Description
Technical Field
[0001] This utility model relates to the field of ultra-thin track light body technology, specifically an ultra-thin track light body. Background Technology
[0002] Ultra-thin track light bodies are lighting components specifically designed for track lighting systems. They are typically made of lightweight metals or alloys, such as aluminum alloys. Their main characteristic is their thinness, generally between a few millimeters and a dozen millimeters, which allows them to fit the track well without taking up too much space. They also feature simple, smooth lines that can blend seamlessly with various modern interior design styles.
[0003] Because the ultra-thin track light body is thin, the heat dissipation area is insufficient, and heat cannot be quickly dissipated through sufficient air convection or heat conduction. At the same time, the ultra-thin design often uses lightweight materials with poor thermal conductivity, causing heat to accumulate near the LED chip. This can easily generate high temperatures during use, and long-term high temperatures can accelerate light decay or even damage the circuit. Therefore, we propose an ultra-thin track light body.

[0011] Preferably, an extension plate is fixedly connected to one side of the baffle, and a rectangular plate is fixedly connected to the side of the extension plate away from the baffle.
[0012] The effect achieved by the above components is that when the track light body is inserted into the light trough, the extension plate will drive the rectangular plate to fit against the roof, thereby conducting the heat received by the baffle surface to the top surface of the roof, further increasing the heat dissipation effect of the track light body.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-2This utility model provides a technical solution: an ultra-thin track light body, including a track light body 1, with a plurality of lamp heads 2 mounted on the surface of the track light body 1, and a heat dissipation structure 3 provided on the surface of the track light body 1. The heat dissipation structure 3 includes a plurality of brackets 301, which are respectively fixedly connected to both ends of the track light body 1. A pin 302 is slidably inserted into the surface of the bracket 301, and a limiting arm 303 is inserted into the inner wall of the bracket 301. Two round holes 304 are formed on the surface of the limiting arm 303. Grooves 306 are formed on both sides of the track light body 1. The grooves 306 are formed in the track... On both sides of the LED chip inside the street light body 1, the surface of the groove 306 is covered with a baffle 305. The baffle 305 is fixedly connected to the limiting arm 303. Thermal grease 307 is applied to the side of the baffle 305 near the groove 306. By setting the heat dissipation structure 3, it is easy to apply thermal grease 307 to both sides of the LED chip. The thermal grease 307 can conduct heat from the LED chip to the baffle 305, so that the heat generated by the LED chip can be quickly transferred to the baffle 305 and dissipated, effectively reducing the working temperature of the LED chip, reducing the impact of high temperature on its performance, and extending the service life of the lamp.
[0028] Reference Figure 3 and Figure 4As shown in this embodiment: a sealing strip 308, made of rubber, is fitted onto the surface of the baffle 305. The baffle 305 causes the sealing ring to slide into the groove 306, thus preventing further sealing between the baffle 305 and the groove 306. A spring 309 is fitted onto the arc surface of the pin 302. The two ends of the spring 309 are fixedly connected to the pin 302 and the bracket 301, respectively. The spring 309 provides elasticity to ensure a stable fit between the pin 302 and the circular hole 304, thereby ensuring a secure connection between the limiting arm 303 and the bracket 301. An extension plate 310 is fixedly connected to one side of the baffle 305, and a rectangular plate 311 is fixedly connected to the side of the extension plate 310 away from the baffle 305. When the track light body is inserted into the light trough, the extension plate 310 causes the rectangular plate 311 to adhere to the roof, thereby conducting the heat received by the surface of the baffle 305 to the top surface of the roof, further increasing the heat dissipation effect of the track light body. Several fins 312 are fixedly connected to the surface of the extension plate 310. When heat passes through the extension plate 310, the fins 312 on the extension plate 310 will dissipate heat together, thereby further improving the heat dissipation effect of the track light body. Several holes 313 are evenly opened on the surface of the fins 312. The holes 313 on the surface of the fins 312 further improve the air flow. Through air convection, heat is dissipated to the surrounding environment, achieving efficient heat dissipation of the LED chip. Two rectangular rods 314 are fixedly connected to both sides of the track light body 1. A limiting plate 315 is fixedly connected to the end of the rectangular rod 314 away from the track light body 1. The distance between the limiting plate 315 and the track light body 1 is the same as the distance between the two round holes 304 on the limiting arm 303. The limiting plate 315 plays a precise limiting role, preventing the limiting arm 303 from being pulled excessively and moving out of the bracket 301.
[0029] Working principle: When dissipating heat from the track light body 1, first pull the pin 302. The pin 302 moves within the bracket 301 and gradually disengages from the round hole 304. As the pin 302 moves, the spring 309 is stretched. After the pin 302 disengages from the round hole 304, pull the baffle 305. The baffle 305 disengages from the groove 306. The movement of the baffle 305 causes the limiting arm 303 to move. The limiting arm 303 moves towards the limiting plate 315. When the limiting arm 303 is in contact with the surface of the limiting plate 315, the limiting position is achieved. Plate 315 serves as a precise limit, preventing the limit arm 303 from being excessively pulled out of the bracket 301. Loosening the pin 302 allows it to insert into the circular hole 304 on the surface of the limit arm 303. Spring 309 provides elasticity, ensuring a stable fit between the pin 302 and the circular hole 304, thus firmly connecting the limit arm 303 to the bracket 301. This, in turn, secures the baffle 305, which is fixedly connected to the limit arm 303. Thermal grease is then applied to the groove 306 of the baffle 305. Finally, the pin 302 is pulled out of the circular hole 304, and the baffle... 305 is pushed into the groove 306. At this time, the baffle 305 will drive the sealing ring to slide into the groove 306, thereby preventing the thermal grease 307 from overflowing. The sealing ring achieves the effect of further improving the sealing effect between the baffle 305 and the groove 306. Since the groove 306 is opened on both sides of the LED chip, the thermal grease 307 can effectively enhance the heat conduction efficiency from the LED chip to the baffle 305, so that the heat generated by the LED chip can be quickly transferred to the baffle 305 for dissipation. At this time, when installing the track light body, the track light body will drive the extension plate 310 to move. When the lamp body is inserted into the lamp trough, the extension plate 310 will cause the rectangular plate 311 to adhere to the roof, thereby conducting the heat received on the surface of the baffle 305 to the top surface of the roof, further increasing the heat dissipation effect of the track light body. When the heat passes through the extension plate 310, the fins 312 on the extension plate 310 will dissipate heat together, thereby further improving the heat dissipation effect of the track light body. Several holes 313 opened on the surface of the fins 312 further improve the air flow. Through air convection, the heat is dissipated to the surrounding environment, achieving efficient heat dissipation of the LED chip.
