Abstract:
An LED module includes a substrate including a main surface and a rear surface that are opposed to each other. The LED module also includes a plurality of LED chips arranged on the main surface, a drive circuit chip that is provided on the substrate and that is provided for driving the plurality of LED chips, a first heat dissipater that is provided on the rear surface and that overlaps the plurality of LED chips as viewed in the thickness direction of the substrate, and a second heat dissipator that is provided at a position closer to the drive circuit chip than the first heat dissipater is. The second head dissipater has a thickness greater than that of the first heat dissipater. The LED module emits a uniform amount of light and color.
