AI Technical Summary
The independent circuitry of existing metal substrates for automotive lighting is connected to the metal substrate, resulting in short air circulation time, inefficient heat dissipation, and poor heat dissipation performance.
A heat sink is attached to the bottom of the metal substrate, and a heat-conducting plate and ventilation holes are set on the heat sink. The ventilation holes are fixed with staggered baffles to increase air flow resistance. Combined with the design of slider, locking block and return spring, the heat sink is easy to disassemble and install and is stably connected.
The heat dissipation of the metal substrate is improved and it is easy to disassemble and reassemble. The air absorption of high temperature is enhanced by the barrier plate, the movement of the slider facilitates the cleaning of the heat sink and quick disassembly and reassembly, and the locking block and return spring improve the connection stability.
