Abstract
A self-adaptive illuminating device includes an illumination module and a driver module. The illumination module includes multiple electrically coupled illuminating units and a sampler. The sampler is electrically coupled to the illuminating units. The sampler tests at least one electrical property of the illuminating units by using a test signal for generating a feedback parameter. The driver module is electrically coupled to the illumination module. The driver module includes a signal processing unit and a power transformer. The signal processing unit is coupled to the sampler. The signal processing unit generates an operating parameter based on the feedback signal. The power transformer is electrically coupled to the signal processing unit and the illuminating units. The power transformer generates a resulting driving power based on the operating parameter and the initial driving power, and drives the illuminating units using the resulting driving power.
