Abstract
A light emitting device includes a light emitting element having at least two electrodes disposed at the side of the light output surface thereof; and a base member having a recess and lead portions corresponding to the electrodes, the light emitting element being mounted on the base member and received in the recess, wherein the light output surface faces toward opening of the recess that becomes smaller while approaching the light output surface, and the electrodes are respectively in electrical connection with the lead portions that extend from the connection positions to outer edge of the base member for power connection, and a light reflecting portion is disposed in the recess adjacent to the light output surface such that the light emitted from the light emitting element can be reflected to walls of the recess to form a substantially collimated light beam so as to improve light efficiency.
