DETAILED DESCRIPTION

[0031] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] An LED lamp bead shield that is convenient for heat dissipation, such as Figure 1-8 As shown, it includes an upper cover shell 1, a mounting rod 2, a condenser cover 3 and a lamp bead body 4; the upper cover shell 1 is fixedly connected to the mounting rod 2; the upper cover shell 1 is fixedly connected to the condenser cover 3 through a connecting portion 1c; the upper cover shell 1 and the condenser cover 3 are jointly fixedly connected to the lamp bead body 4; the upper cover shell 1 is provided with a rain detector;

[0034] It also includes an air duct 5, a cooling fan 6, a filter box 7, a mounting plate 8, a water-absorbing sponge 9 and a shielding component; a plurality of air inlets 1a are opened on the top of the upper cover shell 1, and a plurality of heat dissipation holes 1b are opened on the side of the upper cover shell 1; the upper cover shell 1 is fixedly connected to the filter box 7, and the filter box 7 is communicated with the air inlet 1a, and the filter box 7 is fixedly connected to the mounting rod 2; the filter box 7 is opened with a plurality of air holes 7a; the filter box 7 is fixedly connected to the air duct 5, and the air holes 7a are communicated with the air duct 5, and the air duct 5 is fixedly connected to the lamp bead body 4; a cooling fan 6 is fixedly connected to the inside of the air duct 5; three mounting plates 8 are fixedly connected to the filter box 7, and the mounting plates 8 are fixedly connected to the mounting rod 2; each mounting plate 8 is fixedly connected to a water-absorbing sponge 9, and the water-absorbing sponge 9 is located at the lower side of the air inlet 1a; the upper cover shell 1 is connected to a shielding component.

[0035] The shielding assembly includes a DD motor 101, a push rod 102, a baffle 103, a DD motor 2 104, a movable plate 105 and an insert plate 106; the lamp bead body 4 is fixedly connected to the DD motor 101, and the DD motor 101 is fixedly connected to the air duct 5; the rotating part of the DD motor 101 is fixedly connected to six push rods 102; each heat dissipation through hole 1b is rotatably connected to a baffle 103 through a torsion spring; the mounting rod 2 is fixedly connected to the DD motor 2 104; the rotating part of the DD motor 2 104 is fixedly connected to three movable plates 105, and the movable plates 105 are slidably connected in the filter box 7; each movable plate 105 is fixedly connected to a insert plate 106, and the insert plate 106 is located between the upper cover shell 1 and the water-absorbing sponge 9.

[0036] It also includes a water collecting tank 107 and a drain pipe 108; each movable plate 105 is fixedly connected to a water collecting tank 107, and the water collecting tank 107 is located below the water-absorbing sponge 9; the water collecting tank 107 has a notch 107a; the upper cover shell 1 is fixedly connected to a plurality of drain pipes 108, and in the initial state, the drain pipes 108 are blocked by the water collecting tank 107.

[0037] The bottom surface of the water collecting tank 107 is inclined toward the notch 107 a to facilitate water to be discharged into the drain pipe 108 through the notch 107 a.

[0038] The lower side surface of the heat dissipation through hole 1b is inclined outward.

[0039] The working principle of the above embodiment is as follows: the relevant staff fixes the LED lamp bead through the mounting rod 2 at the scene that needs to be illuminated, illuminates the scene through the lamp bead body 4, and shields the lamp bead body 4 through the upper cover shell 1 and the condenser 3 for focusing and dust prevention; and during the illumination process of the lamp bead body 4, the heat dissipation fan 6 is controlled to rotate to drive the gas flow, so that the outside air enters the filter box 7 through the air inlet 1a, and the water in the air is absorbed by the water-absorbing sponge 9 in the filter box 7, and then flows from the air hole 7a to the air duct 5, and flows along the air duct 5 to the periphery of the lamp bead body 4 in the upper cover shell 1, driving the heat generated by the illumination of the lamp bead body 4 to be discharged from the upper cover shell 1 through the heat dissipation through hole 1b, and dissipating the heat of the lamp bead body 4;

