Abstract
The invention provides dimmable and color temperature-adjustable LED lamps in the LED illumination field, comprising: a ceiling disk; an LED light source assembly on the disk, comprising an LED board with double-color temperature lamp beads and a driver providing low-voltage power for the board; and a lampshade, wherein the driver comprises: a drive housing; and a driving circuit board comprising 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 driver with dimming and color temperature-adjusting modules can select color temperature conversion and adjust light source brightness of each color temperature section. LED lamp beads with two different color temperatures are simultaneously distributed on the same board for the consumer to adjust and convert different color temperature functions, enriching flexible selection requirement for LED lamp functions.
