Abstract:
1. A light source module comprising: a circuit board having a surface on which a semiconductor light emitting device is mounted, wherein the circuit board is adapted to be placed on a mounting base of a light source holding member, and a power feeding attachment to supply power to the semiconductor light emitting device, wherein the circuit board comprises: a board part on which the semiconductor light emitting device is mounted; and a conductive circuit formed on the surface of the board part, the conductive circuit including a pair of terminal parts and a light source connecting part to connect the pair of terminal parts and the semiconductor light emitting device, wherein the power feeding attachment comprises: an electrically-insulating portion formed of an electrically-insulating material having a thermal conductivity of 5.0 to 10.0 W/m·K; and a conductive portion formed of a conductive material and embedded in the electrically-insulating portion except a portion thereof, and wherein the power feeding attachment is adapted to be attached to the light source holding member such that the electrically-insulating portion presses at least a portion of the circuit board against the mounting base.
