Abstract:
A light emitting device is a light emitting device using light emitting elements and includes: a substrate; a resin frame provided circularly on the substrate; a resin wall provided on the substrate so as to partition an area surrounded by the resin frame into 2 zones; light-emitting sections (a first light-emitting section: blue LEDs+red fluorescent material, a second light-emitting section: blue LEDs+yellow fluorescent material) provided in the respective zones, each of which light-emitting sections includes at least one light emitting element; and first and second anode electrodes and a cathode electrode provided so that each of the light-emitting sections receives current via a corresponding anode electrode and the cathode electrode, the light-emitting sections emitting respective pieces of light each having at least one color, which respective pieces of light have different colors from each other, the first and second anode electrodes being electrically connected to the first and second light-emitting sections, respectively. With the arrangement, which can increase an integration degree, it is possible to achieve a high color rendering property and an excellent color mixing property, to easily adjust a chromaticity, and to easily generate light with a desired chromaticity.
