摘要： The present invention relates to a device and method for controlling the color point of an LED light source (50). Color point control is a most interesting product feature both for white and colored LED light sources. In known methods for the color control of RGB LED light sources use is made of flux and color sensors. However, there are difficulties with respect to sensing quickly changing ambient light, deeply dimmed colors, coordinating the measurements with the switching of the LEDs, and controlling the color in LED light units comprising a number of independent LED lamps, e.g. segmented wall washers and LCD backlights. It is proposed according to the present invention to control the color of the LED light source (50), using a model-based feed forward approach. Factors relating the parameters controlling the LED currents to the brightness for the different colors (and segments) are stored and used for open loop control. A slow-running procedure continuously measures and updates these factors. Whilst the measurements are e.g. synchronized with the PWM, the procedure itself can run considerably slower and updates the factors asynchronously.

摘要： In an arrangement of lighting devices (10), a remote control device (30) and a central control device (20), a particular lighting device to be controlled by means of the remote control device may be selected by a user transmitting a selecting command (42, 43). When the central control device receives the selecting command (44), it carries out a selection sequence (45) during which it controls the lighting devices in one or the other sequence so as to have their output change temporarily (45, 46, 47). If the remote control device, which is directed to the particular lighting device (41), senses such an output change (50), it transmits data representing such an event (51) to the central control device. When the central control device receives such event data (52), it determines the particular lighting device as that to which the remote control device is directed (53) for subsequent control (54) of this particular lighting device.
