Problems solved by technology

[0009] Although prior art dimmers and dimmer systems are adapted for multiple parallel physical channels or phase synchronous switching from dimmers, they still always require manual checking that the paralleling of dimmer channels is properly wired

Embodiment Construction

[0046] figure 1 A functional breakdown of a first example multi-channel dimmer D on the supply network N, L1 is shown. The multi-channel dimmer D has a plurality of dimmer channels K1 , K2 , Kx electrically isolated from one another, which each have a channel control device S1 , S2 , Sx. The dimmer channels K1 , K2 , Kx are connected in parallel on the output side to the load L via the connection terminals A1 , A2 , Ax, so that each can feed a part of the current to the load L.

[0047] Dimmer D is activated due to external command B. The master control device H generates control commands which reach the channel control device S1 of the dimmer channel K1 via the communication connection V.

[0048] The dimmer channel K1 contains a measuring device M1 which is suitable for generating information about the behavior of the electricity at a certain location in the channel, more precisely in particular about the zero crossing of the voltage. The dimmer channel K1 is therefore al...

Abstract

The invention relates to a method for detecting the correct routing of at least two electrically isolated dimmer channels connected in parallel of a dimmer, in particular a universal dimmer, and to acorrespondingly arranged dimmer, wherein, for each dimmer channel, information about a zero-crossing point in time of a sinusoidal AC voltage of a conductor connected thereto and information about a zero-crossing of a parallel adjacent channel are provided; and by measuring the phase shifts of the two voltages, it is determined whether there is a significant phase shift, wherein the identified phase shift represents an erroneous wiring.

Description

technical field [0001] The invention relates to a dimmer, ie a device for controlling the electrical power consumption of an electrical load, in particular an integrated or connectable lighting device. Dimmers are generally known and used to vary electrical power. The invention also relates to a method for identifying the correct wiring of at least two parallel-connected, electrically isolated dimmer channels of a dimmer. Background technique [0002] The power variation using the dimmer can preferably be achieved by leading edge phase control or by trailing edge phase control. In leading edge phase control, the current is switched on with a delay after the AC voltage zero crossing, and flows until the next current zero crossing. Leading edge phase control is preferred in case of inductive load response. Whereas in trailing edge phase control, the current is turned on immediately after the zero crossing and cut off again before the next zero crossing. Trailing edge phase...
