Abstract

The invention describes a light conversion device having a light converter, which is adapted to convert primary light to converted light, so that a peak emission wavelength of the converted light is in a longer wavelength range than a peak emission wavelength of the primary light. The light conversion device also has a reflective structure coupled to at least a part of a coupling surface of the light converter, where the reflective structure is a narrowband reflector arranged to reflect at least some of the primary light impinging on the reflective structure and to transmit at least some of the converted light impinging on the reflective structure.
