Patent ID: 8847254

Claim:
A light emitting device, comprising: at least one light emitting diode capable of producing light in a first wavelength region, the at least one light emitting diode comprising a plurality of light emitting cells connected to one another in series on a single growth substrate; and a phosphor comprising a compound which includes copper and an alkaline earth metal as host lattice components and is activated by at least one rare earth element, said phosphor being positioned around the light emitting diode so as to absorb a portion of the light emitted from the light emitting diode and to emit light different in wavelength from the absorbed light, wherein the plurality of light emitting cells connected in series are arranged inside a rectifying bridge for applying rectified power to the plurality of light emitting cells, the rectifying bridge being arranged on the single growth substrate together with the light emitting cells, and wherein each light emitting cell comprises an n-type semiconductor layer, an active layer disposed on the n-type semiconductor layer, and a p-type semiconductor layer disposed on the active layer, and the n-type semiconductor layer, the active layer, and the p-type semiconductor layer comprise crystals grown on the single growth substrate.
