Description

Technical Field

[0001] This utility model belongs to the field of linear light technology, and specifically relates to a track head with multi-line switch control. Background Technology

[0002] In the lighting field, track lights are widely used in commercial spaces, exhibition venues, and other scenarios due to their flexible installation and outstanding lighting effects. As users' demands for comfortable lighting environments increase, track lights with color temperature adjustment functions have become the market mainstream. However, existing color temperature switching solutions for track lights have many drawbacks, becoming a problem that the industry urgently needs to solve.

[0003] Traditional track light color temperature control often employs an "independent controller + multiple sets of wiring" approach: multiple sets of wires (each corresponding to a different color temperature mode) need to be laid between the track light and the power supply, and switching is achieved by sending electrical signals through an external controller. This approach has three main drawbacks: First, the wiring layout is cumbersome—multiple sets of wires need to be laid separately and insulated, resulting in long construction periods, high labor costs, and a risk of short circuits due to intertwined wiring; second, user operation is complex—the controller usually requires a remote control or touch panel, which is not user-friendly for the elderly and children, and professional repairs are required when the equipment malfunctions, leading to high maintenance costs; third, control accuracy is low—the electrical signal transmission is susceptible to electromagnetic interference, causing delays or false triggers in color temperature switching, affecting the lighting experience.

[0004] In addition, some products have attempted to optimize their performance through an intelligent solution that combines a built-in microcontroller and sensors. However, the high cost of electronic components has driven up the price of the products and limited their market penetration. Furthermore, the integration of electronic components inside the lamps can lead to component aging when heat dissipation is poor, further reducing product reliability.

[0005] In summary, existing technologies for track light color temperature switching suffer from core problems such as complex circuitry, inconvenient operation, high cost, and poor stability. There is an urgent need for a simplified and user-friendly control solution to meet the market's demand for efficient and economical color temperature adjustment. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a track head with multi-line switch control. Through mechanical structure optimization, the combination of DIP switch device and three-color temperature power supply wire layout achieves convenient operation and system simplification for track light color temperature switching.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows: a track head with multi-line switch control, comprising:

[0008] A housing assembly, comprising a first housing and a second housing that can be interlocked; a cavity is provided between the first housing and the second housing; and a cutout portion is provided on the housing assembly.

[0009] A track head switch, wherein the track switch can be snapped into the hollowed-out portion;

The first color temperature power supply wire is connected to the first connecting wire, and the second color temperature power supply wire and the third color temperature power supply wire are connected to the DIP switch assembly through connecting wires.

[0013] Compared to existing technologies, the advantages of this invention are as follows: The multi-line switch-controlled track head proposed in this invention can be quickly connected to lighting fixtures. The first and second power output terminals are located in the power distribution module inside the track head. After obtaining power from the main power supply, the power is rectified and regulated by the internal circuit to provide a stable operating voltage for the light source.

One end of multiple color temperature power supply wires is connected to the contact group inside the track head through crimp terminals or welding, and the other end is inserted into the color temperature control module of the light source (such as the multi-module power supply interface of LED beads). The three sets of wires correspond to the three color temperature modes of the light source, and color temperature switching is achieved through on / off combinations. Users can switch colors simply by toggling the DIP switch assembly on the side of the track head. Each action of the DIP switch assembly corresponds to a preset on / off combination of contacts. The physical contact of mechanical contacts replaces traditional electrical signal control, ensuring that there is no signal delay or interference during the switching process.

[0014] The aforementioned track head includes a first connecting wire and a second connecting wire, wherein the first connecting wire is connected to the second color temperature power supply wire, and the second connecting wire is connected to the third color temperature power supply wire.

Detailed Implementation

[0027] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 3This utility model provides a track head with multi-line switch control, including: a housing assembly 100, a track head switch 200, a power output terminal 300, a DIP switch assembly 400, and a multi-color temperature power supply wire 500. The housing assembly 100 includes a first housing 110 and a second housing 120 that can be interlocked. A cavity 130 is provided between the first housing 110 and the second housing 120. The housing assembly 100 has a hollow portion 131. The track switch 200 can be interlocked with the hollow portion 131. The power output terminal 300 includes a first power output terminal 310 and a second power output terminal 320. A power output terminal 310 is connected to a first output wire 140, and a second power output terminal 320 is connected to a second output wire 150; a DIP switch assembly 400 is fixed inside the cavity 130, and the DIP switch assembly 400 is provided with multiple contact groups 410; the multi-color temperature power supply wire 500 includes a first color temperature power supply wire 510, a second color temperature power supply wire 520, and a third color temperature power supply wire 530, the first color temperature power supply wire 510 is connected to a first connecting wire 610, and the second color temperature power supply wire 520 and the third color temperature power supply wire 530 are connected to the DIP switch assembly 400 through the connecting wire 600. The multi-line switch-controlled track head proposed in this utility model can be quickly connected to lighting fixtures. The first power output terminal 310 and the second power output terminal 320 are located in the power distribution module inside the track head. After obtaining power from the main power supply, the power is rectified and regulated by the internal circuit to provide a stable operating voltage for the light source of the lighting fixture. The two sets of output terminals correspond to different color temperature control logics. One end of multiple color temperature power supply wires 500 is connected to the contact group 410 inside the track head through crimp terminals or welding, and the other end passes through the color temperature control module of the light source of the lighting fixture (such as the multi-module power supply interface of LED beads). The three sets of wires correspond to the three color temperature modes of the light source of the lighting fixture, and the color temperature is switched by combination of on and off. The user can switch the color temperature by simply toggling the DIP switch assembly 400 on the side of the track head. Each action of the DIP switch assembly 400 corresponds to a preset combination of on and off contacts. The physical contact of the mechanical contacts replaces the traditional electrical signal control, ensuring that there is no signal delay or interference during the switching process.

