Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and in particular to an LED combination lighting fixture. Background Technology

[0002] LED lights, as the mainstream lighting equipment currently in widespread use, have many advantages such as energy efficiency, high efficiency, and long lifespan, but they still have obvious structural design limitations in actual use.

[0003] Currently, most LED lighting products on the market are independent units, and their modular assembly was not considered in the initial design. Different LED lights lack physical interfaces that can be connected and combined with each other. As a result, users cannot flexibly combine multiple lighting units to customize the required lighting form, coverage area or overall size, which limits their use.

[0004] Furthermore, even though a few LED lighting products on the market support modular assembly, their system design is still not perfect, leading to new user pain points. On the one hand, these modular lighting products typically require each independent unit to be equipped with a separate power input point, resulting in repetitive and tedious wiring operations when assembling multiple units. This not only increases installation complexity but also leads to problems such as chaotic circuit layout and increased safety hazards.

[0005] In view of the above problems, it is necessary to study an LED combination lighting fixture to overcome the shortcomings of the existing technology. Summary of the Invention

[0006] The purpose of this invention is to provide an LED combination lighting fixture to overcome the shortcomings of the prior art.

[0007] To achieve the above objectives, the solution of the present invention is: An LED combination lighting fixture includes at least two detachably connectable LED lighting fixtures. Each LED lighting fixture includes a fixture body and an LED lighting module disposed within the fixture body. The fixture body has at least one connecting device, which has at least two connecting units. Each connecting unit has a connecting plate, a connecting port, a positive contact, and a negative contact. The connecting plate has positive and negative contacts that are electrically connected to the LED lighting module. The positive and negative contacts mate with the connecting port and can extend into the connecting port, and are also electrically connected to the LED lighting module. When the two LED lighting fixtures are combined, the maximum number of LEDs in one LED lighting fixture can be detachably connected to the LED lighting module. One of the connection units of a connection device is connected to the connection unit of at least one connection device of another LED lamp; and when the connection unit of a connection device of one LED lamp is connected to the connection unit of a connection device of another LED lamp, the connection plate of the connection unit of the connection device of one LED lamp is plugged into the connection port of the connection unit of the connection device of another LED lamp, and the positive and negative contacts of the connection plate of the connection unit of the connection device of one LED lamp are in contact with the positive and negative contacts of the connection unit of the connection device of another LED lamp respectively, and are conducting.

[0008] The connecting plate of the connecting unit protrudes from the side of the lamp body, and the connecting plate of the connecting unit is provided with an insertion hole arranged along the axial direction of the lamp body; the connection port of the connecting unit is located on one side of the lamp body; the connecting unit also has a pin that fits into the connection port and can move elastically; when the connecting unit of one connecting device of one LED lamp is connected to the connecting unit of another connecting device of one LED lamp, the pin of the connecting unit of one connecting device of one LED lamp is inserted into the insertion hole of the connecting unit of the connecting device of another LED lamp.

[0009] The lamp body has at least two connecting devices, each connecting device is arranged separately, each connecting unit of each connecting device is aligned one by one, and each row of aligned connecting units is correspondingly matched with a connecting component. The connecting component includes a movable connecting rod that is matched in the lamp body, and a return spring that drives the connecting rod to return to its original position; the connecting rod of the connecting component is connected to the pin of each connecting unit that is matched with it.

[0010] The pin of the connecting unit has a beveled guide surface at its end.

[0011] The connecting device also includes a connecting circuit board. The connecting circuit board of the connecting device has a positive contact and a negative contact corresponding to each connecting unit of the connecting device. The connecting plate of each connecting unit is connected to the connecting circuit board of the connecting device, and the positive and negative contacts of the connecting plate are electrically connected to the positive and negative contacts, respectively. The connecting unit has a positive conductive component and a negative conductive component that are elastically movable and fit into the connecting port. The positive conductive component has a positive guide post and the positive contact, and the negative conductive component has a negative guide post and the negative contact. The positive guide post and the negative guide post of each connecting unit are in movable contact with the corresponding positive and negative contacts of the connecting unit, respectively.

