Embodiment Construction
[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0016] The LED driving circuit provided by the embodiment of the present invention uses a control module to detect the negative pole voltage of the LED lamp, and compares the negative pole voltage of the LED lamp with a set threshold to determine whether the LED lamp is short-circuited. When the LED lamp is short-circuited, the output of the control module The terminal outputs a pulse control signal and controls the switch module to turn off, cut off the circuit of the LED lamp to realize short-circuit protection, and avoid the components from being burned out when the LED lamp is short-circuited. ...
