==LED LAMP AND POWER SOURCE MODULE THEREOF - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240019088 titled 'LED LAMP AND POWER SOURCE MODULE THEREOF

==Simplified Explanation==

The patent application describes an LED lamp and a power supply module. The power supply module consists of a driving circuit, an overvoltage protection (OVP) circuit, and an impedance detection circuit. 

* The OVP circuit samples the driving signal to determine if an overvoltage condition is detected.
* The impedance detection circuit is used to determine if a user touching state is detected.
* When either the OVP condition or the user touching state is detected, the power switch of the driving circuit is controlled to limit the current flowing through it.
* The impedance detection circuit enhances the detection accuracy by comparing signals with a defined level sampled during each pulse.

Potential applications of this technology:

* LED lighting systems in homes, offices, and public spaces.
* Automotive lighting systems.
* Industrial lighting systems.

Problems solved by this technology:

* Protection against overvoltage conditions, which can damage the LED lamp and other connected devices.
* Detection of user touching state, which can help prevent electric shock accidents.

Benefits of this technology:

* Improved safety by limiting the current flow and detecting user touching state.
* Enhanced detection accuracy through impedance comparison.
* Efficient and reliable LED lighting with protection against overvoltage conditions.


==Original Abstract Submitted==

an led lamp and a power supply module thereof are provided. the power supply module includes a driving circuit, a ovp circuit, and an impedance detection circuit. the ovp circuit is configured to determine whether an ovp condition is detected by sampling the driving signal, and the impedance detection circuit is configured to determine whether a user touching state is detected. when either the ovp condition or the user touching state is detected, the power switch of the driving circuit will be controlled to limit the amount of a current flowing through the power switch. in addition, the impedance detection circuit could detect the user touching state by comparing signals with a defined level sampled during each pulse, thus enhancing the detection accuracy.
