Document Type and Number:
WIPO Patent Application WO/2014/132542
Kind Code:
A1
Abstract:
A light emitting element (100) is provided with: an LED element (1); a resin section, which contains phosphor, and which seals the LED element, said phosphor absorbing a part of light emitted from the LED element, performing wavelength conversion, and emitting the light; and a reflecting film (3), which contains an inorganic oxide, and which is formed on the surface of the resin section. The reflecting film has wavelength dependence in light transmission characteristics, and a refractive index of the reflecting film is larger than that of the resin section. As a result, the light emitting element capable of efficiently outputting white light having desired chromatic characteristics is provided.
