LED module for generating white light having a plurality of white-light LEDs including at least one LED with a central wavelength of between 495 nm and 507 nm, at least one LED with a central wavelength of between 511 nm and 529 nm, at least one LED with a central wavelength of between 586 nm and 602 nm, and at least one LED with a central wavelength of between 618 nm and 630 nm.
1. An LED module for generating white light, comprising:
a plurality of white-light LEDs,
at least one color LED with a central wavelength of between 495 nm and 507 nm,
at least one color LED with a central wavelength of between 511 nm and 529 nm,
at least one color LED with a central wavelength of between 586 nm and 602 nm, and
at least one color LED with a central wavelength of between 618 nm and 630 nm,
