Heat dissipating structure for light bulb assembly, has light seat to install LED, where seat includes coupling part connected to coupling part of sleeve, so that support, heat-dissipation cover, and light seat are connected together

摘要

The structure has a support (10) including a sleeve (11) that defines a space for receiving a printed circuit board (14). The sleeve includes an abutment part (112) on a peripheral side, and a coupling part (111) on a lateral side. A cover (20) includes a heat dissipation through-hole (21) for introducing the sleeve, and cooling fins (22) around an outer peripheral side of the hole. A light seat (30) is provided to install an LED (40), where the seat includes a coupling part connected to the coupling part of the sleeve, so that the support, cover, and light seat are connected together.
