An adjustable lighting system for fluorescent lamp, which includes a lighting unit, a sensing apparatus and a control apparatus, is provided. The lighting unit can emit a light. 5 The sensing apparatus can sense if a target exists and generate a sensing signal accordingly. The sensing apparatus further generates and outputs a modulating signal based on the sensing signal. The control apparatus can receive the modulating signal from the sensing apparatus, 10 adjust a supporting current of a power source and support the pulse width and phase level of the supporting current to the lighting unit, to control the strength of the light emitted by the lighting unit. Particularly, if the target exists, the modulating signal drives the control apparatus to provide a 15 larger pulse width and phase level of the supporting current, so as to increase the strength of the light, or the modulating signal drives the control apparatus to provide a smaller pulse width and phase level of the supporting current, so as to decrease the strength of the light. |
