Description

Technical Field

[0001] The present invention relates to the technical field of LED lamp adjustment equipment, and in particular to a polarization adjustment device for landscape lighting LED lamps. Background Art

[0002] By rotating the swivel bracket and adjusting the angle of the pitch adjustment component, the overall direction of the lamp can be changed so that the light can irradiate different areas and angles. The polarized lens or reflector can be adjusted according to actual needs to further control the propagation direction and distribution of the light. When it is necessary to concentrate the light on a specific landscape area, the polarized lens or reflector can be adjusted to converge the light in that area; when it is necessary to create a soft and uniform lighting effect, they can be adjusted to disperse the light.

[0003] When landscape lighting LED lamps are in use, the heat energy generated inside will cause the temperature inside the lamp to gradually rise, so ventilation and heat dissipation are required.

[0013] The present invention has the following beneficial effects: (1) The present invention provides a polarization adjustment device for landscape lighting LED lamps. When the LED lamp is turned on, the driving motor is started, the driving motor drives the rotating shaft to rotate, the rotating shaft drives a plurality of heat dissipation fan blades to rotate, the heat dissipation fan blades generate suction force to draw air into the lampshade through the inclined circular box, the suction pipe and the circular groove to dissipate heat. During the air extraction process, moisture in the air will simultaneously enter the inclined circular box, the moisture will be absorbed and filtered by the water-absorbing sponge, and the moisture will be prevented from directly entering the lampshade and affecting the normal light emission of the LED lamp. During the rotation of the rotating shaft, the circular slider will be driven to rotate, the circular slider will drive the L-shaped arc plate to rotate, the L-shaped arc plate will drive the circular plate to rotate, the circular plate will drive the triangular plate to rotate, and the triangular plate will contact the installation When the plate is moved, the circular slider will be driven up by its own inclined surface, and the circular slider will drive the supporting round rod to rise, and the supporting round rod will drive the rotating ring plate to rise, and the rotating ring plate will drive the L-shaped ring plate to rise. The L-shaped ring plate will contact and squeeze the water-absorbing sponge during the rising process, so that the water absorbed in the water-absorbing sponge is squeezed out. At this time, the limit spring is compressed and deformed. After the triangular plate leaves the mounting plate, the limit spring will drive the L-shaped ring plate to leave the water-absorbing sponge under the action of elastic force. In this way, the reciprocating L-shaped ring plate will continuously squeeze the water-absorbing sponge to prevent the water in the water-absorbing sponge from being fully absorbed, resulting in the inability to effectively filter the water in the air entering the lampshade, thereby improving the water absorption strength and sustainability of the water-absorbing sponge. (2) The present invention provides a polarization adjustment device for landscape lighting LED lamps. In hotter places, there are more mosquitoes at night, and the mosquitoes will be attracted near the polarizer. As more and more air enters the lampshade, the air pressure in the lampshade increases, and the air enters the second cavity through the air outlet. The air will push the T-shaped hollow block to move away from the adjustment motor. At this time, the sealing spring is stretched and deformed. When the exhaust slot on the T-shaped hollow block enters the first cavity, the air will enter the first cavity from the exhaust slot, and then be discharged from the connecting pipe, the annular air outlet cover, the through slot, the rotating hollow block, and finally from the air outlet slot to blow the mirror surface of the polarizer. In the process of the air outlet slots discharging air at the same time, since the air outlet slots are distributed in a circular manner from large to small, the rotating hollow block will rotate under the action of the air pressure difference, blowing the polarizer, blowing away the mosquitoes surrounding the polarizer and the dust and impurities attached to the polarizer, preventing the mosquitoes and dust particles from affecting the luminous effect of the device; (3) The polarization adjustment device of a landscape lighting LED lamp of the present invention can affect the flight path of mosquitoes under the action of the air blowing from the air outlet slot, causing the mosquitoes to lose their sense of direction and flight control behavior. When the air suction pipe draws air, it will be done through the annular air suction cover. The annular air suction cover will suck mosquitoes and dust impurities from the vicinity of the polarizer into the inclined circular box under the action of the suction force. When the mosquitoes touch the grid plate in the inclined circular box, they will be electrocuted or coronaized by the grid plate and fall onto the inner wall of the bottom of the inclined circular box. When the driving motor stops running, the mosquitoes and dust impurities will be discharged from the inclined circular box through the gap between the L-shaped arc plates under the action of gravity, thereby improving the clarity of the light of the device and effectively avoiding the interference of mosquitoes on light illumination. (4) The present invention provides a polarization adjustment device for landscape lighting LED lamps. When the device is not used for lighting during the day, the corresponding drive motor will also stop rotating. At this time, the air pressure in the lampshade will drop, and the sealing spring will pull the T-shaped hollow block into the second cavity under the action of elastic force. When the exhaust slot on the T-shaped hollow block returns to the second cavity, the first cavity and the second cavity are no longer connected. At this time, the lampshade will be in a sealed state, which can effectively prevent moisture in the air or dust impurities in the air in rainy weather from entering the lampshade, thereby causing a short circuit in the electronic components in the lampshade, further improving the service life of the device.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 4 As shown, a rectangular groove 509 is opened on the rotating shaft 502, and a circular slider 510 is slidably sleeved on the rectangular groove 509. Two supporting round rods 511 are fixedly installed on the top of the circular slider 510. A rotating ring plate 512 is rotatably installed on the top of the two supporting round rods 511. The top of the rotating ring plate 512 is fixedly connected to the L-shaped annular plate 506.

