Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to a foldable flexible lighting device. Background Technology

[0002] As lighting needs become more diverse, users are increasingly demanding greater portability and adaptability from lighting fixtures: in home settings, handheld lamps are needed to illuminate small spaces when repairing cabinets or ceilings; during outdoor camping, lightweight and portable lamps are required to provide lighting inside tents and around campsites; and in emergency situations, lamps need to be quick to deploy and adaptable to different placement angles.

[0003] Currently, existing mainstream folding lighting devices have significant technical shortcomings, making it difficult to meet the core requirements of "multi-angle adaptation and multi-carrier fixation" in temporary lighting scenarios. On the one hand, most products adopt a "rigid frame + folding hinge" structure (such as folding table lamps and camping lamps). Although they can be folded for storage, due to insufficient flexibility, they can only be folded in one direction along the hinge. They cannot conform to the curved surfaces such as the inner wall of camping tents or the outer shell of cylindrical equipment for curved surface lighting. Moreover, after folding, they still need to be placed on a flat surface and cannot be fixed on non-planar carriers such as tree branches or tent poles, thus limiting their usage scenarios. On the other hand, some lighting devices that claim to be "flexible" only achieve slight bending through flexible lamp panels without a matching folding and fixing structure. This causes the lamp panels to easily sag and shift due to their own weight after unfolding, making it impossible to stably maintain the preset lighting direction, further restricting the practicality and adaptability of the device.

[0004] To address this, a foldable flexible lighting device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a foldable flexible lighting device that addresses the significant technical shortcomings of existing mainstream foldable lighting devices, which struggle to meet the core requirements of "multi-angle adaptation and multi-carrier fixation" in temporary lighting scenarios. On the one hand, most products adopt a "rigid frame + folding hinge" structure (such as folding table lamps and camping lamps). Although they can be folded for storage, their lack of flexibility means they can only fold in one direction along the hinge, making it impossible to conform to the curved surfaces of camping tents, cylindrical equipment shells, etc., for curved surface lighting. Furthermore, after folding, they still rely on flat placement and cannot be fixed to non-planar carriers such as tree branches and tent poles, limiting their application scenarios. On the other hand, some lighting devices that claim to be "flexible" only achieve slight bending through a flexible lamp panel without a matching folding and fixing structure. This causes the lamp panel to easily sag and shift due to its own weight after unfolding, making it impossible to stably maintain the preset lighting direction, further restricting the practicality and adaptability of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foldable flexible lighting device, comprising a flexible lamp body assembly, wherein a folding fixing assembly is provided on the rear side of the flexible lamp body assembly, and a power supply assembly is provided on the left side of the flexible lamp body assembly;

[0007] The flexible lamp assembly includes a flexible PCB lamp board made of polyimide substrate. LED beads are soldered to the front side of the flexible PCB lamp board, and the front side of the flexible PCB lamp board is coated with white solder resist ink. A light guide resin layer covers the outside of the LED beads, and a transparent silicone protective layer is wrapped around the outside of the flexible PCB lamp board.

[0008] Preferably, the folding fixing assembly includes folding straps, which are respectively fixedly connected to both sides of the back side of the transparent silicone protective layer.

[0009] Preferably, the rear side of the folded strap is provided with anti-slip fixing holes spaced apart, and the right side of the right folded strap is sewn with a Velcro backing.

[0010] Preferably, the left side of the left folding strip is sewn with a Velcro side, and the middle and both sides of the back side of the transparent silicone protective layer are provided with magnetic structures.

[0011] Preferably, the magnetic attraction structure includes a fixing groove, which is respectively formed in the middle and on both sides of the back side of the transparent silicone protective layer.

[0012] Preferably, an insulating plastic shell is bonded to the inside of the fixing groove, and a magnetic adsorption sheet is provided inside the insulating plastic shell. The magnetic adsorption sheet is made of neodymium iron boron strong magnetic material.

[0013] Preferably, the power supply component includes a battery box, which is disposed on the left side of the flexible PCB lamp board. A lithium battery is disposed inside the battery box, and the lithium battery is electrically connected to the flexible PCB lamp board through a flexible wire.

