Abstract:
1. A light source module comprising: a circuit board on which a circuit pattern is formed, the circuit pattern comprising a first part and a second part; a semiconductor light emitting element comprising a first surface formed in an oblong shape, and a second surface positioned facing opposite the first surface, wherein the second surface is connected with the second part of the circuit pattern; an electrode pad provided on the first surface of the semiconductor light emitting element and comprising a connecting portion; and a connecting body connected with the connecting portion of the electrode pad and the first part of the circuit pattern, wherein the electrode pad is provided on a portion of the semiconductor light emitting element that includes one end portion of the first surface, wherein the connecting portion of the electrode pad is provided at a position in one of a continuous and spaced manner in a lengthwise direction of the electrode pad, and wherein a side edge extending in the lengthwise direction of the electrode pad is formed as a cut-off line forming portion that forms a cut-off line of a light distribution pattern generated by light emitted from the semiconductor light emitting element.
