摘要
A lighting configuration for providing improved vision acuity includes a first light source emitting light having a first wavelength peak in the range from 500 to 530 nm; a second light source emitting light having a second wavelength peak in the range from 600 to 640 nm; and a third light source emitting light having a third wavelength peak in the range from 440 to 460 nm. The radiated power at 555 nm is less than 15% of the radiated power at the wavelength of the second wavelength peak. The light configurations are characterized by an S/P ratio between 2 and 5. Optionally the radiated power at 480 nm is at least 20% of the second wavelength peak. The light sources used in the lighting configuration can be LEDs, preferably LEDs that are substantially free of a color conversion layer.
