Therefore, the number of the light sources 3 in the present comparative embodiment must be consistent with N, and the positions of the light sources 3 on the housing 2 are limited by the positions of the through holes, so that each waterproof connector 14 is very close to the light source 3, and the heat of the light source 3 is conducted to the waterproof connector 14, which may cause excessive deformation of the waterproof connector 14. In this comparative example, the number of the waterproof joints 14 is large, and as long as one waterproof joint 14 is excessively deformed, the protection level of the whole modular lamp is reduced.
