Abstract: An improved image projection lighting device is disclosed. Commands received by a communications port of the base housing may be acted upon to change zoom and focus values of a zoom and focus lens. A cooling system may be provided which compares an input air temperature of the image projection lighting device to an exiting air temperature to determine if a filter needs service. 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: 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: An image projection lighting device is provided which includes a variable homogenizing system. The variable homogenizing system may homogenize light projected by a lamp across a light valve. The variable homogenizing system may vary the light across the light valve from an existing state to a first state or from an existing state to a second state. The variable homogenizing system may be comprised of one or more lens arrays, which may be comprised of cylindrical or spherical lenses.

Abstract: An image projection lighting device is disclosed having a processor and communications port. The communications port may receive a contrast command. The processor may modify contrast of image data in response to the contrast command to form contrast modified image data. The communications port may receive a black level command. The processor may modify image data in response to the black level command to form modified image data having a modified black level. Modified black level image data may be created by adding or subtracting an offset to the image data.

Abstract: An image projection lighting device is disclosed comprising a base housing, a yoke, and a lamp housing. The base housing may include or have located therein, a processing system and a communications port. The lamp housing may include or have located therein, a video projector, an antireflective aperture, a cooling system, and an air filter system. The image projection lighting device may further include a multicolor video display device, which may display a signal indicating a service alert, such as a filter service alert. Service information, concerning the image projection lighting device, may be transmitted by the image projection lighting device from the communications port to a central controller.

Abstract: A stage lighting apparatus is disclosed comprised of a lamp housing. The lamp housing is comprised of a lamp and a first light valve. The stage lighting apparatus is also comprised of a first set of first image data. The first set of first image data is comprised of a first set of first separate color data for operation of a first separate colored image and a second set of second separate color data for operation of a second separate colored image. A swap function is applied to the first set of first image data to allow operation of the second separate colored image as determined by the first separate color data.

Abstract: A lighting system comprised of a central controller, a digital communications path, and a plurality of image projection lighting devices (IPLDs) is provided. The IPLDs contain cameras that can capture both visible light and infrared light. Address signals sent from the central controller first address a particular IPLD and then command signals sent from the central controller control an infrared blocking filter to be positioned in and out of a camera optical path of the particular addressed IPLD.

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.
