Abstract
A light element with a translucent surface includes an energy converter, wherein the translucent surface is so formed as to direct only that portion of the radiation onto the energy converter that impinges on the translucent surface. The energy converter may be a solar cell, a fluid line or a light guide. The light element is particularly suited for illuminating interior spaces with diffuse light.
Claims13
A greenhouse, comprising:
- a plurality of frame elements forming a frame of the greenhouse,
- a plurality of pillows having at least one upper translucent surface facing a radiation source, each pillow supported in a respective frame element,
- a fluid element having a fluid circulating therethrough and a lens system arranged inside each pillow and formed so as to direct and concentrate only the direct incident radiation that strikes the upper translucent surface onto the fluid element, and
- a thermodynamic machine extracting thermal energy from the fluid for producing at least electrical power.
1 more element
A modular greenhouse comprising:
- a plurality of modular optical elements, each optical element including first and second highly transparent cover sheets supported by a mechanically stable frame thereby forming a pillow, with a plurality of pillows forming an envelope for the greenhouse,
- an optical lens system arranged inside each pillow which directs and concentrates direct incident radiation that strikes the translucent cover sheets of each pillow, and
- a light collection and converting system arranged integrated in each said modular optical element for collecting light and converting light into energy.
