Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b): referring to fig. 1-3, a waterproof heat sink assembly for LED comprises a heat sink base plate, a plurality of parallel heat sinks perpendicular to the inner side of the heat sink base plate, and a light emitting panel 1 attached to the outer side of the heat sink base plate; the heat dissipation base plate and the light emitting panel 1 are provided with a plurality of first preset holes 2 penetrating through the heat dissipation base plate and the light emitting panel 1, a potential hole 3 is formed between two heat dissipation fins, and the heat dissipation fins comprise first heat dissipation fins 4 arranged at two ends, second heat dissipation fins 5 close to the first preset holes 2, third heat dissipation fins 6 close to the potential holes 3 and fourth heat dissipation fins 7; the joint of the first preset hole 2 and the second radiating fins 5 is provided with a convex strip 8 for burying the first preset hole 2, and a connecting block 9 for burying a waterproof joint is arranged between the third radiating fins 6.
In this embodiment, the first preset holes 2 are formed in the heat dissipation bottom plate and the light emitting panel 1, so that the light emitting panel 1 can be well fixed on the heat dissipation bottom plate, and heat dissipation is facilitated; a convex strip 8 is arranged at the joint of the first preset hole 2 and the second radiating fin 5 to bury the first preset hole 2, so that external liquid or dust can be prevented from entering the light-emitting panel 1 through the first preset hole 2 to damage the light-emitting body; the third heat dissipation fins 6 are provided with connecting blocks 9 therebetween, so that one ends of the waterproof joints can be fixed for locking the waterproof joints, and if the connecting blocks 9 are not provided, the waterproof joints can penetrate through the light emitting panel 1 to affect the light emitting performance and the appearance.
