Title: LIGHTING DEVICE
Abstract:
A lighting device (105) is provided with a light source unit (1) and a light guiding unit (370). The light source unit (1) includes a light source (1a) for emitting first light. The light guiding unit (370) includes a reflection surface (374) for changing the traveling direction of light to generate reflected light, and guides the light emitted from the light source unit (1) to the reflection surface (374). A plurality of reflection surfaces (374) are provided. The light source unit (1) selectively irradiates the plurality of reflection surfaces (374) with the emitted light. Consequently, an increase in the number of places where the light source (1a) is disposed is suppressed, and a light emission region (5) on the light guiding unit (370) can be changed.
