ABSTRACT:
An LED array in which the optical output distribution in each light emitting region is as uniform as possible. An n electrode 3 is provided on the under surface of a substrate 2 and a p electrode is provided on the upper surface thereof. A multiplicity of light emitting regions 4 are formed on the upper layer of the substrate 2. Two strip-like conductor portions 6c extending over each light emitting region 4 in ohmic contact are connected to each electrode 6 so that a current is efficiently applied to the conductor portions 6c of each light emitting region 4 and the optical output distribution in each light emitting region 4 is made uniform.
