Abstract
A lighting device includes light sources, a light source board, and a casing. The light source board includes a board body portion having a substantially circular outer edge where the light sources are arranged at intervals in a substantially annular shape such that each light source emits light toward a center, an extended portion extending inward from the board body portion, and a trace portion electrically connected to each light source. The casing includes a tubular-shaped side wall portion surrounding the light sources, and a bottom portion disposed opposite the board body portion and having an exit hole therethrough through which the extended portion is inserted and the distal end of the extended portion is extended outside.
