Inflatable stick lamp

Abstract

This invention provides an inflatable lamp, comprising a lamp body, a light source, and a reinforcing film. In this inflatable lamp, the reinforcing film is a flexible component, its edges fixed to the inner wall of the lamp body, forming a localized stress buffer structure. Furthermore, a first transition layer provides buffer protection between the reinforcing film and the light source. During inflation, the stress generated by the lamp body's expansion is dispersed throughout the entire inner wall of the lamp body via the reinforcing film, preventing stress concentration around the light source due to rigidity differences. The first transition layer provides protection on the surface of the light source, preventing localized tearing or damage to the lamp body. Moreover, when the lamp body deflates and curls, the reinforcing film undergoes elastic deformation to absorb external pressure and disperses pressure during curling, preventing damage to the light source due to excessive compression. Additionally, the perforations in the first transition layer generate a radial clamping force on the light-emitting part, preventing displacement during inflation and curling, thus avoiding misalignment of the light source, ensuring the effective use of the inflatable lamp, and extending its service life.

Description

Technical Field

[0001] This utility model relates to the field of light-emitting device technology, and in particular to an inflatable rod lamp. Background Technology

[0002] Inflatable stick lights, as a portable lighting tool, have been widely used in various scenarios in recent years. They mainly consist of a stick-shaped air bladder made of flexible material and a lighting component housed inside. Their lightweight and deformable characteristics, combined with their lighting function and portability, make them uniquely advantageous in outdoor camping, nighttime activities, and emergency lighting scenarios.

[0003] When in use, the inflatable light stick can be inflated by filling the air bladder with gas through the inflation valve, causing the bladder to expand and maintain its stick shape. Activating the lighting component then provides illumination. When not in use, the inflatable light stick can be rolled up into a compact roll for storage by releasing the gas through the deflation valve. This rolling storage method significantly reduces the product's size, saves storage space, and makes it convenient for users to carry or store in a centralized location.

[0004] However, when inflatable lamps are rolled up for storage, uneven force, excessively small rolling radius, or excessive force can easily cause the internal lighting components to shift or be damaged by pressure, affecting the normal use of the inflatable lamp. Utility Model Content

[0019] The inflatable light also includes a control handle, which contains a power supply module and a control module; the docking part is disposed on the end face of the control handle and is electrically connected to the power supply module and the control module.

[0020] The control handle is detachably connected to the lamp body, so that the electrical connection terminal is connected to the docking part to form an electrical connection, and the power supply module and the control module can form an electrical connection with the light source.

[0021] In some embodiments of this application, the mating portion includes a slot, and the electrical connection terminal is inserted and fixed in the slot of the mating portion to form an electrical connection; or, the mating portion includes a contact, and the electrical connection terminal abuts against the contact of the mating portion to form an electrical connection.

[0036] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0037] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and 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. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] like Figure 1 , Figure 2 as well as Figure 3As shown, one embodiment of this application provides an inflatable rod lamp 100, which includes a lamp body 10, a light source 20, a reinforcing film 30, and a first transition layer 40.

[0040] The lamp body 10 has an internal installation space and can expand when inflated. A light source 20 is disposed within the installation space, and the light emitted by the light source 20 can pass through the lamp body 10 and be projected into the external environment. The light source 20 may include a lamp panel 21 and multiple light-emitting parts 22, which are spaced apart on the surface of the lamp panel 21. The surface of the lamp panel 21 with the light-emitting parts 22 is the light-emitting surface 201, and the surface of the lamp panel 21 facing away from the light-emitting parts 22 is the backlight surface 202.

[0041] The reinforcing film 30 is a flexible and transparent component. It is disposed in the installation space and attached to the light-emitting surface 201 of the light source component 20. The edge of the reinforcing film 30 is fixedly connected to the inner wall of the lamp body 10. A first transition layer 40 is disposed between the reinforcing film 30 and the light source component 20. The first transition layer 40 has multiple through holes 401 arranged and connected through each other. Multiple light-emitting parts 22 are correspondingly inserted into the multiple through holes 401.

