Abstract
A reflector employs shapes that transfer light and sound emission from sources to planes or volumes in an efficient and controlled manner. Reflector troughs employ shaped ends that increase the efficiency of utilizing output from sources, improve uniformity and project light outside the footprint of the reflector. A slanted trough reflector projects light out one or both ends of the trough outside the footprint of the reflector. Axi-symmetric and linear-symmetric reflectors provide directionality for specific applications. Sources that erode are enclosed by shaped reflectors to maintain directionality as the source erodes.
Claims22
A combined reflector and source system for directing and projecting emissions from the source to a surface or into a volume, the system comprising:
- a first reflective surface defining a first geometric shape,
- a second reflective surface defining a second geometrical surface,
- wherein the reflector system defines a footprint, and
- wherein the first and the second reflective surfaces reflect the emissions from the source, and further wherein the relative locations of the first, the second reflective surfaces, and the source combine to control the emission distribution on the surface or within the volume outside the footprint.
