ARRANGEMENT FOR LIGHT ENERGY CONVERSION

摘要

There is provided an arrangement for light energy conversion which enables integration of one or more energy converting elements combined with one or more dichroic filters in a solar tube. A first set of dichroic filters may be mechanically aligned such that they direct infrared light towards the energy converting elements whilst the visible daylight is directed into an area to be illuminated. Alternatively all light may be directed towards the energy converting element or transmitted through the solar tube. The one or more energy converting elements may store the light into an energy storing element that in turn may be drained by artificial light under constant voltage. In this manner daylight is directly transmitted into the area to be illuminated when there is a demand.