[0042] For the inflatable lamp 100 of this application, the reinforcing film 30 is a flexible component, and its edge is fixed to the inner wall of the lamp body 10, which can form a local stress buffer structure. Furthermore, the first transition layer 40 can form a buffer protection between the reinforcing film 30 and the light source 20. During the inflation and expansion process of the lamp body 10, the stress generated by the expansion of the lamp body 10 can be dispersed to the entire inner wall of the lamp body 10 through the reinforcing film 30, avoiding stress concentration around the light source 20 due to rigidity differences. The first transition layer 40 can form a protective layer on the surface of the light source 20, preventing local tearing or damage to the lamp body 10. Furthermore, when the lamp body 10 deflates and curls, the reinforcing film 30 can generate elastic deformation to absorb external pressure and can disperse pressure when the lamp body 10 is curled, preventing the light source component 20 inside the lamp body 10 from being damaged due to excessive compression. In addition, the through holes 401 of the first transition layer 40 can generate radial clamping force on the light-emitting part 22, so that the light-emitting part 22 will not be displaced when the lamp body 10 is inflated and curled up, avoiding misalignment of the light source component 20, ensuring the effective use of the inflatable lamp 100, and ensuring the service life of the inflatable lamp 100.

[0043] In some embodiments of this application, the lamp body 10 is cylindrical, and an installation space is provided inside the lamp body 10. An air vent 101 may be provided on the lamp body 10, communicating with the installation space. An air nozzle 102 may be provided at the air vent 101. The air vent 101 can be opened through the air nozzle 102 to inflate the lamp body 10, thereby causing the lamp body 10 to expand. After the lamp body 10 is fully inflated, the air vent 101 can be sealed by the air nozzle 102 to maintain the lamp body 10 in its inflated cylindrical structure.

[0044] In some examples, the lamp body 10 may include a main body 11, a front cover 12, and a rear cover 13. The main body 11 is a cylindrical shape with openings at both ends and a hollow interior. The front cover 12 and the rear cover 13 are respectively connected to the openings at both ends of the main body 11, and the front cover 12, the main body 11, and the rear cover 13 enclose an installation space. In this example, the air inlet 101 and the air nozzle 102 may be provided on the front cover 12.

[0045] The main body 11 can serve as the main body of a columnar structure, and the front cover 12 and the rear cover 13 can serve as end caps, sealed at both ends of the main body 11 by edge sealing. The front cover 12 and the rear cover 13 can be sealed to the main body 11 by heat fusion welding or sealing rings.

[0046] In some examples, the main body 11 may include a top layer portion 111 and a bottom layer portion 112 connected to each other. The cross-sections of both the top layer portion 111 and the bottom layer portion 112 are C-shaped.

[0047] In this example, the main body 11 can be made of TPU or silicone. Both TPU (thermoplastic polyurethane) and silicone are highly elastic materials. Transparent TPU has a light transmittance of 85%-95%, while silicone has a light transmittance of over 90%. TPU and silicone can meet the requirements for inflation and expansion of the lamp body 10, and also ensure that the light emitted by the light source 20 can pass through smoothly and exit the lamp body 10.

[0048] In specific preparation, TPU can be made into top layer 111 and bottom layer 112 through processes such as extrusion and injection molding; silicone can be made into top layer 111 and bottom layer 112 through compression molding.

[0049] In this application, the light source 20 is disposed in the installation space, and the light emitted by the light source 20 can be emitted to the external environment through the lamp body 10. The side surface of the light source 20 that can emit light is the light-emitting surface 201, and the side surface of the light source 20 opposite to the light-emitting surface 201 is the backlight surface 202.

[0050] In some embodiments of this application, the light source 20 may include a lamp board 21 and a plurality of light-emitting parts 22, which may be spaced apart on the surface of the lamp board 21. In some examples, the light-emitting parts 22 may be LED beads, and the light emitted by the LED beads may be emitted to the external environment through the lamp body 10. The surface of the lamp board 21 on which the light-emitting parts 22 are located is the light-emitting surface 201, and the surface of the lamp board 21 facing away from the light-emitting parts 22 is the backlight surface 202.

