[0035] like Figures 1 to 12 As shown, a desk lamp 100 includes: a lamp base 20, a lamp head 10, and a lamp holder 30. The lamp holder 30 connects the lamp base 20 and the lamp head 10. The lamp head 10 includes: an LED light panel with multiple LEDs, a mounting base 11, and a slide rail 12. The LED light panel is mounted to the front of the mounting base 11. The slide rail 12 is mounted to the back of the mounting base 11. The lamp holder 30 is equipped with a slider 301. The slider 301 includes: a top plate portion 3011 and two sliding sleeve portions 3012. The top plate portion 3011 is used for mounting to the lamp holder 30. The sliding sleeve portions 3012 are used for guiding sliding. The top plate portion 3011 and the two sliding sleeve portions 3012 are integrally formed. The two sliding sleeve portions 3012 are connected to both ends of the top plate portion 3011. The sliding sleeve portion 3012 includes: a vertical plate portion 3013 and an inner horizontal plate portion 3014. The vertical plate portion 3013 connects the inner horizontal plate portion 3014 and the top plate portion 3011. The vertical plate portion 3013, the inner horizontal plate portion 3014, and the top plate portion 3011 together form a sliding groove 3015.

[0036] The slide rail plate 12 includes a base plate 121 and two slide rails 122. The base plate 121 is used to mount to the mounting base 11. The slide rails 122 are used for guiding sliding. The base plate 121 and the two slide rails 122 are integrally formed. The two slide rails 122 are connected to both ends of the base plate. The slide rails 122 include a vertical wall 123 and an outer horizontal plate 124. The vertical wall 123 connects the outer horizontal plate 124 and the base plate 121. The outer horizontal plate 124 slides within the slide groove 3015. The upper and lower sides of the outer horizontal plate 124 respectively have upper sliding ribs 125 and lower sliding ribs 126 protruding towards the groove wall of the slide groove 3015. The vertical wall 123 has side sliding ribs 127 protruding towards the end face of the inner horizontal plate 3014.

[0037] In one specific implementation, the lamp holder 10 also includes a lamp holder housing 13. The mounting base 11 is located inside the lamp holder housing 13.

[0038] In one specific embodiment, the lamp holder 30 includes: a vertical rod assembly 31, a horizontal rod 32, an upward base 33, and an upward frame 34. The vertical rod assembly 31 consists of several telescopic rod sections. The bottom of the vertical rod assembly 31 is mounted to the lamp holder 20. The top of the vertical rod assembly 31 is rotatably mounted to one end of the horizontal rod 32. The upward base 33 is mounted to the other end of the horizontal rod 32. The upward frame 34 is rotatably mounted to the upward base 33. A slider 301 is fixed to the upward frame 34. The horizontal rod 32 is vertically aligned with the axis of rotation of the vertical rod assembly 31. The upward frame 34 is horizontally aligned with the axis of rotation of the upward base 33.

[0039] In one specific implementation, one of the tilting frame 34 and the tilting seat 33 has a front positioning protrusion 331 and a rear positioning protrusion 332. The other of the tilting frame 34 and the tilting seat 33 is fixed with a positioning member 35. The positioning member 35 has a positioning semi-ring 351. The tilting frame 34 has a first working position, a second working position, and a third working position relative to the tilting seat 33. In the first working position, the front end and the rear end of the positioning semi-ring 351 abut against the front positioning protrusion 331 and the rear positioning protrusion 332, respectively. When the tilting frame 34 rotates relative to the tilting seat 33 from the first working position to the second working position, the front end of the positioning semi-ring 351 passes the front positioning protrusion 331 and abuts against the rear positioning protrusion 332. When the tilting frame 34 rotates relative to the tilting seat 33 from the first working position to the third working position, the rear end of the positioning semi-ring 351 passes the rear positioning protrusion 332 and abuts against the front positioning protrusion 331.

[0040] In one specific implementation, the rotation direction of the tilting frame 34 relative to the tilting seat 33 from the first working position to the second working position is opposite to the rotation direction of the tilting frame 34 relative to the tilting seat 33 from the first working position to the third working position.

[0041] In one specific implementation, the rotation angle of the tilting frame 34 relative to the tilting seat 33 from the first working position to the second working position is equal to the rotation angle of the tilting frame 34 relative to the tilting seat 33 from the first working position to the third working position.

[0042] In one specific implementation, the lamp head 10 is horizontally positioned in the first working position.

[0043] In one specific implementation, the inverted seat 33 is rotatably mounted to the crossbar 32. The axis of rotation of the inverted seat 33 relative to the crossbar 32 is vertically arranged.

[0044] In one specific embodiment, the vertical rod assembly 31 includes an inner slide rod 311 and an outer slide rod 312. The inner slide rod 311 is disposed within the outer slide rod 312 and slides relative to the outer slide rod 312. One of the inner slide rod 311 and the outer slide rod 312 is provided with a plurality of locking holes. The other of the inner slide rod 311 and the outer slide rod 312 is fitted with a locking pin 3141. The locking pin 3141 is inserted into the locking holes to lock the inner slide rod 311 and the outer slide rod 312.

[0045] In one specific implementation, the outer slide bar 312 is fitted with a locking seat 313. A locking member 314 is rotatably connected to the locking seat 313. The locking member 314 has an unlocking part 3142 and a locking pin 3141. The unlocking part 3142 is pressed by the user. The locking pin 3141 is inserted into a keyhole. The unlocking part 3142 and the locking pin 3141 are located on opposite sides of the axis of rotation of the locking member 314 relative to the locking seat 313. The locking seat 313 has a locking seat plastic spring 3131. The locking seat plastic spring 3131 applies a force to the locking member 314 to prevent the locking pin 3141 from disengaging from the keyhole. The locking seat plastic spring 3131 abuts against the locking member 314. When the user presses the unlocking part 3142, the locking member 314 rotates relative to the locking seat 313, applying a force to the plastic spring 3131 of the locking seat, causing the plastic spring 3131 of the locking seat to elastically deform, and the locking pin 3141 is pulled out of the keyhole. When the unlocking part 3142 is not subjected to external force applied by the user, when the locking pin 3141 is aligned with the keyhole, the plastic spring 3131 of the locking seat pushes the locking member 314 to rotate relative to the locking seat 313, and the locking pin 3141 is inserted into the keyhole.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
