Abstract:
1. A solid state lighting tile, comprising: a substrate; a plurality of lighting element clusters on a surface of the substrate, wherein respective ones of the plurality of lighting element clusters include first, second and third mounting positions configured to receive solid state light emitting devices; a plurality of first solid state light emitting devices configured to emit a first color light, a plurality of second solid state light emitting devices configured to emit a second color light, and a plurality of third solid state light emitting devices configured to emit a third color light, wherein respective ones of the first, second and third solid state light emitting devices are mounted in respective ones of the plurality of lighting element clusters so that respective ones of the lighting element clusters include a first solid state light emitting device, a second solid state light emitting device, and a third solid state light emitting device, wherein the plurality of lighting element clusters are provided in first and second lines of lighting element clusters including a first lighting element cluster in the first line of lighting element clusters and second and third lighting element clusters adjacent one another in the second line of lighting element clusters, the first, second and third neighboring lighting element clusters defining a triangular region therebetween; wherein the first solid state lighting devices in the first line of lighting element clusters are connected in a first series electrical connection to form a first string, the second solid state lighting devices in the first line of lighting element clusters are connected in a second series electrical connection to form a second string, and the third solid state lighting devices in the first line of lighting element clusters are connected in a third series electrical connection to form a third string; and wherein the lighting element clusters are configured such that the mounting positions of respective first, second and third light emitting devices in one of the first, second and third lighting element clusters are not repeated in others of the first, second and third lighting element clusters.
