Description

Technical Field

[0001] The utility model belongs to the technical field of stage lamps, and in particular relates to an electrical connection mechanism for a LED combined light source of a stage lamp. Background Art

[0002] Stage lights, as professional lighting equipment in the performing arts industry, play an important role in various performances and light shows. As an important light source for stage lamps, LED light sources are widely used in stage lamps and are very popular in the market because of their many advantages such as high luminous efficiency, good combination rendering effect, energy saving and environmental protection, and long service life.

[0003] At present, stage lighting tends to develop in the direction of miniaturization, lightness, intelligence, and comprehensive functions. Many stage lighting fixtures, especially LED stage lighting fixtures, maximize the number of LED auxiliary combination light sources close to the light outlet of the lighting fixture. This LED auxiliary combination light source is composed of dozens or hundreds of LED lamp beads arranged and combined. With circuit drive and software design, it can independently control a single LED lamp bead, or control multiple LED lamp beads in groups, to achieve different combination effects to meet the needs of the stage or performance. However, this auxiliary combination light source has a significant limitation: in a limited space, the connection of power and control signals requires a large number of directly connected wires. A large number of wires not only take up too much space, but also become particularly cumbersome and difficult to connect when the lighting fixture is zoomed or moved.

[0004] Therefore, it is urgent to provide an electrical connection mechanism for a stage light LED combination light source to solve the deficiencies in the above-mentioned prior art. Summary of the invention

[0005] In view of the problems in the related art, the utility model proposes an electrical connection mechanism for an LED light source of a stage lamp, so as to solve the technical problems of the existing stage lamps such as complicated wires and excessive space occupied when realizing the connection of power and control signals.

[0006] The technical solution of the utility model is implemented as follows: an LED light source electrical connection mechanism for a stage light, comprising an auxiliary light emitting board, an auxiliary light adapter board and an auxiliary light driving board arranged in sequence; the auxiliary light emitting board comprises a light emitting substrate, a light emitting module and a plurality of spring pin connectors are arranged on the light emitting substrate, and each spring pin connector is electrically connected to the light emitting module through the light emitting substrate;

[0007] The auxiliary light adapter board includes an adapter substrate; the adapter substrate is provided with electrical connection contacts corresponding to each spring pin connector, and the auxiliary light emitting board forms an electrical connection through the abutment cooperation between each spring pin connector and the corresponding electrical connection contacts; the adapter substrate is also provided with a plurality of plug sockets, and the plug sockets are electrically connected to each electrical connection contact through the adapter substrate; each plug socket is connected to the auxiliary light driving board through a corresponding plug wire.

[0008] The utility model configures a spring pin connector on the auxiliary light emitting board, and realizes the connection of power and control signals through the full abutment of the spring pin connector with the electrical connection contacts, simplifies the laying of wires, and effectively reduces the use of connecting wires; in addition, the power and control signal connections are realized through the spring pin connector, which can be independently and quickly disassembled without the need for plugging and unplugging wires, and the installation space utilization rate is higher.

[0009] As a further improvement of the above solution, the auxiliary light emitting board is located above the auxiliary light adapter board, the electrical connection contacts are arranged on the upper surface of the auxiliary light adapter board, and the spring pin connector is arranged opposite to the corresponding electrical connection contacts. The spring pin connector is arranged opposite to the electrical connection contacts, so that the LED light source does not need to excessively pursue high-precision alignment during the assembly process, thereby improving the assembly efficiency. At the same time, if maintenance or replacement of parts is required in the future, the spring pin connector can also provide convenient disassembly and reinstallation.

[0010] As a further improvement of the above scheme, the auxiliary light emitting board is a strip structure, and at least one end of the auxiliary light emitting board is provided with an electrical connection portion, and the electrical connection portion is centrally provided with the spring pin connector. By adopting the strip structure of the auxiliary light emitting board, the light source can be effectively extended in the length direction while maintaining a small width and height, thereby significantly reducing the space occupied on the horizontal or vertical plane. In addition, the spring pin connector is centrally arranged at one end of the light emitting board, which further saves space and makes the entire design more compact.

