Combination light concentrating and collimating device and light fixture and display screen employing the same

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