Abstract

The utility model provides solar illuminating system, is characterised in that primarily of Fresnel Lenses, support, light harvesting block, optical fiber, and astigmatism block forms.During use, Fresnel Lenses is just to sunlight, and sunlight focuses on light harvesting block after Fresnel Lenses.Fiber connection light harvesting block and astigmatism block three form the path of light, and the sunlight after focusing enters astigmatism block by incidence end.Light is injected astigmatism chamber from exit facet, and irradiate on the reflecting surface, some sunlight is reflected on exiting surface.Finally penetrate astigmatism block.Remaining light penetrates from exit end, continues along spread fiber, through multiple astigmatism block.And by ultraviolet ray filter elimination ultraviolet harmful components wherein.The beneficial effects of the utility model are, utilize solar energy to throw light on, and realize zero energy consumption, the object of environmental protection, and good illumination effect, and without UV-shares, layout is not by the restriction of sunniness direction.

Description

Solar illuminating system

Technical field

The utility model relates to lighting technical field, specifically solar illuminating system.

Background technology

Students' dormitory large contingent, keep intensity of illumination for student physical and mental health extremely important.But because dorm room is intensive, even sunny by day when, often have more dormitory to there is the inadequate problem of illumination.Even some dormitory needs round-the-clock bright light could meet the needs of illumination, and this just causes larger waste of energy.From illuminating effect, the effect of lamp lighting is worse than the illuminating effect of natural daylight far away.

Utility model content

For the technical problem mentioned in prior art and technical need, the utility model provides solar illuminating system.

The utility model is achieved in the following ways:

Solar illuminating system, is characterized in that primarily of Fresnel Lenses (1), support (2), light harvesting block (3), optical fiber (4), and astigmatism block (5) forms.

Light harvesting block (3) is fixed on the focal position of Fresnel Lenses (1) by support (2); Optical fiber (4) connects light harvesting block (3) and astigmatism block (5), and three is the medium of light transmittance more than 95%, and three forms the path of light; It is leg-of-mutton astigmatism chamber (9) that astigmatism block (5) comprises longitudinal section, and astigmatism chamber (9) are surrounded by exit facet (8), reflecting surface (10) and exiting surface (12), and three is minute surface; The axis of optical fiber (4) passes the geometric center of exit facet (8).

During use, Fresnel Lenses (1) is just to sunlight, and sunlight focuses on light harvesting block (3) after Fresnel Lenses (1).Optical fiber (4) connection light harvesting block (3) and astigmatism block (5) three form the path of light, and the sunlight after focusing enters astigmatism block (5) by incidence end (6).

Light is injected astigmatism chamber (9) from exit facet (8), is radiated on reflecting surface (10), and some sunlight is reflected on exiting surface (12).Finally penetrate astigmatism block (5).Remaining light, from exit end (7) injection, continues to propagate, through multiple astigmatism block (5) along optical fiber (4).And by ultraviolet ray filter (11) elimination ultraviolet harmful components wherein.

The beneficial effects of the utility model are, utilize solar energy to throw light on, and realize zero energy consumption, the object of environmental protection, and good illumination effect, and without UV-shares, layout is not by the restriction of sunniness direction.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is front view of the present utility model.

Wherein:

1-Fresnel Lenses, 2-support, 3-light harvesting block, 4-optical fiber, 5-astigmatism block, 6-incidence end, 7-exit end, 8-exit facet, 9-astigmatism chamber, 10-reflecting surface, 11-ultraviolet ray filter, 12-exiting surface.

Detailed description of the invention

Below in conjunction with concrete accompanying drawing, exemplary embodiment of the present utility model is described.

As shown in Figure 1:

Also comprise ultraviolet ray filter (11), ultraviolet ray filter (11) is arranged in astigmatism chamber (9), covers on exiting surface (12).The area of exit facet (8) is greater than the cross-sectional area of optical fiber (4)

The beneficial effects of the utility model are, utilize solar energy to throw light on, and realize zero energy consumption, the object of environmental protection, and good illumination effect, and without UV-shares, layout is not by the restriction of sunniness direction

In addition, embodiment of the present utility model is the example representing content of the present utility model, can combine with other known technology further, also can omit a part etc. and carry out changing forming in the scope not departing from purport of the present utility model.

Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
