Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to a lighting fixture that allows for convenient adjustment of lighting effects. Background Technology

[0002] In some lighting fixtures such as streetlights, the existing lamp head is usually a single integral structure. At the same height, its illumination angle range is constant, the lighting effect is fixed, and the flexibility of use is low. People skilled in the art want a lighting fixture that can more easily adjust the lighting effect.

[0003] In addition, existing lamp holders are usually fixed in the horizontal direction. When the lighting position needs to be adjusted, it is often necessary to move the entire lamp, but moving the entire lamp may be laborious and troublesome. Summary of the Invention

[0004] The main objective of this invention is to provide a lamp that allows for easy adjustment of lighting effects, aiming to solve the technical problems of existing lamps where the lighting angle range of the lamp head is constant, the lighting effect is fixed, and the flexibility of use is low.

[0005] To achieve the above objectives, the present invention proposes a lighting fixture that facilitates adjustment of lighting effects, comprising a lamp post assembly and a lamp head assembly. The lamp post assembly includes a crossbar, and the lamp head assembly includes a lamp head base, a first swing assembly, and a second swing assembly. The lamp head base is connected to the crossbar. Both the first and second swing assemblies are rotatably connected to the lamp head base. The first and second swing assemblies are arranged horizontally, and the rotation axes of both the first and second swing assemblies extend in the front-back direction. A first light source assembly is provided on the first swing assembly, and a second light source assembly is provided on the second swing assembly. A swing drive mechanism is provided on the lamp head base, and the swing drive mechanism is drively connected to the first and second swing assemblies. The swing drive mechanism can drive the first and / or second swing assemblies to swing to change the included angle between the first and second light source assemblies.

[0006] The lamp head assembly includes a first swing component and a second swing component that can swing up and down. The first light source component and the second light source component are respectively disposed on the first swing component and the second swing component. The swing drive mechanism can drive and control the first swing component and / or the second swing component to swing to change the included angle between the first light source component and the second light source component, so that different illumination angles are formed between the first light source component and the second light source component, thereby changing the illumination range of the lamp head assembly and making it more flexible to use.

[0007] Preferably, the first swing assembly includes a first swing arm, and the second swing assembly includes a second swing arm. The first swing arm is provided with a first sliding groove that extends in the left-right direction, and the second swing arm is provided with a second sliding groove that extends in the left-right direction. The first sliding groove and the second sliding groove are arranged in a front-back arrangement, and the first sliding groove and the second sliding groove partially overlap in the left-right direction. The lamp head assembly also includes a transmission component and a transmission rod. The transmission component is connected to the swing drive mechanism, which can drive the transmission component to rotate. The rotation axis of the transmission component and the transmission rod both extend in the front-back direction. The transmission rod passes through the first slide groove and the second slide groove. The transmission rod is located in the left-right direction between the rotation axis of the first swing assembly and the lamp head base and the rotation axis of the second swing assembly and the lamp head base. The transmission rod can slide within the first slide groove and the second slide groove. A limiting seat is fixed on the lamp holder, and the limiting seat is provided with a limiting groove extending in the vertical direction. The transmission rod is slidably connected to the limiting groove. The transmission component is provided with an eccentric guide groove. The extension direction of the eccentric guide groove gradually moves away from the rotation axis of the transmission component in the radial direction of the transmission component. The transmission rod is slidably connected to the eccentric guide groove. The transmission rod can slide along the eccentric guide groove and slide up and down along the limiting groove when the transmission component rotates, so as to drive the first swing component and the second swing component to swing synchronously towards or away from each other.

[0008] The swing drive mechanism drives the transmission component to rotate, and the eccentric guide groove also rotates. Simultaneously, the limiting groove of the limiting seat restricts the left and right position of the transmission rod. The transmission rod slides along the eccentric guide groove, moving closer to or further away from the rotation axis of the transmission component, thus achieving up-and-down movement. Simultaneously, the transmission rod slides and rotates relative to each other within the first groove of the first swing arm and the second groove of the second swing arm, thereby driving the first and second swing arms to swing up and down synchronously. This solution, through a single swing drive mechanism and the cooperation of the transmission component, transmission rod, first groove, and second groove, can drive the first and second light source assemblies to swing synchronously towards or away from each other, exhibiting good synchronization, occupying less space, and having a compact structure.

