LED array capable of reducing uneven brightness distribution

摘要

ABSTRACT OF THE DISCLOSURE A semiconductor LED array (100) comprises a plurality of semiconductor LED elements (101a, 101b) disposed on an oblong substrate that is long in a first direction (W) and arranged along with said first direction (W). Each LED element comprises an electrode layer (12) formed on the substrate (30), a semiconductor LED stack (2) formed on the electrode layer, stretched long in the first direction and comprising a p-type semiconductor layer (23), an active layer (22) and an n-type semiconductor layer (21), a first wiring layer (11) formed along and in parallel to one long side of the semiconductor LED stack, and second wiring layers (8) extending to a direction of a short side (H) from the first wiring layer and electrically connected to the n-type semiconductor layer (21) on a surface of the semiconductor LED stack. The first wiring layers are disposed on different long sides of the semiconductor LED stacks (2) in the adjacent LED elements.
