Light control systems and methods

Abstract

Provided is a light-emitting device control system, comprising a beam steering mechanism that directs a beam of light at a first surface location, wherein an illumination region is formed at the first surface location in response to the directed beam of light, a sensor that recognizes a hand gesture at the illumination region; a processor that converts data related to the hand gesture into a command signal, and a controller that instructs the beam steering mechanism to move the illumination region to a second surface location in response to the command signal corresponding to the hand gesture.

What is claimed is: 
     
         1 . A light-emitting device control system, comprising:
 a beam steering mechanism that directs a beam of light at a surface location, wherein an illumination region is formed at the surface location in response to the directed beam of light;   a sensor that recognizes a hand gesture at the illumination region;   a processor that converts data related to the hand gesture into a command signal;   a controller that instructs the beam steering mechanism to move the illumination region to a second surface location in response to the command signal corresponding to the hand gesture; and   a light source module that outputs the beam of light to the beam steering mechanism for directing the beam of light to the surface location.   
     
     
         2 . The light-emitting device control system of  claim 1 , wherein the beam steering mechanism includes a mechanical device having an axis on which is mounted the light source module. 
     
     
         3 . The light-emitting device control system of  claim 1 , wherein the light source module comprises a lens, and the beam of light is output through the lens. 
     
     
         4 . The light-emitting device control system of  claim 1 , further comprising an optical element on two motorized axes, the optical element directing the beam of light from the light source module at a surface location, wherein the illumination region is formed at the surface location in response to the directed beam of light. 
     
     
         5 . A light-emitting device control system, comprising:
 a beam steering mechanism that directs a beam of light at a surface location, wherein an illumination region is formed at the surface location in response to the directed beam of light;   a sensor that recognizes a hand gesture at the illumination region;   a processor that converts data related to the hand gesture into a command signal;   a light source module that outputs the beam of light to the beam steering mechanism for directing the beam of light to the surface location; and   an optical element that directs the beam of light from the light source module at a surface location, wherein the illumination region is formed at the surface location in response to the directed beam of light.   
     
     
         6 . The light-emitting device control system of  claim 5 , further comprising a controller that instructs the beam steering mechanism to move the illumination region to a second surface location in response to the command signal corresponding to the hand gesture. 
     
     
         7 . The light-emitting device control system of  claim 5 , wherein the optical element is on two motorized axes of the beam steering mechanism. 
     
     
         8 . The light-emitting device control system of  claim 5 , wherein the light source module is positioned on at least one of the two motorized axes. 
     
     
         9 . The light-emitting device control system of  claim 5 , wherein the light source module comprises a lens, and the beam of light is output through the lens.
