Description

Technical Field

[0001] The invention relates to the technical field of lamps, and in particular to a built-in LED corn lamp. Background Art

[0002] LED lighting technology has been widely used in recent years due to its high efficiency and energy saving characteristics, especially in the field of lighting. As an important type of LED lighting products, LED energy-saving corn lamps have the characteristics of multi-bead design, high brightness, and low power consumption, and are widely used in commercial lighting, industrial lighting, and indoor lighting.

[0003] At present, the light boards of traditional LED corn lamps are connected by additional wires. The additional wires need to be welded to the corresponding positions using an electric soldering station, and the connection between the driving circuit and the light board is also achieved by welding additional wires. This connection method makes the assembly of LED lamps cumbersome and labor-intensive, and the damage of some LED lamps will affect the luminous effect of the entire LED bulb, and the brightness of the LED bulb will be reduced. If some LEDs can still work, if the user needs to replace the LED light board for self-repair, the replacement of the LED light board requires the help of an electric soldering station, and most users do not have this tool. Users either have to endure the low brightness of the bulb or discard the LED bulb. At present, the assembly of LED bulbs with this connection method is cumbersome and consumes a lot of manpower. In addition, it is not easy to repair the bulbs in the later stage, resulting in a serious waste of resources; For example, the existing Chinese patent document CN201220231575.0 discloses an LED corn lamp, which provides a patch-type LED corn lamp, but its installation, disassembly and maintenance 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 the patent, the lamp cover and the lamp body are connected through a card slot located at the top, and the LED light board is designed to be inserted into the card slot outside the lamp body for easy installation and fixation. However, in actual application, when a large number of LED light boards need to be installed, the efficiency of fixing the LED light boards to the card slots one by one is quite low. At the same time, when multiple LED light boards need to be replaced during use, these LED light 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 situations where LED light boards need to be replaced frequently, this limitation will be more obvious.

DETAILED DESCRIPTION

[0019] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-Figure 3 and Fig.12 The 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. 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 facilitates the installation of the main structure. It also includes: multiple groups of fixing units 4 installed in the cavity, the multiple groups of fixing units 4 are distributed in a ring array, the fixing units 4 are used to quickly connect multiple groups of LED light panels 3 with the lamp body 1 and the lamp cover 2, and the lamp cover 2 is also provided with a linkage unit 5 for synchronously rotating the multiple groups of fixing units 4. Through the designed fixing units 4 and the linkage unit 5, the multiple groups of LED light panels 3 and the lamp body 1 can be quickly installed. When in use, it is not necessary to fix the LED light panels 3 with the card slots one by one to achieve the installation of the lamp body 1, the lamp cover 2 and the LED, and the fixing effect is better by using the threaded positioning method, so that it is faster to remove the LED light panel 3; A heat dissipation pipe 8 is fixedly plugged into the lamp body 1, and 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 dissipation pipe 8. The heat dissipation pipe 8 is a corrugated pipe structure. The designed heat dissipation unit 6 can quickly discharge the heat generated inside the lamp body 1, and play an active heat dissipation effect. Compared with the existing heat dissipation method using heat dissipation strips, the heat dissipation effect of the corn lamp is significantly improved; The synchronous deceleration unit 12 is installed at the input end of the linkage unit 5, and one end of the heat dissipation unit 6 is fixedly connected to the output end of the synchronous deceleration unit 12. The synchronous deceleration unit 12 is driven by the heat dissipation unit 6. On the one hand, the linkage unit 5 can be rotated, thereby facilitating the automatic installation and disassembly of the fixing unit 4. On the other hand, the heat dissipation unit 6 can be linked to open the bottom of the lamp body 1 during heat dissipation, thereby further improving the heat dissipation effect.

[0021] For further information, see Figure 3-Figure 4The 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 transitionally matched 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 a preset threaded hole. 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 transmission-connected to the sleeve 43.

[0022] Among them, see Figure 4 In order to ensure that the mounting stud 42 can move with the rotation of the sleeve 43, the sliding member 44 includes an annular block 441 and a trapezoidal slider 442. A circular hole 443 is opened in the middle of the sleeve 43, and a plurality of sliding grooves 444 are evenly distributed on the hole 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.

