A type of track spotlight

Abstract

This utility model relates to a track spotlight. It forms a two-dimensional elastic positioning structure by setting a first elastic positioning component between the track power box and the support rod, and a second elastic positioning component between the support rod and the lamp tube. The first elastic positioning component allows the support rod to rotate the lamp tube 360° horizontally, while the second elastic positioning component allows the lamp tube to swing at multiple angles vertically. The elastic force of the components consistently provides stable support to the adjusted position, avoiding the positioning failure issues of traditional damping structures due to wear or the cumbersome adjustment of bolt structures. This ensures the lamp tube remains stable at any preset angle, effectively improving lighting accuracy.

Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a track spotlight. Background Technology

[0002] Track lighting is widely used in commercial lighting, home decoration lighting, and exhibition lighting because it can move flexibly along a track and is easy to use for precise lighting in specific areas. It is also used in clothing stores, art galleries, jewelry stores, living room background walls, and other places.

[0003] However, most track lights currently on the market use simple damping shafts or bolt locking mechanisms to adjust the angle of the light body for vertical swing and horizontal rotation. With damping shafts, the damping force decreases due to wear over time, causing the light body to lose its ability to maintain the preset angle after adjustment. This is especially problematic when the light fixture has weight or is subjected to slight external impacts, leading to displacement and affecting lighting accuracy. With bolt locking, the bolts must be manually loosened and retightened after each adjustment, which is cumbersome and inefficient. Frequent tightening can also cause thread wear, further reducing positioning reliability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a track spotlight with stable angle adjustment, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A track spotlight includes a track power box, a support rod horizontally rotatably mounted on the lower end of the track power box, a lamp tube hinged to the lower end of the support rod that can swing up and down, a light source module provided at one end of the lamp tube, a first elastic positioning component connected between the track power box and the support rod, and a second elastic positioning component connected between the support rod and the lamp tube.

[0007] In some embodiments, a circular groove is provided at the lower end of the track power box, a circular hole is provided at the center of the circular groove, a rotating disk is provided at the upper end of the support rod and rotatably installed in the circular groove, and a rotating column is provided at the upper end of the rotating disk and rotatably installed in the circular hole.

[0008] In some embodiments, the rotating column is formed by two symmetrically arranged hooks, which can be hooked into the circular hole and rotated.

[0009] In some embodiments, the first elastic positioning component includes a first groove disposed on the circular groove, a first positioning post movably disposed in the first groove, a first spring connected between the inner end of the first positioning post and the first groove, a first conical positioning head disposed at the outer end of the first positioning post, and a plurality of positioning grooves cooperating with the first conical positioning head are evenly distributed along the circumference on the inner end face of the rotating disk.

[0010] In some embodiments, a slot is provided on the lamp tube, a rotating shaft is provided in the slot, and a connecting seat is provided at the lower end of the support rod, the connecting seat being rotatably sleeved on the rotating shaft.

[0011] In some embodiments, the second elastic positioning component includes a second groove disposed on one side of the connecting seat, a second positioning post movably disposed in the second groove, a second spring connected between the inner end of the second positioning post and the second groove, a second conical positioning head disposed at the outer end of the second positioning post, and a plurality of positioning holes that cooperate with the second conical positioning head are evenly distributed around the circumference of the side wall of the groove with the pivot as the axis.

[0012] In some embodiments, the light source module includes a heat sink, an LED bead and a bracket are disposed at the center of the front side of the heat sink, the bracket is fixedly connected to the heat sink by screws, and a clearance hole for mounting the LED bead is disposed at the center, a lens is snapped into the bracket, and a reflector is snapped into the front side of the bracket.

[0013] In some embodiments, a plurality of raised strips are evenly distributed on the outer circumference of the reflector cup, and the light source module is secured to the front opening of the lamp tube by the raised strips.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting a first elastic positioning component between the track power box and the support rod, and a second elastic positioning component between the support rod and the lamp tube, a two-dimensional elastic positioning structure is formed. The first elastic positioning component enables the support rod to rotate the lamp tube 360° in the horizontal direction, while the second elastic positioning component enables the lamp tube to swing and adjust at multiple angles in the vertical direction. Furthermore, the elastic force of the elastic components always provides stable support to the adjusted position, avoiding the positioning failure caused by wear of traditional damping structures or the cumbersome adjustment of bolt structures. This ensures that the lamp tube can be stably maintained at any preset angle, effectively improving lighting accuracy. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model based on the specific circumstances.

[0025] like Figure 1-7The track spotlight shown includes a track power box 1, a support rod 2 horizontally rotatably mounted on the lower end of the track power box 1, a lamp tube 3 hinged to the lower end of the support rod 2 that can swing up and down, a light source module 4 provided at one end of the lamp tube 3, a first elastic positioning component connected between the track power box 1 and the support rod 2, and a second elastic positioning component connected between the support rod 2 and the lamp tube 3.