[0051] In some examples, the light-emitting surface 201 of the light source 20 faces the top layer 111, and the back light of the light source 20 faces the bottom layer 112. The inner wall of the bottom layer 112 may be white, and the outer wall of the bottom layer 112 may be black.

[0052] The inner wall of the bottom section 112 is made white, so that the side spill light generated by the light source 20 can be reflected back to the installation space by the inner wall of the bottom section 112. The reflected light can be directly directed to the top section 111, and after superimposing with the main light generated by the light-emitting part 22 at the light-emitting surface 201, it is emitted, ensuring the light output rate of the light source 20. The black outer wall of the bottom section 112 can prevent stray light from interfering with the main light, so that the light emitted from the top section 111 comes entirely from the light-emitting surface 201, ensuring the consistency of the light.

[0053] In some examples, the top layer 111 can be made of a light-diffusing TPU film. The light emitted from the light-emitting part 22 can be softened by the light-diffusing TPU film to improve the uniformity of the brightness of the light emitted from the light source 20.

[0054] In this application, a reinforcing film 30 is also provided in the mounting space of the lamp body 10. The reinforcing film 30 is a flexible and transparent material. The reinforcing film 30 is disposed in the mounting space and attached to the light-emitting surface 201 of the light source 20. The edge of the reinforcing film 30 is fixedly connected to the inner wall of the lamp body 10.

[0055] In some embodiments of this application, the reinforcing membrane 30 can be made of TPU or silicone. Both TPU and silicone have high flexibility and tensile strength, which can effectively adapt to the inflation and deflation of the lamp body 10 and its folding and storage after deflation.

[0056] Specifically, when the lamp body 10 is inflated, it expands from a contracted state into a columnar shape. The internal air pressure causes the inner wall of the lamp body 10 to expand outward. The reinforcing membrane 30 can deform accordingly with the expansion of the lamp body 10, preventing excessive stretching of the light source component 20 and thus avoiding damage. After deflation, the lamp body 10 can be rolled up and stored. When the lamp body 10 is rolled up, the reinforcing membrane 30 can undergo elastic deformation to absorb and disperse external pressure, preventing damage to the light source component 20 inside the lamp body 10 due to excessive compression, avoiding pressure failure of the light source component 20, and ensuring the effective use of the inflatable lamp 100.

[0057] In some examples, the reinforcing film 30 may be provided with multiple spaced through holes 301, and the multiple light-emitting parts 22 of the light source 20 are correspondingly inserted into the multiple through holes 301.

[0058] In this example, the aperture of the through hole 301 can be set to be slightly smaller than the outer diameter of the light-emitting part 22. Based on the flexible characteristics of the reinforcing film 30, the reinforcing film 30 can form an interference fit with the light-emitting part 22. This arrangement enables the reinforcing film 30 to generate a radial constraint force on the light-emitting part 22, limiting the offset or tilt of the light-emitting part 22 when the lamp body 10 is inflated and expanded, as well as when it is rolled up and stored, thus ensuring the structural stability of the inflatable rod lamp 100.

[0059] Furthermore, the light-emitting part 22 is inserted through the through hole 301 of the reinforcing film 30, and the light generated by the light-emitting part 22 can be directly directed to the top layer 111 of the lamp body 10 and then directed to the external environment through the top layer 111, effectively reducing light loss and ensuring the light output rate of the light source 20.

[0060] In some examples, the thickness of the reinforcing film 30 can be 0.2 mm. This configuration not only enables the reinforcing film 30 to have better flexibility, allowing it to effectively cope with the inflation and curling of the lamp body 10 and effectively protect the light source 20, but also enables the reinforcing film 30 to reduce the absorption and scattering of light, shorten the path of light transmission, effectively reduce light loss, and improve light output efficiency.

[0061] In some embodiments of this application, the inflatable lamp 100 may further include a first transition layer 40, which is disposed between the reinforcing film 30 and the light source element 20. The first transition layer 40 has a plurality of through holes 401 arranged and connected through each other, and a plurality of light-emitting parts 22 are correspondingly disposed in the plurality of through holes 401. The first transition layer 40 may be foam.

