[0001] This invention relates to the field of lighting technology, and in particular to a light-emitting component, lighting device, and equipment. Background Technology

[0002] Flexible LED strips, a common lighting device, are widely used in home, commercial, and decorative lighting applications due to their flexibility, ease of installation, and uniform light output. In related technologies, flexible LED strips typically consist of a flexible frame and LED chips and circuitry installed within it. Electrical connections are achieved by soldering the circuitry to the substrates (i.e., circuit boards) of adjacent LED chips. However, during bending or twisting of the flexible LED strip, the solder joints between the circuitry and the substrate are prone to breakage due to stress concentration, leading to LED chip failure or partial blackouts, affecting the overall lighting effect and lifespan.

[0005] In some embodiments, the lighting unit has a heat sink on the side away from the lamp bead, the heat sink is insulated from the conductive line, and the heat sink at least covers the area where the lamp bead is located.

[0006] In some embodiments, the perforation extends through opposite sides of the lighting unit, the electrical connection terminal and the lamp bead are located on the same side of the lighting unit, and the electrical connection terminal is located at the periphery of the perforation. One end of the electrical connector enters the perforation from the side of the lighting unit away from the lamp bead and extends to the side of the lighting unit facing the lamp bead, where it is electrically connected to the electrical connection terminal.

[0007] In some embodiments, the perforation is a blind hole, at least a portion of the electrical connection terminal is located at the bottom of the perforation, and one end of the electrical connector is inserted into the perforation from the side of the lighting unit away from the lamp bead and electrically connected to the electrical connection terminal.

[0008] A second aspect of the present invention provides a lighting device comprising: Multiple light-emitting components as described in any of the above embodiments; A flexible base shell having an accommodating space extending along a first direction, and the flexible base shell including a second base plate and second side plates connected to opposite sides of the second base plate, the second base plate being configured as a flexible transparent structure; and A support member is installed within the accommodating space, and the support member is attached to the second base plate. The support member is configured as a flexible support body that can be elastically deformed. Each of the light-emitting components and the support member is housed within the accommodating space, and each of the light-emitting components is located on the side of the support member away from the second base plate, with the lamp beads facing the second base plate, and each of the lighting units is connected in series and / or in parallel through the electrical connector.

[0009] In some embodiments, the side of the second side plate facing the accommodating space has a first limiting groove communicating with the accommodating space. The first limiting groove has a first wall surface and a second wall surface opposite to each other along a second direction. The second direction is parallel to the direction from the light-emitting component to the support member. The support member has a first surface and a second surface opposite to each other along the second direction. The first surface abuts against the first wall surface, the second surface abuts against the second wall surface, and the second wall surface is coplanar with the surface of the side of the second bottom plate facing the accommodating space.

[0010] In some embodiments, the side of the second side plate facing the accommodating space also has a second limiting groove communicating with the accommodating space, the second limiting groove being arranged at an interval from the first limiting groove, and the lighting unit being fitted into the second limiting groove.

[0011] In some embodiments, the lighting device further includes a housing, the housing including a first base plate and first side plates connected to opposite sides of the first base plate, the two first side plates and the first base plate together defining an installation space with an opening on one side, the housing being configured as a rigid structure, wherein one of the first side plates has a first protrusion facing the installation space, and a second side plate has a first groove facing the outer side of the first side plate, the first protrusion passing through the first groove.

