DETAILED DESCRIPTION OF THE EMBODIMENTS

(16) Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

(17) As shown in FIGS. 1-6, an embodiment of the present invention provides a lamp module group, including: the LED lamp board 1, the power supply driving module 2, the concentric male terminal 3, and the first housing 4. The first housing 4 has a cylindrical structure, the convex ring 5 having a ring structure is provided on an inner wall of the first housing 4 close to an upper open end. An upper surface of the convex ring 5 is installed on the LED lamp board 1 by the screw 8. The power supply driving module 2 is provided below the LED lamp board 1 with an interval. An output end of the power supply driving module 2 is connected to a power supply input end of the LED lamp board 1 through the wire 9. An input end of the power supply driving module 2 is connected to an output end of the concentric male terminal 3 through the wire 9. A lower surface of the first housing 4 is provided with the first protruding column 6 with a ring structure. The first protruding column 6 and the first housing 4 are provided to be in communication with each other. One end of the concentric male terminal 3 close to the power supply driving module 2 is fixed in the first housing 4, and the other end of the concentric male terminal 3 extends out of an inner cavity of the first protruding column 6 and is connected to the concentric female terminal 7. An end of the concentric female terminal 7 away from the concentric male terminal 3 is installed in the second housing 29. The waterproof rubber ring 30 is provided between the first housing 4 and the second housing 29.

(18) The lamp module group provided in the present invention can achieve the purposes of heat conduction and heat dissipation, waterproofing, and rotational coaxial connection power extraction by the provided first housing 4, second housing 29, concentric male terminal 3 and concentric female terminal 7, and can realize the waterproofing between the first housing 4 and the second housing 29 by the first housing 4 causing a second housing 29 where the concentric male terminal 3 and the concentric female terminal 7 are located to squeeze the waterproofing rubber ring 30.

(19) The first housing 4 and the second housing 19 are connected into one body by a thread, which may conduct the heat of the power supply driving module 2 and the LED lamp board 1. Specifically, the heat of the power supply driving module 2 and the LED lamp board 1 is conducted to the second housing 29 where the concentric female terminal 7 is located through the connection between the first housing 4 and the second housing 29, thereby achieving the purpose of dissipating the heat of the power supply driving module 2 and the LED lamp board 1;

(20) By the provided concentric female terminal 7 and concentric male terminal 3, the coaxial rotational connection and power extraction during thread installation of the first housing 4 and the second housing 29 are achieved.

(21) The lamp module group has a structure that can realize heat conduction, waterproofing, and rotational coaxial connection power extraction. Meanwhile, the external thread provided on the first housing 4, the external thread provided on the first protruding column 6, and the concentric male terminal 3 in conjunction with the concentric female terminal 7 can be combined with other accessories or extension accessories to form a variety of lamps, thereby improving the use range of the lamp module group.

(22) During specific work, the concentric male terminal 3 and the concentric female terminal 7 are each provided with a waterproof structure. The power supply driving module 2 is filled with glue between the concentric male terminal 3 and the LED lamp board 1, thereby forming the first sealing layer 11 in the first housing 4 so that the power supply driving module 2 is completely sealed in the first sealing layer 11. A side of the LED lamp board 1 away from the power supply driving module 2 is also fixed in the first housing by the screw 8. An upper surface of the screw 8 is provided with the second sealing layer 12. The second sealing layer 12 is configured to seal a gap between the screw 8 and the LED lamp board 1. Thus, the LED lamp board 1 and the concentric male terminal 3 are enabled to achieve the purpose of complete waterproofing in the first housing 4. The power supply driving module 2, the power terminal of the LED lamp board 1, and the concentric male terminal 3 are each enabled to achieve the purpose of waterproofing and modularization. When it is required to use, the concentric male terminal 3 and the concentric female terminal 7 are plugged into each other to achieve conduction. An end of the concentric female terminal 7 away from the concentric male terminal 3 is configured to extract power, so that the electrical conduction of the concentric male terminal 3 can be achieved. The power supply driving module 2 is further started. After the power supply driving module 2 is started, the LED lamp board 1 is lit, thereby achieving the work of the lamp module group.

