Lighting Devices with Automatic Lighting Adjustment

Abstract

Lighting systems and associated controls that can provide active control of lighting device settings, such as on/off, color, intensity, focal length, beam location, beam size and beam shape. In some examples, lighting systems may include eye tracking technology and sensor feedback for one or more lighting device settings and may be configured with depth perception and cavity or incision recognition capability through image or video processing.

What is claimed is: 
     
         1 . A method of controlling a surgical lighting device, comprising:
 capturing, by an image capture device, an image of a surgery field;   detecting, with a processor, an incision in the image;   determining, with the processor, at least one property of the incision; and   adjusting, by the processor, at least one setting of the surgical lighting device to illuminate the incision based on the at least one property of the incision.   
     
     
         2 . The method of  claim 1 , wherein the at least one property of the incision comprises at least one of a size, shape, and depth of the incision. 
     
     
         3 . The method of  claim 1 , wherein:
 determining at least one property of the incision comprises determining a size of the incision; and   adjusting at least one setting of the surgical lighting device comprises adjusting a beam size according to the determined size of the incision.   
     
     
         4 . The method of  claim 1 , wherein:
 determining at least one property of the incision comprises determining a shape of the incision; and   adjusting at least one setting of the surgical lighting device comprises adjusting a beam shape according to the determined shape of the incision.   
     
     
         5 . The method of  claim 1 , wherein:
 determining at least one property of the incision comprises determining a depth of the incision; and   adjusting at least one setting of the surgical lighting device comprises adjusting a beam focal length or intensity according to the determined depth of the incision.   
     
     
         6 . The method of  claim 1 , further comprising:
 matching, by the processor, the detected incision with a first incision in a plurality of incisions stored in an incision database, the incision database associating each of the plurality of incisions with a predefined surgical lighting device setting;   wherein adjusting at least one setting of the surgical lighting device comprises adjusting the at least one setting to correspond to the predefined surgical lighting device setting associated with the first incision.   
     
     
         7 . A lighting system, comprising:
 an image capture device configured to capture an image of a surgery field;   a surgical lighting device; and   a processor coupled to the image capture device and the surgical lighting device configured to:
 detect an incision in the image; 
 determine at least one property of the incision; and 
 adjust at least one setting of the surgical lighting device to illuminate the incision based on the at least one property of the incision. 
   
     
     
         8 . The system of  claim 7 , wherein the at least one property of the incision comprises at least one of a size, shape, and depth of the incision. 
     
     
         9 . The system of  claim 7 , wherein the at least one property of the incisions comprises a size of the incision and the processor is further configured to:
 adjust a beam size of a light beam emitted by the surgical lighting device according to the determined size of the incision.   
     
     
         10 . The system of  claim 7 , wherein the at least one property of the incisions comprises a shape of the incision and the processor is further configured to:
 adjust a beam shape of a light beam emitted by the surgical lighting device according to the determined shape of the incision.   
     
     
         11 . The system of  claim 7 , wherein the at least one property of the incisions comprises a depth of the incision and the processor is further configured to:
 adjust a beam focal length or intensity of a light beam emitted by the surgical lighting device according to the determined depth of the incision.   
     
     
         12 . The system of  claim 7 , wherein the processor is further configured to:
 match the detected incision with a first incision in a plurality of incisions stored in an incision database, the incision database associating each of the plurality of incisions with a predefined surgical lighting device setting;   wherein the processor is configured to adjust at least one setting of the surgical lighting device by adjusting the at least one setting to correspond to the predefined surgical lighting device setting associated with the first incision.
