1. An LED driving structure, comprising an LED module, a power supply circuit, a voltage stabilizing circuit, a temperature compensation circuit and a gallium nitride field-effect transistor that are electrically connected, wherein:the power supply circuit is configured to supply a current to the LED module;
the voltage stabilizing circuit includes a rectifying diode, a resistor and a Zener diode, and is connected to a gate of the gallium nitride field-effect transistor through the temperature compensation circuit for providing a stable voltage;
the temperature compensation circuit includes at least one resistor connected to the voltage stabilizing circuit, a thermistor and a transistor connected to the gate of the gallium nitride field-effect transistor to compensate for the voltage when there is a change in temperature, so that the LED module maintains power stably when heat is generated after being energized.
