Abstract:
1. 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 at least 50% of the light emitted by the first LED is in the controlled beam half angle of the first LED and at least 70% of the light emitted by the first LED is in the field angle of the first LED; and a second LED device configured to emit light of a second color, wherein the second LED device is configured to emit light with a controlled beam half angle of less than or equal to 60 degrees and at least 50% of the light emitted by the second LED is in the controlled beam half angle of the second LED and at least 70% of the light emitted by the second LED is in the field angle of the second LED; 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.
