| 摘要 |
The invention relates to an energy supply circuit (5) for a lighting module (4) for a motor-vehicle headlamp, wherein the lighting module (4) comprises a shunt resistor (Rsext) and at least one light source (D1, D2, Dn) that can be electrically supplied at least partially via the shunt resistor (Rsext), wherein the lighting module (4) also has at least three electrical connections (A1', A2', A3'), wherein a first connection (A1') and a second connection (A2') are provided for electrically contacting the shunt resistor (Rsext) and a third connection (A3') is provided for electrically contacting the at least one light source (D1, D2, Dn) connected downstream, wherein the electrical connections (A1', A2', A3') are designed as externally contactable connections, wherein the energy supply circuit (5) has a control unit (3) for outputting a supply current (Iv) controlled so as to be constant to the at least one light source (D1, D2, Dn) of the lighting module (4), wherein the control unit (3) has an auxiliary resistor (Rs), which is connected in parallel with the shunt resistor (Rsext). |
