Abstract
A semiconductor light emitting device includes: a conductive substrate; a semiconductor light emitting layer which includes a first semiconductor layer formed on one surface of the conductive substrate and having a first conductivity type, and a second semiconductor layer formed on the first semiconductor layer and having a second conductivity type opposite to the first conductivity type; first light emitting spots which are alternately arranged around a periphery of the semiconductor light emitting layer and emitting light to an exterior from the semiconductor light emitting layer; second light emitting spots having surfaces intersecting with the first light emitting spots and emitting light at an amount smaller than an amount of light emitted via the first light emitting spots; and wirings arranged along the second light emitting spots and electrically short circuiting an area between the first light emitting layer and the surfaces of the conductive substrate.
