[0002] With the rapid development of modern lighting technology, LED light sources have been widely used in indoor and outdoor lighting due to their advantages such as high efficiency, energy saving, long lifespan, and environmental friendliness. However, as users' demands for lighting quality and personalization continue to increase, higher requirements are being placed on the adjustment functions of track LED light sources, especially in terms of focus adjustment, in order to achieve more precise and flexible lighting control and optimal lighting effects.

[0003] The shortcomings of existing technology:

[0004] Currently, track LED light sources are mainly used for lighting in public places such as shopping malls and exhibitions. When displaying specific products, information, or people, it is often necessary to adjust the lighting effect by adjusting the focal length of the light source. However, due to the uncertainty of the number of light sources and the length of the track, current track light sources mainly rely on manual adjustment or fixed-focus design for focal length adjustment. Although manual adjustment can achieve focal length adjustment and has good durability and stability, it is cumbersome and inflexible, making it difficult to meet the diverse lighting needs of today. Especially in track lighting systems, where there are many light heads and they are widely distributed, how to achieve efficient, precise, and cost-effective focal length adjustment has become an urgent problem to be solved.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified. Example

[0033] Please see Figure 1-6 As shown, this utility model provides a track LED light source technical solution: a track LED light source includes a track body 1, a plurality of lamp heads 2 are installed on the upper part of the track body 1, a focusing assembly 3 is installed in the end of the lamp head 2 and the upper cavity of the track body 1, and a driving mechanism 4 for driving the focusing assembly 3 is also installed on the inner side of the track body 1. The focusing assembly 3 includes an adjusting tooth 301, a sliding seat 305 and an electromagnet 308.

[0034] An adjusting tooth 301 is located on the focal length adjusting ring at the end of the lamp head 2. A housing 302 is installed on the lamp head 2 outside the adjusting tooth 301. An adjusting wheel 303, which meshes with the adjusting tooth 301, is rotatably connected inside the housing 302. One end of the axle of the adjusting wheel 303 is connected to a universal flexible shaft 304 for driving the adjusting wheel 303. A sliding seat 305 is slidably connected in a groove inside the track body 1, corresponding to the installation position of the lamp head 2. An adjusting block 306 is rotatably connected to the upper end of the sliding seat 305. The upper end of the adjusting block 306 passes through a transverse groove inside the track body 1 and is rotatably connected to a swing gear 307. The upper end of the swing gear 307 is connected to the end of the universal flexible shaft 304. The swing gear 307 drives the adjusting wheel 303 and the adjusting tooth 301 to rotate through the universal flexible shaft 304. The sliding seat 305 and the adjusting block 306 can only slide horizontally inside the track body 1 and are not affected by the rotation of the swing gear 307. Electromagnet 308 is installed on the inner wall of track body 1 on one side of adjustment block 306. Permanent magnet 309 is fixedly installed on the side of adjustment block 306 adjacent to electromagnet 308.

[0035] The oscillating gear 307 has an upper connecting sleeve 3071 and a lower connecting sleeve 3072 at its two ends. The interface of the upper connecting sleeve 3071 is slidably connected to the end of the universal flexible shaft 304, and the interface of the lower connecting sleeve 3072 is rotatably connected to the connecting rod of the adjusting block 306.

[0036] The number of lamp holders 2 can be determined according to requirements. During installation, the end of the universal flexible shaft 304 is inserted into the upper connecting sleeve 3071 of the swing gear 307, and the positioning shaft at the other end is installed in the mounting hole on one side of the track body 1. A return spring 6 is connected between the inner wall of the track body 1 and the adjusting block 306 for resetting the adjusting block 306 and the swing gear 307. When the sliding seat 305 deviates from the center of the track body 1, the return spring 6 will generate a corresponding pulling force or attractive force.

