Patent ID: 7674015

Claim:
A LED projector light module, comprising: a main body made of metallic material of good thermal conductivity and having an accommodation space located at a top of the main body, said accommodation space having a tapering bottom which is in the shape of either a sphere or a rounded cone; at least an LED unit configured inside a top end of the accommodation space of main body; a heat-radiating unit disposed at an outer rim of the main body where the heat generated by the LED unit can be effectively transferred to the heat-radiating unit through the main body; said heat-radiating unit being a heat-radiating fin set made of a plurality of L-shaped heat-radiating fins connected in tandem, short sides of the L-shaped heat-radiating fins being disposed with edgefolds in contact with and secured to the outer rim of the main body to increase a contact surface area, and long sides of the heat-radiating fin set radiating outwardly, wherein the short side of each L-shaped heat-radiating fin adjacent to the main body is disposed respectively with the edgefolds extending in three different directions, including a top edgefold, a bottom edgefold and a side edgefold, the side edgefolds substantially forming a surface area to produce a planar contact with the outer rim of the main body, the top edgefold and the bottom edgefold each have respectively a fixation hole thereon, and correspondingly, a fixed end is disposed respectively on outer edge extensions of the top edgefold and the bottom edgefold; a base connectable to the main body and having an electrically conductive pin at its bottom to match a projector socket, the bottom edgefolds of the L-shaped heat-radiating fins being in contact with the base; and a voltage conversion unit disposed inside the base that is electrically connected to the LED unit and to one end of the electrically conductive pin respectively.
