Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to a lighting fixture and electronic device. Background Technology
[0002] Lighting fixtures, as devices that provide illumination, help users observe in low-light environments. The requirements for lighting fixtures vary greatly depending on the environment in which they are used. For example, lighting fixtures used in environments such as refrigerators and bathrooms need to be waterproof to ensure that they can work normally in humid environments.
[0003] In the process of developing this utility model, the inventors discovered that: Currently, lamps include a lamp tube, a light-emitting component, and an end cap. The lamp tube has a receiving cavity and a port connected to the receiving cavity. When assembling the lamp, the light-emitting component needs to be placed inside the receiving cavity through the port, and then the port is sealed with the end cap to form a closed space inside the lamp tube. However, in lamps with this structure, there is a gap between the inner wall of the end cap and the port, allowing external moisture to enter the receiving cavity through this gap, affecting the operation of the light-emitting component. When lamps need to operate in humid environments such as refrigerators, ultrasonic welding is usually used to weld the gaps in the lamp to ensure a complete seal, preventing moisture from entering. However, ultrasonic welding makes lamps used in humid environments like refrigerators too expensive, affecting the market competitiveness of refrigerators and other products that use lamps. Utility Model Content

[0030] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.
[0031] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0032] Please see Figures 1 to 5 The lamp 1000 includes a lamp tube 1, a sealing cover 2, and a light-emitting component 3. The lamp tube 1 is provided with a receiving cavity 11 and a port 12, and the port 12 is connected to the receiving cavity 11. The sealing cover 2 is provided at the port 12 so that the receiving cavity 11 forms a closed space to prevent external rainwater from entering the receiving cavity 11 and affecting the normal operation of the components housed in the receiving cavity 11. The light-emitting component 3 is housed in the closed space and can emit light to illuminate the area where the lamp 1000 is located.
[0033] Understandably, the shape of the lamp tube 1 includes, but is not limited to, any shape that can be assembled into electronic devices, such as a round tube or a square tube.
[0034] Understandably, in order to ensure that the light emitted by the light-emitting component 3 can smoothly illuminate the external environment, the material of the lamp tube 1 should be selected as a light-transmitting material, including but not limited to: glass, plastic, etc. For example, in this embodiment, the lamp tube 1 is preferably plastic. Furthermore, in order to ensure the waterproof performance of the lamp tube 1 and to reduce the processing steps and reduce the processing difficulty, the lamp tube 1 in this embodiment is integrally molded, specifically, by injection molding.
[0035] It should be noted that the sealing cap 2 can be used solely for sealing; or it can serve a decorative function while simultaneously providing a seal. For example, when the sealing cap 2 is used solely for sealing, it is completely housed within the receiving cavity 11. An end cap 4 is then added to the lamp 1000 to cover and decorate the port 12, enhancing the aesthetics of the lamp 1000. The separate arrangement of the end cap 4 and the sealing cap 2 allows companies to customize them according to their specific needs. When waterproofing is not required, the end cap 4 alone is sufficient to cover the port 12; when waterproofing is required, both the end cap 4 and the sealing cap 2 are assembled together. When the sealing cap 2 serves both sealing and decorative functions, a portion of the sealing cap 2 extends into the receiving cavity 11, while the other portion covers the port 12. To improve aesthetics, the cross-sectional area of the other portion of the sealing cap 2 is larger than that of the port 12 to ensure complete coverage of the port 12.
[0036] For example, in this embodiment, please refer to Figure 1 The luminaire 1000 includes an end cap 4, which is disposed on the port 12 and is located on the side of the sealing cover 2 away from the enclosed space.
[0037] Furthermore, to ensure the waterproof performance of the sealing cap 2, the sealing cap 2 is interference-fitted with the inner wall of the receiving cavity 11.
[0038] It is understood that the material of the sealing cap 2 should have the ability to undergo elastic deformation under external force, specifically including but not limited to: silicone, rubber, etc. For example, in this embodiment, the material of the sealing cap 2 is preferably rubber.
[0039] For information regarding the sealing cap 2 mentioned above, please refer to [link / reference]. Figure 2 The sealing cover 2 includes a main body 21 and a deformable part 22. The main body 21 ensures the structural strength of the sealing cover 2. The deformable part 22 is arranged around the periphery of the main body 21 and abuts against the inner wall of the receiving cavity 11 to seal the gap between the sealing cover 2 and the inner wall of the receiving cavity 11. The deformable part 22 can undergo elastic deformation so that the deformable part 22 fully abuts against the inner wall of the receiving cavity 11 and fills the gap between the main body 21 and the inner wall of the receiving cavity 11, thus ensuring the waterproofness of the lamp 1000.
[0040] Understandably, the shape of the sealing cap 2 needs to be compatible with the lamp tube 1 to ensure the waterproofness of the lamp 1000.
