LIGHT EMITTING DIODE DRIVER CIRCUIT AND METHOD FOR LIGHT EMITTING DIODE DRIVING |
| 摘要 |
A light emitting diode driving circuit including a first LED array; a second LED array; an LED driving circuit configured to provide a constant current to the first LED array and/or the second LED array; a linear circuit configured to selectively provide a second current that is smaller than the constant current to the second LED array; and a driving controller configured to control the LED driving circuit and the linear circuit such that the constant current is selectively provided to the first LED array or the second LED array based on an operating mode, and such that the second current is provided to the second LED array only when the constant current is being provided to the first LED array. |

1. A light emitting diode driving circuit comprising:
a first light emitting diode (LED) array; a second LED array; an LED driving circuit configured to provide a constant current to at least one of the first LED array and the second LED array; a linear circuit configured to selectively provide a second current that is smaller than the constant current to the second LED array; and a driving controller configured to control the LED driving circuit and the linear circuit such that the constant current is selectively provided to one of the first LED array and the second LED array based on an operating mode, and in response to the constant current being provided to the first LED array, the second current is provided to the second LED array. |