[0014] Preferably, a switch button is provided on the left side of the battery box, a charging interface is embedded in the left side of the battery box, and a power indicator light is embedded in the left side of the battery box.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up a flexible lamp body assembly and a folding fixing assembly. The flexible lamp body assembly is based on a flexible PCB lamp board with polyimide substrate and is equipped with a transparent silicone protective layer to achieve good flexibility. It can fit the inner wall of camping tents, cylindrical equipment shells and other curved surfaces for curved surface lighting. This solves the problem that the existing "rigid frame + folding hinge" structure can only be folded in one direction and cannot adapt to curved surfaces. The folding fixing assembly can help fix the device to non-planar carriers such as tree branches and tent poles, while preventing the flexible lamp board from drooping and shifting due to its own weight after unfolding. It can stably maintain the preset lighting direction and make up for the shortcomings of existing flexible lighting devices that lack adaptable fixing structures and have limited practicality.

The entire operation and battery life management can be completed without additional tools, effectively meeting the needs of rapid deployment and use of lights in emergency scenarios, and solving the problems of inconvenient operation and unclear battery life status of existing devices in emergency scenarios.

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A foldable flexible lighting device includes a flexible lamp body assembly 1, a folding fixing assembly 2 disposed on the rear side of the flexible lamp body assembly 1, and a power supply assembly 3 disposed on the left side of the flexible lamp body assembly 1.

[0029] The flexible lamp assembly 1 includes a flexible PCB lamp board 11, which is made of polyimide substrate. LED beads 12 are soldered to the front side of the flexible PCB lamp board 11. The front side of the flexible PCB lamp board 11 is coated with white solder resist ink 13. A light guide resin layer 14 is covered on the outside of the LED beads 12. A transparent silicone protective layer 15 is wrapped on the outside of the flexible PCB lamp board 11.

[0030] In this embodiment, a collaborative lighting system is formed by setting up a flexible lamp body assembly 1, a folding and fixing assembly 2, and a power supply assembly 3. The flexible PCB lamp board 11 with polyimide substrate provides basic flexible support for the whole. The LED beads 12 welded on its front side serve as the light source. The brightness is enhanced by the reflection of white solder resist ink 13. The light guide resin layer 14 makes the light diffuse evenly. The outer transparent silicone protective layer 15 protects the flexible PCB lamp board 11 and LED beads 12 without affecting the light transmission. Together, they form a flexible lighting body to meet the curved surface lighting requirements of the curved surface. The folding and fixing assembly 2, in conjunction with the flexible characteristics of the flexible PCB lamp board 11, can not only help fix the device to the non-planar carrier, but also prevent the lamp board from sagging due to its own weight, ensuring the stability of the lighting direction. The power supply assembly 3 provides continuous power to the LED beads 12 of the flexible PCB lamp board 11, realizing rapid control and power management of the lighting function. The three work together to make the device flexible and adaptable, capable of fixing in multiple scenarios, and convenient in power supply, thus comprehensively improving the practicality of temporary lighting.

[0031] Specifically, such as Figure 3 As shown, the folding fixing component 2 includes a folding strap 21, which is fixedly connected to both sides of the back side of the transparent silicone protective layer 15.

[0032] Specifically, such as Figure 3 As shown, anti-slip fixing holes 22 are spaced apart on the back side of the folding strap 21, and a Velcro backing 23 is sewn onto the right side of the right folding strap 21.

[0033] Specifically, such as Figure 3 As shown, the left side of the left folding strip 21 is sewn with a Velcro side 24, and the back of the transparent silicone protective layer 15 is provided with magnetic structures 25 in the middle and on both sides.

[0034] In this embodiment: By setting the folding fixing component 2, two folding straps 21 are respectively fixed to the two sides of the back of the transparent silicone protective layer 15, forming a symmetrical support structure, which lays a stable foundation for fixing the device in multiple scenarios. When the device needs to be fixed, the folding straps 21 can bend synchronously with the bending of the flexible PCB lamp board 11 and the transparent silicone protective layer 15. Since the folding straps 21 are directly fixed to the transparent silicone protective layer 15, they can fully adapt to the bending shape of the lamp body, avoiding the situation where the folding straps 21 are separated from the lamp body. At this time, the anti-slip fixing holes 22 on the back of the folding straps 21 can fit tightly against non-planar carriers such as tree branches and tent poles, effectively preventing slippage during fixing. The Velcro female side 23 of the right folding strap 21 and the Velcro female side 24 of the left folding strap 21 form a precise fit, which can tightly fit the device when it is folded and stored. The flexible PCB light board 11 is designed to be compact and portable, and can be used in curved lighting or fixed environments. The Velcro fasteners allow the flexible PCB light board 11 to be stably attached to the outside of tree branches or tent poles in a semi-circular shape, ensuring a seamless fit between the light board and the carrier. At the same time, the magnetic structure 25 on the back of the transparent silicone protective layer 15 can quickly adhere to the surface of iron objects such as iron poles and iron sheets, complementing the mechanical fixing method of the folding strap 21. This further expands the applicable fixing scenarios of the device. The overall design, through the combination of "anti-slip fixing holes 22 + Velcro + magnetic attraction", not only ensures the stability of the device on non-planar carriers, but also provides upward support for the unfolded flexible PCB light board 11, preventing it from sagging or shifting due to its own weight, and ultimately ensuring precise and controllable lighting direction.

