  • Publication number: 20190294005
    Abstract: A light emitting module includes a light transmissive light guiding plate, a light adjustment portion, and a light emitting element. The light guiding plate has a first main surface serving as a light emitting surface which emits light outside, and a second main surface opposite to the first main surface. The second main surface is provided with a recess. The light adjustment portion is disposed in the recess of the light guiding plate. The light emitting element is bonded to the light adjustment portion. The light adjustment portion includes a wavelength conversion portion and a light diffusion portion. The light diffusion portion has a wavelength conversion portion side on which the wavelength conversion portion is bonded. The light diffusion portion is disposed on a bottom of the recess. The wavelength conversion portion is bonded to the light emitting element.

  • Publication number: 20190157528
    Abstract: A light emitting device includes a light emitting surface, a back surface arranged on an opposite side of the light emitting surface, a mounting surface arranged between the light emitting surface and the back surface, and includes a light emitting element, a light shielding member, first and second terminal coating films, and first and second electrically conductive members. The light emitting element has first and second electrodes arranged on the second main surface. The light shielding member covers the lateral surface of the light emitting element and does not cover the first main surface of the light emitting element. The first and second terminal coating films are electrically connected to the first and second electrodes respectively, and arranged continuously on the back surface and the mounting surface of the light emitting device. The first and second electrically conductive members are in contact with the first and second electrodes respectively.

  • Patent number: 10224468
    Abstract: A method of manufacturing a light emitting device includes: arranging first and second light emitting elements, each having a pair of electrodes disposed on a surface opposite to a main light emitting surface, on a base body adjacent to each other with the electrodes facing upward; forming a light shielding member at least covering the electrodes of each of the first and second light emitting elements and a portion between the first and second light emitting elements; forming recesses by removing portions of the light shielding member so that at least a portion of each of the electrodes of the first and second light emitting elements are exposed from the light shielding member; and forming electrically conductive members in the recesses so that each of the electrically conductive members is in contact with a corresponding one of the electrodes of the first and second light emitting elements.

  • Patent number: 9917234
    Abstract: A method of manufacturing a light emitting device includes: arranging a first light emitting element and a second light emitting element, each having a pair of first and second electrodes disposed on a surface opposite to a main light emitting surface, on a base body adjacent to each other with the pair of electrodes facing upward; forming a pair of electrically conductive members each extending between one of the pair of electrodes of the first light emitting element and a corresponding one of the pair of electrodes of the second light emitting element; forming a light shielding member at least covering between the first and second light emitting elements; and cutting the pair of electrically conductive members and the light shielding member between the first and second light emitting elements, along a direction substantially perpendicular to the main light emitting surface of each of the first and second light emitting elements.

  • Patent number: 9368675
    Abstract: A method of manufacturing a light-emitting device includes flattening top portions of solder bumps disposed on a wiring substrate, disposing a light-emitting element on the solder bumps whose top portions are flattened, and heating the solder bumps to be melt and to be fused so as to provide an adhesive with which the light-emitting element is secured on the wiring substrate.
