1. A dimmable and color temperature-adjustable LED lamp, comprising a ceiling disk, an LED light source assembly arranged on the ceiling disk and a lampshade arranged under the LED light source assembly, the LED light source assembly consisting of an LED board and a driver providing low-voltage power for the LED board, characterized in that:

  • the LED board is provided with double-color temperature LED lamp beads;

    the driver comprises a drive housing and a driving circuit board arranged inside the drive housing;

    the driving circuit board comprises an input power line, a high-voltage input module, a wireless control module, a dimming module, a color-temperature adjusting module, a voltage transformation module, a low-voltage output module and an output power line;

    the LED lamp further comprises an independent wireless remote control device;

    the wireless control module is used for performing wireless paired control together with the wireless remote control device;

    the high-voltage input module is respectively connected with the input power line and the wireless control module;

    the wireless control module is respectively connected with the dimming module and the color temperature-adjusting module;

    the wireless control module is used respectively for controlling the illumination brightness and color temperature change of the double-color temperature LED lamp beads;

    the voltage transformation module is respectively connected with the wireless control module and the low-voltage output module;

    the output power line is connected to the low-voltage output module;

    high-voltage power is input to the high-voltage input module via the input power line;

    the input voltage is regulated via the wireless control module;

    the high-voltage power is converted into safe low-voltage power via the voltage transformation module; and

    then the safe low-voltage power is output via the low-voltage output module and finally transmitted to the LED board via the output power line.
