LED lamp and misuse warning module thereof

An LED lamp, comprising:

• at least two pins, a first pin and a second pin, configured to receive an external driving signal;
• a power supply module, electrically connected to the first pin and the second pin, and configured to execute power conversion of the external driving signal to generate a driving signal;
• an LED module, configured to receive the driving signal to light up;
• an installation detection module, configured to detect current in a power loop and determine whether to limit the current of the power loop based on the current level of the power loop;
• an impedance adjusting module, electrically connected to the first pin and the second pin, and configured to adjust impedance of the power loop to affect the determination of the installation detection module, wherein when a first resistor is connected in series in the power loop, the installation detection module limits the current of the power loop and the LED lamp cannot be lit normally;
• and when at least two or more of the LED lamps are connected in parallel, the installation detection module does not limit the current of the power loop and the plurality of the LED lights are lit normally;
• and
• wherein, the external power supply signal is supplied to the LED lamp through the power loop, and the first resistor is connected in series with the plurality of LED lamps,
• wherein the installation detection module comprises:
• a detection pulse generating module, configured to generate a pulse signal;
• a switching circuit, coupled to the power loop, and configured to conduct or cut off based on the pulse signal;
• and
• a detection determining circuit, configured to detect current level of the power loop when the switching circuit is conducted and output the first detection signal when the current level is greater than a set threshold,
• wherein the switching circuit is turned on based on the first detection signal.