[0012] The lamp body has at least two connecting devices, which are arranged separately. Each connecting unit of each connecting device is aligned one by one, and each row of aligned connecting units is correspondingly matched with a connecting component. The connecting component includes a movable connecting rod that fits into the lamp body and a reset spring that drives the connecting rod to reset. The connecting rod of the connecting component is connected to the positive and negative conductive parts of each connecting unit that cooperates with the connecting component. The connecting rod of the connecting component is provided with positive and negative connecting lines. The positive and negative connecting lines of the connecting rod of the connecting component are electrically connected to the positive and negative conductive parts of each connecting unit that cooperates with the connecting component.

[0013] The connecting circuit board of a connecting device adjacent to the LED lighting module in the main body of the lamp is electrically connected to the LED lighting module.

[0014] The connecting rod of the connecting assembly is connected to an operating head, which is made of insulating material and has an operating part that extends out of the lamp body.

[0015] The connecting rod of the connecting assembly is provided with sliding pins that slide in cooperation with each connecting device of the lamp body respectively; the return spring of each connecting assembly is sleeved on at least one sliding pin of the connecting rod of the connecting assembly, one end of the return spring of each connecting assembly abuts against the connecting rod of the connecting assembly, and the other end of the return spring of each connecting assembly abuts against a connecting device of the lamp body.

[0016] The connecting rod of the connecting component is provided with a spring post for movable engagement with the connecting plate. The spring post of each connecting component extends into a connection port of a connecting device and moves against the connecting device. The connecting device against which the spring post is against is provided with a through hole for the spring post to move through. When two LED lamps are spliced, the connecting plate of the connecting unit of the connecting device of one LED lamp is inserted into the connection port of the connecting device of another LED lamp and abuts against the spring post of the corresponding connecting component of the connecting device. This causes the spring post of the connecting component to deform and disengage from the connecting device, allowing the spring post of the connecting component to insert into the through hole of the corresponding connecting device.

[0017] The end of the spring is provided with a protruding head.

[0018] The main body of the lamp also has at least two lamp tubes, and a connecting device is sandwiched between two adjacent lamp tubes. The connecting device is hollow and connected to the lamp tubes.

[0019] The connecting device also has a first insulating plate and a second insulating plate, and the connecting plates of each connecting unit of the connecting device are sandwiched between the first insulating plate and the second insulating plate, and the connecting ports of each connecting unit of the connecting device are formed between the first insulating plate and the second insulating plate.

[0020] The connecting plate of the connecting unit protrudes from the side of the lamp body; the connecting port of the connecting unit is located on one side of the lamp body; the side of the lamp body has a recess corresponding to the connecting plate, and the side of the lamp body has a protrusion corresponding to the connecting port; when the connecting unit of one LED lamp's connecting device is connected to the connecting unit of another LED lamp's connecting device, the recess corresponding to the connecting plate of one LED lamp's connecting device matches the protrusion corresponding to the connecting port of another LED lamp's connecting device.

[0021] Each LED luminaire in the assembly is a main LED luminaire, and the rest are secondary LED luminaires; the main LED luminaire also has a power cord that connects to the LED lighting module of the main LED luminaire.

[0022] The positive contacts of the connecting plate are exposed on both sides of the connecting plate, and the negative contacts of the connecting plate are exposed on both sides of the connecting plate.

[0023] With the above solution, when two LED lamps are spliced ​​together, the connection unit of at least one connection device of one LED lamp is connected to the connection unit of at least one connection device of the other LED lamp; and when the connection unit of one connection device of one LED lamp is connected to the connection unit of one connection device of another LED lamp, the connection plate of the connection unit of one connection device of one LED lamp is inserted and engaged with the connection port of the connection unit of one connection device of another LED lamp, so that the two LED lamps are spliced ​​together, and the positive and negative contacts of the connection plate of the connection unit of one connection device of one LED lamp are respectively in contact with the positive and negative contacts of the connection unit of one connection device of another LED lamp, so that the connection devices of the two LED lamps can be connected and current can be transmitted.

