Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and particularly to an embedded LED corn lamp. Background Art

[0002] Due to its high efficiency and energy-saving characteristics, LED lighting technology has been widely used in recent years, especially favored in the lighting field. As an important type of LED lighting product, the LED energy-saving corn lamp has the characteristics of multi-lamp bead design, high brightness, low power consumption, etc., and is widely used in commercial lighting, industrial lighting, indoor lighting and other fields.

[0003] At present, between each lamp board of traditional LED corn lamps, conduction is achieved through externally added wires. The externally added wires need to be welded to the corresponding positions using a soldering station, and the connection between the drive circuit and the lamp board is also achieved through welding of externally added wires. This connection method makes the assembly of LED lamps cumbersome and labor-intensive, and the damage of some LED lamps will affect the light-emitting effect of the entire LED bulb, resulting in a decrease in the brightness of the LED bulb. In the case where some LEDs can still work, if users repair it by themselves, they need to replace the LED lamp board, and the replacement of the LED lamp board requires the help of a soldering station. Most users do not have this tool, so users either endure the low light-emitting brightness of the bulb or discard the LED bulb. At present, the assembly of LED bulbs with this connection method is cumbersome, consumes a lot of manpower, and it is not easy to repair the bulbs later, thus causing serious waste of resources;

[0004] For example, the existing Chinese patent document CN201220231575.0 discloses an LED corn lamp. This patent provides a patch type LED corn lamp, but its installation, disassembly and repair are very complicated. At the same time, the existing Chinese patent document CN201310444095.1 discloses an LED corn lamp that is easy to assemble. In the lamp design described in this patent, the lamp cover and the lamp body are connected through a card slot located at the top, and the LED lamp board is designed to be inserted into the card slot outside the lamp body for easy installation and fixation. However, in the actual application process, when a large number of LED lamp boards need to be installed, the operation efficiency of fixing each LED lamp board to the card slot one by one is quite low. At the same time, when multiple LED lamp boards need to be replaced during use, these LED lamp boards also need to be disassembled one by one. This process is not only time-consuming but also cumbersome. Therefore, this design has certain limitations in actual use, especially in the occasion where LED lamp boards need to be frequently replaced, and this limitation will be more obvious.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: Please refer to Figures 1-3 and Figure 12 , an embedded LED corn lamp shown in the figure includes a lamp body 1 and a lamp cover 2. A plurality of grooves 101 are evenly formed on the outer side of the lamp body 1, and an LED lamp board 3 is embedded in the grooves 101. A cavity is provided inside the lamp cover 2. The LED lamp board 3 can be accommodated through the grooves 101 for installation, and the cavity is convenient for the installation of the main structure;

[0036] It further includes: multiple groups of fixing units 4 installed in the cavity. The multiple groups of fixing units 4 are distributed in a circular array. The fixing units 4 are used to quickly connect the multiple groups of LED lamp boards 3, the lamp body 1, and the lamp cover 2. A linkage unit 5 for synchronously rotating the multiple groups of fixing units 4 is also provided inside the lamp cover 2. Under the action of the designed fixing units 4 and the linkage unit 5, the multiple groups of LED lamp boards 3 and the lamp body 1 can be quickly installed. When in use, it is not necessary to fix each LED lamp board 3 to the card slot one by one to achieve the installation of the lamp body 1, the lamp cover 2, and the LED. Moreover, the fixing effect is better by using the thread positioning method, making it relatively quick to disassemble the LED lamp board 3;

[0037] A heat exhaust pipe 8 fixedly inserted on the lamp body 1. A heat dissipation unit 6 is fixedly installed on one side of the lamp cover 2. A connecting piece 7 is provided between the heat dissipation unit 6 and the heat exhaust pipe 8. The heat exhaust pipe 8 is of a corrugated pipe structure. Through the designed heat dissipation unit 6, the heat generated inside the lamp body 1 can be quickly discharged, achieving the effect of active heat dissipation. Compared with the existing heat dissipation method using heat dissipation strips, the heat dissipation effect of the corn lamp is significantly improved;

[0038] A synchronous reduction unit 12 installed at the input end of the linkage unit 5. One end of the heat dissipation unit 6 is fixedly connected to the output end of the synchronous reduction unit 12. By driving the synchronous reduction unit 12 through the heat dissipation unit 6, on the one hand, the linkage unit 5 can be rotated, thus facilitating the automatic installation and disassembly of the fixing units 4. On the other hand, it can drive the heat dissipation unit 6 to open the bottom of the lamp body 1 during heat dissipation, further improving the heat dissipation effect.

