An illumination adjusting device for receiving power from a power supply and supplying output voltage to a lighting unit is provided herein. The illumination adjusting device includes a detector for detecting ambient illumination intensity and generating an ambient illumination value according to the ambient illumination intensity; a comparator for comparing the ambient illumination value with a predetermined value, the comparator outputting a first power signal when the ambient illumination value is lower than a predetermined value; an adjustor for adjusting the output voltage according to the first power signal, as a result, light emitted by the lighting unit is controlled within a predetermined illumination intensity range. A related illumination adjusting method is also provided.
An illumination adjusting device for receiving power from a power supply and supplying output voltage to a lighting unit, comprising:
The illumination adjusting device as described in claim 9, wherein the adjustor comprises a first input port connected to the first fixed contact, a second input port connected to the second fixed contact, a third input port connected to the third fixed contact, a output port connected to the lighting unit, a ground port grounded, and a control port connected to the controller.
