Abstract: A lamp unit with a relay lens that allows two different focus points. Two different optical altering elements are hence simultaneously in focus. The elements can be taken in and out of focus to allow different effects.

Abstract: A light pattern generator that can be used to form a gobo for use in a projection optical system. A transparent plate is coated with a stack that is absorptive and reflective. The stack is formed to be ablatable in the form of a pattern. The stack can have multiple different layers with multiple different characteristics, all of which are ablated by the laser.

Abstract: A retrofit kit for an existing lamp uses its lighting and optical structure to retrofit existing lamp and use the existing lens of the lamp. The new lamp also includes electronic controls which enable remotely or manually controlling the lamp, and also enable other functions.

Abstract: A new LED luminare with movable for now lens, and an aspheric lens to collect light from the LED which is optimized for maximizing light output when the Fresnel lens is furthest from the LED source. For now lens can be moved closer and further to vary between floodlight and spotlight.

Abstract: Spot illumination apparatus and methods are described. According to one implementation a spot luminaire includes a light source for emitting a beam of light and a projection lens configured to project the beam of light towards a distant target. A first field stop, through which the beam of light passes, is positioned between the light source and the projection lens. A filter apparatus is positioned proximate the first field stop and is adapted for selectively moving at least one variable density filter across the beam of light. A relay lens group is positioned between the first field stop and the projection lens. The relay lens group is configured to prevent the at least one variable density filter from being imaged by the projection lens. Methods for providing stage lighting are also described.

Abstract: An optical system, light fixture and method are provided that include a light source, a non-circular aperture, a filter apparatus, and a lens. The light source produces a first beam of light, a portion of which is passed by the non-circular aperture. The filter apparatus is positioned proximate to the non-circular aperture and is operable to selectively position a desired portion of a variable density filter in the portion of the first beam of light passed by the non-circular aperture. The lens collects the portion of the first beam of light passed by the non-circular aperture to produce a second beam of light.

Abstract: An optical system, projector and method are provided that include a projection gate between a light source array and a projection lens. The projection lens projects an image of the projection gate. A relay lens group between the light source array and the projection gate prevents the projection lens from projecting an image of the light source array. A lamp housing is provided for use with a projector housing. The lamp housing includes a light source array and a relay lens group located between the light source array and a projection gate in the projector housing. An illumination source for optical fibers is provided that includes a relay lens group between a light source and a coupling in a housing. The relay lens group prevents an image of the light source from being formed at input ends of optical fibers positioned in the coupling.

Abstract: Systems and methods for projecting motion pictures using a light source comprising an electrodeless lamp (12, 54). The electrodeless lamp (12, 54) may be used with a motion picture film projector or a so-called “digital cinema” projector, as well as a projector for projecting still images. The electrodeless lamp (12, 54) may be operated in a pulsed mode, thereby eliminating the need for a shutter in a typical film projector. The light source also may employ a plurality of electrodeless lamps (32, 61, 62, 63, 64, 65, 66, 80). Each lamp may be selected to provide radiation corresponding to a different spectral composition. For example, the lamps may emit red, blue, and green light to illuminate a plurality of “Digital Micromirror Devices” (58) or other digital imaging means.

Abstract: A zoomable light beam spreader comprising first and second multiple-lens arrays includes a plurality of plano-convex lenses in correspondence with a plurality of plano-concave lenses having matched, curved optical surfaces. In a zero-power state, the two multiple-lens arrays are very closely spaced so that the matched convex and concave surfaces effectively cancel each other optically but, as the two arrays are separated coaxially along the axis of a light beam, beam divergence angle increases as a function of the distance of separation. A large amount of beam divergence is obtained when the curved surfaces of the plano-concave lenses of the second array are positioned beyond the focus points of the plano-convex lenses of the first array.
