Patent ID: 11815252

Abstract:
A light-emitting device, including a shell assembly and a heat dissipation assembly. The heat dissipation assembly includes a first heat dissipation portion and a second heat dissipation portion. The first heat dissipation portion is connected with the second heat dissipation portion. The first heat dissipation portion is used to load a light source assembly, and a cavity space is formed when the second heat dissipation portion is covered by and communicated with the shell assembly. The second heat dissipation portion is provided with a first through-hole portion, and the shell assembly is provided with a second through-hole portion, the first through-hole portion and the second through-hole portion circulate a cooling medium to remove heat from the cavity space. Whether the light-emitting device is installed vertically, horizontally or at a certain inclination, a good heat dissipation effect can be achieved and the applicable scope can be greatly expanded.
