Abstract
Official abstract text for this publication.
A light emitting device includes a light emitting element having a first face positioned on an emission face side of the light emitting device, a second face opposing the first face, and lateral faces disposed between the first face and the second face, a light transmissive member formed from a resin-containing material, covering at least a portion of the lateral faces of the light emitting element and having a first face positioned on the emission face side, a covering member covering an exterior of the light transmissive member and having a first face positioned on the emission face side, a wavelength converting member covering the first face of the light emitting element, the first face of the light transmissive member, and the first face of the covering member, and a light reflective film including a first reflective film portion made of an inorganic material disposed between the exterior of the light transmissive member and the covering member, and a second reflective film portion made of an inorganic material disposed between the first face of the covering member and the wavelength converting member.
First claim
Opening claim text (preview).
What is claimed is: 1 . A light emitting device comprising: a light emitting element having a first face positioned on an emission face side of the light emitting device, a second face opposing the first face, and lateral faces disposed between the first face and the second face; a light transmissive member formed from a resin-containing material, covering at least a portion of the lateral faces of the light emitting element; a wavelength converting member covering the first face of the light emitting element; a first covering member covering lateral faces of the wavelength converting member; a second covering member covering an exterior of the light transmissive member and separating from the wavelength converting member; and a light reflective film being in contact with an inner surface of the second covering member. 2 . The light emitting device according to claim 1 , wherein: the second covering member has an upper surface positioned lower than the first face of the light emitting element. 3 . The light emitting device according to claim 1 , wherein: an outer surface of the first covering member is flush with an outer surface of the second covering member. 4 . The light emitting device according to claim 1 , wherein: a thickness of the first covering member is the same as a thickness of the wavelength converting member. 5 . The light emitting device according to claim 1 , wherein: the inner surface of the second covering member comprises a tilted surface, and a portion of the wavelength converting member is positioned on the tilted surface through the light transmissive member. 6 . The light emitting device according to claim 1 , wherein: the light reflective film is in contact with the wavelength converting member. 7 . The light emitting device according to claim 1 , wherein: the light emitting element has a pair of electrodes on the second face, and the light reflective film is in contact with the pair of the electrodes. 8 . The light emitting device according to claim 1 , wherein: a portion of the light reflective film is positioned lower than the light emitting element. 9 . The light emitting device according to claim 1 , wherein: the light transmissive member is disposed between the first face of the light emitting element and the wavelength converting member. 10 . The light emitting device according to claim 1 , wherein: the light reflective film is made of an inorganic material. 11 . The light emitting device according to claim 1 , wherein: the light reflective film is made of an insulating material. 12 . The light emitting device according to claim 1 , wherein: the light reflective film is made of an metal material. 13 . The light emitting device according to claim 1 , wherein: the light reflective film includes a titanium oxide.
