Lighting assembly

摘要

A lighting fixture for facilitating plant growth and a light emitting component. The fixture comprises a single light emission source LED device which provides at least two emission peaks in the wavelength range of 300-800 nm and at least one of the emission peaks has Full Width of Half Maximum (FWHM) at least 50 nm or higher. The emission peaks of the LED match well with a plant photosynthesis response spectrum and is therefore particularly suitable for high efficiency artificial lighting.

1. A light emitting component for facilitating plant growth, comprising:
a first Light Emitting Diode (LED) having first and second spectral characteristics including a peak in the wavelength range from 600 to 700 nm, and a peak in the wavelength range from 440 to 500 nm, respectively, the first spectral characteristics being arranged to exhibit a full width of half maximum of at least 50 nm or more, and the second spectral characteristics having a maximum of 50 nm full width of half maximum; and an up-conversion unit including a material configured to provide that all or part of an emission at a frequency of 600-800 nm is generated using a whole or partial wavelength up-conversion of radiation power of the first Light Emitting Diode, the up-conversion unit providing that all or part of an emission at wavelengths of 500-600 nm is arranged to be reduced below an intensity in a 400-500 nm band and below an intensity in a 600-700 nm band.
