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.

Abstract: The invention relates to a lighting system (10), a method of controlling the lighting system and a computer program product. The lighting system comprises a light source (30), a controller (100) for controlling the light source (30), and a light sensor (20). The light source is configured for altering a spectrum of the light emitted by the light source. The light sensor is arranged for sensing spectral information comprising at least two different portions of a spectrum of light impinging on the light sensor. The controller is configured for receiving a sense signal (SS) and for generating a drive signal (DS) supplied to the light source to determine the spectrum of the light emitted by the light source in dependence on the spectral information from the light sensor. The effect of the measures according to the invention is that the sensing of the spectral information of the light impinging on the light sensor enables the controller to adapt the color temperature of the light emitted by the light source such that the perceived color temperature more closely corresponds to the intended color temperature.

Abstract: An illumination assembly comprising a light source, an optical component and a positioning mechanism comprising a movable member and at least one electromechanical polymer actuator, being operable to move either the optical component or the light source or both to different positions along a mechanical axis, is configured and can be conveniently adjusted to project a light beam at a distant location with a variable beam spread and over a variable distance. The capability of an electromechanical polymer actuator to realize large deformations allows for ample displacement of the positioning mechanism. Thus, the illumination assembly according to the invention is highly suited for fine-tuned actuation of a light beam, particularly from spot to flood illumination. These features further provide for a mechanically simple device that is both inexpensive and reliable.