(23) When the lamp module fails to work, the lamp module group installed in the lamp cover can be directly detached and replaced, thereby reducing the waste caused by the direct replacement of the entire lamp cover. Meanwhile, the lamp module group achieves the purpose of sealing and waterproofing by the first sealing layer 11, the second sealing layer 12, and the concentric male terminal 3 and concentric female terminal 7 with sealing and waterproofing capability, which greatly improves the purpose of easy replacement of the lamp module group after failure. Meanwhile, after the LED lamp fails, the lamp module group can be directly replaced rather than the lamp housing and the lamp module group together.

(24) The lamp module group is formed by the concentric male terminal 3, the LED lamp board 1, the power supply driving module 2 and the first housing 4 together, and achieves the purpose of electrically connecting to the power supply by combining the concentric female terminal 7. The lamp module group may also be formed by the concentric male terminal 3, the LED lamp board 1, the power supply driving module 2, and the concentric female terminal 7 together. The combination manners of the above two lamp module groups each extract power through one end of the concentric female terminal. Then, the concentric male terminal is connected to the concentric female terminal and conducts the electricity to the power supply driving module 2, thereby achieving the purpose of the power supply communicating with the power supply driving module 2 and starting the work of the LED lamp board 1.

(25) The first housing 4 and the second housing 29 configured for installing the concentric female terminal 7 are each made of a metal material. The first housing 4 tightly contacts each of the concentric male terminal 3, the power supply driving module 2 and the LED lamp board 1 through the first sealing layer 11, and thus the thermal energy generated by the power supply driving module 2 and the LED lamp board 1 can be conducted through the first housing 4 and the second housing 29. Therefore, the heat dissipation efficiency of the power supply driving module 2 and the LED lamp board 1 is improved, the failure of the power supply driving module 2 and the LED lamp board 1 due to overheating is reduced, and the service life of the power supply driving module 2 and the LED lamp board 1 is improved. Meanwhile, the aging of the concentric male terminal 3, the concentric female terminal 7 and the wire 9 is reduced, effectively extending the service life of the lamp module group.

(26) As shown in FIGS. 1-2, sides of the LED lamp board 1 and the screw 8 close to the upper open end of the first housing 4 are provided with the second sealing layer 2. The reflecting cup 13 is sleeved above the second sealing layer 2. The lens 14 is sleeved at a center of the reflecting cup 1. The lens 14 is configured to be fastened on a light emitting part of the LDE lamp board.

(27) The second sealing layer 12 can make it difficult for water or mist to enter the LED lamp board 1 from a hole of the screw 8 during the use of the LED lamp board 1. The reflecting cup 13 can reflect light on the LED lamp board 1 to makes the light brighter, and meanwhile, can cover an upper surface of the LED lamp board 1 to further achieve the purpose of waterproofing. The lens 14 can not only condense the LED light, but also can achieve the purpose of further waterproofing of the LED lamp board 1.

(28) As shown in FIGS. 1-2, the first sealing layer 11 is provided between the LED lamp board 1 and the power supply driving module 2. The first sealing layer 11 is configured for sealing and fixing the LED lamp board 1, the power supply driving module 2, and the wires 9 together in the first housing 4.

(29) The first sealing layer 11 can enable the LED lamp board 1 and the power supply driving module 2 to achieve the purpose of waterproof sealing in the first housing 4, so that the LED lamp board 1 and the power supply driving module 2 can form one integral member via the first sealing layer 11.

(30) As shown in FIGS. 1-2, the insulating sheet 10 having a ring structure is provided on an inner wall of an end of the first housing 4 close to the first protruding column 6. A lower surface of the insulating sheet 10 and an inner bottom of the first housing 4 are attached to each other. An upper surface of the insulating sheet 10 is fixed inside the first housing 4 via the first sealing layer 11.

(31) The insulating sheet 10 can achieve the purpose of insulation and separation between the first sealing layer 11 and the first housing 4, and meanwhile, can also enable the first sealing layer 11 to achieve the purpose of performing isolation and padding between the first housing 4 and the concentric male terminal 3 during the filling of the first sealing layer 11 in the first housing 4.

