Abstract
In a lighting device that can change the direction of light by rotating a light control component, excellent glare-free performance is achieved. [Solution] The lighting device 1 comprises a light source 10, a reflector 20, and a cone 30. The light source 10 and the reflector 20 are configured to be rotatable relative to the cone 30 with an axis perpendicular to the optical axis α as the axis of rotation. The reflector 20 expands in diameter from the light inlet 21 towards the light outlet 22 so that its inner diameter is maximized at the light outlet 22, and a portion of the reflector 20 is inserted into the cylinder of the cone 30 so that at least a portion of the light outlet 22 is located inside the cylinder of the cone 30. The reflector 20 and the cone 30 are configured such that light emitted from the light outlet 22 passes through the cylinder of the cone 30 without substantially hitting the inner surface of the cone 30.