[0012] In some embodiments, the lighting device further includes a focusing assembly, wherein multiple focusing assemblies are provided, each focusing assembly being arranged corresponding to each of the lamp beads. Each focusing assembly includes a focusing element and a diaphragm covering the focusing element. The diaphragm is disposed between the focusing element and the second base plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: In the technical solution of this invention, by setting perforations to allow electrical connectors to pass through from the back of the lighting unit and connect to the electrical connection terminals, the bending stress generated by the lighting device in bending or torsional use is dispersed to the perforation wall and the lighting unit body. This greatly reduces stress concentration at the connection point between the electrical connectors and the lighting unit, thereby significantly improving mechanical reliability and service life under repeated bending conditions. The layout of the electrical connectors on the back of the lighting unit achieves physical isolation between the circuit system and the light-emitting surface, protecting the connection points from external damage and providing sufficient space for the optical design of the light-emitting surface, which helps to achieve more uniform light emission and a more compact arrangement. In addition, the perforations provide precise positioning and stable connection of the electrical connectors, effectively preventing poor contact caused by vibration or deformation, improving electrical safety and the stability of current signal transmission, and ensuring the lighting quality of the light-emitting components.

[0018] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] In related technologies, flexible LED strips contain multiple circuit boards, which are electrically connected by wires. Specifically, the circuit boards are etched with circuit structures and have light-emitting diodes (LEDs) soldered onto them. To provide a stable power supply to the LEDs, the wires sequentially connect the positive and negative terminals of adjacent circuit boards, thereby achieving conductivity and ensuring continuous light emission throughout the LED strip. In these technologies, one end of the wire is directly soldered to a pad on the circuit board, and the other end extends to an adjacent circuit board and connects to its corresponding polarity pad. The wire and the pad are located on the same side of the circuit board. However, in scenarios where the flexible LED strip is bent or twisted, the wires are subjected to stress due to the deformation of the strip. This stress concentrates at the connection between the wire and the pad, easily leading to fatigue fracture of the wire solder joints, which in turn causes local circuit breaks, affecting the overall luminous stability and lifespan of the LED strip.

[0021] In view of this, please refer to Figure 3 and Figure 4The first aspect of this application provides a light-emitting component 110, which includes an illumination unit 111, an LED chip 112, and an electrical connector 113. The illumination unit 111 has an electrical connection terminal 1112 and a conductive line, and the electrical connection terminal 1112 is electrically connected to the conductive line to transmit current. It is understood that the conductive line can be formed on the illumination unit 111 using an etching process. The LED chip 112 is mounted on the illumination unit 111 and electrically connected to the conductive line for emitting light. The electrical connector 113 is electrically connected to the electrical connection terminal 1112. The electrical connector 113 can be a conductive structure such as a wire or a conductive sheet, with one end fixedly connected to the electrical connection terminal 1112 and the other end used to connect to an external power source or a corresponding electrical connection terminal 1112 of an adjacent light-emitting component 110. The lighting unit 111 also has a through hole 1113. One end of the electrical connector 113 passes through the through hole 1113 from the side of the lighting unit 111 away from the lamp bead 112 and is electrically connected to the electrical connection terminal 1112. The other end extends outside the lighting unit 111 to realize the input or output of external power. Thus, the electrical connector 113 can safely and effectively complete the power transmission task without interfering with the operation of the lamp bead 112, improving the overall stability and reliability of the component. By inserting the electrical connector 113 through the through hole 1113 and connecting it to the electrical connection terminal 1112, the part near the end used for electrical connection is wrapped inside the lighting unit 111, effectively dispersing the stress generated by bending or torsion, and avoiding the risk of breakage caused by concentrated stress at the connection point. At the same time, the through hole 1113 structure provides physical restraint and protection for the electrical connector 113, further enhancing the connection strength and environmental resistance. Specifically, when bending stress is applied to the electrical connector 113, the stress is transmitted along the connector 113 and causes it to deform with the lighting device 100, ensuring that the flexibility of the lighting device 100 is not affected. When the stress is transmitted to the contact area between the electrical connector 113 and the perforation 1113, some of the stress is absorbed and dispersed by the body of the lighting unit 111, and the inner wall of the perforation 1113 provides lateral support to the electrical connector 113, thereby weakening or even eliminating the stress peak concentrated at the connection point, effectively suppressing the stress concentration phenomenon near the solder joint, and significantly reducing the risk of fatigue fracture of the wire solder joint.