[0035] Specifically, such as Figure 4 As shown, the magnetic structure 25 includes a fixing groove 251, which is respectively opened in the middle and on both sides of the back side of the transparent silicone protective layer 15.

[0036] Specifically, such as Figure 4 As shown, an insulating plastic shell 252 is bonded to the inside of the fixing groove 251, and a magnetic adsorption sheet 253 is provided inside the insulating plastic shell 252. The magnetic adsorption sheet 253 is made of neodymium iron boron strong magnet material.

[0037] In this embodiment: by setting up a magnetic attraction structure 25, the fixing groove 251 is opened in the middle and on both sides of the back side of the transparent silicone protective layer 15, providing precise positioning for component installation. The insulating plastic shell 252 bonded in the fixing groove 251 can not only fix the magnetic adsorption sheet 253, but also prevent the magnetic adsorption sheet 253 from contacting the circuit of the flexible PCB light board 11 and causing a short circuit. The magnetic adsorption sheet 253, which uses neodymium iron boron strong magnetic material, has strong adsorption force and can be quickly adsorbed on metal carriers such as metal equipment shells and camping cookware without additional fixing operations. Moreover, the design of multiple adsorption points in the middle and on both sides can evenly distribute the adsorption force and prevent the device from shifting due to single-point force, achieving stable fixation on the metal carrier and further expanding the applicable scenarios of the device.

[0038] Specifically, such as Figure 5 As shown, the power supply component 3 includes a battery box 31, which is located on the left side of the flexible PCB lamp board 11. A lithium battery 32 is disposed inside the battery box 31, and the lithium battery 32 is electrically connected to the flexible PCB lamp board 11 through a flexible wire.

[0039] Specifically, such as Figure 5 As shown, a switch button 33 is provided on the left side of the battery box 31, a charging interface 34 is embedded in the left side of the battery box 31, and a power indicator light 35 is embedded in the left side of the battery box 31. The power indicator light 35, the charging interface 34 and the switch button 33 are all electrically connected to the lithium battery 32.

[0040] In this embodiment: By setting the power supply component 3, the battery box 31 is located on the left side of the flexible PCB lamp board 11, which does not affect the bending of the flexible PCB lamp board 11. The internal lithium battery 32 is electrically connected to the flexible PCB lamp board 11 through a flexible wire. The flexible wire can bend synchronously with the flexible PCB lamp board 11 to ensure the stability of the power supply link. Pressing the switch button 33 on the left side of the battery box 31 can quickly turn the circuit on and off, realizing the start and stop of the LED beads 12. When the power is low, the power can be conveniently replenished through the embedded charging interface 34. The embedded power indicator 35 provides real-time feedback on the remaining power of the lithium battery 32, making it convenient for users to monitor the battery status. The overall structure can be operated without additional tools, meeting the needs of rapid deployment of lighting in emergency scenarios, while ensuring continuous and stable power supply.

[0041] Specifically, such as Figure 2 As shown, the front side of the transparent silicone protective layer 15 is coated with an anti-scratch coating 4, which is made of polycarbonate.

[0042] Specifically, such as Figure 3 As shown, a rubber anti-slip ring 5 is bonded inside the anti-slip fixing hole 22, and anti-slip texture is provided on the back side of the rubber anti-slip ring 5.

