Abstract: The methods and apparatus for lighting systems provide a camera integral to a particular image projection lighting device (IPLD) to capture the projected image from the particular IPLD. The captured image can then be sent over a communication system to the operator for viewing on a visual display device such as a computer monitor on a central controller. Using the captured image of the projected image as viewed upon the display device, the operator may then command using the central controller the focusing, position or other parameters of the projected image upon the stage or projection surface to the desired value. The captured image may also be used, such as by a central control system, to automatically, and without operator intervention, adjust parameters of the IPLD to desired values.

Abstract: A multiparameter light is a type of theater light that includes an arc lamp and a shutter in combination with one or more optical components for creating various lighting effects, suitable electrical and mechanical actuating components, and suitable power supplies. The arc lamp power supply has a variable power output for generating flashes from the arc lamp and for maintaining the arc lamp in an operation condition during dark intervals between the flashes. Flashes may be generated in a series to realize a stroboscopic effect or a lightning effect. The shutter may be used collaboratively with the flashing of the arc lamp to optimize flash characteristics and increase effect options beyond those obtainable from flash or shutter individually. The generation of flashes and operation of the shutter are controlled by a control system in the multiparameter light.

Abstract: A lighting system includes a central controller and multiparameter lights, including IPLDs. A display of the multiparameter lights at the central controller includes the IPLDs and their image parameters, which are used to evoke a display of graphics tools at the central controller for originating images. Images originating at the central controller are transmitted to the IPLDs either by or under control of the central controller. The graphics tools may also be able to manipulate images. The central controller is provided with one or more image editors, which include the graphics tools. The outputs of the image editors, which are referred to as “image banks,” are routed to multiple multiparameter lights (including IPLDs) in accordance with assignments made by the operator of the central controller. The central controller also uses a collage display screen of a collage generator to allow the operator to select an image to collage.

Abstract: A multiparameter light typically includes a lamp and shutter in combination with one or more optical components, various electrical and mechanical components for operating the optical components, suitable electronics for controlling the parameters of the multiparameter light, and suitable power supplies for the lamp, motors, and electronics. Typically, the lamp is enclosed by the lamp housing, which also contains the other optical components and many of the electrical and mechanical components which operate them. As the lamp and the various components within the lamp housing generate a great deal of heat and as components within the multiparameter light can overheat as a result of various orientations and light makeup parameters, the temperature of components within the lamp housing is managed by controlling the amount of power furnished to the lamp or the amount of light transmitted through the shutter in accordance with the orientation of the multiparameter light and/or the light makeup parameter in use.
