Description

Technical Field

[0001] This invention relates to the field of supermarket lighting equipment technology, and in particular to a supermarket energy-saving lighting fixture with splicing and expansion functions. Background Technology

[0002] Modular, expandable, energy-saving supermarket lighting fixtures are commercial lighting devices that can be flexibly assembled and moved, and possess highly efficient energy-saving characteristics. These fixtures typically feature a lightweight structural design and are equipped with LED light sources or other energy-saving lamps. They support manual or electric adjustment of the number of fixtures and lighting positions to adapt to changes in shelf layout, promotional area adjustments, and dynamic changes in lighting needs within supermarket environments. Simultaneously, by utilizing low-power technologies such as intelligent dimming and human or light sensor control, they significantly reduce energy consumption while still meeting functional lighting requirements.

[0003] Currently, most common portable lighting systems employ a guide rail structure, such as a track system with a built-in conductive rail. This system forms an electrical circuit through contact with metal terminals at the bottom of the downlight, allowing the lamp to move and position freely on the track. However, this type of electrical contact structure between the conductive rail and the sliding components has significant drawbacks: during long-term use, the metal contact surfaces are prone to oxidation due to exposure to air, or poor contact due to the accumulation of dust and oil in the shopping mall environment, or even wear due to mechanical sliding. These problems all increase contact resistance, and resistance fluctuations can lead to localized overheating and electrical sparks, significantly increasing the safety hazards of electrical fires and arcing short circuits. Furthermore, unstable electrical contact can cause voltage fluctuations in the power supply, resulting in problems such as flickering, uneven brightness, or intermittent extinguishing of the lamps, affecting lighting quality and equipment lifespan, and failing to meet the high standards of reliability and safety required by shopping malls.

[0004] Based on the above situation, there is an urgent need for a new type of splicing and expandable energy-saving lighting solution for supermarkets to solve the problems of low electrical contact reliability, significant safety hazards, and unsatisfactory energy utilization efficiency in existing rail lighting systems. Summary of the Invention

[0005] In order to overcome the shortcomings of existing rail-mounted lighting systems, such as unreliable electrical contact, safety hazards, and low energy efficiency, this invention provides a commercial and supermarket energy-saving lighting fixture with splicing and expansion functions.

[0006] A commercial energy-saving lighting fixture with splicing and expansion functions includes a mounting rail with symmetrically distributed mounting supports at the top. An H-shaped partition is fixed inside the mounting rail. A controller is located in the middle of the top wall of the mounting rail, and symmetrically distributed connecting wires are located inside the controller. Symmetrically distributed outlets are opened on the H-shaped partition to provide passages for the connecting wires. Symmetrically distributed interface bases are slidably connected inside the mounting rail. The movable ends of each connecting wire pass through the outlets and are electrically connected to the adjacent interface base. Several downlight bodies are slidably connected in the horizontal direction in the mounting rail. Each interface base is mechanically fixed and electrically connected to one of the downlight bodies by snap-fit. Adjacent downlight bodies are connected in series by snap-fit.

[0007] Furthermore, each downlight body is provided with a first concave connector, a second concave connector, and a first convex connector on its top and left and right sides. The first concave connector is a dedicated connection interface between the downlight body and the interface base, while the second concave connector and the first convex connector are splicing interfaces between adjacent downlight bodies. The two are connected by a convex-concave fit.

[0008] Furthermore, a connecting assembly is provided between adjacent downlight bodies. The connecting assembly includes a telescopic electrical connecting wire and a third concave connector and a second convex connector at both ends thereon. The third concave connector engages with a first convex connector on the downlight body, and the second convex connector engages with a second concave connector on the downlight body.

[0009] Furthermore, a pressure plate is provided at the bottom of the mounting rail, and screws are threaded onto each downlight body.

