Abstract
A light source module includes a light source for emitting light, and a heat sink for absorbing heat from the light source and dissipating the heat to the outside. The heat sink includes a mounting part for attaching the light source, and a heat dissipation fin for absorbing heat generated by the light source and dissipating the heat to the outside. An electrical insulating layer is provided on at least one surface of the heat sink, and an electrically conductive layer is provided in the insulating layer. The electrically conductive layer provides a path through which electric current is applied to the light source. A lens cover is provided over the light source.
