| 摘要 |
An illumination system (200), comprising a switch (210), an LED light source (230), a current control circuit (220), electrically connected between the switch and the LED light source, when the switch is turned on, the current control circuit outputs a driving current to change the brightness of the LED light source from a first brightness (L1) to a second brightness (L2), and during the change of the brightness of the LED light source from the first brightness to the second brightness, the switch is flashed to stop the change of the brightness, so that the brightness of the LED light source is maintained at a third brightness (L3) between the first brightness and the second brightness. "Flashing" is as defined in the specification. |
