[0002] Fresh food lighting is a type of lighting fixture specifically designed for illuminating fresh food areas. Its main purpose is to improve the spatial harmony of fresh food zones, optimize lighting, and make these zones brighter and more distinctive. However, existing fresh food lighting technologies generally use fixed assembly with a fixed illumination direction, as shown in CN202422005454.X. When the illumination direction needs to be adjusted, the fresh food light must be disassembled and then repositioned to achieve the angle adjustment. This process is not only cumbersome, but repeated disassembly and reassembly can also easily damage the fresh food light, making it difficult to meet the needs of different situations and limiting its applicability.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] See Figures 1 to 3 As shown, a fresh food lamp structure with an adjustable connector includes a lamp body 1, a heat sink 2 disposed inside the lamp body, and a light source plate 3 fixed to the bottom surface of the heat sink. The illumination surface of the lamp body is provided with a lampshade 4, and an adjustable connector 5 is provided between the lamp body and the heat sink. In this embodiment, the lamp body, heat sink, light source plate, and lampshade are all conventional structures of the prior art, and are simply applied, so they are not described in detail.

[0030] In this embodiment, the adjusting connector includes a support column 51 fixed to the top wall of the lamp cavity of the lamp body, a ball head support rod 52 threaded to the top of the radiator, and an electric telescopic rod 54 rotatably connected to the upper part of the inner wall of the lamp body via a pin 53. The electric telescopic rod is a conventional structure of the prior art, as shown in CN202420361058.8. During processing, a hemispherical cavity 6 is provided on the bottom surface of the support column, and an annular pressure cap 7 is threaded to the bottom of the support column. The diameter of the ball head of the ball head support rod matches the diameter of the hemispherical cavity, and the inner diameter of the annular pressure cap is smaller than the diameter of the ball head of the ball head support rod but larger than the diameter of the rod body of the ball head support rod. Therefore, the ball head support rod can rotate and adjust within the annular pressure cap.

[0031] During assembly, the ball-head support rod is rotatably mounted within the hemispherical cavity and limited by an annular cap. After being limited by the annular cap, there is a certain friction between the ball-head support rod and the hemispherical cavity. The magnitude of this friction can be adjusted by the tightness of the annular cap, which is common knowledge in the prior art. The annular cap is fitted onto the body of the ball-head support rod. For ease of connection, a support 9 is rotatably connected to the lower side wall of the radiator via a shaft 8. The electric telescopic rod is connected to the support, and the electric telescopic rod is connected to the inner wall of the lamp body via a pin. In practical applications, the shaft and pin are parallel to each other and are both horizontally positioned. For pin installation, a U-shaped mounting block is placed on the inner wall of the lamp body. The end of the electric telescopic rod is located within the U-shaped block and connected via the pin. This is standard technical knowledge. Due to the limiting effect of the U-shaped mounting block, the pin can only adjust in the tilt direction under its guidance, limiting the forward and backward movement of the electric telescopic rod and preventing large-scale swaying. In other words, the support can rotate in the tilt direction on the shaft, and the electric telescopic rod can also rotate in the tilt direction on the pin.

[0032] When the electric telescopic rod extends, the distance between the pin and the shaft changes, causing the electric telescopic rod to rotate upwards around the pin. Simultaneously, the support also rotates upwards around the shaft. This reduces the angle between the support and the radiator, while increasing the angle between the electric telescopic rod and the lower part of the lamp's inner wall. The top of the radiator adjusts its swing angle left and right around the ball joint support. Due to the constraints of the pin and mounting holes, and the shaft and mounting holes, the radiator does not exhibit significant forward or backward swaying. Furthermore, there is friction between the ball joint support and the inner wall of the hemispherical cavity. After adjustment, the length of the electric telescopic rod is limited by the drive structure within the rod, and the friction between the ball joint support and the hemispherical cavity limits the radiator's position. Therefore, without significant external force, the radiator will not exhibit large forward or backward swaying.

[0033] With the above structure, the ball joint can be rotated in the hemispherical cavity by extending and retracting the electric telescopic rod, so as to achieve angle adjustment. This ensures the effectiveness and stability of the adjustment, and allows the heat sink and light source plate to tilt at different angles to meet the illumination requirements in different directions. Furthermore, the swing range can be matched with the diameter of the lamp body.

[0034] In practical applications, magnets 10 are embedded in the ends of both the support and the electric telescopic rod; the electric telescopic rod and the support are positioned by magnetic attraction. The magnets are strong neodymium iron boron magnets, improving the ease of connection; furthermore, the diameters of the heat sink and the light source plate are smaller than the lamp cavity diameter; a screw hole is fixed to the top of the lamp body; a stud passes through the screw hole and is threaded to the top of the support column. With this structure, before installation, the heat sink and the support column are connected first, then the entire structure is placed inside the lamp body, and finally the support column is fixed with the stud, improving the convenience and effectiveness of installation.

[0035] In this embodiment, a connecting ring 11 is fixed to the bottom surface of the lamp body by screws. The connecting ring is a light-transmitting plastic structural component. Several L-shaped locking blocks 12 are integrally formed along the bottom edge of the connecting ring. The top surface of the lampshade is provided with a number of strip-shaped slots 13 equal to the number of L-shaped locking blocks. The L-shaped locking blocks are inserted into the strip-shaped slots and rotated to allow the lampshade to be detachably fixed to the bottom surface of the connecting ring. In practical applications, the bending directions of the several L-shaped locking blocks are in the same direction, so that when the lampshade is installed and rotated, each L-shaped locking block can be locked and positioned within the strip-shaped slot, improving the convenience and effectiveness of installation.

[0036] In this embodiment, a remote control circuit board 14 connected to the electric telescopic rod is fixed on the inner wall of the lamp body, and a plurality of heat dissipation holes 15 are provided on the lamp body. The remote control circuit board is a conventional structure of the prior art, simply applied for remote control operation. The heat dissipation holes are mainly used for heat dissipation to prevent heat from the radiator from accumulating inside the lamp body and to improve the service life of the lamp body.

[0037] This utility model has positive effects: The structure of this utility model is reasonably designed. An adjustable connector is provided between the lamp body and the heat sink. The adjustable connector includes a support column, a ball head support rod, and an electric telescopic rod. Together with the support on the lower side wall of the heat sink, it can not only quickly connect the heat sink and the lamp body, but also adjust the tilt angle of the heat sink through the electric telescopic rod. When lighting different areas, only the electric telescopic rod needs to be adjusted, which helps to reduce the difficulty of adjustment, improve the convenience and effectiveness of adjustment, and also facilitates disassembly, assembly and maintenance. It has strong applicability.

[0038] Furthermore, magnets are embedded in both the support and the end of the electric telescopic rod. When connected, the electric telescopic rod and the support are magnetically connected by the magnets, which improves the convenience and effectiveness of the connection.

[0039] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