[0041] Furthermore, there are multiple deformable parts 22, and multiple deformable parts 22 are spaced apart along the axial direction of the main body 21. An adhesive filling groove 23 is formed between any two adjacent deformable parts 22. The adhesive filling groove 23 is used to fill the sealing cover 2 into the receiving cavity 11 when it is placed in the receiving cavity 11, so as to further improve the sealing performance of the sealing cover 2 to the lamp tube 1 and improve the waterproof performance of the lamp 1000.
[0042] Understandably, in order to facilitate the injection of sealant, except for the deformable portion 22 at the end of the main body 21 near the receiving cavity 11, all other deformable portions 22 are provided with clearance openings (not shown in the figure) so that the glue-filling grooves 23 can communicate with each other, facilitating the glue-filling operation; or except for the deformable portions 22 at both ends of the axial direction of the main body 21, all other deformable portions 22 are provided with clearance openings so that the glue-filling grooves 23 can communicate with each other, and the side wall of the lamp tube 1 is provided with a glue-filling port, which communicates with the glue-filling groove 23.
[0043] It should be noted that the connection method between the sealing cover 2 and the lamp tube 1 includes, but is not limited to, any combination of one or more of the following: interference fit, snap-fit, screw connection, etc.
[0044] For example, please refer to Figure 2 In this embodiment, in addition to the interference fit with the lamp tube 1, the sealing cover 2 also adopts a snap-fit connection method, which further improves the stability of the connection between the sealing cover 2 and the lamp tube 1 and enhances the connection strength between the sealing cover 2 and the lamp tube 1.
[0045] Specifically, the sealing cover 2 includes a first snap-fit portion 24, which is fixed to the periphery of the main body 21 and located on the side of the deformable portion 22 away from the enclosed space. The lamp tube 1 is provided with a first snap-fit through hole 13, which communicates with the receiving cavity 11. At least a portion of the first snap-fit portion 24 is inserted into the first snap-fit through hole 13. Through the cooperation of the first snap-fit portion 24 and the first snap-fit through hole 13, the sealing cover 2 is connected to the lamp tube 1. This structure also limits the sealing cover 2, preventing the sealing cover 2 from extending too far into the receiving cavity 11 and compressing the volume of the enclosed space, thus affecting the assembly of the light-emitting component 3.
[0046] Understandably, the number of first latching portions 13 is a positive integer greater than or equal to one. In this embodiment, there are two first latching portions 13, located on both sides of the main body 21. Correspondingly, there are also two first latching through holes 13.
[0047] It should be noted that the method by which the end cap 4 is disposed on the port 12 includes, but is not limited to, snap-fit, screw-fit, etc. For an example, please refer to [link to example]. Figure 2 In this embodiment, the end cap 4 is snapped onto the lamp tube 1 to cover the port 12.
[0048] Specifically, the lamp tube 1 is also provided with a second snap-fit hole 14, which communicates with the receiving cavity 11; the end cap 4 extends a second snap-fit portion 41 towards the receiving cavity 11, and at least a portion of the second snap-fit portion 41 is inserted into the second snap-fit hole 14. Through the cooperation of the second snap-fit portion 41 and the second snap-fit hole 14, the end cap 4 and the lamp tube 1 are snap-fitted together, and the end cap 4 is also limited to prevent it from extending excessively into the receiving cavity 11.
[0049] Understandably, the number of second latching portions 41 is a positive integer greater than or equal to one. In this embodiment, there are two second latching portions 41, located on both sides of the end cap 4. Correspondingly, there are also two second latching through holes 14.
[0050] It is understood that the light-emitting component 3 housed within the receiving cavity 11 requires power to emit light. The power supply methods for the light-emitting component 3 include, but are not limited to, direct connection to an external power source, wireless power supply, and a built-in battery. For example, in this embodiment, please refer to... Figure 1 and Figure 2 The light-emitting component 3 of this lamp 1000 is directly connected to an external power source.
[0051] Specifically, the lamp 1000 includes a connecting wire 5; the end cap 4 is provided with a through hole 42, which is used to allow one end of the connecting wire 5 to extend and connect to an external power source; the sealing cap 2 is provided with a wire-passing hole 25, which communicates with the receiving cavity 11, and the other end of the connecting wire 5 passes through the wire-passing hole 25 and is connected to the light-emitting component 3.
[0052] It should be noted that, in order to ensure the waterproofness of the sealing cap 2, the inner wall of the wire hole 25 is interference-fitted with the connecting wire 5. The rubber sealing cap 2 can deform elastically, so that the inner wall of the wire hole 25 completely covers the connecting wire 5.
