Installation method and matters needing attention of optical fiber lamp

Optical fiber lighting is a lighting system composed of reflector, light source, color filter and optical fiber. The characteristic of fiber-optic lighting is that it can emit many colorful pictures, which is exciting. Mainly used in some high-end places for leisure and entertainment, such as discos, star-rated hotels, nightclubs, bars, nightclubs, bath centers and so on. Sauna and other places. I believe everyone must be very interested in the knowledge of fiber-optic lamp installation. Don't worry, I'll give you some knowledge about the installation of fiber-optic lamps.

Brief introduction of optical fiber lamp

Optical fiber is the abbreviation of optical fiber, which is widely used in high-speed transmission communication field. In the early days, the most popular application of optical fiber was decorations made of optical fiber conduits. The structure of optical fiber can be simply divided into three parts, namely, core, cladding and sheath.

The conductor of optical fiber itself is mainly made of glass material (SiO2 _ 2), and its transmission is based on the principle that when light passes through a high refractive index medium and enters a low refractive index medium at an angle higher than the critical angle, it will produce total reflection, so that light can transmit in this medium while maintaining the characteristics of light waveform. The core part with high refractive index is the main channel of light transmission. The shell with low refractive index covers the whole core. Because the refractive index of the core is much higher than that of the shell, total reflection will occur, so light can be transmitted in the core. The purpose of the protective layer is mainly to protect the shell and core from damage, and also to increase the strength of the optical fiber.

Characteristics of fiber-optic lamps

1. A single light source can have multiple luminous points with the same luminous characteristics at the same time, which is beneficial to the configuration in a wider area.

Second, the light source is easy to replace and maintain. As mentioned earlier, optical fiber lighting uses two components: the projection host and the optical fiber. Among them, the service life of optical fiber is as long as 20 years, and the projection host can be separated, which is convenient for replacement and maintenance.

Thirdly, the projection host and the real luminous point are transmitted through optical fiber, so the projection host can be placed in a safe position and has the function of preventing damage.

4. The light emitted from the luminous point is conducted through the optical fiber, and the wavelength emitted by the light source is filtered and only contains a certain spectrum, so the emitted light has no ultraviolet light and infrared light, which can reduce the damage to some articles.

5. The luminous point is miniaturized, light in weight and easy to replace and install. It can be made into small sizes and placed in different containers or their design spaces, so it can create a unique decorative lighting effect.

6. It is free from electromagnetic interference and can be used in special places with electromagnetic shielding requirements, such as nuclear magnetic resonance room and radar control room. This is a feature that other lighting equipment cannot achieve.

Seven, its photoelectric separation. The most important problem of general lighting equipment is that it needs electricity to transmit. Because of the conversion of electric energy, the luminous body will generate heat relatively. However, in many spatial attributes, for the sake of safety, most of them want to separate light from electricity, such as petroleum, chemical industry, natural gas, pools, swimming pools and other spaces, all of which want to avoid electricity, so optical fiber lighting is very suitable for application in these fields. At the same time, its heat source can be separated, so the burden of air conditioning system can be reduced.

Eight, light can spread flexibly. General lighting equipment has the linear characteristics of light, so to change the direction of light, we have to use different shielding designs. Because optical fiber lighting uses optical fiber to conduct light, it is easy to change the irradiation direction, and it is also beneficial to the special design requirements of designers.

Nine, it can automatically change the color of light. Through the design of the color filter, the projector can easily change the light sources with different colors, which is one of the characteristics of optical fiber lighting.

X. Plastic optical fiber is soft, easy to fold and not fragile, so it can be easily processed into various patterns.

Optical fiber lamp application

In fact, optical fiber lighting has been used by people since 1930s. At that time, the main raw material was clustered glass, but the cost was high. It was not until the 1960s that the plastic optical fiber with polymethyl methacrylate as the core appeared, but it encountered the problem of large loss. It was not until the end of 1970s that optical fiber lighting was paid attention to and successfully industrialized and commercialized. In China, fiber-optic lighting was really used and popularized in the late 1980s, not only in decoration, but also in medical equipment and communication.

Optical fiber lamp installation

The first is the installation of the light emitter.

Lamps and lanterns are usually installed in places that are convenient for workers to operate and maintain and are not easy to be approached by people. Generally, the indoor lighting device can be directly installed on the bracket in the elevator room or in the distribution box with lock. If it is an outdoor light emitter, it can be placed on a special outdoor bracket, or it can be placed in a rain box with a lock outside and installed against the wall.

Followed by optical fiber installation.

Like some luminous cables, they can be laid directly through pvc plastic pipes. When installing, they should be as straight as possible to minimize bending. If it is bent, it is easy to cause bending loss. In general, the turning radius of optical fiber should be greater than or equal to 12 times the diameter. If the optical fiber emits light through wires, it is usually laid directly outside billboards and buildings. The tool is fixed by selecting a card or a cable tie, but when bending, the turning radius must be greater than or equal to 20 times the diameter. Pay attention to the waterproof measures outside the building.

Connection between point-emitting optical fiber and terminal accessories

Then the point-emitting optical fiber is usually connected to the light-emitting terminal through a special connection kit. In order to further determine the normal input of the optical system, the port accessories should be thoroughly cleaned when installing the optical fiber, and dust-proof measures should be taken during the whole connection process.

Finally, install the lighting terminal fittings.

The final installation of the luminous lamp is actually the same as the usual installation method of the lamp. Care should be taken when installing the luminous lamp to avoid collision. Attention should also be paid to dust prevention measures during installation.

Editor's summary: the material of optical fiber is very elastic, and it can achieve very good results when used in the unique design of works of art. Moreover, optical fiber has no harm to human body, no infrared rays and ultraviolet rays, no current and no heat itself. It has no problem when used in water, long service life and no electromagnetic interference. It can be said that it is a safe and useful lighting equipment.
