US Patent 10355181 Light-emitting device, integrated light-emitting device, and light-emitting module

A light-emitting device includes: a base member having a conductive pattern; a light-emitting element arranged on the base member so as to be electrically connected to the conductive pattern; and a dielectric multi-layer film located on an upper surface of the light-emitting element. The dielectric multi-layer film has a first spectral reflectivity in an emission peak wavelength region of the light-emitting element and a second spectral reflectivity in a region that is located at a longer wavelength side of the emission peak wavelength region by 50 nm, and the second spectral reflectivity is greater by 10% or more than the first spectral reflectivity.
