[0043] Please refer to Figure 1 This embodiment provides a lamp 010, which may be a wall lamp; of course, in other embodiments, the lamp 010 may also be a table lamp, a chandelier, etc., which is not specifically limited here. The following will take the wall lamp as an example for detailed description.

[0044] The lamp 010 of this embodiment includes a base mechanism 300, a lamp pole mechanism 200 and a lamp holder mechanism 100. The two ends of the lamp pole mechanism 200 are respectively connected to the base mechanism 300 and the lamp holder mechanism 100; the base mechanism 300 can be used to be installed on the wall, and the lamp holder mechanism 100 can emit light for lighting.

[0045] Please refer to Figure 1 and Figure 2 In order to enrich the functions of the lamp 010, the base mechanism 300 of the present embodiment includes a base shell 310 and a socket assembly 340. The base shell 310 is provided with a plug hole 314. The socket assembly 340 is assembled in the base shell 310 and is distributed relative to the plug hole 314. With such a configuration, the plug of the electrical device can be plugged into the plug hole 314, so that the plug of the electrical device can be plugged into the socket assembly 340 through the plug hole 314 and draw power.

[0046] Optionally, the base housing 310 includes a bottom shell 311, a pressure plate 312 and a cover 313. The bottom shell 311 has an installation space, and the bottom shell 311 is used to be installed at an installation location such as a wall. The socket assembly 340 is installed in the installation space. The pressure plate 312 is connected to the bottom shell 311 to prevent the socket assembly 340 from leaving the installation space. The pressure plate 312 is provided with a through hole 315, and the cover 313 is provided with a plug hole 314. The cover 313 is connected to the bottom shell 311 and covers and blocks the side of the pressure plate 312 away from the installation space. The plug hole 314, the through hole 315 and the plug hole of the socket assembly 340 are opposite and connected in sequence. With such a configuration, the base mechanism 300 can be used as a wall socket to provide power to other electrical devices.

[0047] In order to improve the stability of the socket assembly 340 being assembled on the base housing 310 , the socket assembly 340 is snap-fitted with the bottom shell 311 .

[0048] Of course, in other embodiments, the socket assembly 340 may also be connected to the bottom shell 311 via fasteners such as bolts.

[0049] The connection methods of the pressing plate 312 and the surface cover 313 with the bottom shell 311 include but are not limited to clamping and connection with fasteners such as bolts.

[0050] It should be noted that the number of the plug holes 314 and the through holes 315 is adapted to the type of the socket assembly 340. For example, when the socket assembly 340 is a three-hole socket, the number of the plug holes 314 and the through holes 315 is three respectively; when the socket assembly 340 is a two-hole socket, the number of the plug holes 314 and the through holes 315 is two respectively; and when the socket assembly 340 is a five-hole socket, the number of the plug holes 314 and the through holes 315 is five respectively.

[0051] In order to flexibly adjust the lighting height of the lamp head mechanism 100; please refer to Figure 1 and Figure 2 The lamp pole mechanism 200 of this embodiment includes a fixed rod 210, a locking assembly 220 and an adjusting rod 230. One end of the adjusting rod 230 is connected to the lamp holder mechanism 100, and the other end of the adjusting rod 230 is slidably connected to the fixed rod 210 through the locking assembly 220. The locking assembly 220 has an unlocked state and a locked state. When the locking assembly 220 is in the unlocked state, the adjusting rod 230 can slide relative to the fixed rod 210 to adjust the length of the adjusting rod 230 extending relative to the fixed rod 210. When the locking assembly 220 is in the locked state, the relative position of the adjusting rod 230 and the fixed rod 210 is locked. In this way, the height of the lamp holder mechanism 100 can be adjusted by switching the locking assembly 220 to the unlocked state and sliding the adjusting rod 230 relative to the fixed rod 210, so as to adjust the lighting height and meet more user needs.

