Abstract
An illuminance calibration device includes a processing module and a light detecting module. The processing module executes an illuminance calibration process. The light detecting module detects the current illuminance of a target position and transmits the current illuminance to the processing module. When the processing module is executing the illuminance calibration process, the processing module transmits a test signal to a lighting device to adjust the brightness of the lighting device by the minimal brightness adjusting unit of the lighting device so as to obtain the adjusted current illuminance of the target position. Then, the processing module generates a brightness adjusting signal according to the current illuminance, the adjusted current illuminance, the minimal brightness adjusting unit and a target illuminance in order to adjust the brightness of the lighting device, such that the illuminance of the target position reaches the target illuminance.
