Abstract
The present disclosure discloses a light-emitting device and a projection system, comprising: a light source, configured to emit excitation light; a beam-splitting-combining plate disposed in an outgoing light path of the excitation light, and including a beam-splitting portion configured to split the excitation light into a first excitation light and a second excitation light along different propagation paths; a first wavelength conversion device including a first wavelength converting layer configured to absorb the first excitation light to generate first excited light; and a second wavelength conversion device configured to reflect the second excitation light back to the beam-splitting-combining plate. The beam-splitting-combining plate further includes a beam-combining portion disposed around the beam-splitting portion, and the beam-combining portion is configured to combine the first excited light and the second excitation light respectively reflected to the beam-splitting-combining plate into one beam.
