Actuation of a lighting module |
| 摘要 |
A circuit for actuating a lighting module, comprising at least two semiconductor light-emitting elements (D1, D2) which are connected in series in a first operating mode; wherein, in the event of a predetermined threshold value for an operating voltage (101) being undershot, a second operating mode is detectable (102); and wherein, in the second operating mode, the at least two semiconductor light-emitting elements (D1, D2) are alternately actuable. |

1. A circuit for actuating a lighting module, comprising at least two semiconductor light-emitting elements, the circuit being configured so that said at least two semiconductor light-emitting elements are connected in series in a first operating mode and
wherein, in the event of a predetermined threshold value for an operating voltage being undershot, a second operating mode is detected; wherein, in the second operating mode, the at least two semiconductor light-emitting elements are alternately actuated at a frequency in a range of between 65 Hz and 100 KHz so that no flicker can be perceived by the human eye. |
