Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an angle adjustment unit and a spotlight equipped with the angle adjustment unit. Background Technology

[0002] Downlights (including spotlights and downlights) are one of the mainstream lighting fixtures for indoor lighting. They can be installed by embedding them into pre-drilled mounting holes in the ceiling, which makes them easy to install and remove.

[0003] like Figure 1 As shown, existing spotlights 9 typically include a heat sink 91, a light-emitting component 92, an adjustment component 93, a connector 94, a reflector 95, and a face ring 96, etc. The radiator 91 has a receiving cavity, and the light-emitting component 92 is installed in the receiving cavity. The adjusting component 93 is connected to the radiator 91 and has a rotating shaft 931. The connecting component 94 is hollow and has a through hole 941. The adjusting component 93 is located inside the connecting component 94, and the radiator 91 is located outside the connecting component 94. The rotating shaft 931 and the through hole 941 are connected by bolts, so that the adjusting component 93 can drive the light-emitting component 92 and the radiator 91 to rotate around the rotating shaft 931 relative to the connecting component 94, so as to adjust the illumination angle of the light-emitting component 92. The reflector is installed in the connecting component 94, and the light-emitting component 92 is set facing the reflector cup 95 to improve the lighting effect of the light-emitting component 92. The face ring 96 is fitted on the connecting component 94 and has a spring clip. The face ring 96 is used to cooperate with the mounting hole on the ceiling to fix the spotlight 9 in the mounting hole.

[0004] However, the existing spotlight 9 has the following shortcomings: First, the connector 94 and the adjusting part 93 need to be connected by bolts, which makes the assembly operation more complicated, which is not conducive to improving production efficiency, and also increases the number of parts and labor costs required for assembly. Secondly, when the connector 94 is assembled with the bolt, it is prone to cracking due to stress. Furthermore, since the connector 94 is an injection molded part, it is easy to strip the threads when there is a situation where the connector 94 and the bolt need to be disassembled and reassembled, which reduces the reliability of the connection between the connector 94 and the adjusting part 93. In addition, the connector 94 needs to reserve enough space for bolt assembly (such as the rotating shaft 931 needs to ensure sufficient length), which will excessively encroach on the internal space of the connector 94. Utility Model Content

[0005] The primary objective of this invention is to provide an angle adjustment unit that simplifies assembly steps, reduces the number of parts, and lowers the risk of damage to parts during assembly.

[0006] The second objective of this invention is to provide a spotlight equipped with the aforementioned angle adjustment unit.

[0007] To achieve the first objective of this utility model, it provides an angle adjustment unit, including an adjusting member and a connecting member. The adjusting member includes a first ring portion and two arms evenly distributed along the first ring portion. The arms extend from the first ring portion to the lower side of the first ring portion. The extended end of the arm portion is provided with a through-hole, which includes a shaft hole and an opening. The opening is located between the end face of the extended end and the shaft hole, and the width of the opening is smaller than the diameter of the shaft hole. The connecting member includes a second ring portion. The inner side of the second ring portion is provided with two pins evenly distributed along the second ring portion. The two pins correspond one-to-one with the two arms. The pins pass through the opening on the corresponding arm portion into the shaft hole and are rotatably connected to the shaft hole.

[0008] As can be seen from the above, through the structural design of the adjusting and connecting parts, the two parts can be quickly assembled simply by inserting the pin on the connecting part into the shaft hole through the opening on the arm of the adjusting part. This eliminates the need for additional bolts to rotate and connect the two parts, avoids cracking of the adjusting or connecting parts after assembly, effectively reduces the number of parts, simplifies the assembly steps to improve assembly efficiency, and also reduces labor and material costs.

[0009] In a preferred embodiment, the second ring portion has a slot at each pin, the slot including a first sidewall and a second sidewall, the first sidewall extending axially along the second ring portion, the extended surface of the second sidewall intersecting the extended surface of the first sidewall, the first distance between the first sidewall and the second sidewall at the top of the second ring portion being greater than the second distance between the two at the bottom of the second ring portion; the pin is located in the slot and between the first sidewall and the second sidewall.

