Abstract
Abstract A plurality of individual raised metal contact areas are distributed over and attached to a surface of a semiconductor light conversion element such as a gallium phosphide lightemitting diode. The outer tips of at least some of the raised contact areas are bonded to an electrical contact member, thereby providing an air boundary over a substantial portion of said semiconductor surface and thus causing considerable internal light reflection.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
A contact construction for attaching a solid state light conversion element to a conductor member, comprising a plurality of individual raised electrical contact areas distributed over and attached to a surface of said light conversion element, said element being positioned with said surface adjacent to a surface of said conductor member, and bonding means attaching the outer tips of at least some of said raised contact areas to said surface of the conductor member and providing electrical connection therebetween, a major portion of said surface of the light conversion element being free from contact with solid matter.
Claim 2
Dependent Claim
97 words
A contact construction for attaching a solid state light conversion element to a conductor member, comprising a plurality of individual raised electrical contact areas distributed over and attached to a surface of said light conversion element, said element being positioned with said surface adjacent to a surface of said conductor member, and bonding means attaching the outer tips of at least some of said raised contact areas to said surface of the conductor member and providing electrical connection therebetween, a major portion of said surface of the light conversion element being free from contact with solid matter.
Claim 3
Dependent Claim
97 words
A contact construction for attaching a solid state light conversion element to a conductor member, comprising a plurality of individual raised electrical contact areas distributed over and attached to a surface of said light conversion element, said element being positioned with said surface adjacent to a surface of said conductor member, and bonding means attaching the outer tips of at least some of said raised contact areas to said surface of the conductor member and providing electrical connection therebetween, a major portion of said surface of the light conversion element being free from contact with solid matter.
Claim 4
Dependent Claim
97 words
A contact construction for attaching a solid state light conversion element to a conductor member, comprising a plurality of individual raised electrical contact areas distributed over and attached to a surface of said light conversion element, said element being positioned with said surface adjacent to a surface of said conductor member, and bonding means attaching the outer tips of at least some of said raised contact areas to said surface of the conductor member and providing electrical connection therebetween, a major portion of said surface of the light conversion element being free from contact with solid matter.
Claim 5
Dependent Claim
36 words
A construction as claimed in claim 1 in which said bonding means comprises said outer tips of at least some of the raised contact areas being in melted contact with said surface of the conductor member.
Claim 6
Dependent Claim
33 words
A construction as claimed in claim 2 in which said light conversion element comprises gallium phosphide, said raised contact areas comprise a gold-germanium eutectic, and said surface of the conductor member comprises gold.