[0039] Further, referring to Figures 3-4 , the fixing unit 4 includes a roller bearing 41, a mounting stud 42, a sleeve 43, and a sliding member 44. The inner ring of the roller bearing 41 is fixed to the inner wall of the lamp cover 2, and the outer ring of the roller bearing 41 rotates freely. The mounting stud 42 is in transitional fit with the inner ring of the roller bearing 41. The mounting stud 42 is threadedly connected to the lamp cover 2 through a threaded hole. The mounting stud 42 is also threadedly connected to the lamp body 1 and the LED lamp board 3 through preset threaded holes. The sleeve 43 is fixedly connected to the outer ring of the roller bearing 41. The sliding member 44 is fixedly connected to one end of the mounting stud 42. The output end of the linkage unit 5 is in transmission connection with the sleeve 43.

[0040] Among them, referring to Figure 4, To ensure that the installation stud 42 can also move as the sleeve 43 rotates, the sliding member 44 includes an annular block 441 and a trapezoidal slider 442. A circular hole 443 is provided in the middle of the sleeve 43, and a plurality of sliding grooves 444 are evenly distributed on the inner wall of the circular hole 443. The trapezoidal slider 442 is fixed to the outer side of the annular block 441, and the trapezoidal slider 442 is slidably connected to the sliding groove 444. A thrust spring 45 is fixed to the inner wall of the lamp cover 2, and one end of the thrust spring 45 is elastically in contact with the end of the annular block 441.

[0041] Principle of installing the LED lamp board 3 and the lamp cover 2: Align one end of the installation stud 42 with the threaded holes on the lamp body 1 and the LED lamp board 3, and then drive the plurality of sleeves 43 to rotate synchronously by the output end of the linkage unit 5, thereby driving the plurality of annular blocks 441 to rotate synchronously. The annular block 441 drives the installation stud 42 to rotate. Since the annular block 441 and the sleeve 43 are slidably connected through the trapezoidal slider 442 and the sliding groove 444, the annular block 441 will also drive the installation stud 42 to move within the sleeve 43, thereby driving the installation stud 42 to screw into the threaded holes on the LED lamp board 3 and the lamp body 1, realizing the threaded connection between the lamp cover 2, the lamp body 1, and the LED lamp board 3. Since the plurality of installation studs 42 rotate simultaneously, compared with the current operation method of fixing the LED lamp board 3 to the card slot one by one, the efficiency is greatly improved, and the fixing effect is better by using the threaded positioning method, making it quicker to disassemble the LED lamp board 3.

[0042] It should be noted that: Please refer to Figure 3 , During the movement of the installation stud 42, since the thrust spring 45 is fixed to the inner wall of the lamp cover 2, the elastic thrust generated by the thrust spring 45 has a thrust effect in the axial direction of the installation stud 42, ensuring that the installation stud 42 has sufficient pressure when contacting the threaded hole, thereby increasing the friction force during contact and preventing the problem of idling when the installation stud 42 rotates.

[0043] Furthermore, refer to Figure 5 , To be able to rotate multiple groups of fixing units 4 at one time, the linkage unit 5 includes a fixed cylinder 51, an external gear ring 52, a transmission gear 53, and a driving member 54. The fixed cylinder 51 is fixed at the center inside the lamp cover 2, the external gear ring 52 is rotatably connected to the outside of the fixed cylinder 51 through a bearing, a plurality of groups of transmission gears 53 are evenly distributed, and the plurality of groups of transmission gears 53 are all meshed with the external gear ring 52. The transmission gear 53 is fixedly sleeved with the sleeve 43, and the output end of the driving member 54 is in transmission connection with the external gear ring 52.

[0044] Among them, refer to Figure 6, for the convenience of personnel to rotate the external gear ring 52, the driving member 54 includes a driving gear 541 and a driving rod 542. The driving rod 542 is inserted through the lamp cover 2 and is rotatably connected to the lamp cover 2 through a bearing. The driving gear 541 is inside the lamp cover 2 and is fixedly sleeved with the driving rod 542. The external gear ring 52 is meshed with the driving gear 541. One end of the driving rod 542 extending outside the lamp cover 2 is fixedly connected to the output end of the synchronous reduction unit 12.

