USE OF PHOSPHOR LED'S FOR FINE TUNING THE PERFORMANCE OF A LIGHTING ASSEMBLY

摘要

Disclosed is a lighting assembly comprising light emitting diodes (LEDs). A first group of at least one LED emits light having a peak wavelength in the range of from 550 to 620 nm; a second group of at least one LED emits light having a peak wavelength in the range of from 505 to 550 nm; and a third group of at least one phosphor-comprising LED having a peak wavelength in the range of from 450 to 505 nm. The former two groups have a light intensity at least twice that of the third group. In an alternate embodiment a lighting assembly for utility lighting comprises a first group of at least one LED having a peak wavelength in the range of from 480 to 530 nm, and a second group of at least one phosphor comprising LED.