[0024] As can be seen from the above, the LED combination lamp of the present invention can splice different LED lamps, and the connection device of the spliced ​​LED lamps can achieve conductivity; thus, users can flexibly select the number, brightness and color temperature of the spliced ​​LED lamps according to actual lighting needs, thereby constructing a lighting system that meets the requirements of a specific scenario; moreover, the present invention only needs to supply power to one LED lamp to enable all the spliced ​​LED lamps to work, simplifying wiring requirements.

[0068] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0069] Example 1: like Figures 1 to 32As shown, in Embodiment 1 of the present invention, the LED combination lamp of the present invention includes at least two detachably connected LED lamps A; wherein, the LED lamp A includes a lamp body A1 and an LED lighting module A2 disposed in the lamp body A1; the lamp body A1 has at least one connecting device 1, the connecting device 1 is provided with at least two connecting units 11, the connecting unit 11 has a connecting plate 111, a connecting port 112, a positive contact 1131 and a negative contact 1141, the connecting plate 111 is provided with a positive contact 1111 and a negative contact 1112 electrically connected to the LED lighting module A2, the positive contact 1131 and the negative contact 1141 are fitted at the location of the connecting port 112 and can extend into the connecting port 112, the positive contact 1131 and the negative contact 1141 are also electrically connected to the LED lighting module A2; when the two LED lamps A are spliced, at least one connecting device of one LED lamp A The connection unit 11 of one LED lamp A is connected to the connection unit 11 of at least one connection device 1 of another LED lamp A; and when the connection unit 11 of the connection device 1 of one LED lamp A is connected to the connection unit 11 of the connection device 1 of another LED lamp A, the connection plate 111 of the connection unit 11 of the connection device 1 of one LED lamp A is inserted and engaged with the connection port 112 of the connection unit 11 of the connection device 1 of another LED lamp A so that the two LED lamps are spliced ​​together, and the positive contact 1111 and the negative contact 1112 of the connection plate 111 of the connection unit 11 of the connection device 1 of one LED lamp A are respectively in contact with the positive contact 1131 and the negative contact 1141 of the connection unit 11 of the connection device 1 of another LED lamp A so that the connection devices 1 of the two LED lamps A can be connected and current can be transmitted.

[0070] As described above, the LED combination lamp of the present invention can splice different LED lamps A together, and the connecting device 1 of the spliced ​​LED lamps A can achieve conductivity; thus, users can flexibly select the number, brightness and color temperature of the spliced ​​LED lamps A according to actual lighting needs, thereby constructing a lighting system that meets the requirements of a specific scenario; moreover, the present invention only needs to supply power to one LED lamp A to enable all the spliced ​​LED lamps A to be powered on and work, simplifying wiring requirements.

[0071] In Embodiment 1 of the present invention, the positive contact 1111 of the connecting plate 111 is exposed on both sides of the connecting plate 111, and the negative contact 1112 of the connecting plate 111 is exposed on both sides of the connecting plate 111. With this configuration, the connecting plate 111 can be inserted into the connecting port 112 in both directions, and it can be ensured that the positive contact 1111 and the negative contact 1112 of the connecting plate 111 make contact and conduction with the positive contact 1131 and the negative contact 1141 respectively. This allows for more flexible and convenient connection between LED lamps A, and the light emission direction of each connected LED lamp A can be different, thus flexibly adjusting the illumination range of the LED lamp A of the present invention.

