In some embodiments, the seal may be a finished seal ring, such as a rubber ring or the like. However, in the embodiment, the sealing element is a sealing rubber ring formed by solidifying liquid sealing glue; specifically, the second annular groove 31 is a glue injection groove, sealing glue is injected into the glue injection groove, and a sealing member is formed after the sealing glue is solidified. It is easy to understand that after the glue injection groove and the annular convex rib 22 are matched in place, the sealing glue flows into the first annular groove 21 of the lens 2 to form a sealing effect, and a good waterproof effect is further achieved. As can be seen from the description of the paragraph, the types of the sealing members are various, which is beneficial to enriching the diversity of the lamp module.

As shown in fig. 3, in order to facilitate glue overflow, the inner side edge of the inner slot 211 is lower than the outer side edge of the outer slot 212, specifically, the inner side edge of the inner slot 211 abuts against the heat sink 3, and a gap 6 is formed between the outer side edge of the outer slot 212 and the heat sink 3.