[0009] Preferably, the lamp holder is an integrally extruded component extending in the front-back direction. The lamp holder has a first connecting strip and a second connecting strip extending in the front-back direction. The first connecting strip and the second connecting strip are arranged left and right. The first connecting strip has a first connecting hole, and the second connecting strip has a second connecting hole. The first connecting strip has a plurality of first clearance grooves, and the second connecting strip has a plurality of second clearance grooves. The first swing assembly further includes a first connector, which is fixedly connected to the first swing arm. The second swing assembly further includes a second connector, which is fixedly connected to the second swing arm. The first swing arm has a first through hole, and the second swing arm has a second through hole. The first connector includes a first connecting part, which has a third through hole. The second connector includes a second connecting part, which has a fourth through hole. The limiting seat has a fifth through hole and a sixth through hole arranged on the left and right sides. The left side of the limiting seat, the first connecting part, and the first swing arm are respectively disposed in a plurality of first clearance slots. The right side of the limiting seat, the second connecting part, and the second swing arm are respectively disposed in a plurality of second clearance slots. The lamp head assembly further includes a first connecting rod and a second connecting rod. The first connecting rod passes through the first connecting hole, the first through hole, the third through hole, and the fifth through hole. The second connecting rod passes through the second connecting hole, the second through hole, the fourth through hole, and the sixth through hole.

[0010] The lamp holder is an integrally extruded part. The lamp holder has a first connecting hole and a second connecting hole formed on it. A first clearance groove is machined on the first connecting strip, and a second clearance groove is machined on the second connecting strip. The first swing arm, the first connecting piece, and the limiting seat are connected to the lamp holder through the first connecting rod, and the second swing arm, the second connecting piece, and the limiting seat are connected to the lamp holder through the second connecting rod. This simplifies the processing and installation of each part and makes the structure more compact.

[0011] Preferably, the lamp head assembly further includes an elastic element capable of applying a downward elastic force to the transmission rod. The downward elastic force generated by the elastic element on the transmission rod can partially offset the gravity of the first and second swing assemblies located outside the base, reducing the driving force of the swing drive mechanism and helping to maintain the swing angle of the first and second light source assemblies.

[0012] Preferably, a slider is fixed on the transmission rod. The slider includes a middle sliding part, a front sliding part, and a rear sliding part. The middle sliding part is disposed in the limiting sliding groove. The front sliding part is disposed on the front side of the limiting seat, and the rear sliding part is disposed on the rear side of the limiting seat. The front sliding part is provided with at least two vertically arranged front pulleys, and the rear sliding part is provided with at least two vertically arranged rear pulleys. The axes of the front pulleys and the rear pulleys both extend in the left-right direction. The transmission rod is located between at least two of the front pulleys in the vertical direction, and the transmission rod is located between at least two of the rear pulleys in the vertical direction. The front pulleys abut against the front side of the limiting seat, and the rear pulleys abut against the rear side of the limiting seat.

[0013] The middle sliding part can limit the left and right position of the transmission rod within the limiting groove. The front and rear pulleys can roll on the front and rear sides of the limiting seat to limit the front and rear position of the slider. At least two front pulleys and at least two rear pulleys are on the upper and lower sides of the transmission rod to keep the transmission rod horizontal, reduce the up and down tilt of the transmission rod on the front and rear sides during the movement, and maintain normal transmission action.

[0014] Preferably, the elastic element is a compression spring, which is located between the upper side of the intermediate sliding part and the upper side of the limiting sliding groove. The compression spring can apply downward pressure to the slider. The compression spring generates downward pressure on the slider, and the structure is relatively compact and simple.

[0015] Preferably, a first torsion spring is provided between the lamp holder and the first swing assembly, and a second torsion spring is provided between the lamp holder and the second swing assembly. The first torsion spring is used to apply an upward rotational elastic force to the first swing assembly, and the second torsion spring is used to apply an upward rotational elastic force to the second swing assembly.

[0016] The first and second torsion springs can partially offset the gravity of the first and second light source components, thereby reducing the torque load on the overall structure, reducing the driving force of the swing drive mechanism, and helping to maintain the swing angle of the first and second light source components.

[0017] Preferably, the crossbar extends in the front-to-back direction, the crossbar has an inner cavity through which wires can pass, and the lower side of the crossbar has a long groove communicating with the inner cavity, the long groove extending in the front-to-back direction; The lower side of the crossbar is provided with a moving component, which includes a front and rear slide block and a rotating seat. The upper side of the front and rear slide blocks is provided with a sliding component. The front and rear slide blocks are slidably connected to the crossbar in the front-rear direction through the sliding component. The rotating seat is rotatably connected to the front and rear slide blocks. The rotation axis of the rotating seat is vertically arranged. The front and rear slide blocks are provided with a wire-passing hole. The upper side of the wire-passing hole extends into the inner cavity or is directly opposite the long slot. The lower side of the wire-passing hole communicates with the lower side of the rotating seat. The lamp holder is fixedly connected to the rotating seat.

