Description

Technical Field

[0001] This invention relates to the field of LED lighting technology, specifically to an LED lamp with an adjustable focusing plate angle. Background Technology

[0002] LED lighting fixtures refer to devices that can transmit, distribute, and change the light distribution of LED light sources. They include all components other than the LED light source itself, which are used to fix and protect the LED light source. During the use of LED lighting fixtures, a light-concentrating plate can be used to concentrate the light from the LED lighting fixtures.

[0003] A search revealed a patent with authorization publication number CN207034671U, which discloses an LED lamp with an adjustable reflective angle of the focusing plate. The lamp includes a heat sink, on the upper surface of which, from left to right, are arranged a support column, an adjustment device, and a connecting rod. A focusing plate is movably connected to one side of the support column via a first movable rod. A lampshade is fixedly connected to the lower surface of the heat sink, and a fixing plate is fixedly connected to the lower surface of the connecting rod. An LED bulb is mounted on the fixing plate, and a heat-conducting plate is fixedly connected to the fixing plate and the heat sink via bolts. The adjustment device includes a motor. While this patent allows adjustment of the focusing plate angle by rotating a second rotating rod, it is inconvenient to adjust the illumination height of the focusing plate when the lamp is installed on a high ceiling, thus affecting the effectiveness of the LED lamp.

[0004] Therefore, it is necessary to design an LED lamp with an adjustable focusing plate angle that facilitates the adjustment of the LED lamp and the illumination height of the focusing plate. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies that make it inconvenient to adjust the illumination height of the focusing plate, the technical problem to be solved is to provide an LED lamp with an adjustable focusing plate angle that facilitates the adjustment of the illumination height of the LED lamp and the focusing plate.

[0006] The technical solution of the present invention is: an LED lamp with an adjustable focusing plate angle, comprising a bracket, an LED lamp and a first focusing plate, wherein the LED lamp is installed at the bottom of the bracket, and at least two first focusing plates are evenly spaced at the bottom of the bracket, each first focusing plate being rotatably connected to the bracket, the first focusing plate being used to concentrate light, and further comprising a driving mechanism, a rotating mechanism and a lowering mechanism, wherein the bracket is provided with a driving mechanism for automatically rotating the first focusing plate, the upper part of the bracket is provided with a rotating mechanism for adjusting the height of the LED lamp and the first focusing plate, and a lowering mechanism for automatically adjusting the height of the LED lamp and the first focusing plate is provided between the rotating mechanism and the driving mechanism.

[0007] Furthermore, the drive mechanism includes a first motor, a winding wheel, a connecting rod, and a pull rope. The first motor is installed inside the bracket, and the winding wheel is connected to the output shaft of the first motor. A connecting rod is connected to the top of each first focusing plate, and a pull rope is connected between each connecting rod and the winding wheel. The rotation of the winding wheel can wind up the pull rope.

[0008] Furthermore, the rotating mechanism includes a connecting plate, a first contact rod, a rotating shell, and a fixed plate. The connecting plate is connected to the upper part of the bracket, the first contact rod is placed on the upper part of the connecting plate, the rotating shell is connected to the outer side of the first contact rod, and the fixed plate is rotatably connected to the upper part of the rotating shell.

[0009] Furthermore, the lowering mechanism includes a first gear, a nut, a screw, a connecting frame, and a second gear. The first gear is connected to the output shaft of the first motor and is located above the winding reel. Two nuts are connected to the first contact rod and contact the rotating housing. A screw is threaded onto each nut. A connecting frame is connected to the bottom of the connecting plate. The middle of each screw is rotatably connected to the connecting plate and the connecting frame. The upper parts of both screws are connected to the adjacent connecting frame via bearings. The lower parts of both screws are connected to the second gear, and the first gear meshes with the two second gears.

[0010] Furthermore, it also includes an extension mechanism for extending the angle of light concentration. The extension mechanism includes a sliding rod, a sliding block, and a second concentrating plate. There are at least two sets of sliding rods, with two sliding rods in each set. Each first concentrating plate is connected to a set of sliding rods. Sliding blocks are slidably connected to the two sliding rods in each set. A second concentrating plate is installed between every two adjacent sliding blocks. The second concentrating plate is used to concentrate the light. The second concentrating plate is slidably connected to the first concentrating plate.

[0011] Furthermore, it also includes a pushing mechanism for moving the second focusing plate outward. The pushing mechanism includes a limit frame, a second contact rod, and an elastic element. There are at least two sets of limit frames, with two limit frames in each set. At least two sets of limit frames are connected at intervals at the lower part of the support. The limit frames in each set are located on the outer side of the adjacent first focusing plate. Each second focusing plate has two second contact rods connected to its top. The second contact rods can rotate upward to contact the adjacent limit frames. An elastic element is sleeved on each of the two sliding rods in each set. The two ends of the elastic element are connected to the sliding rod and the sliding block, respectively.

