The efficiency of high-frequency alternating current in the transformer circuit is higher than that of the mains power supply of 50Hz or 60Hz. Therefore, the switching power supply transformer can be made very small.

[0003] At present, the LED switching power supplies on the market not only need to achieve good heat dissipation effects, but also need to ensure good waterproof effects. However, in the existing technology, most LED switching power supplies are difficult to waterproof well while ensuring heat dissipation, resulting in that the LED switching power supplies are difficult to meet the outdoor use requirements, thus affecting the use effects of the LED switching power supplies.

[0010] As a preferred embodiment, the guiding component includes an arc groove and a guiding groove; an arc groove is formed on one side of the light baffle B close to the LED switching power supply body; a guiding groove is formed on one side of the light baffle A close to the LED switching power supply body.

[0011] As a preferred embodiment, the guiding groove is of an inclined structure, and the high end of the guiding groove is arranged in the direction close to the LED switching power supply body, and the low end of the guiding groove is arranged in the direction away from the LED switching power supply body.

[0030] Please refer to Figures 1 to 6 As shown, this embodiment includes an LED switching power supply body 1 and a waterproof component 2;

[0031] The waterproof component 2 is arranged on the LED switching power supply body 1; wherein, the waterproof component 2 includes a waterproof box 201, a waterproof cover 202, a ventilation groove 203, a light baffle A 204, a light baffle B 205, a limit groove A 206, a limit block A 207, a limit groove B 208 and a limit block B 209; the waterproof box 201 is sleeved on the LED switching power supply body 1; the waterproof cover 202 is connected to the waterproof box 201 by bolts; four ventilation grooves 203 are symmetrically opened on both sides of the waterproof box 201; the light baffle A 204 is rotatably arranged in the ventilation groove 203 through a rotating shaft A; the light baffle B 205 is rotatably arranged in the ventilation groove 203 through a rotating shaft B; two limit grooves A 206 are symmetrically opened in the ventilation groove 203; two limit blocks A 207 are symmetrically fixed on both sides of the light baffle A 204; wherein, the limit block A 207 is slidably matched with the limit groove A 206; two limit grooves B 208 are symmetrically opened in the ventilation groove 203; two limit blocks B 209 are symmetrically fixed on both sides of the light baffle B 205; wherein, the limit block B 209 is slidably matched with the limit groove B 208.

[0032] The utility model fixes the LED switching power supply body 1 to the waterproof box 201 by screws through the arrangement of the waterproof component 2. Then, the waterproof cover 202 is fixed to the waterproof box 201 by bolts. During use, when the LED switching power supply body 1 operates, the internal cooling fan is started, so that the cooling fan in the LED switching power supply body 1 dissipates heat from the LED switching power supply body 1, and an air flow is formed in the waterproof box 201, causing the air flow to impact the lightweight baffle B205, making the lightweight baffle B205 rotate in the ventilation slot 203 through the rotating shaft B, and making the limiting block B209 slide from one side of the limiting slot B208 to the other side until the limiting block B209 slides to the other side of the limiting slot B208. At this time, the air flow impacting the lightweight baffle B205 will impact the lightweight baffle A204, making the lightweight baffle A204 rotate in the ventilation slot 203 through the rotating shaft A, and making the limiting block A207 slide from one side of the limiting slot A206 to the other side until the limiting block A207 slides to the other side of the limiting slot A206. At this time, the lightweight baffle A204 and the lightweight baffle B205 rotate to the maximum extent, and the lightweight baffle A204 and the lightweight baffle B205 can waterproof the LED switching power supply body 1. At the same time, the heat-dissipating air flow in the waterproof box 201 can be discharged from between the lightweight baffle A204 and the lightweight baffle B205, realizing the heat dissipation of the LED switching power supply body 1. The utility model has a compact structure, reasonable layout and strong practicability.

[0033] As a preferred implementation scheme, there is an overlapping part between the lightweight baffle A204 and the lightweight baffle B205, and the self-weight of the lightweight baffle A204 is greater than the self-weight of the lightweight baffle B205. This is convenient for waterproofing the LED switching power supply body 1 through the lightweight baffle A204 and the lightweight baffle B205, and the lightweight baffle A204 can make the lightweight baffle B205 return to its original position by its own weight.

[0034] As a preferred implementation scheme, both the limiting slot A206 and the limiting slot B208 are arc-shaped structures, and the rotation angle of the limiting slot A206 is greater than the rotation angle of the limiting slot B208. This is convenient for restricting the rotation angles of the lightweight baffle A204 and the lightweight baffle B205.

[0035] As a preferred embodiment, it further includes a guiding component 3; the guiding component 3 is arranged on the lightweight baffle A 204 and the lightweight baffle B 205; wherein, the guiding component 3 includes an arc-shaped groove 301 and a guiding groove 302; an arc-shaped groove 301 is formed on the side of the lightweight baffle B 205 close to the LED switching power supply body 1; a guiding groove 302 is formed on the side of the lightweight baffle A 204 close to the LED switching power supply body 1; wherein, the guiding groove 302 is of an inclined structure, and the high end of the guiding groove 302 is arranged in the direction close to the LED switching power supply body 1, and the low end of the guiding groove 302 is arranged in the direction away from the LED switching power supply body 1.

[0036] In the utility model, by arranging the arc-shaped groove 301 and the guiding groove 302, the airflow formed by the heat dissipation of the LED switching power supply body 1 in the waterproof box 201 will impact the arc-shaped groove 301, and the acting force of the airflow after impacting the arc-shaped groove 301 is amplified by the arc-shaped groove 301, so as to facilitate the rotation of the lightweight baffle A 204 around the rotating shaft A in the ventilation groove 203, thereby improving the practicability of the utility model.

[0037] The LED switching power supply body 1 is a conventional instrument, and its working principle, size and model are irrelevant to the problems solved by this application, so no more description will be given. The control mode of the utility model is controlled by a controller, and the control circuit of the controller can be realized by simple programming by those skilled in the art.

[0038] Working principle

[0039] For the LED switching power supply with a waterproof structure, first, the LED switching power supply body 1 is fixed to the waterproof box 201 by screws. Then, the waterproof cover 202 is fixed to the waterproof box 201 by bolts. When in use, when the LED switching power supply body 1 operates, the internal cooling fan is started, so that the cooling fan in the LED switching power supply body 1 dissipates heat from the LED switching power supply body 1, and an air flow is formed in the waterproof box 201. The air flow impacts the arc-shaped groove 301, causing the light baffle B205 to rotate in the air-permeable groove 203 through the rotating shaft B, and the limiting block B209 slides from one side of the limiting groove B208 to the other side until the limiting block B209 slides to the other side of the limiting groove B208. Moreover, the acting force of the air flow after impacting the arc-shaped groove 301 is amplified by the arc-shaped groove 301, causing the air flow to impact the guiding groove 302, and the light baffle A204 rotates in the air-permeable groove 203 through the rotating shaft A, and the limiting block A207 slides from one side of the limiting groove A206 to the other side until the limiting block A207 slides to the other side of the limiting groove A206. At this time, the light baffle A204 and the light baffle B205 rotate to the maximum extent, and the light baffle A204 and the light baffle B205 can waterproof the LED switching power supply body 1. At the same time, the heat-dissipating air flow in the waterproof box 201 can be discharged from between the light baffle A204 and the light baffle B205, realizing the heat dissipation of the LED switching power supply body 1.
