Embodiment Construction

[0021]An exemplary embodiment of the invention is shown in the drawings and described herein.

[0022]An example of a device in accordance with the invention has an assembly of channeling areas wherein the EM radiation can be internally reflected within the channeling areas. The channeling areas are constructed such that at least some of the EM radiation that enters a broad end of the channeling areas will be steered within the channeling areas to exit a narrow end of the channeling areas at a direction different to that which it entered. The broad ends of the channeling areas are assembled to form a surface that is herein termed the collection surface. EM radiation falls on the collection surface and enters the broad ends of the channeling areas. The EM radiation is reflected from the walls of the channeling areas so as to be directed to exit from the narrow end of the channeling areas. This is achieved by ensuring that at each reflection point the angle of incidence of the EM radiati...

Abstract

An electromagnetic radiation collector is provided. The electromagnetic radiation collector has a concentration chamber for collecting and concentrating electromagnetic radiation and directing it to a target, the concentration chamber having at least one inlet opening, the inlet opening having a cross-sectional area. The collector also has a channeling area having an entry end for receiving the electromagnetic radiation, the entry end having a cross-sectional area, an exit end adjacent to the inlet opening of the concentration chamber, and at least one reflective wall between the entry end and the exit end. The cross-sectional area of the inlet opening is smaller than the cross-sectional area of the entry end of the channeling area.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to electromagnetic radiation collection.[0003]2. Related Art[0004]The collection and concentration of electromagnetic (EM) radiation is well known. Radio waves are typically collected and concentrated using parabolic dishes. Solar radiation is collected and concentrated using parabolic mirrors or lenses. The former devices suffer from requiring a relatively high height-to-collection area ratio and the latter being expensive, heavy and fragile. Both these types of device also suffer from the requirement to track the source in order to function properly.BRIEF SUMMARY OF THE INVENTION[0005]The invention seeks to overcome at least some of the deficiencies in the prior art by providing an EM radiation collection and concentration device which can cover a large area, have a low profile, have no requirement to track the source and be constructed so as to be relatively light and inexpensi...
