    Abstract: Light sensors (1) are used in lighting applications, especially in combination with LEDs, to control and/or adapt the color point of light sources. Costs and/or performance of the light sensor (1) are essential in order to guarantee cost- effective light sources with reproducible color points. This aim is achieved by a light sensor (1) comprising a light diffuser (10), an optical non-transparent housing (11) having at least one window (12), at least one interference filter (13) and at least two photo sensors (14). The light diffuser (10) is arranged in such a way that light from outside the optical non-transparent housing (11) has to pass the light diffuser (10) so as to enter the interior of the optical non-transparent housing (11) via the window (12). The interference filter (13) and the at least two photo sensors (14) are arranged in the interior of the optical non-transparent housing (11), which interference filter (13) is arranged between the window (12) and the at least two photo sensors (14).

    Abstract: 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.
