Description

Technical Field

[0001] This utility model relates to the field of lighting, and more specifically, to a lamp tube. Background Technology

[0002] As residents' living standards gradually improve, refrigerators have become one of the most frequently used appliances in households, fulfilling daily needs such as food preservation and snack storage. To allow users to quickly and clearly see the various items in the refrigerator compartment, most refrigerators on the market are equipped with dedicated lighting tubes in the refrigerator area, a design intended to improve ease of use. However, for common upright refrigerators, due to limitations in the installation position of the light tubes and the light propagation path, the emitted light is uneven, often failing to evenly cover the entire refrigerator compartment. This results in some areas being bright and transparent, while other corners are dark and blurry, creating a significant problem of uneven lighting and making it inconvenient for users to find food. Utility Model Content

Detailed Implementation

[0023] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0024] like Figures 1-5 The lamp tube shown includes: a mounting tube 20 with a lens 10, a support structure 40 disposed inside the mounting tube 20 for placing a lamp strip 30 and supporting the mounting tube 20 to prevent deformation, and a side cover 50 that cooperates with the end of the mounting tube 20; wherein the lens 10 includes a first light-emitting surface 11 and a second light-emitting surface 12 arranged at an angle.

[0025] In this embodiment, the lamp tube is designed with lenses 10 arranged at an angle, forming a first light-emitting surface 11 and a second light-emitting surface 12. This disperses the light to both sides, altering the light distribution and ensuring uniform light emission, thus improving the problem of uneven brightness inside the refrigerator. Simultaneously, this embodiment incorporates a support structure 40, reducing the overall size of the lamp tube while maintaining structural stability. Furthermore, the support structure 40 can also house the light strip 30, achieving a multi-functional effect.

[0026] The mounting pipe 20 described in this embodiment is a PC pipe.

[0027] In this embodiment, the lens 10 is pointed, and the first light-emitting surface 11 and the second light-emitting surface 12 are planar, curved, or bent surfaces. Specifically, in this embodiment, the first light-emitting surface 11 and the second light-emitting surface 12 are curved surfaces with bends, and the side of the lens 10 near the lamp bar 30 is a light-incident surface with multiple bent planes. In this embodiment, the light-incident surface is arranged axially symmetrically, and the center line of the lamp bar 30 is located on the axis of symmetry of the light-incident surface, so that the light emitted by the lamp bar 30 enters the lens 10 uniformly and then exits.

[0028] In this embodiment, the first light-emitting surface 11 and the second light-emitting surface 12 are symmetrically arranged, thereby making the light emission more uniform. Specifically, the included angle between the first light-emitting surface 11 and the second light-emitting surface 12 is an acute angle.

[0029] The support structure 40 described in this embodiment is an aluminum profile, but in other embodiments it can be other materials with support functions. The support structure 40 is a closed structure on all four sides, that is, it is a closed ring, a ring-like structure, or a frame structure. Specifically, the support structure 40 described in this embodiment is a frame structure that matches the inner cavity of the mounting tube 20, thereby preventing the mounting tube 20 from deforming.

[0030] The support structure 40 described in this embodiment is provided with a receiving groove 41 for placing the light strip 30. The receiving groove matches the outer contour of the light strip 30 and serves to limit the position of the light strip 30.

[0031] The inner wall of the mounting tube 20 described in this embodiment is further provided with a protruding rib 21 for positioning the support structure 40 and for tenon-and-mortise engagement with the side cover 50. Specifically, the protruding rib 21 extends into the interior of the mounting tube 20, thereby limiting or positioning the support structure 40 located inside; and the protruding rib 21 also serves as a connecting structure for tenon-and-mortise engagement with the side cover 50.

[0032] In this embodiment, there are two protruding ribs 21, which are respectively provided on two opposite side walls of the mounting tube 20. Specifically, in this embodiment, the two protruding ribs 21 are symmetrically arranged to simplify the manufacturing process.

[0033] The side cover 50 of this embodiment includes a mounting protrusion 51 that inserts into the inner cavity of the mounting tube 20, and a clamping groove 52 provided on the mounting protrusion 51 and tenon-ten ...

[0034] The groove 52 described in this embodiment has a trumpet-shaped cross-section, wherein the larger diameter end of the trumpet shape is the slot end. Therefore, when the side cover 50 is inserted into the mounting tube 20, the slot at the larger diameter end not only allows for smooth insertion but also provides guidance and limitation for the insertion assembly.

[0035] Furthermore, in this embodiment, the line connecting the end of the clamping groove 52 and the opening end is inclined at an angle, that is, the clamping groove 52 as a whole presents an upward or downward inclined angle. Thus, when the protruding ridge 21 and the clamping groove 52 are engaged, there is a certain angle between the straight protruding ridge 21 and the inclined clamping groove 52, that is, there is a mutual squeezing force between the two, making the engagement between the protruding ridge 21 and the clamping groove 52 more reliable and firm.

[0036] In this embodiment, the outer wall of the mounting protrusion 51 is further provided with a hook 53 that elastically engages with the mounting tube 20. The hook 53 is an elastic element with an elastic modulus. Specifically, the hook 53 is located at the bottom of the outer wall of the mounting protrusion 51, thereby elastically engaging with the bottom of the inner wall of the mounting tube 20. After assembly, the hook 53 is compressed, creating a continuous outward tension that secures the mounting protrusion 51 to the mounting tube 20, further preventing the side cover 50 from easily loosening. Compared to traditional lamp tubes, where the side cover needs to be fixed with screws or tape after being glued, which is inconvenient for production, the side cover 50 of this embodiment, through the above design, engages with the mounting tube 20, saving assembly time and improving production efficiency.

[0037] The side cover 50 of this embodiment also includes an extension cover 54 that mates with the lens 10. The extension cover 54 covers the top of the portion of the lens 10 near the side cover 50, and the outer edges of both sides of the extension cover 54 abut against the top edge of the mounting tube 20. The extension cover 54 is designed to match the shape of the lens 10. Combined with the matching method with the mounting tube 20, it can play a guiding, limiting, and positioning role when the side cover 50 is installed; on the other hand, it can protect the lens 10, preventing it from being touched or damaged during lamp assembly.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
