    • 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.

    • The invention provides a method for measuring a flux of a selected individual lightsource among a plurality of lightsources, wherein each lightsource is controlled by an associated pulse width modulated signal, and each pulse width modulated signal has a first logic level interval at a first extremity of a timecycle wherein the associated lightsource is to be lit, and a second level interval during the remainder of said timecycle. The method according to the present invention comprises time inverting the pulse width modulated signal of all lightsources that have a first logic level interval at the same extremity as the first logic level interval as the individual lightsource to be measured (usually this applies for the pulse width modulated signals for all lightsources), by shifting their high level interval to a second extremity of a timecycle and measuring the flux of the selected individual lightsource at the first extremity of the timecycle.

    • 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.
    • 本发明涉及一种用于控制LED光源(50)的色点的装置和方法。 色点控制是白色和彩色LED光源的最有趣的产品功能。 在已知的用于RGB LED光源的颜色控制的方法中,使用通量和颜色传感器。 然而,在感测快速变化的环境光,深色调颜色,通过LED的切换协调测量以及控制包括多个独立的LED灯的LED光单元中的颜色方面存在困难,例如, 分段洗墙机和LCD背光源。 根据本发明提出了使用基于模型的前馈方法来控制LED光源(50)的颜色。 将控制LED电流的参数与不同颜色(和段)的亮度相关联的因素存储并用于开环控制。 一个缓慢运行的程序不断地测量和更新这些因素。 虽然测量是例如 与PWM同步,程序本身可以运行相当慢,并且异步更新这些因素。
