Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
157 words
In combination with a light source and with a camera having a lens, a lighting device comprising: an opaque reflector of truncated shape having a base wall formed with an opening and a side wall flaring outwardly from said base wall and formed with a pair of offset lightpassing windows; said reflector with said opening aligned with said lens, whereby said camera can take a picture through said opening; means for securing said light source outside said reflector at one of said windows in a position wherein light emitted by said source is reflected by the interior of said reflector at an object viewable by said camera through said opening, said light source being out of line with said lens in said position; and means including a guide on said reflector and an opaque slide displaceable along said guide across a one of said windows for varying the amount of light passing through the thus equipped window.
Claim 2
Dependent Claim
