A COB packaging for embedding a thermal protection IC (2) and a packaging method thereof utilizing the following technical solution: the COB packaging for embedding a thermal protection IC comprises an LTCC substrate (1), a thermal protection IC (2), a temperature sensor (3), and an LED chip (4). The LTCC substrate (1) is made up of two or more layers of green ceramic sheets laminated together. The thermal protection IC (2) and the temperature sensor (3) are disposed in the LTCC substrate (1), and the LED chip (4) is fixed on the LTCC substrate (1). The temperature sensor (3) and the LED chip (4) are separated by only a single layer of green ceramic. The thermal protection IC (2) and the temperature sensor (3) are electrically connected. When the temperature of the LTCC substrate (1) exceeds a temperature limit, information is fed back to the thermal protection IC (2) by the temperature sensor (3), and the thermal protection IC (2) performs step-down regulation on the output current, thereby ...
