    摘要： A light emitting device includes: an excitation light emitting source (71) for generating excitation light; a wavelength conversion device (72) comprising a wavelength conversion layer, the wavelength conversion layer (722) converting at least a part of the excitation light into converted light, and the converted light being light with a wide spectrum, or the converted light being mixed with excitation light not converted by the wavelength conversion layer (722) to form light with a wide spectrum; a driving device (73) for enabling the excitation light to move relative to the wavelength conversion layer; and a light splitting device (62) for splitting the light with the wide spectrum into at least two kinds of monochromatic light propagating along different paths. Further provided is a projection system comprising the light emitting device.

    摘要： An image projection image for projecting an image on a screen includes a light source, a scanning mirror and a prism. The light source includes laser diodes for emitting beams of different wavelengths. The scanning mirror reflects the beams radiated from the light source and projects the reflected beams. The prism is disposed at the rear of the scanning mirror to decenter the beams via the scanning mirror based on the wavelengths. In the image projection apparatus, the laser diodes are fixed to be vertically spaced apart from a reference height, corresponding to the wavelengths of the beams.