[0022] To ensure heat dissipation of the LED chip 112, in some embodiments, a heat sink is provided on the side of the lighting unit 111 away from the LED chip 112. This heat sink is insulated from the conductive lines to ensure electrical safety. Since the LED chip 112 generates heat during illumination, heat accumulation will affect its luminous efficiency and lifespan. Therefore, the heat sink at least covers the area where the LED chip 112 is located, helping to improve the overall heat dissipation efficiency of the lighting unit 111 and preventing performance degradation or damage due to overheating. It is understood that the heat sink can be made of materials with high thermal conductivity, such as metal substrates, graphene films, or ceramic materials, to achieve rapid heat conduction. The heat sink and the lighting unit 111 can be fixedly connected by methods including but not limited to thermally conductive adhesive, pressing, or snap-fitting. To further improve heat dissipation, several heat dissipation fins can be added to the heat sink. These fins increase the heat dissipation area, thereby increasing the speed of heat dissipation.

[0023] It is understood that in some embodiments, the through hole 1113 is a through hole penetrating the lighting unit 111, the electrical connection terminal 1112 and the lamp bead 112 are located on the same side of the lighting unit 111, and the electrical connection terminal 1112 is located at the periphery of the through hole 1113. One end of the electrical connector 113 enters the through hole 1113 from the side of the lighting unit 111 away from the lamp bead 112, and extends to the side of the lighting unit 111 facing the lamp bead 112 to be electrically connected to the electrical connection terminal 1112; the other end extends to the outside of the lighting unit 111 to connect to an external power source to achieve electrical conduction. In this design, the electrical connector 113, after passing through the through-hole 1113, connects to the electrical terminal 1112 on the side of the lighting unit 111 opposite to the electrical connector 113. Therefore, when bending stress is applied to the electrical connector 113, the through-hole 1113 structure not only acts as a guide but also disperses stress through multi-point contact, preventing stress from being directly transmitted through the electrical connector 113 to the connection point of the electrical terminal 1112, thus effectively avoiding stress concentration at the connection. Furthermore, since the electrical terminal 1112 is located around the through-hole 1113, it can be positioned and guided during the connection process between the electrical connector 113 and the electrical terminal 1112, improving assembly accuracy and production efficiency.

[0024] In some embodiments, the through hole 1113 can be a blind hole, with the electrical connection terminal 1112 at least partially located at the bottom of the through hole 1113, and one end of the electrical connector 113 inserted into the through hole 1113 from the side of the lighting unit 111 away from the lamp bead 112 and electrically connected to the electrical connection terminal 1112. It is understood that the connection methods between the electrical connector 113 and the electrical connection terminal 1112 include, but are not limited to, conductive adhesive bonding, welding, or elastic pressing. In some embodiments, conductive adhesive can be pre-applied into the through hole 1113, and then one end of the electrical connector 113 can be inserted and cured by heat to form a stable electrical connection between the electrical connector 113 and the electrical connection terminal 1112. In other embodiments, liquid flux and / or solder paste can be pre-injected into the through hole 1113, or a pre-formed solder ring can be placed in the through hole 1113 before inserting the electrical connector 113 and performing reflow soldering to achieve a high-strength electrical connection. In some other embodiments, the electrical connection terminal 1112 may be designed as an elastic contact (e.g., a wire clamping tube structure). When the electrical connection 113 is inserted into the through hole 1113, the elastic contact deforms and tightly covers the end of the electrical connection 113, thereby forming a stable and reliable electrical connection. At the same time, it has a certain stress buffering capacity, which can effectively cope with the problem of connection loosening caused by thermal expansion and contraction or mechanical vibration.