[0028] Furthermore, referring to Figure 1 The connecting wire 600 proposed in this application includes a first connecting wire 610 and a second connecting wire 620. The first connecting wire 610 is connected to the second color temperature power supply wire 520, and the second connecting wire 620 is connected to the third color temperature power supply wire 530. The connection relationship between the connecting wire 600 and the color temperature power supply wires 500 is determined, forming a clear and stable current path between the power output terminal 300 and the multi-color temperature power supply wires 500, providing a reliable physical basis for color temperature switching. Furthermore, referring to… Figure 1 and Figure 2The second output wire 150 is connected to the DIP switch assembly 400. By connecting the second output wire 150 (i.e., the power supply line from the second power output terminal 320) to the DIP switch assembly 400, this power path is directly controlled by the mechanical action of the DIP switch, thereby forming a coordinated on / off logic with other color temperature circuits. For example, in a three-position DIP switch design, when switching to the "cool light" position, the DIP switch contacts can simultaneously connect the first connecting wire 610 (supplying neutral light) and the second output wire 150 (supplying cool light), achieving high color temperature mixed lighting; while in the "warm light" position, only the first connecting wire 610 is connected, and the second output wire 150 is disconnected to prevent the cool light LEDs from accidentally lighting up. This design ensures the mutual exclusion or combination between different color temperature modes, eliminating problems such as color temperature mixing and abnormal brightness caused by line crosstalk. More importantly, the controlled connection of the second output wire 150 as an independent power supply branch avoids the efficiency loss and heat generation problems caused by relying on a single power supply for voltage division dimming in traditional solutions, thus improving energy utilization efficiency. Meanwhile, since the second output wire 150 is connected to the DIP switch component 400 inside the track head, only the standardized multi-color temperature power supply wire 500 needs to be led out externally, so that the same track head can be adapted to various brands of lamps, improving the versatility of the product.

[0029] Furthermore, referring to Figure 1 The upper part of the cavity 130 is provided with a fixing plate 132, and the power output terminal 300, the first output wire 140, and the second output wire 150 can be snapped into the fixing plate 132. The fixing plate 132, as an integrated positioning platform, can secure multiple key wires and power terminals together, preventing wires from loosening, making poor contact, or even short circuits due to vibration during transportation, installation, or use. Secondly, the snap-fit ​​fixing eliminates the need for welding or screw tightening, saving production time and avoiding the aging effects of high-temperature welding on insulation materials, thus extending product life. Furthermore, the fixing plate 132 is typically made of flame-retardant engineering plastic, possessing good insulation performance and thermal stability, effectively isolating high-voltage power supply areas from low-voltage control areas, and improving the overall electrical safety level. Of course, this application does not limit the specific structure of the fixing plate 132. Preferably, the fixing plate 132 is provided with a wire clamping groove, and the power output terminal 300, the first output wire 140, and the second output wire 150 can all be snapped into the wire clamping groove. Further, referring to… Figure 3The outer surface of the first housing 110 is provided with a first protrusion 111, on which a DIP switch outlet 112 is provided. The DIP switch assembly 400 can be snapped into the DIP switch outlet 112. The first protrusion 111 raises the DIP switch operation part and makes it protrude from the housing surface, making it easier for the user to operate with their fingers. This is especially suitable for convenient operation when track lights are installed in a high position (such as in a shopping mall ceiling), avoiding the problem of traditional embedded buttons being difficult to reach. Secondly, the size and shape of the DIP switch outlet 112 are precisely matched with the DIP switch assembly 400, ensuring the stability of the DIP switch travel and the tactile feedback during the switching process, while preventing external foreign objects (such as dust and moisture) from seeping into the cavity 130 through gaps, thus improving the protection level. Furthermore, the structure of the first protrusion 111 enhances the local strength of the housing, preventing deformation or cracking of the housing due to frequent operation, and extending the product's service life. Further, referring to... Figure 2 The DIP switch assembly 400 also includes a connecting baffle 420 and a toggle switch 430. The connecting baffle 420 has a contact group 410 and a protruding second boss 421. The toggle switch 430 is fixed to the second boss 421. This multi-layered mechanical structure design is the core of achieving precise and reliable color temperature switching. The connecting baffle 420, as the carrier of the contact group 410, is made of high-rigidity insulating material to ensure that the positions of each contact do not deform during long-term use and maintain stable electrical contact pressure. The protruding second boss 421 provides a stable mounting base for the toggle switch 430, making the switching action more direct and lag-free. The toggle switch 430, fixed to the second boss 421, can rotate or slide synchronously with the user's toggle, precisely aligning with different contact groups 410 to achieve a clear correspondence of "one setting, one color temperature". This mechanical linkage avoids signal drift or program crashes that may occur with electronic encoders, and can still work reliably even in extreme temperature or humidity environments.