[0018] The front and rear slides are slidably connected to the crossbar via a sliding assembly, allowing the slides to move relative to the crossbar in a forward or backward position. The lamp head assembly is mounted on the underside of the slides, enabling independent adjustment of its forward or backward position. A rotating base is rotatably connected to the slides, allowing adjustment of the lamp head assembly's lateral angle, making position adjustment more flexible. The lamp head assembly's wires pass through a wire hole from the bottom and extend upwards into the crossbar's inner cavity. As the slides and lamp head assembly move forward and backward, the crossbar's long slot allows the wires to follow, energizing the lamp head assembly. This luminaire allows adjustment of the lamp head assembly's forward / backward position and lateral angle, as well as the illumination angles of the first and second light source components within the lamp head assembly, without moving the entire luminaire. This makes adjusting the lamp head assembly's lighting effect more convenient and flexible, and the concealed wiring enhances its aesthetics.

[0019] Preferably, the sliding assembly includes a slider, the left and right width of which is greater than the width of the long groove. The slider is disposed in the inner cavity. A connecting pipe is provided between the slider and the front and rear sliding seats. The connecting pipe passes through the long groove. The wire hole is disposed in the connecting pipe. First pulleys are provided on both the left and right sides of the slider. The first pulleys abut against the bottom plate of the inner cavity. The axis of the first pulleys extends in the left and right direction.

[0020] The slider and the first pulley slide within the inner cavity of the crossbar. The connecting tube passes through the long groove to connect the slider and the front and rear slide blocks. The wire passes through the wire hole inside the connecting tube, which protects the wire.

[0021] Preferably, the rotating seat is provided with a mounting hole, and the front and rear sliding seats are disposed in the mounting hole and rotatably connected; The front and rear slide blocks include a first seat portion and a second seat portion located above the first seat portion. The diameter of the first seat portion is larger than the diameter of the second seat portion. An installation step is provided in the mounting hole. The diameter of the first seat portion is larger than the diameter of the inner hole of the installation step. The first seat portion is located below the installation step. The second seat portion is located inside the inner hole of the installation step. An installation countersunk hole is provided on the upper side of the installation step. The front and rear slide blocks are also provided with a third connecting hole that passes through the first seat portion and the second seat portion vertically. A first countersunk hole is provided on the lower side of the third connecting hole. A seventh through hole is provided on the sliding member. The sliding assembly further includes a support sleeve, a limiting plate, and a connecting nut. The diameter of the limiting plate is larger than the diameter of the inner hole of the mounting step. The limiting plate is disposed within the mounting countersunk hole and has an eighth through hole. The support sleeve is disposed on the upper side of the limiting plate. The connecting tube passes through the third connecting hole, the eighth through hole, the support sleeve, and the seventh through hole sequentially from bottom to top. A connecting protrusion is provided on the lower outer periphery of the connecting tube, and the connecting protrusion abuts against the lower side of the first countersunk hole. The connecting nut is disposed on the upper side of the sliding component, and a connecting thread is provided on the upper outer side of the connecting tube. The connecting nut is threadedly connected to the connecting thread.

[0022] Preferably, the lamp post assembly includes a fixed lamp post, a movable lamp post, and a lifting drive mechanism. The movable lamp post is slidably connected to the fixed lamp post in the vertical direction, and the lifting drive mechanism is drively connected to the movable lamp post. The lifting drive mechanism can drive the movable lamp post to move up and down relative to the fixed lamp post, and the crossbar is fixed to the upper side of the movable lamp post.

[0023] The lifting drive mechanism can move the movable lamp post up and down, thereby making it easy to adjust the height of the lamp head assembly to meet different lighting needs.

[0024] Preferably, the fixed light pole is sleeved on the outside of the movable light pole, and the lifting drive mechanism is located on the inside of the fixed light pole and the movable light pole. The lifting drive mechanism includes an electric push rod, the body of which is fixedly connected to the lower side of the fixed light pole, and the output rod of which is connected to the movable light pole. A pulley seat is fixedly connected to the lower side of the movable light pole, and a plurality of second pulleys are rotatably connected to the pulley seat. The outer periphery of the second pulleys abuts against the inner sidewall of the fixed light pole. The crossbar is located on the upper front side of the movable light pole. The pulley seat has second pulleys on both the front and rear sides, and the axis of the second pulleys extends in the left-right direction.

[0025] The electric push rod, movable light pole, and fixed light pole are nested from the inside out, which simplifies the structure and improves the aesthetics of the lighting fixture. Since the lamp head assembly is located on the upper front side of the movable light pole, its weight tends to cause the movable light pole to tilt forward, increasing friction between the movable and fixed light poles. Therefore, in this design, the movable light pole slides against the fixed light pole via multiple limiting pulleys, reducing friction and making the lifting process smoother and quieter.