[0021] The moisture will be absorbed and filtered by the water-absorbing sponge 505 to prevent the moisture from directly entering the lampshade 2 and affecting the normal lighting of the LED lamp 604. During the rotation of the rotating shaft 502, the circular slider 510 will be driven to rotate.

[0022] like Figure 3 As shown, a plurality of L-shaped arc plates 513 are fixedly installed on the outer wall of the circular slider 510, a circular groove 514 is opened at the bottom of the inclined circular box 504, the bottom ends of the plurality of L-shaped arc plates 513 extend out of the circular groove 514, a circular plate 515 is fixedly installed at the bottom ends of the plurality of L-shaped arc plates 513, a mounting plate 516 is fixedly sleeved on the support rod 1, the bottom end of the rotating shaft 502 is rotatably connected to the mounting plate 516, and a triangular plate 517 is fixedly installed at the bottom of the circular plate 515.

The water-absorbing sponge 505 is squeezed to squeeze out the water absorbed in the water-absorbing sponge 505. At this time, the limit spring 508 is compressed and deformed. After the triangular plate 517 leaves the mounting plate 516, the limit spring 508 will drive the L-shaped annular plate 506 to leave the water-absorbing sponge 505 under the action of elastic force. In this way, the reciprocating L-shaped annular plate 506 will continuously squeeze the water-absorbing sponge 505 to prevent the water in the water-absorbing sponge 505 from being fully absorbed, resulting in the inability to effectively filter the water in the air entering the lampshade 2, thereby improving the water absorption strength and sustainability of the water-absorbing sponge 505.

[0024] like Figure 1 and Figure 5 As shown, an adjustment mechanism 6 is provided in the lampshade 2, and the adjustment mechanism 6 includes an adjustment motor 601 fixedly mounted on the inner wall at the top of the lampshade 2, a rotating rod 602 is fixedly mounted on the output shaft of the adjustment motor 601, the bottom end of the rotating rod 602 is rotatably connected to the T-shaped mounting plate 3, a connecting frame 603 is fixedly sleeved on the rotating rod 602, an LED lamp 604 is fixedly mounted on the end of the connecting frame 603, and a polarizing filter 605 is fixedly mounted on the outer wall of the lampshade 2.

The light irradiated by the polarizer 605 changes in intensity through the rotation angle of the LED lamp 604, and then cooperates with the vibration of the polarizer 605 to achieve the polarization adjustment effect.

