Abstract (en)
[origin: WO2014166873A2] The invention relates to devices (1, 11) having a variably adjustable light color and to methods for adjusting the light color of a lighting device (1, 11). In a first concept of the invention, the wavelength of light from a plurality of excitation light sources (2, 3, 4) in a lighting device (1) is converted at least partially by a plurality of color-conversion means (6, 7, 8). The color-conversion means (6, 7, 8) are matched to the wavelengths λ2, λ3, λ4 of the excitation light sources (2, 3, 4). In a second concept of the invention, the wavelength of light from an excitation light source (12) is converted by either a first color-conversion means (6) or a second color-conversion means (7), wherein the color-conversion means (6, 7) can be switched.
