After two years of research Italian designers, Diego Rossi and Raffaele
Tedesco, created the Zeno light for Luceplan, which works on optical conduits that collect exterior light and convey it in a
“direct and controlled way”.

Luceplan is an internationally known Italian
design firm. Over the past two years, the company has been carrying out
a special program of technological evolution and research on energy
applied to lighting, with particular attention to solar light. Energy
saving is one of the firm’s top priorities, meant to embrace the
environmental compatibility of their entire operation – from choice of
materials to the manufacturing process, from product durability to
product maintenance. This means designing beyond the birth of a
product. It includes anticipating the completion of its life cycle and
its disassembly, designing its recycling or reuse, innovating its
packaging and avoiding the use of pollutant paints and processes, all
of which will combine to reduce its impact on the environment.

is a noteworthy example amongst the eco-friendly lighting collection
produced by Luceplan. Its designers are Diego Rossi and Raffaele
Tedesco, two very young Italian architects interested in the
development of renewable energy applications. Zeno shapes a new
philosophy of light. Following the principles that stress solar light’s
therapeutic and healthful virtues, Luceplan has produced an artificial
‘natural’ light.

Zeno is designed
for direct use in places that cannot be reached by natural light, or in
areas dimly lit during the day. The product is a sophisticated system
that is able to integrate sunlight with artificial light from the most
advanced light sources (fluorescent, halogen, halide). Thanks to a
special system of optical conduits, natural light is picked up by
collectors placed outside the building and conveyed to the device,
which carries the solar radiation into the building in a direct and
controlled way.

The possibility of
having interfaced light sources of different efficiencies,
temperatures, colors and chromatic yields makes the system extremely
flexible from both a balanced light point of view and from that of
energy control. Zeno makes it possible for the first time to integrate
sunlight with artificial light sources. It is able to create different
atmospheres using just one apparatus, for example cooler and more
‘objective’ for workplaces, warmer and more secluded for domestic


In a not too distant future,
when sunlight collectors and optical conduits have more fully evolved,
it will be possible to distribute direct light from the sun and
subdivide the cost of the system amongst the tenants of an apartment
block, similarly to what happens today with television signals.