[0026] Specifically, the track power box 1, as the core support and power supply component, is first connected to the external track. On the one hand, it provides stable power to the entire spotlight to ensure that the light source module 4 emits light normally; on the other hand, it provides an installation base for the support rod 2. Through the horizontal rotation connection structure, the support rod 2 can rotate 360° horizontally around the lower end of the track power box 1.

[0027] When the user needs to adjust the horizontal beam direction of the spotlight, they can directly rotate the support rod 2 or the lamp tube 3. The support rod 2 rotates around the rotation connection point of the track power box 1. At this time, the first elastic positioning component between the track power box 1 and the support rod 2 operates synchronously. The elastic components, such as springs and elastic buckles, adapt to the change of rotation angle, providing uniform resistance to the rotation and avoiding sudden angle changes during adjustment. They also lock the current rotation position through elastic force after the user stops applying force, preventing the support rod 2 from rotating on its own. When the user needs to adjust the vertical beam angle of the spotlight, they can rotate the lamp tube 3. The lamp tube 3 swings up and down through the hinge structure at the lower end of the support rod 2. During this process, the second elastic positioning component between the support rod 2 and the lamp tube 3 plays a role. The elastic component generates corresponding elastic force feedback according to the swing angle of the lamp tube 3. On the one hand, it helps the user to accurately control the swing amplitude. On the other hand, after the swing stops, the elastic force stabilizes the lamp tube 3 at the target angle, preventing angle deviation due to the lamp tube's own weight or slight external force.

[0028] See Figure 5 , Figure 6 As shown, a circular groove 21 is provided at the lower end of the track power box 1, and a circular hole 22 is provided at the center of the circular groove 21. A rotating disk 23 is provided at the upper end of the support rod 2 and is rotatably installed in the circular groove 21. A rotating column 24 is provided at the upper end of the rotating disk 23 and is rotatably installed in the circular hole 22. The rotating column 24 is formed by two symmetrically arranged hooks 31. The two hooks 31 can hook into the circular hole 22 and rotate.

[0029] During product assembly, taking advantage of the compatibility between the rotating disk 23 at the upper end of the support rod 2 and the circular groove 21 at the lower end of the track power box 1, the rotating disk 23 is embedded into the circular groove 21. Simultaneously, the rotating column 24 at the upper end of the rotating disk 23 is aligned with the circular hole 22 in the center of the circular groove 21. Through the elastic deformation characteristics of the hooks 31, the rotating column 24 is pressed into the circular hole 22, causing the two hooks 31 to pass through the circular hole 22 and then return to their original shape, hooking onto the upper edge of the circular hole 22. At this point, the rotating disk 23 is confined within the circular groove 21, and the rotating column 24 is axially fixed through the hooks 31 engaging with the circular hole 22. This ultimately completes the detachable connection between the track power box 1 and the support rod 2 without affecting their relative rotation function.

[0030] When the user needs to adjust the horizontal beam direction of the spotlight, a horizontal rotational force is applied to the bracket rod 2. The bracket rod 2 drives the upper rotating disk 23 to move in a circular motion along the inner wall of the circular groove 21. At the same time, the rotating column 24 on the rotating disk 23 rotates synchronously around the central axis of the circular hole 22. During this process, the fitting structure between the circular groove 21 and the rotating disk 23 provides radial guidance for the rotation, preventing the bracket rod 2 from shifting during rotation; while the hook structure between the hook 31 and the circular hole 22 remains axially fixed, preventing the bracket rod 2 from falling off during rotation.

[0031] See Figure 4 As shown, the first elastic positioning component includes a first groove 41 disposed on the circular groove 21, a first positioning post 42 movably disposed in the first groove 41, a first spring 43 connected between the inner end of the first positioning post 42 and the first groove 41, a first conical positioning head 44 disposed at the outer end of the first positioning post 42, and a plurality of positioning grooves 45 that cooperate with the first conical positioning head 44 are evenly distributed along the circumference on the inner end face of the rotating disk 23.

