Title:
PROJECTION SYSTEM AND LIGHT EMITTING DEVICE THEREOF
Document Type and Number:
Japanese Patent JP2018151635
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a projection system and a light emitting device for reducing a cost to improve efficiency.SOLUTION: A light emitting device comprises: an excitation light source 71 for generating excitation light; and a wavelength conversion device 72 including a wavelength conversion layer 722 for converting at least a part of the excitation light into converted light. The converted light is wide-band light, or the converted light is mixed with a part of excitation light not converted by the wavelength conversion layer 722 to form the wide-band light. The light emitting device further comprises: a driving device 73 for enabling the excitation light to move relative to the wavelength conversion layer 722; and a light splitting device for splitting the wide-band light into at least two kinds of monochromatic light for propagating along different paths.SELECTED DRAWING: Figure 7
