  • Publication number: 20180245763
    Abstract: A lighting apparatus includes a light source unit and a light guide unit. The light source unit includes a light source that emits light. The light guide unit includes a reflective surface that changes a traveling direction of the light to produce reflected light, and guides the light emitted from the light source unit to make the light reach the reflective surface. A plurality of the reflective surfaces-is provided. The light source unit selects one of the plurality of reflective surfaces and emits the light to the selected reflective surface. Thus it is possible to prevent an increase in the number of places where light sources are disposed and to change light-emitting regions on the light guide unit.
