摘要: The invention relates to a power providing device (2) for providing power to a plurality of power receiving devices (31), a power distribution system including such power providing device (2), a method for providing power to a plurality of power receiving devices (31) and a corresponding computer program. During standby the power providing device (2) is beneficially supplied with power coming from a power source (1) dedicated or adjusted for the low energy consumption, e.g. a uplink port (23) or a shared power bus. The current drawn from such power source (1) (or the power provided to the downlink power receiving devices (31)) is measured and, for example, the derivative is used in order detecting a current increase just when it starts. This information may be used such the main power supply (29) gets started in order to be available for more power demand than available through the hierarchical powering coming from the standby power source (1).

摘要: The present invention relates to a powered device (331a, 331b, 531a) with two interfacing connections. The powered device (331a, 331b, 531a) comprises power switching units (350a, 350b, 550a1, 550a2) for forwarding the data signal as well the power received on the input to the output. Forwarding may be based on a detection of the powering state of the PD. In another embodiment, the Power-over-Ethernet input/output ports function bi-directionally, thereby allowing the user to daisy-chain devices in any direction. As power switching units, relays or solid-state power switches may be used.

摘要: The invention relates to a DC power distribution system, especially an EMerge DC power distribution system (1). The system is adapted such that power conductors (3, 4) electrically connected to different groups (5, 6) of ports (14) belong to separate power line communication (PLC) channels, wherein several electrical loads (7 . . . 10; 11 . . . 13) are in power line communication with a group of ports of a same PLC channel. The separation of the different PLC channels allows for a relatively simple determination to which group of ports which electrical loads are electrically connected. This information can be used by, for instance, a user to commission the electrical loads. For example, if the locations of the power conductors, which are electrically connected to certain groups of ports, are known, the information about which electrical loads are connected to which groups of ports can be used for determining the location of the respective electrical load.

摘要: The invention relates to a system (1) comprising a controlling device (4) like a sensor for controlling a controlled device (5) like a luminaire, a trigger unit (7) for generating a trigger signal, and an assigning unit (6) for assigning the controlling device and the controlled device to each other, if the trigger signal has been generated, wherein the controlling device controls the controlled device, if they have been assigned to each other. This allows an installer to generate assignments between the controlling device and the controlled device very easily. The installer just needs to connect the controlling and controlled devices, which should be assigned to each other, to the system and actuate the trigger unit. For instance, it can relatively easily be defined which luminaires should react on signals from which sensors.

摘要: The invention relates a system for controlling distribution of power to load elements via network connections (e.g. LAN). Low cost luminaires or other load elements can be powered via LAN connections (e.g. by power over Ethernet (PoE)) without featuring an Internet Protocol (IP) node. This is attractive because with such a system the installation cost down benefits of PoE can be applied also to installations that do not require advanced controls. This means that to switch them on or off, the power supply on the LAN port of the switch must be enabled or disabled. When load elements and load controllers (e.g. lighting controllers or light switches) are connected to the same switch, they are automatically paired to each other. This can be achieved through use of a network management protocol capability that some network switches have. This allows for easy installation and automatic intuitive commissioning.

摘要: The invention relates to a DC power distribution system for distributing DC power to one or several electrical devices. The system comprises an electrical device (2) for receiving DC power via an electrical conductor (4) from a power supply device (3) with a power supply control unit (5) and for transmitting a signal to the power supply control unit for requesting a lower power or a higher power. The power supply device is operable in a high power mode and in a low power mode, wherein the power supply control unit controls the power mode of the power supply device depending on the received signal. This allows adapting the power supply to the power, which is actually really needed in the DC power distribution system, in a technically relatively simple way. Particularly standby situations can be handled more efficiently.

摘要: The present invention relates to a load control system in which a power cable of a DC or AC is used for on/off control and dimming of connected load devices without adding significant hardware structure. The control is achieved through a change in the DC or AC bus voltage. A grid controller can perform on/off control and dimming for an entire group of connected load devices by changing the bus voltage. Connected load devices that do understand or want to make use of this feature will be unaffected. In order to reduce the effects of voltage drop, a calibration procedure is provided. The calibration procedure first triggers the connected load devices into a calibration mode and then initiates a number of predefined output level commands that allow the load devices to build an individual correction for the undesired voltage drop.

摘要: The invention relates to a lighting system (1) comprising a lighting device (3) for emitting light in a high-power mode and for providing a further function like a sensing function in a low-power mode and a switch (4) connecting the lighting device with a power supply (2). The switch is switchable between a high-power state, in which a higher power is provided to the lighting device via the switch, which allows the lighting device to emit the light in the high-power mode, and which may be regarded as being an ON state, and a low-power state, in which a lower power is provided to the lighting device via the switch, which allows the lighting device to provide the further function, and which may be regarded as being an OFF state. Thus, for instance, a sensing function can be provided, even if the switch is in its OFF state.

摘要: The invention relates to a DC power distribution system (1) comprising a power supply (50) for supplying DC power to an electrical device (11) like a luminaire, wherein the system includes a connection device (4) comprising a connection device contact (5) to which an electrical device contact (19) of the electrical device is to be connected, a load presence detection unit (7) for detecting whether the electrical device contact has been connected, and a power providing control unit (6) for providing the DC power of the DC power distribution system to the connection device contact, only if the load presence detection unit has detected that the electrical device contact of the electrical device has been connected to the connection device contact. Thus, a voltage is not applied to the connection device contact, if the electrical device is not connected, thereby reducing corrosion effects and the likelihood of installers getting electrified.
