| 摘要 |
The present invention relates to an arrangement for emitting mixed light comprising at least three diodes, comprising a first drive circuit supplying the first diode with current via a first channel, wherein the first diode is of type A, wherein type A represents a diode configured to emit green and/or green-white light, wherein the drive circuit supplies the series-connected second and third diodes with current via a second channel, wherein the second diode is of type B, wherein type B represents a diode configured to emit red light, wherein the third diode is of type C, wherein type C represents a diode configured to emit blue and/or blue-white light, wherein the drive circuit is configured to change, depending on an operating parameter of at least one diode, the current supply for the first and/or second channel so as to counteract a colour locus shift of a diode. |
