| 摘要 |
The invention relates to a method and operating circuit (11) for operating an electric luminous element (12), wherein the luminous element (12) is supplied with electrical operating energy by a DC voltage source (1) by means of an interconnected converter (10), wherein the current (I) received by the converter (10) is measured and compared to an upper limit value (IG), wherein the DC voltage source (1) is disconnected or cut off from the converter (10) if the current (I) received by the converter (10) exceeds the upper limit value (IG), and wherein the disconnecting/cut-off switching mechanism (2) is deactivated during a switch-on phase. |
