Patent ID: 8581279

Claim:
A luminescence diode chip having: a radiation exit area, and a contact structure which is arranged on the radiation exit area and comprises a bonding pad and a plurality of contact webs, wherein the contact webs are provided for current expansion and are electrically conductively connected to the bonding pad, wherein the bonding pad is arranged in an edge region of the radiation exit area, wherein each contact web of the contact webs has a longitudinal direction and a width in a direction perpendicular the longitudinal direction of the each contact web and parallel to a plane of the radiation exit area, wherein a first contact web of the contact webs has a width that varies along the longitudinal direction thereof and contains a plurality of partial regions having a different width, and wherein at least one of the partial regions of the first contact web is located at a greater distance from the bonding pad and is wider than one of the partial regions of the first contact web located at a shorter distance from the bonding pad.
