Hybrid Lighting Promises Cool, Efficient Light and More…

In a solar lighting and power system,
the roof-mounted concentrators collect sunlight and distribute it through
the optical fibers (enlargement) to hybrid lighting fixtures in the
building’s interior


A
collector focuses the visible portion of sunlight
into an array of optical fibers while simultaneously converting
otherwise wasted infrared energy into electricity


Hybrid light fixtures
combine light from natural and electric sources to illuminate
building interiors. Energy is saved because electric lights are
dimmed in proportion to the amount of sunlight available



Flexible
optical fibers efficiently pipe sunlight into
buildings and route the natural light to multiple “hybrid”
light fixtures
