Abstract:
A light-emitting device includes a base member, a light-emitting element, and a cover. The cover has a lateral portion surrounding a periphery of the light-emitting element and an upper portion arranged above the light-emitting element. The cover includes a wavelength conversion member and a light-shielding member. The wavelength conversion member has an incident surface where the light emitted from the light-emitting element in the lateral direction is incident, at least a part of the wavelength conversion member constituting at least a part of the upper portion of the cover. A straight line, which passes through a light-emitting point of the light-emitting element and is parallel to an optical axis direction, passes through a part of the light-shielding member. At least the part of the light-shielding member is located, relative to the wavelength conversion member, on a side opposite from the light-emitting element in the optical axis direction.
