Abstract: A lighting device includes an electricity storage electrically connected in parallel with a solid light source, a switching circuit that produces a current to supply the current to the electricity storage, and a control circuit that controls, according to a dimming level, burst dimming by controlling the switching circuit so that the solid light source is lit intermittently. When the dimming level is a threshold level or more, the control circuit sets an electricity storage capacity of the electricity storage to a first capacity, and sets a frequency by the burst dimming to a first frequency. When the dimming level is below the threshold level, the control circuit sets the electricity storage capacity to a second capacity smaller than the first capacity, and sets the frequency by the burst dimming to a second frequency higher than the first frequency.
