Abstract
Embodiments described herein provide systems and methods for promoting plant growth that combine beam angle control with spectral control. In one embodiment, an optical device can be configured to emit multiple colors of light at particular wavelengths. The optical device may also be configured to generate an emission spectrum with multiple peaks. The spectrum can be selected based on stimulating biological processes of a plant.
Claims20
A system for plant growth comprising:
- a first LED device configured to emit light of a first color, wherein the first LED device is configured to emit light with a controlled beam half angle of less than or equal to 60 degrees;
- and
- a second LED device configured to emit light of a second color, wherein the second LED device is configured to emit light in a with a controlled beam half angle of less than or equal to 60 degrees;
- and
- wherein the system is configured to generate an emission spectrum having a first emission peak below 500 nm and a second emission peak above 600 nm.