[0062] The first transition layer 40 can form a buffer protection between the reinforcing film 30 and the light source 20. The first transition layer 40 can effectively buffer the vibration and impact of the inflatable lamp 100 during use and ensure the structural stability of the light-emitting part 22.

[0063] Specifically, during use, the lamp body 10 of the inflatable lamp 100 will vibrate due to different usage methods. The first transition layer 40 can buffer the vibration transmitted from the lamp body 10 to the light-emitting part 22, preventing the light-emitting part 22 from falling off due to vibration. Furthermore, when the lamp body 10 is curled, the first transition layer 40 can absorb a certain amount of curling stress through its own deformation, preventing the light source element 20 from breaking due to external curling force and stress concentration, thus ensuring the structural stability of the light source element 20.

[0064] In addition, the via 401 of the first transition layer 40 can generate a radial clamping force on the light-emitting part 22, so that the light-emitting part 22 will not be displaced when the lamp body 10 is inflated and rolled up, ensuring the stability of the relative position of the light source 20 and the lamp body 10, so as to maintain the positioning of the light-emitting part 22 and ensure the stability of the light path.

[0065] In some examples, the thickness of the first transition layer 40 can be 1.5 mm. This configuration allows the first transition layer 40 to effectively adapt to the deformation requirements when the lamp body 10 is rolled up, absorb more rolling stress, reduce the stress transmitted to the light source 20, and more effectively protect the overall structural stability of the light source 20.

[0066] In some embodiments of this application, the inflatable lamp 100 may further include a second transition layer 50, which is disposed on the backlight surface 202 of the lamp panel 21. The second transition layer 50 may be foam.

[0067] When the lamp body 10 is rolled up and stored, the lamp plate 21 will be rolled up or bent accordingly. During this process, the backlight surface 202 of the light source 20 will bear a certain tensile stress. The second transition layer 50 decomposes the stress borne by the backlight surface 202 of the light source 20 by its own stretching and synchronous deformation with the lamp plate 21, thus preventing the light source 20 from being damaged due to bending.

[0068] In this application, the first transition layer 40 and the second transition layer 50 can achieve bidirectional pressure buffering on both sides of the light source 20. The first transition layer 40 can buffer the pressure on the light source 20 on the light-emitting surface 201 side, and the second transition layer 50 can buffer the pressure on the light source 20 on the backlight surface 202 side, thereby achieving comprehensive and effective protection for the light source 20.

[0069] In some examples, the thickness of the first transition layer 40 can be greater than the thickness of the second transition layer 50, which can be 0.5 mm thick. This arrangement allows the second transition layer 50 to provide a buffer on the backlight surface 202 of the light source 20 while avoiding increasing the overall thickness and weight of the inflatable lamp 100, thus maintaining the slim and lightweight characteristics of the inflatable lamp 100 and meeting the requirements of portability and comfortable grip of the inflatable lamp 100.

[0070] In some embodiments of this application, the aspect ratio of the lamp panel 21 can be greater than 5:1, and the lamp panel 21 is elongated. In some examples, the first transition layer 40 and the second transition layer 50 are aligned at their opposite ends in the length direction of the lamp panel 21 in the thickness direction, and the first transition layer 40 and the second transition layer 50 are aligned at their opposite sides in the width direction of the lamp panel 21 in the thickness direction.

[0071] The first transition layer 40 and the second transition layer 50 have the same coverage area in the length and width directions of the lamp plate 21, so that when the lamp body 10 is inflated and rolled up, the first transition layer 40 and the second transition layer 50 can transfer the axial tensile stress to the lamp plate 21, avoid the stress concentration in some areas of the lamp plate 21, and ensure the reliability and light efficiency stability of the light source component 20 in dynamic scenarios such as inflation and rolling.

