Abstract
A light emitting device includes a board, light emitting element chips, a wavelength conversion member, a transparent bulb, support leads, and a support base. The board has a first surface and a second surface. The second surface is an opposite side to the first surface. The light emitting element chips are mounted on the first surface side. The wavelength conversion member is formed unitarily with a transparent member. The transparent bulb encloses the board and the light emitting element chips. The support leads secure the light emitting element chips inside the transparent bulb. The support base can be threadedly engaged with a conventional light bulb socket along a socket axis. The wavelength conversion member is provided on a first surface side and a second surface side, and is elongated in a longitudinal direction. The light emitting element chips is aligned along a line that extends in the longitudinal direction.
