Abstract
Abstract An improved light console for fiber-optic light cables which carry devices, such as surgical devices to be illuminated by the light source. The improved light source includes a dual illumination system which permits simultaneous use of two cables with the same console, or switching from one cable to another in the event of failure of one light source during surgical operation. In addition, the improved light console employs light and heat shielding means surrounding each of the light sources. The shielding means functions as a heat sink which may be aircooled to protect the front portion of the console thereby preventing it from becoming too hot to touch, a serious defect in prior art consoles. The console also includes means for controlling the light intensity for each of the light sources independent of separate color temperature controls. One embodiment of the light intensity means includes self-indexed, diaphragm or stop-type assembly which can vary the light intensity from 0 - 100 percent of output in any preselected number of discreet stages, typically 0, 25, 50 and 100 percent of maximum. Each light is separately switched independently of the power. The light console is air-cooled by a fan-type motor, and contains standard circuitry and fusing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
169 words
An improved fiber-optic light console comprising in operative combination: a. a housing, having a control panel portion, b. means for mounting one end of a fiber-optic light cable in said control panel portion, c. a high intensity light source having a reflector assembly disposed within said housing so that light from said light source impinges on said eNd of said fiber-optic light cable, d. means for shielding said control panel portion from direct impingement thereon of light from said high intensity light source, e. said shielding means being adapted to pass light therethrough to impinge on said fiber-optic light cable end, and having a shroud disposed between said reflector assembly and the end of said fiber-optic light cable and extending axially rearwardly of said reflector assembly, and f. means for directing ambient air from the exterior of said housing into heat exchange association with said shielding means, whereby said shielding means absorbs radiant heat from said light source and said console has improved operational life, safety and lower temperature.
Claim 2
Dependent Claim
169 words
An improved fiber-optic light console comprising in operative combination: a. a housing, having a control panel portion, b. means for mounting one end of a fiber-optic light cable in said control panel portion, c. a high intensity light source having a reflector assembly disposed within said housing so that light from said light source impinges on said eNd of said fiber-optic light cable, d. means for shielding said control panel portion from direct impingement thereon of light from said high intensity light source, e. said shielding means being adapted to pass light therethrough to impinge on said fiber-optic light cable end, and having a shroud disposed between said reflector assembly and the end of said fiber-optic light cable and extending axially rearwardly of said reflector assembly, and f. means for directing ambient air from the exterior of said housing into heat exchange association with said shielding means, whereby said shielding means absorbs radiant heat from said light source and said console has improved operational life, safety and lower temperature.
Claim 3
Dependent Claim
37 words
A console as in claim 1 which includes: g. means disposed in said housing for controlling the amount of light impinging on the end of said fiber-optic light cable without affecting the color temperature of said light.
Claim 4
Dependent Claim
13 words
A console as in claim 1 which includes a plurality of light sources.
Claim 5
Dependent Claim
48 words
A console as in claim 2 wherein said light amount control means includes a plate having an aperture therein, said plate is spaced rearwardly from the end of said end of said fiber-optic light cable, and means for positioning said aperture in axial alignment with said cable end.
Claim 6
Dependent Claim
36 words
A console as in claim 4 wherein said positioning means includes means for indexing said aperture in a predetermined position, and spring-biased fingers cooperating with said indexing means to provide for positive positioning of said apertures.
Claim 7
Dependent Claim
36 words
A console as in claim 5 wherein said plate includes means for maintaining a portion of said plate in the path of said light impinging on said cable end, thereby to prevent override of said plate.
Claim 8
Dependent Claim
28 words
A console as in claim 6 wherein said maintaining means includes a portion of said plate adapted to engage a portion of said fiber-optic light cable mounting means.
Claim 9
Dependent Claim
183 words
An improved fiber-optic light console comprising in operative combination: a. a housing, having a control panel portion, b. means for mounting one end of a fiber-optic light cable in said control panel portion, c. a high intensity light source disposed within said housing so that light from said light source impinges on said end of said fiber-optic light cable, d. means disposed in said housing for controlling the amount of light impinging on the end of said fiber-optic light cable without affecting the color temperature of said light, said light amount control means includes a plate having an aperture therein, said plate is spaced rearwardly from the end of said fiber-optic light cable, and means for positioning said aperture in axial alignment with said cable end, said positioning means includes means for indexing said aperture in a predetermined position, and spring-biased fingers cooperating with said indexing means to provide for positive positioning of said apertures, and e. means for directing ambient exterior air into association with the interior surfaces of said housing and said light amount control means thereby to cool said console.
Claim 10
Dependent Claim
