Abstract
Abstract Light Emitting Diode (LED) arrays are made by first applying LED monoliths to a metallic palate, such as a copper palate, and then securing the palates 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 palates.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
63 words
A method of producing a light emitting diode (LED) array, the steps comprise: placing an adhesive upon a metallic palate, placing a monolith composed of a ceramic member having a plurality of LED sites thereon upon the metallic palate so that adhesive is therebetween, curing the adhesive and - securing a plurality of metallic palates with LED monoliths thereon end-to-end upon a substrate.
Claim 2
Independent Claim
63 words
A method of producing a light emitting diode (LED) array, the steps comprise: placing an adhesive upon a metallic palate, placing a monolith composed of a ceramic member having a plurality of LED sites thereon upon the metallic palate so that adhesive is therebetween, curing the adhesive and - securing a plurality of metallic palates 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
85 words
A method of producing a light emitting diode (LED) array, the steps comprising: placing an adhesive upon the metallic slab at a plurality of locations, placing a monolith comprising a ceramic member having a plurality of LED sites upon the metallic slab at each adhesive location, curing the adhesive, cutting the metallic slab so as to segregate each monolitn to thereby form a plurality of palates and with a monolith thereon, and securing a plurality of metallic palates with monoliths thereon end-to-end upon a substrate.
Claim 5
Independent Claim
85 words
A method of producing a light emitting diode (LED) array, the steps comprising: placing an adhesive upon the metallic slab at a plurality of locations, placing a monolith comprising a ceramic member having a plurality of LED sites upon the metallic slab at each adhesive location, curing the adhesive, cutting the metallic slab so as to segregate each monolitn to thereby form a plurality of palates and with a monolith thereon, and securing a plurality of metallic palates 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.
Claim 8
Dependent Claim
35 words
A light emitting diode (LED) array, comprising: a substrate; a plurality of metal palates secured to the substrate and a monolith having a plurality of LED sites thereon secured to each of the metal palates.
Claim 9
Dependent Claim
35 words
A light emitting diode (LED) array, comprising: a substrate; a plurality of metal palates secured to the substrate and a monolith having a plurality of LED sites thereon secured to each of the metal palates.
Claim 10
Dependent Claim
15 words
The array of claim 6 wherein said monoliths are longitudinally placed end-to-end on said substrate.
Claim 11
Dependent Claim
11 words
The array of claim 6 wherein said metal palates are copper.
