User interface with circular light guided ring with adaptive appearance depending on function
First Claim
1. A control device for controlling a plurality of properties of light emitted from a light source, the device comprising:
- a touch-sensitive user interface, for visually indicating a range of available values representing at least one property and to enable a user to control said at least one property on the basis of a location touched on said touch-sensitive user interface, thereby providing the control device with user input;
a communication unit for adjusting said at least one property by means of communicating, to the light source, control signals corresponding to said user input;
a plurality of activation areas, each activation area being associated with at least one of said plurality of properties and being adapted, when activated, to cause said control device to enable the user to control the property associated with said activated activation area with said touch-sensitive user interface;
a user interface visual appearance variation unit adapted to adjust the visual appearance of the user interface on the basis of the respective property associated with the activation area which includes a substantially circular and approximately planar light guide having a plurality of recesses, each of the recesses arranged to receive a light emitting element.

Abstract
The present invention relates to a control device adapted to control properties of light emitted from a light source. The control device may comprise a touch-sensitive user interface adapted to visually indicate a range of available values representing at least one of the properties and to enable a user to control the represented property on the basis of a location touched on the touch-sensitive user interface. The controlled property may be adjusted by means of a communication unit adapted to communicate to the light source control signals corresponding to user input. The control device may be adapted to enable the user to control a property associated with an activation area with the user interface upon activation of the activation area by the user.

12. A control device to control properties of light emitting from a light source, comprising:
-
a touch sensitive user interface operable to visually indicate a range of available values representing a plurality of properties and enable a user to control each of the plurality of properties on the basis of a location touched on the touch sensitive user interface; a control unit for adjusting each of the plurality of properties and operably connected to the light source by transmitting control signals to the light source corresponding to the location touched on the touch sensitive user interface representing user input; a light guide forming at least a part of the touch sensitive user interface operably connected to a printed circuit board and positioned relative to a plurality of light emitting elements, each of the light emitting elements positioned in one of a plurality of recesses formed in the light guide such that each of the light emitting elements emit light radially into the light guide to visually indicate a range of available values representing a selected one of the plurality of properties; wherein spacing between adjacent light emitting elements is less than spacing between other light emitting elements to indicate the visual contrast at a hard transition of the selected one of the plurality of properties.