[0012] Furthermore, it also includes a rotating mechanism for adjusting the focusing and concentrated irradiation range of the first and second focusing plates.

The rotating frame has evenly spaced toothed holes, and the third gear meshes with the toothed holes.

[0013] Furthermore, the limit frame is U-shaped.

[0014] The beneficial effects are: 1. By starting the first motor, the first concentrator can be rotated upward, making it easy to adjust the angle at which the first concentrator focuses the light; 2. By meshing the first gear and the second gear, the LED lamp and the first concentrator can be moved downward, thereby achieving the purpose of adjusting the illumination height of the LED lamp and the concentrator.

[0015] 2. By contacting the second contact rod with the limiting frame, the second concentrating plate can be moved outward, thereby achieving the effect of extending the angle of light concentration.

[0016] 3. The operator starts the second motor, which can rotate the LED lamp, the first focusing plate and the second focusing plate, thereby adjusting the concentrated irradiation range of the first focusing plate and the second focusing plate. Attached Figure Description

Detailed Implementation

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-5 As shown, an LED lamp with an adjustable focusing plate angle includes a bracket 1, an LED lamp 2, a first focusing plate 3, a driving mechanism 4, a rotating mechanism 5, and a lowering mechanism 6. The LED lamp 2 is bolted to the bottom of the bracket 1. Four first focusing plates 3 are evenly spaced at the bottom of the bracket 1. Each first focusing plate 3 is rotatably connected to the bracket 1. The first focusing plates 3 are used to concentrate the light. The driving mechanism 4 is provided inside the bracket 1. The rotating mechanism 5 is provided on the upper part of the bracket 1. The lowering mechanism 6 is provided between the rotating mechanism 5 and the driving mechanism 4.

[0029] like Figure 1 and Figure 3 As shown, the drive mechanism 4 includes a first motor 41, a winding wheel 42, a connecting rod 43, and a pull rope 44. The first motor 41 is bolted to the top of the bracket 1. The winding wheel 42 is connected to the output shaft of the first motor 41. The top of each first focusing plate 3 is bolted to a connecting rod 43. Each connecting rod 43 is connected to the winding wheel 42, and a pull rope 44 is connected between each connecting rod 43 and the winding wheel 42. The rotation of the winding wheel 42 can wind up the pull rope 44.

[0030] like Figure 1 and Figure 4 As shown, the rotating mechanism 5 includes a connecting plate 51, a first contact rod 52, a rotating shell 53, and a fixed plate 54. The connecting plate 51 is bolted to the upper part of the bracket 1. The first contact rod 52 is placed on the upper part of the connecting plate 51. The rotating shell 53 is connected to the outside of the first contact rod 52. The fixed plate 54 is rotatably connected to the upper part of the rotating shell 53.

[0031] like Figure 1 and Figure 5As shown, the lowering mechanism 6 includes a first gear 61, a nut 62, a screw 63, a connecting frame 64, and a second gear 65. The first gear 61 is connected to the output shaft of the first motor 41 by a key. The first gear 61 is located on the upper side of the winding wheel 42. Nuts 62 are bolted to both sides of the lower part of the first contact rod 52. The nuts 62 are in contact with the rotating housing 53. Screws 63 are threadedly connected to both nuts 62. The connecting frame 64 is connected to the bottom of the connecting plate 51. The middle part of the screws 63 is rotatably connected to the connecting plate 51 and the connecting frame 64. The upper part of both screws 63 is connected to the adjacent connecting frame 64 through bearings. The lower part of both screws 63 is connected to the second gear 65 by a key. The first gear 61 meshes with the two second gears 65.

[0032] When the operator needs to use this device, the fixing plate 54 can be installed on the ceiling, and then the LED lamp 2 can be turned on to emit light. The first focusing plate 3 can concentrate the light emitted by the LED lamp 2. When it is necessary to adjust the angle of the first focusing plate 3 in concentrating the light, the first motor 41 can be turned on, so that the output shaft of the first motor 41 drives the winding wheel 42 to rotate, thereby causing the pull rope 44 to be wound on the winding wheel 42, so that the first focusing plate 3 rotates upward. When the first focusing plate 3 reaches the predetermined position, the first motor 41 can be turned off. When motor 41 stops operating, the output shaft of the first motor 41 rotates, driving the first gear 61 to rotate. This causes the two second gears 65 to mesh with the first gear 61, driving the screw 63 to rotate. The screw 63 then moves the connecting plate 51, bracket 1, LED lamp 2, and first focusing plate 3 downwards via the connecting frame 64, disengaging the first contact rod 52 from the connecting plate 51. When the first motor 41 stops driving the first gear 61 to rotate, the two second gears 65 stop driving the screw 63 to rotate, preventing the LED lamp 2 and the first focusing plate 3 from moving downwards. When plate 3 stops, it also reaches the predetermined height, thus enabling the LED lamp 2 and the first focusing plate 3, which have reached the predetermined height and predetermined illumination angle, to cooperate with each other, facilitating the operation of the device. When the operator no longer needs to use the device, the LED lamp 2 can be turned off, and then the output shaft of the first motor 41 can be controlled to drive the winding wheel 42 and the first gear 61 to rotate in the opposite direction. While the winding wheel 42 is rotating in the opposite direction, the pull rope 44 is gradually released, causing the first focusing plate 3 to rotate downwards and reset. At the same time as the first gear 61 is rotating in the opposite direction, the two second gears 65 mesh with the first gear 61, driving the screw 63 to rotate in the opposite direction. The screw 63 moves upward and resets the connecting plate 51, bracket 1, LED lamp 2, and first focusing plate 3 via the connecting frame 64. Once the LED lamp 2 and first focusing plate 3 are reset, the first motor 41 can be turned off, stopping its operation. Thus, by starting the first motor 41, the first focusing plate 3 can be rotated upward, facilitating the adjustment of the angle at which the first focusing plate 3 concentrates light. Through the meshing of the first gear 61 and the second gear 65, the LED lamp 2 and the first focusing plate 3 can be moved downward, thereby adjusting the illumination height of the LED lamp 2 and the focusing plate.

