The invention relates to a lighting system for at least one light-emitting means (), in particular for light-emitting diodes, comprising a light fixture (), in which the light-emitting means () and mechanical components like a housing, cooling element, reflector, etc. are located; comprising a convertor () for operating the light-emitting means (); comprising an operating unit () having a charge storage (), like a smart phone, for example, for changing a mode of operation of the lighting system (), wherein in a first mode of operation, light is emitted across a first light exit surface by the lighting system (), and in a second mode of operation, light is emitted across a second light exit surface, wherein the first light exit surface and the second light exit surface have different light emission characteristics.

Lighting system for changing the emission characteristics operating in at least a first mode and a second mode and comprising LEDS, a converter, and an operating unit

The invention relates to a building equipment-based communication system () comprising at least one building equipment-based device as a master unit (), in particular a light fixture, to which at least one slave unit (), in particular a sensor and/or actuator, can be connected via a network, preferably in a wireless manner; the slave unit () is designed to communicate with the master unit () via the network connection either directly or indirectly by way of other slave units (); and the master unit () is designed to send, via a communication interface (), information received from the at least one slave unit ().

Building equipment-based communication system

The invention relates to a drive circuit for operating an illuminant, preferably at least one LED, comprising an isolated converter which is clocked on the primary side by a control unit by means of at least one controlled switch unit, said converter supplying a rectifier starting from which the illuminant can be fed, a measurement circuit for indirectly measuring the current on the secondary side of the converter having a transformer with at least one winding on the primary side.

Isolated active circuit for measuring the current of an illuminant on the secondary side

The invention relates to a method for transmitting information from an operating device (K) for lamps (L), in particular a converter for LEDs, to a control unit (ST) connected to the operating device (K) via voltage supply lines () thereof, having the following steps: the control unit (ST) preferably periodically temporarily interrupts an AC supply voltage (Vin) of the operating device (K), and the operating device (K) applies a voltage signal (V) to the voltage supply lines () during the interruption of the AC supply voltage (Vin) which is evaluated by the control units (ST) as information.