[0045] The principle of the linkage unit 5 driving multiple sleeves 43 to move in a linkage manner: During installation, the input power of the heat dissipation unit 6 can be used to rotate the driving rod 542. The driving rod 542 drives the driving gear 541 to rotate, and the driving gear 541 drives the external gear ring 52 to rotate, thereby driving all the transmission gears 53 to rotate together. Finally, multiple groups of sleeves 43 can rotate synchronously, ensuring that multiple mounting studs 42 move together.

[0046] It should be noted that: Please refer to Figure 9 , before installing the LED lamp board 3, a diamond-shaped groove 10 is formed at one end of the LED lamp board 3 away from the fixing unit 4. A diamond-shaped limiting post 11 adapted to the diamond-shaped groove 10 is fixed on the inner wall of the groove 101. The LED lamp board 3 is pushed into the groove 101, and the diamond-shaped groove 10 at one end of the LED lamp board 3 is docked with the diamond-shaped limiting post 11 for preliminary positioning of the LED lamp board 3, so as to facilitate further limiting of the LED lamp board 3;

[0047] Embodiment 2: Please refer to Figure 7 and Figure 13 , this embodiment further explains Embodiment 1, and the difference lies in optimizing the heat dissipation method of the LED corn lamp.

[0048] Specifically, the heat dissipation unit 6 includes a sealed piston box 61, a sealed bearing 62, a reciprocating lead screw 63, a sliding seat 64 and a piston plate 65. The sealed piston box 61 is fixedly connected to the bottom of the lamp cover 2. The sealed bearing 62 is fitted and installed at the left and right ends of the sealed piston box 61. The end of the reciprocating lead screw 63 is fixedly sleeved with the inner ring of the sealed bearing 62. The sliding seat 64 is sleeved outside the reciprocating lead screw 63. The piston plate 65 is fixedly installed on the outer ring of the sliding seat 64. The piston plate 65 is slidably connected to the sealed piston box 61. One end of the reciprocating lead screw 63 is fixedly connected to a driving motor 66 through a coupling. One side of the driving motor 66 is fixed to the sealed piston box 61 through a fixing plate. A first intake check valve 67 and a first exhaust check valve 68 are respectively fitted and installed on the side of the sealed piston box 61 away from the driving motor 66. One end of the first intake check valve 67 is connected to a first intake pipe 69. The first intake pipe 69 is fixed to the exhaust heat pipe 8 through a connecting member 7. The first intake pipe 69 is of a corrugated pipe structure. One end of the first exhaust check valve 68 is connected to a first exhaust pipe 610. The air outlet end of the first exhaust pipe 610 blows air towards the synchronous deceleration unit 12. A cleaning component 9 is provided on the outer side of the lamp cover 2. The input end of the synchronous deceleration unit 12 is fixedly connected to one end of the reciprocating lead screw 63.

[0049] The principle of actively dissipating heat from the inside of the lamp body 1: By starting the driving motor 66 to rotate, the reciprocating lead screw 63 is driven to rotate inside the sealed piston box 61 through the sealed bearing 62, and then the sliding seat 64 and the piston plate 65 are driven to reciprocate left and right and cooperate with the sealed piston box 61 to perform piston motion, which is beneficial to generating negative pressure inside the sealed piston box 61, and the hot air flow above the lamp body 1 is extracted through the first intake check valve 67, the first intake pipe 69 and the exhaust heat pipe 8. The extracted hot air flow is transported to the cleaning component 9 through the first exhaust check valve 68 and the first exhaust pipe 610, so as to automatically and quickly discharge the accumulated hot air flow above the lamp body 1 actively, increasing the convection rate of the lamp body 1 and the external air and improving the heat dissipation efficiency of the LED corn lamp.

[0050] Meanwhile, referring to Figure 10 , the connecting member 7 includes an external thread block 71 and a rotating block 72. The external thread block 71 is fixed to the end of the first intake pipe 69 away from the sealed piston box 61. The rotating block 72 is threadedly connected to the outside of the external thread block 71. The rotating block 72 is rotatably connected to the top end of the exhaust heat pipe 8. Before assembly, the external thread block 71 at the end of the intake pipe is inserted into the exhaust heat pipe 8, and then the rotating block 72 is manually rotated to thread the external thread block 71 into the moving block, so that the exhaust heat pipe 8 and the intake pipe are fixedly connected. In this way, when disassembling the lamp cover 2, the lamp body 1 and the LED lamp board 3, the fixation between the heat dissipation unit 6 and the exhaust heat pipe 8 can be quickly released.