[0072] In some embodiments of this application, the inflatable lamp 100 may further include an adhesive layer 60. The adhesive layer 60 may be provided on the surface of the first transition layer 40 facing the light source 20, allowing the first transition layer 40 to adhere to the surface of the lamp panel 21 where the light-emitting portion 22 is located. The adhesive layer 60 may also be provided on the surface of the second transition layer 50 facing the light source 20, allowing the second transition layer 50 to adhere to the surface of the lamp panel 21 opposite to the light-emitting portion 22.

[0073] The adhesive layer 60 can form a tight-fitting structure between the first transition layer 40, the second transition layer 50 and the light source component 20, effectively eliminating the gaps between the layers and preventing the relative displacement of the light source component 20, the first transition layer 40 and the second transition layer 50 during the inflation and deflation of the lamp body 10 and the curling of the lamp body 10, thus ensuring the reliability of the internal structure of the inflatable rod lamp 100 and ensuring the stability of the position of the core component.

[0074] Combination Figure 2 and Figure 3 As shown, in some embodiments of this application, the inflatable lamp 100 may further include an electrical connection terminal 71 and a docking portion 72. In this embodiment, the inflatable lamp 100 may further include a control handle 80, which is detachably connected to the rear cover portion 13 of the lamp body 10.

[0075] The side wall of the control handle 80 is designed for hand gripping, facilitating user operation of the inflatable lamp light 100. The control handle 80 internally houses a power supply module and a control module; the power supply module can be a battery. A docking part 72 can be located on the end face of the control handle 80, and this docking part 72 is electrically connected to the power supply module and the control module.

[0076] An electrical connection terminal 71 is provided on the rear cover portion 13 of the lamp body 10, and the electrical connection terminal 71 is electrically connected to the lamp plate 21 of the light source component 20. The end of the electrical connection terminal 71 protrudes from the surface of the rear end face, and multiple electrical connection terminals 71 can be provided and arranged at intervals.

[0077] The control handle 80 is detachably connected to the lamp body 10, so that the electrical connection terminal 71 and the docking part 72 are docked to form an electrical connection, so that the power supply module and the control module can form an electrical connection with the light source 20, thereby enabling the power supply module to supply power to the light source 20 and the control module to control the light emission of the light source 20.

[0078] In this application, the control handle 80 is detachably connected to the lamp body 10. The disassembled control handle 80 and lamp body 10 can be stored separately, reducing the overall space occupied by the inflatable lamp 100. Furthermore, if the power supply module is out of power or damaged, the control handle 80 can be disassembled separately to replace or recharge the power supply module; if the lamp body 10 malfunctions, it can be repaired separately without replacing the entire unit, effectively reducing maintenance costs. In addition, based on the detachable connection between the control handle 80 and the lamp body 10, users can expand the functionality according to their needs, such as adapting the lamp body 10 to control handles 80 with different functions, or adapting the control handle 80 to different types of lamp bodies 10, improving the product's versatility.

[0079] In some examples, the mating portion 72 may protrude from the end face of the control handle 80, and the mating portion 72 may include a plurality of slots 721. When the control handle 80 is detachably connected to the lamp body 10, the electrical connection terminal 71 can be inserted into the slots 721 of the mating portion 72 to form an electrical connection.

[0080] In this example, the mating part 72 protrudes from the end face of the control handle 80, making it easier to align the control handle 80 with the lamp body 10. Users can more intuitively align the electrical connection terminal 71 of the lamp body 10 with the slot 721 of the mating part 72 on the control handle 80, reducing the difficulty of the connection operation and improving assembly efficiency. Furthermore, the insertion and engagement of the slot 721 of the mating part 72 and the electrical connection terminal 71 provides a relatively stable connection. After the electrical connection terminal 71 is inserted into the slot 721, it will make tight contact with the inner wall of the slot 721, forming a reliable physical and electrical connection. This reduces the occurrence of poor contact due to loosening or shaking, ensuring the stability of the circuit connection of the inflatable lamp 100 during operation, thereby ensuring the normal operation of the equipment.

[0081] In some examples, the mating part 72 may also be configured to include contacts. When the control handle 80 is detachably connected to the lamp body 10, the electrical connection terminal 71 can abut against the contacts of the mating part 72 to form an electrical connection.

