Patent ID: 8766885

Claim:
A light module, comprising: a printed circuit board; a matrix of substantially flat full color pixels mounted on a first surface of the printed circuit board, each of the pixels comprising a red light emitting diode that emits in the red portion of the visible spectrum, a green light emitting diode that emits in the green portion of the visible spectrum, and a blue light emitting diode that emits in the blue portion of the visible spectrum, wherein the pixels are arranged in a plurality of rows and columns; and a driving circuit configured to selectively activate the light emitting diodes, wherein the driving circuit comprises red, green and blue column drivers configured to selectively activate columns of red, green and blue light emitting diodes; first, second and third individually adjustable current limiting devices coupled to respective ones of the red, green and blue column drivers; and at least one resistor in series between the driving circuit and the red light emitting diodes, wherein the driving circuit is mounted on the printed circuit board.
