Abstract
A lighting device includes a first light emitting part including a first light source part and a first optical part that includes a first reflecting part and a second reflecting part. A first direction from the first reflecting part to the second reflecting part crosses a second direction from the first light source part to the second reflecting part. A direction from the first light source part to the first reflecting part is along a first plane which includes the first direction and the second direction, and crosses the second direction. A distance between the first reflecting part and the first light source part is larger than a distance between the second reflecting part and the first light source part. A light distribution angle of a first-reflecting-part light in the first plane is larger than the light distribution angle of the second-reflecting-part light in the first plane.
