Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp beads, in particular to an LED lamp bead with adjustable illumination. Background Art

[0002] LED lamp beads are commonly used lighting products in life, and high-power LED lamp beads are a type of LED lamp beads. Compared with low-power LED lamp beads, high-power LED lamp beads have higher power and brighter brightness. However, the lighting range of existing LED lamp beads is fixed and cannot be effectively adjusted according to needs.

[0003] For example, the patent with announcement number CN218883700U discloses an LED lamp bead with adjustable lighting. The light emitted by the LED lamp bead body passes through a small concave lens and a large concave lens and then diverges outward, increasing the illumination range of the LED lamp bead body light, thereby having the advantage of being able to adjust the lighting according to needs. However, it is inconvenient to adjust the lighting angle. When the lighting angle cannot be adjusted, the LED lamp bead will irradiate part of the light to areas that do not need lighting, resulting in energy waste. This waste is particularly obvious in scenes where precise control of the lighting range is required. In view of this, an LED lamp bead with adjustable lighting is designed. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides an LED lamp bead with adjustable lighting, which solves the problem in the related technology that it is inconvenient to adjust the lighting angle. When the lighting angle cannot be adjusted, the LED lamp bead will irradiate part of the light to the area that does not need lighting, resulting in energy waste. This waste is particularly obvious in scenes where precise control of the lighting range is required.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an LED lamp bead with adjustable illumination, comprising a mounting base, the mounting base being provided with a plurality of mounting grooves, a fixing plate being fixedly connected to the interior of the mounting grooves, and a first clamping ring being fixedly connected to the front surface of the fixing plate;

[0006] A pull rod is movably connected between the fixing plate and the first clamping ring. One end of the pull rod is fixedly connected to the limit plate. A compression spring is sleeved on the outer surface of the pull rod. The other end of the pull rod is fixedly sleeved with a second clamping ring. The second clamping ring is clamped on the first clamping ring.

[0007] The other end of the pull rod is fixedly sleeved with a fixing block, and the outer side of the fixing block is connected to an LED lamp bead.

[0008] Furthermore, one end of the compression spring abuts against the limiting plate, and the other end of the compression spring abuts against the fixing plate.

[0009] Furthermore, the front surface of the first clamping ring is provided with raised blocks at equal distances around the circumference, and the opposite surface of the second clamping ring and the first clamping ring is provided with clamping grooves at equal distances around the circumference, and the raised blocks are clamped inside the clamping grooves.

[0010] Furthermore, the protruding block and the slot have the same shape, and the protruding block and the slot are in a triangular shape.

[0011] Furthermore, support plates are fixedly connected to both sides of the fixing block, and the LED lamp beads are installed on the support plates.

[0012] Furthermore, the back surface of the support plate abuts against the front surface of the mounting seat.

[0013] Furthermore, a locking sleeve is provided on the outer surface of the pull rod, and the locking sleeve is fixedly connected between the second retaining ring and the fixed block. A threaded hole is provided on the locking sleeve, and a locking bolt is connected to the internal thread of the threaded hole. One end of the locking bolt abuts against the outer surface of the pull rod.

[0014] By means of the above technical solution, the present invention provides an LED lamp bead with adjustable illumination, which has at least the following beneficial effects:

[0015] 1. When the angle of the adjustable lighting LED lamp bead needs to be adjusted, you only need to pull the fixed block outward to overcome the elastic force of the compression spring, pull the pull rod outward and rotate it to disengage the second clamping ring from the lock of the first clamping ring. The angle of the LED lamp bead can be adjusted, which solves the problem that the lighting angle of traditional LED lamp beads cannot be adjusted. The illumination angle of the LED lamp bead can be freely adjusted according to actual lighting needs, achieving more accurate and flexible lighting effects.

[0016] 2. The triangular protrusion of the LED lamp bead with adjustable lighting matches the shape of the card slot, which can achieve precise card connection and positioning, ensuring the stability of the LED lamp bead 10 after adjusting the angle, and avoiding the lighting effect affected by looseness or misalignment.

