ABSTRACT:
A light source usable as a projector for photography, motion pictures, television, or as a light panel, or as a lighting apparatus. This light source comprises a polyhedric housing constituted by a rectangular back 2, two trapezoidal lateral sides 4 inclined to the back 2, two limiting frontal faces 5 closed by translucent sheets, and one central face 10 for accessories such as grid-spots, filters, etc. The back 2 has an opening 3 for a light source, and interior 54 and exterior 80 reflectors are articulated on the back 2. This device makes it possible to vary the characteristics of the light source, notably its intensity, the angle lit, its color saturation, the contrast, the shadow sharpness, the reflections, etc., so as to obtain the desired effects. It is light in weight and inexpensive.
