LIGHT EMITTING DEVICE, ILLUMINATING APPARATUS AND CLEAN ROOM PROVIDED WITH ILLUMINATING APPARATUS

摘要

A light emitting device is provided with a semiconductor light emitting element, a fluorescent material to be excited by light emitted from the semiconductor light emitting element, and a sealing resin which has the fluorescent material and covers the semiconductor light emitting element. In the light emitting device, a specific wavelength component is suppressed so that a photosensitive material which reacts to a specific wavelength does not react due to the fluorescent material contained in the sealing resin. An illuminating apparatus is provided with a plurality of the semiconductor light emitting elements. The illuminating apparatus has a control section for suppressing the specific wavelength to prevent the photosensitive material which reacts to the specific wavelength from being exposed to light. A clean room is provided with such illuminating apparatus.