[0072] In Embodiment 1 of the present invention, the connecting plate 111 of the connecting unit 11 protrudes from the side of the lamp body A1, and the connecting port 112 of the connecting unit 11 is located on one side of the lamp body A1 for the connecting plate 111 to be inserted; the connecting plate 111 of the connecting unit 11 is provided with a socket 1113 arranged along the axial direction of the lamp body A1; the connecting unit 11 also has a pin 115 that fits into the connecting port 112 and is elastically movable; when the connecting unit 11 of one connecting device 1 of one LED lamp A is connected to the connecting unit 11 of another LED lamp A, the pin 115 of the connecting unit 11 of one connecting device 1 of one LED lamp A is inserted into the socket 1113 of the connecting unit 11 of the other LED lamp A; in this way, the two connected LED lamps A can be more firmly connected and are not easy to separate. In addition, the side of the lamp body A1 is provided with a recess 5 corresponding to the connecting plate 111, and the side of the lamp body A1 is provided with a protrusion 6 corresponding to the connection port 112. When the connecting unit 11 of the connecting device 1 of one LED lamp A is connected to the connecting unit 11 of the connecting device 1 of another LED lamp A, the recess 5 corresponding to the connecting plate 111 of the connecting unit 11 of the connecting device 1 of one LED lamp A matches the protrusion 6 corresponding to the connection port 112 of the connecting unit 11 of the connecting device 1 of another LED lamp A; in this way, the two connected LED lamps A can be more firmly connected and are not easy to separate.

[0073] In Embodiment 1 of the present invention, the lamp body A1 specifically has at least two connecting devices 1, which are arranged separately. Each connecting unit 11 of each connecting device 1 is aligned one-to-one. This arrangement allows adjacent LED lamps A to be spliced ​​in a staggered manner, improving splicing flexibility. Furthermore, each row of aligned connecting units 11 of the lamp body A1 can be correspondingly fitted with a connecting component A3. The connecting component A3 includes a movable connecting rod A31 fitted within the lamp body A1 and a return spring A32 that drives the connecting rod A31 to return to its original position. The connecting rod A31 of the connecting component A3 is connected to the pins 115 of each cooperating connecting unit 11, enabling unified control of the movement of these pins 115. The spring A32 allows the connecting rod A31 and the pin 115 connected to the connecting rod A31 to move elastically, thereby ensuring that the pin 115 can be stably inserted into the socket 1113. The user can drive the connecting rod A31 to move the pin 115, thereby controlling the pin 115 to enter and exit the corresponding socket 1113 for disassembly and assembly between different LED lamps A. In order to facilitate the smooth insertion of the pin 115 into the socket 1113, the pin 115 of the connecting unit 11 is designed with a beveled guide surface 1151 at its end. The beveled guide surface 1151 can guide the pin 115 into the socket 1113 when the connecting plate 111 is inserted into the connecting port 112. The connecting rod A31 and the pin 115 connected to it can be set as a single unit.

[0074] In Embodiment 1 of the present invention, the connecting device 1 further includes a connecting circuit board 12. The connecting circuit board 12 of the connecting device 1 is provided with a positive contact 121 and a negative contact 122 corresponding to each connecting unit 11 of the connecting device 1. The connecting plate 111 of each connecting unit 11 of the connecting device 1 is connected to the connecting circuit board 12 of the connecting device 1, and the positive contact 1111 and the negative contact 1112 of the connecting plate 111 are electrically connected to the positive contact 121 and the negative contact 122 respectively. The connecting plate 111 and the connecting circuit board 12 can be made of the same PCB board. The connecting unit 11 has a positive conductive element 113 and a negative conductive element 114 that are elastically movable and fit into the connecting port 112. The positive conductive element 113 is provided with a positive guide post 1132 and the positive contact 114. The head 1131 and the negative conductive component 114 are provided with a negative conductive post 1142 and a negative contact 1141. The positive conductive post 1132 and the negative conductive post 1142 of each connection unit 11 are in movable contact with the corresponding positive contact 121 and negative contact 122 of the connection unit 11. With this configuration, the positive conductive component 113 and the negative conductive component 114 can move elastically, ensuring that the positive contact 1131 and the negative contact 1141 can stably contact the positive contact 1111 and the negative contact 1112 of the connection plate 111 respectively during the connection process (and also ensuring that the positive conductive post 1132 and the negative conductive post 1142 can stably contact the positive contact 121 and the negative contact 122 of the connection circuit board 12 respectively during the connection process), ensuring the reliability of current transmission and avoiding the problem of poor contact. In addition, to facilitate the passage of the positive contact 1131 and the negative contact 1141 through the connecting plate 111, the ends of the positive contact 1131 and the negative contact 1141 are both spherical structures. This provides a guiding function to the ends of the positive contact 1131 and the negative contact 1141, allowing the connecting plate 111 to push the positive contact 1131 and the negative contact 1141 to move smoothly.

