Patent ID: 7520647

Claim:
A light source device for a vehicle lamp, comprising: a base board; a plurality of chip mounting portions located adjacent the base board and configured in a line, the line extending in a first direction and having a central divider axis that is perpendicular to the first direction and divides the line into substantially equal halves; a plurality of electrodes located adjacent the plurality of chip mounting portions and extending along the first direction of the line and spaced from the central divider axis; a reflector located adjacent the base board and configured to form a cavity with a substantially rectangular opening that encloses and exposes both the plurality of chip mounting portions and the plurality of electrodes, wherein a central portion of the cavity is located at the central divider axis; a plurality of semiconductor light emitting chips mounted on the plurality of chip mounting portions, wherein an adjacent pair of the semiconductor light emitting chips are located at the central divider axis, and at least one electrode of the adjacent semiconductor light emitting chips is electrically connected to at least one of the plurality of electrodes; and an encapsulating resin disposed in the cavity.
