Abstract
A photography light for providing fill illumination includes a first reflector having planar sides and an opening in a rear portion thereof, a second reflector lying within the first reflector and overlying the opening therein. The second reflector forming light compensating channels with the sides of the first reflector and includes at least one aperture in a rear surface thereof through which lamps may be variably positioned. The light compensating channels allow a portion of the light blocked by the backs of the reflectors when the lamps are in a retracted position, to pass to the front portion of the reflectors to be reflected into the photographing field thereby smoothing the illumination therein.
Claims10
A photography light comprising:
- (a) a main reflector having an upper surface, a lower surface, and two side surfaces, said surfaces being made reflective on an inner portion of said main reflector, said main reflector also being formed with an opening in a rear portion thereof;
- (b) a secondary reflector also having an upper surface, a lower surface, and two side surfaces, said secondary reflector further having a rear surface having aperture means formed therein, said surfaces being made reflective on an inner portion of said secondary reflector, said secondary reflector being positioned within and spaced from said opening in said main reflector such that said aperture means in said secondary reflector overlies said opening and the surfaces of said secondary reflector form light compensating channels with the respective surfaces of said main reflector;
- (c) illuminating means positionable within said aperture means for illuminating a photographing field, said illuminating means being elongated along an axis of said aperture means;
- and
- (d) means for positioning said illuminating means along said axis of said aperture means in a first position, in which said illuminating means is fully inserted in said aperture means and all the illumination therefrom is available for illuminating said photographing field, and in a second position, in which said illuminating means is fully retracted from said aperture means and only a portion of the illumination therefrom passes through said aperture means and said light compensating channels, a remaining portion of said illumination being blocked by a back surface of said main and secondary reflectors.
