Heat dissipating apparatus for automotive LED lamp
First Claim
1. A heat dissipating apparatus for automotive LED lamp, fixed to an automobile body, and electrically connected to an automotive LED lamp driving circuit in the automobile body, and the automotive LED lamp comprising:
- an automotive lamp set having a base and a lamp housing which is a light transmitting body fixed at a front of the base;
a heat dissipating module connected to the base of the automotive lamp set and having a plurality of fins so as to form an insulation circuit in the heat dissipating module, such that the insulation circuit is not electrically connected with a body of the heat dissipating module;
a plurality of LEDs electrically connected to the insulation circuit of the heat dissipating module and each the LED having a main base, the main base having a metal conducting plate so as to conduct heat energy produced by the LEDs to the heat dissipating module; and
a reflecting unit installed inside the base of the automotive lamp set and fixed to the bottom of the reflecting unit so as to reflect a light projected from the LEDs and refracting the light towards the lamp housing.

Abstract
In a heat dissipating apparatus for an automotive LED lamp, the automotive LED lamp includes an automotive lamp set, a heat dissipating module, a plurality of LEDs, and a reflecting unit. The heat dissipating module is wrapped to form an insulation circuit for separating heat energy and electric power of the insulation circuit and heat dissipating module. The LED is electrically connected to the insulation circuit, and a main base of the LED installs a metal conducting plate for conducting the heat produced by the LED to the heat dissipating module. The reflecting unit is installed in the automotive lamp set, so that the heat dissipating module can use a cold air or a liquid coolant as the heat dissipating medium for dissipating heat, preventing a drop of light output caused by an overheat, and avoiding damages to the LED to extend the life expectancy of the automotive LED lamp.
