Abstract:
A light-emitting device includes: a board; plural light-emitting chips that are one-dimensionally arrayed in a longitudinal direction of the board and that are connected to a first potential and a second potential; and plural capacitors that each include a first electrode and a second electrode arranged in a short-side direction of the board, and that are arrayed in the longitudinal direction of the board so that the first electrode and the second electrode are alternately positioned between each adjacent two of the capacitors. The first electrode is connected to the first potential for the light-emitting chips, and the second electrode is connected to the second potential for the light-emitting chips.
