[0002] At present, two-wire lamp systems are widely used in the field of lamp control due to their simple circuit design, less wiring, low cost, and convenient installation and maintenance. How to improve the construction and maintenance efficiency of two-wire lamp systems is a problem that relevant technical personnel attach great importance to. In the construction and maintenance of two-wire lamp systems, whether it is the installation or replacement of lamps, the connection of the main line and the branch line is an essential link. Traditionally, the operation of connecting the main line and the branch line first requires stripping the insulation layer of the main line, then connecting the main line and the branch line, and finally using materials such as tape for sealing and other processes. This traditional connection method not only has high process requirements and a cumbersome installation process, making it difficult to meet the needs of large-scale operations, but also the sealing materials such as tape are prone to aging, damage, etc., affecting the sealing performance of the connection end, and thus easily causing oxidation or short circuit of the internal metal wiring, as well as leakage, affecting the safe operation of the two-wire lamp system.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the protection scope of the present invention.

[0028] Embodiment 1:

[0029] Referring to Figure 1 、 Figure 2 and Figure 3 shown, a two-wire lamp control system with a piercing buckle 0 includes a central controller 8, a misalignment signal conversion module 9, a voltage stabilizing module 10, a two-wire transmission module 11 and at least one lamp module 12.

[0030] Specifically, the central controller 8, the dislocation signal conversion module 9, and the voltage stabilization module 10 are electrically connected in sequence. The central controller 8 is used to output a driving power supply, a red-channel original control signal, a green-channel original control signal, and a blue-channel original control signal. The dislocation signal conversion module 9 is used to periodically collect the signal states of the red, green, and blue original control signals, and output a red-channel conversion control signal, a green-channel conversion control signal, and a blue-channel conversion control signal in sequence within a single output cycle according to the signal states of the red, green, and blue original control signals. The voltage stabilization module 10 is used to obtain red-channel control signals, green-channel control signals, and blue-channel control signals with different levels after voltage stabilization operations on the red, green, and blue conversion control signals, and form a dislocation control signal with different levels of red-channel control signals, green-channel control signals, and blue-channel control signals and transmit it through the two-wire transmission module 11. The lamp module 12 includes an analysis unit 121 and an LED lamp group 122 electrically connected to the analysis unit 121; the LED lamp group 122 includes red, green, and blue lamps; the analysis unit 121 is used to receive and distinguish the dislocation control signal to respectively obtain red-channel conversion control signals, green-channel conversion control signals, and blue-channel conversion control signals with different levels, and respectively output the red-channel conversion control signals, green-channel conversion control signals, and blue-channel conversion control signals with different levels to the red, green, and blue lamps to be driven.

[0031] In the present utility model, the control signals of the red, green, and blue channels are integrated into a dislocation control signal. The dislocation control signal carries the control information of the red, green, and blue lamps in the form of a dislocation voltage. After being transmitted through the two-wire transmission module 11, the voltage discrimination unit on the lamp module 12 distinguishes the control signals of the red, green, and blue channels on the dislocation control signal. Finally, the distinguished control signals of the red, green, and blue channels are respectively used to drive the red, green, and blue lamps. A discrimination function is added to the analysis unit 121 in the lamp module 12 to realize the transmission of the two-wire control signal, and there is no need to access the lamp through a four-wire system to control the lamp.

[0032] The two-wire transmission module includes a main branch line a2 and a main branch line b14; the input end of the lamp module is provided with a branch line a1 and a branch line b13; a piercing buckle 0 is provided between the branch line a1 and the main branch line a2, the branch line b13, and the main branch line b14. Refer to Figure 2 and Figure 4As shown, the piercing buckle 0 includes a first housing 3 and a second housing 4 that is rotatably connected to the first housing 3 through a rotating shaft 6. A groove 31 for accommodating the main branch line a2 or the main branch line b14 is provided in the first housing 3. A plurality of mutually insulated piercing pieces 32 are provided at the groove 31 of the first housing 3. One end of the piercing piece 32 is connected to the branch line a or the branch line b13, and the other end of the piercing piece 32 is set as a sharp tip. The sharp tip is used to pierce the insulating layer of the main branch line a2 or the main branch line b14 when the first housing 3 and the second housing 4 are buckled together.

[0033] Referring to Figure 4 、 Figure 5 , preferably, the ends of the first housing 3 and the second housing 4 away from the rotating shaft 6 are set as a buckling structure. The buckling structure 5 includes a buckle head 51 and a buckle groove 52 adapted to the buckle head 51. The buckle head 51 and the buckle groove 52 are respectively provided on the first housing 3 and the second housing 4.