(32) As shown in FIG. 3, the concentric female terminal 7 includes the first insulating casing 15, the conductive metal ring 16, the conductive spring sheet 17, and the first plastic insulating boss 18.

The conductive spring sheet 17 protruding toward an axial centerline direction of the conductive metal ring 16 is provided on an annular inner wall of the conductive metal ring 16. An outer wall of the conductive metal ring 16 is connected to the wire 9. A lower portion of the conductive metal core 20 extends downward from a center of the first plastic insulating boss 18 and is connected to the wire 9. The conductive metal ring 16 is configured to insert the concentric male terminal 3. A first limiting boss 24 protruding outward is provided on a circumferential outer wall of an end of the first insulating casing 15 close to the circular notch. The first limiting boss 24 and the circular notch end face the concentric male terminal 3, and are configured to cooperate with the concentric male terminal 3.

(33) The concentric female terminal 7 is configured for plugging into the concentric male terminal 3 and realizing electrical connection, so that the concentric female terminal 7 extracts power from a power supply at an end away from the concentric male terminal 3, conducts the electricity to the power supply driving module 2, and then lights the LED lamp board 1 via the power supply driving module 2.

(34) The conductive spring sheet 17 and the conductive metal core 20 of the concentric female terminal 7 are configured for inserting the concentric male terminal 3. The conductive spring sheet 17 can press the concentric male terminal 3 into a power extraction end of the concentric female terminal 7, so that the concentric male terminal 3 can be fully attached to the conductive metal core 20. Thus, the concentric male terminal 3 and the concentric female terminal 7 can be in good contact, and the situation of power-off or virtual connection of the power supply in power extraction due to poor contact is reduced.

(35) As shown in FIG. 4, the concentric male terminal 3 includes the second insulating casing 21, the second plastic insulating boss 19, the outer conductive metal pipe 22 and the first inner conductive metal pipe 23.

A diameter of the third insulating column is smaller than a diameter of the second plastic insulating boss 19. The outer conductive metal pipe 22 is provided between the third insulating post and the second insulating casing 21.

One end of the second inner conductive metal pipe 25 close to a bottom of the notch is provided with the wire 9. The wire 9 at one end away from the second inner conductive metal pipe 25 penetrates and extends out of the second insulating casing 21. Another wire 9 is further connected to an outer wall of the outer conductive metal pipe 22. The wire 9 at one end away from the outer conductive metal pipe 22 penetrates and extends out of the second insulating casing 21. The second inner conductive metal pipe 25 is further embedded with the first inner conductive metal pipe 23. The lower end of the first inner conductive metal pipe 23 is provided with an opening having a circular structure. The opening is configured for installing the concentric female terminal 7. A circumferential outer wall of an end of the second insulating casing 21 close to the opening of a circular groove is provided with the second limiting boss 27. The second limiting boss 27 and the second insulating casing 21 are each configured to be inserted into and fixed in the first protruding post 6. An end of the first protruding post 6 away from the first housing 4 is further provided with the first limiting groove 28. A diameter of a notch of the first limiting groove 28 is larger than a diameter of a central through hole of the first protruding post 6. The first limiting groove 28 is configured for embedding the second limiting boss 27.

(36) Further, both the concentric male terminal 3 and the concentric female terminal 7 can achieve 360-degree rotation after being plugged, and can further ensure that the power-on state is still maintained during the rotation. Moreover, the twisted disconnection of the wire 9 is avoided during the rotation.

(37) During use, one end of the first inner conductive metal pipe 23 of the concentric male terminal 3 is inserted into the conductive metal core 20 of the concentric female terminal 7. The other end of the concentric male terminal 3 is a wire 9 end. The wire 9 at the wire 9 end is electrically connected to the power supply driving module 2. Meanwhile, the second insulating casing 21 provided at the wire 9 end of the concentric male terminal 3 is inserted into an inner cavity of the first housing 4 and is collectively sealed and fixed in the first housing via the first sealing layer 11. One end of the second limiting boss 27 of the concentric male terminal 3 close to the second insulating casing 21 is closely attached to a groove bottom of a first limiting groove. The second limiting boss 27 is completely placed in the first limiting groove. Thus, the second insulating casing 21 and the second limiting boss 27 of the concentric male terminal 3 are completely located in the first protruding column 6 and the inner cavity of the first housing.