[0010] Furthermore, the H-shaped partition is slidably connected to symmetrically distributed carriages, and each carriage is connected to the H-shaped partition by symmetrically distributed springs, which are all wound around the adjacent carriages.

[0011] Furthermore, rotating cylinders are rotatably connected to the crossbars on the opposite sides of the carriages, and the transverse sections of each cable outlet are provided with arc surfaces.

[0012] Furthermore, the bottom of the mounting rail has flared openings near both ends for mounting the downlight body.

[0013] Furthermore, each interface base has a groove on its top to accommodate the connecting wires. Beneficial effects

[0014] This invention achieves rapid assembly and adaptive spacing adjustment of lighting fixtures by using a downlight body with a standardized snap-fit ​​interface and a flexible, retractable electrical connection cable. This design greatly improves the flexibility and installation efficiency of the lighting fixture layout, enabling precise matching of dynamic lighting needs such as supermarket shelf adjustments and promotional area changes. Simultaneously, the stable snap-fit ​​electrical connection effectively avoids the resistance fluctuations, sparks, and power outage risks associated with traditional sliding contacts, significantly improving the reliability and safety of the lighting system.

[0015] This invention, through the cooperation of a sliding carriage, a spring tensioning mechanism, a rotating drum, and an arc-shaped conductor, achieves effective guidance, constant tension protection, and friction optimization for connecting wires, greatly reducing the risk of wire wear and breakage, and ensuring the long-term stability of the power supply circuit. Combined with the mechanical locking design of the screw abutting the pressure plate, it ensures the firmness of the lamp after positioning and avoids displacement caused by external forces. The overall system effectively improves the consistency and reliability of lighting quality, while realizing on-demand expansion and energy-saving control, resulting in significant comprehensive energy-saving effects.

Detailed Implementation

[0025] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] Example 1: A supermarket energy-saving lighting fixture with splicing and expansion function, such as... Figures 1-3 As shown, the installation includes a mounting rail 1 that serves as the overall support and installation foundation. The top of the mounting rail 1 has symmetrically distributed mounting supports 101, which are used to stably fix the mounting rail 1 to the supermarket roof using bolts and other connecting parts, so as to achieve the overall suspended installation and positioning of the lamp. An H-shaped partition 2 is fixedly connected inside the mounting rail 1. Its core function is to divide the cavity inside the mounting rail 1 into two independent spaces, the upper layer for arranging power supply control components and the lower layer for the sliding and installation channel of the lamp, so as to avoid interference between different components. The top wall of the mounting rail 1 has a controller 5 with lighting parameter adjustment function, which can realize the operation of lamp brightness adjustment, switch control and fault monitoring, etc., to meet the lighting needs of different scenarios in the supermarket.

[0027] The controller 5 contains symmetrically distributed connecting wires 6, serving as the carriers of electrical energy. The H-shaped partition 2 has symmetrically distributed outlets, providing passageways for the connecting wires 6 to extend from the upper control area to the lower installation area. Symmetrically distributed interface bases 4 are slidably connected within the lower space cavity of the mounting rail 1, acting as intermediate connecting components between the controller 5 and the downlight body 3. The movable ends of each connecting wire 6 pass through the outlets and electrically connect to the adjacent interface base 4, completing the transmission of electrical energy from the controller 5 to the interface base 4. Each interface base 4 has a groove 401 on its top to accommodate the connecting wires 6, used to store and protect the ends of the connecting wires 6, preventing poor contact due to external impact.

[0028] Several downlight bodies 3 are horizontally slidably connected in the lower cavity of the mounting rail 1. Each interface base 4 is mechanically fixed and electrically connected to one of the downlight bodies 3 by snap-fit. Adjacent downlight bodies 3 are connected in series by snap-fit ​​to ensure that multiple downlight bodies 3 can receive power simultaneously. The bottom of the mounting rail 1 has flared openings 903 near both ends. The function of these openings is to provide a convenient guide channel for the downlight bodies 3 to enter the rail. By enlarging the opening size, it is convenient for operators to quickly snap the downlight bodies 3 into the lower cavity of the mounting rail 1, reducing the difficulty of installation.