[0034] Preferably, the first housing 3 and the second housing 4 are respectively set as a square-like housing and an "L"-shaped hook housing for buckling connection. The "L"-shaped hook housing includes a long handle portion 41 and a short handle portion 42. One end of the long handle portion 41 is rotatably connected to one end of the square-like housing. The buckle head 51 or the buckle groove 52 is provided on the side wall of the short handle portion 42 near one end of the long handle portion 41, and the adapted buckle groove 52 or the buckle head 51 is provided on the side wall of the square-like housing near the short handle portion 42.

[0035] Referring to Figure 5 、 Figure 7 and Figure 9 , specifically, in this application, the first housing 3 is a square-like housing, and the second housing 4 is an "L"-shaped hook housing. It should be noted that the first housing 3 includes a first housing main body 35 and extension plates 36 provided at the ends in the length direction of the first housing main body 35 and extending away from the first housing main body 35. Rotating holes 37 are respectively provided at one side ends of the two extension plates 36. A through hole 43 is provided at the end of the long handle portion 41 of the second housing 4 away from the short handle portion 42. The rotating shaft 6 passes through the through hole 43 and both ends extend out of the through hole 43. The rotating shaft 6 extending out of the through hole 43 is inserted into the two rotating holes 37, realizing the rotatable connection between the first housing 3 and the second housing 4.

[0036] Referring to Figure 6, in this application, on one side of the two extension plates 36 close to the rotation hole 37, there are a pair of opposite notches 38, and the two notches 38 and a recessed groove 39 formed by a surface of the first housing body 35 close to the extension plate 36 and recessed from the surface opposite to this surface constitute the groove 31.

[0037] Refer to Figure 9 , preferably, the end section of the short handle part 42 of the second housing 4 is provided with an arc-shaped notch 33, and the arc-shaped notch 33 is recessed from the side close to the long handle part 41 to the side away from the long handle part 41, and the cross-section of this arc-shaped notch is similar to a trapezoidal structure or a triangular structure. When it is necessary to open the first housing 3 and the second housing 4, the user only needs to buckle the position of the arc-shaped notch 33 and apply force to disconnect the connection between the first housing 3 and the second housing 4, and then the first housing 3 and the second housing 4 can be opened.

[0038] Preferably, the buckle groove and the buckle head are respectively arranged on the opposite surfaces when the first housing 3 and the second housing 4 are buckled. During installation, the user only needs to press the first housing 3 and the second housing 4 to buckle the buckle head into the buckle groove, which realizes the firm buckle connection between the first housing 3 and the second housing 4. When adopting the above structure with the buckle groove and the buckle head opposite to each other, the first housing 3 can be set as a quasi-square structure, and the second housing 4 can also be set as a square sheet structure.

[0039] Refer to Figure 5 , preferably, a plurality of first partition bars 310 are arranged in the groove 31 of the first housing 3, and second partition bars 44 are arranged at positions corresponding to the first partition bars 310 on the second housing 4. The arrangement of the first partition bars 310 and the second partition bars 44 further isolates and fixes each main branch line a2 and main branch line b14, improves the insulation performance of the entire connection device, and reduces the risk of short circuit. At the same time, the arrangement of the first partition bars 310 and the second partition bars 44 also makes the installation of the main branch line a2 or the main branch line b14 in the groove 31 more stable, not prone to movement or distortion, thereby ensuring the stability of the electrical connection.

[0040] Refer to Figure 5 and Figure 8, preferably, one end of the piercing piece 32 away from the sharp tip is disposed on a PCB board 7, and the PCB board 7 is connected to the branch line a1 or the branch line b13. In this embodiment, the PCB board 7 is disposed at the bottom of the groove 31 of the first housing 3, and the branch line a1 or the branch line b13 is disposed in the first housing 3 and extends from one end of the first housing 3 away from the rotating shaft 6. In the present application, in order to facilitate the buckling of the second housing 4, the middle position of the short handle portion 42 of the second housing 4 is provided with a "U" - shaped card slot 53. When the first housing 3 is buckled with the second housing 4, the card slot 35 is buckled outside the branch line a1 or the branch line b13,

[0041] Refer to Figure 8 , preferably, the sharp tip is provided with a "V" - shaped structure. The "V" - shaped structure enables the sharp tip to have stronger penetration and cutting ability when piercing the insulating layer of the main branch line a2, improving the reliability of the connection. At the same time, the sharp tip with a "V" - shaped structure can better adapt to different diameters of the main branch line a2, reducing damage to the inside of the main branch line a2 or the main branch line b14 during the piercing process and improving the safety of the connection.

