Description

Technical Field

[0001] This utility model relates to the field of track lighting technology, specifically to a low-voltage track constant current drive module and track light that can be controlled in segments. Background Technology

[0002] Track lights need to be installed on matching track strips. Inside the track strip, on each side, there is a conductive strip: one neutral wire and one live wire. These two metal strips are connected to the light fixture's control switch or power plug via wires. The track light's connector has a conductive metal plate. During installation, the conductive metal plate on the track light connector contacts the conductive strip inside the track strip, forming a closed circuit and energizing the track light. Some track lights use multiple conductive strips of the same length as the track groove arranged side-by-side inside the track to form multiple circuits, enabling multi-channel control.

[0003] These types of track lights typically have a constant current drive module at the connector. This module usually has two copper contacts, one for live wire and one for neutral wire on the track. The constant current drive module converts the low-voltage DC power supplied by the live and neutral wires inside the track into a stable current to drive the lamp head. When the track has multiple circuits, connecting the track light to another circuit requires manually removing it from the track, reinstalling it, and then connecting the two copper contacts of the constant current drive module to the other circuit. This makes switching track light circuits very inconvenient. Utility Model Content

[0021] Please refer to Figure 1 and Figure 2 , Figure 1 This is a 3D view of a segmented control low-pressure rail constant current drive module. Figure 2This is an exploded view of a segmented control low-voltage rail constant current drive module. This embodiment provides a segmented control low-voltage rail constant current drive module, comprising a housing 1, a constant current control chip 2, a segmented switch 3, and at least two sets of conductive connectors. A receiving space 10 is formed within the housing 1, and the constant current control chip 2, the segmented switch 3, and the at least two sets of conductive connectors are all located within the receiving space 10 of the housing 1. At least two sets of conductive connectors 4 are respectively disposed on opposite inner sides of the housing 1, with one end of each set of conductive connectors 4 exposed outside the housing 1. One end of the segmented switch 3 is exposed outside the housing 1, and the segmented switch 3 is electrically connected to each set of conductive connectors 4 and the constant current control chip 2, respectively. The segmented switch 3 is used to connect any set of conductive connectors 4 to the constant current control chip 2. In this example, the constant current control chip 2 is model BK-BET030-A0800A.

[0022] In practical use, each set of conductive connection components 4 is used to contact a set of neutral and live wires installed in the track, so that each set of conductive connection components 4 is connected to a set of neutral and live wire circuits respectively. The segment switch 3 is used to switch the conduction circuit of any set of conductive connection components 4 and constant current control chip 2. When one set of conductive connection components 4 is connected to constant current control chip 2 through segment switch 3, the electrical signal of the neutral and live wires connected to the conductive connection component passes through the conductive connection component 4 and segment switch 3 in sequence, and then is input into constant current control chip 2. Constant current control chip 2 constants the current of the input electrical signal and outputs it to the LED light to power the LED light. By toggling segment switch 3, different conductive connection components 4 are connected, making the live and neutral wires corresponding to the conductive connection component 4 connected, thereby switching the connection of constant current control chip 2 to different circuits. The segmented controllable low-voltage rail constant current drive module in this example has two sets of conductive connection components 4. These two sets of conductive connection components 4 are electrically connected to a segment switch 3 via wires. The segment switch 3 is used to switch either set of wire connection components to be connected to the constant current control chip 2. Thus, by simply toggling the control switch, the segmented controllable low-voltage rail constant current drive module can be connected to different circuits in the rail.

[0023] Please refer to Figure 2 and Figure 3 , Figure 3This is a schematic diagram of the PCB board 32. Further, the segmented switch 3 includes a toggle switch 31 and the PCB board 32. The PCB board 32 has at least two sets of input pads 321, one set of toggle switch pads 322, and one set of output pads 323. During connection, the pins of the toggle switch 31 are soldered to the toggle switch pads 322 of the PCB board 32. Each set of input pads 321 is electrically connected to a set of conductive connection components 4 via wires. The output pads 323 of the PCB board 32 are electrically connected to the constant current control chip 2 via wires. In this example, the PCB board 32 has two sets of input pads 321, one set of toggle switch pads 322, and one set of output pads 323. Each set of input pads 321 is electrically connected to a set of conductive connection components 4 via wires. The toggle switch 31 is a double-pole double-position toggle switch 31.

