Patent ID: 6857772

Claim:
A surgical light head device comprising: a light source which provides optical energy; an integrating cavity positioned to receive said optical energy, wherein said integrating cavity outputs spatially uniform optic energy: a concentrator positioned to receive optic energy from said integrating cavity, wherein said concentrator includes an entrance aperture positioned toward said integrating cavity and an exit aperture positioned away from said integrating cavity, wherein said entrance aperture is smaller than said exit aperture, wherein said concentrator angularly aligns optical energy received from said integrating cavity creating aligned optical energy, and wherein said concentrator outputs aligned optical energy through said exit aperture; an optic filter positioned to receive optical energy from said concentrator, wherein said optical fiber reflects optical energy creating reflected optical energy, wherein said optical filter transmits optical energy creating transmitted optical energy; a reflector positioned to receive said transmitted optical energy, wherein said reflector reflects said transmitted optical energy to an illumination region, wherein said illumination region includes an illumination pattern; an intensity controller positioned between said reflector and said optical filter, wherein said intensity controller controls the amount of optical energy received by said reflector; an illumination pattern controller positioned to control a of said illumination pattern; and a heat dissipater positioned to dissipate heat generated from said light source.
