Fiber lighting refers to the transmission through the optical fiber conductor, which can conduct the light source to any area. It is the rise of high-tech lighting technology in recent years.
Optical fiber is the abbreviation of optical fiber, in the application of optical fiber into the mature stage, in the field of high-speed transmission of communication, is widely used. And the early application of optical fiber is the most popular, is the jewelry made by optical fiber catheter.
Brief introduction
The conductor of the optical fiber itself is mainly made of glass material (SiO2), its transmission is the use of light through the high refractive index of the medium, into the low refractive index medium above the critical Angle will produce total reflection principle, so that the light in this medium can maintain the characteristics of the light waveform to transmit. The core part of the high refractive index is the main channel of light transmission. The low refractive index shell covers the whole core. Because the refractive index of the core is much higher than the shell, it produces full reflection, and the light can be transmitted in the core. The purpose of the protective layer is mainly to protect the shell and the core is not easy to damage, but also to increase the strength of the optical fiber.
Luminescence mode
The application of optical fiber in lighting is divided into two ways, one is the endpoint light, the other is the body light. The part of light is mainly composed of two components: optical projection host and optical fiber. The projection host contains a light source, a reflective hood, and a color filter. The main purpose of the reflective cover is to increase the intensity of the light, while the color filter can evolve the color and transform the different effects. Body light is the optical fiber itself is a light body, will form a flexible light strip.
Most of the optical fibers used in the lighting field are plastic optical fibers. In different optical fiber materials, the production cost of plastic optical fiber is the cheapest, compared with quartz optical fiber, often only one tenth of the production cost. Because of the characteristics of the plastic material itself, whether in the post-processing or the variability of the product itself, it is the best choice of all optical fiber materials. Therefore, for the optical fiber used in lighting, the plastic optical fiber is selected as the conduction medium.
main features
1. A single light source can simultaneously have multiple luminous points of the same luminous characteristics, which is conducive to use in a configuration of a wide area.
2. The light source is easy to replace, but also easy to repair. As mentioned earlier, the fiber lighting uses two components: the projection host and the fiber. The service life of the optical fiber is up to 20 years, and the projection host can be separated, so it is easy to replace and repair.
3. The projection host and the real light point are transmitted through the optical fiber, so the projection host can be placed in a safe position, with the function of preventing damage.
4. The light at the luminous point is transmitted through the optical fiber, and the wavelength of the light source is filtered, The emitted light is free of ultraviolet light and infrared light, which can reduce the damage to certain items.
5. Small light point, light weight, easy to replace and install, it can be made into very small
6.it is not affected by electromagnetic interference, can be applied in the nuclear magnetic resonance room, radar control room….. and other special places with electromagnetic shielding requirements, and this is other lighting equipment can not achieve the characteristics.
7. its light and electricity are separated. The most important problem with general lighting equipment is that it needs power supply and transmission. Also because of the conversion of power energy, the relative light body will also produce heat. However, in the attributes of many space, for safety considerations, most hope that light and electricity can be separated, such as oil, chemical, natural gas, pool, swimming pool and other space, all hope to avoid the electric part, so optical fiber lighting is very suitable for application in these fields. At the same time, its heat source can be separated, so it can reduce the burden of the air-conditioning system.
8.the light can be spread flexibly. General lighting equipment has the linear characteristics of light, so to change the direction of light, you have to make use of different shielding design. And optical fiber lighting is the use of optical fiber for light conduction, so it has the characteristics of easily changing the direction of irradiation, but also conducive to the special design needs of designers.
9. it can automatically change the light color. Through the design of the color filter, the projection host can easily change the light source of different colors, so that the color of the light can be diversified, which is also one of the features of optical fiber lighting.
10. the plastic optical fiber material is soft and easy to fold but not easily broken, so it can be easily processed into a variety of different patterns.
Because optical fiber has the above characteristics, we think it is the most variable in design, and therefore the best way to assist the designer to practice his design concept.
Application field
The application environment of optical fiber is becoming more and more popular, and we simply classify it as 5 areas.
1. interior illumination
Optical fiber applications in indoor lighting is the most popular, common applications have the ceiling star effect, like the well-known Swarovski uses the combination of crystal and optical fiber, developed a set of unique star lighting products. In addition to the starry sky lighting of the ceiling, there are also designers who use the body light of optical fiber to do the design of indoor space, using the effect of optical fiber flexible lighting, you can easily create a curtain of light, or other special scenes.
2.Waterscape lighting
Because of the hydrophilic characteristics of optical fiber, coupled with its photoelectric separation, so the use of the waterscape lighting, can easily create the designer wants, and on the other hand, it does not have the electric shock problem, can achieve safety considerations. In addition, the application of the structure of the optical fiber itself, can also be matched with the pool, so that the optical fiber body has also become a part of the waterscape, which is other lighting design is not easy to achieve the effect.
3.Pool lighting
Swimming pool lighting or now popular SPA lighting, the application of optical fiber is the best choice. Because this is the place of human activities, the safety consideration is much higher than the above pool or other indoor places, so the optical fiber itself, as well as the color of the diverse color effect, and can meet the needs of this kind of place.
4.architectural lighting
In the building, most of the optical fiber lighting is used to highlight the outline of the building. Also because of the characteristics of photoelectric separation, in the maintenance cost of the overall lighting, can be effectively reduced. Because the life of the optical fiber body is as long as 20 years, the optical projection machine can be designed in the internal distribution box, and the maintenance personnel can easily replace the light source. And the traditional lighting equipment, if the design of the location is more special, often have to use a lot of machines and facilities to maintain, the cost of consumption is much higher than the optical fiber lighting.
5.Architectural and cultural relics lighting
Generally speaking, ancient cultural relics or ancient buildings are easy to accelerate the aging because of ultraviolet light and heat. Because the optical fiber lighting does not have ultraviolet light and heat problems, so it is very suitable for the lighting of this kind of places. In addition, the most common application now is in the commercial lighting application of diamond jewelry or crystal jewelry. In the design of this kind of commercial lighting, most of the key lighting methods are adopted to highlight the characteristics of the commodity itself through the key lighting. The use of optical fiber lighting is not only no heat problem, but also can meet the needs of key lighting, so this kind of commercial space is also a widely used part of optical fiber lighting.