[0025] In some embodiments, the light-emitting component 110 includes a plurality of LEDs 112, which are mounted on the lighting unit 111 and connected in series and / or parallel via conductive lines. To meet high brightness requirements, some of the LEDs 112 are connected in series to ensure voltage adaptability, while others are connected in parallel to increase the total luminous flux. This effectively reduces the operating current of individual LEDs 112, extends their lifespan, and improves the overall brightness performance of the light-emitting component 110.

[0026] Reference Figures 1 to 8 A second aspect of the present invention provides a lighting device 100 that effectively improves the concentration and stability of light illumination. The lighting device 100 includes a housing 160, a flexible base shell 120, a support member 130, and a light-emitting component 110. The housing 160 is a rigid structure and is used to enclose the flexible base shell 120, the support member 130, and the light-emitting component 110. The housing 160 includes a first base plate 162 and first side plates 163 connected to opposite sides of the first base plate 162. The two first side plates 163 and the first base plate 162 together define an installation space 161 with an opening 164 on one side. It is understood that one side of the opening 164 of the housing 160 is opposite to its first base plate 162, and the opening 164 can be used to install and remove the flexible base shell 120 and the light-emitting component 110, etc. It should be noted that the material of the housing 160 can be aluminum alloy, stainless steel, magnesium alloy, titanium alloy, or galvanized steel, etc., and the specific material selection depends on the actual situation.

[0027] Reference Figure 2 and Figure 6 The flexible base shell 120 has an accommodating space 121 extending through its extension direction. Specifically, the accommodating space 121 can extend through the first direction X. The support member 130 and the light-emitting component 110 are both accommodated within the accommodating space 121. The flexible base shell 120 includes a second base plate 122 and second side plates 123 connected to opposite sides of the second base plate 122. The second base plate 122 is configured as a flexible transparent structure to allow light emitted by the light-emitting component 110 to pass through smoothly. The flexible base shell 120 can be made of flexible materials including but not limited to silicone, TPU (thermoplastic polyurethane elastomer), or PVC (polyvinyl chloride) to ensure good bending adaptability and deformation resistance. In some embodiments, the second base plate 122 and the second side plates 123 can be manufactured using an integral molding process to ensure structural continuity and sealing, thereby effectively avoiding gap problems caused by poor splicing or bonding. The integral molding process includes, but is not limited to, injection molding, extrusion molding, or calendering. In other embodiments, the second base plate 122 and the second side plate 123 may also adopt a separate structure and be firmly connected by means of hot welding, solvent bonding, overmolding or secondary injection molding, so as to improve the connection strength and ensure the sealing effect.

[0028] Reference Figures 2 to 6 A support member 130 is installed within the accommodating space 121, and the support member 130 at least partially abuts against the second base plate 122 and the two second side plates 123. In some embodiments, the support member 130 may abut against the entire bottom wall surface of the second base plate 122 facing the accommodating space 121 and the entire side wall surface of the second side plate 123 facing the accommodating space 121. In other embodiments, the support member 130 may abut against a portion of the bottom wall surface of the second base plate 122 facing the accommodating space 121 and a portion of the side wall surface of the second side plate 123 facing the accommodating space 121. The specific assembly configuration of the support member 130 with the second base plate 122 and the second side plate 123 may vary depending on the actual situation. The support member 130 is configured as a flexible support body that can be elastically deformed, ensuring good support performance even when the flexible base shell 120 is bent, without interfering with the bending or torsion of the flexible base shell 120. The support 130 can be made of materials with good resilience, including but not limited to silicone, rubber, TPE (thermoplastic elastomer) or foam materials. Its surface can be provided with positioning grooves that are compatible with the light-emitting component 110 to accurately fix the position of the lamp bead 112 and prevent displacement.

[0029] The light-emitting component 110 consists of multiple lighting units 111 and their electrical connectors 113. Each lighting unit 111 is equipped with at least one LED 112, and these LEDs 112 all face the second base plate 122 to ensure that light can pass through the second base plate 122 uniformly. It is understood that each lighting unit 111 can be equipped with two, three, or more LEDs 112, and the specific number is selected comprehensively based on the lighting requirements, light uniformity requirements, and the bending radius of the lighting device 10. For ease of description, the following explanation uses two LEDs 112 on the lighting unit 111 as an example.

