Abstract:
1. A semiconductor light emitting device comprising: a substrate; a semiconductor lamination portion formed on the substrate by laminating semiconductor layers so as to form a light emitting layer; a plurality of light emitting units each formed in electrically separate portions of the semiconductor lamination portion, each of the plurality of light emitting units having a pair of electrodes which are each connected to a conductivity type layer of the semiconductor lamination portion, at least two of the plurality of light emitting units being connected in series between a pair of electrode pads, the electrode pads being connected to an external electric source; wiring films which are each connected to at least one of the electrodes, wherein the wiring films connect each of the plurality of light emitting units in series and/or parallel; an inductor shaped as a coil having plural loops, for absorbing surges, the inductor being connected between and in series with the at least two of the plurality of light emitting units; a dummy region which does not contribute to light emitting is formed between the separation groove and a light emitting unit of one side of the separation groove, the inductor is formed within the dummy region, the inductor has an inductance of approximately 1 to 10 nH, and the inductor protects one or more of the plurality of light emitting units from an electrical surge that would otherwise damage the one or more light emitting units.
