A shadowy space dramatically changes its atmosphere when it is suddenly
illuminated by natural sunlight. Anyone who has experienced this effect
will never forget the impression. In the past few years, architects
have applied complex daylight systems to counteract the lack of light
in the lower floors of large buildings. Yet a cheap and efficient
device that would bring sunlight to individual living and working areas
still does not exist.
The presented prototype is provided by a light-sensitive sensor to
trace the position of the sun. A simple mechanism transmits the
movement of the sensor and simultaneously adjusts the mirror-position
to just the right angle in order to keep the reflecting sunlight on the
selected spot. The construction and the set-up of the device’s support
is equal to that of individual satellite dishes used around the world.
There is undoubtedly a need for this device. In the city of Berlin
alone, at least 150,000 potential customers are waiting for the sun to
rise in their dark homes.
The principal idea of the helioflex concept was to create an automatic
device that could be inserted into the existing architecture and that
would permanently reflect direct sunlight to a chosen point. The device
must be inexpensive enough for those in dark homes to afford it.
The density of building generates a social gradient of sunlight in
urban areas: The top floors bathe in the light that is missing in the
bottom floors. The device bypasses this gradient and creates a
connection to the outside world by reflecting natural light to spaces
that have never seen the sun before.
