Solparasit
Solparasit - Sun Parasite - a lighting system for day light
and saved day light.
During the day the lamp transmits day light through fiber optics with the technique that Parans uses. Meantime solar cells act as light shades and collectors so that in the
evening LED:s can be turned on.
Each of the shades/solar cells have one LED and one battery, which means that they can be carried away to be used elsewhere. |
