| 摘要 |
<p>The invention concerns a light-emitting diode device (10) comprising at least two branches mounted electrically in parallel and each comprising a light-emitting diode, including a first branch (11) comprising a first light-emitting diode (LED1) and a second branch (12) comprising a second light-emitting diode (LED2), and a first detection means (DET1) designed to detect a failure of said first light-emitting diode. According to the invention, the light-emitting diode device further comprises a current regulator (REG1) mounted to electrically bypass said first light-emitting diode, and a switching circuit (COM1) controlled by said detection means to alternately block the current passing through said first light-emitting diode or said current regulator, depending respectively on whether or not said detection means detects a failure of said first light-emitting diode.</p> |