[0026] Preferably, the lamp post assembly is provided with a magnetically attached electrical rail, and the lamp further includes a magnetically attached lamp head, which is magnetically fixed and electrically connected to the magnetically attached electrical rail. The magnetically attached lamp head can be installed on the magnetically attached electrical rail of the lamp post assembly, which facilitates improved lighting effect. Attached Figure Description

[0032] like Figures 1 to 15 As shown, a lamp fixture that facilitates adjustment of lighting effects includes a lamp post assembly 1 and a lamp head assembly 7. The lamp post assembly 1 includes a crossbar 13, and the lamp head assembly 7 includes a lamp head base 71, a first swing assembly 73, and a second swing assembly 74. The lamp head base 71 is connected to the crossbar 13. The first swing assembly 73 and the second swing assembly 74 are both rotatably connected to the lamp head base 71. The first swing assembly 73 and the second swing assembly 74 are arranged left and right. The rotation axis of the first swing assembly 73 and the rotation axis of the second swing assembly 74 both extend in the front-back direction. A first light source assembly 78 is provided on the first swing assembly 73, and a second light source assembly 79 is provided on the second swing assembly 74. The first light source assembly 78 and the second light source assembly 79 can emit light downwards. A swing drive mechanism 72 is provided on the lamp head base 71. The swing drive mechanism 72 is connected to the first swing assembly 73 and the second swing assembly 74. The swing drive mechanism 72 can drive the first swing assembly 73 and / or the second swing assembly 74 to swing to change the included angle between the first light source assembly 78 and the second light source assembly 79. The swing drive mechanism 72 can be a swing drive motor. A cover can be provided on the upper side of the lamp holder 71 to cover the swing drive motor and other components. The swing drive mechanism 72 can also be a manual drive mechanism such as a handwheel.

[0033] The lamp head assembly 7 includes a first swing assembly 73 and a second swing assembly 74 that can swing up and down. A first light source assembly 78 and a second light source assembly 79 are respectively disposed on the first swing assembly 73 and the second swing assembly 74. The swing drive mechanism 72 can drive and control the first swing assembly 73 and / or the second swing assembly 74 to swing, thereby changing the included angle between the first light source assembly 78 and the second light source assembly 79, so that different illumination angles are formed between the first light source assembly 78 and the second light source assembly 79, thereby changing the illumination range of the lamp head assembly 7 and making it more flexible to use.

[0034] In some specific embodiments, reference is made to Figures 2 to 9The first swing assembly 73 includes a first swing arm 731, and the second swing assembly 74 includes a second swing arm 741. The first swing arm 731 is provided with a first sliding groove 7311, which extends in the left-right direction. The second swing arm 741 is provided with a second sliding groove 7411, which extends in the left-right direction. The first sliding groove 7311 and the second sliding groove 7411 are arranged in a front-back arrangement, and the first sliding groove 7311 and the second sliding groove 7411 partially overlap in the left-right direction. The lamp head assembly 7 also includes a transmission component 75 and a transmission rod 76. The transmission component 75 is connected to the swing drive motor. The transmission component 75 can be directly fixed and coaxially arranged with the rotating shaft of the swing drive motor. The swing drive motor can drive the transmission component 75 to rotate. The rotation axis of the transmission component 75 and the transmission rod 76 both extend in the front-back direction. The transmission rod 76 passes through the first slide groove 7311 and the second slide groove 7411. The transmission rod 76 is located in the left-right direction between the rotation axis of the first swing assembly 73 and the lamp head seat 71 and the rotation axis of the second swing assembly 74 and the lamp head seat 71. The transmission rod 76 can slide in the first slide groove 7311 and the second slide groove 7411. A limiting seat 77 is fixed on the lamp holder 71. The limiting seat 77 is provided with a limiting groove 771 extending in the vertical direction. The transmission rod 76 is slidably connected to the limiting groove 771. The transmission member 75 is provided with an eccentric guide groove 751. The extension direction of the eccentric guide groove 751 gradually moves away from the rotation axis of the transmission member 75 in the radial direction of the transmission member 75. The transmission rod 76 is slidably connected to the eccentric guide groove 751. The transmission rod 76 can slide along the eccentric guide groove 751 and slide up and down along the limiting groove 771 when the transmission member 75 rotates, so as to drive the first swing assembly 73 and the second swing assembly 74 to swing synchronously towards or away from each other.

