Abstract

Abstract The invention is a device which receives radiation from a point source, from the sun, or from other means, said radiation being received on the surface of a mirrored paraboloid of revolution which is tracking the point source, though the source may be stationary, and reflects the radiation to the mirrored surface of a confocal hyperboloid of revolution whose shape is dependent on the distance to the desired second focus. The hyperboloid reflects radiation of high intensity to the second focus, where the flux is intensified, using a conical mirrored surface or a compound parabolic concentrator, to a flux intensity approaching the surface flux intensity of the sun. The radiation input to the device may also be from an array of point or distributed sources, such as from an array of lasers.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 69 words
An omni-directional compound paraboloid-hyperboloid radiation device, comprising: a paraboloid having an internal reflecting surface for tracking a source of radiation; and a hyperboloid having an external reflecting surface, said hyperboloid being movably mounted with respect to said paraboloid reflecting surface for redirecting the radiation reflected from said internal reflecting surface of said paraboloid to a location remote from said paraboloid and concentrating the reflected radiation at said remote location.
Claim 2
Dependent Claim 69 words
An omni-directional compound paraboloid-hyperboloid radiation device, comprising: a paraboloid having an internal reflecting surface for tracking a source of radiation; and a hyperboloid having an external reflecting surface, said hyperboloid being movably mounted with respect to said paraboloid reflecting surface for redirecting the radiation reflected from said internal reflecting surface of said paraboloid to a location remote from said paraboloid and concentrating the reflected radiation at said remote location.
Claim 3
Dependent Claim 33 words
The radiation device as recited in claim 1, and additionally, a concentrator having an internal reflective surface, suitably mounted at the focus of the reflected radiation from said external surface of said hyperboloid.
Claim 4
Dependent Claim 20 words
The radiation device as recited in claim 1, and means for mounting said paraboloid for tracking a source of radiation.
Claim 5
Dependent Claim 19 words
The radiation device as recited in claim 1, and additionally means for cooling the reflective surface of said hyperboloid.
Claim 6
Dependent Claim 19 words
The radiation device as recited in claim 2, and means for cooling the internal reflective surface of said concentrator.
Claim 7
Dependent Claim 18 words
The radiation device as recited in claim 1, wherein said paraboloid and said hyperboloid have a common focus.
Claim 8
Dependent Claim 20 words
The radiation device as recited in claim 1, wherein said source of radiation is an array of sources of radiation.
Claim 9
Dependent Claim 20 words
The radiation device as recited in claim 7, wherein said array of sources of radiation is an array of lasers.
Claim 10
Dependent Claim 23 words
The radiation device as recited in claim 2, and additionally, means for cooling the reflective surfaces of said paraboloid hyperboloid, and said concentrator.
Claim 11
Dependent Claim 20 words
The radiation device as recited in claim 9, and means for mounting said paraboloid for tracking a source of radiation.
