The invention discloses an LED lamp with an augmented reality (AR) function. The LED lamp comprises a lamp body, an AR signal loading module, a power module and a mobile terminal, and the power module, the AR signal loading module and the lamp body are electrically connected in sequence. The AR signal loading module comprises an MCU and a transistor, pattern information is written into the MCU, anAR digital signal controls the transistor, accordingly the transistor is turned on or off, a corresponding AR application is mounted on the mobile terminal, and the pattern information is captured through the AR application; the size of the lamp body is worked out, and the position of the lamp body is confirmed; AR information, carried by an LED, in patterns is obtained; the AR application generates the pattern information and then places the corresponding pattern information in the position of the LED lamp in a screen of the mobile terminal; and the AR application performs the step that thepatterns and displacement of the mobile terminal vary synchronously by retrieving mobile terminal gyroscopic data, and the AR function is achieved. According to the LED lamp with the AR function, problems on the design freedom degree of AR lamps are solved, and meanwhile, the data transmission capacity and speed are greatly increased.
