Indoor Lighting and Health Care

Electrical lighting is often employed in environments which natural sunlight cannot reach. This has meant that indoor electric lighting has been used in these spaces to solve a lighting requirement. The problem with this, though, is that all of the health benefits of natural daylight are lost.

However, there is a better way to light spaces that are away from natural daylight; opting for a lighting system that captures the sun’s rays, and transports them into these spaces, really makes good sense. When this is done, all of the health benefits associated with sunlight hitting human skin is transported into these spaces as well.

When we think of health care buildings, it would seem to make sense to opt for a lighting system that will capitalise on the benefits of natural sunlight.

Parans Health Care Lighting Solution

The Presbyterian / St. Luke’s Medical Center’s Neonatal Unit was searching for a lighting solution that would bring the full spectrum of healthy natural daylight into these sensitive health care environments. From the outset, the requirements were clear that the basic wall, ceiling and floor structures should not be changed.

With extensive construction work not possible, there would need to be an alternative solution. This indoor lighting solution would need to be introduced in harmony with the existing structure, while still bringing in natural sunlight.

The Parans lighting system was the only viable solution. Parans roof-mounted receivers were put in position and these continually tracked the sun, throughout the whole day. The healthy natural sunlight that was harvested by the receivers was then transmitted to Parans luminaires through fibre optic cables.

The Parans health care lighting solution uses no electricity, and has no costly construction associated with it. In addition to this, there is no heat gain, which is beneficial in the case of a health care environment.

Parans Work Drive

Paran’s philosophy is straightforward: “Use sunlight first and artificial when you must”. With this, the Swedish green tech company strives to build a sustainable world for human beings by creating an excellent indoor environment. The latest Paranslight solution gives sunlight to a room whether it is on the 2nd, 10th, or 30th floor.

Why Is Parans’ Lighting System Unique?

Unlike most lighting companies, Parans uses thin and flexible fibre-optic cables. These cables are installed over ceilings and through walls. Rather than relying on the traditional ways of restructuring buildings to allow the entrance of natural light, the cables are drawn inside healthcare buildings. This is made possible by well-trained and experienced engineers.


Healthcare facilities can now experience high productivity and many more well-being benefits that come as a result of the availability of sufficient natural light; this is thanks to Parans. The company has made into reality the dream of turning indoor lighting into solar lighting even in a built environment.
