Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a lamp body unit, a lamp provided with the lamp body unit, and a lighting system provided with the lamp. Background Art

[0002] With the rise and popularity of non-main light design, lamps such as downlights, spotlights, track lights, and line lights are favored by consumers. Figures 1 to 3 As shown, the spotlight 9 includes an outer ring seat 91, a fixed seat 92, a rotating seat 93, a lamp body 94, a light source 95, an optical element 96, etc.; the outer ring seat 91 is sleeved on the fixed seat 92, the fixed seat 92 has a receiving position 921, and the rotating seat 93 is located in the receiving position 921. The outer ring seat 91, the fixed seat 92 and the rotating seat 93 are connected by bolts 97, so that the outer ring seat 91 is fixedly connected to the fixed seat 92 by the bolts 97, and the rotating seat 93 can rotate relative to the fixed seat 92 and the outer ring seat 91 by the bolts 97. The lamp body 94 is installed on the rotating seat 93 to follow the rotating seat 93 to rotate relative to the fixed seat 92 and the outer ring seat 91, the light source 95 is installed in the lamp body 94, the optical element 96 is installed on the lamp body 94 and / or the rotating seat 93, and the light source 95 is set toward the optical element 96; through the above design, the rotating seat 93, the lamp body 94, the light source 95 and the optical element 96 can be rotated relative to the fixed seat 92 and the outer ring seat 91 through the bolts 97, so that the lighting angle of the light source 95 can be adjusted to meet the different lighting needs of users.

[0003] However, the existing spotlight 9 has the following shortcomings: the lamp body 94 is usually made of aluminum alloy material, which makes the lamp body 94 heavy. Therefore, when the lamp body 94 is installed on the rotating seat 93, the bolt 97 needs to bear a large force, but because the bolt 97 connecting the rotating seat 93 and the fixing ring is small, the load-bearing capacity of the bolt 97 is poor and it is easy to break; in addition, since the bolt 97 is fixedly connected to the rotating seat 93, the bolt 97 will rotate with the rotating seat 93 relative to the fixed seat 92 and the outer ring seat 91, which will cause the thread on the bolt 97 to wear the fixed seat 92, the outer ring seat 91, etc., thereby causing the rotating seat 93 to shake during the rotation relative to the fixed seat 92, and reducing the stability of the rotating seat 93 after the angle adjustment is completed. Summary of the invention

[0004] In order to solve the above problems, the main purpose of the utility model is to provide a lamp body unit with good adjustment stability and smooth adjustment rotation.

[0005] Another object of the utility model is to provide a lamp equipped with the lamp body unit.

[0006] Another object of the utility model is to provide a lighting system equipped with the above-mentioned lamp.

[0007] In order to achieve the main purpose of the utility model, the utility model provides a lamp body unit, including a fixed seat and a rotating seat, the fixed seat has a first accommodating position, the rotating seat is arranged in the first accommodating position, wherein the fixed seat is provided with two bearing holes, the two bearing holes are distributed on the opposite sides of the first accommodating position along its own axial direction, the bearing holes pass through the wall of the fixed seat and are connected with the first accommodating position, the rotating seat is provided with two connecting columns, the two connecting columns are matched one by one with the two bearing holes, the lamp body unit also includes two bearings, the two bearings are matched one by one with the two bearing holes, the outer ring of the bearing is interference fit with a corresponding bearing hole, and the inner ring of the bearing is fixedly sleeved on a corresponding connecting column.

[0008] As can be seen from the above, by arranging a bearing hole on the fixed seat, arranging a connecting column on the rotating seat and arranging a bearing to replace the existing use of bolts to connect the fixed seat and the rotating seat, the rotating seat can drive other components such as the lamp body to rotate relative to the fixed seat more smoothly, and the bearing has the advantage of strong load-bearing capacity, so it can be better suitable for lamp bodies made of aluminum alloy or other metals and alloys; at the same time, it can also avoid the fixed seat and other related parts from being worn when the rotating seat drives the lamp body and other components to rotate relative to the fixed seat, thereby extending the service life of the lamp body unit; furthermore, the above design is also conducive to ensuring the coaxiality of the rotating axis on both sides of the rotating seat.

