Toshiki NISHIHAMA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10714663
    Abstract: A method of manufacturing a light emitting device, includes providing a light emitting element having an element upper surface, an element lower surface opposite to the element upper surface in a thickness direction of the light emitting element, and an element side surface between the element upper surface and the element lower surface. A wavelength converter having a converter lower surface is provided. The wavelength converter is joined to the light emitting element using an adhesive so that the converter lower surface faces the element upper surface. The converter lower surface has an exposed region that does not face the element upper surface viewed along the thickness direction. The adhesive covers the element side surface and the exposed region.
    Type: Grant

  • Patent number: 9947841
    Abstract: A light emitting device includes a light emitting element, a wavelength converter, a light transmissive member, a light guider, and a light transmitting layer. The light emitting element has an element upper surface, an element lower surface, and an element side surface. The wavelength converter has a converter lower surface. The wavelength is provided to be connected to the light emitting element such that the converter lower surface faces the element upper surface. The converter lower surface has an exposed region that does not face the element upper surface. The light guider guides light from the light emitting element to the wavelength converter. The light guider covers the element side surface and the exposed region. The wavelength converter has a converter upper surface. The light transmitting layer has a layer lower surface facing the converter upper surface. The converter upper surface is smaller than the layer lower surface.