(38) As shown in FIGS. 3-5, the conductive metal ring 16 and the conductive spring sheet 17 of the concentric female terminal 7 are provided to be communicated with each other through the wire 9, and form a third communication line in the concentric female terminal 7. The conductive metal core 20 forms a fourth communication line in the notch of the first insulating casing 15 via the first plastic insulation boss 18. The first inner conductive metal pipe 23 and the second inner conductive metal pipe 25 of the concentric male terminal 3 are each made of a metal material. The first conductive metal pipe is a circular notch provided on the second conductive metal pipe, thereby forming a first communication line. The outer conductive metal pipe 22 is separated by the third plastic insulating column 26 from the circumferential outer wall of the second conductive metal pipe. The outer conductive metal pipe 22 penetrates the second insulator housing through the wire 9 and forms a second communication line. An end of the concentric male terminal 3 away from the concentric female terminal 7 is configured to connect the power supply driving module 2. An end of the concentric female terminal 7 away from the concentric male terminal 3 is configured to connect a power supply. The first communication line and the third communication line are provided to be turned on; the second communication line and the fourth communication line are provided to be turned on. When the concentric male terminal 3 and the concentric female terminal 7 are communicated with each other, the first communication line and the second communication line are not turned on. The third communication line and the fourth communication line are not turned on.

(39) As shown in FIG. 5, a circumferential outer wall of the first protruding post 6 is provided with an external thread. The external thread is configured for installing the second housing 29. The second housing 29 has a tubular structure. The installing table 31 with a tapered structure is provided below the tubular structure. An end of the installing table 31 away from the second housing 29 is provided with a through hole. The through hole is configured for installing the first limiting boss 24 of the concentric female terminal 7.

An upper surface of the first limiting boss is provided with the waterproofing rubber ring 30.

(40) The second housing 29 is configured for fixing the concentric female terminal 7 and enables the concentric female terminal 7 to be protected by the second housing 29, which is also beneficial for the concentric female terminal 7 and the concentric male terminal 3 to be better installed as one body.

(41) During use, an internal thread provided on an inner wall of one end of the second housing 29 away from the installing table 31 is installed to the external thread of the first protruding column 6 provided on the first housing 4. The waterproof rubber ring 30 with a ring structure is further provided between the second housing 29 and the first protruding column 6. The waterproof rubber ring 30 enables a gap between the first housing 4 and the second housing 29 to achieve the purpose of sealing and waterproofing. Meanwhile, the waterproof rubber ring 30 can achieve the purpose of pressing the waterproof rubber ring 30 between the first housing 4 and the second housing 29 via the first protruding column 6, which not only enhances the contact between the concentric male terminal 3 and the concentric female terminal 7, but also achieves the purpose of sealing and waterproofing.

(42) As shown in FIG. 6, a circumferential outer wall of an end of the first housing 4 away from the first protruding column 6 is provided with an external thread. The external thread is configured for installing the mask 34. A center of the mask 34 is provided with a through installing hole. An inner bottom of one end of the installing hole away from the first housing 4 is embedded with the stepped glass 33. A side of the stepped glass 33 away from an inner ground of the installing hole is provided with the silicone gasket 32 with a ring structure. The silicone gasket 32 is sleeved on a circumferential outer wall of an end of the external thread of the first housing 4. The mask 34 is any one selected from the group consisting of a flat lid, a curved lid, a round beveled cover, a vertical lamp cover, a long tube cover, and a square beveled cover.

