Abstract
Abstract Lighting effects for theaters, advertising, etc., are obtained by a lighting apparatus having at least one coherent light source, preferably a gas laser beam, projecting a beam of light onto and/or through an effect member so that various lighting sensations and/or patterns are simply and easily produced. The lighting effect member may advantageously comprise a translucent disk which is rotated by a motor. The disk may include thermally responsive material, a liquid material, glass configurations, a lacquer layer having a thickness equal to many light-wave lengths etc. One or more light beams may be employed and the effect member may include a plurality of disks arranged one behind the other.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
122 words
A lighting apparatus for producing lighting effects and patterns comprising at least two coherent light sources for providing coherent light beams of different colors, light effect producing means for imparting a change in a coherent light beam projected thereon, and means for directing the coherent light beams onto the light effect producing means, said means for directing including a first mirror for reflecting the coherent light beam from one source into a path directed at the light effect producing means, and a permeable dichroic mirror associated with each of the remaining sources of coherent light, said dichroic mirrors being arranged in said path for reflecting the colored beam of its associated coherent light source into said path while passing the remaining colors.
Claim 2
Dependent Claim
122 words
A lighting apparatus for producing lighting effects and patterns comprising at least two coherent light sources for providing coherent light beams of different colors, light effect producing means for imparting a change in a coherent light beam projected thereon, and means for directing the coherent light beams onto the light effect producing means, said means for directing including a first mirror for reflecting the coherent light beam from one source into a path directed at the light effect producing means, and a permeable dichroic mirror associated with each of the remaining sources of coherent light, said dichroic mirrors being arranged in said path for reflecting the colored beam of its associated coherent light source into said path while passing the remaining colors.
Claim 3
Dependent Claim
90 words
A lighting apparatus for producing lighting effects and patterns comprising at least one coherent light source providing a coherent light beam, light effect producing means for imparting a change in a coherent light beam projected thereon, said lighting effect producing means comprising a translucent carrier member having a lacquer layer disposed thereon, said layer having variations in its thickness to provide a texture surface, and means for directing the coherent light beam onto the light effect producing means so that various light effects and patterns are generated by the apparatus.
Claim 4
Dependent Claim
90 words
A lighting apparatus for producing lighting effects and patterns comprising at least one coherent light source providing a coherent light beam, light effect producing means for imparting a change in a coherent light beam projected thereon, said lighting effect producing means comprising a translucent carrier member having a lacquer layer disposed thereon, said layer having variations in its thickness to provide a texture surface, and means for directing the coherent light beam onto the light effect producing means so that various light effects and patterns are generated by the apparatus.
Claim 5
Dependent Claim
25 words
A lighting apparatus according to claim 2, wherein said lacquer layer has portions of a thickness of many wave lengths of the coherent light beam.
