A control/regulating system is provided for controlling/regulating an LED field with n LEDs, where n&#x3e;2, with outputs at which control/regulating signals for controlling/regulating controllable switching elements can be tapped. Activation/deactivation times of impulses can be defined by the control/regulating system through the control signals/regulating signals. One and/or several controllable switching elements can be actuated during the determined impulses for closing or opening. A number of k groups can be specified. Each LED is allocated to one of the k groups such that each of the k groups mcontains LEDs, where 1&#x2264;j&#x2264;k and &#x3a3;m=n apply, a reference time &#x3b1;=&#x3b1;. . . &#x3b1;can be determined for each group and the activation and deactivation time of the impulse for each LED of every group can be determined as a factor of the reference time &#x3b1;=&#x3b1;. . . &#x3b1;, where 1&#x2264;p&#x2264;mapplies.

Control and/or regulating system, circuit arrangement and procedure for reducing the maximum current in an LED (light-emitting diode) field

A circuit arrangement for operating a plurality of lighting devices having: a first control component, which is connected to a first lighting device or is formed integrally with a first lighting device; at least one second control component, which is connected to a second lighting device or is formed integrally with a second lighting device; at least one main control device, which is connected to the first and to the second control component and is configured to supply the control components with an operating voltage; and at least one data communications line, which is connected to the two control components and to the main control device. The main control device is is able to transmit a first position coding signal for the position coding of the first control component and at least one second position coding signal for the position coding of the second control component.