[0035] The swing drive mechanism 72 drives the transmission component 75 to rotate, and the eccentric guide groove 751 also rotates. Simultaneously, the limiting groove 771 of the limiting seat 77 restricts the left and right positions of the transmission rod 76. The transmission rod 76 slides along the eccentric guide groove 751, moving closer to or further away from the rotation axis of the transmission component 75 to achieve up-and-down movement. At the same time, the transmission rod 76 slides and rotates relative to the first groove 7311 of the first swing arm 731 and the second groove 7411 of the second swing arm 741, thereby driving the first swing arm 731 and the second swing arm 741 to swing up and down synchronously. This solution, through a single swing drive motor and the cooperation of the transmission component 75, the transmission rod 76, the first groove 7311, and the second groove 7411, can drive the first light source assembly 78 and the second light source assembly 79 to swing synchronously towards or away from each other, exhibiting good synchronization, occupying less space, and having a compact structure. Furthermore, the lengths of the first groove 7311 and the second groove 7411 in this structure do not need to be very long, making the structure even more compact. In other embodiments, the first swing arm 731 and the second swing arm 741 may also be driven synchronously by a structure such as a gear assembly.

[0036] Furthermore, referring to Figure 9 The eccentric guide groove 751 includes two semi-guide grooves 7511 connected end-to-end. The two semi-guide grooves 7511 are located on opposite sides of the rotation axis of the transmission member 75, and at least partially move radially away from the rotation axis of the transmission member 75. The two semi-guide grooves 7511 are connected end-to-end, allowing the oscillating drive motor to rotate continuously in one direction, preventing damage to the oscillating drive motor due to the end position failing to rotate. Preferably, the two semi-guide grooves 7511 are mirror-symmetrically arranged. In other embodiments, the transmission rod 76 is fixed to the transmission member 75 and can move circumferentially with the transmission member 75. The circumferential movement of the transmission rod 76 with the transmission member 75 also enables the up-and-down movement of the transmission rod 76.

[0037] Furthermore, there are two limiting seats 77, arranged one behind the other. The first swing arm 731 and the second swing arm 741 are both located between the two limiting seats 77. The front and rear sides of the transmission rod 76 are slidably connected to the limiting grooves 771 of the two limiting seats 77, respectively. The transmission component 75 is located on the front side of the front limiting seat 77, and the swing drive motor is located on the front side of the transmission component 75. The arrangement of the first swing arm 731 and the second swing arm 741 between the two limiting seats 77, and the slidable connection of the front and rear sides of the transmission rod 76 to the limiting grooves 771 of the two limiting seats 77, improves structural stability.

The second connecting rod 714 passes through a second connecting hole 7121, a second through hole 7412, a fourth through hole and a sixth through hole 773.

[0039] The lamp holder 71 is an integrally extruded part. The lamp holder 71 has a first connecting hole 7111 and a second connecting hole 7121 formed on it. Several first clearance grooves 7112 are machined on the first connecting strip 711, and several second clearance grooves 7122 are machined on the second connecting strip 712. The first swing arm 731, the first connecting member 732 and the limiting seat 77 are connected to the lamp holder 71 by the first connecting rod 713. The second swing arm 741, the second connecting member 742 and the limiting seat 77 are connected to the lamp holder 71 by the second connecting rod 714. The first clearance grooves 7112 can also fix the front and rear positions of the first swing arm 731, the first connecting member 732 and the limiting seat 77. The second clearance grooves 7122 can also fix the front and rear positions of the second swing arm 741, the second connecting member 742 and the limiting seat 77. This simplifies the processing and installation of each part and makes the structure more compact. Furthermore, the base of the swing drive motor can also be fixed to the lamp holder 71 via the first connecting rod 713 and the second connecting rod 714.

[0040] In some specific embodiments, reference is made to Figure 7 The lamp head assembly 7 also includes an elastic element that can apply a downward elastic force to the transmission rod 76. The downward elastic force generated by the elastic element on the transmission rod 76 can partially offset the gravity of the first swing assembly 73 and the second swing assembly 74 located outside the base, reduce the driving force of the swing drive mechanism 72, and help maintain the swing angle of the first light source assembly 78 and the second light source assembly 79.

[0041] Furthermore, referring to Figure 7 and Figure 8 A slider 761 is fixed on the transmission rod 76. The slider 761 includes a middle sliding part 7611, a front sliding part 7612, and a rear sliding part 7613. The middle sliding part 7611 is located in the limiting sliding groove 771. The front sliding part 7612 is located on the front side of the limiting seat 77, and the rear sliding part 7613 is located on the rear side of the limiting seat 77. The front sliding part 7612 is provided with at least two vertically arranged front pulleys 7614, and the rear sliding part 7613 is provided with at least two vertically arranged rear pulleys 7615. The axes of the front pulleys 7614 and the rear pulleys 7615 both extend in the left-right direction. The transmission rod 76 is located between at least two front pulleys 7614 in the vertical direction and between at least two rear pulleys 7615 in the vertical direction. The front pulleys 7614 abut against the front side of the limiting seat 77, and the rear pulleys 7615 abut against the rear side of the limiting seat 77.

