Abstract A light for facilitating plant growth and a light emitting component. The fixture comprises at least two Light Emitting Diodes (LEDs) emitting light including far red light in a 5 wavelength range from 700nm-800nm and reducing green light below the light intensity in each of the bands adjacent to the green light, the emitted light including spectral emission peaks matching carotenoid and chlorophyll absorption peaks. The light for facilitating plant growth may instead comprise at least two luminescent UV light emitting diodes (LEDs), with external emission characteristics, the luminescent UV LEDs emitting light 10 including far red light in a wavelength range from 700nm-800nm and reducing green light below the light intensity in each of the bands adjacent to the green light, the emitted light including spectral emission peaks matching carotenoid and chlorophyll absorption peaks, phosphorescent emission intensities of the emitted light from the at least two LEDs being adjustable in any ratio to accommodate plant growth. The emission peaks of the LED 15 match well with a plant photosynthesis response spectrum and is therefore particularly suitable for high efficiency artificial lighting. |
