Abstract
A system of digitally controlling light output by producing separate control signals for different colors of light. The light is contained in an optical waveguide, either prior to shaping or after shaping. Each of the control signals is coupled to a digitally controlled device which controls the shape of the light output. The digital controlling device can be digital mirror devices, for example.
Claims20
A light controlling computer system, comprising:
- a light controlling computer producing a light beam controlling output, including a first channel for controlling a first aspect of light shaping and a second channel for controlling a second aspect of light shaping, said first aspect relating to a first aspect that controls an outer perimeter of a projected light beam, and said second aspect relating to a second aspect that controls the outer perimeter of the shaped light being, wherein the second aspect is different than the first aspect, and wherein said light beam is shaped based on the collective results of those said first Channel and said second channel, and wherein each of said channels include digital information in a format that control a digitally controllable, pixel level light controlling element.
A method, comprising:
- using a light controlling computer to produce a first Channel which controls a first aspect of light shaping, and to produce a second channel that controls separately a second aspect of light shaping, said first and second aspects collectively control shaping an outer perimeter of a light beam using said first and second channels, and where each of said first and second channels includes digital information in a form that controls a digitally controlled light shaping device that controls shaping of light on a pixel by pixel basis.
A system, comprising:
- a light source, having a power output a more than 100 W;
- an optical waveguide, located in a position which has a first receiving part that receives said light output from said light source and has a second transmitting part that produces an output light based on light received from the first receiving part;
- a pixel level controllable, digitally controllable light controlling element, adjacent said second transmitting part of said optical waveguide, and receiving said output light therefrom;
- and
- a controller, that controls said digital pixel level controllable light, in a way that changes a characteristic of light that is transmitted towards an object of illumination.