[0023] The principle of installing the LED lamp board 3 and the lamp cover 2 is as follows: align one end of the mounting stud 42 with the threaded holes on the lamp body 1 and the LED lamp board 3, and then the output end of the linkage unit 5 drives multiple sleeves 43 to rotate synchronously, and then drives multiple annular blocks 441 to rotate synchronously, and the annular block 441 drives the mounting 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 mounting stud 42 to move in the sleeve 43, and then drive the mounting stud 42 to screw into the threaded holes on the LED lamp board 3 and the lamp body 1, thereby realizing the threaded connection between the lamp cover 2 and the lamp body 1 and the LED lamp board 3. Since multiple mounting studs 42 rotate at the same time, the efficiency is greatly improved compared with the current operation method of fixing the LED lamp board 3 to the slot one by one, and the fixing effect is better by using the threaded positioning method, so that it is faster to disassemble the LED lamp board 3.

[0024] Please note: Please refer to Figure 3 During the movement of the mounting 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 mounting stud 42, ensuring that the mounting stud 42 has sufficient pressure when contacting the threaded hole, thereby increasing the friction during contact and preventing the mounting stud 42 from idling when rotating.

[0025] For further information, see Figure 5In order to rotate multiple groups of fixed units 4 at one time, the linkage unit 5 includes a fixed cylinder 51, an outer gear ring 52, a transmission gear 53 and a driving member 54. The fixed cylinder 51 is fixed at the inner center of the lamp cover 2, and the outer gear ring 52 is rotatably connected to the outer side of the fixed cylinder 51 through a bearing. There are multiple groups of transmission gears 53 evenly distributed, and the multiple groups of transmission gears 53 are all meshed and connected with the outer gear ring 52. The transmission gear 53 is fixedly sleeved with the sleeve 43, and the output end of the driving member 54 is transmission-connected to the outer gear ring 52.

[0026] Among them, see Figure 6 In order to facilitate personnel to rotate the outer gear ring 52, the driving member 54 includes a driving gear 541 and a driving rod 542. The driving rod 542 is inserted into 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 outer gear ring 52 is meshed with the driving gear 541. The 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.

[0027] The principle of the linkage unit 5 driving multiple sleeves 43 to be linked: during installation, the input power of the heat dissipation unit 6 can be used to rotate the drive rod 542, the drive rod 542 drives the drive gear 541 to rotate, the drive gear 541 drives the outer gear ring 52 to rotate, and then drives all the transmission gears 53 to rotate together, finally making multiple groups of sleeves 43 able to rotate synchronously, ensuring that multiple installation studs 42 move together.

[0028] Please note: Please refer to Fig. 9 Before installing the LED light board 3, a diamond groove 10 is provided at one end of the LED light board 3 away from the fixing unit 4, and a diamond limiting column 11 adapted to the diamond groove 10 is fixed on the inner wall of the groove 101. The LED light board 3 is pushed into the groove 101, and the diamond groove 10 at one end of the LED light board 3 is docked with the diamond limiting column 11 to perform preliminary positioning of the LED light board 3, thereby facilitating further positioning of the LED light board 3; Example 2: Please refer to Figure 7 and Fig.13 This embodiment further explains the first embodiment, and the difference lies in that the heat dissipation method of the LED corn lamp is optimized.

[0029] Specifically, the heat dissipation unit 6 includes a sealed piston box 61, a sealed bearing 62, a reciprocating screw rod 63, a slide 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 with the left and right ends of the sealed piston box 61, the end of the reciprocating screw rod 63 is fixedly sleeved with the inner ring of the sealed bearing 62, the slide seat 64 is sleeved on the outer side of the reciprocating screw rod 63, the piston plate 65 is fixedly installed with the outer ring of the slide seat 64, the piston plate 65 is slidably connected to the sealed piston box 61, one end of the reciprocating screw rod 63 is fixedly connected to the driving motor 66 through a coupling, and one side of the driving motor 66 is connected to the fixed plate through the fixed plate. The sealed piston box 61 is fixed, and a first air inlet check valve 67 and a first air outlet check valve 68 are respectively installed on one side of the sealed piston box 61 away from the driving motor 66. One end of the first air inlet check valve 67 is connected to a first air inlet pipe 69, and the first air inlet pipe 69 is fixed to the heat exhaust pipe 8 through a connecting piece 7. The first air inlet pipe 69 is a bellows structure, and one end of the first air outlet check valve 68 is connected to a first air outlet pipe 610. The air outlet end of the first air outlet pipe 610 blows air toward the synchronous reduction unit 12. A cleaning component 9 is provided on the outside of the lamp cover 2, and the input end of the synchronous reduction unit 12 is fixedly connected to one end of the reciprocating screw 63.

