  • Publication number: 20210136892
    Abstract: A light emitting diode (LED) lamp includes at least one LED and an LED driver. The LED driver includes at least two terminals, a burning processor, and an address memory. The at least two terminals have a power input terminal and a power output terminal. The power input terminal and the power output terminal are externally coupled to a power line. The burning processor receives a burning activation data of a burning signal through the power input terminal or the power output terminal, and directly and externally receives a burning address data of the burning signal without from the power line. When a burning function of the burning processor is activated by the burning activation data, the burning processor converts the burning address data into a local address data and burns the local address data into the address memory.
