light pipe

Domestic light pipe
Credit: Wikipedia |
A device that gathers incoming sunlight sometimes using a solar tracking
system. The light is concentrated using lenses or mirrors and is then transmitted
to the interior of a building by special tubes. These may may be hollow
shafts or ducts with reflective internal finishes, or may use fiber optic
cable technology. A special luminaire
is required to provide distribution of the light within the building.
A light pipe system depends heavily on the availability of sunlight. For
critical taks a back-up artificial light source is required.
Light pipes are becoming more and more popular, especially in areas that
are mostly used during the day such as storage spaces and in domestic applications,
e.g., in hallways. They are relatively inexpensive and easily retrofitted
into an existing building. Related category