[0030] Furthermore, referring to Figure 2The contact group 410 includes a first contact group 411, a second contact group 412, and a third contact group 413. The first contact group 411 is electrically connected to the first connecting line 610, the second contact group 412 is electrically connected to the second connecting line 620, and the third contact group 413 is electrically connected to the second output wire 150. The switch 430 has three positions, which are electrically connected to the first contact group 411, the second contact group 412, and the third contact group 413, respectively. The first contact group 411, the second contact group 412, and the third contact group 413 are also electrically connected to the first connecting line 610, the second connecting line 620, and the second output wire 150, respectively. This electrical connection logic is the technical basis for realizing independent control of multiple color temperatures. By corresponding each contact group 410 with a specific wire, the DIP switch can accurately activate the preset color temperature combination in different positions. For example, when the first contact group 411 is turned on, only the warm light LED is illuminated; when the second contact group 412 is turned on, the neutral light LED is illuminated; and the third contact group 413 is used to activate the cool light or mixed mode. This "one-to-one" or "one-to-many" electrical connection ensures electrical isolation between each color temperature channel, avoiding color shift or flickering problems caused by shared drive circuits in traditional PWM dimming. Simultaneously, since each contact group independently carries one current path, there is no voltage drop due to load aggregation, ensuring brightness consistency across different color temperature modes. Furthermore, this connection method supports flexible color temperature strategy configuration—manufacturers can achieve different mixed color temperature effects by adjusting the wiring logic of contact group 410, such as connecting two wires to the third contact group 413 simultaneously, without changing the hardware structure, thus meeting diverse market demands. Of course, this application does not limit the specific number of contact groups 410. Preferably, the switch 430 has three positions, which are electrically connected to the first contact group 411, the second contact group 412, and the third contact group 413, respectively. This three-position design realizes a user-friendly color temperature selection mechanism. The three physical positions correspond to three typical lighting scenarios (such as warm light 3000K, neutral light 4000K, and cool light 5000K). Users can switch intuitively by tossing left, center, and right, without having to remember complicated operation steps or rely on display prompts. Each position has a clear mechanical stop, producing a clear "click" sound and tactile feedback when tossed, ensuring that the user confirms the successful switch and avoiding flickering or half-brightness of the lamp due to improper operation. The three-position design also supports mutually exclusive switching logic, with only one position active at any given time, preventing energy waste or color temperature confusion caused by multiple color temperature LEDs lighting up simultaneously. In addition, the three-position structure balances functionality and ease of operation; fewer than three positions would not cover the mainstream color temperature requirements.

[0031] Furthermore, referring to Figure 1The cavity 130 contains a wiring groove 160 into which the multi-color temperature power supply wire 500 can be plugged. This structural design significantly improves the standardization of wire connections and assembly efficiency. The wiring groove 160 is typically molded from insulating material and contains multiple independent channels, each corresponding to a color temperature wire. The groove opening size precisely matches the outer diameter of the wire, ensuring a secure and non-loose connection after insertion. This plug-in connection replaces traditional screw terminals or soldering methods. During installation, simply strip the wire and push it into the groove to achieve both electrical conduction and mechanical fixation. Furthermore, the multi-color temperature power supply wire 500 can be connected to an external lighting power supply. As the sole electrical bridge between the track head and the lighting source, the multi-color temperature power supply wire 500 is typically equipped with a standardized plug (such as a GX10Q, MR16 interface, or dedicated quick-connect terminal) at its end, allowing direct insertion into the corresponding color temperature drive module inside the lighting fixture without on-site wiring. This not only achieves efficient installation and flexible upgrades but also promotes the modularization, standardization, and user-friendliness of track lighting systems.