[0010] As can be seen from the above, the slot has a limiting function on the arm. On the one hand, it prevents the arm from disengaging from the pin in the axial direction. On the other hand, through the action of the first side wall and the second side wall, the adjusting component can drive the light-emitting module and heat sink installed on it to rotate between the vertical illumination position and the maximum tilt position, so as to avoid the adjusting component, light-emitting module and heat sink from affecting the lighting effect due to excessive tilt.

[0011] A further option is that the first ring portion has an arc-shaped wall between the two arms, and the arc-shaped wall is located on the side of the first ring portion close to the first side wall.

[0012] As can be seen from the above, by setting an arc-shaped wall at a specific position in the first ring, the arc-shaped wall can block the light emitted by the light-emitting module from shining out of the ceiling through the gap between the adjusting component and the connecting component when the adjusting component drives the light-emitting module and the heat sink installed on it to rotate in an inclined illumination state, thereby reducing light leakage and improving the lighting effect.

[0013] A further improvement is that a light-shielding plate is provided at the top of the second ring between the two slots, the light-shielding plate extends towards the top of the second ring, and the light-shielding plate is located on the side of the second ring closer to the first sidewall.

[0014] As can be seen above, by setting a light-shielding plate at a specific position in the second ring, the light-shielding plate can cooperate with the curved wall to block the light emitted by the light-emitting module in the inclined illumination state from shining into the ceiling through the gap between the adjustment component and the connector, thus preventing light leakage and further improving the lighting effect.

[0015] Another further option is that the pin is provided with a clearance groove, which extends axially from the bottom of the pin into the pin in the second ring; the pin and the shaft hole are interference fit.

[0016] As can be seen from the above, the design of the clearance groove can weaken the structural strength of the pin without affecting the structural strength of the pin and the reliability of the connection between the pin and the slot, making it easier for the pin to pass through the opening and connect with the shaft hole. On the other hand, it can also reduce the amount of material used, thereby helping to reduce costs.

[0017] Another further option is to have a reflective cup slot below each slot in the second ring.

[0018] As can be seen from the above, this design allows the reflector cup to be directly engaged with the second ring via its elastic buckle, enabling quick assembly of the two without the need for additional locking components, effectively reducing costs and improving production efficiency.

[0019] Another preferred embodiment is that the first ring portion is also provided with a radiator positioning groove, a radiator connecting through hole and a lens rib position. The radiator positioning groove is located on the outer periphery of the first ring portion, the radiator connecting through hole passes through the first ring portion along the axial direction of the first ring portion, and the lens rib position is located on the top of the first ring portion.

[0020] As can be seen from the above, the radiator positioning groove is used to cooperate with the positioning ribs on the radiator to prevent mistaken assembly of the adjusting parts and the radiator. The radiator connecting through hole is assembled with the radiator through locking parts (such as bolts) to ensure the reliability and firmness of the connection between the two. The lens rib is used to position and fix the lens, realize the quick assembly of the lens, and make the lens installation not require additional locking parts for connection, simplifying the assembly steps, improving assembly efficiency and reducing costs.

[0021] A further option is to have multiple ribs on the inner ring of the first ring along its circumference, with the ribs extending axially along the first ring.

[0022] As can be seen from the above, since the light-emitting end of the light-emitting module installed in the heat sink is oriented towards the first ring, and the structure of multiple ribs can be used to shield and guide the emitted light of the light-emitting module, thereby achieving anti-glare.

[0023] A further proposed solution is that the angle adjustment unit also includes a face ring and two spring clips. The face ring includes a third ring and an eave. The inner circle of the third ring has a mating part, and the eave surrounds the bottom of the third ring. The two spring clips are evenly distributed around the circumference of the third ring and are installed on the third ring. The second ring also has two or more elastic clips. The third ring is fitted onto the second ring, and the elastic clips engage with the mating part.

