Abstract:
1. A light-emitting device comprising: a board; a plurality of 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 are driven in parallel; and a plurality of capacitors that each include a first electrode and a second electrode arranged in a line parallel to a short-side direction of the board, the plurality of capacitors being arrayed in the longitudinal direction of the board along the array of the plurality of light-emitting chips such that the first electrodes and the second electrodes of adjacent capacitors are alternately positioned in an inverted relationship relative to each other, the first electrode of each capacitor being connected to the first potential for the light-emitting chips, and the second electrode of each capacitor being connected to the second potential for the light-emitting chips.