[0052] Optionally, see Figure 3 , Figure 4 and Figure 5 The locking assembly 220 includes an expansion plug 222 and a threaded member 221. The threaded member 221 is sleeved on the outside of the adjusting rod 230 and is threadedly connected to the fixing rod 210. A portion of the expansion plug 222 is clamped between the adjusting rod 230 and the fixing rod 210, and another portion of the expansion plug 222 is clamped between the threaded member 221 and the adjusting rod 230. When the threaded member 221 is tightened along a first direction, the threaded member 221 squeezes the expansion plug 222 so that the expanded expansion plug 222 clamps the adjusting rod. 230, thereby locking the relative positions of the adjusting rod 230 and the fixing rod 210, that is, fixing the height of the lamp holder mechanism 100; when the threaded member 221 is loosened along a second direction opposite to the first direction, the pressure applied by the threaded member 221 to the expansion plug 222 is released, and the expansion plug 222 no longer clamps the adjusting rod 230, so that the adjusting rod 230 can slide relative to the fixing rod 210, that is, adjusting the length of the adjusting rod 230 extending relative to the fixing rod 210, that is, adjusting the height of the lamp holder mechanism 100.

[0053] The threaded member 221 includes but is not limited to a nut with internal threads. The first direction may be clockwise, and the second direction may be counterclockwise, or the first direction may be counterclockwise, and the second direction may be clockwise, which is not specifically limited here.

[0054] It should be understood that in other embodiments, the locking assembly 220 includes a bolt, and the adjusting rod 230 can be slidably inserted into the fixing rod 210; the bolt is threadedly connected to the fixing rod 210, and one end of the bolt is connected to a bolt head, the bolt head is located on the outside of the fixing rod 210, and the other end of the bolt extends into the fixing rod 210 and can abut against the adjusting rod 230; when the bolt is loosened so that the bolt no longer abuts against the adjusting rod 230, the adjusting rod 230 can slide relative to the fixing rod 210; when the bolt is tightened so that the bolt abuts against the adjusting rod 230, the relative position of the adjusting rod 230 and the fixing rod 210 is locked.

[0055] Optionally, the adjustment rod 230 is configured to be bendable; illustratively, the adjustment rod 230 includes a gooseneck tube, or a plastic-coated metal hose, etc., which is not specifically limited here. In this way, the irradiation range and direction of the lamp head mechanism 100 can be adjusted by bending the adjustment rod 230 to meet more lighting needs.

[0056] Please refer to Figure 2 , Figure 6 and Figure 7The lamp 010 of this embodiment further includes a light source driving module 320 and a power cord 330. The fixing rod 210 is connected to the base housing 310. The two ends of the power cord 330 are respectively connected to the light source driving module 320 and the lamp holder mechanism 100. In this way, the light source driving module 320 can be used to supply power to the lamp holder mechanism 100.

[0057] Optionally, the light source driving module 320 can be stably assembled to the bottom shell 311 by means of a snap connection. Of course, in other embodiments, the light source driving module 320 can also be connected to the bottom shell 311 by fasteners such as bolts, which is not specifically limited here.

[0058] Optionally, see Figure 2 The lamp 010 further includes a switch assembly 350, which is mounted on the cover 313 and electrically connected to the light source driving module 320; thus, the switch assembly 350 can drive the light source driving module 320 to be turned on and off, thereby realizing the on and off of the lamp holder mechanism 100, that is, controlling the on and off of the lamp holder mechanism 100. The switch assembly 350 includes but is not limited to a touch switch and a button switch.

[0059] It should be noted that the light source driving module 320 and the socket assembly 340 are configured to be independently electrically connected to a power source such as the mains, and their specific connection methods are similar to those in the related art and will not be described in detail here.

