Summary:An LED driving detection analog circuit is characterized by comprising a PWM frequency conversion driving module, an LED driving circuit, an AD detection module, an LED detection circuit, LED lamp beads and a working loop of the LED lamp beads. The PWM frequency conversion driving module is connected with the input end of the LED driving circuit, the output end of the LED driving circuit is connected to a working loop of LED lamp beads, the working loop is connected with an LED detection circuit, and the LED detection circuit feeds back a monitoring voltage value to the AD detection module. The method has the advantages that the brightness of the LED lamp beads can be adjusted according to user requirements, the user experience is improved, control over the brightness of the LED lamp beads is more accurate, and the color mixing control precision is more uniform; different requirements can be adjusted according to different environment requirements, energy consumption is reduced, the cruising ability is increa
