Abstract: A lighting system is disclosed comprised of a plurality of image projection lighting devices including a first image projection lighting device. The first image projection lighting device is typically comprised of a microprocessor and a camera. The microprocessor and/or a command from a central controller can cause the camera to capture a first image of the projection surface and can cause the first image projection lighting device to produce a projected light which substantially reduces the nonuniformity of light intensity on the projection surface from the plurality of image projection lighting devices.

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.

A video projector may project a first image comprised of first, second, and third separate images and the first separate image can be faded up to project light that is void of an image by a first command received at the communications port.

Abstract: An image projection lighting device is disclosed having a processor and communications port. The communications port may receive a contrast command.

The lamp housing may be comprised of a lamp and a first light valve. The image projection lighting device may be further comprised of a communications port, a processing system, and a memory. A cutoff value representing an amount of accumulated operating time at which the lamp may begin to operate improperly may be stored in the memory. An accumulated value representing an actual accumulated amount of operating time of the lamp may also be stored in the memory. The processing system may prevent the lamp from operating when the accumulated value is within a limit of the cutoff value, unless the processing system grants a request for a variance.

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.
