ABSTRACT:
A highly controllable way to light target areas includes a primary reflector which generates a defined primary beam in association with a light source. The primary beam, or at least a portion of the primary beam, is directed onto a secondary reflector which generates a secondary beam to the target space. Other options, enhancements, alternatives, and features are possibly utilized in the principles of the present invention whereby a primary light source is reflected off of a secondary reflector means. The secondary reflector can be configured in any number of contours, shapes, specularities, or other characteristics to alter and control the characteristics of the secondary beam.
Various options, alternatives, and features are possible with the invention. For example, a plurality of light sources and primary reflectors can be used with one secondary reflector. The surface of the secondary reflector can be corrugated to have alternating segments to direct light in different directions. A combination of light source, primary reflector, and secondary reflector can also be positioned on a moveable base. A plurality of secondary reflectors and light sources and primary reflectors can be positioned on one moveable base and can be oriented in different configurations for different lighting effects.