[0009] A preferred solution is that the bearing hole is a stepped hole having a first hole segment and a second hole segment, the first hole segment is located between the second hole segment and the first accommodating position, the first hole segment is connected to the bearing, and the diameter of the first hole segment is smaller than the diameter of the second hole segment.

[0010] As can be seen from the above, this design is conducive to the assembly between the fixed seat, the rotating seat and the bearing, making the assembly between the fixed seat, the rotating seat and the bearing simpler and more convenient.

[0011] Another preferred solution is that the bearing is a plastic bearing, a carbon steel bearing or a stainless steel bearing.

[0012] As can be seen from the above, the use of plastic bearings is beneficial to reducing production costs and making the lamp body unit lightweight. Plastic bearings have a self-lubricating function, which can ensure that the rotating seat can always rotate smoothly relative to the fixed seat. The use of carbon steel bearings or stainless steel bearings can improve the wear resistance of the bearings, thereby extending the service life of the lamp body unit and making the cost of the lamp body unit relatively low.

[0013] A further solution is that the lamp body unit further comprises a lamp body and a damping member, the lamp body is mounted on the rotating seat, and the damping member can hinder the lamp body or the rotating seat from rotating.

[0014] As can be seen from the above, since the bearing can maximize the smoothness of the rotation of the rotating seat relative to the fixed seat, a damping member is provided to apply a certain damping to the lamp body or the rotating seat to ensure that the rotating seat and the lamp body and other components thereon can stably stay in the adjusted position.

[0015] A further solution is that the fixing seat has two protrusions and a first limiting portion, the two protrusions correspond one-to-one to the two bearing holes, in the height direction of the fixing seat, one protrusion is located directly above a corresponding bearing hole, the top of the protrusion has a convex arc surface, an avoidance position is formed between the first sides of the two protrusions, and the first limiting portion is connected between the second sides of the two protrusions; the lamp body is formed with a concave arc surface at the protrusion, the concave arc surface is arranged to match the convex arc surface, and the lamp body is formed with a second limiting portion at the first limiting portion, and the second limiting portion can be adjacent to the first limiting portion.

[0016] As can be seen from the above, the design of the raised portion is more conducive to forming an avoidance position, so that the rotating seat and the lamp body and other components thereon have a larger rotation adjustment range, and is conducive to the lightweight design of the fixed seat; and the coordinated design of the first limiting portion on the fixed seat and the second limiting portion on the lamp body is conducive to limiting the rotating seat to the direct illumination position, so that the lamp equipped with this lamp body unit can perform vertical illumination; and the design of the convex arc surface on the raised portion and the concave arc surface on the lamp body is conducive to assisting the rotating seat, lamp body and other components to rotate relative to the fixed seat, and has a certain limiting and guiding effect.

[0017] A further solution is that the damping member is installed at the top of the raised portion, the damping member passes through the convex arc surface and is adjacent to the concave arc surface, or the damping member is installed on the raised portion, the damping member passes through the inner side surface of the raised portion and is adjacent to the rotating seat; the damping member is a first spring plunger or an elastic rubber plug.

[0018] As can be seen from the above, due to the large weight of the lamp body, it is easy to apply torque to the rotating seat when the lamp body is in a tilted state, causing the rotating seat to rotate. Therefore, by arranging the damping member on the top of the protrusion and applying damping to the lamp body, it is possible to better prevent the adjusted rotating seat and the lamp body and other components thereon from rotating relative to the fixed seat, so that the rotating seat and the lamp body and other components thereon can be stabilized in the adjusted position; of course, arranging the damping member on the protrusion and applying damping to the rotating member can also stabilize the rotating seat and the lamp body and other components thereon in the adjusted position.

