The invention discloses a panel lamp circuit and a control method thereof. The panel lamp circuit comprises a brightness detection module, a control module, a main lighting module and an auxiliary lighting module. The brightness detection module is electrically connected with the control module, and the brightness detection module is used for generating a detection signal according to the ambient brightness. A first output end of the control module is electrically connected with a first end of the main lighting module, and the control module is used for controlling the conducting state of the main lighting module according to the relation between the detection signal and a set voltage threshold. A second output end of the control module is electrically connected with a first end of the auxiliary lighting module, and the control module is used for generating a pulse width signal according to the size of the detection signal so as to adjust the brightness of the auxiliary lighting module. According to the embodiment of the invention, automatic control over the main lighting module and the auxiliary lighting module and brightness adjustment of the auxiliary lighting module can be realized, and meanwhile, independent control over the main lighting module and the auxiliary lighting module can be realized, and the conduction states of the main lighting module and the auxiliary lighting module do not influence each other.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of LED lighting, and in particular to a panel light circuit and a control method thereof. Background technique [0002] Panel light is a traditional indoor lighting fixture, which is mainly used for basic lighting in indoor office spaces.
