Fiber Introduction
• An optical fiber ( optical fibre) is a flexible, transparent fiber made of high quality extruded glass or plastic, slightly thicker than a human hair. It can function as a waveguide, or “light pipe”, to transmit light between the two ends of the fiber.

How the signal travels in optical fiber
Signal goes ahead through reflection in the glass pipe. So it can travel very fast.The speed is very close to the light speed.

The normal use of optical fiber
Because it can Conduct electrical signals.It is used in many places, like the phone And the internet.

Optical fiber in Arch
• In1998, the Licht'98 was held in Germany, Bregenz. More than 700 people attended this meeting. The meeting is very concerned about the architect architectural lighting and the optical fiber lighting system was first mentioned at this meeting.

We all know that the sun hasa great influence on building.But it just a little sunlight go through the windows. So much Sunlight is absorbed by building.That means in the building a lotof places have no light and they need electric light. At the same time a lot of sunlight just make The building hot and also need electric energy to keep cool in Summer.

• The optical fiber lighting can solve this problem and it works like this way.

The example
This building is built by Qinghua University in China. It uses opticalFiber lighting system to explore howThe system work and how many benefitsIt can produce.

A small idea about the optical fiber lighting system
Many people like sunbathing, but we all know that the sunlight is not a singleLight. It has three parts UV visible and infrared. The UV is very harmful to
people’s skin.

Because they are different lights, when they reflect inside the optical fiber, theirs rotation angles are different. So at the end of fiber we can just let the visible light Pass by control the distance between the terminal and the fiber Fiber can use this in the acceptance process can be controlled by the distance just let visible light pass.

You can enjoy sunbathing safely oreven inside the room