[0019] A further solution is that the lamp body unit also includes an outer ring seat, the outer ring seat has a second accommodating position, and the outer ring seat is provided with a first snap-fit ​​structure in the second accommodating position; the fixed seat is arranged in the second accommodating position, and the fixed seat is provided with a second snap-fit ​​structure, and the second snap-fit ​​structure is snap-fitted and connected with the first snap-fit ​​structure.

[0020] As can be seen from the above, the outer ring seat can be used to connect the lamp body unit with an external structure (such as a suspended ceiling, a plate, etc.), and by designing the connection structure between the outer ring seat and the fixed seat, the assembly between the outer ring seat and the fixed seat does not require the use of fasteners (such as bolts), thereby simplifying the assembly steps between the outer ring seat and the fixed seat, reducing the difficulty of assembly between the outer ring seat and the fixed seat, and improving the overall aesthetics of the lamp body unit.

[0021] A further solution is that the first locking structure is an annular locking groove, the second locking structure includes a plurality of second spring plungers, and the positioning beads of the second spring plungers are locked in the annular locking groove; the lamp body unit also includes an optical ring, a first locking portion is provided on the optical ring, and a second locking portion is provided on the fixing seat, and the second locking portion is locked and connected with the first locking portion; at least a portion of the optical ring is located in the first accommodating position, and the optical ring is also located in the second accommodating position.

[0022] It can be seen from the above that, through the design of the first snap-fit ​​structure and the second snap-fit ​​structure, the assembly between the outer ring seat and the fixed seat is simpler and more convenient, and the overall aesthetics of the lamp body unit can be improved; and the setting of the optical ring can improve the lighting effect of the light source of the lamp equipped with the lamp body unit, and the connection structure design between the optical ring and the fixed seat can make the assembly between the two more convenient and easy to operate, and can improve the overall aesthetics of the lamp body unit.

[0023] In order to achieve another purpose of the utility model, the utility model provides a lamp, which further includes the above-mentioned lamp body unit.

[0024] As can be seen from the above, the lamp equipped with the above-mentioned lamp body unit, its rotating seat, lamp body and other components can be smoothly rotated and adjusted relative to the fixed seat. At the same time, the rotating seat, lamp body and other components have good stability after adjustment and are not prone to position displacement after adjustment. The lamp also has the advantage of a long service life.

[0025] In order to achieve another purpose of the utility model, the utility model provides a lighting system, including a control terminal, wherein the lighting system also includes the above-mentioned lamp; the control terminal is electrically connected to the lamp, and / or the control terminal and the lamp exchange information.

[0026] As can be seen from the above, by arranging the above-mentioned lamps, the lighting system can smoothly rotate the rotating seat, lamp body and other components of the lamp when the rotating seat, lamp body and other components are rotated and adjusted relative to the fixed seat, while ensuring the stability of the rotating seat, lamp body and other components after adjustment, so that the rotating seat, lamp body and other components after adjustment are not easily positionally shifted, and the lamp has a long service life, which is beneficial to reducing the use cost of the lighting system.

[0037] Lamp Example

[0038] Reference Figures 4 to 6 The lamp 100 includes a lamp body unit 101, a light source 102 and an optical ring 7. The lamp body unit 101 includes a fixed seat 1, a rotating seat 2, a bearing 3, a lamp body 4, a damping member 5, an outer ring seat 6 and an optical ring 7.

[0039] Combination Figure 7 The fixing seat 1 has a first accommodation position 11, and the first accommodation position 11 penetrates the fixing seat 1 in the height direction of the fixing seat 1. In addition, two bearing holes 12 are provided on the fixing seat 1, and the two bearing holes 12 are distributed on opposite sides of the first accommodation position 11 along the axial direction of the bearing holes 12, and the bearing holes 12 penetrate the wall of the fixing seat 1 and communicate with the first accommodation position 11.

