PROBLEM TO BE SOLVED: To achieve a reduction in a cost by avoiding an increase in electronic components including a light emission source and the necessity of electronic control in producing movements of light in interior decoration of vehicles, and to eliminate a disconnection or the like of wiring due to the movement of the light emission source.SOLUTION: A light control device for producing movements of light includes a light emission source 14 fixed on a base plate 10 and a light guiding body 22 which is assembled to be movable with respect to the base plate, and where the light emitted by the light emission source enters. The light guiding body has a reflection surface 22a which specularly reflects the incident light from the light emission source 14 to release output light, and a plurality of reflection points are set on the reflection surface. The light control device is configured that these reflection points are selected in order by the movement of the light guiding body 22 to release the output light only at the selected reflection point. |
