Zoom lamp

A zoom lamp, comprising:

• a lamp body defining a receiving groove, wherein an inner wall of the lamp body defines an annular latching groove coaxial with the receiving groove and a plurality of sliding grooves extending along an axial direction of the lamp body;
• a light emitting component received in the receiving groove;
• a movable ring comprising a plurality of guiding posts protruding from an outer wall thereof and a plurality of resilient members connected to the plurality of guiding posts correspondingly, wherein the guiding post extends along an axial direction of the movable ring to engage the sliding grove which is slidably positioned in the lamb body, the resilient member is configured to provide a reversed resistance which is opposite to a sliding direction of the guiding post for the guiding post;
• a lens fixed to the movable ring;
• a rotation ring, wherein an external wall of the rotation ring is provided with a latching hook sliding along the annular latching groove, the rotation ring defines a plurality of inclined grooves, the plurality of guiding posts slide in the plurality of inclined grooves correspondingly and resist bottoms of the plurality of inclined grooves;
• wherein when the rotating ring rotates, the guiding post is guided in the inclined groove to slide along the sliding groove, thereby driving the lens to move adjacent to or away from the light emitting component.
