Abstract
The present invention relates to a color conversion device (204) for a light output device (102) emitting light within a first wavelength range, comprising a first wavelength converting element (106) adapted to receive light emitted by the light output device (102) and to output light at a second wavelength range, and a second wavelength converting element (108) arranged to receive the light outputted from the first wavelength converting element (108) and to output light at a third wavelength range, wherein one of the first or the second wavelength converting element (106, 108) is arranged to partly cover the other one of the first or the second wavelength converting element (106, 108), thereby allowing for the color conversion device (204) to output light within the second and third wavelength ranges. By only partly cover either the first wavelength converting element (106) with the second wavelength converting element, or only partly cover the second wavelength converting element (108) with the first wavelength converting element (106), it is possible to achieve a higher color rendering index (CRI) as not all of the light emitted by the light output device (102) is filtered by both the first and the second wavelength converting element (106, 108).
