Description
Technical field
The utility model belongs to application of solar, the daylighting and the lighting device that particularly utilize optical fiber that the conductive performance of sunshine light is designed.
Background technology
Because more existing problems and contradiction in the architectural design, now, many interior of buildings all need to turn on light by day and obtain rational illumination.Quite a large amount of buildings is as: the teaching building of large-area office buildings, middle and primary schools, some are badly in need of the big old house of the little depth of the standard width of a room in an old-style house transformed, black room, basement or the like, solve the problem of daylighting when all needing by day with artificial lighting.In addition, the occasion that some are special as operation under underwater operation, dangerous material Production Regional, the mine etc., obviously causes danger easily with electric lighting, and when historical relic or some arts work were thrown light on, directly artificial lighting also can cause damage to these valuables.At this time, adopt optical fibre illumination just more suitable.
No matter at home or abroad, the research of adopting optical fiber to carry out collection of sunshine light and transmission has begun already, but majority is not very desirable as a result.Because light propagates in strict accordance with the optics route, day light direction each in the every day at all seasons is constantly all in the conversion that does not stop, and the light that incides optical fiber head also must satisfy fiber optic materials the incidence angle that can allow.Therefore, the direction of sunshine incident not being furtherd investigate is the direct conduction that at all can't realize sunshine.
In the existing patent of China, a patent that is entitled as " solar fibre-optical lighting device " (application number is 97247820) that relates to this field is arranged, the technical scheme of this patent disclosure is as shown in Figure 1: this device is reflexed to natural daylight in the optical fiber 3 by optically focused curved surface 1, reach again in the camera bellows 4 as light source, convex lens 9 with convergence of rays to optical fiber 5, reach any need illumination place luminous lighting by optical fiber 5, and utilize night bulb as the light emitting source in the camera bellows 4.
This patent has four very large leaks:
1. the variation that do not stop of the direction of sunlight is singly adopted an optically focused curved surface, and it is impossible allowing light reflex to optical fiber head by reflection way.Because parallel incident light direction difference, concave mirror can not all converge to reverberation on the focus, but can converge the variation of direction according to the day light direction, and the scope of this variation can not guarantee to converge to fully optical fiber head very greatly;
2. optically focused curved surface 1 is " be installed in the place of roof or outdoor solar ray energy direct irradiation, inner surface is to be paved into by many facet mirrors ... ".This way is feasible for the heat of concentrating solar energy, and because light is very harsh to the required precision of reflecting surface, the height polymerization light that reaches light with the facet mirror is difficult to realize;
3. " the layer overlay plastic foil burns out optical fiber head with anti glare anti static coatings on the facet mirror ".This rule of doing is mistake on a kind of understanding fully.Reflecting surface should keep good reflective function, so just the light of incident can be injected optical fiber as much as possible, and does not just produce very big light loss consumption at the incident end.And adopt " one deck plastics ", except reducing reflecting properties, can not prevent " high light burns out optical fiber head " fully.
4. mid portion adopts black box, with this a kind of especially saying of not studying fully of light " reach in the camera bellows 4 as light source, convex lens 9 with convergence of rays to optical fiber 5 ".Though in specification, stated " plate mercury on camera bellows 4 inner surfaces to reduce the loss of light, the light planoconvex lens 9 that light emitting source sends is assembled the end to optical fiber head 5a, reaches optical fiber head 5b end luminous lighting by optical fiber 5 again ".But in fact, when optical fiber is transmitted to light in the camera bellows, because the space in the middle of the camera bellows must hold bulb wherein, and also be directional light anything but from the light of optical fiber end outgoing, therefore, the repeatedly reflection of light in big like this space can not guarantee can be injected in the other one section optical fiber head after the scioptics, even reached the light on that optical fiber head, also might can't incide in the middle of the following optical fiber because having surpassed the incidence angle that optical fiber end requires (this numerical value according to different fiber optic materials and different).Here almost can lose whole luminous energy of incident.
Lack the patent of considering compared with top this, fairly perfect at last by the test that more external physics Institute carry out.The mode of collection that they adopt and propagation daylight, as shown in Figure 2.Whole device is made up of with reflector segment 24 receiver 21 of following the sunshine direction, optical fiber 23.Sunlight is by lens on the receiver 21 of following the sunshine direction or Fresnel Lenses 22, with the end 23a of light-ray condensing to optical fiber or fibre bundle 23.And then be transmitted on its other end 23b by optical fiber 23, light is transmitted to the place that needs illumination by reflection shield 24.In these researchs, in order to obtain most sunlight incident, receiver 21 will rotate with the sun according to the beam intensity ratio of all directions.Utilize the optically focused principle of lens 22, light directly is aggregated on the optical fiber head.In this case, require receiver 21 to resemble that the accurate and then sun rotates the sunflower.
Though this way the test on obtained certain success, can't promote and come, this be because of:
1. the Jing Mi equipment of following the sun becomes the means of this problem of solution day angle of light variation the most basic in this design, but this expensive thing makes whole device improve the cost of package unit greatly, and it so just can accomplish enough sensitivities to required precision also unusual height.
2. this matching requirements total of rotating along with the sun is very firm, so just might have durable performance.But this has also brought a big difficult problem to Unit Installation.Guarantee that this device can both be firm under different weathers and wind-force, make constructional difficulties very big.
Because the existing problem of top various types of like device, the idea that sunshine is directly imported can't put it over and use always.
