    摘要： A method of displaying a visual representation of a luminaire comprises obtaining a three-dimensional model of the luminaire and one or more texture maps associated with the three-dimensional model, determining a camera location and orientation based on user input, and determining observation angles on each of a plurality of surface positions of the three-dimensional model based on the camera location and orientation. The visual representation includes a representation of a light effect generated by one or more activated light sources in or on the luminaire, the one or more light sources and the luminaire are rotatably symmetric with respect to a central axis of the luminaire, and the surface of the luminaire comprises a plurality of repeating sections. The method further comprises determining, for each of the plurality of surface positions, an applicable light value for a respective surface position based on the observation angle determined for the surface position and a light value predetermined either for the surface position or for a corresponding surface position of a different section of the luminaire, and rendering the visual representation of the luminaire based on the three-dimensional model, the one or more texture maps, the applicable light values, and the camera location and orientation. At least some of the applicable light values are determined based on light values predetermined for corresponding surface positions of a different section of the luminaire.

    摘要： A controller (1) for performing presence detection with a first sensor system (41,42) and a second sensor system (31-37) is configured to receive sensor signals from the first sensor system and/or the second sensor system. The second sensor system is of a different type than the first sensor system. The controller is further configured to determine which first one or more areas of the plurality of areas are in both the sensor range of the first sensor system and the sensor range of the second sensor system based on the sensor signals and control the second sensor system to perform, with respect to the first one or more areas, a second task other than a first task to be performed by the first sensor system. The first task comprises obtaining sensor data to be used for presence detection in the first one or more areas.

    摘要： A switch mode power converter input terminals to receive high voltage input power and output terminals to provide output power. The converter has a high side/float main power switch, a current sensing resistor and an energy storage component. A current setting circuit is used to control a current source circuit to drive a through a biasing resistor connected between the high voltage input and a reference voltage potential according to a grounded current setting. The high side power switch is controlled by a high side/float control circuit based on sensing a voltage across a series connection of the current sensing resistor and the biasing resistor. Thus the grounded current setting is transmitted to the high side control circuit without using complex level shifter circuit such as transformer or opto-coupler.
