Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and in particular to a splicing LED floodlight. Background Technology
[0002] LED floodlights, as large-area directional lighting devices, are widely used in outdoor locations such as building facade lighting, stadiums, and plazas. Traditional LED floodlights typically employ a single-unit structure, with tilt angle adjustment achieved through a rotating bracket. With the increasing demand for modular lighting, modular floodlights, due to their scalability, installation flexibility, and ability to provide uniform illumination, are gradually becoming the mainstream choice for scenarios such as road lighting and large billboards.
[0003] Currently, splicing floodlights consist of multiple lamp bodies. After the lamp bodies are installed, when angle adjustments are needed, each lamp body must be adjusted independently. This results in angular deviations between adjacent lamp bodies, causing bright and dark stripes at the splicing points due to angular deviations, which affects the lighting effect. Furthermore, adjusting each lamp body individually is cumbersome, time-consuming, and labor-intensive. Summary of the Invention
[0004] 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 LED floodlight that can synchronously adjust the lamp body angle, is simple to operate, and saves time and effort.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A modular LED floodlight includes several identical lamp body units and at least one fixed bracket. The two ends of the fixed bracket are connected to the lamp body units, and the fixed bracket is provided with mounting holes.
[0007] The lamp body unit includes a lamp housing, which has a light source mounting part for mounting a light source and a lamp shade mounting part for mounting a lamp shade. Both the light source mounting part and the lamp shade mounting part are square structures, and the size of the lamp shade mounting part is larger than that of the light source mounting part. Connecting pins are fixed on all four sides of the light source mounting part. The fixing bracket is U-shaped and has pin holes at both ends that allow the connecting pins to pass through. The outer side of the connecting pin is provided with external threads, and a clamping nut for pressing and fixing the fixing bracket is threaded onto the connecting pin. The lamp shade mounting parts of adjacent lamp body units are fitted together, and adjacent lamp body units are connected by a connecting structure.
[0008] In this way, the required number of individual lamp bodies and the number of fixed brackets are selected according to the lighting needs. First, the fixed brackets are connected to the lamp housings of the individual lamp bodies, and then adjacent individual lamp bodies are spliced together.
[0009] When connecting the fixed bracket to the lamp body, the fixed bracket is a metal profile, usually made of bent steel plate, which has the ability to deform. Apply force to both ends of the fixed bracket outward and move it to the outside of the lamp housing. Loosen the fixed bracket, and the fixed bracket will return to its original position. The connecting pin passes through the pin hole of the fixed bracket. Tighten the clamping nut on the outside of the connecting pin and tighten the fixed bracket to complete the connection between the fixed bracket and the lamp body. The outer end of the connecting pin is located on the outside of the clamping nut.
[0010] When connecting adjacent lamp units, a connecting structure is used to form a whole. The lampshade mounting parts of adjacent lamp units are fitted together, maximizing the contact area and improving the overall integrity and stability of the assembled LED floodlight. To adjust the angle, loosen the clamping nut; after the lamp units are assembled, they can rotate relative to the fixed bracket. Once the desired angle is reached, tighten the clamping nut to fix the current angle for easy use.
[0011] Preferably, a wear-resistant sleeve is fixed to the end of the connecting pin near the light source mounting part, and the wear-resistant sleeve abuts against the fixed bracket.
[0012] Preferably, each of the four sides of the lampshade mounting part has two stepped insertion holes, and when the lampshade mounting parts of adjacent lamp bodies are fitted together, insert blocks are inserted into the two stepped insertion holes.
[0013] Preferably, the connecting structure includes a connecting shaft, on which two pressure rings are slidably sleeved. Limiting ribs are provided circumferentially at both ends of the connecting shaft. Locking nuts capable of connecting with the external threads of the connecting pin are fixedly installed on the outer side of the pressure rings. The connecting pin has a socket that allows the end to be inserted. A limiting slot is provided circumferentially in the socket to engage with the limiting ribs.
[0014] Preferably, both the compression nut and the locking nut are provided with a drive ring on their outer sides, and the drive ring is provided with anti-slip slots at intervals around its circumference.
[0015] In summary, this modular LED floodlight has the advantages of synchronously adjusting the lamp body angle, simple operation, and saving time and effort. Attached Figure Description

[0020] 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.
[0021] like Figure 1-4 As shown, a splicing LED floodlight includes several identical lamp body units and at least one fixed bracket 1. The two ends of the fixed bracket are connected to the lamp body units, and the fixed bracket is provided with mounting holes 2.
