Abstract: A lighting arrangement has a lighting module with a sensor element in parallel with a light source arrangement between module terminals. A measuring system is provided for measuring, at the module terminals, a signal which is dependent on the sensor element when the light source arrangement is turned off. Thus, sensing is integrated into or connected to a lighting module, such as LED module.

Abstract: The present invention relates to a simple data transmission protocol and a data receiving device (10, 10′, 10″, 10′″) for a power over Ethernet system (100′) using the simple data transmission protocol. The device (10, 10′, 10″, 10′″) comprises a port and a simple logic unit. The port is configured for receiving power and data transmitted to the device (10, 10′, 10″, 10′″) via an Ethernet connection (16′). The simple logic unit is configured to decode data encoded in a characteristic of one or more data packets received at the port. The data can be encoded in data packet length, data packet duration, number of data packets in a predetermined interval, and/or sequence of data packets. The simple data transmission protocol can reduce power consumption as in contrast to the Ethernet protocol MAC does not need to be decoded for information transfer. Hence only simple logic functions are required.

Abstract: Power management (203) for controlling a delivery of a DC-power to a device (204) operable in an accepting operational state or a non-accepting operational state with respect to receiving the DC-power comprises: receiving DC input power; providing an indication that the DC-power supply device (202) operates in a powered-device detection mode and not in an powered-device operation mode; connecting, when the DC-power supply device (202) is in the powered-device detection mode, the power to an energy storage unit (212); storing electrical energy currently received; determining, whether the power-acceptance criterion is fulfilled and, in case it is fulfilled, providing an instruction to operate in the accepting operational state; connecting the energy storage unit (212) and a power interface unit (206) when the external DC-power supply device (202) is currently operating in the powered-device operation mode. This reduces DC-power consumption of a DC-powered device (204) by reducing or eliminating its DC-power consumption while it is operating in the non-accepting operational state.

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.

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.
