Abstract:
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; providing an optical array comprising a plurality of directional optical elements arrayed on a first side of a second substrate; (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; and before step (ii) is performed, forming a structure comprising the light emitting element array and the optical array, with the first side of the first substrate facing the first side of the second substrate, and with respective light emitting elements aligned with respective optical elements.
