Color Tunable Medical Headlamp Bezel

Abstract

A color-adjustable medical headlamp assembly, including a headband assembly and a bezel, which can be worn around a user's head. The bezel contains a light source assembly that is capable of generating light with different colors and intensities, and an optical train that focuses the light generated by the light source assembly. A user input assembly is included to allow for the selection and adjustment of both the color and brightness of the light from the bezel. Also, the rear surface of the bezel has a higher coefficient of thermal conductance compared to the movable portion of the bezel and is an avenue for heat dissipation. Finally, a heat shield is attached to the bezel to cover its rear surface, which can pose a burn hazard after prolonged usage.

1 . A medical headlamp assembly, comprising:
 (a) a headband assembly;   (b) a bezel connected to and supported by a linkage to said headband assembly, including:
 (i) a light source assembly capable of producing light of differing colors and differing intensities; 
 (ii) an optical train for focusing said light from said light source assembly; 
   (c) a user input assembly, permitting a user to adjust the color and intensity of light from said bezel.   
     
     
         2 . The medical headlamp assembly of  claim 1 , wherein said light source assembly is an LED assembly. 
     
     
         3 . The medical headlamp assembly of  claim 1 , wherein said light source assembly is an LED assembly that includes at least three LEDs, each of a different color. 
     
     
         4 . The medical headlamp assembly of  claim 1 , wherein said light source assembly is an LED assembly that includes a red LED, a green LED, and a blue LED. 
     
     
         5 . The medical headlamp assembly of  claim 1 , wherein said user input assembly permits the choice of preset color spectra, adapted for specific tasks. 
     
     
         6 . The medical headlamp assembly of  claim 5 , wherein one preset color spectrum emits less light between 500 nm to 550 nm, in comparison with light between 420 nm and 470 nm. 
     
     
         7 . The medical headlamp assembly of  claim 5 , wherein at least one preset color spectrum causes a first tissue type to contrast with a second tissue type. 
     
     
         8 . The medical headlamp assembly of  claim 1 , including an ultraviolet LED. 
     
     
         9 . The medical headlamp assembly of  claim 1 , including an infrared LED.
