Patent ID: 7750458

Claim:
A light source module used in a lighting device for vehicle and fitted into a radiator, comprising: a ceramic circuit board on which a predetermined conductive pattern is formed, a semiconductor light emitting element arranged on said ceramic circuit board and connected to the conductive pattern, and an attachment for power feeding bonded to the ceramic circuit board on which said semiconductor light emitting element is arranged, wherein said attachment for power feeding is provided with a power feeding part connected to an external power source, a plate-shaped part comprising an arrangement hole, the inner surface of the arrangement hole surrounding an outer circumferential surface of the ceramic circuit board, and a power feeding terminal formed in plate shape and protruded from the plate-shaped part to a side of the ceramic circuit board, wherein bottom surface of one end of the power feeding terminal is connected to a top surface of the conductive pattern, overlapping in a thickness direction, wherein the power feeding terminal of the attachment for power feeding is fixed and connected to the conductive pattern of the ceramic circuit board by welding, and wherein the ceramic circuit board and the plate-shaped part of the attachment for power feeding are formed in a substantially same thickness and the power feeding terminal is protruded from a side surface of the plate-shaped part located opposite to an outer circumferential surface of the ceramic circuit board.