(43) During use, the mask 34 is made of a metal material. The mask 34 is connected by using the outer thread of the circumferential outer wall of the end of the first housing 4 away from the concentric male terminal 3, thereby allowing the mask 34 to condense light of the LED lamp board 1 and protecting the LED lamp board 1, the reflecting cup 13, and the lens 14. The silicone gasket 32 allows the mask 34 and the first housing 4 to achieve the purpose of sealing and waterproofing during installation. The stepped glass 33 is a columnar boss glass with a section of a T-shaped structure as shown in FIG. 6. The stepped glass 33 can reduce the situation that water or water mist enters the first housing 4 from outside the mask 34. Thus, the waterproof performance is improved. The mask 34 can conduct thermal energy of the first housing 4 and further achieve the purpose of heat conducting of the power supply driving module 2 and the LDE lamp board.

(44) As shown in FIGS. 7-13, an end of the second housing 29 away from the first housing 4 is fixed on the lamp holder 35. The lamp holder 35 is fixed on the base 36 by the fixing rod 37. An inner wall of the lamp holder 35 is spirally embedded with the cooling pipeline 38. Both ends of the cooling pipe 38 extend from an end of the lamp holder 35 close to the fixing rod 37 onto the base 36. The water storage cavity 66 is provided in the base 36. An upper surface of the water storage cavity 66 is provided with the water inlet 68 and the water outlet 67. The water inlet 68 is connected to the water inlet pipe 70. The water outlet 67 is connected to the water outlet pipe 69. The water inlet pipe 70 and the water outlet pipe 69 are connected to two open ends of the cooling pipeline 38, respectively. One end of the lamp holder 35 close to the second housing 29 is provided with the ventilation plate 39. One end of the ventilation plate 39 away from the second housing 29 is provided with a fan and a water pressure adjusting device. The fan is provided to be close to the ventilation plate 39. One end of the water pressure adjusting device is connected to a driving device, and the other end is connected to an end of the cooling pipeline 38 close to the water outlet pipe 69. A circumferential outer wall of the water storage cavity 66 is further provided on the water injecting port 71.

(45) The first housing 4 can achieve the purpose of installing with various specifications of lamp holders 35. The lamp holder 35 may have a chandelier structure that is hung on a roof or a cantilever by a lifting ring, or a ceiling structure that is directly installed on the roof or the cantilever by the screw 8. Or, the lamp holder 35 is a floodlight or underwater lamp fixed by the fixing rod 37 and the base 36. When the lamp holder 35 is used as a floodlight or underwater lamp, the base 36 fixes the lamp holder 35 by the fixing rod 37, thereby achieving the purpose of installing and fixing the lamp module group. The cooling pipeline 38 provided in the lamp holder 35 is spirally provided on the inner wall of the lamp holder 35, and therefore the reduction of the temperature in the lamp holder 35 can be achieved. Since the lamp module is installed between the lamp holder 35 and the mask 34, the purpose of heat conduction and heat dissipation for the lamp module group can be achieved by both the lamp holder 35 and the mask 34. Thus, the cooling pipeline 38 can perform water-cooling circulation through the water storage cavity 66 provided in the base 36. In addition, a fan is further provided in the lamp holder 35. The fan blows the ventilation plate 39. The ventilation plate 39 has a circular plate structure. A surface of the circular plate structure is provided with a plurality of spaced ventilation holes. The ventilation holes are beneficial for the wind of the fan to be blown toward an end of the concentric female terminal 7 away from the concentric male terminal 3, and thus the purpose of air cooling the concentric female terminal 7 and the lamp holder 35 is achieved.

(46) As shown in FIGS. 8-13, the fan includes the blade 47, the third rotating shaft 48, and the motor 49.

(48) The water injecting port 71 is configured to add or discharge water into or from the water storage cavity 66. An open end of the water injecting port 71 is provided with a sealing plug. When the water needs to be added or discharged, the purpose of adding or discharging the water into or from the water storage cavity 66 can be achieved by removing the sealing plug.

