Title: |
Optical System for Theatrical and Stage Lighting |
Abstract: |
Various optical system embodiments produce a narrow beam of focused or
unfocused light using a compound parabolic concentrator, lens system, and
high flux density solid-state light source. Various system embodiments
include a solid state light source configured to emit light, and a
compound parabolic concentrator having a smaller opening and a larger
opening opposite the smaller opening, wherein the light source and the
concentrator are operationally positioned with respect to each other for
light from the light source to enter the smaller opening of the
concentrator and exit the larger opening of the concentrator as a
narrower beam of light. Some embodiments include an imaging stage
operationally positioned with respect to the concentrator to receive the
narrower beam of light at an image plane and relay an image plane to a
far field target.