[0011] As a further improvement of the above solution, the auxiliary light emitting panels have multiple electrical connection parts, which are close to each other and placed together above the auxiliary light adapter board. The centrally arranged spring pin connector can greatly simplify the wiring process and reduce the clutter and entanglement of cables. The installer only needs to pay attention to the connection points of the electrical connection parts, and does not need to perform complicated connection operations at multiple locations, thereby improving the installation efficiency.

[0012] As a further improvement of the above scheme, it also includes a mounting frame and a main light source zoom optical lens group;

[0013] The mounting frame is provided with a plurality of light exit holes in an array, and a space for installing the auxiliary light emitting panel is formed between two adjacent light exit holes; the main light source zoom optical lens group includes a plurality of optical lens units, and the optical lens units are matched with the light exit holes. By combining the mounting frame and the main light source zoom optical lens group, an integrated design of the light source and the lens is realized. The system's integration and compactness are effectively improved, making the entire stage light source system more portable, easy to install and deploy.

[0014] As a further improvement of the above scheme, the spring pin connector includes a needle seat, a compression spring and a needle head; one end of the needle seat is fixedly connected to the light-emitting substrate, and the other end is elastically connected to the needle head through the compression spring. Due to its spring characteristics, the spring pin connector can compensate for displacement changes caused by assembly, temperature changes or other environmental factors to a certain extent. This ensures that even in the case of slight vibration or thermal expansion and contraction, the spring pin connector and the electrical connection contact can still maintain good contact, thereby improving the stability of the electrical connection.

[0015] As a further improvement of the above scheme, a sleeve portion is provided at one end of the needle holder away from the light-emitting substrate; the sleeve portion has a hollow inner cavity, and a needle hole is provided at the extended end of the sleeve portion, and the needle hole and the inner cavity are connected to each other; the compression spring is placed in the inner cavity, and part of the needle head extends into the inner cavity; the compression spring is sleeved on the outer periphery of the needle head to provide the needle head with a spring force toward the auxiliary light adapter plate; a limit block is provided at the other end of the needle head, and the diameter of the limit block is larger than the needle hole, so that the needle head cannot completely pass through the needle hole. By designing a single sleeve portion structure to integrate the accommodating space of the inner cavity, the needle hole and the spring, the overall structure is simplified and the manufacturing cost is reduced; at the same time, the connection between the needle holder, the compression spring and the needle head makes maintenance and replacement easier. Once a fault occurs or a component needs to be replaced, the problem can be quickly and accurately located and repaired or replaced.

[0016] As a further improvement of the above scheme, the end of the needle head facing the auxiliary light adapter plate is a spherical structure, and the electrical connection contact is a disc structure, and the diameter of the electrical connection contact is 1.5 to 3.5 times the diameter of the end of the needle head. Since the electrical connection contact is designed as a disc structure and its diameter is larger than the diameter of the end of the needle head, this significantly increases the contact area between the two. A larger contact area means a more uniform pressure distribution, thereby reducing the poor contact phenomenon caused by excessive or insufficient local pressure and improving the stability of the electrical connection. In addition, the spherical structure of the needle head end can adapt to slight offsets or misalignments to a certain extent, thereby avoiding poor contact or circuit breakage caused by misalignment.

[0017] As a further improvement of the above solution, the auxiliary light emitting board and the auxiliary light adapter board are parallel to each other, and the spring pin connector is vertically arranged between the auxiliary light emitting board and the auxiliary light adapter board. The vertically arranged spring pin connector also helps to optimize the wiring structure. The traditional horizontal wiring method may be limited by space, resulting in complex wiring and difficult management. The vertically arranged spring pin connector can reduce the crossing and overlapping of cables, making the connection between the auxiliary light emitting board and the auxiliary light adapter board more concise and orderly, further reducing space occupancy.

[0018] As a further improvement of the above solution, the light emitting module includes a plurality of LED lamp beads, and the LED lamp beads are arranged and distributed at intervals along the extension direction of the light emitting substrate.

