Abstract
An LED lamp with a rotatable lamp holder for adjusting color temperature includes a bulb shell, a lamp holder, a light source assembly, and a driver circuit board. The bulb shell and the lamp holder are combined to form a sealed space for accommodating the light source assembly and the driver circuit board. The driver circuit board comprises a rotatable switch, and the rotatable switch is fixedly connected to a rotatable knob on the lamp holder through a rotating shell, which enables the rotatable knob to drive the rotatable switch to rotate by an external force.
