BACKGROUND OF THE INVENTIONThe present invention is directed to the field of solar energy collecting devices. In particular, the present invention is directed to a mirror configuration that will concentrate solar energy and will efficiently produce high temperature and energy levels. The present invention is used to gather solar energy and, through a unique and novel design, to focus and intensify the solar beams. The output of the present invention can be utilized in conventional devices to heat hot water, air or other fluids and to intensely heat ores, liquids or chemical compounds to produce chemical and physical changes as well as other similar applications. For applications where interruptions in operations must be minimized, such as a plasma converter, the embodiment can include provisions for artificial light to supplement solar energy or substitute for solar energy.
SUMMARY OF INVENTIONSolar energy is collected and intensified by a system that consists of two stages. The first tracks the sun and gathers and directs the solar energy by means of an optical device, such as an assembly of paraboloidal mirrors or a fresnel lens, to a focal point which corresponds with the focal point of a paraboloidal mirror. This stage will produce parallel radiant energy of greater intensity than the solar energy collected. This parallel stream of radiant energy is transmitted to the second stage which focuses and intensifies the energy by an assembly of metal paraboloidal mirrors. The stationary second stage delivers energy to a focal point where it is utilized to heat fluids or utilized by furnaces or reactors where it produces chemical or physical changes to ore or solid and liquid chemical compounds. The heated fluids are useful to heat or air condition buildings or provide heat for manufacturing processes. The furnaces or reactors are used to provide intense heat for industrial processes. By intensifying the energy levels, materials can be converted to a plasma state without requiring vast areas of conventional reflective mirrors or lenses. By combining stages in parallel or series, the system will provide the amount of energy and the temperature needed for specific applications. The ratio of sizes and focal lengths of the optical device and paraboloidal mirror of stage 1 determine the intensity of the output from stage 1. In addition, as an element of other systems, the orientation of stage 2 can be reversed so that energy focused at a point can be the input and the output would be parallel beams of energy. This particular use would provide an extension of the systems.
Furthermore, at times when solar energy levels are too low to normally be used effectively, the system will intensify the energy and elevate the temperatures to a useful level. For installations generally requiring continuous operation, the embodiment includes sources of artificial light with automatic controls to activate and regulate the intensity of the artificial light.
The solar energy collecting system of the present invention comprises an optical device for collecting solar energy with a first focal point wherein the collecting optical device functions to intensify the solar energy by focusing the solar energy at the first focal point; a paraboloidal mirror with a second focal point for receiving the solar energy from the collecting lens at the first focal point wherein the paraboloidal mirror further intensifies the solar energy by receiving the solar energy at the second focal point and then produces and redirects a parallel stream of solar energy to an optical device with a third focal point for receiving the redirected solar energy from the first paraboloidal mirror for intensifying the solar energy and redirecting the solar energy to a third focal point whereby the solar energy can be utilized for heating purposes and a tracking system such that the collecting lens and the first paraboloidal mirror will rotate during daylight hours to follow the sun and optimize the collection of solar energy.
The present invention will now be described in terms of the presently preferred embodiment thereof. Those of ordinary skill in the art will recognize that many obvious modifications may be made thereto without departing from the spirit or scope of the present invention.
The solar collecting system 10 of the present invention is illustrated in
The solar tracking system 14 is also illustrated in
The collecting optical device 12 and paraboloidal mirror 24 focuses the solar energy received there through onto the parabolic intensifying mirrors 25. The second stage parabolic reflecting mirrors 25 are further described below in connection with
The intensifying mirror assembly 25 shown in
The intensifying mirrors 28 and dimple mirrors 32 may be constructed of plastic with a reflective film on the interior in the case of moderate temperature applications. The range of temperatures at the point of focus can reach 2000° F. For higher temperature applications in the range of 30,000° F. at the point of focus, the entire assembly 25 should be comprised of chromium plated stainless steel or other similar materials to withstand the operating temperatures they will be subjected to, in the range of 1,000° F. to 1,100° F. If necessary, fans may be used to circulate cooling air on any mirror or through the cylindrical assembly. Any optical device with parabolic or paraboloidal operational characteristics may be substituted for the corresponding parabolic or paraboloidal mirrors.
An alternate version of stage 2 is illustrated in
Energy from source 38 flows along three (3) paths: (a) to Fresnel lens 37 to intensifying lens 25; or (b) to Fresnel lens 39 to flat mirrors 41 and 42 to intensifying mirror 25; or (c) to paraboloidal mirror 43 to intensifying mirror 25. The output of source 38 is regulated by intensity detector 51 via control circuitry 52 and regulator 45.
Those of ordinary skill in the art will recognize that the foregoing are merely embodiments of the present invention and many obvious modifications may be made thereto without departing from the spirit or scope of the present invention as set forth in the appended claims.
