Detailed description of the invention
In order to be more fully understood that this utility model, explain content of the present utility model further below in conjunction with embodiment, but
Content of the present utility model is not limited solely to the following examples.
As shown in Figure 1, 2, a kind of optical fiber-concentrator, multiple fiber units 1 connect and compose tree, each optical fiber list
Unit includes at least two receiving terminal 11 and an outfan 12, and optical fiber-concentrator includes multilamellar from bottom to top, in described adjacent layer
The outfan 12 of upper strata fiber unit is connected with a receiving terminal 11 of lower floor's adjacent fiber unit, fiber unit 1 from bottom to top
Quantity successively increases；The receiving terminal of the multiple fiber unit of the described the superiors converges downwards after receiving sunlight, transmits, finally
Outfan injection through orlop fiber unit.
Fiber unit is made fork-shaped structure by this utility model, and multiple fiber units 1 are assembled into tree crown shape
Optical fiber-concentrator, the multiple fiber unit of the superiors 1 is accepted nature light, is then successively converged by fiber unit structure, finally converge
Gather in undermost trunk optical fiber unit 1, it is achieved large-area natural light is converged in single or several optical fiber,
And by fiber-optic transfer to indoor, it is achieved natural light room lighting, reach the effect of high-effective concentration.
In the present embodiment, described each fiber unit 1 includes two receiving terminals 11 and a light output end 12, Y-shaped
Structure.
In the present embodiment, described fiber unit 1 quantity successively increases in geometry level, wherein orlop only one of which optical fiber
Unit 1.By increasing the superiors' fiber unit quantity, increase optical fiber-concentrator and receive the area of sunlight, and orlop is only
One ejecting end, then improve the effect of optically focused.
In the present embodiment, connected by optical cement between described adjacent fiber unit, it is not necessary to coupling, easy to operate, effect
Rate is high.By optical cement, the adjacent face precision of two fiber units is docked, make the luminous energy of upper strata fiber unit output
Amount can be coupled in lower floor's fiber unit to greatest extent.
Single fiber unit receiving terminal angle of incidence of sunlight degree is as shown in table 1 with the relation of spotlight effect.
Table 1 incident angle and the relation of spotlight effect
| Incident angle | 0° | 5° | 10° | 15° | 20° | 25° | 30° |
| Spotlight effect | 98% | 93.07% | 91.01% | 82.02% | 77.59% | 66.75% | 66.07% |
| Angle | 35° | 40° | 45° | 50° | 55° | 60° | 65° |
| Spotlight effect | 50.84% | 41.77% | 26.32% | 22.16% | 22.34% | 20.71% | 18.50% |
From table 1 it follows that along with the increase of incident illumination Yu receiving terminal angle, under single fiber unit spotlight effect
Fall, when 35 °, still has the incident optical energy of about 50% by optically focused, it is not necessary to requiring that fiber end face is directed at sunlight, remaining to realization has
Effect optically focused.In the case of without sun direct projection, it is also possible to collect ambient light, it is achieved natural lighting.Optical analog shows, is dissipating
Penetrating under optical condition, the light gathering efficiency of the luminous flux inciding fiber end face can reach 67.8%.Therefore in the present embodiment, optical fiber
Multiple fiber units on condenser upper strata are arranged into dome shape, and in the middle of one day, no matter how the sun offsets, always some light
The receiving terminal of fine unit is vertical with sunlight, it is achieved the luminous flux of condenser changed the slowest in one day, improved at one day
The stability of central natural lighting.Without arranging heliostat, it is not necessary to follow the tracks of the sun, sunray direction changes its optically focused
Influential effect is little.
This utility model does not does illustrate be prior art or can be realized by prior art, Er Qieben
It is embodied as case described in utility model and is only preferable case study on implementation of the present utility model, be not used for limiting this practicality
Novel practical range.The most all equivalence changes made according to the content of this utility model claim and modification, all should make
For technology category of the present utility model.