[0042] The present utility model provides a two - wire lamp control system with a piercing buckle. By placing the main branch line a2 or the main branch line b14 in the groove of the first housing 3, then pressing the ends of the first housing 3 and the second housing 4 away from the rotational connection, the first housing 3 and the second housing 4 complete the buckling, so that the main branch line a2 or the main branch line b14 is squeezed by the first housing 3 and the second housing 4, and the insulating layer of the main branch line a2 or the main branch line b14 is pierced by the piercing piece, thereby completing the connection between the main branch line a2 and the branch line a1, and between the main branch line b14 and the branch line b13. Therefore, through this piercing buckle 0, the rapid connection between the lamp module and the two - wire transmission circuit in the two - wire lamp system can be realized through a simple pressing action, and the connection is firm and not easy to come off, greatly improving the installation efficiency of the two - wire lamp system and reducing the complexity and error of manual operation.

[0043] At the same time, the piercing buckle 0 can be installed at any position of the main branch line a2 or the main branch line b14, facilitating the installer to select a suitable position for installation. At the same time, the main branch line a2 or the main branch line b14 is disposed between the first housing 3 and the second housing 4, which can contact less air and has a better airtight and waterproof effect.

[0044] Preferably, refer to Figure 1As shown, the offset signal conversion module 9 includes a processor 91, a three-way switch circuit 92, and a two-wire transmission circuit 93. The processor 91 is electrically connected to the central controller 8 and is respectively connected to the three-way switch circuit 92. The two-wire transmission circuit 93 is electrically connected to the central controller 8 and the three-way switch circuit 92 respectively. The processor 91 is used to control the three-way switch circuit 92 to sequentially output a red-channel conversion control signal, a green-channel conversion control signal, and a blue-channel conversion control signal according to the signal states of the original red-channel control signal, the original green-channel control signal, and the original blue-channel control signal, and input them into the voltage stabilization module 10 through the two-wire transmission circuit 93. The voltage stabilization module 10 includes a red-channel voltage stabilization circuit, a green-channel voltage stabilization circuit, and a blue-channel voltage stabilization circuit. The red-channel voltage stabilization circuit, the green-channel voltage stabilization circuit, and the blue-channel voltage stabilization circuit are respectively used to stabilize the red-channel conversion control signal, the green-channel conversion control signal, and the blue-channel conversion control signal to obtain a red-channel control signal, a green-channel control signal, and a blue-channel control signal, and then combine them into the offset control signal and transmit it through the two-wire transmission circuit 11.

[0045] The signal states are specifically high level and low level, or the signal states are specifically having a signal and having no signal. It can be understood that the signal states of red, green, and blue are distinguished by high level / having a signal and low level / having no signal. In an actual circuit, the color or brightness to be output by a lamp can be controlled by high and low levels or by the presence or absence of a signal. The difference is that the judgment methods of high and low levels and the presence or absence of a signal are not exactly the same. Therefore, both high and low levels and the presence or absence of a signal are the control information carried by the signal state. Here, the signal state can be understood as judging whether to output a conversion control signal based on the control information carried by the signal state.

[0046] Further, in some embodiments, the signal states of the original red-channel control signal, the original green-channel control signal, and the original blue-channel control signal are collected according to a collection period, and the single output period is equal to the collection period. It can be combined with Figure 3 , in this case, both the collection period and the output period are fixed. For example, both the collection period and the output period are set to 9 microseconds.

[0047] Even further, combined with Figure 3, when the signal states of the red original control signal, the green original control signal, and the blue original control signal are all high level / have signals, the misalignment control signal is composed of the red control signal, the green control signal, and the blue control signal with different levels from each other. Among them, the proportions of the red control signal, the green control signal, and the blue control signal in the misalignment control signal are each 1 / 3. When the signal states of two of the red original control signal, the green original control signal, and the blue original control signal are high level / have signals, the misalignment control signal is composed of the two control signals corresponding to the two original control signals with high level / have signals. Among them, the proportions of the two control signals corresponding to the two original control signals with high level / have signals in the misalignment control signal are each 1 / 2. When only one of the signal states of the red original control signal, the green original control signal, and the blue original control signal is high level / has a signal, the control signal corresponding to the high level of the signal state of this original control signal is the misalignment control signal.

