Abstract: Each of multiple components, including a first lamp, is operable in a first mode in which it appears to a commissioning tool as awaiting commissioning, and a second mode in which it does not appear as such to the commissioning tool. Each component begins a commissioning process in the first mode. The first lamp then triggers a second one or more of the components (e.g. other lamps) to switch to the second mode, so that during commissioning the second components will not to appear to the commissioning tool as awaiting commissioning. Following this, the first lamp operates in the first mode so that it appears to the commissioning tool as awaiting commissioning (thereby representing the first and second lamps jointly). The first lamp also interacts with the commissioning tool on behalf of the second components, in order for the first lamp and second components to be commissioned as a group.

Abstract: Devices (1) for driving light sources (5) comprise drivers (2) operable in different modes and controllers (3) for, in response to detections of values of input voltages supplied to the devices (1), bringing the drivers (2) in one of the different modes. Such devices (1) can be used solely and in series and parallel combinations. In case the value of the input voltage is smaller/larger than a threshold value, a first/second mode is selected. The first mode is a preset-mode, the second mode is a feedback-mode. A combination of the light source (5) and the driver (2) may show a constant-resistor-load-behavior in the preset-mode. The device (2) may comprise a switch (25) that in the preset-mode is operated at a constant conducting time and that in the feedback-mode is operated in response to feedback-information derived from the light source (5). At start-up, the driver (2) may be kept deactivated during a time-interval.

Abstract: A tubular solid state lighting device has a pin safety circuit electrically connected to connection pins of the one end. The pin safety circuit comprises two protection components, of different types. In one set of examples, there is an electrically controlled isolation switch and an electronic switch which functions as a high voltage isolation barrier. The switch provides full galvanic contact separation, whereas the isolation barrier provides current protection if the isolation switch is not functional. In another set of examples, there is a mechanically controlled isolation switch and an electrical or electronic isolation barrier. This provides two levels of protection, but requiring only a single manual operation by the installer of the lighting device. It avoids end-of-life protection circuitry being triggered during the installation of the lighting device.

Abstract: Light sources for replacing fluorescent lamps comprise light circuits with light emitting diodes, first and second terminals located at first and second ends of the light sources for exchanging first signals with high-frequency ballasts, and converter circuits for converting the first signals into second signals for feeding the light circuits. The converter circuits comprise reactive circuits for matching the light circuits and the high-frequency ballasts and provide safety to persons when installing the light sources. The light sources may further comprise protection circuits for protecting parts of the light sources against problems. The protection circuits may comprise monitor circuits for monitoring parameters of the light sources and for in response to monitoring results short-circuiting outputs of the converter circuits, and fuses. The reactive circuits may comprise protecting capacitors.

Abstract: A system comprises a plurality of components connected in a wireless network and at least one unconnected (new) component available to join the network. The components are divided amongst a plurality of luminaires, each comprising a respective subgroup of the components including at least one lamp, and each subgroup has a respective subgroup ID. At least a first one of these components is configured to automatically detect whether a previously-present one of the components from the same respective subgroup as the first component is missing from the network. In response to detecting that the previously-present component is missing, the first component automatically causes the new component to be joined to the wireless network, and to be assigned to the same subgroup as the first component under the same subgroup ID.
