Abstract: A light-emitting device includes a base member having an upper surface and a recess on an upper surface side; a light-emitting element disposed in the recess and configured to emit ultraviolet light; a light-transmissive member disposed on the upper surface; a first inorganic adhesive member disposed on the light-transmissive member; and a lens bonded to the light-transmissive member with the first inorganic adhesive member. An absolute value of a difference in linear expansion coefficient between the base member and the light-transmissive member is smaller than an absolute value of a difference in linear expansion coefficient between the base member and the lens.

Abstract: A light emitting device includes: a base having an upper face; a light emitting element mounted on the upper face of the base; one or more bonding members disposed on the upper face of the base outward of the light emitting element; a light transmissive member bonded to a portion of the upper face of the base by the one or more bonding members; and a protective film that continuously covers the light emitting element, the upper face of the base, lateral faces of the one or more bonding members, and a lower face of the light transmissive member. A gap is located between the upper face of the base and the lower face of the light transmissive member and configured to allow a space in which the light emitting element is mounted to communicate with an outside of the light emitting device, wherein the gap is defined by the upper face of the base, the lower face of the light transmissive member, and the one or more bonding members.

Abstract: A light emitting device and light emitting module using the same are provided. The light emitting device includes a substrate, a light-emitting element provided on the substrate, and a light transmissive sealing member covering the light-emitting element on the substrate. The light transmissive sealing member includes a body portion and a lens portion that are sequentially disposed from a substrate side.
