摘要:
A light-emitting device (2) including a light-emitting element (2a), a first phosphor (2b), and a second phosphor (2c). The light-emitting element (2a) emits light L1 having a wavelength range within the visible region. Upon receipt of the light L1, or light L3 originating from the second phosphor (2c), the first phosphor (2b) emits light L2 having a wavelength range, which differs from that of the first light L1 and the third light L3, but falls within the visible region. Upon receipt of a specific wavelength component (ultraviolet light, or the like) included in external light, the second phosphor (2c) generates the light L3 whose wavelength range is substantially the same as that of the light L1, thereby radiating the first phosphor (2b) with the light L3.

摘要:
A light emitting module has a plurality of light emitting elements that emit ultraviolet radiation or short-wavelength visible light mounted on a support substrate in a predetermined two-dimensional pattern, and a luminescent material having resin that contains at least one or more types of luminescent materials that are excited to emit visible light by the ultraviolet radiation or short-wavelength visible emitted by the light emitting element. The plurality of light emitting elements are connected together into a line by the luminescent material containing resin.
