LIGHT EMITTING DEVICE AND ILLUMINATION APPARATUS INCLUDING SAME

摘要

A light emitting device includes a plurality of solid-state light emitting elements mounted on a substrate; and a wavelength converting unit covering the solid-state light emitting elements, the wavelength converting unit containing fluorescent materials. The solid-state light emitting elements include inner solid-state light emitting elements arranged in a central position of the substrate and outer solid-state light emitting elements arranged outwardly of the inner solid-state light emitting elements, and the wavelength converting unit is configured such that a probability that light propagating through the wavelength converting unit is brought into contact with the fluorescent materials in a portion of the wavelength converting unit covering the outer solid-state light emitting elements is lower than a probability that light propagating through the wavelength converting unit is brought into contact with the fluorescent materials in other portions.
