Patent number: 10374134Abstract: A light emitting device includes: a covering member including a first light-reflective member having a through-hole, and a light-transmissive resin disposed in the through-hole; a light-emitting element arranged to face the light-transmissive resin; a second light-reflective member arranged to face the first light-reflective member around the light-emitting element, the second light-reflective member covering a lateral surface of the light-emitting element; and a bonding member bonding the light-transmissive resin and the light-emitting element, the bonding member covering at least a part of the lateral surface of the light-emitting element. The light-transmissive resin contains a wavelength-conversion material distributed predominantly on either (i) a side of a lower surface of the light-transmissive resin facing the light-emitting element, or (ii) a side of an upper surface of the light-transmissive resin apart from the light-emitting element.Type: GrantFiled: May 27, 2016Date of Patent: August 6, 2019Assignee: NICHIA CORPORATIONInventors: Tadao Hayashi, Teruhito Azuma, Suguru Beppu, Kunihiro Izuno, Tsuyoshi Okahisa

Patent number: 10357927Abstract: A light emitting device includes a light emitting element having an upper face and lateral faces; a light transmissive member covering at least a portion of the upper face of the light emitting element and transmitting light emitted from the light emitting element; a first reflector covering at least a portion of lateral faces of the light transmissive member; and a second reflector covering the lateral faces of the light emitting element. The first reflector includes a first bottom face and a second bottom face. A plane in which the first bottom face of the first reflector extends is different than a plane in which a lower face of the light transmissive member extends. The second bottom face of the first reflector is located inward of the first bottom face of the first reflector, and is coplanar with the lower face of the light transmissive member. The first bottom face of the first reflector is covered by and in contact with the second reflector.Type: GrantFiled: May 31, 2016Date of Patent: July 23, 2019Assignee: NICHIA CORPORATIONInventors: Teruhito Azuma, Toru Hashimoto, Tadao Morino
