Abstract

A light emitting device including a bulb having a side surface, a board elongated longer in a first direction than in a second direction perpendicular to the first direction, and a plurality of light emitting elements mounted on the board. Each of the plurality of light emitting elements has an upper surface and a lower surface opposite to the upper surface, where the lower surface is mounted on the board. The device includes a plurality of sets of metal plates and leads electrically connected to the plurality of light emitting elements, and a wavelength conversion member covering the light emitting elements and a portion of each of the metal plates. The board, the light emitting elements, the sets of metal plates and leads, and the wavelength conversion member are disposed in the bulb. The upper surface of each of the light emitting elements faces the side surface of the bulb.
