FLICKER MEASURING APPRATUS AND FLICKER MEASURING METHOD THEREOF

摘要

PURPOSE: An apparatus and method for measuring a flicker are provided to accurately determine the status of a power supply unit by measuring the flicker of a light emitting device. CONSTITUTION: A flicker measuring apparatus(100) includes a power supply unit(110), a light source(120), a signal processing module(140), and a control module(150). A light detecting module detects light emitted from one or more light sources. The power supply unit provides a dimming signal to the light source. The signal processing module converts the detected light into an electric signal and processes the signal. The control module controls the power supply unit based on the dimming control signal and measures a flicker of the light source by using the electric signal which is processed. The control module determines the status of the power supply unit according to a flicker measurement result.
