[0033] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] A track spotlight with adjustable focal length in this embodiment, such as Figures 1 to 8 As shown, it includes a lamp body 1, a connecting rod 2 and a drive box 3. The lamp body 1 and the drive box 3 are connected through the connecting rod 2. The bottom of the connecting rod 2 is hinged to the lamp body 1, and the top of the connecting rod 2 is rotatably engaged with the drive box 3.

[0035] A light source assembly 10 is provided at the bottom of the lamp tube body 1, and the light source assembly 10 includes a light source bracket 101 and an LED light source 102. An embedding groove 1011 is provided at the top of the light source bracket 101, and the LED light source 102 is embedded in the embedding groove 1011. By embedding the LED light source 102 in the embedding groove 1011 at the top of the light source bracket 101, the shaking of the light source caused by the movement of the track spotlight or external vibration can be significantly reduced.

[0036] Furthermore, a heat sink 11 is provided within the lamp body 1 and is connected to the top of the light source bracket 101 for dissipating heat from the light source assembly 10. A heat sink 12 is also provided on the top of the lamp body 1. The heat sink 12 is provided with a plurality of heat dissipation holes 121 and heat dissipation channels 122. The plurality of heat dissipation holes 121 and heat dissipation channels 122 are interconnected with the heat sink 11, allowing heat to be discharged from the interior of the lamp body 1 more quickly, thereby preventing the temperature inside the lamp body 1 from being too high and extending the service life of the light source assembly 10.

[0037] Furthermore, a focus adjustment device 13 is connected to the bottom of the light source assembly 10. The focus adjustment device 13 includes a first rotating cylinder 131, a second rotating cylinder 132, and a lens assembly 133. The second rotating cylinder 132 is disposed within the first rotating cylinder 131 and is engaged with the first rotating cylinder 131. The lens assembly 133 is disposed within the second rotating cylinder 132 and is engaged with the second rotating cylinder 132. The lens assembly 133 includes a lens barrel 1331 and a lens 1332 disposed within the lens barrel 1331. A slide 13311 is provided on the outer wall of the lens barrel 1331, and a spiral groove 1321 is provided on the inner wall of the second rotating cylinder 132. The slide 13311 is slidably disposed in the spiral groove 1321. During use, when the first rotating cylinder 131 is rotated, due to the clamping design between the second rotating cylinder 132 and the first rotating cylinder 131, the second rotating cylinder 132 will rotate accordingly, and then the lens cylinder 1331 can move along the direction of the spiral groove 1321, thereby changing the position of the lens 1332 relative to the LED light source 102, thereby achieving the purpose of adjusting the focal length.

[0038] Furthermore, the drive box 3 includes a left cover body 30 and a right cover body 31 that are locked to each other. The left cover body 30 includes a first cover body 301 and a second cover body 302 arranged at the bottom of the first cover body 301. A left rotation slot 3021 is provided at the bottom of the second cover body 302, and a right rotation slot 311 is provided at the bottom of the right cover body 31. A rotating card platform 20 is provided at the top of the connecting rod 2, and the rotating card platform 20 is rotatably set in the left rotation slot 3021 and the right rotation slot 311.

[0039] A first stop 21 is also provided at the top of the connecting rod 2, and the first stop 21 is located below the rotating clamping plate 20. A second stop 312 is provided at the bottom of the right cover 31, and the second stop 312 is located below the right rotating slot 311. When the rotating clamping plate 20 on the connecting rod 2 rotates in the left rotating slot 3021 and the right rotating slot 311, the first stop 21 and the second stop 312 can limit the rotation angle of the connecting rod 2 to a maximum angle of ±350°. When the connecting rod 2 rotates clockwise to 350°, the first stop 21 contacts one side of the second stop 312, and the second stop 312 blocks the connecting rod 2 from continuing to rotate, and vice versa, thereby preventing the connecting rod 2 from over-rotating and thereby breaking the circuit.

[0040] Furthermore, an electrical connector 313 is provided in the right side cover 31. The electrical connector 313 is connected to an external power source to transmit electrical energy to the light source assembly 10. The electrical connector 313 is arranged in the right side cover 31 along the height direction of the right side cover 31. The electrical connector 313 includes a guide column 3131, a power connection plate 3132 and a toggle switch 3133. The power connection plate 3132 is provided on the side wall of the guide column 3131 and passes through the side wall of the right side cover 31. The toggle switch 3133 is provided on the side wall of the guide column 3131 for driving the guide column 3131 to rotate.

[0041] Furthermore, a drive gear 33 is provided at the bottom of the guide post 3131. The guide post 3131 extends through the center of the drive gear 33. The drive gear 33 is arranged along the width of the first cover 301 and the right cover 31, and extends through the side walls of the first cover 301 and the right cover 31, respectively. By providing the drive gear 33, when an external power source drives the drive gear 33, the drive gear 33 can drive the track spotlight to a predetermined position along the track bar. Since the guide post 3131 extends through the drive gear 33, the drive gear 33 can be kept stable during rotation.

[0042] Furthermore, an accommodating space is formed between the left cover 30 and the right cover 31. A color temperature adjustment component 32 electrically connected to the LED light source 102 is provided in the accommodating space. The color temperature adjustment component 32 includes a color temperature controller 321 and a color temperature switch 322. The color temperature controller 321 is provided in the right cover 31, and the color temperature switch 322 is provided in the first cover 301. By toggling the color temperature switch 322, the color temperature of the LED light source 102 can be adjusted, thereby enhancing the functionality of the track spotlight and improving the user experience.
