Introduction to Fiber-Optic Lighting
by Craig DiLouie and Randy Smith

Fiber-optic lighting, also called remote-source lighting, is a lighting system that uses plastic or glass fiber to distribute light emitted by a lamp housed in a special optical device called an illuminator. Fiber-optic systems may be side-emitting, meaning the fiber itself is lighted, with an appearance similar to neon. Or they may be end-emitting, meaning the light is distributed from the end of the fiber, possibly through a fixture attachment, with a resulting appearance that is nearly indistinguishable from a conventional fixture. To visualize how a fiber-optic system works, consider a garden hose, with the water pump as the illuminator and the hose as the fiber. The hose may be pierced so that it sprinkles water itself or it may pour water out of its end; the end can also be fitted with attachments to control water flow.

Fiber-optic lighting has two major sources of appeal to lighting specifiers-its capability to produce dramatic effects and the fact that the light source is located remotely from where the light is emitted. We can create starry ceilings, articulate architectural details in various colors, create dynamic signage and design colorful and kinetic environments. And because the electrical component of the system, the illuminator, is placed remote from where the light is distributed from the fiber or an attached fixture, we can: ·

Safely light applications where electricity poses a hazard, such as underwater areas · Light precious objects, merchandise displays and other heat- and UV-insensitive areas with minimal heat and, using an appropriate filter, virtually no UV output · Attach multiple fibers to a single illuminator to provide multiple light sources with a single lamp, saving energy and lamp purchasing costs and providing design flexibility · Place fixtures in more confined spaces or hard-to-reach spaces, reducing maintenance requirements

In following articles, we will review basic fiber-optic lighting terminology, types and application considerations.
