Brief discussion on optical fiber lighting technology

Abstract: optical fiber lighting is a new lighting method in recent years. Due to some unique physical characteristics of optical fiber itself, optical fiber lighting has been applied to indoor decorative lighting, local effect lighting, billboard lighting, guiding lighting of outdoor public areas of buildings, indoor and outdoor underwater lighting, building outline and facade lighting, and has achieved good lighting effects

key words: optical fiber lighting illuminator point light-emitting optical fiber side light-emitting optical fiber terminal accessories Untitled Document I. characteristics of optical fiber lighting optical fiber lighting has the following significant characteristics: 1 A single light source can have multiple light-emitting points with the same light-emitting characteristics; 2. The light source is easy to replace and repair; 3. The illuminator can be placed in a position that is difficult for non professionals to touch, so it is anti-destructive; 4. There is no ultraviolet and infrared light, which can reduce the damage to some items such as cultural relics and textiles; The company will definitely focus on new energy-saving electrode materials, high-efficiency energy storage materials and their preparation technology The light emitting point is miniaturized, light in weight, easy to replace and install, and can be made into a very small size. It can be placed in glassware or other small objects to emit light to form a special decorative lighting effect; 6. It has no electromagnetic interference and can be used in special places with electromagnetic shielding requirements such as nuclear magnetic resonance room and radar control room; 7. There is no electric spark, no danger of electric shock, and it can be used in special places with fire, explosive hazards or damp and water, such as chemical, oil, natural gas platforms, fountain pools, swimming pools, etc; 8. It can automatically change the light color; 9. It can be reused to save investment; 10. It is soft, easy to fold, not fragile, and easy to be processed into various patterns; The heating of the system is lower than that of the general lighting system, which can reduce the power consumption of the air conditioning system. 2、 Composition of optical fiber lighting system 1 The system configuration optical fiber lighting system can be divided into point light-emitting (i.e. end light-emitting) system and line light-emitting (i.e. side light-emitting) system, and their respective system configuration diagram is shown in Figure 1. 2. System composition (1) illuminator illuminator device includes light source, reflector, ultraviolet (UV) and infrared (IR) filters and rotating glass color disc (optional). According to the different internal light sources, it is generally divided into tungsten halogen lamp series and metal halide lamp series. The light source power of halogen tungsten lamp is generally 50W or 75W, and the input voltage is AC 12V (the device has its own power transformer), which is suitable for museums or exhibition halls and other places with special control requirements for temperature, humidity, ultraviolet and infrared; The light source power of metal halide lamp is generally 150W or 200W, and the input voltage is AC 220V. It is suitable for places with high brightness requirements such as building outline lighting and facade lighting. According to different degrees of protection, light emitting devices are generally divided into indoor and outdoor types. The rotating glass color disc can be configured into up to eight colors for automatic transformation. The device can be changed and controlled by the computer according to the setting program, and can also be synchronously controlled by the audio signal output by the audio system. The device has its own power plug, and the applicable power supply is AC 220V, 50Hz. (2) Light emitting conductor light emitting conductor is generally composed of plastic or glass fiber bundles or a single plastic fiber. Considering the light attenuation in the transmission process, its length is generally not more than 30m. It can be solved by the system in series. There are two common light-emitting conductors: 1 The spot light-emitting optical fiber is covered with a very thin plastic or glass fiber coating to prevent light from leaking out. It is covered with an opaque liner and a heat-resistant and UV resistant protective sleeve made of plastic, rubber or metal wire (used to protect and support the optical fiber), which can be divided into indoor and outdoor water-proof types, and both of them need to be equipped with light-emitting terminal accessories. 2. The line light-emitting optical fiber adopts a special structure, which can emit light all the way. It is covered with a transparent lining and a heat-resistant and UV resistant PVC transparent protective sleeve. Its outer diameter specifications are 8mm, 11mm and 15mm, which can be divided into indoor standard type and outdoor waterproof type. Both of them need to be equipped with non light emitting terminal accessories. (3) Terminal accessories, whether at the end of point light-emitting fiber or line light-emitting fiber, need to be equipped with terminal accessories. According to the different light-emitting characteristics of point light-emitting optical fiber and line light-emitting optical fiber, there are the following two types of terminal accessories: 1 Light emitting terminal accessories: equipped in various anti focusing professional subdivisions of point light-emitting optical fiber terminals, innovative and improved light-emitting or direct light-emitting accessories similar to lamps, including downlight type, lens type (condensing or dispersing light), ground specific type and underwater type terminals. 2. Non luminous terminal accessories: equipped with luminous optical fiber terminals, which are opaque sealed envelopes. 3、 Typical application due to the many characteristics of optical fiber lighting, its application is extensive. Now, the typical application is analyzed and explained according to different use places and use effects. 1. Many customers of the tabletop of the TV Club voluntarily require that the imported lighting adopt the end light-emitting system, which is equipped with a condensing lens type light-emitting terminal accessory, which is vertically illuminated from the top, forming a dot shaped spot on the tabletop, so that the participants can read and write through without affecting the slide projection interpretation (when the general lighting lamps are turned off or the brightness is reduced). 2. Effect lighting in places with high top, difficult to maintain or unable to bear load. The end lighting system is used for the star filled shape of the tall dome of the hotel lobby, equipped with astigmatic lens type lighting terminal accessories and rotating glass color disk, which can form a dynamic effect of stars glittering, which is far from being comparable to general lighting systems. 3. The guiding lighting in the outdoor public area of the building adopts the floor tube (line light-emitting) system or the buried place Chen guiding (end light-emitting) system for sign lighting, which reduces the workload of light source maintenance compared with the general lighting method, and has no leakage risk and high precision risk. 4. The underwater lighting of the outdoor fountain adopts the terminal light-emitting system, which is equipped with an underwater terminal for the underwater lighting of the outdoor fountain, and the light output and light color transformation can be synchronously controlled by the audio signal output by the sound system. Its lighting effect and safety are better than ordinary low-voltage underwater lighting system, and it is easy to maintain, without leakage danger. 5. Building outline lighting and facade lighting adopt the combination of line lighting system and end lighting system to illuminate the building wheel and facade. For example, the Christmas decorative lighting system on the facade of Bank of China Building in Hong Kong has fashionable patterns and rich color changes. The utility model has the advantages of convenient construction, short installation cycle, strong timeliness, and can be reused to save investment. 6. The indoor local lighting of the building adopts the end lighting system, which is equipped with condensing lens or astigmatic lens
