  • Publication number: 20200119768
    Abstract: The invention relates to a cable (12) and a male connector (10, 20) attachable to the cable (12) for transmission of power and data for use in power focused applications, in particular lighting applications. The male connector (10, 20) comprises a contact for power transmission (P), a contact for data communication (D) and optionally a contact for configuration signaling (C), wherein a conversion circuit (11, 21) is configured to translate the configuration signaling (C) to be transmitted via a single twisted pair of signaling wire together with the power transmission (P), and/or the data communication (D). Providing conversion circuitry within the connector allows to combine two or more signals received via respective connectors of the male connector and generate a combined signal to be transmitted over a single pair of twisted signal wire, the connector allows the usage of a cable with much higher flexibility.

  • Patent number: 10530590
    Abstract: A method, computer program product and device for generating a power signal are provided. In a power distribution system (e.g. PoE), a device (2) (e.g. PD) comprising at least one capacitor (e.g. bulk capacitor) parallel to a load (26) of the device, is powered by a power supply (1) (e.g. PSE). The power supply (1) is arranged for powering the device (2) when at least a minimum current (e.g. MPS) is drawn by the device (2) from the power supply (1). The device (2) determines, by measuring the voltage over the at least one capacitor, whether the current is drawn (partially) from the at least one capacitor. In which case the device (2) is controlled to draw current such that at least a minimum current is drawn from the power supply (1) and the power supply (1) remains powering the device (2).

  • Patent number: 10420191
    Abstract: The invention relates to a control system (4) for controlling lighting units (30, 31, 32, 33) of a lighting system (1), wherein the lighting units are assigned to different areas and the control system is adapted to control the lighting units in accordance with a lighting command, which defines desired power levels, and depending on occupancy information, which is indicative of a degree of occupancy of the areas, such that different lighting units are set to their desired power levels at different times, even if the provided lighting command requests to set the lighting units to their respective desired power levels at substantially the same time. This can reduce the likelihood of, for instance, blown fuses or damaged components of the lighting system, while, because of the consideration of the occupancy information, the delay in setting the lighting units to their desired power levels may be not or only hardly visible.

  • Patent number: 10405405
    Abstract: The present invention proposes to use a power negotiation connection (e.g. the VBUS channel) of a power delivery interface for transmitting or receiving control commands or, respectively, status information to/from a lighting device. The power negotiation connection can be used as a communication channel that is fully independent of the data connection. It uses, for example, different protocols and different wires than the data connection. Control commands, such as dim level or color, can be encoded in a vendor defined message of a related power negotiation protocol.

  • Patent number: 10341124
    Abstract: The invention relates to a power distribution system comprising a power providing device (3) for providing power and a powered device (4, 5, 6) like a luminaire to be powered by the power providing device. The power providing device and the powered device are operable in a maximum power mode and a normal operation mode, wherein in the maximum power mode the powered device consumes an amount of power maximally consumable by the powered device and the power providing device measures the power consumed by the powered device. This measured power allows for an allocation of an amount of power in the operational mode, which is really maximally needed, wherein it is not necessary to allocate a larger amount of power, which is large enough to consider, for instance, a maximally assumed length of an electrical connection (8) connecting the devices, thereby improving the power budget allocation.
