Abstract
A heat conductive device for an LED has a heat sink and an LED carrier tightly fitted in the heat sink. The LED carrier has a mounting portion formed on one end thereof and having a first heat-conducting surface formed on a top of the mounting portion, and a heat-conducting portion formed along a perimeter of the mounting portion and having a second heat-conducting surface formed on the periphery of the heat-conducting portion. The first and second heat-conducting surfaces contact the engagement portion of the heat sink so that heat generated by LED operation is conducted to the heat sink through the heat-conducting portion, the first heat-conducting surface and the second heat-conducting surface. With the second heat-conducting surface of the LED carrier, heat can be more efficiently conducted to the heat sink and LEDs can be operated at an adequate operating temperature to prolong their life duration.