[0053] Understandably, the way the 1000 lamp is connected to an external power source includes, but is not limited to: direct connection with a connecting wire, clamping with a flexible conductive element, and connection between a plug and a socket.
[0054] For example, please refer to the following: Figure 4 and Figure 5 In this embodiment, in order to facilitate the application of the lamp 1000 to the refrigerator and simplify the steps of assembling the lamp 1000 on the refrigerator, the elastic conductive member 6 is used for contact.
[0055] Specifically, the lamp 1000 also includes an elastic conductive element 6; the end cap 4 is provided with a receiving groove 43, and a through hole 42 is located at the bottom of the receiving groove 43. The elastic conductive element 6 is received in the receiving groove 43, and one end of the conductive element extends out from the through hole 42 and is connected to the connecting wire 5. Under normal conditions, the elastic conductive element 6 is in a naturally extended state, that is, a portion of the elastic conductive element 6 extends out of the receiving groove 43; when the elastic conductive element 6 is assembled on the refrigerator, the elastic conductive element 6 is in a compressed state, that is, the length of the elastic conductive element 6 extending out of the receiving groove 43 is shortened. The elastic conductive element 6 generates a contacting force on the bottom of the receiving groove 43 and on the structure of the refrigerator (such as the conductive sheet in the slot of the lamp 1000) that abuts against the elastic conductive element 6. While transmitting electrical energy, it also ensures the stability of the connection between the lamp 1000 and the refrigerator.
[0056] Understandably, the elastic conductive component 6 includes, but is not limited to, a spring or a sheet.
[0057] The number of sealing caps 2 and ports 12 mentioned above are both two. The two ports 12 are located at both ends of the receiving cavity 11. One sealing cap 2 extends into the receiving cavity 11 from one port 12 and covers one port 12. The other sealing cap 2 extends into the receiving cavity 11 from the other port 12 and covers the other port 12.
[0058] Furthermore, when the sealing cap 2 is only used for sealing, there are also two end caps 4, and one sealing cap 2 is housed in the receiving cavity 11, and one end cap 4 covers one port 12; the other sealing cap 2 is housed in the receiving cavity 11, and the other end cap 4 covers the other port 12.
[0059] For the light-emitting component 3 mentioned above, please refer to... Figure 1 The light-emitting component 3 includes a bracket 31 and a lamp plate 32. The lamp plate 32 is disposed on the bracket 31. The lamp plate 32 is connected to an external power source through the aforementioned connecting line 5, or the lamp plate 32 is connected to an external power source through the aforementioned connecting line 5 and the elastic conductive member 6. The bracket 31 is fixed to the inner wall of the receiving cavity 11.
[0060] Understandably, the methods by which the bracket 31 is fixed to the receiving cavity 11 include, but are not limited to: adhesive bonding, snap-fitting, interference fit between the bracket 31 and the inner wall of the receiving cavity 11, etc.
[0061] It is understood that the methods by which the lamp panel 32 is fixed to the bracket 31 include, but are not limited to, adhesive bonding, snap-fit bonding, screw bonding, etc. For example, in this embodiment, the lamp panel 32 is fixed to the bracket 31 by thermally conductive adhesive. While fixing the lamp panel 32, the thermally conductive adhesive also uses its thermal conductivity to transfer the heat generated by the lamp panel 32 during operation to the bracket 31 in a timely manner, ensuring the stability of the lamp panel 32 during operation.
[0062] In this embodiment, the lamp 1000 includes: a lamp tube 1, a sealing cover 2, and a light-emitting component 3. The lamp tube 1 is provided with a receiving cavity 11 and a port 12, with the port 12 communicating with the receiving cavity 11. The sealing cover 2 is disposed at the port 12, so that the receiving cavity 11 forms a closed space. The light-emitting component 3 is housed in the closed space. By sealing the port 12 with the sealing cover 2, the receiving cavity 11 is sealed, preventing external moisture from entering the receiving cavity 11 through the port 12 and causing a short circuit in the light-emitting component 3 housed in the receiving cavity 11. Compared with the prior art method of completely sealing the port 12 by laser welding, the sealing cover 2 has a simple structure and low processing cost, which greatly reduces the processing cost of the lamp 1000. Furthermore, the sealing cover 2 and the lamp tube 1 form a detachable structure, which facilitates the disassembly and maintenance of the lamp 1000. When the lamp 1000 malfunctions, it can be disassembled and repaired, reducing the operating cost of the lamp 1000.
[0063] This utility model also provides an electronic device embodiment, including the above-mentioned lamp 1000. For the specific structure and function of the lamp 1000, please refer to the above embodiment, which will not be repeated here.
[0064] It should be noted that while the preferred embodiments of this utility model are provided in the specification and accompanying drawings, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this utility model; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Furthermore, the above-described technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification. Moreover, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
