Abstract: A system (1) is configured to control first and second pixelated lighting devices (10,20) based on a dynamic light scene. The dynamic light scene comprises light settings that move across individually controllable light segments (12-18,22-27) of the pixelated lighting devices over time. An initial mapping has been determined from the dynamic light scene to the light segments of the first lighting device. The system is 5configured to obtain a position of the first lighting device relative to the second lighting device, determine a spatial offset for the initial mapping based on this position, determine a spatial direction of the dynamic light scene relative to the first lighting device based on this position, and control the first lighting device to render the dynamic light scene according to an adjusted initial mapping. The initial mapping is adjusted by offsetting the initial mapping 10according to the spatial offset and the spatial direction.

Abstract: A lighting device comprising a lighting unit comprising a plurality of lighting modules and a termination module, wherein the termination module is configured to have an electrical characteristic different from that of each lighting module, such that it draws a different amount of current in response to an applied drive voltage. The present invention suggests automatically determining a lighting module count of the lighting unit upon detection of the termination module, by measuring a change of a current passing through the lighting unit while sequentially activating the modules of the lighting unit.

Abstract: A method comprises receiving (222,224,226,232,234,236) information identifying power on/off-related behavior (e.g. shutdown moment and/or elapsed time) from each of the plurality of lighting devices and partitioning the plurality of lighting devices in groups of lighting devices, e.g. Group1: L1+L2 and Group2: L3, based on the received information. Each of the groups comprises only lighting devices with similar power on/off-related behavior. The method further comprises controlling (242) the lighting device in response to a user command, determining that a problem has occurred when controlling the lighting device, and identifying the group that comprises the lighting device. The method also comprises determining a power on/off state of at least one other lighting device in the identified group, determining diagnostic information based the determined power on/off states, and providing (243) the diagnostic information to the user. The diagnostic information indicates a likely cause for the problem.

Abstract: A monitor device is provided for monitoring a lighting arrangement of lighting elements of unknown electrical load, and a driver using the monitoring arrangement. A set of duty cycles is applied to switches which control sub-sets of lighting elements thereby to create a desired light output. With this desired duty cycle setting, the current for an individual duty cycle period is monitored, in particular to detect variations in a current plateau level within the individual duty cycle period. This is used to determine electrical characteristics or parameters including at least a cable resistance between a power supply unit and the lighting arrangement. A power consumption of the lighting arrangement may then be obtained. This avoids the need to probe the sub-sets of lighting elements individually in order to determine the nature of the load and its power consumption.
