LIGHT-EMITTING DEVICE

摘要

Disclosed is a light-emitting device wherein self-absorption of light among phosphors is reduced, the light-emitting efficiency of the phosphors is increased by reducing the absorption of fluorescence by a sealing resin, and wherein optical scattering of the phosphor is prevented and the light extraction efficiency from a phosphor layer is increased. The disclosed light-emitting device is configured to have a semiconductor light-emitting element and a phosphor layer, the phosphor layer being a compact phosphor layer wherein the particle size distribution of the phosphor contained in said layer, and the filling ratio of the phosphor contained in said layer are specified values.
