Energy-efficient schemes for integrative lighting

Integrative lighting aims at circadian entrainment by spectral and luminous intensity control of light.

Integrative lighting is today designed in a traditional lighting design perspective, namely with over-focus on the horizontal distribution of light, while circadian requirements call for the right light at the right time on a vertical plane. Current integrative lighting systems are also designed irrespective to actual daylight provision.

These together result in actual integrative lighting installation using as much as three times more energy than “traditional” LED installations. This project aims at rethinking the way in which (day)lighting schemes are conceived.

The goal is to reach visual and circadian requirements in an energy efficient way and with a high degree of satisfaction for the users.

The project also promotes internationalisation of research by supporting the Swedish participation in a newly approved IEA SHC/EBC Task.
