Abstract
A lighting apparatus is provided with a light source unit including laser diode elements, a collimating lens, and at least one optical element changing only a predetermined one-axis direction of a traveling direction of the substantially parallel light. When the substantially parallel light is incident on a first surface of the optical element, the optical element reflects the substantially parallel light by a second surface to change only the one-axis direction of the traveling direction of the substantially parallel light, and emits an inclined light flux inclined from the substantially parallel light. An aspect ratio of a screen configured by spot lights from the light source unit is changed to an aspect ratio on a cross section of a predetermined position in a traveling direction of the inclined light flux.
