摘要： The invention proposes an improved illumination system (1). The illumination system (1) comprises: an LED module (2) having at least one LED or OLED; at least one light sensor (3); and a control circuit (4) designed to control the current flowing through the LED module (2), and to be supplied with an individual sensing signal of each of the at least one light sensor (3). The at least one light sensor (3) is designed such that: the light sensor (3) has its sensitivity peak set to be at a lower wavelength than the spectrum emitted by the LED module (2), preferably below 420 nm, more preferably below 410 nm, and/or the light sensor (3) has its sensitivity peak set to be at a higher wavelength than the spectrum emitted by the LED module (2), preferably above 680 nm. Furthermore, the invention proposes a method for calibrating the illumination system (1). The control circuit (4) is designed to calculate a crosstalk calibration value, by detecting the contribution of a switching on or increasing of the current through the LED module (2) in a non-ambient light state, on the basis of the supplied detection signals.

摘要： A system (100) comprising a mobile communication terminal (1) and a buildings engineering system GT is disclosed. The mobile communication terminal has a display unit (4) and an input unit (3), preferably a combined input and display unit (4), a near-field communication interface (5) and a control unit SE. The control unit SE is set up to use the near-field communication interface (5) to read at least one parameter P of the buildings engineering system GT and to provide said parameter for software application 6 executed by the mobile communication terminal (1), wherein the software application is designed to take the at least open parameter P as a basis for depicting a user interface (9) on the display unit (2) and to evaluate a user input on the user interface (9) via the input unit (3) and to send actuation data based on the user input to the buildings engineering system GT. The mobile communication terminal (1) is preferably a smartphone or a tablet. The software application (6) can access a data memory (8) that is provided either in the mobile communication device (1) or in a manner functionally connected thereto. The software application (6) preferably accesses a further communication interface (10) of the mobile communication device (1) in order to transmit actuation data to the buildings engineering system GT. The actual communication between the mobile communication terminal (1) and the buildings engineering system GT is preferably not effected by means of near-field communication, since this is used preferably only to read the available parameters for operating the buildings engineering system GT, particularly a light installation.

摘要： The aim of the invention is to determine an operating point (220) of an AC/DC converter and optionally of a DC/DC converter, fed by the AC/DC converter, for feeding an operating DC voltage into a luminaire bus system in such a way that a power loss (202) of the luminaire bus system is reduced. This aim is achieved according to the invention in that a plurality of calibration DC voltages (282) are sequentially fed into the luminaire bus system, and a corresponding power consumption of the luminaire bus system is determined for each calibration DC voltage (282). The operating point can then be determined based on the power consumptions.

摘要： For the purpose of power factor correction, an inductance (21) is supplied with an input voltage (Vin), wherein a controllable switching means (24) that is coupled to the inductance (21) is actuated in order to selectively charge and discharge the inductance (21). A control device (14) for actuating the switching means (24) is designed such that it actuates the switching means (24) selectively on the basis of one of a plurality of modes of operation. In a first mode of operation, a switch-on time is stipulated for the switching means (24) on the basis of a minimum waiting time and on the basis of a voltage that drops across the switching means (24).
