Abstract:
A light adjusting device for a light emitting diode includes a switch, a detecting unit and an illumination adjusting unit. The switch is coupled to a power terminal, which is utilized for providing power for the light emitting diode. The detecting unit is coupled to the switch, and is utilized for determining a status of the switch, so as to generate a detecting result. The illumination adjusting unit is coupled to the detecting unit, and is utilized for adjusting illumination of the light emitting diode according to the detecting result.
