Description

A lighting system for light pipes

[technical field]

The utility model relates to indoor lighting, in particular to a lighting system for a light guide tube.

[Background technique]

The light pipe lighting system can economically and efficiently transmit natural light to indoor spaces that traditional skylights and windows cannot reach at all, because it greatly reduces people's electricity demand and closely connects people with the outdoor environment, it has become a cost-effective, The ideal solution for energy-efficient and ecological interior lighting design.

At present, most of the light guide systems use skylight collectors, which are mainly used in the atrium and top floors of office buildings and hotel buildings; the roofs of terminal buildings and waiting buildings of airports and stations; the transparent roofs of botanical garden greenhouses, exhibition halls, and museums. The light-transmitting roof of other special landmark buildings; the upper ground of underground shopping malls, supermarkets, railway stations, subways, etc. The shape of the skylight concentrator is spherical or pyramidal, and the lower part can be made into various shapes such as rectangular, square, circular, triangular, and trapezoidal, and the height is generally not higher than 0.5 meters.

In the light guide system, the intensity of light collected by the light collector plays a decisive role in the system effect. The skylight concentrator needs to be installed on the top floor, and there is no shading around it, so the lighting effect is better. Installed on the top of the underground shopping mall, people moving close will block the light; when installed near the place where there are plants, when the plant grows higher than the light collector, it will block the light; on cloudy days, because the light is relatively weak, due to the light collector The lighting area is small and the light guiding effect is poor.

The light pipe lighting system described above includes the same number of rubber rings as the condenser lenses, and the condenser lenses are embedded in the light collecting holes through the rubber rings.

In the light pipe lighting system described above, the inner wall of the light collecting tube is pasted with a reflective film.

In the light pipe lighting system described above, the outer wall of the light collecting tube is a reflective surface.

In the light pipe lighting system described above, the ratio of the height to the inner diameter of the light collecting tube is greater than 5.

In the light pipe lighting system described above, the top of the light collecting tube is inclined to the north, and the included angle between the axis of the light collecting tube and the axis of the light pipe is 5° to 10°.

In the above-mentioned light pipe lighting system, the light collector includes a cylindrical, transparent light collecting cover, and the light collecting cover is buckled on the outside of the light collecting tube.

The light pipe lighting system described above includes a rainproof device, the upper end of the light pipe is fixed in the rainproof device, and the lower end of the light collecting cover is located on the rainproof device.

In the light guide lighting system described above, the light collecting cover is a tempered glass light collecting cover or a plastic light collecting cover.

The light collector of the light pipe lighting system of the utility model can be installed on the ground, is less affected by the surrounding environment, has a decorative effect outdoors, and can enhance the indoor lighting effect.

[detailed description]

The structure of the light guide tube daylighting system of the embodiment of the utility model is shown in Figures 1 to 4, including a light collector, a light guide tube 9, a diffuser 8 and a rainproof device 7.

The light collector is a cylindrical light collector, including a light collecting tube 1 and a cylindrical, transparent plastic light collecting cover 2 or tempered glass light collecting cover 2. The light collecting cover 2 plays a protective and waterproof role, and its airtightness and light transmission The resistance can reach 93%, and it has certain impact resistance.

The ratio of the height to the inner diameter of the light collecting cylinder 1 is greater than 5.

The upper end of the light guide tube 9 is fixed in the rainproof device 7, the lower end of the light collecting tube 1 is connected with the upper end of the light guide tube 9, the light collecting cover 2 is buckled outside the light collecting tube 1, and the lower end of the light collecting cover 2 is located on the On the rainproof device 7.

There are many light-collecting holes 101 on the side wall of the light-collecting cylinder 1, and a light-collecting lens 4 is inlaid with a rubber ring 3 on each light-collecting hole.

The light-guiding and reflective material of the light-collecting tube 1 is based on an aluminum thin plate, which is a double-surface high-efficiency reflective film structure. Its single reflection efficiency is as high as 99.8%, and it has a high-efficiency reflection effect on the light collected by the lens.

The sunlight passes through the condenser lens 4 and hits the high-efficiency reflective film on the inner wall of the light-collecting tube 1, and is transmitted to the indoor light guide tube 9 through multiple high-efficiency reflections, and finally diffuses the light into every corner of the room through the diffuser 8.

During installation, the top of the light collecting tube 1 is inclined to the north, and the angle α between the axis of the light collecting tube 1 and the axis of the light guide tube 9 is 5° to 10°, and the light collecting tube 1 can receive the strongest light from the sun at this angle .