[0042] The intermediate sliding part 7611 can limit the left and right position of the transmission rod 76 within the limiting sliding groove 771. The front pulley 7614 and the rear pulley 7615 can roll on the front and rear sides of the limiting seat 77 to limit the front and rear position of the slider 761. At least two front pulleys 7614 and at least two rear pulleys 7615 are on the upper and lower sides of the transmission rod 76 to keep the transmission rod 76 horizontal, reduce the up and down tilt of the transmission rod 76 on the front and rear sides during the movement, and maintain normal transmission action.

[0043] Furthermore, the elastic element is a compression spring 762, which is located between the upper side of the intermediate sliding portion 7611 and the upper side of the limiting sliding groove 771. The compression spring 762 can apply downward pressure to the slider 761. The compression spring 762 generates downward pressure on the slider 761, resulting in a more compact and simple structure. In other embodiments, the elastic element can also be a tension spring, which is connected between the lower side of the slider 761 and the lamp holder 71, and applies a downward pulling force to the slider 761.

[0044] In some specific embodiments, reference is made to Figure 3 A first torsion spring 715 is provided between the lamp holder 71 and the first swing assembly 73, and a second torsion spring is provided between the lamp holder 71 and the second swing assembly 74. The first torsion spring 715 is used to apply an upward rotational elastic force to the first swing assembly 73, and the second torsion spring is used to apply an upward rotational elastic force to the second swing assembly 74.

[0045] The first torsion spring 715 and the second torsion spring can partially offset the gravity of the first light source assembly 78 and the second light source assembly 79 on the outside of the lamp holder 71, thereby reducing the torque load on the overall structure and the driving force of the swing drive mechanism 72, which is beneficial to maintaining the swing angle of the first light source assembly 78 and the second light source assembly 79. Preferably, the first torsion spring 715 can be sleeved on the first connecting rod 713, and the second torsion spring can be sleeved on the second connecting rod 714 for easy installation.

[0046] In some specific embodiments, reference is made to Figures 10 to 13 The crossbar 13 extends in the front-to-back direction. The crossbar 13 has an inner cavity through which wires can pass. The lower side of the crossbar 13 has a long groove 131 that communicates with the inner cavity. The long groove 131 extends in the front-to-back direction. A movable component is provided on the lower side of the crossbar 13. The movable component includes a front and rear slide block 2 and a rotating seat 3. A sliding component is provided on the upper side of the front and rear slide blocks 2. The front and rear slide blocks 2 are slidably connected to the crossbar 13 in the front and rear direction through the sliding component. The rotating seat 3 is rotatably connected to the front and rear slide blocks 2. The rotation axis of the rotating seat 3 is set vertically. A wire hole 421 is provided on the front and rear slide blocks 2. The upper side of the wire hole 421 extends into the inner cavity or is directly opposite the long groove 131. The lower side of the wire hole 421 is connected to the lower side of the rotating seat 3. The lamp holder 71 is fixedly connected to the rotating seat 3.

[0047] The front and rear slide blocks 2 are slidably connected to the crossbar 13 via a sliding assembly, allowing the front and rear slide blocks 2 to move relative to the crossbar 13. The lamp head assembly 7 is mounted on the underside of the front and rear slide blocks 2, thus allowing the front and rear position of the lamp head assembly 7 to be adjusted independently. The rotating seat 3 is rotatably connected to the front and rear slide blocks 2, allowing the lateral angle of the lamp head assembly 7 to be adjusted rotatably, making the position adjustment of the lamp head assembly 7 more flexible. The wires of the lamp head assembly 7 can pass through the wire hole 421 from the bottom and extend upward into the inner cavity of the crossbar 13. When the front and rear slide blocks 2 and the lamp head assembly 7 move back and forth, the long slot 131 of the crossbar 13 allows the wires to move along with them, enabling the lamp head assembly 7 to be powered.

[0048] This lamp can adjust the front-to-back position and lateral angle of the lamp head assembly 7, as well as the illumination angle of the first light source assembly 78 and the second light source assembly 79 in the lamp head assembly 7, without moving the entire lamp. Adjusting the lighting effect of the lamp head assembly 7 is more convenient and flexible, and the wires are hidden inside for a more aesthetically pleasing look.

