Patent ID: 8183761

Claim:
A light emitting apparatus having an optical axis extending in a light emitting direction of the light emitting apparatus comprising: a base having an upper surface and a rear surface; a first patterned electrode and a second patterned electrode each extending from the upper surface of the base to the rear surface thereof; a light emitting device electrically connected to the first patterned electrode at the upper surface of the base; a wiring portion connecting the light emitting device to the second patterned electrode; and a resin portion located adjacent the upper surface of the base, the resin portion configured to cover at least the light emitting device and the wiring portion, wherein: the first and second patterned electrodes are separated from each other on both sides at each of the upper surface and the rear surface of the base with a predetermined distance; the first and second patterned electrodes are configured such that a first ratio is a ratio of occupied area of the first and second patterned electrodes on the upper and rear surfaces of the base within a predetermined area, the predetermined area including an area of the upper surface and an area of the rear surface which coincide with the resin portion when viewed from along the optical axis of the light emitting apparatus, a second ratio is a ratio of occupied area of the first and second patterned electrodes on the upper and rear surfaces of the base within an adjacent area just outside of the predetermined area, the adjacent area being in contact with and extending from the predetermined area, the second ratio is smaller than the first ratio; the first patterned electrode and the second patterned electrode are separated from each other to form a space on the rear surface of the base; the space extends along and defines a substantially continually curving path in a width direction of the base; the continually curving path extends from and contacts a first side of the base and extends to and contacts a second side of the base opposed to the first side; and the first side and second side are spaced from each other in a direction that is normal to a longitudinal axis of the base.