[0033] Example 2

[0034] like Figure 1 and Figure 6As shown, based on Embodiment 1, an extension mechanism 7 is also included. The extension mechanism 7 includes a sliding rod 71, a sliding block 72, and a second concentrating plate 73. There are four sets of sliding rods 71, with two sliding rods 71 ​​in each set. A set of sliding rods 71 ​​is welded to the top of each first concentrating plate 3. A sliding block 72 is slidably connected to the two sliding rods 71 ​​in each set. A second concentrating plate 73 is bolted between each pair of adjacent sliding blocks 72. The second concentrating plate 73 is used to concentrate and focus the light. The second concentrating plate 73 is slidably connected to the first concentrating plate 3.

[0035] like Figure 1 and Figure 7 As shown, it also includes a pushing mechanism 8, which includes a limit frame 81, a second contact rod 82, and an elastic element 83. There are four sets of limit frames 81, with two limit frames 81 in each set. Four sets of limit frames 81 are evenly spaced welded to the lower part of the bracket 1. Each set of limit frames 81 is located on the outer side of the adjacent first focusing plate 3. Two second contact rods 82 are welded to the top of each second focusing plate 73. The second contact rods 82 can rotate upward to contact the adjacent limit frames 81. An elastic element 83 is sleeved on each of the two sliding rods 71 ​​in each set. The two ends of the elastic element 83 are connected to the sliding rod 71 and the sliding block 72, respectively.

[0036] As the first concentrating plate 3 rotates upward, it drives the second concentrating plate 73 and the second contact rod 82 to rotate, causing the second contact rod 82 to contact the U-shaped limiting frame 81 and drive the second concentrating plate 73 to move outward. This compresses the elastic element 83. When the second concentrating plate 73 moves outward, it cooperates with the first concentrating plate 3 to extend the focusing angle of the light. As the first concentrating plate 3 rotates downward, it drives the second concentrating plate 73 and the second contact rod 82 to rotate downward, causing the second contact rod 82 to contact the U-shaped limiting frame 81. Then, the elastic element 83 drives the second concentrating plate 73 to move inward and reset. In this way, the contact between the second contact rod 82 and the limiting frame 81 drives the second concentrating plate 73 to move outward, thereby achieving the effect of extending the focusing angle of the light.

[0037] like Figure 1 and Figure 8 As shown, it also includes a rotating mechanism 9, which includes a second motor 91, a third gear 92 and a rotating frame 93. The second motor 91 is bolted to the upper front side of the rotating housing 53. The third gear 92 is connected to the output shaft of the second motor 91 by a key. The rotating frame 93 is bolted to the upper part of the rotating housing 53. The rotating frame 93 can rotate to contact the fixed plate 54. The rotating frame 93 has evenly spaced toothed holes 94, and the third gear 92 meshes with the toothed holes 94.

[0038] When it is necessary to adjust the range of concentrated irradiation of the first concentrating plate 3 and the second concentrating plate 73, the second motor 91 can be started, so that the output shaft of the second motor 91 drives the third gear 92 to rotate, and then the third gear 92 meshes with the tooth hole 94 to drive the rotating frame 93, the first contact rod 52, the rotating shell 53, the LED lamp 2, the first concentrating plate 3 and the second concentrating plate 73 to rotate. When the first concentrating plate 3 and the second concentrating plate 73 are adjusted to the predetermined range of concentrated irradiation, the second motor 91 can be turned off, so that the second motor 91 stops running. In this way, by starting the second motor 91, the LED lamp 2, the first concentrating plate 3 and the second concentrating plate 73 can be rotated, thereby achieving the purpose of adjusting the range of concentrated irradiation of the first concentrating plate 3 and the second concentrating plate 73.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
