    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.

    Abstract: The light emitting device includes a light emitting element, a wavelength converter, and a light guider. 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. 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 includes first and second wavelength converter parts. The first wavelength converter part faces the element upper surface and has a first thickness. The second wavelength converter part does not face the element upper surface and has a second thickness thinner than the first thickness.

    Abstract: A light emitting device includes: a base portion comprising: an upward-facing surface, and a frame defining an inner lateral surface; a plurality of semiconductor laser elements arranged on the upward-facing surface and surrounded by the frame; a cover portion supported by the frame and disposed above the plurality of semiconductor laser elements; and a protrusion extending from a lower surface of the cover portion toward the upward-facing surface. Light emitted from each of the plurality of semiconductor laser elements is incident on a lateral surface of the protrusion, passes through the protrusion, is reflected at the boundary surface, and is transmitted through the cover portion.

    Abstract: A light emitting module includes a light emitting device including first to sixth electrodes and a holder including first to sixth terminals. An insulator body of the holder at least partially surrounds the light emitting device in a plan view with the light emitting device being interposed between a first inner edge and a second inner edge of the insulator body, and a third inner edge linking the first and second inner edges. The first terminal projects from a third inner edge and is connected to the first electrode. The second and third terminals project from the first inner edge and are connected to the second and third electrodes, respectively. The fourth terminal projects from the third inner edge and connected to the fourth electrode. The fifth and sixth terminals project from the second inner edge and are connected to the fifth and sixth electrodes, respectively.
