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 has
a 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 lot
of 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.

Himawar
12 Lens HIMAWARI XD-50S/12AS
Medium capacity model. Supplies sunlight
to 2 terminals.
36 Lens HIMAWARI XD-100S/36AS
Medium capacity model. Supplies sunlight
to 6 terminals.
90 Lenses HIMAWARI XF-110S/90AS
Large capacity model. Supplies sunlight
at 15 terminals
Saving calculation
The example
This building is built by Qinghua
University in China. It uses optical
Fiber lighting system to explore how
The system work and how many benefits
It can produce.
Inside the building
A small idea about the optical fiber
lighting system
Many people like sunbathing, but we all know that the sunlight is not a single
Light. 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 or
even inside the room
