摘要:
A lighting system and a method for a operating a lighting system, enabling to obtain an identification tag (7) comprised in lighting design data (5) directly from an output beam (3), i.e. from the emitted light of the at least one lighting unit (2). It is thus possible to trace any unauthorized distribution of a lighting design by monitoring the emitted light without the need to directly access the controller or any other part of the lighting system.

A system comprising a device for placement in front of a display device, such as a TV screen, to change the optical properties of light received by a user observing said display device, when the display device is in an off state or standby state, while when the display device is in an on state, the device appears transparent.

The invention relates to composing a lighting atmosphere from an abstract description for example a lighting atmosphere specified in XML, wherein the lighting atmosphere is generated by several lighting devices, by automatically rendering the desired lighting atmosphere from the abstract description. The abstract description describes the type of light with certain lighting parameters desired at certain semantic locations at certain semantic times. This abstract atmosphere description is automatically transferred to a specific instance of a lighting system (14, 16, 18). The invention has the main advantage that it allows to create light scenes and lighting atmospheres at a high level of abstraction without requiring the definition of a lighting atmosphere or scene by setting the intensity, color, etc. for single lighting units or devices which can be very time consuming and cumbersome, particularly with large and complex lighting systems comprising many lighting devices.

The invention relates an electrical device for providing an output depending on an electrical input. The electrical device (1) is adapted to provide a constant output, if the electrical input is in a first electrical input range, and a dependent output, if the electrical input is in a second electrical input range, wherein the dependent output depends on the electrical input. The output can therefore remain constant, even if the electrical input, which is preferentially a DC grid voltage, fluctuates within the first electrical input range. Moreover, in the second electrical input range the output can be controlled by just controlling the electrical input like the DC grid voltage, without necessarily requiring an additional control construction of the electrical device. A resistance against fluctuations of the electrical input and a controllability of the output can therefore be realized in a relatively simple way.

An average power consumption of receiving units (3,5,7) for controlling apparatuses (4,6,8) in response to operation control signals from transmitting units (2) may be reduced by introducing devices (1,21) for controlling the power consumption of the receiving units (3,5,7) in response to detections of states of the apparatuses (4,6,8). The devices (1) may comprise controllers (30) for controlling the power consumption in a wireless, non-wireless, physical and/or logical manner. The devices (1) may comprise monitors (33) for monitoring power consumption, currents and/or voltages at the receiving units (3,5,7) and/or the apparatuses (4,6,8). The devices (1) may comprise receivers (40), detectors (41), converters (42) and transmitters (43) for receiving the operation control signals, detecting the states of the apparatuses (4,6,8), converting the operation control signals into converted signals, and transmitting the operation control signals or the converted signals to the receiving units (3,5,7) for controlling the power consumption of the receiving units (3,5,7) via the transmitted signals, wherein the transmitted signals correspond to power control signals.

The invention relates to an apparatus (1) for powering an electrical consumer (3, 4, 5) via a data connection (6, 7, 8). The apparatus comprises a power supply (2) for supplying power to the electrical consumer via the data connection, a data receiving unit (9) for receiving data to be sent to the electrical consumer, and a controller (10) for activating the supply of power to the electrical consumer via the data connection, if data to be sent to the electrical consumer have been received and the supply of power to the electrical consumer is deactivated. The electrical consumer itself does therefore not need to receive power from the apparatus, in order to stay alert to be able to react on data connection activity, thereby reducing the power consumption.
