Optoelectronic circuit and method for operating an optoelectronic circuit

A method for operating an optoelectronic circuit, the optoelectronic circuit comprising:

• at least one first light emitting diode;
• at least one second light emitting diode;
• a switch arrangement, which is connected between the at least one first light emitting diode and the at least one second light emitting diode in such a way and is configured in such a way that it switches over the at least one first light emitting diode and the at least one second light emitting diode between a series circuit formed by them and a parallel circuit formed by them, depending on a predefined ambient parameter;
• wherein the switch arrangement comprises a diode or a switch for connecting the at least one first light emitting diode in series with the at least one second light emitting diode;
• and
• a current matching circuit for matching the currents through the at least one first light emitting diode and the at least one second light emitting diode in the case of parallel connection, wherein the current matching circuit comprises a current mirror circuit comprising a first and a second current mirror transistor, wherein the first current mirror transistor is connected via its collector terminal to the at least one first light emitting diode and the second current mirror transistor is connected via its collector terminal to the at least one second light emitting diode;
• and wherein the switch arrangement is configured to form the series circuit comprising the at least one first light emitting diode and the at least one second light emitting diode whilst bypassing the current matching circuit in such a way that, in the case of series connection, the first current mirror transistor is switched in a high-resistance fashion and the second current mirror transistor is short-circuited;
• the method comprising:
• determining a predefined ambient parameter;
• and
• connecting the at least one first light emitting diode in parallel or in series with the at least one second light emitting diode depending on the predefined ambient parameter determined.