[0026] like Figure 3 and Figure 6 As shown, an anti-interference mechanism 7 is provided on the outer wall of the inclined circular box 504, and the anti-interference mechanism 7 includes an air suction pipe 701 fixedly installed on the outer wall of the inclined circular box 504, an annular air suction hood 702 is fixedly sleeved on the outer wall of the polarizer 605, the left end of the air suction pipe 701 is communicated with the annular air suction hood 702, and a power grid plate 703 is fixedly installed inside the inclined circular box 504.

The annular suction hood 702 will suck mosquitoes and dust impurities from near the polarizer 605 into the inclined circular box 504 under the action of the suction force. When the mosquitoes touch the electric grid plate 703 in the inclined circular box 504, they will be electrocuted or stunned by the electric grid plate 703 and fall onto the inner wall at the bottom of the inclined circular box 504. When the driving motor 4 stops running, the mosquitoes and dust impurities will be discharged from the inclined circular box 504 through the gap between the L-shaped arc plates 513 under the action of gravity, thereby improving the clarity of the light of the device and effectively avoiding the interference of mosquitoes on light illumination.

[0028] like Figure 6 and Figure 7 As shown, a rotating hollow block 705 is rotatably provided on the outer wall of the annular air suction hood 702, an annular air outlet hood 704 is rotatably provided on the outer wall of the rotating hollow block 705, a plurality of through grooves 706 are provided on the inner wall of the annular air outlet hood 704, and the plurality of through grooves 706 are communicated with the rotating hollow block 705, a plurality of air outlet grooves 707 are provided on the inner wall of the rotating hollow block 705, and the plurality of air outlet grooves 707 are distributed in an annular manner from large to small on the inner wall of the rotating hollow block 705, and a connecting pipe 708 is fixedly installed on the right side of the annular air outlet hood 704.

[0029] When the air outlet slots 707 are simultaneously blowing out air, since the air outlet slots 707 are arranged in a circular pattern from large to small, the rotating hollow block 705 will rotate under the action of the air pressure difference, blowing air to the polarizer 605, thereby blowing away mosquitoes surrounding the polarizer 605 and dust impurities attached to the polarizer 605, preventing the mosquitoes and dust particles from affecting the luminous effect of the device.

[0030] like Figure 8 As shown, a sealing mechanism 8 is provided on the top inner wall of the lampshade 2, and the sealing mechanism 8 includes a rectangular box 801 fixedly mounted on the top inner wall of the lampshade 2, and the right end of the connecting pipe 708 is fixedly connected to the rectangular box 801, and 8 annular air suction hoods 702 and a second cavity 803 are provided in the rectangular box 801, and the connecting pipe 708 is communicated with the first cavity 802.

[0031] The first cavity 802 and the second cavity 803 are no longer connected, and the lampshade 2 is now in a sealed state, which can effectively prevent moisture in the air or dust impurities in the air in rainy weather from entering the lampshade 2, thereby causing a short circuit in the electronic components in the lampshade 2, further increasing the service life of the device.

[0032] like Figure 8As shown, a T-shaped hollow block 804 is slidably installed in the second cavity 803, a plurality of exhaust slots 805 are provided on the outer wall of the T-shaped hollow block 804, a sealing spring 806 is fixedly installed on the left inner wall of the T-shaped hollow block 804, the right end of the sealing spring 806 is fixedly connected to the second cavity 803, and a plurality of air outlet holes 807 are provided on the right side of the rectangular box 801.

[0033] When the exhaust slot 805 on the T-shaped hollow block 804 enters the first cavity 802, air will enter the first cavity 802 from the exhaust slot 805, and then be discharged from the connecting pipe 708, the annular air outlet cover 704, the through slot 706, the rotating hollow block 705, and finally from the air outlet slot 707 to blow the mirror surface of the polarizer 605.

