Abstract
A grow light includes a plurality of cool white LEDs, a plurality of warm white LEDs, and a driver electrically coupled to the cool white LEDs and the warm white LEDs. An intensity level and spectral composition of the radiant energy emitted by the grow light may be tuned or configured by varying a ratio of the quantity of cool white LEDs to the quantity of warm white LEDs, by varying a spatial arrangement among the cool white LEDs and the warm white LEDs, or by varying a level of current provided to some or all of the cool white LEDs and the warm white LEDs.

A horticulture grow light comprising:
- a first plurality of white light emitting diodes (LEDs) having a first color temperature;
- a second plurality of white LEDs having a second color temperature, the second color temperature being different from the first color temperature;
- a plurality of supplemental radiation emitters;
- and
- a driver configured to drive the first plurality of white LEDs, the second plurality of white LEDs, and the supplemental radiation emitters to provide an overall spectral composition,
- wherein the overall spectral composition of radiant energy collectively emitted at a same time by the first plurality of white LEDs, the second plurality of white LEDs, and the supplemental radiation emitters has a peak wavelength in a range from 430 nm to 460 nm and a peak wavelength in a range from 560 nm to 780 nm, and
- wherein, when a highest one from among the 430 nm to 460 nm peak wavelength and the 560 nm to 780 nm peak wavelength has a relative spectral value of 1, an entire wavelength range between the highest one of the peak wavelengths and the other one of the peak wavelengths has a relative spectral value of at least 0.2.
A method of growing a plant by using a horticulture grow light, the horticulture grow light comprising:
- a first plurality of white light emitting diodes (LEDs) having a first color temperature;
- a second plurality of white LEDs having a second color temperature, the second color temperature being different from the first color temperature;
- a plurality of supplemental radiation emitters;
- and a driver configured to drive the first plurality of white LEDs, the second plurality of white LEDs, and the supplemental radiation emitters to provide an overall spectral composition, wherein the overall spectral composition of radiant energy collectively emitted at a same time by the first plurality of white LEDs, the second plurality of white LEDs, and the supplemental radiation emitters has a peak wavelength in a range from 430 nm to 460 nm and a peak wavelength in a range from 560 nm to 780 nm, and wherein, when a highest one from among the 430 nm to 460 nm peak wavelength and the 560 nm to 780 nm peak wavelength has a relative spectral value of 1, an entire wavelength range between the highest one of the peak wavelengths and the other one of the peak wavelengths has a relative spectral value of at least 0.2, the method comprising:
- irradiating the overall spectral composition of radiant energy from the horticulture grow light toward the plant.
