Title:
ILLUMINATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/153639
Kind Code:
A1
Abstract:
The invention relates to the technical field of illumination, and discloses an illumination system, comprising: a light-emitting device, a spatial polarization distribution modulation device and a lens, wherein the light-emitting device is used for emitting light of a light source , and the light of the light source at least comprises first light of a first polarization state; the spatial polarization distribution modulation device receives the first light in at least part of a time period and converts the at least part of the first light of the first polarization state to the first light of a second polarization state, and the spatial polarization distribution modulation device can simultaneously emit the first light of the first polarization state and the second polarization state; and the first light emitted by the spatial polarization distribution modulation device constitutes at least part image light, and the lens is used for projecting the image light to form illumination light. By means of the present invention, without changing the spatial distribution of illumination light, the polarization distribution of the illumination light is simply patterned, so that light receivers with different requirements can configure a polarization filter device according to the requirements to receive different illumination information, thereby improving the user experience.
