Patent ID: 8123375

Claim:
A solid state lighting tile, comprising: a substrate having a planar surface; a first set of contact pads on a first end of the substrate and a second set of contact pads on a second end of the substrate, wherein the first set of contact pads comprises a first anode contact, a second cathode contact, a third anode contact and a fourth cathode contact, wherein the second set of contact pads comprises a first cathode contact, a second anode contact, a third cathode contact and a fourth anode contact, and wherein the first cathode contact and the second anode contact are between the third cathode contact and the fourth anode contact at the second end of the substrate; a first plurality of solid state light emitting devices (LEDs) on the substrate, wherein the first plurality of LEDs are connected in series to form a first string of LEDs of a first color, the first string coupled to the first anode contact at a first end of the substrate and coupled to the first cathode contact at a second end of the substrate; a second plurality of LEDs on the substrate, the second plurality of LEDs connected in series to form a second string of LEDs of the first color, the second string coupled to the second cathode contact at the first end of the substrate and coupled to the second anode contact at the second end of the substrate; a third plurality of solid state light emitting devices (LEDs) on the substrate, wherein the third plurality of LEDs are connected in series to form a third string of LEDs of a second color different from the first color, the third string coupled to the third anode contact at the first end of the substrate and coupled to the third cathode contact at the second end of the substrate; and a fourth plurality of LEDs on the substrate, the fourth plurality of LEDs connected in series to form a fourth string of LEDs of the second color, the fourth string fourth cathode contact at the first end of the substrate and coupled to the fourth anode contact at the second end of the substrate.
