1. An LED light control circuit, comprising:
an LED light switch control module, configured for connecting with a switch signal chip and an LED light assembly, so that a switch signal output by the switch signal chip controlling the LED light assembly to turn on and off;
an overcurrent protection module connected with the LED light switch control module and configured for detecting overcurrent of the LED light assembly and disconnecting current of the LED light switch control module, so that the LED light assembly being turned off by the LED light switch control module;
an overtemperature protection module connected with the LED light switch control module and configured for detecting overtemperature of the LED light control circuit and disconnecting current of the LED light switch control module, so that the LED light assembly being turned off by the LED light switch control module; and
an under-voltage protection module connected with an LED light assembly voltage input and the LED light switch control module, configured for detecting an input voltage of the LED light assembly and disconnecting current of the LED light switch control module when the input voltage is too low, so that the LED light assembly being turned off by the LED light switch control module.