[0030] Reference Figures 6 to 8 The specific assembly configuration of the outer shell 160 and the flexible base shell 120 is described below. In some embodiments, a first side plate 163 of the outer shell 160 has a first protrusion 1631 facing the mounting space 161. Specifically, the first protrusion 1631 can be integrally formed with the outer shell 160 or separately formed. In this embodiment, the first protrusion 1631 is formed by stamping the outer shell 160 as an example. A second side plate 123 of the flexible base shell 120 has a first groove 129 facing the outer side of the first side plate 163. The first protrusion 1631 passes through the first groove 129. That is, the rigid outer shell 160 can stably maintain the flexible base shell 120, the support member 130 and the light-emitting component 110 housed in its mounting space 161 in the target shape, thereby enabling the light-emitting component 110 to stably illuminate the target area, effectively reducing glare, increasing the illuminance of the target area and ensuring the concentration and stability of the illumination.

[0031] Furthermore, this solution, by setting an elastically deformable support member 130 and having it at least partially attached to the second base plate 122 and two second side plates 123 of the flexible base shell 120, and simultaneously placing the light-emitting component 110 on the support member 130 with the LED beads 112 facing the base plate, effectively eliminates the gap between the LED beads and the frame inside traditional flexible wall washer lights. This effectively reduces light scattering loss, allowing light to be emitted more concentratedly and efficiently through the flexible transparent second base plate 122, thereby improving the directivity, light emission efficiency, and optical path stability of the lighting device 100. In addition, the support member 130, as a flexible support body, can elastically deform synchronously with the flexible base shell 120 and effectively absorb bending stress. Combined with the stable constraint provided by the flexible base shell 120, this ensures that the light-emitting component 110 will not shift or loosen during repeated bending of the device, thereby greatly enhancing the lighting device 100's ability to resist bending stress, reducing the risk of LED beads 112 falling off or circuit connection failure, and improving the product's mechanical durability and long-term reliability.

[0032] To improve the stability of the assembly connection between the outer shell 160 and the flexible base shell 120, in some embodiments, each of the first side plates 163 of the outer shell 160 has a first protrusion 1631 facing the mounting space 161, as shown in the figure. Figure 7 In terms of orientation, the first side plate 163 on the left side of the outer shell 160 has a first protrusion 1631 extending towards the right, and the first side plate 163 on the right side of the outer shell 160 has a first protrusion 1631 extending towards the left. Each second side plate 123 of the flexible base shell 120 has a second groove facing the outer side of its corresponding first side plate 163, as shown in the reference... Figure 6 In terms of orientation, the second side plate 123 on the left side of the flexible base shell 120 has a first groove 129 recessed to the right, and the second side plate 123 on the right side of the flexible base shell 120 has a first groove 129 recessed to the left. Each first protrusion 1631 is correspondingly inserted into each first groove 129. That is, the rigid shell 160 can make the support member 130 and the light-emitting component 110 housed in the internal space 121 of the flexible base shell 120 more stably maintain the target shape, thereby enabling the light-emitting component 110 to stably illuminate the target area, effectively reducing glare, further improving the illuminance of the target area, and ensuring the concentration and stability of the illumination.

[0033] It should be noted that in some embodiments, the first side plate 163 of the outer shell 160 is provided with a plurality of first protrusions 1631, and each first protrusion 1631 can be arranged at intervals along the second direction. The interval between two adjacent first protrusions 1631 can be uniform or non-uniform. The second side plate 123 of the flexible base shell 120 is provided with a plurality of first grooves 129, and each first protrusion 1631 can be correspondingly inserted into each first groove 129. This solution can further improve the stability and reliability of the assembly connection between the outer shell 160 and the flexible base shell 120. In other embodiments, the structural dimensions of each first protrusion 1631 can be the same or different, and each first groove 129 can be adapted to accommodate the arrangement of each first protrusion 1631.

