[0024] The embodiment of the present application provides an LED driver power supply with a high power factor that is easy to dissipate heat, thereby effectively solving the technical problem that dust and other impurities accumulate on the heat sink 2 during long-term use of the LED driver power supply, thereby affecting the heat dissipation effect of the heat sink 2.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The technical solution in the embodiment of the present application effectively solves the technical problem that dust and other impurities accumulate on the heat sink 2 during the long-term use of the LED driving power supply, which affects the heat dissipation effect of the heat sink 2. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides an LED driving power supply with a high power factor that is easy to dissipate heat. The LED driving power supply with a high power factor that is easy to dissipate heat includes an LED driving power supply body 1, a plurality of heat sinks 2 are fixedly installed on the outside of the LED driving power supply body 1, and connecting mechanisms are provided at both ends of the LED driving power supply body 1. Each connecting mechanism includes a mounting groove 3, a mounting shaft 4, an external thread 5 and a threaded sleeve 6. The mounting groove 3 is arranged on the outside of the LED driving power supply body 1, the mounting shaft 4 is fixedly installed on the inside of the mounting groove 3, the external thread 5 is arranged on the outside of the mounting shaft 4, the threaded sleeve 6 is threadedly connected to the outside of the external thread 5, and a dustproof net 7 is placed above the heat sink 2. The two ends of the dustproof net 7 are respectively slidably connected to the inside of the two mounting grooves 3, and the two ends of the dustproof net 7 are respectively slidably connected to the inside of the two mounting grooves 3. The threaded sleeve 6 is located on the upper surface of the dustproof net 7 by setting the dustproof net 7 and cooperating with the threaded sleeve 6. When the LED driving power supply is used, the two ends of the dustproof net 7 are placed inside the mounting groove 3. At this time, the two ends of the dustproof net 7 are slidably connected to the outside of the mounting shaft 4. At this time, the threaded sleeve 6 is threadedly connected to the outside of the external thread 5. At this time, the dustproof net 7 is installed. When replacing or cleaning the dustproof net 7, the connection between the threaded sleeve 6 and the external thread 5 is released. At this time, the dustproof net 7 can be disassembled by pulling the dustproof net 7. The disassembly and assembly steps of the dustproof net 7 are simple, which is convenient for the user to replace and clean the dustproof net 7. At the same time, the dustproof net 7 is located above the heat sink 2 to prevent dust and other impurities from accumulating in the gap between the heat sink 2, thereby reducing the influence of dust on the heat dissipation effect of the heat sink 2 to facilitate the heat dissipation of the LED driving power supply.

[0028] Both ends of the dustproof net 7 are provided with openings 8, and the two ends of the dustproof net 7 are slidably connected to the outside of the two mounting shafts 4 through the openings 8, which are the connection structure between the dustproof net 7 and the mounting shafts 4. Both ends of the dustproof net 7 are fixedly installed with handles 9, and the handles 9 are concave bodies, which are convenient for pulling the dustproof net 7.

[0029] Both ends of the dustproof net 7 are provided with side panels 10, and a plurality of heat dissipation holes 11 are provided on the outside of each side panel 10. The side panels 10 are fitted with the upper surface of the LED driver power supply body 1 to prevent the dustproof net 7 from fitting with the heat sink 2. Both ends of the dustproof net 7 are fixedly installed with connecting plates 12, and the outside of each side panel 10 is provided with a connecting groove 13. The connecting plate 12 is clamped in the inside of the connecting groove 13 to facilitate the connection and disassembly between the dustproof net 7 and the side panel 10. Both ends of the LED driver power supply body 1 are fixedly installed with a limit plate 14, and each side panel 1 0 is provided with a limiting groove 15 on the lower surface, and the side panel 10 is clamped on the outside of the limiting plate 14 through the limiting groove 15, which is convenient for connecting and disassembling the side panel 10 and the LED driving power supply body 1. By setting the side panel 10 and cooperating with the dustproof net 7, the side panel 10 is clamped on the outside of the limiting plate 14 through the limiting groove 15 before installing the dustproof net 7, and then the connecting plates 12 at both ends of the dustproof net 7 are inserted into the interior of the connecting groove 13. At this time, the dustproof net 7 does not fit on the upper surface of the heat sink 2 so that the air on the surface of the heat sink 2 can flow smoothly, thereby improving the heat dissipation efficiency of the heat sink 2.

[0030] Working principle:

[0031] The first step is to set the dustproof net 7 and cooperate with the threaded sleeve 6. When the LED driving power supply is used, the side plate 10 is clamped on the outside of the limiting plate 14 through the limiting groove 15, and then the connecting plates 12 at both ends of the dustproof net 7 are inserted into the inside of the connecting groove 13. At this time, the two ends of the dustproof net 7 are placed inside the installation groove 3. At this time, the two ends of the dustproof net 7 are slidably connected to the outside of the installation shaft 4. At this time, the threaded sleeve 6 is threadedly connected to the outside of the external thread 5. At this time, the dustproof net 7 is installed. The dustproof net 7 is located above the heat sink 2 to prevent dust and other impurities from accumulating in the gap between the heat sink 2, reducing the influence of dust on the heat dissipation effect of the heat sink 2 so as to facilitate the heat dissipation of the LED driving power supply;

[0032] In the second step, when replacing or cleaning the dustproof net 7, rotate the threaded sleeve 6 to release the connection between the threaded sleeve 6 and the external thread 5. At this time, pull the handle 9 to move the dustproof net 7 upward. At this time, the connection between the dustproof net 7 and the placement groove, the installation shaft 4 and the side panel 10 is released. At this time, the dustproof net 7 is disassembled, which is convenient for the user to replace and clean the dustproof net 7.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