[0032] When no horizontal rotation adjustment is performed, the first spring 43 is in a naturally extended state. Its elastic force pushes the first positioning post 42 outward along the first groove 41, causing the first conical positioning head 44 at the outer end of the first positioning post 42 to embed into a circumferentially distributed positioning groove 45 on the inner end face of the rotating disk 23. At this time, the cooperation between the first conical positioning head 44 and the positioning groove 45 forms a limit, temporarily fixing the support rod 2 at the current horizontal angle and preventing it from rotating arbitrarily due to slight external force or its own weight. When the user needs to adjust the horizontal angle of the support rod 2, a horizontal rotational force is applied to the support rod 2, and the support rod 2 drives the rotating disk 23 to rotate around the central axis of the circular hole 22 of the track power box 1. During the rotation of the rotating disk 23, the positioning groove 45 on its inner wall will exert a squeezing force on the first conical positioning head 44. This force is decomposed along the conical inclined surface of the first conical positioning head 44 into a component force pointing inward towards the first groove 41, pushing the first positioning post 42 to contract into the first groove 41, while compressing the first spring 43. After the first conical positioning head 44 is completely disengaged from the current positioning slot 45, the rotating disk 23 can continue to rotate. As the rotating disk 23 continues to rotate, the next positioning slot 45 will move to a position aligned with the first conical positioning head 44. At this time, the elastic restoring force of the first spring 43 pushes the first positioning post 42 to extend outward again, so that the first conical positioning head 44 is embedded in the new positioning slot 45, completing one positioning switch. When the user stops applying rotational force, the first conical positioning head 44 is stably embedded in the current positioning slot 45, and the elastic force of the first spring 43 continues to act on the first positioning post 42, ensuring that the first conical positioning head 44 and the positioning slot 45 are tightly fitted, forming a reliable positioning lock. At this time, the support rod 2 is fixed at the current horizontal angle. Even if it is subjected to slight vibration or external force, the angle can be kept stable by the limiting effect of the first elastic positioning component, preventing the lighting direction from shifting.

[0033] See Figure 3 , Figure 6 As shown, a slot 51 is provided on the lamp tube 3, a rotating shaft 52 is provided in the slot 51, and a connecting seat 53 is provided at the lower end of the support rod 2. The connecting seat 53 is rotatably sleeved on the rotating shaft 52. The second elastic positioning component includes a second groove 61 provided on one side of the connecting seat 53. A second positioning post 62 is movably provided in the second groove 61. A second spring 63 is connected between the inner end of the second positioning post 62 and the second groove 61. A second conical positioning head 64 is provided at the outer end of the second positioning post 62. A plurality of positioning holes 65 that cooperate with the second conical positioning head 64 are evenly distributed around the circumference of the side wall of the slot 51 with the rotating shaft 52 as the axis.

[0034] The second elastic positioning component has the same structure and principle as the first elastic positioning component, so the second elastic positioning component will not be described in detail here.

[0035] See Figure 1 , Figure 3 , Figure 7 As shown, the light source module 4 includes a heat sink 71. An LED bead and a bracket 73 are disposed at the center of the front side of the heat sink 71. The bracket 73 is fixedly connected to the heat sink 71 by screws 75 and has a clearance hole at its center for mounting the LED bead. A lens 74 is snapped into the bracket 73. A reflector 76 is snapped into the front side of the bracket 73. Several protrusions 81 are evenly distributed on the outer circumference of the reflector 76. The light source module 4 is secured to the front opening of the lamp tube 3 by the protrusions 81.

[0036] First, the LED chip and bracket 73 are fixed to the front center of the heat sink 71 using screws 75. The clearance hole in the center of the bracket 73 provides installation space for the LED chip, ensuring that the LED chip is accurately positioned in the heat dissipation center area of ​​the heat sink 71, laying the foundation for heat conduction during subsequent LED chip operation. A lens 74 is installed inside the bracket 73 using a snap-fit ​​structure. The lens 74 refracts and focuses the light emitted by the LED chip, optimizing the uniformity and illumination range of the light. Then, a reflector 76 is connected to the front of the bracket 73 using a snap-fit ​​mechanism. The reflector 76 reflects the scattered light from the sides and rear of the LED chip to the front, further enhancing the illumination. To improve light utilization and enhance illumination brightness, after assembling the heat sink 71, LED beads, bracket 73, lens 74, and reflector 76, the light source module 4 forms an independent and complete functional unit. At this point, the evenly distributed protrusions 81 on the outer circumference of the reflector 76 become the key structure for connecting the module to the lamp barrel 3. The assembled light source module 4 is aligned with the front opening of the lamp barrel 3. Utilizing the fit between the protrusions 81 on the reflector 76 and the inner wall of the opening of the lamp barrel 3, the light source module 4 is pushed into the lamp barrel 3 until the protrusions 81 are engaged in the corresponding positioning structure of the lamp barrel 3, achieving rapid fixation between the light source module 4 and the lamp barrel 3. After assembly, the LED beads form an indirect heat dissipation channel with the lamp barrel 3 through the heat sink 71. Simultaneously, the lens 74 and reflector 76 work together to convert the light from the LED beads into a directional beam that meets the lighting requirements, achieving precise light distribution by adjusting the angle of the lamp barrel 3.
