Selective radiation utilization apparatuses for high-efficiency photobioreactor illumination and methods thereof

摘要

A selective radiation utilization apparatus includes an optical filtering device and a modulation device. The optical filtering device transmits one or more selected spectral bands of incoming solar radiation and reflects one or more remaining bands of the incoming solar radiation. The modulation device spatially modulates one of the one or more selected spectral bands or the one or more remaining bands and directs the spatially modulated one of the one or more selected spectral bands or the one or more remaining bands towards a target of illumination.

1. A selective radiation utilization apparatus, the apparatus comprising:
an optical filtering device that transmits one or more selected spectral bands of incoming solar radiation and reflects one or more other non-selected bands of the incoming solar radiation in a different direction from the one or more selected spectral bands; and a modulation device that spatially modulates one of the one or more selected spectral bands and directs the spatially modulated one of the one or more selected spectral bands towards a target of illumination; a photovoltaic device positioned to convert the one or more other non-selected bands without the one or more selected spectral bands into electrical energy; and an electrical light delivery device coupled to the photovoltaic device that converts the electrical energy into modulated non-solar radiation in substantially the same one or more bands as the spatially modulated one of the one or more selected spectral bands.
