Abstract
A sunlight guiding device comprises a light condensation unit used for condensing sunlight, inner wall total-reflection straight tubes used for transmitting sunlight, corner reflection units connected with the multiple non-directly-connected total-reflection straight tubes and used for changing the transmission direction of a light path, and an illumination unit used for indoor illumination. The multiple total-reflection straight tubes and the corner reflection units are connected to form a sunlight transmission channel from outdoor to indoor. The light condensation unit is connected to the outdoor end of the sunlight transmission channel. The illumination unit is connected to the indoor end of the sunlight transmission channel. The sunlight guiding device has the beneficial effect that the total-reflection straight tubes of a tubular structure and the corner reflection units are adopted to form the sunlight transmission channel and replace traditional silica fibers high in cost to achieve the sunlight direct guiding-in function. Meanwhile, the transmission power is higher as a plastic optical fiber low in cost is adopted. The sunlight guiding device is simple in structure and lower in later maintenance cost.
Description
Technical field
The invention belongs to technical field of new energies, relate to the application of sunshine in illumination, be specifically related to a kind of sunshine guiding device.
Background technology
Well-known solar energy is a kind of inexhaustible clean energy resource, is the new forms of energy getting a good chance of replacing fossil fuel 21 century.The various technology of solar energy that utilizes continues to bring out, wherein sun light lighting is exactly an important technology of Application of Solar Energy, concrete scheme under the sun, collects sunshine by a device, then sunshine imported indoor by guiding device (as optical fiber, light conducting cylinder etc.) and throw light on.Eliminate transfer process complicated in the middle of photocell compared with being thrown light on by electrical energy drive with after solar electrical energy generation, equipment is simpler again, is easier to promote.But the sunshine leading-in technique that sun light lighting adopts at present but also exists the high shortcoming of cost, main cause is that the silica fibre cost of manufacture transmitting sunshine is high, the price of 1 meter is about hundreds of unit, cause holistic cost high, another kind of lower-cost scheme is plastic optical fiber, but plastic optical fiber but exists temperature tolerance difference, power bears the shortcomings such as difference.Therefore at present the main development direction of sunshine leading-in technique is exactly how by cheap fiber optic applications to sunshine import system or the optical fiber of the technical substitution costliness finding cost lower.
Summary of the invention
The object of the invention is directly to import the deficiencies such as the indoor technology use silica fibre cost for throwing light on is high, plastic optical fiber power limited to solve existing sunshine, proposing a kind of sunshine guiding device.
Technical scheme of the present invention is: a kind of sunshine guiding device, it is characterized in that, comprising the light focusing unit for converging sunshine, being totally reflected straight tube for the inwall of transfer sun light, connecting multiple indirectly connected total reflection straight tube for changing the corner reflector element in optic path direction and the lighting unit for room lighting; Multiple total reflection straight tube and corner reflector element connect to form from outdoor to indoor sunshine transmission channel; Light focusing unit is connected to the outdoor end of sunshine transmission channel, and lighting unit is connected to the indoor end of sunshine transmission channel.
Further, described light focusing unit is Fresnel Lenses.
Further, lighting unit is convex lens, and wherein the one side of convex lens is plane, and another side is convex spherical.
Further, described corner reflector element has multiple passage, for being separated into multiple spot illumination by after the sunshine light splitting of outdoor convergence by multiple passage.
Beneficial effect of the present invention: sunshine gatherer of the present invention adopts total reflection straight tube and the corner reflector element composition sunshine transmission channel of tubular structure, and the silica fibre substituting traditional cost intensive achieves the direct import feature of sunshine.Simultaneously higher relative to adopting the plastic optical fiber conducted power of low cost.And access node structure is simple, later maintenance cost is lower.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is sunshine guiding device structure principle chart of the present invention.
In figure: 1, light focusing unit, 2, inwall total reflection straight tube, 3, corner reflector element, 4, lighting unit.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further elaborated.
As shown in Figure 1, a kind of sunshine guiding device of the present embodiment, comprising the light focusing unit 1 for converging sunshine, being totally reflected straight tube 2 for the inwall of transfer sun light, connecting multiple indirectly connected total reflection straight tube for changing the corner reflector element 3 in optic path direction and the lighting unit 4 for room lighting; Multiple total reflection straight tube and corner reflector element connect to form from outdoor to indoor sunshine transmission channel; Light focusing unit is connected to the outdoor end of sunshine transmission channel, and lighting unit is connected to the indoor end of sunshine transmission channel.
One of below for the present invention is based on the preferred version of above-described embodiment:, above-mentioned light focusing unit is Fresnel Lenses, makes optically focused scope larger; Two, lighting unit is convex lens, and wherein the one side of convex lens is plane, and another side is convex spherical, room lighting is more disperseed and evenly; Three, described corner reflector element has multiple passage, for by after the sunshine light splitting of outdoor convergence by multiple passage be separated into multiple spot illumination, be particularly suitable for the integrated system as the scattered illumination such as field energy lighting for large space or office building that lowly stop.
Those of ordinary skill in the art will appreciate that, embodiment described here is to help reader understanding's principle of the present invention, should be understood to that protection scope of the present invention is not limited to so special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combination of not departing from essence of the present invention according to these technology enlightenment disclosed by the invention, and these distortion and combination are still in protection scope of the present invention.