[0049] Furthermore, the sliding assembly includes a slider 41, the left and right width of which is greater than the width of the long groove 131. The slider 41 is disposed in the inner cavity. A connecting pipe 42 is provided between the slider 41 and the front and rear slide blocks 2. The connecting pipe 42 passes through the long groove 131. A wire hole 421 is disposed in the connecting pipe 42. A first pulley 43 is provided on both the left and right sides of the slider 41. The first pulley 43 abuts against the bottom plate of the inner cavity. The axis of the first pulley 43 extends in the left and right direction.

[0050] The slider 41 and the first pulley 43 slide within the inner cavity of the crossbar 13. The connecting tube 42 passes through the long groove 131 to connect the slider 41 and the front and rear slide blocks 2. The wire passes through the wire hole 421 inside the connecting tube 42, and the connecting tube 42 can protect the wire.

[0051] Furthermore, referring to Figure 12 The rotating seat 3 is provided with a mounting hole 31, and the front and rear sliding seats 2 are located in the mounting hole 31 and are rotatably connected. The front and rear slide block 2 includes a first seat portion 21 and a second seat portion 22 located on the upper side of the first seat portion 21. The diameter of the first seat portion 21 is larger than the diameter of the second seat portion 22. The mounting hole 31 is provided with a mounting step 311. The diameter of the first seat portion 21 is larger than the diameter of the inner hole of the mounting step 311. The first seat portion 21 is located on the lower side of the mounting step 311. The second seat portion 22 is located in the inner hole of the mounting step 311. The upper side of the mounting step 311 is provided with a mounting countersunk hole 312. The front and rear slide block 2 is also provided with a third connecting hole 23 that passes through the first seat portion 21 and the second seat portion 22 vertically. The lower side of the third connecting hole 23 is provided with a first countersunk hole. The sliding member 41 is provided with a seventh through hole 411. The sliding assembly also includes a support sleeve 44, a limiting plate 45, and a connecting nut 46. The diameter of the limiting plate 45 is larger than the diameter of the inner hole of the mounting step 311. The limiting plate 45 is located inside the mounting countersunk hole 312. The limiting plate 45 has an eighth through hole 451. The support sleeve 44 is located on the upper side of the limiting plate 45. The connecting pipe 42 passes through the third connecting hole 23, the eighth through hole 451, the support sleeve 44, and the seventh through hole 411 from bottom to top. The lower outer periphery of the connecting pipe 42 has a connecting protrusion ring 422, which abuts against the lower side of the first countersunk hole. The connecting nut 46 is located on the upper side of the sliding member 41. The upper outer side of the connecting pipe 42 has a connecting thread, and the connecting nut 46 is threadedly connected to the connecting thread.

[0052] The front and rear slide blocks 2 are located in the mounting holes 31 of the rotating seat 3. The rotating seat 3 rotates around the front and rear slide blocks 2, so the wires of the lamp head assembly 7 are connected to the lamp head assembly 7 in the rotation center area of ​​the lamp head assembly 7, reducing the possibility of wire damage. When assembling the rotating seat 3, the front and rear slide blocks 2 and the sliding assembly, the connecting tube 42 passes through the third connecting hole 23, the eighth through hole 451, the support sleeve 44 and the seventh through hole 411 from bottom to top. The support sleeve 44 separates the limiting plate 45 and the sliding member 41. The support sleeve 44 is in the long groove 131 and is connected to the connecting tube 42 with the connecting nut 46. The connection of each component by the connecting nut 46 and the connecting tube 42 simplifies the assembly steps.

[0053] Furthermore, a first rotation limiting part 313 is provided in the mounting hole 31, and a second rotation limiting part is provided on the front and rear slide blocks 2. The first rotation limiting part 313 and the second rotation limiting part are matched in position, and the first rotation limiting part 313 and the second rotation limiting part can limit the rotation angle of the rotating seat 3.

[0054] The rotating seat 3 rotates around the front and rear sliding seats 2 to adjust the angle. When the first rotation limit part 313 touches the second rotation limit part, the rotating seat 3 cannot continue to rotate, which can limit the rotation range of the rotating seat 3 and the lamp holder to prevent the wire from being damaged by excessive rotation angle. Furthermore, the outer part of the connecting tube 42 protrudes from the outer periphery of the second seat part 22. The protruding part of the connecting tube 42 is the second rotation limit part. The mounting step 311 is provided with a rotation limit groove. The two circumferential sides of the rotation limit groove are the first rotation limit parts 313. The protruding part of the connecting tube 42 moves within the rotation limit groove, so as to achieve the limiting cooperation of the first rotation limit part 313 and the second rotation limit part.

