Abstract
A lighting system includes a bright bulb installed in front of a variable reflector assembly comprising a plurality of leaves. The leaves have some overlap and are pivotally attached near the base of the bulb, so that they can be collapsed inward or expanded outward in tandem by a mechanism. A baffle and light shield enclose and protect the bulb, and result in controllable and variable indirect lighting from the bulb.
Claims16
An adjustable reflective lighting system comprising:
- a lighting element having a base and extending forward from the base;
- a reflective element including
- a plurality of curved leaves forming a generally parabolic shape;
- the leaves pivotally attached near the base, such that the leaves can open outward from the lighting element and close inward toward the lighting element;
- wherein each leaf overlaps a neighbor, such that the leaves collapse inward and open outward in tandem;
- and
- a control mechanism for selectively pushing at least some of the leaves forward to close the reflective element inward toward the lighting element and for selectively pulling the leaves backward to open them away from the lighting element.

The method of generating and adjusting light for shining on a photographic subject, the method comprising the steps of:
- providing a lighting element having a base and extending forward from the base;
- providing a reflective element including
- a plurality of curved leaves forming a generally parabolic shape;
- the leaves pivotally attached near the base, such that the leaves can open outward from the lighting element and close inward toward the lighting element;
- wherein each leaf overlaps a neighbor, such that the leaves collapse inward and open outward in tandem;
- and
- adjusting the lighting effect by either
- selectively pushing at least some of the leaves forward to close the reflective element inward toward the lighting element;
- or
- selectively pulling at least some of the leaves backward to open them away from the lighting element.
