Abstract
The utility model discloses a sunlight guide device. The sunlight guide device comprises a light gathering unit for gathering sunlight, an inner wall total-reflection straight barrel for conducting sunlight, a corner reflection unit connected with a plurality of indirectly connected total-reflection straight barrels for changing the light path transmission direction, and an illumination unit for indoor illumination; the total-reflection straight barrels are connected with the corner reflection unit to form a sunlight transmission passage from the outside to the inside; the light gathering unit is connected with the outdoor end of the sunlight transmission passage, and the illumination unit is connected with the indoor end of the sunlight transmission passage. According to the sunlight guide device, barrel-shaped total-reflection straight barrels and the corner reflection unit make up the sunlight transmission passage, and the sunlight guide device replaces the traditional expensive silica fiber to directly guide the sunlight. Compared with the plastic optical fiber with low cost, the conduction power is higher. The sunlight guide device is simple in structure and lower in post maintenance cost.
Description
Technical field
The utility model belongs to technical field of new energies, relates to the application of sunshine aspect illumination, is 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 that get a good chance of replacing fossil fuel 21 century.The various technology of utilizing solar energy continue to bring out, wherein sun light lighting is exactly an important technology of Application of Solar Energy, concrete scheme is under the sun, to collect sunshine by a device, then sunshine is imported to indoor illumination by guiding device (as optical fiber, light conducting cylinder etc.).With after solar electrical energy generation, drive and saved transfer process complicated in the middle of photocell compared with illumination by electric energy again, equipment is simpler, is easier to promote.But the sunshine leading-in technique that sun light lighting adopts at present but exists the shortcoming that cost is high, the silica fibre cost of manufacture that main cause is to transmit sunshine is high, the price of 1 meter is in hundreds of unit left and right, cause holistic cost high, another kind of lower-cost scheme is plastic optical fiber, but plastic optical fiber but exists temperature tolerance poor, power bears the shortcomings such as poor.Therefore at present the main development direction of sunshine leading-in technique be exactly how by cheap fiber optic applications in sunshine import system or find the technology that cost is lower to substitute expensive optical fiber.
Summary of the invention
The purpose of this utility model is directly to import the deficiencies such as indoor, plastic optical fiber power limited high for the utilization silica fibre cost that throws light in order to solve existing sunshine, has proposed a kind of sunshine guiding device.
The technical solution of the utility model is: a kind of sunshine guiding device, it is characterized in that, comprise light focusing unit for converging sunshine, for the inwall total reflection straight tube of transfer sun light, connect multiple indirectly connected total reflection straight tubes for changing the corner reflector element of optic path direction and the lighting unit for room lighting; Multiple total reflection straight tubes and corner reflector element connect to form from outdoor to indoor sunshine transmission channel; Light focusing unit is connected in the outdoor end of sunshine transmission channel, and lighting unit is connected in 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 protruding sphere.
Further, described corner reflector element has multiple passages, for being separated into multiple spot illumination by multiple passages after outdoor sunshine light splitting of converging.
The beneficial effects of the utility model: sunshine gatherer of the present utility model adopts total reflection straight tube and the corner reflector element composition sunshine transmission channel of tubular structure, and the silica fibre that substitutes traditional cost costliness has been realized the direct import feature of sunshine.With respect to adopting, plastic optical fiber conducted power is higher cheaply simultaneously.And connecting structure is simple, later maintenance cost is lower.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is sunshine guiding device structure principle chart of the present utility model.
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 utility model is further elaborated.
As shown in Figure 1, a kind of sunshine guiding device of the present embodiment, comprise light focusing unit 1 for converging sunshine, for the inwall total reflection straight tube 2 of transfer sun light, connect multiple indirectly connected total reflection straight tubes for changing the corner reflector element 3 of optic path direction and the lighting unit 4 for room lighting; Multiple total reflection straight tubes and corner reflector element connect to form from outdoor to indoor sunshine transmission channel; Light focusing unit is connected in the outdoor end of sunshine transmission channel, and lighting unit is connected in the indoor end of sunshine transmission channel.
One of be below the preferred version of the utility model based on above-described embodiment:, above-mentioned light focusing unit is Fresnel Lenses, makes optically focused scope larger; Two, lighting unit is convex lens, wherein the one side of convex lens is plane, another side is protruding sphere, room lighting is more disperseed and evenly; Three, described corner reflector element has multiple passages, for will be after outdoor sunshine light splitting of converging being separated into multiple spot illumination by multiple passages, is particularly suitable for disperseing as low parking field energy lighting for large space or office building etc. the integrated system of illumination.
Those of ordinary skill in the art will appreciate that, embodiment described here is in order to help reader understanding's principle of the present utility model, should be understood to that protection domain of the present utility model is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combinations that do not depart from the utility model essence according to disclosed these technology enlightenments of the utility model, and these distortion and combination are still in protection domain of the present utility model.
