Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a splicing linear lamp. Background Technology

[0002] With the increasing demands for aesthetics, functionality, and flexibility in modern architectural lighting design, linear luminaires, due to their simple shape, uniform luminous efficacy, and customizability, are widely used in commercial spaces, offices, home decoration, and outdoor landscaping. Traditional linear lights often employ a monolithic structure, where the lamp body is formed from a single long strip profile (such as an aluminum alloy profile), integrating the light source module, driver, and optical components. While this design satisfies structural strength and sealing requirements to some extent, the following technical challenges have gradually emerged in practical applications:

[0003] 1. High transportation and warehousing costs: The length of integrated linear lights is usually customized according to project requirements (e.g., 2 to 6 meters). Extra-long profiles require a lot of space during transportation, leading to a significant increase in logistics costs. In addition, long profiles have strict requirements for warehousing conditions and are prone to irreversible deformation due to compression or bending, affecting the yield of finished products;

[0004] 2. Limited installation flexibility: In complex construction scenarios (such as confined spaces, irregularly shaped ceilings, or curved walls), long, integral light fixtures are difficult to adapt to flexible adjustments in the site layout. Precise measurements and pre-embedded fixing structures are required during installation, resulting in a low tolerance for construction errors. Furthermore, any length or positional deviations lead to high rework costs.

[0005] To address the problems of linear lights with an integral structure, spliced ​​linear lights have emerged. These lights consist of multiple profiles with adjacent profiles fixedly connected on both sides by connecting plates. During use, light leakage is very likely to occur at the joints of the profiles, and the joints are prone to failure and deformation during hoisting, affecting normal use. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a splicing linear lamp that is stable in connection, simple in operation, and convenient in transportation.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A modular linear lamp includes at least two lamp housing units, a light-transmitting cover equal in number to the number of lamp housing units, and two end caps. The ends of adjacent lamp housing units facing each other are connected by a connecting structure. The end caps have wire holes and are fixedly connected to the lamp housing units.

[0009] The lamp housing unit includes an outer shell and an inner shell. The outer shell is U-shaped with one end open. The inner shell is spaced inside the outer shell and both ends of the inner shell are fixedly connected to the outer shell through connecting plates. A slot is formed between the inner shell and the outer shell. The inner shell has a placement groove for placing LED light sources. The open end of the outer shell has a protruding edge. A sliding groove is formed between the protruding edge and the connecting plate to allow the light-transmitting cover to slide in.

[0010] The connection structure includes two connecting frames, which are L-shaped. The two ends of the connecting frames are inserted into the slots of two adjacent lamp housing units. Nuts are fixedly installed on the connecting frames opposite to the two housings. The inner holes of the connecting frames and housings opposite to the nuts are provided with clearance holes. The connecting frames and housings are fixedly connected by bolts.

[0011] In this way, by setting up multiple lamp housing units, the original single profile is divided into several units, which facilitates transportation. When connecting adjacent lamp housing units, one end of the two connecting brackets is inserted into the slot of one lamp housing unit, and bolts are used to connect it to the nut after passing through the clearance hole. Then, the other end of the two connecting brackets is inserted into the slot of the adjacent lamp housing unit, and bolts are used to connect it to the nut after passing through the clearance hole, thus completing the connection of the two adjacent lamp housing units. Next, the LED light source is installed in the placement slot of the inner shell, and the LED light source wire is connected to the driver power supply after passing through the wire hole of the plug. The light-transmitting cover is slid into the slide groove of the lamp housing unit. After the light-transmitting cover is installed, the plug is fixed to both ends of the lamp housing unit to complete the assembly.

[0012] Preferably, a reinforcing rib is fixedly installed between the outer shell and the inner shell, and the reinforcing rib is positioned directly opposite the middle of the outer shell and the inner shell.

[0013] Preferably, the sidewalls and bottomwalls of the outer casing are provided with protruding ribs, and the connecting frame is provided with grooves that slide with the protruding ribs.

[0014] Preferably, the plug is fixedly installed with two rubber blocks, and the rubber blocks are interference-fitted with both sides of the slot.

[0015] Preferably, the lamp housing is formed by integrally molding a profile.

[0016] In summary, this modular linear light has the advantages of stable connection, simple operation, and convenient transportation. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0022] like Figure 1-4 As shown, a splicing linear lamp includes at least two lamp housing units 1, a light-transmitting cover 2 with the same number of lamp housing units, and two plugs 3. The ends of adjacent lamp housing units facing each other are connected by a connecting structure. The plugs are provided with wire holes and are fixedly connected to the lamp housing units.

[0023] The lamp housing unit includes an outer shell 4 and an inner shell 5. The outer shell is U-shaped with one end open. The inner shell is spaced inside the outer shell and both ends of the inner shell are fixedly connected to the outer shell through connecting plates 6. A slot 7 is formed between the inner shell and the outer shell. The inner shell has a placement groove for placing LED light sources. The open end of the outer shell has a protruding edge 8. A sliding groove 9 is formed between the protruding edge and the connecting plate to allow the light-transmitting cover to slide in.

[0024] The connection structure includes two connecting frames 10, which are L-shaped. The two ends of the connecting frames are inserted into the slots of two adjacent lamp housing units. Nuts 11 are fixedly installed on the connecting frames opposite to the two housings. The inner holes of the connecting frames and housings opposite to the nuts are provided with clearance holes 12. The connecting frames and housings are fixedly connected by bolts.

[0025] In this way, by setting up multiple lamp housing units, the original single profile is divided into several units, which facilitates transportation. When connecting adjacent lamp housing units, one end of the two connecting brackets is inserted into the slot of one lamp housing unit, and bolts are used to connect it to the nut after passing through the clearance hole. Then, the other end of the two connecting brackets is inserted into the slot of the adjacent lamp housing unit, and bolts are used to connect it to the nut after passing through the clearance hole, thus completing the connection of the two adjacent lamp housing units. Next, the LED light source is installed in the placement slot of the inner shell, and the LED light source wire is connected to the driver power supply after passing through the wire hole of the plug. The light-transmitting cover is slid into the slide groove of the lamp housing unit. After the light-transmitting cover is installed, the plug is fixed to both ends of the lamp housing unit to complete the assembly.

[0026] Firstly, the lamp housing unit, through the design of the outer and inner shells, forms a slot. The connecting bracket, inserted into the slot and in an L-shape, blocks light from both sides of the lamp housing unit, preventing light leakage. Secondly, the L-shaped connecting bracket provides support during the overall hoisting process after the lamp housing unit is assembled, preventing bending and failure, and extending its service life. The LED light source is a PCB board with LED chips mounted on it; this is an existing structure that can be directly glued to the inner shell, and light is transmitted through a light-transmitting plate.

[0027] In practice, a reinforcing rib 13 is fixedly installed between the outer shell and the inner shell, with the reinforcing rib positioned directly opposite the center of the outer shell and the inner shell. This makes the connection between the outer shell and the inner shell tighter and more reliable.

[0028] In implementation, the side walls and bottom walls of the outer casing are provided with protruding ribs 14, and the connecting frame is provided with grooves 15 that slide with the protruding ribs. This makes the connection between the connecting frame and the outer casing more stable and reliable.

[0029] In practice, the plug is fixedly installed with two rubber blocks 16, which are interference-fitted with both sides of the slot. The rubber blocks achieve sealing and facilitate assembly.

[0030] In practice, the lamp housing is formed as a single piece using a profile. This facilitates manufacturing; it is typically made from aluminum profiles through direct molding.

[0031] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
