Patent ID: 8648373

Claim:
A semiconductor light emitting device, comprising: a case including: a base member formed of ceramic, the base member including a front surface and a rear surface; and wirings including: a front surface layer including an anode pad and a cathode pad which are formed at the front surface; a rear surface layer including an anode mounting electrode and a cathode mounting electrode which are formed at the rear surface; an anode through wiring electrically connecting the anode pad and the anode mounting electrode and passing through at least a portion of the base member in a thickness direction of the base member; and a cathode through wiring electrically connecting the cathode pad and the cathode mounting electrode and passing through at least a portion of the base member in the thickness direction of the base member; and an LED chip mounted on the case, the LED chip including: a substrate; an n-type semiconductor layer; a p-type semiconductor layer; an active layer disposed between the n-type semiconductor layer and the p-type semiconductor layer; an anode electrode electrically connected to the p-type semiconductor; and a cathode electrode electrically connected to the n-type semiconductor, the n-type semiconductor layer, the active layer, and the p-type semiconductor layer being stacked on the substrate, and the anode electrode and the cathode electrode facing the case when the LED chip is mounted on the case.
