Abstract: The invention relates to a lighting system (1) comprising a lighting device (6) having a first USB-PD connector and a power providing unit, which is preferentially a component of a power providing device (4) and which is operable in different operational modes. A second USB-PD connector is electrically connected with the power providing unit and adapted to be connected with the first USB-PD connector for generating a USB-PD connection (5) via which power and optionally also data are receivable by the lighting device. A connection feature value being indicative of a feature of the connection is determined and the operational mode of the power providing unit is controlled depending on the determined connection feature value. This allows for a reaction on the current connection situation. For instance, if the connection feature value indicates a relatively low thermal coupling, the power providing unit may provide less power.

Abstract: The invention describes an LED lighting module (1) comprising input terminals (13hi, 13lo) for connecting to an input voltage (Uin); an LED load (10) realised to operate at an upper threshold voltage level (Vdim); and a regulation circuit (11, 12) realised to decrease LED current (ILED) through the LED load (10) when the input voltage (Uin) is greater than the upper threshold voltage level (Vdim). The invention further describes an LED lighting arrangement (4) and a method of driving an LED load (10).

Abstract: The invention describes an LED lighting arrangement (1) comprising an LED load (10) comprising a number of LEDs (100); input terminals (14hi, 141o) for connection to a power supply (2) realised to provide an input voltage (UPS) at a primary input voltage level (VPS); a voltage boost module (11) realised to boost the input voltage (UPS) to a level above the primary input voltage level (VPS) on the basis of a dim level input signal (30); and a dimming module (12) realised to decrease the LED current (ILED) through the LED load (10) when the boosted voltage (Uboost) exceeds the primary input voltage level (VPS). The invention further describes a method of driving an LED lighting arrangement (1).

Abstract: A power scavenger circuit (180) in a sensor device (100) for a lighting system (1) comprises: a controllable boost converter (110) having an input (111, 112) for receiving an input current (Iin) from an interface (2), and having an output (119a, 119b) for providing an output voltage (VB); a capacitor (130) coupled to the output of the boost converter (110); a second converter (140) having an input (141, 142) coupled to the capacitor and having an output (149a, 149b) for providing a supply voltage (VDD) for a microprocessor (150). A scavenging control device (120) has a sensing input (121) coupled to said converter input for sensing the voltage (Vout) at said converter input. The scavenging control device controls the boost converter in such manner that the sensed voltage is kept constant, so that the voltage at said interface can be considered as an output signal from the sensor device.

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.
