The size of the light spot can be adjusted by rotating the movable lens component, the operation is simple and convenient, and the structure action range is small. Light passes through the space inside the movable lens assembly, the lens moves axially inside the movable lens assembly, the height of the external structure is kept basically fixed, and the adjustment of the light spot size cannot occupy more space below the lamp cap, so that the lamp cap structure cannot obstruct the work below the lamp cap, and finally the problems that the operation range is large, the operation is inconvenient, and the lamp cap can obstruct the light spot size adjustment of the current desk lamp are solved.

In some embodiments, the light emitting element 2 is disposed coaxially with the lens 41 in order to facilitate directing light emitted by the light emitting element 2 toward the lens 41.

In some embodiments, the movable lens assembly 4 includes a fixed sleeve 42 and a rotating sleeve 43. The fixing sleeve 42 is mounted on the base housing 1, the rotary sleeve 43 is mounted on the fixing sleeve 42, and the lens 41 is mounted on the rotary sleeve 43. The rotary sleeve 43 is rotatably mounted on the fixed sleeve 42, and the lens 41 is mounted on the rotary sleeve 43. The knob rotates the sleeve 43, and the sleeve 43 rotates on the fixed sleeve 42 to drive the lens 41 to move axially, so as to adjust the distance between the lens 41 and the light-emitting element 2.

The fixed sleeve 42, the rotating sleeve 43 and the lens support 412 are sleeved from outside to inside, so that the movable lens assembly 4 is compact in structure, the occupied space in the axial direction is small, and the space below the lamp holder is maximized while the size of a light spot is adjusted.

In some embodiments, the lens body 411 is sleeved by the lens holder 412, so that the inner wall of the lens holder 412 radially limits the lens body 411, thereby improving the mounting stability of the lens body 411 and maintaining the coaxiality with the light emitting element 2.

In some embodiments, the inner wall of the lens holder 412 has an annular step 4122, the edge of the lens holder 412 has a flange 4111, the flange 4111 rests on the annular step 4122, and the annular step 4122 axially supports the flange 4111 to ensure the lens 41 is stably mounted.

In some embodiments, the lens holder 412 has a snap 4123, the lens 41 is axially mounted on the lens holder 412, and after the flange 4111 passes over the snap 4123, the snap 4123 snaps the flange 4111 onto the annular step 4122, so that the snap 4123 and the annular step 4122 form a clamp for the flange 4111, which not only ensures the stable mounting of the lens body 411, but also facilitates the mounting operation.

In some embodiments, the movable lens assembly 4 further includes a protective cover 44. The protective cover 44 is mounted on the lamp head housing 1 and is fitted over the retaining sleeve 42. The protective cover 44 covers the fixing sleeve 42, so that the first limiting groove 421 and the second limiting groove 422 are located inside, thereby preventing the outside from affecting the movement of the limiting pin in the limiting groove, and enabling the movable lens assembly 4 to work smoothly. The rotary sleeve 43 has a knob portion 433 at one end, and the knob portion 433 has a ring-shaped convex structure, and a surface thereof has a pattern capable of increasing friction force, so that the rotary sleeve 43 is rotated by twisting the knob portion 433.