[0034] The specific structure of the first base plate 162 of the housing 160 is described below. In some embodiments, the first base plate 162 has a first bottom wall surface 1621 and a second bottom wall surface 1622 facing the mounting space 161, as shown below. Figure 7 In terms of orientation, the bottom wall surface in the middle of the first base plate 162 can be the first bottom wall surface 1621, and the bottom wall surface on the left side of the first base plate 162 can be the second bottom wall surface 1622. Along the axis parallel to the opening 164, refer to... Figure 7The orientation, specifically along the vertical direction, is such that the distance from the first bottom wall surface 1621 to the flexible base shell 120 is greater than the distance from the second bottom wall surface 1622 to the flexible base shell 120. In other words, when the flexible base shell 120 is installed within the installation space 161 of the outer shell 160, a portion of the first bottom plate 162 of the outer shell 160 is spaced from the flexible base shell 120. This design effectively prevents the bottom space of the flexible base shell 120 from becoming too sealed after assembly with the outer shell 160, thus preventing a vacuum from forming and making it difficult to easily assemble and disassemble the outer shell 160 and the flexible base shell 120.

[0035] It should be noted that in some embodiments, a groove may be provided on the side of the first base plate 162 facing the mounting space 161, so that the first base plate 162 is at least partially spaced from the flexible base shell 120. In other embodiments, the first base plate 162 may be partially bent to space from the flexible base shell 120. The specific arrangement of the first base plate 162 may vary depending on the actual situation. This embodiment of the application uses the example of the first base plate 162 having a groove for illustration.

[0036] Reference Figure 7 and Figure 8 The specific structure of the first base plate 162 of the outer casing 160 is described below. In some embodiments, the first base plate 162 is provided with a plurality of partition holes 1623, each partition hole 1623 extending along a direction parallel to the relative arrangement of the two first side plates 163, as shown in the figure. Figure 7 The orientation, that is, each partition hole 1623 can be arranged to extend in the left and right direction. Referring to the extension direction of the outer casing 160... Figure 7 The orientation, that is, along the front-to-back direction, is such that the partition holes 1623 are arranged at intervals. It should be noted that the interval between two adjacent partition holes 1623 can be uniform or non-uniform, and the specific arrangement can be determined according to the actual situation.

[0037] The first base plate 162 of this design allows the rigid outer shell 160 to undergo localized deformation by setting the partition hole 1623, effectively releasing stress and meeting the lighting needs in different directions. In addition, the partition hole 1623 also helps ensure the stability of the lighting unit 111. Specifically, when the outer shell 160 bends, it can first deform at the partition hole 1623, thereby guiding the bending area to concentrate at the partition hole 1623 position, reducing the transmission of bending stress to the lighting unit 111, further protecting the lighting unit 111 from excessive stress, and facilitating the adjustment of the lighting direction according to actual lighting needs, ensuring lighting effect.

[0038] Please see Figure 3 and Figure 6The side of the second side plate 123 facing the accommodating space 121 has a first limiting groove 124 communicating with the accommodating space 121. The first limiting groove 124 has a first wall surface 1241 and a second wall surface 1242 opposite to each other along the second direction Y (parallel to the direction from the light-emitting component 110 to the support member 130). The support member 130 has a first surface 131 and a second surface 132 opposite to each other along the second direction Y. The first surface 131 of the support member 130 abuts against the first wall surface 1241, and the second surface 132 abuts against the second wall surface 1242. The second wall surface 1242 is coplanar with the surface of the second bottom plate 122 facing the accommodating space 121. This design helps the support member 130 to be stably positioned in the accommodating space 121 and avoids the light-emitting component 110 from shifting due to shaking or deformation. Meanwhile, since the first wall surface 1241 can exert a reaction force on the first surface 131 of the support member 130, the support member 130 can maintain a stable position while being compressed and deformed when the outer shell bends. Furthermore, since the second wall surface 1242 is coplanar with the second base plate 122, the support member 130 can always adhere to the second base plate 122, ensuring no gaps are generated between the support member 130 and the second base plate 122, further ensuring that the light-emitting component 110 maintains a stable light-emitting effect during dynamic bending. In addition, compared to the method of using adhesive to fix the light-emitting component 110 in related technologies, this solution avoids the problem of loosening or poor contact of the light-emitting component 110 due to adhesive aging or peeling, significantly improving the long-term reliability and stability of the product.

