CCT switchable lamp

A correlated color temperature (CCT) switchable lamp, the lamp comprising:

• a light-emitting assembly comprising a bulb and conductive wires provided at the bottom of the bulb;
• a drive unit comprising a PCB and a CCT switching switch provided on the PCB;
• a base component being provided at the bottom of the light-emitting assembly and accommodating the drive unit;
• and
• a central connection pin, wherein the central connection pin is provided at an axial end of the base component away from the bulb, and the central connection pin is electrically connected to the drive unit by a connection conductive wire extending from the drive unit,
• wherein
• the CCT switching switch is located on a central axis of the CCT switchable lamp and is configured to be rotatable around the central axis to switch the CCT, and
• the CCT switchable lamp further comprises a rotatable annular member, the annular member is connected to the CCT switching switch by means of a connector, the center of the annular member is located on the central axis, and the annular member (i) has an outer surface that is configured to be directly rotated by an end user and (ii) is configured to be rotatable around the central axis in a clockwise direction and in a counterclockwise direction so as to drive rotation of the CCT switching switch.
