Title:
LIGHT EMITTING ELEMENT, REFERENCE LIGHT SOURCE, AND PHOSPHOR OBSERVATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/098796
Kind Code:
A1
Abstract:
In the present invention, light, the emission angle distribution of which is either a Lambert emission distribution or an isotropic uniform emission distribution, is extracted from a light extraction opening window. A light emitting element, in which the in-plane distribution of the light intensity of a light extraction surface in the light extraction opening window is uniform, is used as a reference light source when performing measurement of the absolute light volume of weak light emitted from a phosphor which is the object of measurement.