[0029] like Figure 4 and Figure 5 As shown, each downlight body 3 has a first concave connector 301, a second concave connector 302, and a first convex connector 303 on its top and left and right sides, respectively. The first concave connector 301 is a dedicated connection interface between the downlight body 3 and the interface base 4. Each interface base 4 has a plug that matches the first concave connector 301. Through the plug-in and plug-out cooperation between the plug and the first concave connector 301, the downlight body 3 and the interface base 4 can be quickly connected and fixed and electrically connected. The second concave connector 302 and the first convex connector 303 are splicing interfaces between adjacent downlight bodies 3. The two are connected by a concave-convex cooperation to form a snap-fit ​​connection. All downlight bodies 3 can be connected in series to form a complete lighting circuit. After being powered by the connecting wire 6, all downlight bodies 3 can be lit synchronously.

[0030] like Figure 5 and Figure 6 As shown, a connecting component with adaptive spacing adjustment function is provided between adjacent downlight bodies 3 to solve the electrical connection problem in the non-tight splicing state and ensure that the downlight bodies 3 can still be stably powered under different spacing. The connecting component includes a telescopic electrical connecting wire 7 (to realize length adjustment) and a third concave connector 701 and a second convex connector 702 (as an adapter interface) at both ends. The third concave connector 701 is engaged with the first convex connector 303 on the downlight body 3, and the second convex connector 702 is engaged with the second concave connector 302 on the downlight body 3. Through standardized interface design, the universality and stability of the connecting component are guaranteed.

[0031] Working principle: Initial setup: The mounting rail 1 is pre-fixed to the target lighting area on the roof of the shopping mall via the top mounting support 101 and bolt connectors; the controller 5 and the interface base 4 are electrically connected via the connecting wire 6 to form the initial power supply circuit; the interface base 4 is mechanically fixed and electrically connected by snapping the plug into the first recessed connector 301 of the downlight body 3. Since two sets of interface bases 4 are pre-set in the mounting rail 1, two downlight bodies 3 with independent lighting functions are deployed in the initial state, and both are in a state of waiting to be activated.

[0032] Basic position adjustment: According to the initial lighting needs of the shopping mall, push the downlight body 3 horizontally along the lower cavity of the installation guide rail 1 until it moves to the target lighting position; during this process, the downlight body 3 drives the interface base 4 to slide synchronously, and the interface base 4 pulls the connecting wire 6 to follow, thus completing the pre-positioning of the downlight body 3.

[0033] When changes occur in the shelf layout or expansion of the promotional area in a supermarket setting, and the lighting power of the initial two downlight bodies 3 is insufficient to meet the local strong light requirements, it is necessary to increase the lighting intensity by adding a new downlight body 3. The operation process is as follows: slide the new downlight body 3 into the lower cavity through the flared openings 903 at both ends of the bottom of the mounting rail 1, ensuring that the downlight body 3 slides and adapts to the inner wall of the rail, and completes the physical installation.

[0034] If the newly added downlight body 3 needs to be close to the already deployed downlight body 3 (such as concentrated lighting directly above promotional items), the second concave connector 302 of the newly added downlight body 3 is engaged with the first convex connector 303 of the adjacent downlight body 3 to achieve mechanical splicing and electrical circuit conduction, so that the newly added downlight body 3 can be connected to the original power supply system and lit up synchronously.

[0035] If it is necessary to set up independent lighting units at different points within the installation guide rail 1 (such as supplemental lighting at the intervals between multiple sets of shelves), first slide the corresponding number of downlight bodies 3 into the guide rail and move them to the target points. Then, use the telescopic electrical connection cable 7 to achieve electrical connection between adjacent downlight bodies 3. The third concave connector 701 and the second convex connector 702 at both ends of the telescopic electrical connection cable 7 are respectively engaged with the first convex connector 303 and the second concave connector 302 of the adjacent downlight body 3. The telescopic structure is used to adapt to different spacing requirements and ensure stable power supply.

