COMPACT LIGHT ENGINE

A light engine comprises: a wavelength conversion device, receiving source light of a first wavelength range and a first polarisation, generating light of a second wavelength range from a portion of the received source light, at least a portion of the second wavelength range being non-overlapping wi...

Beschreibung
Zusammenfassung:	A light engine comprises: a wavelength conversion device, receiving source light of a first wavelength range and a first polarisation, generating light of a second wavelength range from a portion of the received source light, at least a portion of the second wavelength range being non-overlapping with the first wavelength range, the wavelength conversion device reflects output light comprising the generated light and comprises a polarisation converter that sets at least some of the output light to a second polarisation, different from the first polarisation; and a dichroic element, that receives the reflected output light and directs light of the first polarisation differently from light of the second polarisation.
