[0002] LED driver power supply is a power converter that converts power supply into a specific voltage and current to drive LED to emit light. During the use of LED driver power supply, heat dissipation is required to reduce heat loss caused by high temperature. For example, the heat dissipation structure of the driver power supply with announcement number CN214481944U, the utility model adopts a separation tube. When the heat sink needs to be removed, the cover plate is pressed to drive the partition, the filter tube and the contact rod to move down synchronously. The two sets of telescopic springs and the two sets of telescopic rods are in a compressed state. When the contact rod contacts the LED driver power supply, the cover plate is continued to be pressed. This part of the pressing force will be converted into the upward power of the heat sink, the first side plate and the second side plate. When the first side plate and the second side plate are separated from the LED driver power supply, the heat sink is removed, and the two sets of telescopic springs are acted on by their own elastic force to drive the partition, the filter tube and the contact rod to return to their original position for the next use. Through the provided separation tube, the heat sink can be removed without contacting the heat dissipation structure of the driver power supply.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a heat dissipation structure of an LED driving power supply, including a power supply body 100, connecting wires 101 are arranged on both sides of the power supply body 100, and a wiring heat dissipation component 200 is arranged between the outer end of the power supply body 100 and the connecting wire 101. The wiring heat dissipation component 200 can be used to efficiently dissipate the heat at the connection of the power supply body 100, so that the connection will not be damaged due to overheating, thereby increasing the service life of the connection. At the same time, the power supply body 100 can be further radiated from the surrounding surface to provide a suitable temperature environment for the power supply body 100. The wiring heat dissipation component 200 includes an exhaust box 202 and a cooling box 201 respectively installed at the left and right ends of the power supply body 100, and a cooling fan 204 is arranged on the right side of the cooling box 201. The cooling fan 204 can dissipate the outer The wind from the outside is sucked into the cooling box 201, and a plurality of refrigeration plates 206 are arranged inside the cooling box 201. The sucked wind is cooled by the plurality of refrigeration plates 206, so that the temperature of the wind is reduced, thereby improving the heat dissipation effect on the power supply body 100. Distribution pipes 207 evenly distributed on the outside of the power supply body 100 are arranged between the cooling box 201 and the exhaust box 202. After the power supply body 100 is installed on the mounting surface, a plurality of distribution pipes 207 are distributed on the three peripheral surfaces of the power supply body 100, so that the wind can be ejected to dissipate heat from the surface of the power supply body 100. A plurality of air outlet holes 2071 are opened on the lower surface of the distribution pipe 207 along its length direction, and a drying bag located on the left side of the refrigeration plate 206 can be vertically arranged inside the cooling box 201. The drying bag contains silica gel particles to dry the incoming wind.

[0022] In this embodiment, preferably, a primary filter 205 is provided at the right end of the cooling fan 204 and is located on the right side of the fan blade, which can filter and clean the inhaled air. Wind holes are provided on the surface of the cooling plate 206, and multiple cooling plates 206 form an inclined angle with the vertical direction. At the same time, the wind holes provided on the surface facilitate the passage of the air inhaled by the cooling fan 204.

[0023] In this embodiment, preferably, a filter screen 203 is provided on the left side of the exhaust box 202, a rotating clamp plate 2031 is rotatably provided on the left side of the filter screen 203, and a fixed clamp column 2032 which is clamped and connected with the rotating clamp plate 2031 is provided on the left side of the exhaust box 202. The fixed clamp column 2032 is T-shaped when viewed from above, and an arc-shaped hole is provided at the outer end of the rotating clamp plate 2031 for the fixed clamp column 2032 to pass through. The clamping connection between the two facilitates the subsequent disassembly and assembly of the filter screen 203.

[0024] In summary, when in use, the cooling fan 204 works to filter the external wind through the primary filter 205, and the filtered wind acts on the surface of the refrigeration plate 206, and the refrigeration plate 206 cools the wind. The cooled wind passes through the air outlet 2071 and acts on the connection between the connecting line 101 and the power supply body 100, so as to cool the connection and avoid overheating. At the same time, the low-temperature wind will also enter the multiple distribution pipes 207 that are connected through the cooling box 201, and the low-temperature wind acts on the surface of the power supply body 100 through the air outlet 2071 on the surface of the distribution pipe 207, so as to further dissipate the heat from the surface of the power supply body 100, and part of the low-temperature gas flowing in the distribution pipe 207 will also enter the exhaust box 202, and act on the connection point on the left side of the power supply body 100 to cool and dissipate the heat. The whole process improves the heat dissipation effect of the power supply body 100, while avoiding overheating at the connection point, and increasing the stability and safety of the power supply body 100.

[0027] The reinforcing member 300 is preferably provided between the connecting wire 101 and the side surface of the power supply body 100. By providing the reinforcing member 300, the connection point of the connecting wire 101 can be reinforced to prevent it from falling off, so as to avoid loosening and poor contact at the connection point of the connecting wire 101. The reinforcing member 300 includes a fixing ring 301 fixedly sleeved on the inner end of the connecting wire 101, and a fixing lug 303 is fixedly provided on the side surface of the power supply body 100. Two rotating anti-falling plates 302 that are clamped on the fixing ring 301 are rotatably provided inside the fixing lug 303. The rotating anti-falling plate 302 is U-shaped, so that the outer end of the rotating anti-falling plate 302 is conveniently clamped on the side surface of the fixing ring 301, so that the fixing ring 301 and the connecting wire 101 will not move outward due to external force. A positioning block 305 is provided on the inner surface of the rotating anti-falling plate 302, and a slot 304 for the positioning block 305 to pass through is provided on the surface of the fixing ring 301. The two are connected by snapping, which increases the convenience of preventing the fixing ring 301 from being stuck and falling off.

[0028] In this embodiment, preferably, mounting plates 102 are provided at both ends of the power supply body 100 , and a through channel is provided between the heat dissipation fan 204 and the cooling box 201 to facilitate the inhaled wind to enter the cooling box 201 .

At the same time, the wiring heat dissipation component 200 is used to dissipate the heat at the connection point of the connecting wire 101 and the surrounding of the power supply body 100, thereby increasing the stability and safety of the power supply body 100 and reducing the loss caused by the high temperature of the power supply body 100.