[0019] Beneficial effects of the utility model:

[0020] The utility model configures a spring pin connector on the auxiliary light emitting board, and realizes the connection of power and control signals through the full abutment of the spring pin connector with the electrical connection contacts, simplifies the laying of wires, and effectively reduces the use of connecting wires; in addition, the power and control signal connections are realized through the spring pin connector, which can be independently and quickly disassembled without the need for plugging and unplugging wires, and the installation space utilization rate is higher.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] like Figure 1-Figure 8 As shown, an LED light source electrical connection mechanism for a stage light comprises an auxiliary light emitting board 1, an auxiliary light adapter board 2 and an auxiliary light driving board 3 which are arranged in sequence;

[0041] The auxiliary light emitting board 1 includes a light emitting substrate 11, on which a light emitting module 12 and a plurality of spring pin connectors 13 are provided, and each spring pin connector 13 is electrically connected to the light emitting module 12 through the light emitting substrate 11. Specifically, a printed circuit can be configured on the light emitting substrate 11, and the spring pin connector 13 is electrically connected to the light emitting module 12 through the printed circuit. In this embodiment, the light emitting module 12 includes a plurality of LED lamp beads 121, and the LED lamp beads 121 are arranged and distributed at intervals along the extension direction of the light emitting substrate 11. Specifically, a single light emitting substrate 11 can be configured with 16 to 20 lamp beads, and 4 to 12 spring pin connectors 13 can be configured according to needs.

[0042] The auxiliary light adapter board 2 includes an adapter substrate 21; the adapter substrate 21 is provided with electrical connection contacts 22 corresponding to each spring pin connector 13, and the auxiliary light emitting board 1 forms an electrical connection through the abutment and cooperation between each spring pin connector 13 and the corresponding electrical connection contact 22;

[0043] In this embodiment, the auxiliary light emitting board 1 is located above the auxiliary light adapter board 2, the electrical connection contacts 22 are arranged on the upper surface of the auxiliary light adapter board 2, and the spring pin connector 13 is arranged opposite to the corresponding electrical connection contacts 22. The spring pin connector 13 is arranged opposite to the electrical connection contacts 22, so that the LED light source does not need to excessively pursue high-precision alignment during the assembly process, thereby improving the assembly efficiency. At the same time, if maintenance or replacement of parts is required in the future, the spring pin connector 13 can also provide convenient disassembly and reinstallation.

[0044] In this embodiment, the auxiliary light emitting board 1 is a strip structure, and at least one end of the auxiliary light emitting board 1 is provided with an electrical connection portion 14, and the electrical connection portion 14 is centrally provided with the spring pin connector 13. By adopting the strip structure of the auxiliary light emitting board 1, the light source can be effectively extended in the length direction while maintaining a small width and height, thereby significantly reducing the space occupied on the horizontal or vertical plane. In addition, the spring pin connector 13 is centrally arranged at one end of the emitting board, which further saves space and makes the entire design more compact.

[0045] In this embodiment, the auxiliary light emitting panels 1 have multiple electrical connection parts 14, which are close to each other and placed together above the auxiliary light adapter board 2. Specifically, the end of the auxiliary light emitting panel 1 provided with the electrical connection part 14 can be spliced ​​in a "cross" shape. Correspondingly, the structure of the auxiliary light adapter board 2 is also arranged in a "cross" shape, and the electrical connection contacts 22 are distributed along the contour edge of the upper surface of the auxiliary light adapter board 2. The centrally arranged spring pin connectors 13 can greatly simplify the wiring process and reduce the clutter and entanglement of cables. The installer only needs to pay attention to the connection point of the electrical connection part 14, and there is no need to perform complicated connection operations at multiple locations, thereby improving the installation efficiency.

[0046] In this embodiment, the spring pin connector 13 includes a needle seat 131, a compression spring 132 and a needle head 133; one end of the needle seat 131 is fixedly connected to the light-emitting substrate 11, and the other end is elastically connected to the needle head 133 through the compression spring 132. Due to its spring characteristics, the spring pin connector 13 can compensate for the displacement changes caused by assembly, temperature changes or other environmental factors to a certain extent. This ensures that even in the case of slight vibration or thermal expansion and contraction, the spring pin connector 13 and the electrical connection contact 22 can still maintain good contact, thereby improving the stability of the electrical connection.