[0039] In some embodiments, the outer surface of the second base plate 122 or even the surface of the second side plate 123 has an anti-ultraviolet coating to protect internal components from damage caused by prolonged exposure to sunlight, thereby further extending their service life.

[0040] To further ensure the installation stability of the light-emitting component 110 within the flexible housing 120, in some embodiments, please refer to... Figure 3 and Figure 6A second limiting groove 125 communicating with the accommodating space 121 is also provided on the side of the second side plate 123 facing the accommodating space 121. The second limiting groove 125 is arranged at an interval from the first limiting groove 124, and the second limiting groove 125 can be used to lock and clamp the lighting unit 111. This design not only enhances the fixing strength of the lighting unit 111 and reduces the risk of displacement caused by external impact, but also simplifies the assembly process and improves production efficiency. Specifically, the dimension of the second limiting groove 125 along the second direction Y is not greater than the dimension of the lighting unit 111 in the second direction Y, to ensure that the lighting unit 111 is tightly clamped and prevents it from loosening or shifting in the second direction Y. Meanwhile, the groove wall of the second limiting groove 125 can effectively limit the side of the lighting unit 111. Combined with the fixing effect of the first limiting groove 124 on the support member 130, and the bearing and support of the support member 130 on the lighting unit 111, a stable structure with multi-point coordinated fixation is formed, effectively suppressing the displacement or tilting of the lighting unit 111 in complex deformation environments. This structure is particularly suitable for working scenarios with frequent bending or long-term vibration, ensuring that the light output direction and brightness remain consistent, and improving the overall lighting quality and system reliability.

[0041] In some embodiments, a conductive track can be provided inside the second limiting groove 125 to directly power the lighting unit 111, reducing external wiring and making the entire device more concise and aesthetically pleasing. This enhances the product's practicality and provides users with a better experience.

[0042] In order to avoid structural damage or electrical connection failure of the light-emitting component 110 due to excessive twisting during use, in some embodiments, the lighting unit 111 may be made of a rigid PCB substrate, and adjacent lighting units 111 are connected by electrical connectors 113.

[0043] Please see Figure 5The support member 130 includes a main body 133 and a plurality of support portions 134 connected to the main body 133. The two ends of the main body 133 along the third direction Z (perpendicular to the first direction X and the second direction Y) are respectively engaged in the first limiting grooves 124 on the second side plate 123 to ensure the fit between the support member 130 and the second base plate 122, preventing gaps between them, and ensuring the stability of the support member 130 within the accommodating space 121. Each support portion 134 extends from the main body 133 along the second direction Y, and its end abuts against the lighting unit 111, ensuring the stable fixation of the lighting unit 111. Specifically, the support portions 134 and the main body 133 can be manufactured using an integral molding process, including but not limited to injection molding or extrusion molding. The lamp beads 112 are spaced apart from the support portions 134, ensuring effective support for the lighting unit 111 while preventing the support portions 134 from obstructing the lamp beads 112, ensuring unobstructed light output. In addition, the support portion 134 can separate adjacent LED beads 112, ensuring that the light-emitting areas of adjacent LED beads 112 do not interfere with each other, effectively improving the uniformity and clarity of the lighting. In particular, when one of the LED beads 112 malfunctions, the light-shielding and isolation function of the support portion 134 can help maintenance personnel quickly locate the faulty LED bead 112, reducing troubleshooting time.

