Fiber optic display lighting is made up of optical fiber. Optical fibers are the fibers of the thickness equal to the human hair, made from glass or plastics and generally used as a medium of wavelength transmission from its one end to another end.  An optical fiber can even transmit light over a curved path. Fiber optic lighting is different and flexible from traditional lighting system in many ways such as low maintenance, zero emissions, better control and illumination, easy fittings, and such other benefits.

Since the fiber optics do not require any electricity, ultraviolet rays or heat to function, these are considered safe for the commercial uses. Display lighting systems use the fiber optics often because the source of illumination is at the distance from the point of application. Hence these can be used with water, combustible substances, paintings and other decorative items and this distance also make them theft free and safe. And since it does not produce any heat on illumination, these can be also used in heat sensitive or temperature sensitive areas.  

The high band width of the optical fiber makes fiber optic display lighting even more popular for the commercial use, because the higher bandwidth means it can be used even in the longer distances as the transfer medium without leaking the light. Also the display lighting systems using the fiber optics are economic than other conventional lighting systems, as the single light source can be used with the multiple fixtures or applications.

Coming to the size, weight and dimensions then optical fibers are light weight, smaller diameter and are generally of the cost of the copper wires. Most commonly fiber optic display lighting is used for the decorative purposes but there are many other uses also. The illumination is focused and directed. These can often be noticed at trade fairs, front windows of the shops, restaurants, nightclubs and casinos, swimming pools, aquariums, gardens, Christmas trees and etc.
So when next time you think of display lighting, think of optical fibers. They are cost effective, safe, secure, low maintenance, durable and with zero emission. Your one time investment can actually benefit you for long.
