Focus-adjustable lamp

A focus-adjustable lamp, comprising:

• an illuminating mechanism on a top end thereof, and the illuminating mechanism including a light-emitting element, a shield body shielding an outer side of the light-emitting element, a heat dissipating member closely matched with the light-emitting element and a cover body located on the top end of the illuminating mechanism;
• and
• a mounting mechanism located on a bottom end thereof, and defining an insertion part inserted downwardly into a ground,
• wherein the illuminating mechanism further comprises a light-converging cylinder enclosing on a periphery of the shield body, by adjusting a relative position of the light-converging cylinder relative to the shield body in an axial direction, a light spot projected by the light-emitting element on the ground has different sizes, the shield body is a lens having an outer wall movably matched with the light-converging cylinder and an inner wall unmovably matched with the heat dissipating member and the light-emitting element, the shield body has a bottom wall, both of the outer wall and the inner wall are formed by extending upwardly from the bottom wall, the inner wall and the outer wall extend coaxially in the same direction, and spaced apart from each other, and the light-emitting element is located in a spaced region between the inner wall and the outer wall.

A focus-adjustable lamp, providing with an illuminating mechanism on a top end thereof, the illuminating mechanism comprising:

• a light-emitting element;
• a shield body shielding an outer side of the light-emitting element;
• a heat dissipating member closely matched with the light-emitting element;
• and
• a cover body located on the top end of the illuminating mechanism, wherein the illuminating mechanism is further provided with a light-converging cylinder rotationally sleeving the outer side of the shield body, and the light-converging cylinder is capable of rotating back and forth along a circumferential direction of the shield body to adjust a size of a light spot projected by the light-emitting element on a ground, the shield body comprising a lens having an outer wall rotationally matched with the light-converging cylinder and an inner wall fixedly matched with the heat dissipating member and the light-emitting element, the outer wall is provided with a plurality of buckling parts protruding toward a direction of a central axis of the illuminating mechanism and a plurality of intermittently arranged threaded parts, and the buckling parts are hooked in a fastening groove disposed in an outer side of the heat dissipating member, the threaded parts and the buckling parts are alternately arranged in a circumferential direction of the outer wall.
