First Claim
Patent Images
1. A method of manufacturing an illumination apparatus whose primary purpose is illumination as opposed to display, the method comprising:
- (i) providing a light emitting element array, the light emitting element array comprising a plurality of light emitting elements arrayed on a first side of a first substrate, and the step of providing the light emitting element array comprising forming the plurality of light emitting elements and thereafter positioning them in an array on the first side of the first substrate; and
(ii) reducing the thickness of the light emitting element array by reducing the thickness of the first substrate by removing material from the direction of the second side of the first substrate.

Abstract
A light emitting element array for an illumination apparatus, an illumination apparatus and method of manufacture of the same in which an array of light-emitting elements and an array of light directing optics are provided between first and second attached mothersheet substrates wherein the thermal resistance of at least one of the mothersheet substrates is reduced by means of thickness reduction so as to provide reduced LED junction temperature.

19. An illumination apparatus whose primary purpose is illumination as opposed to display, the illumination apparatus comprising:
-
a light emitting element array; and the light emitting element array comprising a plurality of light emitting elements arrayed on a first substrate, the light emitting elements having been arrayed on the first substrate after the light emitting elements were formed; wherein the substrate is of reduced thickness compared to what its thickness was when the plurality of light emitting elements were arrayed on the first substrate. - View Dependent Claims (20, 21, 22)
