Lighting device with user interface for light control
First Claim
1. A lighting device comprising a lighting unit and a user interface for controlling the color and/or luminous intensity of light emitted by the lighting unit, said user interface comprising:
- a physical object shaped as a polyhedron having a plurality of sides, each side being associated with a predetermined color of light such that, in operation, the user interface generates an output signal for controlling the lighting unit to emit the light of a desired color and/or luminous intensity based, at least in part, on orientation and/or rotation of the physical object with at least three degrees of freedom.

Abstract
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).

18. A method for controlling color and/or luminous intensity of light emitted by a lighting device comprising a lighting unit and a user interface, the user interface comprising a physical object shaped as a polyhedron having a plurality of sides, each side being associated with a predetermined color of light, the method comprising:
-
orienting the physical object with at least three degrees of freedom to select a desired color and/or intensity of light, rotating the physical object to generate an output signal for controlling the lighting unit, and transmitting the output signal to the processing unit to control the lighting unit to emit the light of desired color and/or intensity.
