Hybrid lighting goes to school

In this project we have developed a new type of energy-saving lighting systems that use a combination of daylight and LED lighting.

The new lighting systems in the project have been implemented and tested at Hotherskolen in Hårlev and we have in the project assessed both quantitative and qualitative aspects of control performance, energy consumption, consumption time and light quality.

Hybrid lighting systems that use a combination of daylight and LED lighting have electricity saving potential that is greater than the most efficient conventional light sources, currently used for indoor lighting. Despite the large CO2 savings potential, there are a number of issues that need to be solved before the technology can be developed into a competitive commercial product.

The project on Hotherskolen in Stevns municipality implemented the following three hybrid lighting systems:

• Hybrid sun tunnels with LEDs in a vestibule of the school
• LED with solar cells in a classroom
• Fiber Lighting that couples sunlight through thin optical fibers into the building

Project partners in the project are: DTU Fotonik , RUC, Stevns municipality, Kolding School of Design and Ibsen El.
