Abstract
A lamp includes a plurality of semiconductor light-emitting elements arrayed linearly, an aluminum substrate on which the plurality of light-emitting elements are mounted, and a linear light wavelength conversion member disposed separated from light-emitting surfaces of the plurality of light-emitting elements. The aluminum substrate includes a circuit formed such as to be able to switch on/off the plurality of light-emitting elements, as grouped into a plurality of sets, on a per-set basis in which the sets are composed of either one or a plurality of the light-emitting elements.