[0040] Combination Figure 8The rotating seat 2 is arranged in the first accommodation position 11 of the fixed seat 1, and two connecting columns 21 are arranged on the rotating seat 2. The two connecting columns 21 correspond to the two bearing 3 holes 12 on the fixed seat 1 one by one, and the connecting columns 21 are distributed along the axial direction of the bearing 3 holes 12. There are two bearings 3, and the two bearings 3 correspond to the two bearing 3 holes 12 one by one, and the outer ring of the bearing 3 is interference fit with the corresponding bearing 3 hole 12, and the inner ring of the bearing 3 is fixedly sleeved on a corresponding connecting column 21, so that the inner ring of the bearing 3 and the connecting column 21 are interference fit.

[0041] By using the bearing 3 to connect the bearing 3 hole 12 of the fixed seat 1 and the connecting column 21 of the rotating seat 2, the existing method of connecting the fixed seat 1 and the rotating seat 2 with bolts is replaced, so that when the rotating seat 2 drives the lamp body 4, the light source 102, the optical ring 7 and other parts arranged on other parts to rotate relative to the fixed seat 1, it can be smoother, and the bearing 3 has the advantage of strong load-bearing capacity, so it can be better applied to the lamp body 4 made of aluminum alloy or other metals and alloys. In addition, the setting of the bearing 3 can also prevent the fixed seat 1 from being worn when the rotating seat 2 drives the lamp body 4 and other parts to rotate relative to the fixed seat 1, thereby extending the service life of the lamp body unit 101. Furthermore, the above design is also conducive to ensuring the coaxiality of the rotation axis on both sides of the rotating seat 2.

[0042] In order to facilitate the assembly between the fixed seat 1, the rotating seat 2 and the bearing 3, the bearing 3 hole 12 is set as a stepped hole. The stepped hole has a first hole section 121 and a second hole section 122. The first hole section 121 is located between the second hole section 122 and the first accommodation position 11. The first hole section 121 is connected to the bearing 3, and the diameter of the first hole section 121 is smaller than the diameter of the second hole section 122. This design can make the assembly between the fixed seat 1, the rotating seat 2 and the bearing 3 simpler and more convenient.

[0043] In addition, the bearing 3 can preferably be a plastic bearing, which is conducive to reducing production costs and realizing a lightweight design of the lamp body unit 101. At the same time, since the plastic bearing has a self-lubricating function, it can also ensure that the rotating seat 2 can always rotate smoothly relative to the fixed seat 1. Of course, as another optional solution, the bearing 3 can also be a carbon steel bearing or a stainless steel bearing to better improve the wear resistance of the bearing 3, thereby further extending the service life of the lamp body unit 101; and the cost of carbon steel bearings or stainless steel bearings is relatively low, thereby also achieving the purpose of saving the production cost of the lamp 100.

[0044] The lamp body 4 is mounted on the rotating seat 2 so that the lamp body 4 can rotate relative to the fixed seat 1 following the rotating seat 2. Since the bearing 3 can maximize the smoothness of the rotation of the rotating seat 2 relative to the fixed seat 1, and the weight of the lamp body 4 is relatively large, when the rotating seat 2 is adjusted to an oblique position relative to the fixed seat 1 (i.e., a non-zero angle is formed between the axis of the rotating seat 2 and the axis of the fixed seat 1), the rotating seat 2 is easily affected by the weight of the lamp body 4 and causes the adjusted position to shift; therefore, a damping member 5 can be provided to hinder the rotation of the lamp body 4 or the rotating seat 2, so as to apply a certain damping to the lamp body 4 or the rotating seat 2, thereby ensuring that the rotating seat 2 and its components such as the lamp body 4 can stably stay in the adjusted position, wherein the damping member 5 will not cause a sense of obstruction when the user rotates and adjusts the rotating seat 2 and its components such as the lamp body 4.

