Patent ID: 8207543

Claim:
A light source comprising a substrate; a light emitting structure comprising: a first layer of semiconductor material of a first conductivity type deposited on said substrate; an active layer overlying said first layer; and a second layer of semiconductor material of an opposite conductivity type from said first conductivity type overlying said active layer; a transparent conducting layer overlying said second layer of semiconductor material; a barrier that divides said light emitting structure into first and second segments that are electrically isolated from one another; a serial connection electrode that connects said first layer in said first segment to said transparent conducting layer in said second segment; an insulating layer between said second layer and said transparent conducting layer in said second segment, said insulating layer underlying said serial connection electrode such that current flowing from said serial connection electrode is blocked by said insulating layer in a region underlying said serial connection electrode; a first power contact electrically connected to said second layer in said first segment; and a second power contact electrically connected to said first layer in said second segment, wherein said first and second segments generate light when a potential difference is created between said first and second power contacts.
