[0002] Track lighting systems typically consist of light clusters and tracks, on which one or more light clusters can be flexibly installed. After installation, spotlights usually require angle adjustments. Some spotlights use universal joints for angle adjustment, but after frequent adjustments, the friction of the universal joints decreases, making angle control difficult. Furthermore, the height of some spotlights requires fine-tuning, but some spotlight poles have fixed lengths and cannot be adjusted, limiting their usability.

[0003] For example, Chinese patent application number CN202021136777.8 discloses an easy-to-install track light. This type of track light uses universal bearings to achieve angle adjustment, but after frequent adjustments, the friction decreases, making the angle difficult to control. Furthermore, this type of track light uses connecting rods and splicing columns to install the spotlights; the lengths of the connecting rods and splicing columns are fixed, and the height of the spotlights cannot be fine-tuned, limiting its application scenarios.

[0020] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a track spotlight.

[0021] The first damping ring 24 provides damping to the ball head 22, preventing the light source module 30 from loosening and sagging, and ensuring proper angle adjustment. The threaded portion 32 formed on the lamp holder 31 can be adjusted and screwed onto the ball head 22, thereby allowing for fine-tuning of the light source module 30 and expanding its application scenarios.

[0022] This application provides a track spotlight, including a power receiving box 10, a universal joint 20, and a light source module 30; a circuit board 15 is disposed inside the power receiving box 10; power terminals 16 on the circuit board 15 extend from the power receiving box 10; the universal joint 20 includes a ball seat 21, a ball head 22, a ball seat cover 23, and a first damping ring 24; the ball seat 21 is screwed onto the power receiving box 10; the first damping ring 24 is disposed in a mounting groove on the inner wall of the spherical groove inside the ball seat 21; the ball head 22... 2. The ball head 22 is located within a spherical groove and can be compressed by the first damping ring 24; the ball seat cover 23 is located at the opening of the spherical groove; the light source module 30 includes a lamp holder 31, a lamp head 35 located within the lamp holder 31, and a lamp cover 37 covering the lamp holder 31; a threaded portion 32 is formed on the lamp holder 31, which can be adjusted and screwed onto the ball head 22; a first terminal connected to the circuit board 15 is provided inside the lamp holder 31; a second terminal on the lamp head 35 can be connected to the first terminal. The power box 10 draws power from the conductive strip 40 within the track 41. When the track spotlight is inserted into the track 41, the power terminal 16 is connected to the conductive strip 40. The circuit board 15 is connected to the first terminal by a wire, preferably an elastic wire. When the ball head 22 rotates in the ball seat 21, the first damping ring 24 can prevent the ball head 22 from loosening and sagging, resulting in better angle control and a longer service life. The first terminal is connected to the circuit board 15 by a wire, which passes through the universal joint 20. The threaded portion 32 formed on the lamp holder 31 can be adjusted and screwed onto the ball head 22, so the position of the light source module 30 can be finely adjusted simply by rotating the light source module 30, making it suitable for a wider range of applications. The lampshade 37 can be attached to the lamp holder 31 by snap-fit ​​or thread. This design facilitates the replacement of the lamp head 35.

[0023] Preferably, the power box 10 includes a box body 11, a bottom cover 12, and a side cover 14. The bottom cover 12 is fitted onto the bottom of the box body 11, and a first screw secures the bottom cover 12 and the box body 11 together. The side cover 14 is fitted onto the side of the box body 11, and a second screw secures the bottom cover 12 and the side cover 14 together. A magnet or Velcro 13 is provided on the bottom cover 12. The magnet or Velcro 13 enhances the firmness between the power box 10 and the guide rail, preventing the light source module 30 from falling off. The box body 11, bottom cover 12, and side cover 14 can be made of metal or plastic. The first screw secures the bottom cover 12 and the box body 11 together, and the second screw secures the bottom cover 12 and the side cover 14 together, ensuring a very high degree of firmness after assembly of the power box 10, preventing loosening. The magnet can be attached to the mounting hole in the bottom cover 12, and the Velcro 13 can be directly attached to the bottom cover 12, which is very convenient.