[0040] Moreover, when it rains, rainwater easily enters the upper housing 1 through the air inlet 1a and the heat dissipation through hole 1b, and contacts the lamp bead body 4, causing the lamp bead body 4 to be damaged by moisture. Therefore, when the rain detector on the upper housing 1 detects rain, Figure 3 and Figure 5 As shown, the DD motor 101 is controlled to drive the push rod 102 to rotate counterclockwise from top to bottom, and the push rod 102 rotates to squeeze the corresponding baffle 103, so that the baffle 103 rotates to block the corresponding heat dissipation through hole 1b; at the same time, the DD motor 2 104 is controlled to drive the movable plate 105 and other connected parts to rotate counterclockwise from top to bottom, and the movable plate 105 drives the plug plate 106 and the water collecting tank 107 to rotate, and the plug plate 106 rotates to block the corresponding air inlet 1a, so that when it rains, rainwater cannot enter the upper cover shell 1; subsequently, when the rain detector detects that the rain has stopped, the DD motor 101 and the DD motor 2 104 are controlled to drive the corresponding parts to reset;

[0041] At the same time, in the process that the DD motor 2 104 drives the movable plate 105 and other connected parts to rotate, the DD motor 2 104 drives the movable plate 105 to rotate, cooperates with the mounting plate 8, squeezes the water-absorbing sponge 9, squeezes out the water absorbed by the water-absorbing sponge 9, and collects it in the water collection tank 107 below. When the movable plate 105 continues to rotate and squeezes the water-absorbing sponge 9 to the limit, the plug plate 106 rotates to block the air inlet 1a, and in the initial state, the drain pipe 108 is blocked by the water collection tank 107. As the movable plate 105 drives the water collection tank 107 to rotate, the notch 107a of the water collection tank 107 rotates and connects with the drain pipe 108, and the water collected by the water collection tank 107 is discharged to the outside through the drain pipe 108.

[0042] According to the above working principle, we know that the present invention has the following effects:

[0043] During the lighting process of the lamp bead body 4, the cooling fan 6 is controlled to rotate to drive the air flow, and the heat generated by the lighting of the lamp bead body 4 is discharged from the upper cover shell 1 through the heat dissipation through hole 1b. When the lamp bead body 4 is dissipated, the flowing air is absorbed by the water-absorbing sponge 9 to remove the moisture in the air, so as to avoid the contact of moisture with the lamp bead body 4 when the air flows to the periphery of the lamp bead body 4 to take away the generated heat, so that the lamp bead body 4 is damp, resulting in a short circuit or corrosion of its internal circuit, thereby reducing the service life of the lamp bead body 4. Since LED lamp beads are often installed in outdoor scenes such as streets and roadsides for lighting, when it rains during the use of LED lamp beads, rainwater can easily enter from the inlet. The air port 1a and the heat dissipation through hole 1b enter the upper cover shell 1 and contact the lamp bead body 4, so that the lamp bead body 4 is damaged by moisture. By controlling the DD motor 101 to drive the push rod 102 to rotate, the push rod 102 rotates and squeezes the corresponding baffle 103, so that the baffle 103 rotates to block the corresponding heat dissipation through hole 1b, and by controlling the DD motor 2 104 to drive the movable plate 105 and other connected parts to rotate, the movable plate 105 drives the plug plate 106 to rotate, and the corresponding air inlet 1a is blocked, so that on rainy days, rainwater from the outside cannot enter the upper cover shell 1 through the air inlet 1a and the heat dissipation through hole 1b and contact the lamp bead body 4, thereby ensuring the normal use of the lamp bead body 4;

[0044] During heat dissipation, the water in the air is absorbed and removed by the water-absorbing sponge 9. During the use of the water-absorbing sponge 9, the water absorption performance will gradually decrease, and the water-absorbing sponge 9 needs to be maintained and replaced manually on a regular basis. The maintenance is frequent and the labor cost is high, which is not conducive to practical use. In this regard, the DD motor 2 104 is controlled to drive the movable plate 105 and other connected parts to rotate. The movable plate 105 rotates and cooperates with the mounting plate 8 to squeeze the water-absorbing sponge 9, squeeze out the water absorbed inside the water-absorbing sponge 9, and collect it in the water collecting tank 107 below, so that the water-absorbing sponge 9 can squeeze out the absorbed water regularly during use, thereby increasing the service life of the water-absorbing sponge 9 and reducing the labor maintenance cost; and when the squeezed water is collected in the water collecting tank 107, as the water collecting tank 107 rotates, the notch 107a of the water collecting tank 107 can be connected to the drain pipe 108, so that the squeezed water can be automatically discharged outward through the drain pipe 108, thereby improving the overall convenience of use.

