Angle-adjustable lamp

The invention provides an angle-adjustable lamp and relates to the technical field of lighting. An angle-adjustable lamp comprises a fixing socket which is provided with a lamp hole, a rotating ring which rotates inside the protrusion of the outer edge of lamp hole, a fixing ring reversely sleeved on the protrusion and the lamp body connected to the rotating ring through two protrusions; by arranging the annular protrusion in the rim of the lamp hole and embedding rotating ring inside the protrusion, the rotation of the rotating ring along the center of lamp hole is ensured, and the limitation of rotation angle of lamp is extended; by arranging the annular fixing ring in the protrusion, raising and falling motion of rotating ring can be prevented effectively, therefore, the rotation process becomes more smooth.
