Abstract
The invention relates to an operating unit in which dimming information can be fed to a secondary side in respect of a galvanic isolator (4), wherein the operating unit (1) is improved in terms of cost. In particular, the dimming information is fed only to a first module (2) (a master module) either from outside by means of a sensor or from a primary side via the galvanic isolator (4) by means of a wireless channel (52). The first module (2) is further designed to relay the dimming information to at least one second module (3) (at least one slave module). The relaying of the dimming information can be effected either by a local bus (6), a wireless connection (9), a supply line, or via lines on a lamp module (12).
