What Is a Fiber-Optic Illuminator?
Fiber-optic lighting refers to transmission through fiber-optic conductors, which can transmit light sources to any area. It is a high-tech lighting technology emerging in recent years.
Fiber optic lighting
- The conductor of the optical fiber itself is mainly made of glass material (SiO2). Its transmission is based on the principle that light passes through a high refractive index medium and enters a low refractive index medium at an angle higher than the critical angle. , So that light in this medium can maintain the characteristics of the light waveform for transmission. The core part of the high refractive index is the main channel for light transmission. The low refractive index shell covers the entire core. Since the refractive index of the core is much higher than that of the shell, total reflection will occur and light can be transmitted in the core. The purpose of the protective layer is mainly to protect the shell and the core from being easily damaged, and also to increase the strength of the optical fiber.
- The application of optical fiber in lighting can be divided into two types, one is end-emission light, and the other is volume light. The light emitting part of the endpoint is mainly composed of two components: a light projection host and an optical fiber. The projection unit includes a light source, a reflector, and a color filter. The main purpose of the reflector is to increase the intensity of the light, and the color filter can evolve the color and transform different effects. Bulk emission means that the optical fiber itself is a light emitter, which will form a flexible light bar.
- Most of the optical fibers used in the lighting field are plastic optical fibers. Among the different optical fiber materials, the production cost of plastic optical fiber is the cheapest. Compared with quartz optical fiber, it is often only one tenth of the production cost. And because of the characteristics of the plastic material itself, it is the best choice among all fiber materials, whether in post-processing or the variability of the product itself. Because of this, the optical fiber used for lighting uses plastic optical fiber as the conductive medium.
- 1. A single light source can have multiple light emitting points with the same light emitting characteristics at the same time, which is conducive to use in a wide area configuration.
- Second, the light source is easy to replace and easy to repair. As mentioned earlier, fiber optic lighting uses two components: the projection host and the fiber. The optical fiber has a service life of up to 20 years, and the projection host can be separated, so it is easy to replace and maintain.
- 3. The projection host and the real light emitting point are transmitted through the optical fiber, so the projection host can be placed in a safe place with the function of preventing damage.
- 4. The light from the luminous point is transmitted through the optical fiber. The wavelength emitted by the light source is filtered and contains only a certain spectrum. Therefore, the emitted light is free of ultraviolet and infrared light. This characteristic can reduce the damage to certain items. .
- Fifth, the light emitting point is miniaturized, light in weight, easy to replace and install. It can be made into a small size and placed in different containers or its design space, so it can create a distinctive decorative lighting effect.
- 6. It is not affected by electromagnetic interference, and can be used in special places such as nuclear magnetic resonance room, radar control room, etc. that require electromagnetic shielding, which is a characteristic that cannot be achieved by other lighting equipment.
- 7. Its light and electricity are separated. The most important problem of general lighting equipment is that it requires power for transmission. Because of the conversion of electric energy, the light-emitting body also generates heat. However, in many space properties, for safety considerations, most people want to separate light from electricity. For example, spaces such as petroleum, chemical, natural gas, pools, swimming pools, etc., want to avoid electricity, so fiber optic lighting is suitable Applications in these areas. At the same time, its heat source can be separated, so it can reduce the burden on the air conditioning system.
- Eight, light can be transmitted flexibly. General lighting equipment has the linear characteristics of light, so to change the direction of light, you must use different shielding designs. Fiber optic lighting uses optical fibers to conduct light, so it has the property of easily changing the direction of illumination, which is also conducive to the needs of designers' special designs.
- Nine, it can automatically change the light color. The design of the transparent filter allows the projection host to easily change the light sources of different colors, so that the color of the light can be diversified.
- 10. The material of plastic optical fiber is soft, easy to fold and not fragile, so it can be easily processed into various patterns.
- Because the fiber has the above characteristics, we believe that it has the highest design variability, and therefore it can best assist the designer in practicing his design concepts.
- The application environment of optical fiber is becoming more and more popular. We simply classify it into six areas.
Fiber optic lighting
- Optical fiber is most commonly used for indoor lighting. Common applications include the starry sky effect of the ceiling. Like the well-known Swarovski, the combination of crystal and fiber optics has been used to develop a unique set of starry sky lighting products. In addition to the starry sky lighting on the ceiling, there are also designers who use fiber-optic volume lighting to design interior spaces. Using the effect of fiber-optic flexible lighting, light curtains or other special scenes can be easily created.
Fiber optic lighting
- Due to the hydrophilic nature of the optical fiber, coupled with its photoelectric separation, it can easily create the desired effect when used in the lighting of water features. On the other hand, it does not have the problem of electric shock and can achieve safety. Considerations. In addition, the structure of the optical fiber itself can also be used with the pool to make the optical fiber body a part of the waterscape. This is an effect that is difficult to achieve in other lighting designs.
Fiber optic pool lighting
- The lighting of swimming pools or the lighting of popular SPA occasions, the application of optical fiber is the best choice. Because this is a place for human activities, the safety considerations are much higher than the pool above or other indoor places. Therefore, the optical fiber's optical separation characteristics and the various color rendering effects can meet the needs of this type of place.
Fiber-Optic Lighting
- In architecture, most of the light-emitting optical fiber lighting is used to achieve the effect of highlighting the outline of the building. Because of the characteristics of photoelectric separation, the maintenance cost of the overall lighting can be effectively reduced. Because the life of the fiber body is as long as 20 years, and the light projector can be designed in the internal distribution box, maintenance personnel can easily replace the light source. However, if the traditional lighting equipment is designed in a special position, many machines and facilities can be used for maintenance, and the cost consumption is much higher than that of fiber optic lighting.
Fiber Optic Lighting

- Fiber optic lighting
Fiber optic lighting flammable and explosive lighting
- In oil storage, mining areas, chemical plants and other dangerous places where fire is strictly prohibited, other lighting equipment has the danger of open flames. This part of fiber optic lighting can solve this kind of problem. In the medical or special experimental environment, the place with electromagnetic shielding problems is also part of the strength of fiber optic lighting.
- Sincerely, in the application part of fiber optic lighting, we have already performed several projects, whether in indoor lighting, pool lighting, swimming pool lighting or commercial lighting, we have rich experience. With the popularization and maturity of optical fiber products, more practical cases of optical fiber applications will be seen in the future.
