METHODS FOR DRIVING AN LED LIGHTING DEVICE AND CIRCUITS THEREOF |
| 摘要 |
A method for driving an LED lighting device includes receiving an input voltage from a battery unit and converting the input voltage into a driving current to drive the LED lighting device. The method further includes detecting whether the battery unit is in a low battery state. When the low battery state of the battery unit is detected, the driving current is reduced. |

1. A method for driving an LED lighting device, comprising:
receiving an input voltage from a battery unit; converting the input voltage into a driving current to drive the LED lighting device; detecting whether the battery unit is in a low battery state; and reducing the driving current when the low battery state of the battery unit is detected, wherein the driving current is reduced in a plurality of steps, and the driving current is reduced by a preset value during each of the plurality of steps. |
