conduction and adhesion installation. Let the plastic shell 4 and the aluminum cup 3 with glue stand still, waiting for the heat-conducting glue 7 to dry completely. Assemble the circuit board 20, and finally cover the aluminum cover 2 with the glued lamp panel 1, completing the entire ball bubble lamp lamp cup.