[0036] When the demand for supermarket lighting decreases (such as the end of promotional activities or the removal of shelves), excess downlight bodies 3 need to be removed to achieve energy saving. The operation steps are as follows: If the downlight body 3 to be removed is connected to the adjacent unit through the telescopic electrical connection cable 7, directly unplug the connectors at both ends of the telescopic electrical connection cable 7 to disconnect its electrical circuit with the surrounding downlight bodies 3, so as to avoid the risk of leakage during removal.

[0037] Push the downlight body 3 along the guide rail to the flared opening 903, remove the downlight body 3 from the flared opening 903, and the removal is complete; after removal, the position of the remaining downlight body 3 can be readjusted and locked to ensure that the lighting coverage matches the current scene requirements.

[0038] Example 2: Based on Example 1, as follows Figure 7 As shown, the bottom of the mounting rail 1 is provided with a pressure plate 801 for positioning. Each downlight body 3 is threaded with a screw 8 that has a locking function. When the downlight body 3 slides along the rail to the designated lighting position, the top of the screw 8 can be tightened to make it tightly abut against the pressure plate 801. The position of the downlight body 3 is locked by friction, preventing it from being displaced due to external forces (such as personnel collisions or airflow disturbances), and ensuring accurate lighting range.

[0039] like Figure 8 As shown, the H-shaped partition 2 is slidably connected to symmetrically distributed carriages 9. Their core function is to guide and organize the connecting wires 6, preventing them from becoming tangled or messy as they move with the interface base 4. When it is necessary to make the controller 5 electrically connected to the interface base 4, the movable end of the connecting wire 6 can first pass around the crossbar of the carriage 9 (forming a constraint guide), and then pass out from the outlet and connect to the interface base 4. Each carriage 9 is connected to the H-shaped partition 2 by symmetrically distributed springs 10, which are all wrapped around the adjacent carriage 9. The springs 10 can adaptively adjust the position of the carriage 9 through elastic deformation, always providing a stable tension force for the connecting wires 6, and preventing the connecting wires 6 from becoming loose or excessively pulled.

[0040] Rotary drums 901 are rotatably connected to the crossbars on the opposite sides of the carriage 9. Their function is to convert the sliding friction between the connecting wire 6 and the carriage 9 into rolling friction, which greatly reduces the wear of the connecting wire 6 and extends its service life. Each outlet has an arc surface 902 on its transverse section. The smooth curved surface design replaces the sharp edge, further reducing the friction damage between the connecting wire 6 and the edge of the outlet during movement, and ensuring the stability of power transmission.

[0041] Once the downlight body 3 is moved to the target position, the threaded screw 8 at its bottom is tightened so that the top of the screw 8 is tightly abutted against the pressure plate 801 at the bottom of the mounting rail 1. The friction force is used to achieve mechanical locking of the downlight body 3, preventing displacement caused by external forces such as personnel collisions or airflow disturbances, and ensuring accurate lighting range.

[0042] During the horizontal movement of the downlight body 3 and the interface base 4, the connecting wire 6 is pulled along with the interface base 4, causing the rotating cylinder 901 on the crossbar of the slide 9 to roll, converting sliding friction into rolling friction and reducing wire wear. At the same time, the connecting wire 6 pushes the slide 9 to slide along the H-shaped partition 2, causing the spring 10 to produce adaptive elastic deformation. The elastic feedback of the spring 10 maintains the constant tension of the connecting wire 6, preventing the wire from becoming loose and tangled or from being excessively pulled and broken, ensuring the continuous conduction of the power supply circuit, and preventing brightness fluctuations or intermittent power outages in the downlight body 3.

[0043] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
