A cyclorama includes a generally enclosed housing having a normally horizontal housing axis and an open front. A reflector proximate the open front has an operative portion that has a substantially uniform cross-section along the housing axis. The reflector has a surface configuration and an LED array is arranged in relation to the reflector surface to provide a higher flux density directed toward a far end of a wall or surface to be illuminated and provide a lower flux density directed toward a direction of the near end of the surface to be illuminated, generating a transition flux density between the far and near ends of the surface to be illuminated. The LED array and/or the reflector have optical features for eliminating shadows in the projected light over the entire illuminated surface.

A combined power and data track lighting system includes an elongated track, having a number of longitudinal guide ways for carrying electrically isolated power and data conductors arranged within at least some or the guide ways. An adapter applies power to the power conductors, and another adapter applies control data to the data conductors. An LED luminaire contains LEDs, each of which can generate a discrete color. A data converter converts data on the data lines to control the currents in the individual LEDs to create a desired composite color. Quartz luminaire, Metal-Halide luminaire, Digital Light Processor (DLP) automated computer luminaire, and DMX controlled devices can be supported and controlled through the track, that can be supported on trusses. The main control data is Remote Device Management (RDM) supplied applied to the data conductors.

A cyclorama light includes a generally enclosed housing forming an interior compartment having a normally horizontal housing axis and an open front defining a window generally arranged within a plane parallel to said axis. A reflector substantially covers the window and has an operative portion that has a substantially uniform cross-section along the housing axis. An LED light emitter array extends along a line substantially parallel to the housing axis, the reflector having a surface configuration and the LED array being arranged in relation to the reflector surface to provide a higher flux density directed toward a far end of a wall or surface to be illuminated and provide a lower flux density directed toward a direction of the near end of the surface to be illuminated, generating a transition flux density between the far and near ends of the surface to be illuminated. The LED array and/or the reflector have optical features for eliminating shadows in the projected light over the entire illuminated surface.

A high-powered lighting assembly includes an easily sealed continuous thermal barrier and a solid-state actively controlled closed-loop refrigeration system to maximize operational efficiencies and increase unit life. The thermal barrier prevents thermal back-flow from a heat sink plate or a housing to a lighting array while insulating a control module and a thermal sensor with improved sealing geometry. The refrigeration system is optimally positioned to controllably pump heat from the lighting array to the heat sink plate.

Peltier-cooled LED lighting assembly

A cyclorama light includes a housing having generally opaque rear, bottom and side walls and an open front wall defining a window that extends from a region proximate to the upper end of the rear wall and a region proximate to the front end of the bottom wall and generally extending between the side walls. The housing defines a housing axis generally parallel to the rear and bottom walls and normal to the side walls. An elongate reflector essentially extends between the side walls and is mounted for rotary movements about the housing axis. An elongate lamp having a lamp axis is mounted on the reflector to maintain the lamp axis substantially coextensively with the housing axis, the reflector being configured to direct light generated by the elongate lamp with a predetermined intensity distribution through the window formed in the open front wall in a direction which is a function of the rotational position of the reflector about the housing axis. A filter is provided for covering the window with a color filter material, as well as an adjustment means for selectively adjusting the rotational position of the reflector about the housing axis. The direction of projection of the light emitted from the housing can thus be modified substantially independently of the specific orientation of the housing.

Cyclorama light

Light assembly for providing a focused image of varying color hue and saturation intensity which includes means for providing a point light source, a filter set in which the filters are complementary colors, and a light mixing channel to pass additively mixed light rays to an objective lens system which produces the focused image.

Color mixing lighting assembly

An apparatus is set forth to spread a pistol stock or grip relative to the associated framework of the pistol to permit ease of removal of the associated stock from the pistol framework. The tool includes an elongate rod, including a handle member transversely and integrally mounted to an upper end of the rod, with a head member mounted at a lowermost end of the rod. The head member includes an elongate rectangular cross-sectional member, including arcuate corners spaced from and parallel to the axis of the head longitudinally aligned with the rod. The kit includes a series of further head members selectively mounted to the rod, wherein the head members include a tapered wedge-shaped member including planar sides and arcuate tapering corners, as well as a further wedge-shaped member defined by an elliptical cross-sectional configuration. The tool further includes at least one sleeve member slidably mounted on the head member to provide various cross-sectional configurations for insertion within magazine wells of pistols of various dimensions. The sleeve is formed of a rigid cellular or polymeric material, as are the head and further head members utilized in the kit assemblage.
