concept

Fiber optic lighting system is composed of light source, mirror, color filter and optical fiber. LED fiber optic lighting can create many gorgeous colorful effects, such as: crystal star constellation, twelve constellations, meteor shower, sky waterfall, waterfalls, fiber curtain wall, vertical curtain, three-dimensional mirror painting and so on the effect, colorful, It is a perfect combination of art and life. It is widely used in high-end entertainment such as star hotel, bar, nightclub, KTV, disco, sauna, bathing center and so on.

2 working principle

Fiber optic lighting system is composed of light source, mirror, color filter and optical fiber.

When the light source through the mirror, the formation of a bundle of similar parallel light. Due to the role of the color filter, turn the beam into color light. When the light beam into the fiber, the color of light with the fiber path to a predetermined place.

As the light in the way of loss, so the light is generally very strong. Commonly used light source is about 150 ~ 250W. And in order to obtain an approximately parallel beam, the light emitting point should be as small as possible, similar to the point light source.

Whether the mirror is an important factor in obtaining an approximately parallel beam. So the general use of non-spherical mirror.

The color filter is a part that changes the color of the beam. According to the need, with the exchange of different colors of the filter to obtain the corresponding color light source.

Fiber is the main body of fiber optic lighting systems, the role of optical fiber is transmitted or transmitted to a predetermined place. Optical fiber is divided into two kinds of luminous and luminous. The former is the beam to the endpoint, through the taillight lighting, while the latter itself is the luminous body, forming a flexible light beam.

For optical fiber materials, must be in the visible range, the light energy should be minimized to ensure that the lighting quality. But in fact can not be no loss, so the optical fiber transmission distance of about 30m or so for the best.

Fiber has a single, multi-strand and reticular three. For single-strand fiber, its diameter is Ф6 ~ Ф20mm. At the same time can be divided into two kinds of body light and end light. And for multi-strand fiber, are the end of light. Multi-strand fiber diameter is generally Ф0. 5 ~ Ф3mm, and the number of shares is common for a few root to hundreds of roots.

Mesh fiber is composed of fine diameter optical fiber composition can be composed of flexible optical band.

In theory, the light is linearly propagated, but in practical applications, people want to change the direction of light transmission.Through centuries of unremitting efforts of scientists, the use of lenses and mirrors and other optical components to infinitely change the direction of transmission And the emergence of fiber optic lighting, it is built in a limited number of changes in the direction of light transmission, to achieve the flexible transmission of light.As the arc after several times after the split into a straight line, fiber optic lighting is an infinite reflection, the light With the optical fiber path to achieve a flexible transmission.But the flexibility of fiber optic transmission, and did not change the light of the classical theory of linear transmission.

The fiber is made of polymer solution of liquid polymer, which has the characteristics of strong light guide, energy saving, durable, no heat, no pollution, flexible, variable color, wide environmental adaptability and safe use. Optical fiber light guide way is divided into soft and warm line of optical fiber and shiny light fiber, widely used in building decoration lighting, landscape lighting, cultural relics lighting, special occasions lighting, billboards, entertainment and other Decorative lighting works. Fiber type ordinary type solid line light light, PVC solid line light light, thermoplastic solid point light light, PVC solid point light fiber
