Abstract

A light source module includes a first light source, a second light source, a third light source, and a first heat sink. The first heat sink includes a first base and a number of first fins. A bottom surface of the first base is attached to the first light source and the second light source. The first fins perpendicularly extend from a top surface of the first base away from the first light source and the second light source. Each first fin includes a first fin portion adjacent to the first light source and a second fin portion adjacent to the second light source, and defines a first slot for increasing the thermal resistance between the first fin portion and the second fin portion.