[0051] Embodiment 3: Please refer to Figure 8 and Figure 14, This embodiment further illustrates other embodiments. The difference lies in adding a cleaning component 9, which effectively cleans the dirt on the outer side of the LED lamp board 3.

[0052] Specifically, the cleaning component 9 includes an annular air delivery pipe 91 and a shunt pipe 92. The annular air delivery pipe 91 is fixedly sleeved on the outer side of the lamp cover 2. One end of the shunt pipe 92 is fixed to the annular air delivery pipe 91. The number of shunt pipes 92 is equal to the number of LED lamp boards 3. A plurality of air jet nozzles 93 are evenly distributed on one side of the shunt pipe 92. The air jet nozzles 93 are arranged obliquely facing the lamp beads of the LED lamp board 3. A second air outlet pipe 94 is fixed between the annular air delivery pipe 91 and the sealing piston box 61. A second air intake one-way valve 95 and a second air outlet one-way valve 96 are respectively embedded and installed on one side of the sealing piston box 61 close to the driving motor 66. One end of the second air outlet pipe 94 is connected to one end of the second air outlet one-way valve 96. One end of the second air intake one-way valve 95 is connected to a second air intake pipe 97.

[0053] Specifically, when the piston plate 65 moves from left to right, cold air is inhaled into the left space of the piston plate 65 through the second air intake pipe 97. When the piston plate 65 moves from right to left, the inhaled cold air enters the annular air delivery pipe 91 and the shunt pipe 92 respectively through the second air outlet pipe 94, and finally is discharged from a plurality of air jet nozzles 93. As a result, the air jet nozzles 93 at multiple positions blow air outwards in sequence, blowing and cleaning the dust on the outer side of the LED lamp board 3, which can, to a certain extent, remove the dust and dirt on the surface of the lamp board, maintain the cleanliness of the LED lamp board 3, thereby extending its service life and preventing foreign objects from adhering.

[0054] Embodiment 4: Please refer to Figure 7 and Figure 11 , This embodiment further illustrates other embodiments. The difference lies in adding a synchronous deceleration unit 12, which can further optimize the heat dissipation mode of the LED corn lamp.

[0055] Specifically, the synchronous deceleration unit 12 includes a worm gear 121, a worm 122, a transmission rod 123, a first reduction gear 124, a second reduction gear 125, and a third reduction gear 126. The worm gear 121 is meshed and connected with the worm 122. The worm 122 is fixedly connected to the end of the reciprocating lead screw 63 away from the driving motor 66. Both the worm gear 121 and the first reduction gear 124 are fixedly sleeved on the transmission rod 123. One end of the transmission rod 123 is rotatably connected to the lamp cover 2 through a bearing. The second reduction gear 125 is meshed and connected with the first reduction gear 124 and the third reduction gear 126 respectively. One end of the central axis of the second reduction gear 125 is rotatably connected to the lamp cover 2 through a bearing. The third reduction gear 126 is fixedly sleeved on the driving rod 542. The pitch circle diameters of the first reduction gear 124, the second reduction gear 125, and the third reduction gear 126 are arranged in an increasing order.

[0056] Specifically, when the driving motor 66 drives the reciprocating lead screw 63 to rotate, it will also drive the worm 122 to rotate. The worm 122 will drive the worm wheel 121 to rotate, and then drive three sets of reduction gears to transmit power through the transmission rod 123. The three sets of reduction gears will gradually reduce the rotational speed output by the reciprocating lead screw 63. That is, after the reciprocating lead screw 63 rotates multiple circles, the third reduction gear 126 just rotates 2 - 3 circles, and the driving rod 542 also rotates 2 - 3 circles. Eventually, it will drive the mounting stud 42 to thread out a lead distance of 2 - 3 circles, and one side of the lamp cover 2 will move a small distance away from the lamp body 1, so that a certain gap is generated between the lamp cover 2 and the lamp body 1. After the active heat dissipation ends, that is, when the driving motor 66 stops rotating, the lamp body 1 can maintain a certain opening size with the outside world. At this time, the heat generated by the driving circuit below the lamp body 1 can also automatically discharge from the gap, which can further accelerate the air exchange rate below the lamp body 1 and further improve the heat dissipation efficiency of the entire corn lamp.

[0057] It should be noted that a dust-proof net (not labeled in the figure) is also provided at the bottom of the lamp body 1, so that the air entering after the bottom of the lamp body 1 is opened can remain pure and reduce the dust from entering the inside of the lamp body 1 again.

[0058] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0059] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
