Dental or surgical operating light

Claim 2

An improved lighting device which comprises a single light source having a filament for providing illumination when energized, reflector means having a reflective surface with an interior and exterior side, said reflector means extending above, below and partially around said light source, a converging lens integral with said reflective surface for gathering and focusing beyond said exterior side of said reflective surface, a portion of the illumination provided by said filament, and an optic bundle having a first end and a second end, said first end being disposed as to receive the light gathered by said converging lens, said second end being displaceable to an area remote to said light source whereby light may be transmitted from said first end to said remote area via said optic bundle.

Claim 3

The lighting device of claim 1 wherein shield means are disposed forwardly of said light source in covering relation to said filament.

Claim 4

The device of claim 2 wherein the side of said shield means closest to said filament is a reflective surface of such configuration so as to reflect a portion of the light impinging thereupon back to said converging lens.

Claim 5

The device of claim 3 wherein the reflective surface of said shield is so shaped as to also reflect light back to the reflective surface of said reflector.

Claim 6

The device of claim 4 further characterized in that the said reflector is vertically oriented and is in the shape of a portion of an elliptic paraboloid having a vertical height greater than the horizontal width and presents a concave surface to said filament.

Claim 7

An improved dental light for illuminating the oral cavity of a patient to facilitate dental and surgical procedures, which light comprises in combination, a light source having a horizontally oriented filament for providing illumination when energized, a vertically oriented reflector means disposed behind said light source and extending vertically above and below said light source, said horizontally oriented filament extending transversely with respect to said vertically oriented reflector means, shield means disposed forwardly of said light source in covering relation to said horizontally oriented filAment, a converging lens disposed within said reflector means at a point behind said light source, said lens receiving and focusing a portion of the illumination provided by said filament, an optic bundle having a first end and a second end, said first end being disposed so as to receive the light focused by said converging lens, said second end being displaceable to an area remote to said light source whereby light may be transmitted from said first end to said remote area via said optic bundle.

Claim 8

An improved dental light for illuminating the oral cavity of a patient to facilitate dental and surgical procedures, which light comprises in combination, a light source having a horizontally oriented filament for providing illumination when energized, a vertically oriented reflector means disposed behind said light source and extending vertically above and below said light source, said horizontally oriented filament extending transversely with respect to said vertically oriented reflector means, shield means disposed forwardly of said light source in covering relation to said horizontally oriented filAment, a converging lens disposed within said reflector means at a point behind said light source, said lens receiving and focusing a portion of the illumination provided by said filament, an optic bundle having a first end and a second end, said first end being disposed so as to receive the light focused by said converging lens, said second end being displaceable to an area remote to said light source whereby light may be transmitted from said first end to said remote area via said optic bundle.

Claim 9

The dental light of claim 6 further characterized in that the side of said shield means closest to said filament is a reflective surface of such configuration so as to reflect a portion of light impinging thereupon back to said converging lens and another portion of light back to said reflector means and wherein a right-angle prism is positioned behind said reflector means, said right-angle prism receiving illumination from said converging lens and thereafter transmitting said illumination to the first end of said optic bundle.
