Abstract
Abstract A fiber optic light source is disclosed that comprises a three part heat sink structure for absorbing and transmitting heat out of the interior of the light source to thereby reduce the possibility of heat damage. The heat sink structure comprises an internal stationary heat sink in thermal contact with external stationary and movable heat sinks. The movable heat sink acts as a turret which functions to align fiber optic cables with one or more light sources.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
155 words
In a fiber optic light source for illuminating a fiber optic cable, including a cabinet and one or more light sources disposed within said cabinet for providing light, said cabinet being provided with one or more cabinet openings through which said light may pass, the improvement comprising an external heat sink adjoining the outside of said cabinet in the proximity of said openings and comprising a stationary portion and a movable portion rotatably disposed within said stationary portion, said movable portion comprising one or more openings into which said fiber optic cable may be inserted such that rotation of said movable portion will alternately align said fiber optic cable with each of said cabinet openings to thereby provide light to said fiber optic cable, said external heat sink functioning to absorb and conduct heat out of said cabinet to thereby preventing heat damage to either the fiber optic light source or the fiber optic cable.
Claim 2
Dependent Claim
155 words

Claim 3
Dependent Claim
31 words
A fiber optic light source according to claim 1 further comprising an internal heat sink adjoining the inside surface of said cabinet and in thermal contact with said external heat sink.
Claim 4
Dependent Claim
31 words
A fiber optic light source according to claim 2 wherein said internal heat sink comprises one or more openings corresponding to said cabinet openings and through which said light may pass.
Claim 5
Dependent Claim
29 words
A fiber optic light source according to claim 1 wherein said movable portion comprises a plurality of openings of various sizes to accommodate fiber optic cables of various sizes.
Claim 6
Dependent Claim
30 words
A fiber optic light source according to claim 1 wherein said movable portion is substantially cylindrically shaped and rotates within a cylindrical well in the center of said stationary portion.
Claim 7
Dependent Claim
64 words
A fiber optic light source according to claim 1 wherein said movable portion comprises one or more recessed holes containing a spring loaded ball which is in contact with a groove in said stationary portion and which will engage one or more position stops as said movable portion is rotated to thereby accurately align said openings in said movable portion with said cabinet openings.
Claim 8
Dependent Claim
40 words
A fiber optic light source according to claim 2 wherein said internal and external heat sinks are connected by a pin that passes through one of said heat sinks and through said cabinet into the other of said heat sinks.
Claim 9
Dependent Claim
67 words
A fiber optic light source according to claim 1 further comprising an adaptor which fits onto one of said openings in said movable portion and which comprises an opening of a size different than the size of said opening into which said adaptor is inserted, said opening in said adaptor designed to receive a fiber optic such that light may be transmitted to said fiber optic cable.
Claim 10
Dependent Claim
34 words
A fiber optic light source according to claim 1 further comprising an extended portion extending from the surface of said movable portion, said extended portion usable as a handle to move said movable portion.
Claim 11
Dependent Claim
33 words
A fiber optic light source according to claim 9 wherein said extended portion comprises an opening to receive a fiber optic cable such that light may be transmitted to said fiber optic cable.
Claim 12
Dependent Claim
25 words
A fiber optic light source according to claim 9 wherein said extended portion comprises a heat shield on the outer surface of said extended portion.
Claim 13
Dependent Claim
17 words
A fiber optic light source according to claim 11 wherein said heat shield is formed of Delrin.
