When the lighting switching is performed for the first time, if the second lighting lamp heats up quickly and an over-temperature situation occurs during the period when the third terminal of the first counter IC1 outputs a high level, it will cause the first comparator A1 to still output a high level, and when the time for the first comparator A1 to output a high level exceeds the timing duration set by the eighth resistor R8, the first capacitor C1 and the ninth resistor R9, the third switching transistor VT3 will conduct, so that the first switching transistor VT1 conducts, and then controls the first power transistor Q1 to cut off for power-off protection.
