Patent ID: 11047549

Abstract:
A light-emitting device includes an optical member including first and second light emitting elements, first and second light condenser portions, and a light guide portion. The first light condenser portion is disposed at a position corresponding to the first light-emitting element, and condenses a portion of light emitted from the first light-emitting element. The second light condenser portion surrounds the first light condenser portion, and condenses a portion of the light that is not incident to the first light condenser portion among the light emitted from the first light-emitting element. The light guide portion is disposed at a periphery of the second light condenser portion and at a position corresponding to the second light-emitting element, and guides light emitted from the second light-emitting element by causing total reflection in an interior of the light guide portion. A full width at half maximum of light exiting from the light guide portion is larger than a full width at half maximum of light exiting from the first light condenser portion.
