Title:
WAVELENGTH CONVERSION DEVICE, LIGHT-EMITTING DEVICE AND PROJECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/173525
Kind Code:
A1
Abstract:
A wavelength conversion device, comprising a light-emitting layer (110) and a reflecting layer (120) which are arranged in a stacking way, the light-emitting layer (110) comprising a first photoluminescent material and a first binding agent, and the reflecting layer (120) comprising a second photoluminescent material, a second binding agent and reflective particles; light emitted from the reflecting layer (120) emerges completely through the light-emitting layer (110); and the light-emitting layer (110) and the reflecting layer (120) are directly connected to each other or are connected to each other by means of a sintered layer. Also provided are a light-emitting device and a projecting device.