[0075] In Embodiment 1 of the present invention, the connecting rod A31 of the connecting assembly A3 is connected to the positive conductive element 113 and the negative conductive element 114 of each connecting unit 11 cooperating with the connecting assembly A3. This allows the return spring A32 of the connecting assembly A3 to elastically move the connecting rod A31 and the positive conductive element 113 and the negative conductive element 114 connected to the connecting rod A31. Furthermore, the connecting rod A31 of the connecting assembly A3 is provided with a positive connecting line A312 and a negative connecting line A313. The positive connecting line A312 and the negative connecting line A313 of the connecting rod A31 of the connecting assembly A3 are electrically connected to the positive conductive element 113 and the negative conductive element 114 of each connecting unit 11 cooperating with the connecting assembly A3. This arrangement ensures that when each connecting unit... When the positive guide post 1132 and negative guide post 1142 of the connection unit 11 are in active contact with the positive contact 121 and negative contact 122 of the corresponding connection unit 11, the connection devices 1 can be electrically connected through the positive connection line A312 and negative connection line A313 of the connecting rod A31. The connection circuit board 12 of the connection device 1 of the lamp body A1, which is adjacent to the LED lighting module A2, is electrically connected to the LED lighting module A2 through the pin header. This enables the connection devices 1 of the lamp body A1 to be electrically connected to the LED lighting module A2, thereby realizing the electrical connection between the positive contact 1111, negative contact 1112, positive contact 1131 and negative contact 1141 of the connection unit 11 and the LED lighting module A2.

[0076] In Embodiment 1 of the present invention, the connecting rod A31 of the connecting component A3 is further provided with a sliding post A311 that slides and engages with each connecting device 1 of the lamp body A1 respectively; the return spring A32 of each connecting component A3 is sleeved on at least one sliding post A311 of the connecting rod A31 of the connecting component A3, one end of the return spring A32 of each connecting component A3 abuts against the connecting rod A31 of the connecting component A3, and the other end of the return spring A32 of each connecting component A3 abuts against a connecting device 1 of the lamp body A1. This design not only ensures the smooth sliding of the connecting rod A31, but also enables the connecting rod A31 to automatically return to its original position after operation through the action of the return spring A32, thereby ensuring that the pin 115, positive contact 1131, negative contact 1141, positive guide post 1132 and negative guide post 1142 can all move elastically.

[0077] In Embodiment 1 of the present invention, to facilitate user operation, the connecting rod A31 of the connecting assembly A3 can also be connected to an operating head A4. The operating head A4 is made of insulating material to ensure safety, and the operating head A4 is provided with an operating part A41 extending outside the lamp body A1, through which the user can control the movement of the connecting rod A31.

[0078] In Embodiment 1 of the present invention, the two ends of the lamp body A1 are respectively provided with a first cover plate 3 and a second cover plate 4. At least one of the first cover plate 3 and the second cover plate 4 is a light-transmitting structure. The LED lighting module A2 can emit light from the light-transmitting first cover plate 3 and / or second cover plate 4. The operating part A41 of the operating head A4 can pass through the lamp body A1 from the first cover plate 3.

