摘要： A theatrical follow spot utilizes elliptic reflective optics to achieve compact size and non-astigmatic projection. A source lamp is situated in front of the mirror, sufficiently offset to one side thereof so as to be out of the path of reflected light. The mirror has the shape of an ellipsoid of revolution, the mirror section being entirely on one side of a meridian plane of the ellipsoid. The axis of light from the source lamp is coincident with a line through the near focus of the ellipsoid and the center of the mirror. This insures that an image in the near focal plane, such as the circular opening of an iris, will be projected at the distant focal plane of the ellipsoid, without distortion of shape.

摘要： In a dimmer circuit a summing amplifier combines a light intensity control voltage with a feedback voltage derived from the thyristor controlled ac power supplied to the lamp load. The summing amplifier output establishes the steepness of a ramp signal produced each ac half cycle by a ramp generator. A trigger circuit fires the thyristor device when the ramp signal reaches a certain level. In the feedback circuit a signal transformer coupled from the load is rectified, shaped by filter networks at the rectifier input and output, and used to charge a capacitor via an isolation amplifier. This capacitor provides a feedback voltage which, when summed with the control voltage, achieves a desired functional relationship between control voltage and light intensity, with compensation for load variation. A gapped core inductor is series connected with the ac supply to minimize certain adverse effects associated with turn-on of the thyristor device. Thus, use of the inductor reduces lamp filament vibration and minimizes inductive coupling to adjacent audio and other low level circuits. The inductor core includes both small and large air gaps to provide maximum inductance over a wide range of load current.

摘要： A lamp rotation socket useful in a luminaire comprising an array of standard sealed beam lamps, each of which has a filament orientation and reflector configuration that produces a generally oval field of illumination. A plurality of elongate housings are provided, each housing mounting a set or line of lamps. The housings are mounted in side-by-side relationship and are each individually angularly movable about their longitudinal axes to achieve a desired overlap or separation of illumination fields. By rotating the lamps in their individual sockets, different illumination effects can be achieved. The improvement resides in a vastly simplified socket and lamp mounting in which the socket, fixed to the housing, receives the lamp posts in both of the two alternate 90* lamp positions.

摘要： A dimmer circuit for controlling the light intensity from a lamp by adjusting the firing angle of a silicon controlled rectifier (SCR) or like control element supplying ac power to the lamp. The circuit comprises a firing angle function generator which produces, in sync with each ac half cycle, a signal f( Alpha ) monotonically related in amplitude to SCR firing angle. Comparator circuitry triggers the SCR''s when the signal f( Alpha ) crosses the level of a light intensity control signal linearly related e.g., to dimmer control handle position. In one embodiment, the function generator includes a capacitor charged at preselected rates during portions of each ac half cycle. The firing angle function thereby synthesized is programmable to implement any desired dimmer response.

摘要： A luminaire mounts an array of standard sealed beam lamps each of which has a filament orientation and reflector configuration that produces a generally oval field of illumination. A plurality of elongate housings are provided, each housing mounting a set of lamps. The housings are mounted in side-by-side relationship and so that the housings can be rotated to achieve a desired degree of overlap or a desired degree of spacial relationship of the illumination fields produced by the sets of lamps. The luminaire can be turned 90* so that the spreading or overlap can take place either in a horizontal direction or a vertical direction as desired. Filament orientation can be determined independently.

The mechanism comprises a movable clamping plate connected to one of the clamp members by coiled compression springs and a cam for moving the clamping plate against the action of the compression springs.

摘要： Each leg of the tripod carries a leg extension by the aid of a simple pin and slot connection. In the retracted position the leg extension allows the main leg to contact the floor. The leg extension is moved to operative projected position by a combination of simple angular and sliding movements. The leg extension can be, and normally is, locked against angular movement in both retracted and projected positions.

摘要： The reflector part of the luminaire is made in sections hinged to the main housing. Each section is foldable from a first extended operative position in which the sections project rearwardly away from the reflector opening to a second position in which all of the sections are located close to the plane of the opening of the reflector.
