Light emitting device

A light emitting device comprising:

• a bulb having a side surface defining a hollow space therein;
• a board elongated longer in a first direction than in a second direction perpendicular to the first direction;
• a plurality of light emitting elements mounted on the board, each of the plurality of light emitting elements having an upper surface and a lower surface opposite to the upper surface, the lower surface mounted on the board;
• a plurality of metal plates electrically connected to the plurality of light emitting elements, the plurality of metal plates including a first metal plate and a second metal plate;
• a plurality of leads electrically connected to the plurality of metal plates;
• and
• a wavelength conversion member adapted to convert wavelength of light emitted from the plurality of light emitting elements, the wavelength conversion member covering the plurality of light emitting elements and a portion of each of the metal plates, wherein
• the board, the plurality of light emitting elements, the plurality of metal plates and the wavelength conversion member are disposed in the hollow space of the bulb,
• the first metal plate, the board, and the second metal plate are arrayed along the first direction,
• the plurality of light emitting elements are arrayed on the board along the first direction,
• the upper surface of each of the plurality of light emitting elements faces the side surface of the bulb, and
• the first metal plate and one of the plurality of light emitting elements closest to the first metal plate are electrically connected with wire.