[0037] When a lamp head 2 on track body 1 needs to adjust its focus, such as Figure 5As shown, the electromagnet 308 below the lamp head 2 is energized by an external controller or user. The electromagnet 308 generates an attractive or repulsive force on the permanent magnet 309 as needed, thereby pushing the adjusting block 306 to one side, causing the swing gear 307 to mesh with the drive mechanism 4. The drive mechanism 4 drives the swing gear 307 to rotate. As the swing gear 307 rotates, the universal flexible shaft 304 also receives power input, ultimately driving the focus adjustment ring to rotate through the adjusting wheel 303 and adjusting gear 301, achieving the focusing effect. After focusing is completed, the electromagnet 308 is de-energized by the external controller or user. After the permanent magnet 309 loses its magnetic influence, the sliding seat 305, adjusting block 306, and swing gear 307 reset under the action of the return spring 6. Alternatively, a sensor can be used to adjust the magnetic force by adjusting the magnitude and direction of the current in the electromagnet 308, thereby adjusting the position of the sliding seat 305 and adjusting block 306 to achieve reset. The focusing component 3 enables rapid adjustment of the focal length of the light source in the track system. Compared with traditional manual adjustment, it is simpler to operate and faster. Especially in track systems with a large number of lamp heads 2, the ease of use and adjustment efficiency are significantly improved, which is more in line with the diverse lighting needs of current track lighting systems.

[0038] The drive mechanism 4 includes a motor 401, a gear drive belt 402, and a gear set 403. The motor 401 is installed in the mounting cavity at one end of the track body 1. The gear drive belt 402 is symmetrically installed in the mounting groove of the track body 1, located on both sides of the oscillating gear 307. The axles at both ends of the gear drive belt 402 provide tension and support. Under the tension effect of the axles, the gear drive belt 402 maintains a certain gap with the inner wall of the mounting groove of the track body 1 to avoid friction during operation. The teeth of the gear drive belt 402 match those of the oscillating gear 307, allowing rotation when the oscillating gear 307 meshes with the gear drive belt 402. Figure 4 As shown, gear set 403 is installed at the lower end of the axle of gear transmission belt 402 and the output end of motor 401. Gear set 403 consists of several individual gears. Motor 401 drives gear transmission belt 402 on both sides to rotate in opposite directions through gear set 403. The operating effect of gear transmission belt 402 is as follows: Figure 6 As shown.

[0039] When the track LED light source needs focusing during operation, the motor 401 is powered on and started by an external controller or user control. The output of the motor 401 drives the gear transmission belts 402 on both sides to rotate synchronously through the gear transmission of the gear set 403. Then, the electromagnet 308 controls the swing gear 307 to mesh with the gear transmission belt 402 on the designated side, so that the swing gear 307 can be driven to rotate in the designated direction through the gear transmission belt 402. Finally, the power is transmitted to the adjusting gear 301, thereby driving the focus adjustment ring on the lamp head 2 to rotate clockwise or counterclockwise, that is, to adjust the focus. Through the drive mechanism 4, the focusing of several lamp heads 2 on the entire track is driven by a single motor 401. The overall design is simple, avoids structural redundancy, reduces the failure rate, saves production costs, and ensures focusing efficiency.

[0040] Inside the track body 1, several support wheels 5 are movably installed on both sides of the swing gear 307 through cavities. The support wheels 5 are used to provide lateral support for the gear transmission belt 402, ensuring transmission efficiency when the swing gear 307 meshes with the gear transmission belt 402.

[0041] The oscillating gear 307 is a bevel gear. When the oscillating gear 307 meshes with the gear transmission belt 402 on one side, the oscillating gear 307 is generally in an inclined state. Therefore, the design of the bevel gear can significantly improve the meshing degree between the two and further improve the transmission efficiency.

[0042] The oscillating gear 307 has an upper connecting sleeve 3071 and a lower connecting sleeve 3072 installed at its two ends, respectively. The interface of the upper connecting sleeve 3071 is slidably connected to the end of the universal flexible shaft 304, and the interface of the upper connecting sleeve 3071 and the end of the universal flexible shaft 304 can be mutually matching polygons, thereby achieving the effect of the oscillating gear 307 driving the universal flexible shaft 304 to rotate synchronously through the upper connecting sleeve 3071 and to slightly extend and retract during rotation. The interface of the lower connecting sleeve 3072 is rotatably connected to the connecting rod of the adjusting block 306, meaning that the rotation of the lower connecting sleeve 3072 will not affect the adjusting block 306.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