[0048] It can be understood that the original control signal is collected once every acquisition cycle time. For the valid original control signal collected this time, three conversion control signals need to be output in sequence respectively to complete the conversion and output of the signal. Since misaligned output is required, after the acquisition in each acquisition cycle is completed, the simultaneously collected original control signals need to be converted and then output based on different times to form misaligned output. Since the human eye has the phenomenon of visual persistence, the visual persistence time of the human eye is about 0.2 seconds, and the signal conversion processing in this method is at the microsecond level, so we can't feel the lamp flickering. Although the form of the original PWM signal changes when it finally reaches the lamp, the output effect remains unchanged.

[0049] In some embodiments, in combination with Figure 1 and Figure 3 , the red conversion control signal, the green conversion control signal, and the blue conversion control signal respectively pass through the red voltage stabilizing circuit, the green voltage stabilizing circuit, and the blue voltage stabilizing circuit to obtain the red control signal, the green control signal, and the blue control signal with different levels. Among the red control signal, the green control signal, and the blue control signal with different levels, the level of the blue control signal is 9V, the level of the green control signal is 8V, and the level of the red control signal is 6V.

[0050] In some embodiments, in combination with Figure 2, the parsing unit 121 discriminates the misaligned control signal specifically as follows: when the level of a segment of misaligned control signal is lower than A, this segment of misaligned control signal is discriminated as a red path control signal; when the level of a segment of misaligned control signal is higher than B and lower than C, this segment of misaligned control signal is discriminated as a green path control signal; when the level of a segment of misaligned control signal is higher than D, this segment of misaligned control signal is discriminated as a blue path control signal. Here, in this specific embodiment, the values of A, B, C, and D can be defined according to the levels of the actual control signals or can be judged based on range values. For example, when the voltage value of a segment of misaligned control signal is between 6V and 6.8V, this segment of misaligned control signal is discriminated as a red path control signal; when the voltage value of a segment of misaligned control signal is higher than 6.8V and between 8V and 8.2V, this segment of misaligned control signal is discriminated as a green path control signal; when the voltage value of a segment of misaligned control signal is between 9V and 9.1V, this segment of misaligned control signal is discriminated as a blue path control signal. Since there is a certain fluctuation in the transmission of the control signal, range values can be set for discrimination. The parsing unit 121 discriminates the misaligned control signal according to the above method to obtain red path conversion control signals, green path conversion control signals, and blue path conversion control signals with different levels respectively, and outputs the red path conversion control signals, green path conversion control signals, and blue path conversion control signals with different levels to the red, green, and blue three-way lighting fixtures to be driven respectively.

[0051] The present utility model integrates the control signals of the red, green, and blue three paths into a misaligned control signal. This misaligned control signal carries the control information of the red, green, and blue three-way lighting fixtures in the form of misaligned voltage. After two-wire transmission, the voltage discrimination function on the parsing unit 121 is used to distinguish the control signals of the red, green, and blue three paths on the misaligned control signal. Finally, the distinguished control signals of the red, green, and blue three paths are respectively used to drive the red, green, and blue three-way lighting fixtures. Different from the existing lighting control system, this transmission method only requires a two-wire system to execute after merging the controls. Moreover, the merged misaligned control signal can maintain voltage output during the two-wire system transmission process. The extended access devices will not cause data loss due to abnormal power supply when the control is at a low level or there is no signal, which provides support for system expansion. Finally, this solution can also support the transformation of the existing four-wire control system. Only a controller or converter with the same function as the misaligned conversion signal module 9 needs to be connected to the input end of the four-wire control system to execute the function of the misaligned conversion signal module 9. Then, the output end of the controller or converter can extend and access the subsequent lighting fixture module 12 in the form of a two-wire system. While realizing lighting control, the transformation cost of the existing lighting system can be significantly reduced. At the same time, the design of the new system can also reduce the wiring cost, usage cost, and maintenance cost.

[0052] Embodiment 2:

[0053] Embodiment 2 is substantially the same as Embodiment 1, except that a plurality of mutually insulated piercing pieces are provided on the second housing. During use, by placing the main branch line in the groove of the first housing, then pressing the ends of the first housing and the second housing away from the rotational connection, the buckle is engaged in the buckle groove. At this time, the piercing pieces on the second housing pierce the insulating layer of the main branch line due to the pressure between the first housing and the second housing, thereby completing the connection between the main branch line and the branch line.

[0054] The above-disclosed are only several preferred embodiments of the present utility model. Of course, the scope of rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