[0045] Preferably, if Figure 4 , Figure 5 and Figure 7 As shown, the fixing seat 1 also has two protrusions 13 and a first limiting portion 14. The two protrusions 13 correspond to the two bearing 3 holes 12 one by one, so that in the height direction of the fixing seat 1, one protrusion 13 is located directly above the corresponding bearing 3 hole 12; preferably, at least part of the bearing 3 hole 12 can be formed on the protrusion 13, so that the structure of the fixing seat 1 is more compact and reasonable, which is conducive to reducing the volume of the fixing seat 1, thereby facilitating the miniaturization design of the lamp 100. In addition, an avoidance position 15 is formed between the first sides of the two protrusions 13, so that the rotating seat 2 and the lamp body 4 and other components thereon can have a larger rotation adjustment range; at the same time, the design of the protrusion 13 is also conducive to the formation of the avoidance position 15. The first end of the first limiting portion 14 is connected to the second side of the first protrusion 13, and the second end of the first limiting portion 14 is connected to the second side of the second protrusion 13; matchingly, the lamp body 4 is formed with a second limiting portion 41 at the first limiting portion 14, and the second limiting portion 41 can be rotated to be adjacent to the first limiting portion 14. Preferably, when the rotating seat 2 is adjusted to a direct-illumination position relative to the fixed seat 1 (that is, the axis of the rotating seat 2 is parallel to or overlaps with the axis of the fixed seat 1), the second limiting portion 41 is adjacent to the first limiting portion 14, thereby limiting the rotating seat 2 in the direct-illumination position to ensure the position accuracy of the direct-illumination position, so that the lamp 100 can be provided for vertical illumination.

[0046] Among them, the top of the raised portion 13 of the fixed seat 1 is preferably a convex arc surface 131, and matchingly, the lamp body 4 is formed with a concave arc surface 42 at the raised portion 13, and the concave arc surface 42 is arranged to match the convex arc surface 131; preferably, the concave arc surface 42 can be adjacent to the convex arc surface 131, and this design is conducive to the rotation of auxiliary rotating seat 2, lamp body 4 and other components relative to the fixed seat 1.

[0047] Combination Fig. 9In this embodiment, the damping member 5 is installed at the top of the raised portion 13 of the fixed seat 1, and the damping member 5 passes through the convex arc surface 131 of the raised portion 13 and is adjacent to the concave arc surface 42 of the lamp body 4. The damping member 5 can be a first spring plunger or an elastic rubber plug. By arranging the damping member 5 at the top of the raised portion 13 and directly abutting against the lamp body 4, it is possible to better prevent the rotating seat 2 and the lamp body 4 and other components thereon from rotating relative to the fixed seat 1 after adjustment, thereby ensuring that the rotating seat 2 and the lamp body 4 and other components thereon are stable in the adjusted position. Of course, as another optional scheme, in other embodiments, the damping member 5 can also be arranged at the side of the raised portion 13, and the damping member 5 is adjacent to the rotating seat 2, so that the damping member 5 applies damping to the rotating seat 2, thereby also stabilizing the rotating seat 2 and the lamp body 4 and other components thereon in the adjusted position.

[0048] like Figure 2 As shown, the outer ring seat 6 has a second accommodating position 61, and the outer ring seat 6 is provided with a first clamping structure 62 in the second accommodating position 61. The fixing seat 1 is provided with a second clamping structure 6216. When the fixing seat 1 and the outer ring seat 6 are assembled, the fixing seat 1 is arranged in the second accommodating position 61 so that the second clamping structure 6216 is clamped and connected with the first clamping structure 62. The outer ring seat 6 can be used to connect the lamp body unit 101 with an external structure (such as a ceiling, a plate, etc.), and by designing the connection structure between the outer ring seat 6 and the fixing seat 1, the assembly between the outer ring seat 6 and the fixing seat 1 can be done without using fasteners (such as bolts), so as to simplify the assembly steps between the outer ring seat 6 and the fixing seat 1, reduce the difficulty of assembly between the outer ring seat 6 and the fixing seat 1, and improve the overall aesthetics of the lamp body unit 101. Preferably, the first snap-fit ​​structure 62 is an annular snap-fit ​​groove, and the second snap-fit ​​structure 6216 includes a plurality of second spring plungers, and the positioning beads of the second spring plungers are snap-fitted into the annular snap-fit ​​groove; of course, as another optional solution, a snap-fit ​​groove snap-fit ​​structure can also be used to assemble the fixing seat 1 and the outer ring seat 6.

