LIGHTING DEVICE WITH USER INTERFACE FOR LIGHT CONTROL

摘要

The invention relates to a lighting device (1) comprising a lighting unit (2) and a user interface (3) for controlling the lighting colour and/or intensity of the lighting unit (2). The user interface (3) comprises a sensing device (5) with a large number of conductive elements (6), which responds to the proximity of a conductive object, like for instance a human finger pointing to the user interface (3). The user interface (3) can be based on proximity sensing or on touch-control. In both cases an element (6) on the outer surface (4) of the user interface (3) is selected, which corresponds to one of the selectable colours and/or intensities of the lighting unit (2). The selected element (6) generates an output signal which is sent to a processing unit (9), which converts this output signal into a driving signal suitable for the driver circuit (8) to drive the light sources (7). ® KIPO & WIPO 2007