[0024] As can be seen from the above, the above design makes the assembly of the face ring and the connector faster and more convenient, and there is no need to configure additional locking parts to connect the two, which can improve assembly efficiency and reduce costs. The face ring, through the cooperation of its eaves and spring clips, can quickly install the lamp with this angle adjustment unit into the preset mounting hole on the ceiling, and makes the lamp and the mounting hole more convenient to disassemble and assemble.

[0025] To achieve the second objective of this utility model, this utility model provides a spotlight, including a heat sink and a light-emitting module. The light-emitting module is installed inside the heat sink. The spotlight also includes the aforementioned angle adjustment unit, with a first ring portion installed inside the heat sink and an arm portion extending out of the heat sink.

[0026] As can be seen from the above, by setting the angle adjustment unit, the spotlight can effectively simplify the assembly steps, reduce the number of parts, and reduce the risk of damage to parts during the assembly process. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0037] Spotlight Examples Reference Figure 2 and Figure 3 The spotlight 100 includes an angle adjustment unit 101, a heat sink 102, a reflector 103, and a light-emitting module. Combined with... Figure 4 and Figure 5 The angle adjustment unit 101 includes an adjustment component 1, a connecting component 2, a face ring 3, and a spring clip 4.

[0038] Combination Figure 6 The adjusting member 1 includes a first ring portion 11 and two arms 12. The two arms 12 are evenly distributed around the first ring portion 11 and extend from the first ring portion 11 to the lower side of the first ring portion 11. The extended end of the first arm portion 12 is provided with a locking position 121, which penetrates the first arm portion 12 along its thickness direction.

[0039] The locking position 121 includes a shaft hole 1211 and an opening 1212. The opening 1212 is located between the end face of the protruding end of the arm 12 and the shaft hole 1211, and the opening 1212 communicates with the locking position 121. The opening 1212 is used for the pin 211, which is fitted to the connector 2, to enter and exit the shaft hole 1211. The position design of the opening 1212 facilitates the assembly and disassembly of the locking position 121 and the pin 211, and also gives the arm 12 a certain elastic deformation capability at the locking position 121. The width of the opening 1212 is smaller than the diameter of the shaft hole 1211, so that when the shaft hole 1211 and the pin 211 are assembled, the pin 211 will not come out of the locking position 121 without applying a pulling force to the adjusting member 1 and / or the connector 2.

[0040] Combination Figure 7The connector 2 includes a second ring portion 21, on the inner side of which are two pins 211. The two pins 211 are evenly distributed circumferentially along the second ring portion 21 and are parallel to the radial direction of the second ring portion 21. The two pins 211 correspond one-to-one with the two arms 12, such that when the connector 2 is assembled with the adjusting member 1, one pin 211 passes through the opening 1212 on the corresponding arm 12 into the shaft hole 1211 and is rotatably connected to the shaft hole 1211. Compared with the existing method that requires bolts to rotate the connecting piece 2 and the adjusting piece 1, this utility model, through the structural design of the adjusting piece 1 and the connecting piece 2, allows for quick assembly of the two parts by simply inserting the pin 211 on the connecting piece 2 into the shaft hole 1211 through the opening 1212 on the arm 12 of the adjusting piece 1. This eliminates the need for additional bolts to rotate the two parts, avoids cracking of the adjusting piece 1 or the connecting piece 2 after assembly, effectively reduces the number of parts, simplifies the assembly steps to improve assembly efficiency, and also reduces labor and material costs.

[0041] Preferably, the pin 211 and the shaft hole 1211 are interference-fitted. This design, on the one hand, avoids relative wobbling between the pin 211 and the shaft hole 1211 due to the presence of gaps, thus improving the tightness of the connection between the two. On the other hand, it allows for damping between the pin 211 and the shaft hole 1211, so as to prevent the adjusting component 1 from rotating undesirably relative to the connecting component 2 due to the gravity of the heat sink 102, the light-emitting module, etc., thereby ensuring that the light-emitting module is stably maintained at the desired illumination angle, improving the user experience and the product reliability of the spotlight 100.