[0055] Furthermore, the circumferential sidewalls of the front and rear slide blocks 2 are provided with second spring top beads 26, and the inner sidewalls of the mounting holes 31 are provided with second grooves 32. The second spring top beads 26 are matched with the second grooves 32, and the second spring top beads 26 can enter the corresponding second grooves 32.

[0056] The second groove 32 rotates with the rotating seat 3. When the second groove 32 rotates to be directly opposite the second spring top bead 26, the second spring top bead 26 enters the second groove 32 to indicate the position and play a certain positioning role.

[0057] In some specific embodiments, the upper side of the front and rear slide blocks 2 is provided with a first spring top ball 25, and the lower side of the crossbar 13 is provided with a plurality of first grooves 132. The plurality of first grooves 132 are arranged at intervals along the front and rear direction. The first spring top ball 25 is matched with the plurality of first grooves 132, and the first spring top ball 25 can enter the corresponding first groove 132.

[0058] The first spring ball 25 moves back and forth with the front and rear slide blocks 2. When the first spring ball 25 moves to face a certain first groove 132, the first spring ball 25 enters the first groove 132 and plays a certain positioning role. Multiple first grooves 132 can position multiple different positions.

[0059] In some specific embodiments, reference is made to Figure 14 The lamp post assembly 1 includes a fixed lamp post 11, a movable lamp post 12, and a lifting drive mechanism 14. The fixed lamp post 11 can be fixed in place. The movable lamp post 12 is slidably connected to the fixed lamp post 11 in the vertical direction. The lifting drive mechanism 14 is connected to the movable lamp post 12 in a transmission manner. The lifting drive mechanism 14 can drive the movable lamp post 12 to move up and down relative to the fixed lamp post 11. The crossbar 13 is fixed to the upper side of the movable lamp post 12.

[0060] The lifting drive mechanism 14 can drive the movable lamp post 12 to move up and down, thereby easily adjusting the height of the lamp head assembly 7 to meet different lighting needs. For example, in some lamps, when the lamp head is raised higher, it can be used as a street lamp, illuminating the desk and the room at the same time; when the lamp head is lowered, it can be lowered below the line of sight, avoiding vertical illumination of the light source into the eyes. At this time, the system is equivalent to a desk lamp, and the light can be concentrated on the desk as much as possible, making it convenient for use after dark.

[0061] Furthermore, the fixed light pole 11 is sleeved on the outside of the movable light pole 12, and the lifting drive mechanism 14 is located on the inside of the fixed light pole 11 and the movable light pole 12. The lifting drive mechanism 14 includes an electric push rod. The body of the electric push rod is fixedly connected to the lower side of the fixed light pole 11, and the output rod of the electric push rod is connected to the movable light pole 12. A pulley seat 15 is fixedly connected to the lower side of the movable light pole 12. A plurality of second pulleys 16 are rotatably connected on the pulley seat 15. The outer periphery of the second pulleys 16 abuts against the inner sidewall of the fixed light pole 11. A crossbar 13 is located on the upper front side of the movable light pole 12. The pulley seat 15 is provided with second pulleys 16 on both the front and rear sides. The axis of the second pulleys 16 extends in the left and right direction.

[0062] The electric push rod, movable lamp post 12, and fixed lamp post 11 are nested from the inside out, which simplifies the structure and improves the aesthetics of the lamp. Since the lamp head assembly 7 is located on the upper front side of the movable lamp post 12, its weight tends to cause the movable lamp post 12 to tilt forward, increasing friction between it and the fixed lamp post 11. Therefore, in this design, the movable lamp post 12 slides against the fixed lamp post 11 via multiple limiting pulleys, reducing friction and making the lifting process smoother and quieter. The electric push rod can be controlled by a control panel or buttons, and these control elements can be located on the fixed lamp post 11.

[0063] Furthermore, a light strip 6 is provided on the side of the fixed light pole 11 near the crossbar 13. The light strip 6 installed on the fixed light pole 11 can serve a lighting or decorative purpose.

[0064] In some specific embodiments, reference is made to Figure 15 The lamp post assembly 1 is equipped with a magnetic electrical connection rail, and the lamp also includes a magnetic lamp head. The magnetic lamp head is magnetically fixed and electrically connected to the magnetic electrical connection rail. The magnetic electrical connection rail contains a conductive sheet 17 and an iron strip 18. The magnetic lamp head is equipped with a receiving part and a magnet. The iron strip 18 can be magnetically fixed to the magnet. The conductive sheet 17 abuts against the receiving part to conduct electricity. The magnetic lamp head can be installed on the magnetic electrical connection rail of the lamp post assembly 1 to improve the lighting effect.
