Abstract
A high-density LED array (10) capable of presenting a density of X LEDs/unit area has a first printed circuit board (12) having X/2 LEDs/area and X/2 apertures arrayed therewith. A second printed circuit board (22) is spaced from the first printed circuit board (12) and has X/2 LEDs 28/unit area. The LEDs (28) on the second printed circuit board are aligned with the apertures (20) in the first printed circuit board. Each of the LEDs (28) on the second printed circuit board (22) has an optical fiber (30) associated therewith and each of the light guides (30) extends through one of the apterures (20). Each of the mounted LEDs on the first printed circuit board can have an optical fiber associated therewith and the light guides can be bundled to direct light to a remote source.
