摘要:
A method for operating a circuit configuration which includes a power source, a light diode field switched serially with the power source in which the light diode field comprises at least two serial circuits including at least one light diode and a switch, a control and/or regulating means for the light diode field, and a voltage sensor. The control and/or regulation means controlling the controllable switches and the power source such that the control and/or regulation means addresses the controllable switch of at least one serial circuit of the light diode field during a clock cycle for a pulse duration determined by the control and/or regulation means using a control pulse at the control input of the controllable switch for closing. The control and/or regulation means addresses the power source shortly before or at the latest simultaneous with the end of a pulse duration such that the current is reduced, namely by the amount of current through the serial circuit. The controllable switch at the end of the pulse duration is addressed by the control and/or regulation means for opening. During subsequent clock cycles the control and/or regulation means switch on only one of the controllable switches of the serial circuits for a period identified as diagnostics period.

A light module for an exterior light, comprises a circuit board holder, at least one circuit board disposed in the circuit board holder comprising a plurality of LEDs and a cover which covers the circuit board holder and the circuit board disposed therein. Embodiments of the cover comprise a transparent cover which is permeable to light in order to transmit light produced by the LEDs. An optical system for influencing the beam path through the transparent cover may be disposed on the inner side of the transparent cover for each LED. Each optical system can comprise a central optical element, which is disposed directly above the LED, two outer optical regions on the opposite sides of the central optical element, a second optical element which laterally encloses the central optical element and the two outer optical regions and has at least one longitudinal side and a third optical element which extends linearly outside the second optical element parallel to a longitudinal side.
