Sunlight collection at maximum efficiency with a
system-lens focusing and optical fiber transmission
The Himawari system consists of a lens focusing unit and optical fiber devices.
Its outdoor collector can collect sunlight always at maximum efficiency and transmit it through optical fibers to anywhere you want. Unlike conventional
solar lighting systems which uses skylights and mirrors, stable day lighting
is possible all day long without suffering constraints imposed by
room location, window orientation, and solar altitude.
In order to accurately track the sun as it continuously changes its position from sunrise to suset, Himawari is equipped with an automatic tracking system. A solar sensor and clock mechanism control the movement of the light focusing lens so that it is always accurately aimed at the
sun. Even when clouds block out the sun, the system can respond speedily to changes in the weather
Ultraviolet-free, so it's light gentle on the eyes and the skin
High-quality sunlight is what the Himawari System
provides. The tone of the light is natural and gentle
on the eyes, qualities that can not be reproduced
by any artificial illumination.
By using acrylic dome covering the lense and chromatic aberration through single lens focusing, the sun's UV
can be eliminated. Therefore, the light consists predominantly of visible rays, a kind of light that is
best suited for promoting photosynthesis in plants.
Since the Himawari system screens out ultraviolet rays,
it protects furniture and carpets from colar fading.
High-Purity Optical Fiber Enabling Flexible
Transmission Of Sunlight
Collected sunlight passes through optical fibers which transmit visible ray-dominated sunlight. Optical fibers
are so thin and flexible that they can freely transmit light
to rooms in any building, wheather old or new.
Energy Saving & Maintenance-Free
By using an energy saving type system that is powered by solar cells, you can reduce your electricty cost
Once the Himawari System is installed, it operates automatically without any need for manual operation.
Since the precision collector is covered with acrylic dome, daylighting is stable over a long duration, and
free from the effects of rain and dust.