[0049] The optical ring 7 is provided with a first engaging portion 71, and the fixing seat 1 is provided with a second engaging portion 17; when the optical ring 7 is assembled with the fixing seat 1, the second engaging portion 17 is engaged with the first engaging portion 71. When the optical ring 7 is assembled with the fixing seat 1, at least a portion of the optical ring 7 is located in the first accommodation position 11; and preferably, the optical ring 7 is also located in the second accommodation position 61. By providing the first engaging structure 62 and the second engaging structure 6216 to connect the fixing seat 1 and the optical ring 7, the assembly between the outer ring seat 6 and the fixing seat 1 is made simpler and more convenient, and the overall aesthetics of the lamp body unit 101 can be improved; and the provision of the optical ring 7 can improve the lighting effect of the light source 102 of the lamp 100 provided with the lamp body unit 101, and the connection structure design between the optical ring 7 and the fixing seat 1 can make the assembly between the two more convenient and easy to operate, and can improve the overall aesthetics of the lamp body unit 101. Among them, one of the first engaging portion 71 and the second engaging portion 17 is preferably a slot, and the other is preferably a buckle; for example, in this embodiment, the first engaging portion 71 is a buckle, and the second engaging portion 17 is a slot. In addition, the optical ring 7 is preferably an anti-glare ring so that the light emitted by the light source 102 will not overly stimulate the human eye.

[0050] like Figure 3 As shown, the light source 102 is installed in the lamp body 4, so that the lamp body 4 can reliably dissipate heat for the light source 102, so as to ensure the stability and service life of the light source 102. The optical element 103 is preferably installed in the lamp body 4, and the optical element 103 is located between the rotating seat 2 and the light source 102, and the LED lamp beads of the light source 102 are arranged toward the optical element 103, so that the optical element 103 can enhance the lighting effect of the light source 102; of course, as another optional solution, the optical element 103 can also be installed in or on the rotating seat 2; as another optional solution, the optical element 103 can also be arranged in both the rotating seat 2 and the fixed seat 1.

[0051] From the above, it can be seen that through the design of the lamp body unit 101 of the lamp 100, when the rotating seat 2 is rotated and adjusted, the rotating seat 2 can be smoothly rotated and adjusted relative to the fixed seat 1. At the same time, the rotating seat 2 after adjustment has good stability and is not prone to position displacement after adjustment. It can also extend the service life of the lamp 100.

[0052] Lighting system embodiment

[0053] The lighting system includes a control terminal and the lamp described in the above-mentioned lamp embodiment; wherein the lamp also includes a power control unit, and the power control unit is electrically connected to the light source to control the light source to illuminate according to the set mode. The control terminal is used to establish an electrical connection with the power control unit of the lamp, and / or the control terminal is used to exchange information with the power control unit of the lamp. Wherein, the control terminal can be a conventional control panel (such as a mechanical switch panel), an intelligent control panel or a remote control. When the control terminal is a conventional control panel, the control terminal is electrically connected to the power control unit. When the control terminal is an intelligent control panel or a remote control, a first wireless communication module is provided on the power control unit, and a second wireless communication module is provided on the control terminal; the control terminal is electrically connected to the power control unit, and / or the first wireless communication module exchanges information with the second wireless communication module. In addition, the control terminal can also be an intelligent mobile terminal (such as a mobile phone, a tablet computer, an intelligent wearable device, etc.), and can also be an artificial intelligence robot.

[0054] By arranging the above-mentioned lamp, the lighting system can smoothly rotate the rotating seat, lamp body and other components of the lamp when they are rotated and adjusted relative to the fixed seat, while ensuring the stability of the rotating seat, lamp body and other components after adjustment, so that the rotating seat, lamp body and other components after adjustment are not easily shifted in position, and the lamp has a long service life, which is beneficial to reducing the use cost of the lighting system.
