Abstract
The invention relates to a modular LED lighting unit, comprising a first module (1) to which an AC supply voltage (9) can be supplied and which comprises: a second sub-module (B), at the output of which a DC supply voltage (5) is provided which is galvanically isolated from the AC supply voltage (9), and a control unit (G), further comprising a second module (2) which comprises a further sub-module (C) supplied with the DC supply voltage (5) of the first module (1), in particular a pulsed constant current source, which is controlled by a control unit (E) of the second module (2), an LED module (F) which has at least one LED range (8) and is supplied by the further sub-module (C), inn particular a constant current source, 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 (9).
