PURPOSE: A light source module is provided to reduce movement distance of heat generated in a light emitting device by a groove, thereby increasing a heat radiation property. CONSTITUTION: A light source module includes a heat radiation member(210), a circuit board(220), and a light emitting device(100). The circuit board is arranged on the heat radiation member and includes a penetration hole(221). The light emitting device is mounted on an area of the heat radiation member corresponding to the penetration hole. The heat radiation member includes a groove of predetermined depth within the area corresponding to the penetration hole. The light emitting device is arranged in the groove. |
