If a PWM signal with the smallest permissible pulse width is given to the bus line, a signal high at the node Off, an undefined signal at the node Dimm, which results in the OFF state of the LE.
- a DC voltage signal that is, a PWM signal having a pulse width of 100% defined, produces a low signal, which is operated ⁇ by the LE in a predetermined dimming state at node dimming a high signal, ,
- FIG. 5 shows an example of a further operation state in which a PWM signal with egg ⁇ ner pulse width is set by 95% on the bus line, which leads to a further dimmed state, which can be arranged according to darker or brighter than the dimming status which results at a PWM pulse width of 100%.
- each master which is connected with its feeding or non-feeding terminal with egg ⁇ ner bus line, put all the connected LEs in the nominal operating state.
- the master which is integrally joined ⁇ with its feeding port on the bus, sets to at detected movement no clamping ⁇ lation (PWM signal of 0% duty cycle) to the bus.
- the master which is connected to the bus with its non-feeding connection, closes the bus lines briefly when movement is detected, whereby no voltage (PWM signal with 0% duty cycle) is present on the bus. This is possible because, as described above, the supply circuit of the feeding master is current limited.
- the master creates a PWM signal of the smallest allowable pulse width ⁇ on the bus, resulting in that all LEs, which are connected to this bus, generate no light (off state).
- the power of masters and slaves is minimized in this standby mode because the Ener gy ⁇ is minimal for the operation of the receiving devices on the slaves and the masters and the signal generation in the dining Master required.
- the master applies a PWM signal with a pulse width greater than the smallest permissible pulse width to the bus.
- This condition causes all LEs connected to this bus to produce light of a predefinable fixed value or to generate an amount of light proportional to the PWM signal pulse width (dimming condition).
- the motion detector may be provided with a time control, so that the corresponding control signal is applied over a bare vorgeb ⁇ time on the respective bus.
