ABSTRACT:
The present invention is directed toward a light concentration and collimation device including a tapered body concentrator and a curved, preferably parabolic, reflective collimator combined in a unit such that the apex of the tapered body extends into the reflective collimator through its apex. The concentrator is preferably hollow with a reflective inner surface to funnel light from the base to the apex where an aperture allows the concentrated light to enter the collimator proximate to its focus. The light is then reflected from the inner surface of the collimator to form a beam of collimated light. The concentration and collimation device is particularly useful in visual display apparatus and may be combined with a spectral peak light source and a spectral distributor to produce individual collimated beams of light at specific wavelengths.