[0024] Preferably, at least two elastic power-taking terminals 16 extend from the bottom cover 12; each power-taking terminal 16 includes a conductive spring pin 17 and an insulating pin seat 18; the conductive spring pin 17 is disposed on the insulating pin seat 18; the outer wall of the insulating pin seat 18 has an arc-shaped protrusion 19.

When power is drawn, the conductive probe presses against the conductive strip 40, and the electricity flows through the power-taking terminal 16 to the lamp holder 35. A groove is provided inside the guide rail, and the conductive strip 40 is disposed within the groove. The inner wall of the groove has an arc-shaped notch, which can hold the arc-shaped protrusion 19. The arc-shaped protrusion 19 and the arc-shaped notch work together to ensure that the track spotlight is firmly inserted into the track 41 without becoming loose.

[0025] Preferably, the ball seat 21 and the power receiving box 10, and the ball seat cover 23 and the ball seat 21 are connected by threads, and the bottom of the ball seat 21 and the ball seat cover 23 are provided with tightening notches 25. The threaded assembly method is very simple and efficient, and the threads can be finely adjusted. The tightening notches 25 make it easy for workers or machines to tighten the ball seat 21 to the power receiving box 10. This design ensures that there are no other unrelated structures on the outer surface of the ball seat 21, resulting in good overall integrity.

[0026] Preferably, an optical mask 33 is formed on the lamp holder 31; the lamp cover 37 is a light guide cover 37, and part of the light emitted from the ball head 22 can enter the optical mask 33 through the light guide cover and exit from the optical mask 33. The light guide cover 37 is preferably made of a light-guiding plastic material, such as acrylic. The outer surface of the light guide cover is one of the following: frosted surface, face ring, decorative ring, lens, or reflector. Face ring / decorative ring: Located on the outer ring of the spotlight, it can be made of metal, plastic, or chrome-plated material, and the surface may be cut to simulate the refraction effect of diamond. Lens or reflector: Some spotlights are equipped with special lenses (such as COB light sources) or reflectors to enhance light focusing through optical design, forming a starburst effect similar to diamonds, which is more dazzling.

[0027] Preferably, the optical mask 33 is provided with a first heat dissipation hole 34; the first heat dissipation hole 34 is connected to the second heat dissipation hole 36 on the lamp head 35. The first heat dissipation hole 34 is connected to the second heat dissipation hole 36 on the lamp head 35, and the heat inside the lamp head 35 can be dissipated from the second heat dissipation hole 36 and the first heat dissipation hole 34. This design can improve the safety of the lamp and provide better heat dissipation performance.

[0028] Preferably, there are two mounting grooves distributed on the upper inner wall of the spherical groove; a spherical second damping ring is provided on the ball seat cover 23; the ball head 22 can simultaneously press on the first damping ring 24 and the second damping ring. The second damping ring is adapted to the structure of the ball head 22. The cooperation of the first damping ring 24 and the second damping ring can make the damping feel of the ball head 22 movement stronger and the stability better. The first damping ring 24 and the second damping ring are made of high polymer materials such as polyurethane (PU), rubber or tendon, which have both elastic and viscous damping characteristics.

[0029] The preferred assembly steps are: 1. Screw the universal joint 20 onto the housing 11; 2. Screw the bottom cover 12 and side cover 14 onto the housing 11; 3. Screw the light source module 30 onto the ball head 22 to complete the assembly. This assembly method is simpler, easier to assemble, and requires fewer parts.

[0030] Example 2 Example 2 includes the track spotlights from Example 1; the identical parts will not be described again. (Refer to...) Figure 4 The track lighting system shown includes the track spotlights; a conductive strip 40 is installed inside the track 41; the track spotlights are inserted into the track 41, and the power terminal 16 is connected to the conductive strip 40. This type of track system allows for precise angle adjustment of the track spotlights, as well as fine-tuning of their height, making it suitable for a wider range of applications.

[0031] In summary, the key design feature of this invention is that its first damping ring 24 provides damping to the ball head 22, preventing it from loosening and sagging, and making the angle easier to control. The threaded portion 32 formed on the lamp holder 31 can be adjusted and screwed onto the ball head 22. When fine-tuning the lamp head 35, simply rotating the light source module 30 is sufficient to adjust the amount of screwing in or out of the threaded portion 32 onto the ball head 22, thereby achieving fine-tuning and expanding its application scenarios.
