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.

Claims (33)

1. An apparatus for projecting images upon a stage comprising;

a housing;

a first communications port;

a first system comprised of a first light valve and a lamp, wherein the first system projects red, green, and blue separate images for projecting a first multicolored image upon a stage, and wherein the first system derives the first multicolored image from a first content;

a second system comprised of a multicolor video display device that is a component of the housing wherein the second system displays red, green and blue separate images for displaying a second multicolored image to an operator, wherein the second system derives the second multicolored image from a second content;

and wherein the first content and the second content are received by the first communications port.

2. The apparatus of claim 1 further comprising

a memory; and

wherein the second content is stored in the memory.

3. The apparatus of claim 1 further comprising

a second communications port and the second communication port is compliant with DMX protocol.

4. The apparatus of claim 1 further comprising

a service alert displayed by the second system to the operator.

5. The apparatus of claim 4 wherein

the service alert is a filter service alert.

6. The apparatus of claim 1 wherein

the first content and the second content are the same and the second system displays a preview of the first content to the operator.

7. The apparatus of claim 1 wherein

the image control system is comprised of a computer video card.

8. An apparatus for projecting images upon a stage comprising:

a housing;

a first communications port;

an image control system;

a first system comprised of a first light valve and a lamp which projects red, green and blue separate images for projecting a first multicolored image upon a stage, wherein the first multicolored image is derived from a first content;

a second system comprised of a multicolor video display device that is a component of the housing, wherein the second system displays red, green and blue separate images for displaying a second multicolored image to an operator;

wherein the second multicolored image is derived from a second content;

wherein the image control system alters the first content when a command is received by the first communications port.

9. The apparatus of claim 8 wherein

the image control system alters the first content by rotating the first multicolored image.

10. The apparatus of claim 9 wherein

the image control system alters the first content by keystone correction of the first multicolored image.

11. The apparatus of claim 9 wherein

the image control system alters the first content by altering the image intensity of the first multicolored image.