[0082] In this example, the contacts can be integrated with an elastic structure. When the electrical terminal 71 comes into contact with the contact, the elastic structure will undergo a certain elastic deformation. When the inflatable lamp 100 vibrates during use, the elastic structure will undergo a slight displacement to adaptively compensate for the offset caused by the vibration, avoiding interruption of contact between the electrical terminal 71 and the contact due to vibration displacement, and ensuring the stability of the circuit connection.

[0083] like Figure 2 and Figure 3As shown, in some embodiments of this application, the inflatable light stick 100 may further include a positioning post 73 and a positioning pusher 74. The positioning post 73 is telescopically disposed on the end face of the control handle 80 where the docking portion 72 is provided, and the positioning pusher 74 is connected to the positioning post 73. The positioning pusher 74 is movably disposed on the outer wall of the control handle 80 to control the end of the positioning post 73 to protrude outward from the end face of the control handle 80 or to be received inward into the interior of the control handle 80.

[0084] The lamp body 10 has a positioning hole 103 on the rear cover 13. The end of the positioning post 73 protrudes outward from the end face of the control handle 80 and is fixed in the positioning hole 103, so that the lamp body 10 and the control handle 80 can be detachably connected.

[0085] In some examples, the positioning post 73 can be connected to the control handle 80 via a spring. One end of the positioning post 73 is connected to the spring, and the other end protrudes from the end face of the control handle 80. The portion of the positioning post 73 protruding from the end face of the control handle 80 can engage with the positioning hole 103 on the end face of the lamp body 10, achieving a detachable connection between the lamp body 10 and the control handle 80. The positioning post 73 and the positioning hole 103 can be interference-fitted. Moving the positioning pusher 74 controls the positioning post 73 to retract inward into the control handle 80, causing the positioning post 73 to exit from the positioning hole 103, thus separating the lamp body 10 from the control handle 80.

[0086] In some embodiments of this application, the end face of the control handle 80 with the mating portion 72 is also provided with a connecting portion 75, and the surface of the lamp body 10 with the electrical connection terminal 71 is also provided with an assembly portion 104. When the control handle 80 and the lamp body 10 are detachably connected, the connecting portion 75 and the assembly portion 104 can be adapted to connect.

[0087] In some examples, such as Figure 2 As shown, the connecting portion 75 protrudes from the end face of the control handle 80. The connecting portion 75 may include a cylindrical section 751 connected to the end face of the control handle 80 and a latch 752 disposed at the end of the cylindrical section 751 facing away from the control means, with the edge of the latch 752 extending outward beyond the periphery of the cylindrical section 751. In this example, two connecting portions 75 may be provided, and the two connecting portions 75 may be disposed opposite each other on both sides of the mating portion 72. In other examples, the number of connecting portions 75 is not limited to two; it may be one, three, four, etc.

[0088] The mounting portion 104 on the lamp body 10 has a hole-like structure. The mounting portion 104 may include a first fixing area 1041 and a second fixing area 1042 that are connected to each other. The diameter of the second fixing area 1042 is smaller than the diameter of the first fixing area 1041. Corresponding to the two connecting portions 75, two mounting portions 104 may be provided, and the two mounting portions 104 are respectively arranged opposite to each other on both sides of the electrical connection terminal 71.

[0089] When the control handle 80 is connected to the lamp body 10, the latch 752 can extend into the first fixing area 1041 and move the control handle 80 and the lamp body 10 relative to each other, so that the column section 751 passes through the second fixing area 1042 and the latch 752 is engaged in the inner wall of the second fixing area 1042, thereby positioning and connecting the control handle 80 and the lamp body 10.

[0090] In this configuration, the buckle 752 can extend into the first fixing area 1041. After the relative movement of the control handle 80 and the lamp body 10, the column section 751 passes through the second fixing area 1042, and the buckle 752 is engaged in the inner wall of the second fixing area 1042. This structure utilizes the cooperation between the buckle 752 and the fixing area to form a stable locking connection, which can effectively prevent the control handle 80 and the lamp body 10 from accidentally separating due to vibration, external force pulling, etc. during use, ensuring the stability of the overall structure of the inflatable lamp 100 and ensuring that the inflatable lamp 100 can work normally.

