Patent number: 10396257Abstract: A method of manufacturing a light emitting device include providing a mold with a mold recess having a bottom and an inner peripheral surface that is connected to the bottom. The bottom includes a bottom projection and a bottom recess surrounding the bottom projection to define the bottom projection that has a projection top surface and a projection peripheral surface opposing the inner peripheral surface. A light emitting element is mounted on the bottom projection such that a light extraction surface of the light emitting element faces the projection top surface and such that an outer peripheral surface of the light emitting element opposes the inner peripheral surface of the mold recess. A covering material is provided in the mold recess to cover the inner peripheral surface of the mold recess, the outer peripheral surface of the light emitting element, and the projection peripheral surface.Type: GrantFiled: December 21, 2017Date of Patent: August 27, 2019Assignee: NICHIA CORPORATIONInventor: Shigeki Sajiki

Patent number: 10243118Abstract: A method for manufacturing a light emitting device, includes providing a light emitting element including an electrode-formed surface, a substrate surface opposite to the electrode-formed surface, and a light emitting surface connecting the electrode-formed surface and the substrate surface. A bottom mold including a mounting surface having a protrusion and mold recesses provided on both sides of the protrusion to define the protrusion is provided. The light emitting element is mounted on the protrusion such that the light emitting surface faces the protrusion. A covering material is provided on the mounting surface of the bottom mold to fill the mold recesses and to cover an entirety of the light emitting element except for the light emitting surface. The bottom mold with the protrusion is removed to provide a recess in the covering material. A light-transmissive material is provided in the recess of the covering material.Type: GrantFiled: December 18, 2017Date of Patent: March 26, 2019Assignee: NICHIA CORPORATIONInventor: Shigeki Sajiki

Patent number: 9728688Abstract: A method of manufacturing a light emitting device includes providing a light emitting element, a light extracting surface, and a light emitting element lateral surface. A lower mold has an upper surface and a projected portion. The projected portion has a bottom portion. The projected portion has a projected portion upper surface. The projected portion has a projected portion lateral surface provided between the bottom portion and the projected portion upper surface. The light emitting element is arranged on the projected portion such that the light extracting surface contacts the projected portion upper surface. The projected portion lateral surface and the light emitting element lateral surface are covered with a cover member. The lower mold is removed to provide a recessed portion on the light extracting surface surrounded by a sidewall made of the cover member. A first light-transmissive member is provided in the recessed portion.Type: GrantFiled: June 30, 2016Date of Patent: August 8, 2017Assignee: NICHIA CORPORATIONInventor: Shigeki Sajiki