[0043] In this embodiment: the polycarbonate anti-scratch coating 4 coated on the front side of the transparent silicone protective layer 15, with its high hardness and wear resistance, can directly resist minor scratches during daily use, preventing scratches from forming on the surface of the transparent silicone protective layer 15. This not only prevents scratches from blocking light and affecting the lighting effect, but also protects the flexible PCB lamp board 11 and LED beads 12 on the inner side, extending the overall appearance integrity of the device and the service life of the lighting function. The rubber anti-slip ring 5 bonded inside the anti-slip fixing hole 22 has anti-slip textures that increase the contact friction with cylindrical non-planar carriers such as folding straps 21, branches, or tent poles. When the device is fixed through the anti-slip fixing hole 22, it can effectively prevent the fixing part from slipping and loosening, further improving the fixing stability of the device on non-planar carriers, and ensuring that the lighting direction will not be deviated due to accidental sliding during the lighting process.

[0044] Working Principle: When using the foldable flexible lighting device, the fixing method and lighting form must first be determined according to the actual lighting scenario (such as home repair, outdoor camping, emergency lighting). Stable lighting is then achieved through the coordinated operation of each component. First, the device needs to be prepared and fixed: If it needs to be fitted to curved surfaces such as the inner wall of a tent or the outer shell of cylindrical equipment, or fixed to non-planar carriers such as tree branches or tent poles, the flexible lamp body component 1 can be bent first. Because the flexible PCB lamp board 11 uses polyimide substrate, it has good flexibility. When bent, it will cause the outer transparent silicone protective layer 15 to deform synchronously. The folding strips 21 fixed on both sides of the back of the transparent silicone protective layer 15 will bend synchronously with the lamp body, preventing it from detaching from the lamp body. At this time, if fixed to tree branches or tents… The rod allows the folding strap 21 to wrap around the carrier, making the anti-slip fixing hole 22 on the back of the folding strap 21 fit against the carrier surface. The anti-slip texture of the rubber anti-slip ring 5 inside the hole increases the contact friction with the carrier and prevents slippage. At the same time, the Velcro female side 23 of the right folding strap 21 and the Velcro female side 24 of the left folding strap 21 are engaged, so that the flexible PCB lamp board 11 is tightly wrapped around the outside of the carrier in a semi-circular arc, ensuring that the lamp body and the carrier fit together without gaps. If it is necessary to fix it to a metal carrier such as an iron rod or iron sheet, the magnetic attraction structure 25 on the middle and both sides of the back of the transparent silicone protective layer 15 can directly play its role. The neodymium iron boron strong magnetic adsorption sheet 253 wrapped in the insulating plastic shell 252 in the fixing groove 251 can quickly adsorb onto the metal surface, and the multi-adsorption point design can evenly distribute the adsorption. The attachment prevents the device from shifting and, together with the folding strap 21, achieves stable fixation. After fixation, the lighting function is activated: Pressing the switch button 33 on the left side of the battery box 31, the lithium battery 32 inside the battery box 31 supplies power to the flexible PCB lamp board 11 through a flexible wire (which can deform synchronously with the bending of the lamp body to ensure the stability of the power supply link). The LED beads 12 soldered on the front side of the flexible PCB lamp board 11 are powered on and emit light. During the lighting process, the white solder resist ink 13 coated on the front side of the flexible PCB lamp board 11 reflects the light of the LED beads 12, reducing light loss and enhancing brightness. The light guide resin layer 14 covering the outside of the LED beads 12 converts the point light source into a uniform surface light source, avoiding light spots. The light finally passes through the polycarbonate layer on the front side of the transparent silicone protective layer 15. The ester-based scratch-resistant coating 4 (which resists minor scratches, protects the lamp body, and ensures unobstructed light) emits light, creating a stable and uniform illumination effect. During use, the battery level can be monitored and managed in real time: the remaining power of the lithium battery 32 can be clearly seen through the power indicator light 35 embedded on the left side of the battery box 31, preventing insufficient power from affecting use. When the power is low, it can be easily replenished directly through the embedded charging port 34 without removing the battery, requiring no additional tools. This is especially suitable for the need for rapid deployment of lighting in emergency scenarios. Furthermore, the scratch-resistant coating 4 on the front of the transparent silicone protective layer 15 protects its appearance and lighting effect during daily use, extending the device's lifespan. The rubber anti-slip ring 5 inside the anti-slip fixing hole 22 continuously ensures the stability of the fixing part.To prevent accidental sliding of the device during lighting and subsequent deviation in lighting direction, the components work together through a combination of flexible adaptation, multi-mode fixing, stable power supply, and long-term protection to achieve precise and stable lighting in various scenarios.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
