Abstract:
A lighting device, in various embodiments, for generating a light emission, has a light source designed to generate light with a first dominant wavelength, a first converter designed to absorb the light generated by the light source and to emit light with a second dominant wavelength, which is longer than the first dominant wavelength, and a second converter designed to absorb a portion of the light emitted by the first converter and to emit light such that the light emission has a third dominant wavelength, which is longer than the second dominant wavelength.
