Abstract

The present disclosure is directed to illumination techniques that include the use of one or more sets of Light Emitting Diodes or LEDs as light sources in a console/module system. The LED light sources can be utilized to produce a light beams with a specified/combination of intensity and spectrum. Of course, embodiments according to the present disclosure are not limited to one intensity/spectrum but multiple combinations of intensity and spectrum can be implemented. Such systems/methods can be implemented with various optical elements including filter, lenses, mirrors, and/or optical fibers. The system is controlled by voice activation, touch screen, footswitch or wireless communication. The LEDs might also be pulsed as a driving system. The optical fiber cable is tethered to the control.
