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.
Claims83
An image projection lighting device comprising:
- a base housing;
- a yoke;
- a lamp housing;
- the base housing comprising
- a processing system;
- a communications port;
- the lamp housing comprising
- a video projector;
- an antireflective aperture;
- a cooling system;
- and
- a filter.
16 The image projection lighting device of claim 15 wherein
- the signal indicates a filter service alert.
A central controller for a plurality of image projection lighting devices comprising:
- a visual display device;
- and
- an input keypad;
- a first input device for providing commands to be sent from the central controller over a communications system to the plurality of image projection lighting devices for controlling a first separate colored image projected from a first image projection lighting device of the plurality of image projection lighting devices;
- and
- wherein the first input device provides an operator of the central controller with the ability to incrementally fade up the projected first separate colored image to form a projected first separate colored light that is void of an image.
An image projection lighting device comprising:
- a base housing;
- a yoke;
- a lamp housing;
- a processing system;
- and a communications port;
- the lamp housing comprising;
- a projection lamp;
- a light valve;
- and a projection lens;
- wherein service information concerning the image projection lighting device is transmitted by the image projection lighting device from the communications port to a central controller.
An image projection lighting device comprising:
- a base housing;
- a yoke;
- a lamp housing
- a processing system;
- a communications port;
- a multicolor video display device;
- a projection lamp;
- a light valve;
- and a projection lens;
- wherein the projection lamp, light valve and the projection lens are located within the lamp housing;
- and wherein the processing system, the communications port and the multicolor video display device are located within the base housing.
An image projection lighting device comprising:
- a base housing;
- a yoke;
- a projection lamp;
- a light valve;
- a projection lens;
- a processing system;
- and a communications port
- wherein the projection lens projects a first image comprised of first, second, and third separate colored images and the first separate image projected on the projection surface can be faded up to project light that is void of an image on the projection surface by a first command received at the communications port.
An image projection lighting device comprising:
- a base housing;
- a yoke;
- a lamp housing;
- a processing system;
- a communications port;
- a projection lamp;
- a light valve;
- and a projection lens;
- wherein the projection lamp, the light valve, and the projection lens are located within the lamp housing;
- wherein the projection lens projects a colored image on a projection surface comprised of first, second, and third separate colored images and wherein any of the first, second, and third separate colored images projected on the projection surface can be faded up to form projected light that is void of an image on the projection surface by a command received at the communications port.
An image projection lighting device comprising:
- a base housing;
- a yoke;
- a lamp housing;
- a processing system;
- and a communications port;
- a projection lamp;
- a light valve;
- a projection lens;
- and
- wherein the projection lamp, the light valve, and the projection lens are located within the lamp housing;
- wherein the projection lens projects a first separate colored image on a projection surface which is comprised of a plurality of pixels, each of which may be in an inactive, partially active, or a substantially fully active state, wherein at least a first pixel of the plurality of pixels is in a different state from a second pixel of the plurality of pixels;
- and wherein the first separate colored image projected on the projection surface is faded up so that all of the pixels of the plurality of pixels of the first separate color become substantially fully active to project the first separate color on the projection surface void of an image by commands received at the communications port.
An image projection lighting device comprising:
- a base housing;
- a yoke;
- a lamp housing;
- a processing system;
- a communications port;
- and
- an image control for controlling pixel maps;
- a projection lamp;
- a light valve;
- a projection lens;
- wherein the lamp housing comprises a projection lamp, a light valve, and a projection lens;
- wherein the projection lens projects a first pixel map of a first separate color having all pixels inactive and the pixels of the pixel map are controlled by the image control incrementally to form a second pixel map for the first separate color of all pixels substantially fully active projecting the first separate color pixels on the projection surface to project the first separate color as light void of an image by commands received at the communications port.
