[0002] Turn signals are important indicator lights that are turned on when a motor vehicle turns to alert vehicles and pedestrians in front, behind, left, and right. The turn signal tubes use xenon lamps and are controlled by a single-chip microcomputer circuit. They flash continuously, alternating between left and right. During installation, the turn signal is fixed on the mounting bracket and then directly installed in the corresponding position on the car.
[0003] Currently, when using LED light sources as the light source in automotive turn lights, the LED light sources are installed on lamp holders inside the housing. This has the following problems: the existing turn light housings are sealed structures with poor heat dissipation performance. The heat generated by the LED light sources during operation cannot be dissipated in time, affecting their service life. Utility Model Content
[0004] To address the problems mentioned in the background section, this invention provides an LED turn signal with good heat dissipation performance.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A reflector is provided at the top of each connecting rod, a heat-conducting plate is provided on the inner side of the connecting rod, a first heat dissipation fin is provided on the inner side wall of the heat-conducting plate, and a second heat dissipation fin is provided on the outer side wall of the heat-conducting plate.
[0007] Preferably, a lampshade is detachably connected to the top of the reflector.
[0008] Preferably, the top end of the heat-conducting plate is sealed to the bottom end of the reflector, and the bottom end of the heat-conducting plate is sealed to the top end of the base.
[0009] Preferably, the reflector is provided with a first connecting plate at the top and the lampshade is provided with a second connecting plate at the bottom, and the first connecting plate and the second connecting plate are detachably connected.
[0010] Preferably, the base has a sliding groove inside, the sliding groove is connected to the turn signal, a ventilation groove is provided on the side of the sliding groove inside the base, and a slider is slidably connected inside the sliding groove.
[0011] Preferably, the base has an air inlet and an air outlet at the ventilation slot, and both the air inlet and the air outlet are connected to the slide groove.
[0012] Preferably, the block has a connection channel.
[0013] Preferably, the slide groove is provided with a telescopic rod, and a spring is sleeved on the telescopic rod. The movable end of the telescopic rod is fixedly connected to the slider, and the spring keeps pressing the slider towards the LED light.
[0014] Preferably, a filter element is detachably connected inside the ventilation slot.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The first and second heat dissipation fins on the heat conduction plate can dissipate the heat generated when the turn signal is working in a timely manner, avoiding heat accumulation in the turn signal and preventing the overheating from affecting the service life of the turn signal.
[0017] 2. When using the turn signal, the internal temperature of the turn signal gradually increases, and the internal pressure increases, which pushes the slider to move outward. The connecting channel connects with the air vent, and the gas inside the turn signal can be discharged from the connecting channel to the ventilation slot. When the turn signal cools down, the internal pressure decreases, pushing the slider to move inward into the slide groove. At this time, the connecting channel connects with the air inlet, and outside air can enter the slide groove through the connecting channel, thereby entering the turn signal to balance the internal pressure and prevent the lamp cover from being damaged under pressure, indirectly extending the service life of the turn signal.
[0018] In summary, this utility model overcomes the shortcomings of the prior art, has a reasonable design, good heat dissipation performance, and extends the service life of the turn signal, thus possessing high social value and application prospects. Attached Figure Description

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] Example 1
[0027] Reference Figure 1-4 An LED turn signal with good heat dissipation performance includes a base 1, an LED light 4 at the top of the base 1, and multiple connecting rods 11 at equal angles to the sides of the LED light 4 at the top of the base 1. A reflector 2, which is funnel-shaped, is provided at the top of the connecting rods 11. The LED light 4 is located inside the reflector 2, which can illuminate the cone-shaped area in front, avoid light dispersion, and play a better warning role. A lamp cover 3 is detachably connected to the top of the reflector 2. A heat-conducting plate 12 is provided on the inner side of the connecting rods 11. The top of the heat-conducting plate 12 is sealed to the bottom of the reflector 2, and the bottom of the heat-conducting plate 12 is sealed to the top of the base 1 to ensure the airtightness of the turn signal. The inner wall of the heat-conducting plate 12 is provided with a first heat dissipation fin 121, and the outer wall of the heat-conducting plate 12 is provided with a second heat dissipation fin 122. The first heat dissipation fin 121 and the second heat dissipation fin 122 can conduct heat generated inside the turn signal as much as possible.
[0028] Furthermore, the reflector 2 has a first connecting plate 21 at its top and a second connecting plate 22 at its bottom. The first connecting plate 21 and the second connecting plate 22 are detachably connected by bolts, which facilitates the installation and removal of the lamp cover 3.
[0029] The heat generated by the turn signal during operation can be dissipated in a timely manner through the first heat dissipation fin 121 and the second heat dissipation fin 122 on the heat conduction plate 12, so as to avoid heat accumulation in the turn signal and excessive temperature affecting the service life of the turn signal.
[0030] Example 2
[0031] Reference Figure 1-4The base 1 has an L-shaped slide groove 13, the top of which is connected to the interior of the turn signal. A ventilation slot 131 is located on the side of the slide groove inside the base 1. An air inlet 132 and an air outlet 133 are located at the ventilation slot 131, both connected to the slide groove 13. A slider 14 is slidably connected within the slide groove 13, and a connecting channel 141 is located within the slider 14, connecting to the slide groove 13. When the turn signal is used, the generated heat cannot be completely dissipated, causing changes in the internal pressure of the turn signal. When the internal pressure of the turn signal increases, it can push the slider 14 to move outward, and the connecting channel 141 is connected to the air outlet 133. At this time, the gas inside the turn signal can be discharged from the connecting channel 141 to the ventilation slot 131. When the internal pressure of the turn signal cools down, it pushes the slider 14 to move inward to the slide groove 13. At this time, the connecting channel 141 is connected to the air inlet 132, and the outside air can enter the slide groove 13 through the connecting channel 141, thereby entering the turn signal to balance the internal pressure of the turn signal, preventing the lamp cover 3 from being damaged under pressure, and increasing the service life of the turn signal.
[0032] Furthermore, a telescopic rod 142 is provided inside the slide 13, and a spring 143 is sleeved on the telescopic rod 142. The movable end of the telescopic rod 142 is fixedly connected to the slider 14, and the position of the slider 14 is maintained by the spring 143.
[0033] Furthermore, a filter element 134 is detachably connected inside the ventilation slot 131. The filter element 134 is used to filter dust and moisture in the air entering the turn signal.
[0034] When using the turn signal, even if the heat is dissipated through the heat-conducting plate, it is impossible to completely remove all the heat from the turn signal. The internal temperature of the turn signal gradually increases, and the internal pressure increases, which pushes the slider 14 to move outward. The connecting channel 141 is connected to the air outlet 133. At this time, the gas inside the turn signal can be discharged from the connecting channel 141 to the ventilation slot 131. When the turn signal cools down, the internal pressure decreases, pushing the slider 14 to move inward towards the slide groove 13. At this time, the connecting channel 141 is connected to the air inlet 132. Outside air can enter the slide groove 13 through the connecting channel 141, thereby entering the turn signal to balance the internal pressure of the turn signal, preventing the lamp cover 3 from being damaged under pressure, and extending the service life of the turn signal.
