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 user interface may comprise at least one discontinuity-indicating element adapted to visually indicate a step discontinuity in the range of available values representing the at least one property.

Lighting control device having a touch sensitive user interface

A method of providing a user interface for controlling a system () includes observing a presence of a body or body part of a user in a certain environment of a device (-). At least a perceptible part () of the user interface is made available to the user in association with a particular functionality for interacting with the system () controlled by the user interface in dependence on a rate of displacement of the body or body part of the user observed in the certain environment.

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.

The invention provides a lighting device comprising a housing. The housing comprises visible-light sources () arranged to generate visible light (), UV-lightsources () arranged to generate UV-light (), a light exit window () positioned to allow transmission of the visible light (), a photochromic layer () positioned upstream of the light exit window () and downstream of the visible light sources (), the photochromic layer () comprising at least one area with UV-photochromic material (), the UV-photochromic material () having a first color state and a second color state, and a control unit () connected to the UV-light sources () for controlling the UV-light sources (), wherein the UV-light sources are arranged to illuminate the photochromic layer (). The invention makes it possible to obtain dynamic light effects.
