Abstract:
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, wherein the the white-light LEDs generate white light of a first spectrum and the LED module generates white light of a second spectrum by combining light emitted by the white-light LEDs with light emitted by the color LEDs, the first spectrum of white light being different from the second spectrum of white light.