[0017] 3. For this adjustable-light LED lamp, place the second retaining ring, locking sleeve, and fixing block on the pull rod. Then, screw the locking bolt into the threaded hole on the locking sleeve, with one end of the locking bolt resting against the outer surface of the pull rod. At this point, the locking sleeve is firmly fixed to the pull rod, which in turn secures the second retaining ring and fixing block to the pull rod. Install the LED lamp on the support plate to complete the assembly of the entire LED lamp assembly. If the LED lamp assembly needs to be disassembled or maintained, simply loosen the locking bolt and remove the fixing block, locking sleeve, and second retaining ring from the pull rod.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5 , an LED lamp bead with adjustable lighting, including a mounting base 1, a plurality of fixing ears 13 fixedly connected to the mounting base 1, a plurality of mounting slots 2 provided on the mounting base 1, a fixing plate 3 fixedly connected to the inside of the mounting slot 2, a first clamping ring 4 fixedly connected to the front of the fixing plate 3; a pull rod 5 movably connected in the middle of the fixing plate 3 and the first clamping ring 4, one end of the pull rod 5 is fixedly connected to a limiting plate 6, the outer surface of the pull rod 5 is sleeved with a compression spring 7, one end of the compression spring 7 abuts against the limiting plate 6, the other end of the compression spring 7 abuts against the fixing plate 3, the other end of the pull rod 5 is fixedly sleeved with a second clamping ring 8, and the second clamping ring 8 is clamped on the first clamping ring 4; the other end of the pull rod 5 is fixedly sleeved with a fixing block 9, and the outer side of the fixing block 9 is connected to the LED lamp bead 10. When the angle needs to be adjusted, just pull the fixing block 9 outward with force to overcome the elastic force of the compression spring 7, pull the pull rod 5 outward and rotate it to disengage the second clamping ring 8 from the lock of the first clamping ring 4, and then the angle of the LED lamp bead 10 can be adjusted. This solves the problem that the lighting angle of the traditional LED lamp bead 10 cannot be adjusted. The illumination angle of the LED lamp bead can be freely adjusted according to actual lighting needs to achieve more precise and flexible lighting effects.

[0027] The front of the first snap ring 4 is provided with raised blocks at equal intervals around the circumference. The second snap ring 8, facing the first snap ring 4, is provided with slots at equal intervals around the circumference. The raised blocks snap into place within the slots. The raised blocks and the slots have the same shape, forming a triangular shape. The triangular shape of the raised blocks matches the shape of the slots, enabling precise engagement and positioning, ensuring the stability of the LED lamp bead 10 after angle adjustment, and preventing looseness or misalignment that could affect the lighting effect.

[0028] Both sides of the fixing block 9 are fixedly connected with support plates 11, and the LED lamp beads 10 are installed on the support plates 11. The back of the support plate 11 is against the front of the mounting base 1.

[0029] The outer surface of the tie rod 5 is covered with a locking sleeve 12. This sleeve is an annular or tubular structure with an inner diameter larger than the outer diameter of the tie rod 5, allowing it to slide over the tie rod 5. The locking sleeve 12 is fixedly connected between the second retaining ring 8 and the fixing block 9. A threaded hole is provided through the locking sleeve 12, and a locking bolt is threadedly connected to the inner threaded hole. One end of the locking bolt abuts the outer surface of the tie rod 5. The second retaining ring 8, locking sleeve 12, and fixing block 9 are placed over the tie rod 5. Then, the locking bolt is screwed into the threaded hole in the locking sleeve 12, with one end of the locking bolt abutting the outer surface of the tie rod 5. This secures the locking sleeve 12 to the tie rod 5, thereby securing the second retaining ring 8 and fixing block 9 to the tie rod 5. The LED lamp 10 is then mounted on the support plate 11, completing the assembly of the LED lamp 10. To disassemble the LED lamp 10 assembly or perform maintenance, simply loosen the locking bolt and remove the fixing block 9, locking sleeve 12, and second retaining ring 8 from the tie rod 5.

[0030] Working principle: When in use, the compression spring 7 is in a naturally extended state when not compressed, exerting a certain thrust on the limit plate 6, so that the second clamping ring 8 is clamped on the first clamping ring 4;

[0031] When the angle needs to be adjusted, just pull the fixed block 9 outward and rotate it, and pull the limit plate 6 outward through the pull rod 5. The compression spring 7 is compressed, and the second clamping ring 8 is released from the lock of the first clamping ring 4, and the angle of the LED lamp bead 10 can be adjusted.

[0032] After adjusting the angle of the LED lamp bead 10, loosen the fixing block 9, and the elastic force of the compression spring 7 applies a certain thrust to the limit plate 6. The second clamping ring 8 is re-inserted into the first clamping ring 4, and the support plate 11 abuts against the front of the mounting base 1, thereby changing the irradiation angle of the light emitted by the LED lamp bead 10. The lighting direction of the LED lamp bead 10 can be flexibly adjusted as needed to adapt to different lighting needs.

[0033] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
