Title:
LIGHT EMITTING DEVICE AND PROJECTION DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/161932
Kind Code:
A1
Abstract:
A light emitting device and a projection display apparatus. The light emitting device comprises: an excitation light source (11), used for emitting excitation light; a compensation light source (12), used for emitting compensation light having a spectral range different from that of the excitation light; and a wavelength conversion device (13), disposed in a transmission path of the excitation light and the compensation light and used for outputting sequential light under alternate irradiation of the excitation light source (11) and the compensation light source (12), the sequential light comprising at least one type of excited light and the compensation light. The compensation light has spectral overlap with at least one type of excited light in the at least one type of excited light, so as to greatly improve the brightness of the light emitting device and the utilization efficiency of light in the light emitting device.