[0060] In order to ensure the reliability of the lamp holder mechanism 100 to obtain power, the power cord 330 is passed through the interior of the fixing rod 210 and the adjusting rod 230. This arrangement ensures that the power cord 330 is not easily accidentally disconnected by external force, and ensures the reliability of the electrical connection between the lamp holder mechanism 100 and the light source driving module 320 through the power cord 330.

[0061] Furthermore, the power cord 330 is a spring power cord. In this way, when the adjustment rod 230 is extended or bent, the spring power cord can be stretched, shortened or bent as the state of the adjustment rod 230 changes, which can ensure that the lamp holder mechanism 100 is reliably electrically connected to the light source driving module 320 through the power cord 330, and can also improve the problems of messy wiring, easy entanglement, and scratches on the power cord 330.

[0062] It should be understood that in other embodiments, the power cord 330 is not a spring power cord, and the length of the power cord 330 can be configured to be greater than the total length of the fixed rod 210 and the adjustment rod 230; in this way, the problem of the power cord 330 being easily disconnected from one of the lamp head mechanism 100 and the light source driving module can be improved when the adjustment rod 230 is extended or retracted relative to the fixed rod 210.

[0063] Optionally, see Figure 2, one end of the fixing rod 210 away from the adjusting rod 230 is clamped between the bottom shell 311 and the pressing plate 312; with such a configuration, the fixing rod 210 can be assembled through the bottom shell 311 and the pressing plate 312, which is beneficial to reducing the investment in other parts used to fix the fixing rod 210 to the bottom shell 311, which is beneficial to reducing the assembly process and reducing the production cost of the lamp 010.

[0064] Furthermore, in order to improve the stability of the fixing rod 210 assembled on the base shell 310, the bottom shell 311 is provided with a first groove, the pressure plate 312 is provided with a second groove, the fixing rod 210 is inserted between the first groove and the second groove, and is interference fit with the first side and the second side.

[0065] Optionally, along the length extension direction of the first groove, the groove wall of at least one of the first groove and the second groove is connected to a limiting member, and the end of the fixing rod 210 away from the adjusting rod 230 abuts against the limiting member to ensure the stability of the fixing rod 210 inserted into the first groove and the second groove.

[0066] Of course, in other embodiments, the fixing rod 210 may also be connected to one of the bottom shell 311 and the pressure plate 312 by fasteners such as bolts, which is not specifically limited here.

[0067] Alternatively, in other embodiments, one end of the fixing rod 210 away from the adjusting rod 230 may also be clamped between the bottom shell 311 and the surface cover 313, which is not specifically limited herein.

[0068] Please refer to Figure 6 and Figure 8 The lamp head mechanism 100 of this embodiment includes a lamp head 110, a button 120, a light source assembly 130 and a first lens 140, the button 120 and the lamp head 110 are slidably connected; the light source assembly 130 is assembled on the lamp head 110, the button 120 is transmission-connected to the first lens 140, and the first lens 140 is located on the light emitting side of the light source assembly 130; wherein, when the button 120 slides relative to the lamp head 110 under the action of external force, it can drive the first lens 140 to move so as to adjust the distance between the first lens 140 and the light source assembly 130.

[0069] In this way, the lamp head mechanism 100 can drive the first lens 140 to move and adjust the distance between the first lens 140 and the light source assembly 130 by sliding the button 120 relative to the lamp head 110, thereby achieving the purpose of adjusting the light beam angle; wherein, when the first lens 140 is close to the light source assembly 130, the light beam angle emitted through the first lens 140 is larger and has a wider illumination range; when the first lens 140 is away from the light source assembly 130, the light beam angle emitted through the first lens 140 is smaller and has a relatively narrow illumination range. In this way, the user's various lighting needs can be met.

[0070] Furthermore, the lamp holder 110 is provided with a mounting cavity 111 and a socket 112 connected to the mounting cavity 111, the button 120 is slidably inserted into the socket 112, and the button 120 is configured to slide back and forth along the length extension direction of the socket 112; the light source assembly 130 and the first lens 140 are both assembled in the mounting cavity 111. Assembling the light source assembly 130 and the first lens 140 in the mounting cavity 111 of the lamp holder 110 can make the structure of the lamp holder mechanism 100 more compact, which is conducive to the miniaturization design of the lamp holder mechanism 100.

