In the above exemplary embodiment, the lamp cap structure adjusts the distance between the lens and the light emitting element by rotating the adjusting assembly, so as to change the diffusion effect degree of the lens on the light emitted by the light emitting element, and finally achieve the effect of changing the size of the light spot. The adjustment of the size of the light spot can be realized by rotating the adjusting component, the operation is simple and convenient, and the structure action range is small. Light passes through the space inside the adjusting component, the lens axially moves on the adjusting component, the height of the external structure is basically fixed, and the adjustment of the light spot size cannot occupy the space below the lamp holder greatly, so that the lamp holder structure cannot obstruct the work below the lamp holder, and finally the problems that the operation range is large, the operation is inconvenient and the lamp holder can obstruct in 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 adjustment assembly 3 comprises a fixed sleeve 31 and a rotating sleeve 32. The fixing sleeve 31 is mounted on the base housing 1, the rotary sleeve 32 is mounted on the fixing sleeve 31, and the lens 4 is mounted on the rotary sleeve 32. The rotary sleeve 32 is rotatably mounted on the fixed sleeve 31, and the lens 4 is mounted on the rotary sleeve 32. The knob rotates the sleeve 32, the sleeve 32 rotates on the fixed sleeve 31, and drives the lens 4 to move axially, so as to adjust the distance between the lens 4 and the light-emitting element 2.

The axial movement of the lens 4 can be done in two ways: in the first way, the lens 4 is slidably mounted on the rotating sleeve 32, and the rotating sleeve 32 drives the lens 4 to axially slide thereon; in the second mode, the lens 4 is fixedly mounted on the rotary sleeve 32, and the rotary sleeve 32 is axially moved while rotating, so that the lens 4 is axially moved along with the rotary sleeve.

In some embodiments, to enable the lens to slide on the rotating sleeve 32, the lens 4 includes a lens body 41 and a lens holder 42. The lens holder 42 is mounted on the rotary sleeve 32 and can slide on the rotary sleeve 32. The lens body 41 is mounted on the lens holder 42 so as to move with the lens holder 42.

The lens holder 42 is provided with a first limit pin 421, and the first limit pin 421 is slidably mounted in the first limit groove 311 and the driving groove 321. When the rotating sleeve 32 is rotated, the first limiting groove 311 disposed axially enables the lens holder 42 to move axially only through the first limiting pin 421, and prevents the lens holder from rotating with the rotating sleeve 32; the spiral driving groove 321 pushes the lens holder 42 to move axially through the first limit pin 421, so as to adjust the distance between the lens 4 and the light emitting element 2.

In some embodiments, the side wall of the fixing sleeve 31 has a second limiting groove 312, and the second limiting groove 312 is circumferentially disposed, i.e., the circumference of the second limiting groove 312 is coaxial with the fixing sleeve 31. The rotating sleeve 32 is provided with a second limiting pin 322, and the second limiting pin 322 is slidably mounted in the second limiting groove 312. The second limit groove 312 enables the rotary sleeve 32 to rotate only and not to move axially through the second limit pin 322, so that the assembly connection between the rotary sleeve 32 and the fixed sleeve 31 is stable.

In some embodiments, the rotating sleeve 32 is threaded onto the fixed sleeve 31 in order to achieve axial movement of the lens 4 with the rotating sleeve 32. The rotating sleeve 32 is rotated, the screw threads convert the rotating motion into linear motion, and the rotating sleeve 32 moves axially, so that the lens 4 moves axially along with the rotating sleeve, and the adjustment of the distance between the lens 4 and the light-emitting element 2 is realized.

In some embodiments, the fixed sleeve 31 is sleeved on the rotating sleeve 32, so that the inner wall of the fixed sleeve 31 radially limits the rotating sleeve 32 to play a role in guiding axial movement; the lens support 42 is sleeved with the rotary sleeve 32, so that the inner wall of the rotary sleeve 32 radially limits the lens support 42 and plays a role in guiding axial movement. The fixed sleeve 31, the rotating sleeve 32 and the lens support 42 are sleeved from outside to inside, so that the adjusting assembly 3 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 41 is sleeved with the lens support 42, so that the inner wall of the lens support 42 radially limits the lens body 41, thereby improving the mounting stability of the lens body 41 and maintaining the coaxiality with the light emitting element 2.

In some embodiments, the inner wall of the lens holder 42 has an annular step 422, the edge of the lens body 41 has a flange 411, the flange 411 rests on the annular step 422, and the annular step 422 axially supports the flange 411 to ensure the stable mounting of the lens body 41.

In some embodiments, the lens holder 42 has a snap 423, the lens body 41 is axially installed on the lens holder 42, and after the flange 411 passes over the snap 423, the snap 423 snaps the flange 411 on the annular step 422, so that the snap 423 and the annular step 422 form a clamp for the flange 411, which not only ensures that the lens body 41 is stably installed, but also is convenient to install and operate.

In some embodiments, the adjustment assembly 3 further comprises a protective cover 33. The protective cover 33 is mounted on the lamp cap housing 1 and is fitted over the fixing sleeve 31. The protective cover 33 covers the fixing sleeve 31, so that the first limiting groove 311 and the second limiting groove 312 are located inside, thereby preventing the outside from influencing the movement of the limiting pin in the limiting groove, and ensuring the smooth operation of the adjusting assembly 3. The rotary sleeve 32 has a knob portion 323 at one end thereof, and the knob portion 323 has a ring-shaped convex structure, and has a pattern on the surface thereof to increase friction force, so that the rotary sleeve 32 is rotated by twisting the knob portion 323. The knob part 323 is located outside the protection cover 33 and attached to the end face of the protection cover 33, so as to avoid the shielding of the protection cover 33 and ensure the convenience of the rotation operation.

The heat generated by the operation of the light-emitting element 2 is quickly dissipated through the heat dissipation member 12, so that the high-temperature damage of the light-emitting element 2 is avoided, and the service life of the light-emitting element is ensured.

In some embodiments, the lamp head housing 1 further comprises a light source holder 13, the light source holder 13 being mounted on the heat sink 12. The heat sink 13 has an installation groove 131, and the light emitting element 2 is installed in the installation groove 131, so that the installation groove 131 performs spacing fixation on the light emitting element 2, thereby improving installation stability. The light emitting element 2 can directly transmit heat to the heat dissipation member 12, and can also transmit heat to the heat dissipation member 12 through the light source support 13, so that the light source support 13 increases heat transmission efficiency and improves heat dissipation effect.

In some embodiments, the heat sink 12 has the protrusion 121, the light source support 13 has the assembly groove 132, and the protrusion 121 is inserted into the assembly groove 132, so as to improve the installation firmness of the light source support 13, increase the contact area between the light source support 13 and the heat sink 12, improve the heat transfer efficiency, and enhance the heat dissipation effect.