[0045] On the basis of the above technical effects, the present invention also has the following advantages:

[0046] First, the bottom surface of the water collecting tank 107 is set to be inclined toward the notch 107 a. When the notch 107 a is connected to the drain pipe 108, it is convenient for water to be discharged into the drain pipe 108 from the notch 107 a.

[0047] Second, the lower side of the heat dissipation hole 1b is set to be inclined outward. On rainy days, rainwater falling on the heat dissipation hole 1b can flow downward along the downward inclined lower side to avoid rainwater staying in the heat dissipation hole 1b. When the subsequent baffle 103 is reset, the rainwater will enter the upper cover shell 1.

[0048] Example 2

[0049] On the basis of Example 1, Figure 2 and Figure 8-9 As shown, it also includes an electric rotating ring 201 and a brush plate 204; the upper cover shell 1 is rotatably connected to the electric rotating ring 201; the electric rotating ring 201 is fixedly connected to the brush plate 204, and the brush plate 204 is in contact with the surface of the condenser 3.

[0050] It also includes a ventilation pipe 202 and a blowing pipe 203; the brush plate 204 is fixedly connected with the ventilation pipe 202, and the ventilation pipe 202 is connected with the interior of the upper cover shell 1; the ventilation pipe 202 is connected with a plurality of blowing pipes 203.

[0051] It also includes a second air blowing pipe 205 ; the ventilation pipe 202 is connected to the second air blowing pipe 205 .

[0052] The air blowing pipe 203 is arranged to be inclined outward from the surface of the condenser 3, and air is blown to the periphery of the condenser 3 through the air blowing pipe 203 to blow away the mosquitoes around it.

[0053] The ventilation tube 202 and the brush plate 204 are both made of transparent material.

[0054] During the lighting use of the lamp bead body 4 described in Example 1:

[0055] Dust will fall on the surface of the spotlight 3, and the electric swivel 201 is regularly controlled to drive the brush plate 204 to rotate along the surface of the spotlight 3 to brush off the dust on the surface in time; and at night, mosquitoes will stay on or surround the surface of the spotlight 3 under the attraction of the light. Therefore, at night, while controlling the electric swivel 201 to drive the scraper to rotate, the DD motor 101 is simultaneously controlled to drive the push rod 102 to rotate, and the push rod 102 rotates to squeeze the baffle 103, so that the baffle 103 rotates to block the heat dissipation hole 1b, and then the heat dissipation fan 6 is continued to be controlled to work. Since the heat dissipation hole 1b is blocked at this time, the air inlet 1a is connected to the outside, so that after the gas enters from the air inlet 1a, it finally enters the ventilation pipe 202 and is blown out from the air pipe 1 203 and the air pipe 2 205. In conjunction with the rotation of the brush plate 204, the surface of the spotlight 3 is cleaned while the surrounding mosquitoes are blown away.

[0056] According to the above working principle, we know that the present invention has the following effects:

[0057] Since dust will accumulate on the surface of the spotlight 3, the lighting effect of the lamp bead body 4 will be reduced after long-term use. By regularly controlling the electric swivel 201 to drive the brush plate 204 to rotate along the surface of the spotlight 3, the dust on the surface can be brushed off in time to prevent dust from staying on the upper surface of the spotlight 3 and affecting the lighting effect of the lamp bead body 4; and at night, by blocking the heat dissipation through hole 1b, the heat dissipation fan 6 is continuously controlled to work, so that the gas is blown out from the air pipe 1 203 and the air pipe 2 205, and the brush plate 204 rotates to clean the surface of the spotlight 3 while blowing away the surrounding mosquitoes, ensuring that during the night lighting process, no mosquitoes will stay or surround the surface of the spotlight 3 to reduce the lighting effect of the lamp bead body 4.

[0058] On the basis of the above technical effects, the present invention also has the following advantages:

[0059] The ventilation tube 202 and the brush plate 204 are both made of transparent materials. When the lamp bead body 4 is used for lighting, the ventilation tube 202 and the brush plate 204 will not affect the lighting effect of the lamp bead body 4.

[0060] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
