Abstract
Abstract Light Emitting Diodes (LED) arrays are made by first applying LED monoliths to a metallic pallet, such as a copper pallet, and then securing the pallets to a substrate in a preferred geometrical arrangement. Because copper is so readily machinable, one is able to produce sizes as required for the geometry of an LED array and because of the rigidity, the problem of the fragile modules is removed since they are part of the pallets.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
65 words
A method of producing a light emitting diode (LED) array, the steps comprise: placing an adhesive upon a plurality of metallic pallets, placing a monolith composed of a semiconductor material and having a plurality of LED sites thereon upon each of the metallic pallets so that adhesive is therebetween, curing the adhesive and securing the metallic pallets with LED monoliths thereon end-to-end upon a substrate.
Claim 2
Independent Claim
65 words
A method of producing a light emitting diode (LED) array, the steps comprise: placing an adhesive upon a plurality of metallic pallets, placing a monolith composed of a semiconductor material and having a plurality of LED sites thereon upon each of the metallic pallets so that adhesive is therebetween, curing the adhesive and securing the metallic pallets with LED monoliths thereon end-to-end upon a substrate.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein the monoliths are formed of a longitudinally extending member and the monoliths are longitudinally aligned and secured in tandem.
Claim 4
Independent Claim
87 words
A method of producing a light emitting diode (LED) array, the steps comprising: placing and adhesive upon a metallic slab at a plurality of locations, placing a monolith comprising a semiconductor material and having a plurality of LED sites thereon upon the metallic slab at each adhesive location, curing the adhesive, cutting the metallic slab so as to segregate each monolith to thereby form a plurality of pallets, each with a monolith thereon, and securing a plurality of matallic pallets with monoliths thereon end-to-end upon a substrate.
Claim 5
Independent Claim
87 words
A method of producing a light emitting diode (LED) array, the steps comprising: placing and adhesive upon a metallic slab at a plurality of locations, placing a monolith comprising a semiconductor material and having a plurality of LED sites thereon upon the metallic slab at each adhesive location, curing the adhesive, cutting the metallic slab so as to segregate each monolith to thereby form a plurality of pallets, each with a monolith thereon, and securing a plurality of matallic pallets with monoliths thereon end-to-end upon a substrate.
Claim 6
Dependent Claim
25 words
The method of claim 3 wherein the monoliths are formed of a longitudinally extending member and the monoliths are longitudinally aligned and secured in tandem.
Claim 7
Dependent Claim
32 words
The method of claim 3 including the step of placing spacers between the monoliths as the monoliths are placed upon the metal slab and removing the spacers after the adhesive is cured.