(49) The inside of the lamp holder 35 can be air-cooled by using the fan. The water in the water storage cavity 66 can be adsorbed into the cooling pipeline 38 by the water pressure adjusting device, improving the water flow speed of the cooling pipeline 38, achieving the purpose of accelerating the cooling of the cooling pipeline 38, and further making the water in the cooling pipeline 38 cool the heat of the lamp holder 35, the first housing 4 and the second housing 29. Thus, the service life of the lamp module group is improved. During a specific work, the fan is first started to work. After the fan is started to work, the water pressure adjusting device is linked to work. After the water pressure adjusting device works, the fan and the water pressure adjusting device can jointly achieve air cooling and water cooling, thereby achieving the purpose of cooling the lamp module group.

(50) Its working principle is as follows: the motor 49 is connected to a power supply through the wire 9. When the power supply is started, the motor 49 and the lamp module are separately started. After the motor 49 is started, the fourth rotating shaft 50 rotates. After the fourth rotating shaft 50 rotates, the first gear 40 is driven to rotate. The first gear 40 rotates and then engages with the second gear 41 to rotate. The second gear 41 rotates and then drives the third rotating shaft 48 and the first rotating shaft 42 to rotate. The third rotating shaft 48 rotates and then drives the blade 47 to rotate. The blade 47 rotates to achieve blowing. The wind of the blade 47 is blown toward the second housing 29 via the ventilation plate 39, so that the purpose of air cooling the second housing 29 is achieved.

(51) After the first rotating shaft 42 rotates, the first connecting rod 45 is driven to rotate. The first connecting rod 45 rotates, allowing the fourth protruding column 43 on the first connecting rod 45 to make a circular motion around the axial centerline of the first rotating shaft 42, thereby driving the third connecting rod 63 fixedly provided on the third shaft sleeve 46 to rotate, and then the third connecting rod 63 makes a circular motion along with it.

(52) An end of the third connecting rod 63 away from the first connecting rod 45 is rotatably provided on the third protruding column 64. The third protruding column 64, the first connecting plate 54, and the second connecting plate 55 each are fixedly connected. The other end of the fourth connecting plate 57 is fixed to the circumferential outer wall of the fifth rotating shaft 59 through the first shaft sleeve 58. Both ends of the fifth rotating shaft 59 are rotatably provided on the inner wall of the lamp holder 35. Thus, the third connecting rod 63 allows the first connecting plate 54 and the second connecting plate 55 to swing. The sliding rod 53 connected to the first connecting plate 54 moves back and forth on the slideway 52, and drives the fifth rotating shaft 59 to rotate back and forth. The fifth rotating shaft 59 rotates back and forth, and then drives the second shaft sleeve 65 and the fifth connecting plate 60 to swing back and forth. The fifth connecting plate 60 swings, and then drives the second connecting rod 61 in FIG. 8 to move left and right. The second connecting rod 61 in FIG. 9 is shown to move up and down.

(53) An end of the second connecting rod 61 away from the fifth connecting plate 60 is fixedly connected to the plunger rod 73. The plunger rod 73 also moves back and forth, thereby allowing the movable plug 74 to move back and forth in the piston pipe 72. When the movable plug 74 moves back and forth in the piston pipe 72, the air pressure in the piston pipe 72 will change. In FIG. 12, when the plunger rod 73 moves to the right, the second check valve 76 is opened and the first check valve 75 is closed. The water in the water storage cavity 66 is introduced into the cooling pipeline 38 between the first check valve 75 and the second check valve 76 via the water outlet 67 and the water outlet pipe 69, and fully fills the cooling pipeline 38 located between the first check valve 75 and the second check valve 76. When the plunger rod 73 moves to the left, the second check valve 76 is closed and the first check valve 75 is opened. The water in the cooling pipeline 38 located between the first check valve 75 and the second check valve 76 is pressurized and flows from the first check valve 75 to the other end of the cooling pipeline 38. The repeat allows the water in the water storage cavity 66 to intermittently flow into the cooling pipeline 38 via one end of the cooling pipeline 38, and then flow back to the water storage cavity 66 via the other end of the cooling pipeline 38, thereby achieving the purpose of circulating the water in the cooling pipeline 38. The cooling efficiency can be accelerated, so that the lamp module can achieve the purpose of accelerated cooling.
