Image projection lighting device

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.

1 . 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 variable 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.    
   
   
       2 . The central controller of  claim 1  wherein 
 the first input device can be controlled by the operator to incrementally fade down the first separate colored image projected from the first image projection lighting device until the first separate colored image is not projected with any substantial light created by the first separate color.    
   
   
       3 . The central controller of  claim 1  further comprising 
 a second input device; and    a third input device.    
   
   
       4 . The central controller as in  claim 3  wherein 
 the first, second, and third input devices are used to control the red, green and blue separate colors, respectively.    
   
   
       5 . The central controller of  claim 3  wherein 
 the first input device is a linear potentiometer    
   
   
       6 . A lighting controller for a plurality of image projection lighting devices comprising: 
 a visual display device;    an input keypad;    a first input device for providing variable commands to be sent from the lighting 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    a second input device for providing variable commands to be sent from the lighting controller over a communications system to the plurality of image projection lighting devices for controlling a second 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 lighting 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.    and wherein the second input device provides an operator of the lighting controller with the ability to incrementally fade up the projected second separate colored image to form a projected first separate colored light that is void of an image.    
   
   
       7 . The lighting controller of  claim 6  wherein 
 the first input device can be controlled by the operator to incrementally fade down the first separate colored image projected from the first image projection lighting device until the first separate colored image is not projected with any substantial light created by the first separate color    and wherein the second input device can be controlled by the operator to incrementally fade down the second separate colored image projected from the first image projection lighting device until the second separate colored image is not projected with any substantial light created by the second separate color.    
   
   
       8 . The lighting controller of  claim 6  wherein 
 the first input device is comprised of a rotary device.    
   
   
       9 . The lighting controller of  claim 6  wherein 
 the first input device is comprised of a linear action device    
   
   
       10 . The lighting controller of  claim 6  wherein 
 the variable commands for controlling the first and second separate colors are compliant with DMX protocol.    
   
   
       11 . The lighting controller of  claim 10  wherein 
 the variable commands for controlling the first separate color are transmitted over a first channel of the DMX protocol and the variable commands for controlling the second separate color are transmitted over a second channel of the DMX protocol.
