Since 2003 PARANS has brought natural light to the indoor environment with the help of its green Swedish innovation – the PARANS system. With the new fourth product generation – the SP4 – you can bring natural light to every room, on every floor, in every building. PARANS’ solutions create unique indoor environments where the natural variation of outdoor sunlight is present.

Parans Solar Lighting offers sunlight for indoor environments through innovative technology and design. The system captures and leads the rays of the sun through the property – deep into buildings and far away from windows – and spreads the light in a way giving you a memorable experience.

The Parans system concentrates the sunlight, in a set of optical lenses mounted on a lens profile, into optical glass fibers. One lens per glass fiber. Four glass fibers are bundled into one optical cable that transfer the sunlight through the building to the specific room.

Collectors On The Roof 

Through innovative technology and design, the intelligent collectors follow the sun during the day, just like a sun flower. The collectors are modular, expandable and can meet your need for natural light in the best possible way.

Sunlight Is Lead 100 Floors

Fibre optic cables leads the sunlight 500 meters in and through the property while retaining both a high level of light quality and light intensity.

Experience The Sunlight Far Away From Windows

All people in every room, even deep into the building, can experience healthy natural light. The light can be spread in a variety of ways, creating the experience you demand.

The Effect Of The Parans Light

The animation of the principle sketch shows how the sun moves over the city, from sunrise to sunset.

The rays of the sun reach the collectors of the Parans systems on the roof. The University Building (left building) gets sunlight first. The receivers follow the sun during the day to catch all sun hours of the day. Through fibre optic cables sunlight is lead in and through the building which is lit up by Parans light: healthy sunlight via the Parans system. The rooms deep into buildings and far away from windows may flood in sunlight.

Then, the Parans light lit up the Hospital (centre building) and underground area with the metro. And finally the sunlight reaches the Office Building (right building).
