Multi-colored light sources
First Claim
1. A light array comprising a plurality of coloured light-emitting diode elements arranged in a non-random pattern, the plurality of coloured light-emitting diode elements being dispersed within the array so as to provide a uniform colour output;
- wherein the plurality of coloured light-emitting diode elements comprises a plurality of red coloured light-emitting diode elements, a plurality of green coloured light-emitting diode elements, and a plurality of blue coloured light-emitting diode elements;
wherein the placement of each coloured light-emitting diode element is such that individual coloured light-emitting diode elements are dispersed over the whole surface of the array not following any regular vertical, horizontal or diagonal patterns, wherein the placement of each coloured light-emitting diode element is such that no diagonal, vertical or horizontal line of the array comprises only light-emitting diode elements of the same colour.

Abstract
Described herein is a light array for luminaires which comprises a plurality of coloured light-emitting diode (LED) elements that are arranged within the array to provide better uniformity of illumination. The light array may be rectangular and include equal numbers of colored LED elements of four colors. The red LED elements are grouped towards the center of the light array with the other colors dispersed throughout the array. Two or more light arrays can be placed adjacent one another to increase the illumination produced whilst maintaining the benefit of better uniformity of illumination.
