Due to the idea of everlasting green architecture, it is of increasing importance to guild natural light into
indoors. The advantages are multifold - to have better color rendering index, excellent energy savings from
environments viewpoints and make humans more healthy, etc. Our search is to design an innovative structure,
to convert outdoor sun light impinges on larger surfaces, into near linear light beam sources, later convert this
light beam into near point sources which enters the indoor spaces then can be used as lighting sources indoors.
We are not involved with the opto-electrical transformation, to the guild light into to the building, to perform
the illumination, as well as the imaging function. Because non-imaging optics, well known for apply to the
solar concentrators, that can use non-imaging structures to fulfill our needs, which can also be used as energy
collectors in solar energy devices. Here, we have designed a pair of large and small parabolic reflector, which
can be used to collect daylight and change area from large to small. Then we make a light-guide system that is
been designed by us use of this parabolic reflector to guide the collection light, can pick up the performance
for large surface source change to near linear source and a larger collection area.
