<p>A lighting device comprises a light emitting part including a plurality of light emitting elements; a luminance setting part that sets luminance to be within a predetermined luminance range; and a control part controlling light emission of the plurality of light emitting elements according to the luminance set by the luminance setting part. If the luminance set by the luminance setting part is less than or equal to threshold luminance that is less than the upper limit of the luminance range, the control part controls a part of light emitting elements of the plurality of light emitting elements not to emit light and intermittently changes the part of light emitting elements in the non-light emission state among the plurality of light emitting elements.</p> |
