Title:
PLANAR LIGHT-EMITTING BODY, AND LIGHTING DEVICE AND BUILDING MATERIAL USING SAID PLANAR LIGHT-EMITTING BODY
Document Type and Number:
WIPO Patent Application WO/2015/097965
Kind Code:
A1
Abstract:
This planar light-emitting body (100) contains a planar light-emitting section (10), a variable light-scattering section (20), and a variable light-reflecting section (30). The planar light-emitting section (10) comprises a light-transmitting organic electroluminescent element. The degree to which the variable light-scattering section (20) scatters light can be changed, as can the degree to which the variable light-reflecting section (30) reflects light. The planar light-emitting body (100) has a first surface (F1), which is designed so as to extract light from the planar light-emitting section (10), and a second surface (F2) on the opposite side from said first surface (F1). The variable light-scattering section (20), the planar light-emitting section (10), and the variable light-reflecting section (30) are laid out between the first surface (F1) and the second surface (F2) in the thickness direction. The variable light-reflecting section (30) is closer to the second surface (F2) than either the planar light-emitting section (10) or the variable light-scattering section (20) is.
