can we use optical fiber as a light source?

Question

sun light will be tranmitted through an optical fiber and it recive in side
the room .If it is possible we can reduse other light sources

Answer 1

Optical fiber is not a SOURCE of light, but it is an extremely good conductor of light.
Your idea is very practicable and is probably functioning already.

Answer 2

Yes, it is possible to use fibers to conduct sunlight inside. But the it isn't too straightforward to connect the sunlight into the fiber with good efficiency; solutions tend to be a bit costly when you want to get inside enough intensity to use as a light source. Windows are far more cheaper and efficient way; it's far wiser to cover your building with windows and thus illuminate the outer rooms well, than to cover the outside with fiber intakes and illuminate every room poorly. Only in some very special cases this kind of solutions could be economical.

But the fibers as a conductor of artificial light is widely used. It's easier to connect into the fiber, you can do nice tricks with decoration in mind, and you can illuminate hard-to-reach places and stuff.

Oh, and Mel: I really don't think this question was about light sources used to test optical fibers in data transfer applications. This was about illuminating a room. But hey, why to bother reading the question, or the single page you google?

Answer 3

I believe I heard of this being done in Hong Kong. Space is tight and many people live in apartments so they brought in sunlight through fiber optics that were connected to the outside. Very good idea really.

Answer 4

Yes. Surgeons use such sources now to achieve adequate illumination of the surgical field. However, the stuff is too expensive to be used much for general illumination.

Answer 5

"We already got one"