[0024] Furthermore, each conductive connection assembly 4 includes a positive copper plate 41 and a negative copper plate 42, which are respectively disposed on opposite sides of the housing 1, with one end of the positive copper plate 41 and the negative copper plate 42 exposed outside the housing 1 to facilitate contact with the live wire and neutral wire on the rail lamp. The other ends of the positive copper plate 41 and the negative copper plate 42 are electrically connected to the sectionalizing switch 3 via wires.

[0025] In practical applications, the positive copper plate 41 is connected to the live wire of the track light, and the negative copper plate 42 is connected to the neutral wire of the track light. Both the positive and negative copper plates 41 and 42 are electrically connected to the sectionalizing switch 3 via wires, thus connecting the sectionalizing switch 3 to the live and neutral wires of the track light. In this example, the positive and negative copper plates 41 and 42 have the same shape.

[0026] In this example, at least two openings 100 are provided on each of the opposite sides of the outer casing 1. The positive copper plate 41 and the negative copper plate 42 of each set of conductive connection components 4 are respectively disposed on the opposite sides of the outer casing 1. One end of the positive copper plate 41 passes through the outer casing 1 through the opening 100 on one side of the outer casing 1, and one end of the negative copper plate 42 passes through the outer casing 1 through the opening 100 on the other side of the outer ear.

[0027] The outer cover includes an upper cover 11 and a housing 12, wherein the housing 12 is hollow inside, and the upper cover 11 is placed on the housing 12. After the upper cover 11 is placed on the housing 12, an accommodating space 10 is formed between the upper cover 11 and the housing 12. Each set of conductive connection components 4 is disposed on opposite sides of the housing 12, and each set of conductive connection components 4 is exposed through the opening 100.

[0028] In this example, the housing 12 has four openings 100, two of which are located on one side of the housing 12 and the other two on the other side. The positive copper plate 41 of each conductive connection assembly 4 is located on one side of the housing 12, with one end of the positive copper plate 41 exposed outside the housing 12. The negative copper plate 42 of each conductive connection assembly 4 is located on the other side of the housing 12, with one end of the negative copper plate 42 exposed outside the housing 12. The positive and negative copper plates 41 and 42 of each conductive connection assembly 4 are at the same height relative to the bottom of the housing 12, ensuring that when the segmented controllable low-voltage constant current drive module is connected to the track light, each conductive connection assembly 4 is connected to a set of live and neutral wires within the track light.

[0029] Furthermore, two openings 100 on the same side of the housing 12 are spaced apart along the length of the housing 12, and the two openings 100 are at different heights relative to the bottom of the housing 12, so that each set of conductive connection components 4 corresponds to a different circuit in the track.

[0030] To achieve a secure connection between the top cover 11 and the housing 12, at least one snap-fit ​​interface 121 is provided on each of the opposite sides of the housing 12, and at least one snap fastener 111 is provided on each of the opposite sides of the top cover 11. During connection, each snap fastener 111 is engaged with a snap-fit ​​interface 121. In this example, two snap-fit ​​interfaces 121 are provided on each of the opposite sides of the housing 12, and the two snap-fit ​​interfaces 121 are spaced apart. Two snap fasteners 111 are provided on each of the opposite sides of the top cover 11, and each snap fastener 111 is engaged with a snap-fit ​​interface 121, making the top cover 11 and the housing 12 detachably connected, which facilitates the assembly of the constant current drive module.

[0031] This utility model also provides a track light, which includes the above-mentioned segmentally controllable low-voltage track constant current drive module.

[0032] In summary, by setting at least two sets of conductive connection components 4 and switching the constant current control chip 2 to any set of conductive connection components 4 through segmented control switches, the constant current control chip 2 can switch between different circuits of track output in the track light by switching its connection with different conductive connection components 4, which greatly improves the efficiency of track light switching circuits.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