[0034] When the LED lamp 604 is turned on, the driving motor 4 is started, and the driving motor 4 drives the rotating shaft 502 to rotate, and the rotating shaft 502 drives a plurality of cooling fan blades 503 to rotate. The cooling fan blades 503 generate a suction force to draw air into the lampshade 2 through the inclined circular box 504, the suction pipe 701 and the circular groove 514 for heat dissipation. During the ventilation process, moisture in the air will enter the inclined circular box 504 at the same time, and the moisture will be absorbed and filtered by the water-absorbing sponge 505 to prevent the moisture from directly entering the lampshade 2 and affecting the normal lighting of the LED lamp 604. During the rotation of the rotating shaft 502, the circular slider 510 will be driven to rotate, and the circular slider 510 will drive the L-shaped arc plate 513 to rotate, and the L-shaped arc plate 513 will The circular plate 515 is driven to rotate, and the circular plate 515 drives the triangular plate 517 to rotate. When the triangular plate 517 contacts the mounting plate 516, it will drive the circular slider 510 to rise under the action of its own inclined surface. The circular slider 510 will drive the supporting round rod 511 to rise, and the supporting round rod 511 drives the rotating ring plate 512 to rise. The rotating ring plate 512 drives the L-shaped annular plate 506 to rise. The L-shaped annular plate 506 will contact the water-absorbing sponge 505 during the rising process and squeeze the water-absorbing sponge 505 to squeeze out the water absorbed in the water-absorbing sponge 505. At this time, the limit spring 508 is compressed and deformed. After the triangular plate 517 leaves the mounting plate 516, the limit spring 508 will drive the L-shaped The annular plate 506 leaves the water-absorbing sponge 505, and the reciprocating L-shaped annular plate 506 will continuously squeeze the water-absorbing sponge 505 to prevent the water in the water-absorbing sponge 505 from being fully absorbed, resulting in the inability to effectively filter the water in the air entering the lampshade 2, thereby improving the water absorption strength and sustainability of the water-absorbing sponge 505; in hotter places, there are more mosquitoes at night, and the mosquitoes will be attracted near the polarizing filter 605. As more and more air enters the lampshade 2, the air pressure in the lampshade 2 increases, and the air enters the second cavity 803 through the air outlet 807. The air will push the T-shaped hollow block 804 to move away from the adjusting motor 601. At this time, the sealing spring 806 is stretched and deformed. When the T-shaped hollow block 804 is When the exhaust slot 805 on the core block 804 enters the first cavity 802, the air will enter the first cavity 802 from the exhaust slot 805, and then be discharged from the connecting pipe 708, the annular air outlet cover 704, the through slot 706, the rotating hollow block 705, and finally from the air outlet slot 707 to blow the mirror surface of the polarizer 605. In the process of the air outlet slots 707 simultaneously discharging air, since the air outlet slots 707 are distributed in an annular manner from large to small, the rotating hollow block 705 will rotate under the action of the air pressure difference, blowing the polarizer 605, blowing away the mosquitoes surrounding the polarizer 605 and the dust and impurities attached to the polarizer 605, preventing the mosquitoes and dust particles from affecting the luminous effect of the device; The air blowing from the air outlet slot 707 will affect the flight path of the mosquitoes, causing them to lose their sense of direction and flight control behavior. When the air suction pipe 701 draws air, it will be done through the annular air suction cover 702. The annular air suction cover 702 will suck the mosquitoes and dust impurities from near the polarizer 605 into the inclined circular box 504 under the action of the suction force. When the mosquitoes touch the grid plate 703 in the inclined circular box 504, they will be electrocuted or stunned by the grid plate 703 and fall onto the inner wall at the bottom of the inclined circular box 504. When the driving motor 4 stops running, the mosquitoes and dust impurities will be discharged from the inclined circular box 504 through the gap between the L-shaped arc plates 513 under the action of gravity, thereby improving the safety of the device. The clarity of light can effectively prevent mosquitoes from interfering with light illumination; when the device is not used for lighting during the day, the corresponding drive motor 4 will also stop rotating. At this time, since the air pressure in the lampshade 2 will drop, the sealing spring 806 will pull the T-shaped hollow block 804 into the second cavity 803 under the action of elastic force. When the exhaust slot 805 on the T-shaped hollow block 804 returns to the second cavity 803, the first cavity 802 and the second cavity 803 are no longer connected. At this time, the lampshade 2 will be in a sealed state, which can effectively prevent moisture in the air or dust impurities in the air in rainy weather from entering the lampshade 2, thereby causing a short circuit in the electronic components in the lampshade 2, further improving the service life of the device.
