The fiber optic lighting in recent years a new kind of lighting the way. The fiber itself has some unique physical properties, fiber optic lighting is used in interior lighting, local effects lighting, advertising license, the building outdo or public areas of the boot lighting, indoor and outdoor underwater lighting and building contours and elevation lighting and good lighting effects. The fiber optic lighting system is composed by the light source, mirrors, filters, and fiber. When the light through the mirror, a bouquet of approximately parallel light. The role of the filter, the beam into a colored light. When the beam into the fiber, colored light with the fiber path to the intended place. Due to the loss of light on the way, the light source is generally very strong. The commonly used light source for the about 150 ~ 250W. And in order to obtain approximate parallel beam emission point should be as small as possible, similar to point source. The mirror is an important factor in the availability of approximately parallel beam. So generally use the the the non-spherical surface reflective mirror. The filter is to change the beam color parts. Needed, with the exchange of different color filters, the color li ght. The fiber is the main fiber optic lighting system, the role of fiber optical transmission or transmitter to a predetermined place. The fiber is divided into the side light-emitting and light emitting two. The former is the beam reached the endpoint through the taillights lighting, while the latter itself is a luminous body, forming a flexible light beam. Terms of the fiber material in the visible range of light energy should be minimum loss in order to ensure the quality of lighting. But in fact can not be without loss of optical fiber transmission distance of about 30m or so for the best.

Characteristics of fiber optic lighting:

A. A single light source can have multiple light-emitting characteristics of the same luminous point.

Two. Light and easy to replace, and also easy to maintain.

3. The emitter can be placed in difficult to reach the location of non-professionals, so it has anti-destructive.

4. Ultraviolet, infrared light can reduce the damage of certain items such as artifacts, textiles.

5 Light-emitting point the miniaturization of, led underground light weight, replacement of Yi, installation, can be made into the the a very small size, placed in the the glassware or other within the the small objects of light-emitting the formation of the special decorative lighting effects.

6. No are electromagnetic interference, can be be applied in the the within the the nuclear magnetic resonance room, radar control room, and and so on on there are the electromagnetic to shielded the requirements of special places.

7. No spark, no risk of electric shock, can be used in chemical, petroleum, natural gas platform, fountains, swimming pools, fire, explosive, or a special place in the wet and water.

8. Can be automatically transform the the light color.

9. Can be reused, savi ng investment.

10. Soft and easy to fold non-friable, and easily processed into a variety of patterns. System heat lower than the general lighting system, can reduce the power consumption of air conditioning systems.

Second, LED lighting

The LED (Light Emitting Diode) yes the the the one kinds be able to will convert electrical energy into of semiconductor of the visible light, It has changed the the incandescent lamp tungsten wire to light-emitting the light-emitting the principle of as the with the three the base color dye of energy-saving lamps, while the use the electric field light-emitting. It has the following characteristics:

A. Voltage: LED low-voltage power supply voltage between 6-24V, depending on the product, so it is safer than the use of high voltage power supply.

Two. Performance: 80% reduction in energy consumption than the same luminous efficiency of incandescent.

3. Applicability: small piec es of each unit LED is 3-5mm square, so the device can be fabricated into various shapes and is suitable for the environment variable.

4. Stability: 10 million hours, the light decay of the initial 50%.

5 Response time: response time of its incandescent millisecond response time of LED lights for a nanosecond.

6. On the environment pollution: Nil are the harmful metallic mercury.

7. Color: change the current color, light-emitting diodes by chemical modification methods to adjust the material band structure and band gap, orange red Huanglv Lan multicolor light-emitting.

8. Price: LED s are expensive, the price of a few LED s on the price of an incandescent, but usually each signal by 300 to 500 diodes.

Third, fiber optic lighting applications place

A. Video conferencing desktop lighting

Two. Placed on top of high, difficult to maintain the effect of lighting or can not load-bearing place
3. Building outdoor public areas of leading lighting

4, an outdoor fountain underwater lighting

5 Building contour lighting and facade led lights for homes

6. Buildings, heritage local lighting

7. Light box, billboard

Line light-emitting the the Yi fold of the fiber-optic soft non-friable and, susceptible to processed into different shapes, which, no electric shock dangerous, without the need the high-voltage transformer, can be automatically transform light color, and construction and installation convenient, able to repeat to use. Often used to set the building on the billboard. Compared with the traditional neon, fiber optic lighting with the use of performance advantages.