[0071] Optionally, the insertion hole 112 is a waist-shaped hole or a rectangular hole, which is not specifically limited here.

[0072] Furthermore, the light source assembly 130 includes a light source module 131 and a second lens 132, both of which are mounted in the mounting cavity 111 of the lamp holder 110, and the second lens 132 is located between the light source module 131 and the first lens 140, that is, the second lens 132 is located on the light emitting side of the light source module 131, and the first lens 140 is located on the light emitting side of the second lens 132; the light source module 131 is electrically connected to the light source driving module 320 via a power line 330. The light source module 131 includes but is not limited to an LED light board; the setting of the second lens 132 can constrain the light emitting angle of the light source module 131 and filter out stray light in the light source to improve the lighting effect.

[0073] It should be noted that the electrical connection methods of the power line 330 and the light source driving module 320 and the light source module 131 include but are not limited to welding, connection with conductive bolts, and connection with male and female terminals, which are not specifically limited here.

[0074] Please refer to Fig. 9 The button 120 of this embodiment includes a button body 121 and a buckle 122 connected to the button body 121. The buckle 122 is inserted into the insertion hole 112 and extends into the installation cavity 111 to be engaged with the first lens 140. This arrangement ensures that the button 120 is assembled to the lamp holder 110 and that the button 120 and the first lens 140 are easy to operate in transmission cooperation.

[0075] Furthermore, the button 120 includes two buckles 122, both of which are connected to the button body 121, and the two buckles 122 are opposite and spaced apart, and both ends of the two buckles 122 away from the button body 121 have snap-fitting convex teeth, and the snap-fitting convex teeth of the two buckles 122 are arranged opposite to each other; the first lens 140 is provided with an assembly hole, and the two buckles 122 are inserted into the assembly hole after passing through the insertion hole 112, and the snap-fitting convex teeth of the two buckles 122 are snap-fitted to the first lens 140. In this way, the stability of the assembly of the button 120 can be ensured, and the reliability of the button 120 driving the first lens 140 to approach or move away from the light source assembly 130 can be ensured.

[0076] Optionally, see Fig. 9 The hole wall of the socket 112 is provided with a plurality of latch teeth 113, and the plurality of latch teeth 113 are sequentially distributed along the length extension direction of the socket 112; the button 120 is connected with a protrusion 123, specifically, the protrusion 123 is connected to the buckle 122; when the button 120 slides along the length extension direction of the socket 112 under the action of an external force, the protrusion 123 sequentially passes over the plurality of latch teeth 113. With such a configuration, when the button 120 is slid relative to the lamp body, a jerky gear feel and a slight sound can be generated, so that the user's experience is better.

[0077] Furthermore, the protrusion 123 can be made of an elastic material, such as plastic, rubber, silicone, etc. When the protrusion 123 abuts against the latch tooth 113, the protrusion 123 can be deformed, and when the protrusion 123 passes over the latch tooth 113, the protrusion 123 can automatically recover; in this way, it can be ensured that the setting of the protrusion 123 will not interfere with the sliding of the button 120.

[0078] Of course, in other embodiments, the protrusion 123 may also be elastically connected to the button 120 , for example, connected to the button 120 via an elastic rubber pad.

[0079] Alternatively, in other embodiments, the protrusion 123 can be rigidly connected to the buckle 122, and the protrusion 123 is made of a hard material. When the protrusion 123 abuts against the latch tooth 113, it can push the buckle 122 to deform, thereby ensuring that the protrusion 123 can pass over the latch tooth 113 abutting against it, thereby preventing the protrusion 123 from interfering with the sliding of the button 120.