[0091] When the column section 751 penetrates the second fixed area 1042, it plays a precise positioning role, limiting the relative displacement of the control handle 80 and the lamp body 10 in all directions, making the connection between the two more stable, further enhancing the reliability of the entire connection structure, ensuring the stability of the electrical connection between the electrical terminal 71 and the docking part 72, and facilitating the normal operation of the inflatable rod lamp 100.

[0092] With the positioning post 73 and positioning hole 103 combined, after the connecting part 75 and the assembly part 104 are adapted and connected, the positioning post 73 is moved by the positioning pusher 74 so that the end of the positioning post 73 protrudes outward from the end of the control handle 80, and the control handle 80 and the lamp body 10 are effectively locked by the engagement of the positioning post 73 and the positioning hole 103.

[0093] In some examples, guide blocks 76 may protrude from the end face of the control handle 80 where the mating portion 72 is located. Two guide blocks 76 may be provided, with the two guide blocks 76 respectively located on both sides of the mating portion 72. In other examples, the number of guide blocks 76 is not limited to two; it may be one, three, four, etc.

[0094] The rear cover 13 of the lamp body 10 is provided with guide holes 105. There are two guide holes 105, which are respectively located on both sides of the electrical connection terminal 71. The guide block 76 is rectangular, and the guide holes 105 are correspondingly rectangular to fit the guide block 76.

[0095] The matching mating of the guide block 76 and the guide hole 105 can provide connection guidance when the lamp body 10 is connected to the control handle 80, ensuring that the control handle 80 and the lamp body 10 can be quickly and accurately aligned when connected, so that the mating part 72 and the electrical connection terminal 71 can be accurately matched, avoiding poor connection or abnormal function caused by deviation, and helping to improve the assembly quality and stability of the product.

[0096] like Figure 4 and Figure 5 As shown, in some embodiments of this application, the control handle 80 may further include a detachably connected housing 81 and a handle member 82. The outer wall of the handle member 82 is available for hand gripping, and the housing 81 has a docking portion 72 at the end opposite to the handle member 82, and the control module may be disposed inside the housing 81.

[0097] The power supply module is a battery, which is located inside the handle component 82. The end face of the handle component 82 has a power supply contact 77, and the surface of the housing 81 opposite to the mating portion 72 has a conductive terminal 78. The housing 81 and the handle component 82 are detachably connected, allowing the conductive terminal 78 to abut against the power supply contact 77 to form an electrical connection, thereby connecting the battery to the control module.

[0098] The handle 82 has a built-in battery and is detachably connected to the housing 81. When the battery is depleted, the user can easily replace the battery by simply detaching the handle 82 from the housing 81. This greatly improves the battery life and ease of use of the inflatable light stick 100 in scenarios where charging is not readily available, such as outdoor shooting or emergency lighting.

[0099] In this embodiment, such as Figure 3 and Figure 4 As shown, the docking part 72 is provided on the end face of the box body 81 opposite to the handle part 82. The end face of the box body 81 with the docking part 72 is also provided with a connecting part 75, a guide block 76 and a positioning post 73; and the positioning pusher 74 is movably provided on the side wall of the box body 81.

[0100] In some examples, the inflatable stick light 100 may include a display screen 791, an operation button 792, and an operation knob 793. The display screen 791, operation button 792, and operation knob 793 may be located on the side of the housing 81, and the display screen 791, operation button 792, and operation knob 793 may be electrically connected to the control module inside the housing 81.

[0101] The display screen 791 can be used to display parameters such as color, color temperature, brightness, and dynamic lighting effects of the light source 20, as well as representative symbols, graphics, or text information related to the mode, and parameter information that changes as the user adjusts the corresponding parameters.

[0102] Based on the electrical connection between the control module and the light source 20, the user can operate and control the light source 20 through the operation button 792 and the operation knob 793, such as controlling the opening / closing of the light source 20, adjusting the light emission mode, and adjusting the light emission parameters.

