Abstract
A lighting device includes a dimming module, a control module, a rectifier module and a light-emitting module. The control module is connected to the dimming module and saves a lookup table. The rectifier module is connected to the dimming module and control module. The rectifier module generates a rectified voltage to drive the dimming module and control module. The light-emitting module is connected to the dimming module and control module. The control module outputs an initial dimming signal to control the dimming module to output an initial drive signal so as to drive the light-emitting module. The control module detects the current operating voltage of the light-emitting module, and compares the current operating voltage with the lookup table to generate a target dimming signal corresponding thereto, such that the dimming module is controlled by the target dimming signal to generate a target driving signal to drive the light-emitting module.
