Abstract:
1. An adjustable lighting system for fluorescent lamp, comprising: a light emitting unit, which is used to emit a light beam; a sensing apparatus, which is used to sense existence of a target object so as to generate a first sensing signal and sense an environmental brightness so as to generate a second sensing signal, and to generate a modulation signal based on the first sensing signal and the second sensing signal, wherein the sensing apparatus determines a range of the modulation signal based on the second sensing signal, and selects a specific modulation signal within the range based on the first sensing signal as the modulation signal, and sends out the modulation signal through a wired or radio frequency wireless way; and a control apparatus, which is connected to the light emitting unit and the sensing apparatus so as to receive the modulation signal from the sensing apparatus through the wired or radio frequency wireless way, wherein the control apparatus, based on the modulation signal, adjusts a pulse width and a phase level of current in a driving circuit is that is provided to the light emitting unit to control a light intensity emitted by the light emitting unit.