[0022] The lamp body unit includes a lamp housing, which has a light source mounting part 3 for mounting a light source and a lamp shade mounting part 4 for mounting a lamp shade. Both the light source mounting part and the lamp shade mounting part are square structures, and the size of the lamp shade mounting part is larger than that of the light source mounting part. Connecting pins 5 are fixed on all four sides of the light source mounting part. The fixing bracket is U-shaped and has pin holes 6 at both ends that allow the connecting pins to pass through. The outer side of the connecting pin is provided with external threads, and a clamping nut 7 for pressing and fixing the fixing bracket is threaded onto the connecting pin. The lamp shade mounting parts of adjacent lamp body units are fitted together, and adjacent lamp body units are connected by a connecting structure.
[0023] In this way, the required number of individual lamp holders and mounting brackets are selected according to the lighting needs. First, the mounting brackets are connected to the lamp housings of the individual lamp holders, and then adjacent lamp holders are spliced together. The individual lamp holders have an existing structure, with a light source mounting plate and a lampshade installed inside their housings. The light source mounting plate is connected to a driver power supply.
[0024] When connecting the fixed bracket to the lamp body, the fixed bracket is a metal profile, usually made of bent steel plate, which has the ability to deform. Apply force to both ends of the fixed bracket outward and move it to the outside of the lamp housing. Loosen the fixed bracket, and the fixed bracket will return to its original position. The connecting pin passes through the pin hole of the fixed bracket. Tighten the clamping nut on the outside of the connecting pin and tighten the fixed bracket to complete the connection between the fixed bracket and the lamp body. The outer end of the connecting pin is located on the outside of the clamping nut.
[0025] When connecting adjacent lamp units, a connecting structure is used to form a whole. The lampshade mounting parts of adjacent lamp units are fitted together, maximizing the contact area and improving the overall integrity and stability of the assembled LED floodlight. To adjust the angle, loosen the clamping nut; after the lamp units are assembled, they can rotate relative to the fixed bracket. Once the desired angle is reached, tighten the clamping nut to fix the current angle for easy use.
[0026] In practice, a wear-resistant sleeve 8 is fixed to the end of the connecting pin near the light source mounting part, and the wear-resistant sleeve abuts against the fixed bracket. The wear-resistant sleeve, in conjunction with the clamping nut, presses the fixed bracket firmly onto the lamp body unit. When the angle needs to be adjusted, the clamping nut is loosened, allowing the fixed bracket and the lamp body unit to rotate relative to each other. After the angle is adjusted to the desired position, the clamping nut is tightened to fix the position of the fixed bracket relative to the lamp body unit.
[0027] In implementation, two stepped insertion holes 9 are provided on each of the four sides of the lampshade mounting part. When the lampshade mounting parts of adjacent lamp bodies are fitted together, insertion blocks 10 are inserted into the two stepped insertion holes. By setting the insertion blocks, adjacent lamp bodies can be connected not only by the connecting structure but also by the insertion blocks, making the connection between adjacent lamp bodies more stable and allowing for more synchronized angle adjustments.
[0028] In implementation, the connection structure includes a connecting shaft 11, on which two pressure rings 12 are slidably sleeved. Limiting ribs 13 are circumferentially protruding at both ends of the connecting shaft. Locking nuts 14 that can be connected to the external threads of the connecting pin are fixedly installed on the outer side of the pressure rings. The connecting pin has a socket 15 that allows the end to be inserted. A limiting slot is provided circumferentially in the socket to engage with the limiting ribs.
[0029] In this way, when connecting two lamp bodies, the two ends of the connecting shaft are inserted into the sockets of the connecting pins of the two lamp bodies respectively, the limiting ribs are inserted into the limiting slots, and then the two pressure rings are moved and fixedly connected to the two connecting pins by the two locking nuts respectively, so that the pressure rings and the ends of the connecting pins abut and press together to complete the connection.
[0030] In practice, both the clamping nut and the locking nut are provided with a drive ring 16 on their outer sides, and the drive ring is provided with anti-slip grooves at intervals around its circumference. This facilitates the rotation of the clamping nut and the locking nut.
[0031] Connecting pins are fixed on all four sides of the light source mounting section, enabling multi-directional splicing, such as in a straight line, a square shape, or a matrix shape. The number of individual lamp bodies can be selected according to actual needs. The number of fixing brackets is half or more than half the number of individual lamp bodies to improve installation stability.
[0032] By using a connecting structure to connect adjacent lamp units, rotation between them is avoided, and when adjusting the angle, several lamp units can adjust their angles synchronously.
[0033] 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.
