The invention discloses an LED dimming control system. A source side control module in the LED dimming control system is electrically connected to a secondary side control module through a first isolation module, and the secondary side control module is connected to an external interface control module through a second isolation module. Electrical connection; the source side control module transmits the first power supply abnormality signal to the secondary side control module when detecting the power supply signal abnormality; the secondary side control module transmits the second power supply abnormality signal to the external interface control through the second isolation module according to the first power supply abnormality signal The module transmits the abnormal dimming signal to the external interface control module when the abnormal dimming signal is detected; the external interface control module adjusts the abnormal power supply adjustment signal and the abnormal dimming adjustment signal output to the host computer. Through the technical solution of the invention, the three parties of the source-side control module, the secondary-side control module and the external interface control module are effectively isolated, and the working safety of the LED dimming control system is improved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of LEDs, in particular to an LED dimming control system. Background technique [0002] LED (Light Emitting Diode, LED for short) is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light, and has the advantages of easy control, low-voltage DC drive, and long service life. At present, LEDs are widely used in various occasions, such as lighting, display backlighting, and displaying. [0003] In the traditional LED dimming control scheme, all the signals between the dimming terminal and the load signal output terminal adopt the signal transmission mode of direct transmission, which makes the transmission process of the various signals in the LED dimming control system greatly disturbed. The working safety of the LED dimming control system is reduced. Contents of the invention [0004] In view of this, the...
