Problems solved by technology
Among them, No. 1146203 uses a single fish-eye lens (fish-eyelens) to collect the light source. Although this does not require any power assistance, the light collection effect is poor
In addition, No. 2239505 uses 3-branch type lighting units, each of which is fixed in three directions such as east, west, and south, and uses these three lighting units to collect light separately, but this is not only costly High and the light collection effect is not ideal

Embodiment Construction
[0033] Please also see figure 2 ,and image 3 , figure 2 is a perspective view of a preferred embodiment of the present invention, and image 3 It is a sectional view of a preferred embodiment of the present invention. The figure shows a coaxially arranged light-collecting device, which includes a second light-collecting lens 1, which is a biconvex lens in this embodiment. There is also a light-collecting cover 2 with a curved surface similar to an umbrella shape, which is arranged above the second light-collecting lens 1 . The surface of the collecting cover 2 is provided with a plurality of openings 201 and includes a plurality of first collecting lenses 211 , and the plurality of first collecting lenses 211 are respectively embedded in the plurality of openings 201 . Among them, in this embodiment, the multiple first light collecting lenses of the light collecting cover adopt two specifications, and the biconvex lenses with larger diameters are the main ones. In the ...

The invention discloses a coaxially arranged light collecting device, which comprises a second light collecting lens, a light collecting shade, and a light distributor, wherein the light collecting shade is arranged above the second light collecting lens, and comprises a plurality of holes and a plurality of first light collecting lenses; the plurality of first light collecting lenses are embedded and fixed in the plurality of holes, and are not arranged in the same plane; moreover, the light distributor is arranged under the second light collecting lens, and comprises a concave lens and a plurality of optical fibers, wherein the concave lens and the second light collecting lens are arranged in the same axle wire, and the optical fibers are positioned on the side of the lower concave surface of the concave lens. Therefore, the light collecting device can provide high-quality natural light, has the advantages of good light collecting effect, simple structure and low cost, and completely needs no consumption of electrical power or energy.
Description
technical field [0001] The invention relates to a coaxially arranged light collecting device, especially a light collecting device suitable for daylight lighting equipment. Background technique [0002] With the increasing severity of the greenhouse effect and the implementation of the Kyoto Protocol, all countries are committed to reducing carbon dioxide emissions. At present, among energy alternatives for reducing carbon dioxide emissions, solar energy is the most widely used. Furthermore, lighting is one of the indispensable elements in human life, and sunlight has provided the best source of human lighting since ancient times. In the past, the means of using sunlight indoors was nothing more than using skylights, windows, or installing lighting covers on the roof. However, these traditional methods not only have limited lighting levels, but also have great restrictions on lighting locations. [0003] Therefore, an off-site light source system that can save energy and d...