[0042] Furthermore, combined Figure 8 The pin 211 is provided with a clearance groove 2111, which extends axially from the bottom of the pin 211 into the second ring 21. The design of the clearance groove 2111 can, on the one hand, weaken the structural strength of the pin 211 without affecting the structural strength of the pin 211 and the reliability of the connection between the pin 211 and the locking position 121 on the arm 12, making it easier for the pin 211 to pass through the opening 1212 and connect with the shaft hole 1211, and preventing the arm 12 from cracking at the locking position 121; on the other hand, it can also appropriately reduce the material used in the connector 2, which helps to reduce costs.

[0043] Furthermore, the second ring portion 21 preferably has a slot 212 at each pin 211, the slot 212 including a first sidewall 2121, a second sidewall 2122, and a third sidewall. The first sidewall 2121 extends axially along the second ring portion 21; the second sidewall 2122 is disposed opposite to the first sidewall 2121, and the extended surface of the second sidewall 2122 intersects the extended surface of the first sidewall 2121, such that a first distance W1 between the first sidewall 2121 and the second sidewall 2122 at the top of the second ring portion 21 is greater than a second distance W2 between the two (i.e., the first sidewall 2121 and the second sidewall 2122) at the bottom of the second ring portion 21; the pin 211 is located within the slot 212, and the pin 211 is located between the first sidewall 2121 and the second sidewall 2122; the third sidewall is located at the protruding end of the pin 211. By setting the slot 212, it can limit the arm 12, on the one hand, preventing the arm 12 from separating from the pin 211 in the axial direction; on the other hand, under the action of the first side wall 2121 and the second side wall 2122, the adjusting member 1 can drive the light-emitting module and heat sink 102 installed on it to rotate between the vertical illumination position (i.e., the axis of the first ring 11 is parallel to the axis of the second ring 21) and the maximum tilt position (at this time, there is a non-zero angle between the axis of the first ring 11 and the axis of the second ring 21, the size of which is determined according to the design requirements of the spotlight 100), so as to avoid the adjusting member 1, the light-emitting module and the heat sink 102 from affecting the lighting effect due to excessive tilting.

[0044] Furthermore, in order to ensure the lighting effect when the light-emitting module is in an inclined illumination state, the following design is made for the adjustment component 1 and the connecting component 2: Combination Figure 9 An arc-shaped wall 111 is provided between the two arms 12 of the first ring portion 11 of the adjusting member 1. After the adjusting member 1 and the connecting member 2 are assembled, the arc-shaped wall 111 is located on the side of the first ring portion 11 near the first side wall 2121 of the slot 212. By providing the arc-shaped wall 111 at a specific position of the first ring portion 11, the arc-shaped wall 111 can block the light emitted by the light-emitting module from shining into the ceiling through the gap between the adjusting member 1 and the connecting member 2 when the adjusting member 1 drives the light-emitting module and heat sink 102 installed on it to rotate in an inclined illumination state, thereby reducing light leakage and improving the lighting effect.

[0045] The connector 2 has a light-shielding plate 213 on the second ring 21. The light-shielding plate 213 is located between the two slots 212 and extends to the top of the second ring 21 (i.e., the side of the second ring 21 closer to the first ring 11), and the light-shielding plate 213 is located on the side of the second ring 21 closer to the first side wall 2121. By setting the light-shielding plate 213 at a specific position on the second ring 21, the light-shielding plate 213 can cooperate with the curved wall 111 to block the light emitted by the light-emitting module in an inclined illumination state from shining into the ceiling through the gap between the adjusting member 1 and the connector 2, thereby achieving the purpose of preventing light leakage and further improving the lighting effect.

