Classification: CPC A  H  Y | IPC A  H

Claim 0:
1. A light source, comprising:
a light source module configured to emit light toward a plant, the light source module including:
a controller operable to turn on the light module during a light period, and
a plurality of light emitters, the plurality of light emitters including:
a first light emitter having a first active layer emitting light having a first peak wavelength within a first color wavelength band range,
a second light emitter having a second active layer emitting light having a second peak wavelength within a second wavelength band range, and
a third light emitter having a third active layer emitting light having a third peak wavelength different from the second peak wavelength,

wherein the light source module produces a plurality of types of light having different spectral patterns each other,
wherein the controller operates at least one of the plurality of light emitters to provide a first type of light having a first spectral pattern including a relatively high intensity of the first peak wavelength,
wherein the controller operates at least one of the plurality of light emitters to provide a second type of light having a second spectral pattern including a lower intensity of the first peak wavelength, and
wherein the controller selects one of the first and second spectral patterns for at least one growth mode of the plant during the light period.
