The present invention relates to a lighting device (1) comprising a lighting unit (2) and a user interface (3) for controlling the lighting color and/or intensity of the lighting unit (2). The user interface (3) comprises a physical object (4), which is shaped as a polyhedron, for instance a cube. Orienting the physical object (4), i.e. choosing which side is up, serves to select the color, and rotating the physical object (4) about the side on which it rests serves to change the intensity setting. The user interface (3) generates an output signal, which is the input for a processing unit (9). This processing unit (9) converts this signal into a driving signal suitable for controlling the lighting unit (2).