[0047] In this embodiment, a sleeve portion 1311 is provided at one end of the needle seat 131 away from the light-emitting substrate 11; the sleeve portion 1311 has a hollow inner cavity 1312, and a needle hole 1313 is provided at the extended end of the sleeve portion 1311, and the needle hole 1313 and the inner cavity 1312 are connected to each other; the compression spring 132 is placed in the inner cavity 1312, and part of the needle 133 extends into the inner cavity 1312; the compression spring 132 is sleeved on the outer periphery of the needle 133 to provide the needle 133 with a spring force toward the auxiliary light adapter plate 2; a limit block 1331 is provided at the other end of the needle 133, and the diameter of the limit block 1331 is larger than the needle hole 1313, so that the needle 133 cannot completely pass through the needle hole 1313. By designing a single sleeve portion 1311 structure to integrate the inner cavity 1312, the needle port 1313 and the accommodating space of the spring, the overall structure is simplified and the manufacturing cost is reduced; at the same time, the connection between the needle seat 131, the compression spring 132 and the needle 133 makes maintenance and replacement easier. Once a fault occurs or a part needs to be replaced, the problem can be quickly and accurately located and repaired or replaced.

[0048] Specifically, the spring pin connector 13 includes an initial extension state and a working compression state. When the spring pin connector 13 is in the initial extension state, the compression spring 132 provides a spring force for the needle 133, so that the needle 133 extends along its axial direction; when the spring pin connector 13 is in the working compression state, the spring pin connector 13 and the electrical connection contact 22 can maintain good contact, thereby improving the stability of the electrical connection.

[0049] In this embodiment, the end of the needle 133 facing the auxiliary light adapter plate 2 is a spherical structure, and the electrical connection contact 22 is a disc structure, and the diameter of the electrical connection contact 22 is 1.5 to 3.5 times the diameter of the end of the needle 133. Specifically, it is preferred that the diameter of the electrical connection contact 22 is 2.5 times the diameter of the end of the needle 133. Since the electrical connection contact 22 is designed as a disc structure and its diameter is larger than the diameter of the end of the needle 133, this significantly increases the contact area between the two. A larger contact area means a more uniform pressure distribution, thereby reducing the poor contact phenomenon caused by excessive or insufficient local pressure and improving the stability of the electrical connection. In addition, the end of the needle 133 with a spherical structure can adapt to slight offsets or misalignments to a certain extent, thereby avoiding poor contact or open circuits caused by misalignment.

[0050] In this embodiment, the auxiliary light emitting board 1 and the auxiliary light adapter board 2 are parallel to each other, and the spring pin connector 13 is vertically arranged between the auxiliary light emitting board 1 and the auxiliary light adapter board 2. The vertically arranged spring pin connector 13 also helps to optimize the wiring structure. The traditional horizontal wiring method may be limited by space, resulting in complex wiring and difficult management. The vertically arranged spring pin connector 13 can reduce the crossing and overlapping of cables, making the connection between the auxiliary light emitting board 1 and the auxiliary light adapter board 2 more concise and orderly, and further reducing space occupancy.

[0051] The transfer substrate 21 is also provided with a plurality of plug sockets 23. Specifically, the plug sockets 23 are arranged on the lower surface of the transfer substrate 21, and the plug sockets 23 are electrically connected to each electrical connection contact 22 through the transfer substrate 21; specifically, a printed circuit can be configured on the transfer substrate 21, and the electrical connection between the electrical connection contact 22 and the plug sockets 23 is realized through the printed circuit. Each plug socket 23 is connected to the auxiliary light driving board 3 through a corresponding plug wire (not shown in the figure). The auxiliary light driving board 3 is provided with a power interface and a signal interface, the power interface is used to connect an external power supply, and the signal interface is used to connect a signal source component.

By combining the mounting frame 4 and the main light source zoom optical lens group 5, an integrated design of the light source and the lens is realized. The integration and compactness of the system are effectively improved, making the entire stage light source system more portable, easy to install and deploy.