[0103] In some embodiments of this application, combined with Figure 4 and Figure 6 As shown, the control handle 80 includes a connecting post 83 and a connecting pusher 84. The connecting post 83 is telescopically disposed on the end face of the handle member 82. The connecting pusher 84 is connected to the connecting post 83 and is movably disposed on the handle member 82 to control the end of the connecting post 83 to protrude outward from the end face of the handle member 82 or to be received inward into the interior of the handle member 82.

[0104] The end face of the box body 81 with conductive terminal 78 has a connection hole 811. The end of the connecting post 83 protrudes outward from the end face of the handle 82 and is fixed in the connection hole 811, so that the box body 81 and the handle 82 can be detachably connected.

[0105] In some examples, the connecting post 83 can be connected to the handle 82 via a spring. One end of the connecting post 83 is connected to the spring, and the other end of the connecting post 83 protrudes from the end face of the handle 82. The portion of the connecting post 83 protruding from the end face of the handle 82 can engage with the connecting hole 811 on the end face of the housing 81, achieving a detachable connection between the housing 81 and the handle 82. The connecting post 83 and the connecting hole 811 can be interference-fitted.

[0106] The movable connection pusher 84 can control the connecting post 83 to be received inward into the handle part 82, so that the connecting post 83 can be withdrawn from the connecting hole 811, thereby realizing the separation of the box 81 and the handle part 82.

[0107] In some examples, combined Figure 4 and Figure 5 As shown, a mating post 85 can be provided on the end face of the housing 81 where the connecting hole 811 is provided, and a mating hole 821 can be provided on the end face of the handle 82. When the housing 81 and the handle 82 are connected, the mating post 85 can be fitted through the mating hole 821. The cooperation between the mating post 85 and the mating hole 821 can provide guidance when the housing 81 and the handle 82 are connected, ensuring the accuracy of the connection between the two.

[0108] like Figure 4As shown in some embodiments of this application, the end of the handle 82 facing away from the housing 81 may be provided with a mounting hole 822 and a screw hole 823. The mounting hole 822 can mate with a frame having a protruding mounting head to connect and assemble the inflatable light 100 to the frame. The screw hole 823 is used to mount the inflatable light 100 on a desktop or floor-standing frame, enabling both handheld and stand-mounted use of the inflatable light 100.

[0109] Furthermore, in some embodiments of this application, the inflatable light stick 100 may also include a bracket 90. The bracket 90 is movably connected to the housing 81 and is used to fix and / or connect external photographic or video recording equipment to an external mounting surface. In some examples, the bracket 90 can be snapped into and slidably mounted on the housing 81 via a slot.

[0110] The bracket 90 allows users to quickly adjust the position and angle of the inflatable light 100 during use without disassembly and reinstallation, saving time and effort. Users can flexibly adjust the state of the inflatable light 100 at any time according to changes in the subject being photographed or lighting needs, improving work efficiency. Furthermore, the bracket 90 can connect to external photography and video equipment, forming a unified working system between the inflatable light 100 and the equipment. This helps to better coordinate the positional relationship between the light and the shooting equipment during shooting, enhancing the user experience.

[0111] For the inflatable lamp of this application, the reinforcing film is a flexible component, its edges fixed to the inner wall of the lamp body, forming a local stress buffer structure. Furthermore, the first transition layer provides buffer protection between the reinforcing film and the light source component. During the inflation process, the stress generated by the lamp body's expansion is dispersed throughout the entire inner wall of the lamp body through the reinforcing film, preventing stress concentration around the light source component due to rigidity differences. The first transition layer provides protection on the surface of the light source component, preventing localized tearing or damage to the lamp body. Moreover, when the lamp body deflates and curls, the reinforcing film undergoes elastic deformation to absorb external pressure and disperses pressure during curling, preventing damage to the light source component inside the lamp body due to excessive compression. Additionally, the perforations in the first transition layer generate a radial clamping force on the light-emitting part, preventing displacement of the light-emitting part during inflation and curling, avoiding misalignment of the light source component, ensuring the effective use of the inflatable lamp, and guaranteeing its service life.

[0112] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
