Since the deriving block is provided with a sealing mechanism, the sealing mechanism can be used to close a plurality of heat dissipation through holes on the deriving block, so as to prevent moisture from entering the deriving block. Since the cover body in the lead-out block is made of memory alloy, when the lead-out block is overheated, the cover body can be deformed to open the longitudinal channel for heat dissipation, and when the lead-out block cools down, That is, when the sliding lamp is not working, the longitudinal channel can be closed to prevent moisture.

For example, in order to further describe the structure, function and beneficial effect of the heat dissipation device in detail, the sliding lamp also includes a heat dissipation device, and the heat dissipation device is arranged on the side of the base adjacent to the wire barrel for The sliding lamps dissipate heat.

The heat dissipation device includes a stacked heat conduction plate, a porous plate and a lead-out block. The heat conduction plate is made of aluminum alloy and attached to the base layer. For example, the heat conduction plate is used to dissipate the heat of the sliding lamp, and the porous plate is used to dissipate the heat on the heat conduction plate through gaps. For example, the conduction block is used to dissipate residual heat from the perforated plate. For example, the perforated plate is provided with a plurality of heat dissipation holes, and the plurality of heat dissipation holes are circular holes. The surface of the heat conduction plate is protrudingly provided with locking balls, the middle part of the porous plate is provided with locking holes, the plurality of cooling holes surround the locking holes, and the locking balls of the heat conducting plate are protrudingly arranged on the The clamping holes of the porous plate realize mutual engagement between the heat conducting plate and the porous plate, and at the same time facilitate disassembly of the porous plate from the heat conducting plate.

For example, the cross-section of the mounting narrow hole is triangular or quadrangular, which helps the fitting of the mounting narrow hole and the spiked portion, so that the spiked portion can be smoothly inserted into the mounting narrow hole, At the same time, the gap formed between the installation narrow hole and the sharp part can allow air to enter, so as to discharge heat.

For example, in order to improve the heat dissipation efficiency of the lead-out block, a plurality of heat-dissipation through holes are opened on the lead-out block, and the heat dissipation through-holes pass through the side wall of the lead-out block. For example, the heat dissipation through hole is a circular through hole, and the extending direction of the heat dissipation through hole is arranged parallel to the porous plate and the heat conduction plate. For example, the diameter of the heat dissipation through hole away from the perforated plate is greater than the diameter of the heat dissipation through hole adjacent to the perforated plate, so that the wall thickness of the remaining lead-out block is getting thinner and thinner, which is beneficial for the lead-out block to The heat is dissipated on the heat conducting plate.

However, after long-term use, moisture is easily introduced into the heat dissipation through holes of the lead-out block, thus causing moist gas to form in the heat dissipation through holes. In order to avoid this situation, the heat dissipation device further includes a closing mechanism, and the closing mechanism includes a closing assembly and two closing blocks. The two closed blocks are located at both ends of the lead-out block, that is, one of the closed blocks is located at one end of the lead-out block, and the other is located at the other end of the lead-out block. For example, two ends of the closure component are respectively connected to the two closure blocks, that is, one closure block is connected to one end of the closure component, and the other closure block is connected to the other end of the closure component. When the lead-out block is heated, the sliding lamp is energized, and the closing assembly pushes the two closing blocks away from each other, that is, away from the opposite ends of the lead-out block, thereby opening the plurality of heat dissipation through holes, so that The lead-out block can utilize the plurality of heat dissipation through holes for heat dissipation. And when the sliding lamp is powered off, the closure assembly can pull the two closure blocks, so that the two closure blocks are sealed on the lead-out block, preventing moisture or damp air from entering the heat dissipation channel. hole. For example, the closure block includes a closure plate and a plurality of closure columns, and the plurality of closure columns are respectively aligned with the plurality of heat dissipation through holes, so that the plurality of closure columns can be plugged into the corresponding heat dissipation through holes. For example, in order to facilitate the installation of the closure assembly, a receiving channel is provided in the lead-out block, and the diameter of the receiving channel is larger than the diameter of the heat dissipation through hole. The sealing component is installed in the heat dissipation through hole. For example, the closure assembly includes two connecting rods, two electromagnetic devices and tension springs, the two connecting rods are respectively connected to the two closure blocks, and the two electromagnetic devices are respectively connected to the two On the connecting rod, for example, the electromagnetic device is arranged at an end of the connecting rod away from the closing block, the two electromagnetic devices are arranged opposite each other, and an attraction gap is formed between the two electromagnetic devices. Both ends of the extension spring are respectively connected to the two closure blocks, that is, one end of the extension spring is connected to one of the closure blocks, and the other end of the extension spring is connected to the other closure block. The two electromagnetic devices are connected to a power source. When the LED is not energized, the two electromagnetic devices are not energized and work. At this time, the two closing blocks are pushed close to each other by the tension spring, so that the two closing blocks close the The lead-out block makes the plurality of heat dissipation through holes closed, so as to prevent external moisture and moisture from entering the plurality of heat dissipation through holes, and at the same time, the two electromagnetic devices are in contact with each other. For example, when the two electromagnetic devices are energized, the two electromagnetic devices repel each other, thereby pushing the two closed blocks away from each other and breaking away from the lead-out block, so that the multiple heat dissipation channels on the lead-out block The holes are open, which in turn facilitates the air circulation therein and improves the convective heat transfer efficiency in the outlet block.

For example, in order to prevent electrical conduction when the two electromagnetic devices are in contact with each other, an insulating layer is provided on the electromagnetic device, and the insulating layers on the two electromagnetic devices are oppositely arranged. For example, in order to facilitate the closure column to enter the heat dissipation through hole, the diameter of the closure column gradually decreases along the end away from the closure plate. When the closed column is pulled by the connecting rod, the end of the closed column can first enter the heat dissipation through hole. Since the end of the closed column has a smaller diameter, the During the moving process, the end of the closed column can play a certain guiding role. For example, a plurality of longitudinal passages are opened in the lead-out block, and the longitudinal passages communicate with the plurality of heat dissipation through holes, so that the heat dissipation through holes near the perforated plate communicate with the heat dissipation through holes away from the perforated plate. , through the arrangement of the plurality of longitudinal passages, the plurality of heat dissipation through holes can communicate with each other, so that the heat can be evenly distributed around the lead-out block. For example, in order to facilitate the derivation of the heat of the deriving block, a plurality of deriving holes are provided on the side of the deriving block away from the perforated plate, and a cover body is arranged in the deriving hole, and the cover body is made of memory alloy For example, the covering body is arranged obliquely to the extending direction of the outlet hole, and a bent piece is formed at the end of the covering body. When the temperature of the lead-out block rises, the bent piece of the cover body can be deformed, thereby exposing the lead-out hole, so that the airflow in the plurality of heat dissipation through holes flows out from the plurality of lead-out holes . When the sliding lamp is powered off, the lead-out block gradually cools down. At this time, the bent piece of the cover body can gradually cool down and return to its original shape, thereby closing the lead-out hole and preventing water and moisture from entering the place. in the multiple thermal vias described above.
