Abstract
Abstract A photographic light source has a boxlike frame with sockets for mounting and electrically connecting, for continuous operation, fluorescent white light tubes of conventional type distributed about the inner sides of the frame and extending longitudinally of them. Reflectors with light diffusing reflecting surfaces are mounted to extend between the sockets and about light tubes mounted therein, the reflectors having a position in which most of the light from the tubes is directed and reflected into the frame and mainly toward one face of it. The mixture of direct and reflected light reflected by a subject within the frame, or outside that face of it, toward a camera directed into the opposite face of the frame, provides effective lighting for color or black and white pictures, with the predominant green of directly reflected light from such tubes desirably suppressed. Adapters are provided for using the frame for slide viewing and photographing.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
194 words
A photographic light source comprising: a boxlike frame; sockets for mounting and electrically connecting for continuous operation a plurality of fluorescent white light tubes distributed about the inner sides of said frame and extending longitudinally of said sides; and reflectors with light diffusing reflecting surfaces mounted to extend between said sockets and about light tubes mounted therein and having a position relative to said tubes at which most of the light from the tubes is directed and reflected into the interior of said frame and mainly toward one face only thereof, so that an object to be photographed may be disposed within and adjacent said one face of said frame and exposed to said directed and reflected light from the tubes and reflectors for photographing through the lens of a camera directed into the frame through the opposite face thereof; said reflectors being at least in part adjustable about the axis of the light tubes with which they are associated and including reflector portions beyond said light tubes from said one face of said frame which are adjustable to a position in which their reflecting faces are substantially parallel to said one frame face.
Claim 2
Dependent Claim
194 words
A photographic light source comprising: a boxlike frame; sockets for mounting and electrically connecting for continuous operation a plurality of fluorescent white light tubes distributed about the inner sides of said frame and extending longitudinally of said sides; and reflectors with light diffusing reflecting surfaces mounted to extend between said sockets and about light tubes mounted therein and having a position relative to said tubes at which most of the light from the tubes is directed and reflected into the interior of said frame and mainly toward one face only thereof, so that an object to be photographed may be disposed within and adjacent said one face of said frame and exposed to said directed and reflected light from the tubes and reflectors for photographing through the lens of a camera directed into the frame through the opposite face thereof; said reflectors being at least in part adjustable about the axis of the light tubes with which they are associated and including reflector portions beyond said light tubes from said one face of said frame which are adjustable to a position in which their reflecting faces are substantially parallel to said one frame face.
Claim 3
Dependent Claim
27 words
A photographic light source according to claim 1 which includes a support for positioning an object to be photographed within the frame adjacent said one face thereof.
Claim 4
Dependent Claim
17 words
A photographic light source according to claim 2 wherein said support is removably mounted in said frame.
Claim 5
Dependent Claim
38 words
A photograhic light source according to claim 2 wherein said support closes said one face of said frame and has a flat inner surface which is light absorbent at least in the areas close to the light tubes.
Claim 6
Dependent Claim
34 words
A phographic light source according to claim 4 wherein the portions of the interior surfaces of the sides of said frame that are exposed to direct light from said light tubes are light absorbent.
Claim 7
Dependent Claim
33 words
A photographic light source according to claim 1 wherein said frame is substantially square and said sockets for mounting the fluorescent light tubes are positioned on each of the sides of said frame.
Claim 8
Dependent Claim
19 words
A photographic light source according to claim 6 wherein the walls of said frame are about twenty inches long.
Claim 9
Dependent Claim
32 words
A photographic light source according to claim 7 wherein said sockets are disposed to locate the longitudinal axes of the light tubes about three inches from said one face of said frame.
Claim 10
Dependent Claim
22 words
A photographic light source according to claim 6 which includes switch means for separately electrically connecting and disconnecting each of said tubes.
Claim 11
Dependent Claim
62 words
A photographic light source according to claim 1 wherein said reflectors include a first reflector disposed between a light tube positioned in said sockets and the adjacent side of said frame, and second and third reflectors pivoted along opposite side edges of said first reflector beyond opposite sides of said tube, one of said second and third reflectors including said reflector portion.
Claim 12
Dependent Claim
56 words
A photographic light source according to claim 10 wherein the other of said second and third reflectors is pivoted between a first position in which its reflecting surface is parallel to that of said first reflector and a second position in which its reflecting surface is inclined inwardly of said frame toward said one face thereof.
Claim 13
Dependent Claim
38 words
A photographic light source according claim 10 wherein said one of said second and third reflectors projects inwardly beyond the parallel diameter of said tube when in said position about one quarter to three quarters of an inch.
Claim 14
Dependent Claim
56 words
A photographic light source according to claim 1 which includes a plate member removably mountable across one face of said frame on which transparencies such as photographic slides may be positioned with one face thereof exposed to light from the interior of said frame and the other face thereof exposed to the exterior of said frame.
Claim 15
Dependent Claim
29 words
A photographic light source according to claim 13 wherein said plate member is translucent for viewing transparencies placed on the face thereof exposed to the exterior of said frame.
Claim 16
Dependent Claim
40 words
A photographic light source according to claim 1 which includes camera support means mountable on said frame for supporting a camera spaced outwardly of, and with the camera lens directed toward, the face of the frame opposite said one face.
Claim 17
Dependent Claim
189 words
A photographic light source comprising: a boxlike frame; sockets for mounting and electrically connecting for continuous operation a plurality of fluorescent white light tubes distributed about the inner sides of said frame and extending longitudinally of said sides; reflectors with light diffusing reflecting surfaces mounted to extend between said sockets and about light tubes mounted therein and having a position relative to said tubes at which most of the light from the tubes is directed and reflected into the interior of said frame and mainly toward one face only thereof, so that an object to be photographed may be disposed within and adjacent said one face of said frame and exposed to said directed and reflected light from the tubes and reflectors for photographing through the lens of a camera directed into the frame through the opposite face thereof; and an opaque plate member removable mountable across one face of said frame, said plate member being provided with an opening and means for retaining a photographic slide with a face thereof exposed to light from the interior of said frame through said opening for photographing of its opposite face.
