1. A replaceable bulb lamp light emitting diode (LED) string device, comprising:
a bulb lamp LED string;
a main memory, storing an address table;
a main controller, electrically connected to the bulb lamp LED string and the main memory;
wherein the main controller executes a detective mode, in the detective mode, the main controller periodically detects a total power consumption value of the bulb lamp LED string, and determines whether a variation of the total power consumption values between two adjacent periods of the bulb lamp LED string increases more than a standby power consumption threshold;
wherein when the variation of the total power consumption values between two adjacent periods of the bulb lamp LED string increases more than the standby power consumption threshold, the main controller executes a new address searching mode to detect a new address of a new bulb lamp LED installed in the bulb lamp LED string;
wherein the main controller further sequentially records the detected new address of the installed new bulb lamp LED into the address table stored in the main memory.
