Title:
LIGHT SOURCE DEVICE AND PROTECTION-TYPE VIDEO DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/137749
Kind Code:
A1
Abstract:
A light source device of the present disclosure comprises: a first light emitting device that has a plurality of first solid-state light emitting elements arranged in a two-dimensional array at regular intervals; a second light emitting device that has a plurality of second solid-state light emitting elements arranged in a two-dimensional array at regular intervals; and a first photosynthetic plate that has a first region in which light beams, of the plurality of first solid-state light emitting elements and emitted from the light emitting device, are transmitted, and a second region in which light beams, of the plurality of second solid-state light emitting elements and emitted from the second light emitting device, are reflected. Point images of the light beams from the plurality of first solid-state light emitting elements and the plurality of second solid-state light emitting elements via the first photosynthetic plate form the closest packing array.