[0046] The heat sink 102 is mounted on the adjusting member 1. In this example, the first ring portion 11 and the light-emitting module of the adjusting member 1 are both located inside the heat sink 102, and the light-emitting end of the light-emitting module is set towards the first ring portion 11, while the arm portion 12 of the adjusting member 1 extends out of the heat sink 102 (that is, the heat sink 102 is located on the upper side of the first ring portion 11). Preferably, the first ring portion 11 is further provided with a radiator positioning groove 112 and a radiator connecting through hole 113. The radiator positioning groove 112 is located on the outer periphery of the first ring portion 11, and the radiator connecting through hole 113 passes through the first ring portion 11 along the axial direction of the first ring portion 11. Correspondingly, the radiator 102 is provided with a positioning rib and a connecting hole. When the adjusting member 1 is assembled with the radiator 102, the positioning rib of the radiator 102 is inserted into the radiator positioning groove 112 of the first ring portion 11 to prevent mistaken assembly and achieve quick positioning. Then, a locking member (such as a bolt) passes through the radiator connecting through hole 113 of the first ring portion 11 and connects with the corresponding connecting hole on the radiator 102, thereby completing the fixed connection between the two.

[0047] In addition, the first ring portion 11 is provided with a lens rib position 115. The lens rib position 115 is located at the top of the first ring portion 11. The lens rib position 115 is used to position and fix the lens of the light-emitting module, realize the rapid assembly of the lens, and with the cooperation of the heat sink 102, the lens installation does not require additional locking parts for connection, simplifying the assembly steps, improving assembly efficiency and reducing costs.

[0048] Since the light-emitting end of the light-emitting module is positioned towards the first ring portion 11 of the adjusting member 1, multiple ribs 114 are provided on the inner ring of the first ring portion 11 to improve the anti-glare effect of the spotlight 100, and the multiple ribs 114 are evenly distributed along the circumference of the first ring portion 11; wherein, the ribs 114 extend along the axial direction of the first ring portion 11. This design utilizes the structure of multiple ribs 114 to guide and shield the emitted light from the light-emitting module, thereby achieving the purpose of anti-glare.

[0049] The face ring 3 includes a third ring portion 31 and an eave portion 32, with the eave portion 32 surrounding the bottom of the third ring portion 31. When the face ring 3 is assembled with the connector 2, the third ring portion 31 is fitted onto the second ring portion 21. Preferably, the inner ring of the third ring portion 31 is provided with a mating portion 311, and correspondingly, the second ring portion 21 is provided with two or more elastic buckles 215, so that when the face ring 3 is assembled with the connector 2, the elastic buckles 215 engage with the mating portion 311, thereby achieving rapid assembly of the two without the need for additional locking components to connect them, which can improve assembly efficiency and reduce costs.

[0050] There are two spring clips 4, which are evenly distributed along the axial direction of the third ring portion 31 of the face ring 3, and the spring clips 4 are installed on the third ring portion 31. The spring clips 4 and the eaves portion 32 of the face ring 3 form a clamping position, which allows the spotlight 100 to be quickly installed into the preset mounting hole on the ceiling, and makes it easier to install and remove the spotlight 100 from the mounting hole.

[0051] The reflector cup 103 is mounted on the second ring portion 21 of the connector 2. In this embodiment, the reflector cup 103 is provided with an elastic buckle, and correspondingly, the second ring portion 21 is provided with a reflector cup 103 slot 214. When the reflector cup 103 is assembled with the connector 2, the elastic buckle on the reflector cup 103 engages with the reflector cup 103 slot 214 on the second ring portion 21 to achieve quick assembly without the need for additional locking components, effectively reducing costs and improving production efficiency. Preferably, the reflector cup 103 slot 214 is located below the slot 212. This design optimizes the structure of the connector 2 and reduces production costs.

[0052] In summary, by designing the angle adjustment unit 101 of the spotlight 100, the assembly steps of the spotlight 100 can be effectively simplified, the number of parts can be reduced, and the risk of damage to parts during the assembly process can be reduced.

[0053] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