[0030] The principle of active heat dissipation inside the lamp body 1 is as follows: by starting the drive motor 66 to rotate, the reciprocating screw 63 is driven to rotate inside the sealed piston box 61 through the sealed bearing 62, and then the slide 64 and the piston plate 65 are driven to reciprocate left and right and cooperate with the sealed piston box 61 to perform piston movement, which is conducive 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 air inlet check valve 67, the first air inlet pipe 69 and the heat exhaust pipe 8. The extracted hot air flow is transported to the cleaning component 9 through the first air outlet check valve 68 and the first air outlet pipe 610, thereby automatically and actively discharging the hot air flow accumulated above the lamp body 1 quickly, increasing the convection rate between the lamp body 1 and the external air, and improving the heat dissipation efficiency of the LED corn lamp.

[0031] Also, see Fig.10 The connecting piece 7 includes an external thread block 71 and a rotating block 72. The external thread block 71 is fixed to one end of the first air inlet pipe 69 away from the sealing piston box 61. The rotating block 72 is connected to the outer thread of the external thread block 71. The rotating block 72 is rotatably connected to the top of the heat exhaust pipe 8. Before assembly, the external thread block 71 at the end of the air inlet pipe is inserted into the heat exhaust pipe 8, and then the rotating block 72 is manually rotated so that the external thread block 71 is screwed into the moving block, thereby fixing the heat exhaust pipe 8 and the air inlet pipe. In this way, when the lamp cover 2, the lamp body 1 and the LED lamp board 3 are disassembled, the heat dissipation unit 6 and the heat exhaust pipe 8 can be quickly released.

[0032] Example 3: Please refer to Figure 8 and Fig.14This embodiment further illustrates other embodiments, the difference being that a cleaning component 9 is added to effectively clean the dirt on the outside of the LED light board 3 .

[0033] Specifically, the cleaning component 9 includes an annular air pipe 91 and a diverter pipe 92. The annular air pipe 91 is fixedly sleeved on the outer side of the lamp cover 2. One end of the diverter pipe 92 is fixed to the annular air pipe 91. The number of diverter pipes 92 is equal to the number of LED lamp boards 3. Nozzles 93 are evenly distributed on one side of the diverter pipe 92. The nozzles 93 are arranged diagonally opposite to the lamp beads of the LED lamp board 3. A second air outlet pipe 94 is fixed between the annular air pipe 91 and the sealed piston box 61. A second air inlet check valve 95 and a second air outlet check valve 96 are respectively embedded and installed on one side of the sealed piston box 61 close to the drive motor 66. The second air outlet pipe 94 and one end of the second air outlet check valve 96 are connected, and one end of the second air inlet check valve 95 is connected to a second air inlet pipe 97.

[0034] Specifically, when the piston plate 65 moves from left to right, cold air will be sucked into the left side space of the piston plate 65 by the second air inlet pipe 97, and when the piston plate 65 moves from right to left, the sucked cold air will enter the annular air supply pipe 91 and the diversion pipe 92 respectively through the second air outlet pipe 94, and finally be discharged from multiple nozzles 93, so that the nozzles 93 at multiple positions will blow air outward in turn, and the outside of the LED lamp board 3 will be blown and cleaned, which can remove dust and dirt on the surface of the lamp board to a certain extent, maintain the cleanliness of the LED lamp board 3, thereby extending its service life and avoiding the adhesion of debris.

[0035] Example 4: Please refer to Figure 7 and Fig.11 This embodiment further illustrates other embodiments, and the difference lies in that a synchronous deceleration unit 12 is added, which can further optimize the heat dissipation method of the LED corn lamp.

[0036] Specifically, the synchronous reduction unit 12 includes a worm wheel 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 wheel 121 and the worm 122 are meshed and connected. The worm 122 is fixedly connected to one end of the reciprocating screw 63 away from the driving motor 66. The worm wheel 121 and the first reduction gear 124 are both fixedly sleeved with 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 with 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 increasing sizes.

[0037] Specifically, when the driving motor 66 drives the reciprocating screw 63 to rotate, it will also drive the worm 122 to rotate, and the worm 122 will drive the worm wheel 121 to rotate, and then drive the three sets of reduction gears for transmission through the transmission rod 123. The three sets of reduction gears will gradually reduce the speed output by the reciprocating screw 63, that is, after the reciprocating screw 63 rotates multiple times, the third reduction gear 126 just rotates 2-3 times, and the driving rod 542 also rotates 2-3 times, and finally drives the mounting stud 42 to screw out a lead distance of 2-3 turns, and one side of the lamp cover 2 will move a short 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, 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 be automatically discharged from the gap, that is, the exchange rate of the airflow below the lamp body 1 can be further accelerated, and the heat dissipation efficiency of the entire corn lamp can be further accelerated.

[0038] It should be noted that a dustproof net (not numbered 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, reducing dust from entering the interior of the lamp body 1 again.
