Abstract
A lighting device comprising a plurality of overlapping leaves hingedly attached to a base that can be manipulated to control the size of an opening through which light from a light source passes, and thereby the size and intensity of the light. In some embodiments the device includes an off-center lighting source whereby a light beam is emitted at an angle to an axis passing through the center of the opening formed by the leaves.
Claims19
A lighting device for use in combination with a light source, the device comprising:
- a plurality of overlapping concave leaves defining an opening through which light from the light source can be emitted;
- and
- a base at which said leaves are hingedly attached,
- whereby movement of one or more of the plurality of overlapping leaves produces a corresponding movement, opening or closing, of the remainder of the leaves, whereby the opening defined by the leaves is enlargeable and can be contracted and wherein at least said base or one of said plurality of overlapping concave leaves comprises perforations for controlling the emitted light by allowing light to radiate there-through.
1 more element
A lighting fixture comprising:
- a light source;
- a plurality of concave overlapping leaves defining an opening through which light from the light source can be emitted;
- and
- a base at which said leaves are hingedly attached, at least said base or one of said plurality of overlapping concave leaves comprising perforations for controlling the emitted light by allowing light to radiate there-through.
1 more element
A method of controlling the size or intensity of light emitted from a light source comprising:
- moving at least one of a plurality of overlapping concave leaves hingedly arranged on a base whereby an opening defined by the leaves is enlargeable and can be contracted and at least said base or one of said plurality of overlapping concave leaves comprises perforations for controlling the emitted light by allowing light to radiate there-through.
