An LED lighting device with backup switching function has a device main body, configured with at least one LED fitting part and one power supply part. At least one LED component is configured on the LED fitting part and has a main lighting circuit. A backup lighting circuit is fitted inside the same LED component as the main lighting circuit or inside a different LED component. A backup switching processor is electrically connected to and fitted between the main lighting circuit and backup lighting circuit and is connected to the power supply. Based on the automatic detection function of the backup switching processor, in case of short circuit or broken circuit of the main lighting circuit, the switching processor will automatically switch to the backup lighting circuit and maintain continuous lighting of the LED component, and consequently increase the lifecycle of the LED component and reduce repair frequency and cost.
