Application of Plastic Optical Component with Microstructures

Nowadays, many buildings with oversized area cause rooms
located at the center of floors have no windows toward the
outside of the buildings. The only illuminants are electric
lamps, whose spectrum is artificially. People usually feel
uncomfortable when they stay in the rooms lack natural spectrum.
This may lead the body and mind development to be unbalanced.
Therefore, the ambient light should come from nature, the
The most direct and economical way to obtain the sunlight
in rooms is leading the sunlight to the rooms from outside.
Window, in the architecture, refers to the channel which
enters light and air into a room. In order to build a more
natural ambient light, the sunlight from outside of the
building casts into the room through Bright Windows system.
Bright Window system is constructed by three major parts,
Solar Panel, Optical Cable and Virtual Window. Solar Panels
are set on the roof or outer wall of the house. They gather
large area of sunlight and focus the light to thin light
beams. These beams are lead to the interior through Optical
Cable, which connect Solar Panels and Virtual Windows. The
light beams are scattered to be Surface illuminants by the
tiny optical structures on the windows. If we install curtains
or louvers in front of the virtual Windows, the light and
shade will present more like the real ones.
