The invention relates to a modular LED-light comprising a first module () to which an input voltage (), preferably an AC-supply voltage, is guided, said first module comprising a second sub-module (B), preferably an insulating unit, a DC voltage separating the supply voltage by a galvanic separation being provided on the outlet of said insulating unit, and a control unit (G). Said LED light also comprises a second module (), preferably a light management module, comprising an additional sub-module (C) which is fed by the DC-initial voltage of the first module (), preferably a clocked constant flow source which is controlled by a control unit (E) of the second module (), and an LED-module (F) which comprises at least one LED path () and which is supplied by the additional sub-module (C).

Modular LED-lighting system

The invention relates to a method for controlling the operation of an LED luminaire () which has a plurality of LEDs () as light sources. The method has the following steps:

Operation of an LED luminaire having a variable spectrum

The invention relates to a modular LED lighting unit, comprising a first module () to which an AC supply voltage () can be supplied and which comprises: a second sub-module (B), at the output of which a DC supply voltage () is provided, which is galvanically isolated from the supply voltage, and a control unit (G), further comprising a second module (), preferably a lamp management module, which comprises a further sub-module (C) supplied with the DC supply voltage () of the first module (), preferably a constant current source, which is controlled by a control unit (E) of the second module (), an LED module (F) which has at least one LED range () and is supplied by the further sub-module (C), and an emergency light operating circuit which is connected to a rechargeable energy store (ES); and takes over powering the modular LED lighting unit in the event of failure of the AC supply voltage ().

Modular LED lighting having an emergency light function

The invention relates to a lighting arrangement with an operating device () and with an LED light source () which is controlled by said operating device and which is formed by at least two LEDs (), which emit light of different colors and together emit a white total light. The operating device () drives some of the LEDs () forming the LED light source () which are intended to emit monochromatic (non-white) light in such a way that said LEDs emit light signals representing certain operating parameters.

Optical signal output of operating parameters with an LED lighting unit

The invention relates to an operating device (BG) for lamps (LM), comprising an interface (IFi), by means of which the device (BG) may be provided with external dimming values. The device (BG) converts said provided external dimming values into internal dimming values on the basis of which the control of the connected lamps (LM) is achieved, the internal dimming values being of higher resolution than the external dimming values. According to the invention, the operating device (BG) is designed such that the conversion of the external dimming values into internal dimming values may be programmed. The operating device (BG) can particularly also be designed such that said conversion can be programmed with regard to the dynamics thereof. A programming can be provided by a time conversion relationship (linear, logarithmic or exponential time curve etc.) by means of which an internal dimming value corresponding to an external dimming value is reached.
