Claim 6

The light projector of claim 1 wherein said wand includes a fiber optic cable extending between one end of said rod and the other end thereof for transmitting a portion of said light stream to said other end of said rod.

Claim 7

The light projector of claim 1 wherein said wand includes an opaque sheath surrounding said rod over a majority of said rod's periphery, said sheath having an opening along a side thereof extending along the length of said rod.

Claim 8

The light projector of claim 6 wherein said sheath has a non-reflective outer surface, a curved surface located about the periphery of said rod, and sides which extend from said curved surface to said opening.

Claim 9

The light projector of claim 7 wherein the interior surfaces of said sides of said sheath include a non-reflective surface.

Claim 10

The light projector of claim 6 wherein said sheath includes a mating connector for attachment to said optical connection at one end thereof and an opaque end cap at the other end thereof.

Claim 11

The light projector of claim 1 wherein said optical connector includes a fiber optic cable having mating connectors on each end thereof for attachment to mating connectors on said light source and on said wand.

Claim 12

The light projector of claim 1 wherein said elongate beam is relatively narrow compared to its length.

Claim 13

A movable light projector in combination with a light-tight enclosure having a light source, for providing a light stream, therein, an elongate, light transmitting cable extending from the light source and terminating in a connector, and an auxiliary shutter, the movable light projector comprising: an elongate light wand for converting the light stream into an elongate light beam, said wand including a mating connector for attaching said wand to said connector on the light transmitting cable.

Claim 14

A movable light projector in combination with a light-tight enclosure having a light source, for providing a light stream, therein, an elongate, light transmitting cable extending from the light source and terminating in a connector, and an auxiliary shutter, the movable light projector comprising: an elongate light wand for converting the light stream into an elongate light beam, said wand including a mating connector for attaching said wand to said connector on the light transmitting cable.

Claim 15

The combination of claim 12 wherein said wand includes an elongate rod, having a round cross-section, formed of transparent material, wherein said light beam is emitted along the side of said rod.

Claim 16

The combination of claim 13 wherein said rod includes a light refracting surface thereon.

Claim 17

The light projector of claim 13 wherein said rod has a flat surface formed thereon, wherein grooves are formed on said flat surface, and wherein said flat surface forms a tapered portion of said rod, said tapered portion beginning adjacent one end of said rod and extending towards said other end of said rod, said grooves extending normal to the major axis of said rod, which includes a refractive surface fixed along said tapered portion, wherein the light stream is refracted by said grooves in the interior of said rod and is emitted as a light beam from a smooth side of said rod, which is located opposite said flat surface.

Claim 18

The combination of claim 13 wherein said wand includes a fiber optic cable extending between one end of said rod and the other end thereof for transmitting a portion of said light stream to said other end of said rod.

Claim 19

The combination of claim 13 wherein said wand includes an opaque sheath surrounding said rod over a majority of said rod's circumference, said sheath having an opening along a side thereof extending along the length of said rod, wherein said sheath has a non-reflective outer surface, a curved surface located about the periphery of said rod, and sides which extend from said curved surface to said opening, including a non-reflective surface on the interior thereof.

Claim 20

The combination of claim 12 which further includes controls for the auxiliary shutter on the connector.

Claim 21

A light projector for emitting a light beam wherein the emitted light beam has substantially even intensity of light along the length of the projector, wherein a light source coupled to the projector provides a light stream thereto, comprising: an elongate rod, formed of transparent material, for transmitting a light beam along one, smooth surfaced side thereof, and including a light refractive, grooved, flat surface located thereon, wherein said flat surface forms a tapered portion of said rod, said tapered portion beginning adjacent one end of said rod and extending towards another end of said rod.

Claim 22

A light projector for emitting a light beam wherein the emitted light beam has substantially even intensity of light along the length of the projector, wherein a light source coupled to the projector provides a light stream thereto, comprising: an elongate rod, formed of transparent material, for transmitting a light beam along one, smooth surfaced side thereof, and including a light refractive, grooved, flat surface located thereon, wherein said flat surface forms a tapered portion of said rod, said tapered portion beginning adjacent one end of said rod and extending towards another end of said rod.

Claim 23

The light projector of claim 19 which further includes a reflective surface fixed along said tapered portion to direct the light stream through said smooth side.

Claim 24

The light projector of claim 19 wherein said rod has a round cross section.

Claim 25

The light projector of claim 19 which includes a connector and wherein the light source is coupled to said rod through said connector at said one end of said rod.

Claim 26

The light projector of claim 22 which includes a fiber optic cable extending between one end of said rod and said other end thereof for transmitting a portion of the light stream to said other end of said rod.