[0079] In Embodiment 1 of the present invention, the lamp body A1 may have at least two lamp tubes 2, with a connecting device 1 sandwiched between two adjacent lamp tubes 2. The connecting device 1 is designed as a hollow structure to ensure the light emitted by the LED lighting module A2 can pass through. The connecting device 1 can be locked to the lamp tubes 2 with screws, so that each lamp tube 2 of the lamp body A1 and each connecting device 1 are connected together. In addition, the connecting device 1 also has a first insulating plate 13 and a second insulating plate 14. The connecting plates 111 of each connecting unit 11 of the connecting device 1 are sandwiched between the first insulating plate 13 and the second insulating plate 14, and the connecting ports 112 of each connecting unit 11 of the connecting device 1 are formed between the first insulating plate 13 and the second insulating plate 14. The first insulating plate 13 and the second insulating plate 14 are used to achieve necessary electrical isolation to ensure safe use.

[0080] In Embodiment 1 of the present invention, at least one of the spliced ​​LED lamps A is a main LED lamp A01, and the rest are auxiliary LED lamps A02. The main LED lamp A01 undertakes additional electrical access functions. The main LED lamp A01 also has a power line B connected to the LED lighting module A2 of the main LED lamp A01, through which external power supply is introduced to the entire LED combination lamp.

[0081] Example 2: Cooperate Figures 33 to 42As shown, the difference between Embodiment 2 and Embodiment 1 of the present invention is that in Embodiment 2, the connecting rod A31 of the connecting component A3 is further provided with a spring post A314 for movably cooperating with the connecting plate 111. The spring post A314 of each connecting component A3 extends into a connecting port 112 of a connecting device 1 and the spring post A314 movably abuts against the connecting device 1 (such as the second insulating plate 14). The connecting device 1 to which the spring post A314 abuts is provided with a corresponding through hole 141 for the spring post A314 to move through. When a certain column of connecting units 11 of the LED lamp A is not operated... During connection, the spring pin A314 of the connecting rod A31 of the corresponding connecting component A3 abuts against the corresponding connecting device 1, causing the pins 115, positive contacts 1131, and negative contacts 1141 of each connecting unit 11 that cooperates with the connecting rod A31 of the connecting component A3 to disengage from the corresponding connecting ports 112. This reduces the resistance when the connecting plate 111 is inserted into the connecting port 112 (i.e., it removes the obstruction of the pins 115, positive contacts 1131, and negative contacts 1141 to the connecting plate 111), thus achieving a labor-saving effect; and when two LED lamps A are spliced ​​together A connecting plate 111 of a connecting unit 11 of a connecting device 1 of an LED lamp A is inserted into the connecting port 112 of a connecting device 1 of another LED lamp A and abuts against the spring post A314 of the corresponding connecting component A3 of the connecting device 1. This causes the spring post A314 of the connecting component A3 to deform and disengage from the connecting device 1, allowing the spring post A314 of the connecting component A3 to insert into the through hole 141 of the corresponding connecting device 1. At this time, the connecting rod A31 of the connecting component A3 is reset under the action of the return spring, so that each component cooperating with the connecting rod A31 of the connecting component A3... The pins 115 of each connecting unit 11 extend into the corresponding connecting port 112 and are inserted into the corresponding socket 1113 of the connecting plate 111. At the same time, the positive contacts 1131 and negative contacts 1141 of each connecting unit 11 that cooperates with the connecting rod A31 of the connecting assembly A3 extend into the corresponding connecting port 112 and contact the positive contacts 1111 and negative contacts 1112 of the corresponding connecting plate 111. The positive guide posts 1132 and negative guide posts 1142 of each connecting unit 11 that cooperates with the connecting rod A31 of the connecting assembly A3 contact the corresponding positive contacts 121 and negative contacts 122.

[0082] In the second embodiment of the present invention, the end of the spring A314 may be provided with a protruding head A3141, and the connecting plate 111 can make the spring A314 more easily deformable by abutting against the head A314.
