Lamp and lighting equipment

A lamp, comprising:

• a fixed base;
• a light source fixed in the fixed base;
• a lens, wherein a light output surface of the light source faces the lens,
• a movable ring, wherein the lens is fixedly connected to the movable ring, one of the fixed base and the movable ring comprises a sliding block, another of the fixed base and the movable ring comprises a sliding groove, two ends of the sliding groove are spaced apart along a radial direction of the lens and are spaced apart along a circumferential direction of the lens, the sliding block is slidably arranged in the sliding groove, and when the movable ring is rotated relative to the fixed base, the sliding block slides along the sliding groove, to change a distance between the lens and the light source;
• and
• a light shield detachably connected to an end of the movable ring away from the light source, wherein the light shield is arranged at a periphery of the lens,
• wherein the movable ring comprises an annular connection portion, the connection portion comprises an end face and a first outer peripheral surface, the end face is located at an end of the connection portion away from the light source, and the first outer peripheral surface surrounds the end face, and
• wherein the light shield comprises a buckle, the first outer peripheral surface is provided with an engagement groove, the engagement groove comprises an axial segment and a circumferential segment, the axial segment extends along an axial direction of the movable ring, the circumferential segment extends along a circumferential direction of the movable ring, the buckle is slidable in the axial segment and the circumferential segment, one end of the axial segment extends to the end face to form an opening allowing the buckle to pass through on the end face, and another end of the axial segment is in communication with one end of the circumferential segment.

A lighting equipment, comprising:

• a plurality of lamps, each of the plurality of lamps comprising:
• a fixed base;