[0044] To further ensure the effective support of the support member 130 for the light-emitting component 110, in some embodiments, please refer to Figure 5 The lighting unit 111 has a snap-fit ​​groove 1111 on the side facing the support member 130. The end of the support part 134 away from the second base plate 122 is adapted to be inserted into the snap-fit ​​groove 1111, thereby restricting the movement of the lighting unit 111 along the first direction X and the third direction Z. The second limiting groove 125 can restrict the displacement of the lighting unit 111 along the second direction Y, thereby realizing the precise positioning and stable fixation of the lighting unit 111 in three-dimensional space, effectively preventing displacement caused by vibration or thermal expansion and contraction.

[0045] Each lighting unit 111 is supported by at least two support portions 134. This design improves the stability of the lighting unit 111, especially when the device is bent or subjected to external forces, effectively preventing the lighting unit 111 from shifting or being damaged. Even when the flexible base shell 120 bends or twists, as the support member 130 deforms along with the flexible base shell 120, the support portion 134 can push the lighting unit 111 to change its position and orientation while providing support, preventing the lighting unit 111 from disengaging from the second limiting groove 125 and maintaining reliable contact with the electrical connector 113, thereby ensuring circuit continuity and operational stability. The guiding and limiting effect of the support portion 134 on the lighting unit 111 during deformation further reduces the risk of structural loosening due to vibration or bending, and improves the overall assembly durability. In some embodiments, each lighting unit 111 may be supported by three, four, or even more support portions 134 to adapt to more complex installation environments or higher mechanical performance requirements, especially in large-size or high-density lighting scenarios, further enhancing structural rigidity and resistance to deformation, ensuring that the lighting unit 111 maintains precise position and stable light output during long-term operation. For ease of description, the following description uses an example of each lighting unit 111 being supported by four support portions 134. Each lighting unit 111 has two spaced-apart LEDs 112. Two support portions 134 are located on both sides of one LED 112 along the first direction X, and the other two support portions 134 are located on both sides of the other LED 112 along the first direction X, thereby forming independent and separate supports for each LED 112, effectively avoiding thermal interference and optical crosstalk between LEDs 112. This layout ensures structural symmetry while improving the stress balance of the lighting unit 111 during dynamic bending, further suppressing local stress concentration and extending the device's lifespan.

[0046] In some embodiments, the lighting device 100 further includes an encapsulation layer, which is a structure formed by curing a liquid encapsulating material. This encapsulation layer is located on the side of the light-emitting component 110 opposite to the support member 130, and fills the gaps between adjacent light-emitting components 110 and the gaps between the light-emitting component 110 and the flexible base shell 120. Furthermore, the encapsulation layer covers the portion of the support member 130 located between adjacent light-emitting components 110, forming a double-fixing structure for the light-emitting component 110 with the support member 130, effectively suppressing displacement of the light-emitting component 110 during vibration or bending. It is understood that the encapsulation layer can be made of materials including, but not limited to, silicone rubber, flexible polyurethane, or epoxy resin. Thus, the two support portions 134 located on both sides of the lamp bead 112 can also effectively block the flow path of the liquid encapsulating material before curing, preventing it from flowing to the light-emitting surface of the lamp bead 112 during the molding process, thereby avoiding affecting the light extraction efficiency and optical performance.

[0047] To prevent structural stacking of the support member 130 during bending or torsion of the flexible base shell 120, please refer to... Figure 5 In some embodiments, the main body 133 of the support member 130 is provided with a plurality of partition grooves 135 spaced apart along the first direction X. Each partition groove 135 is located between adjacent lighting units 111, and the distance from the bottom of the partition groove 135 to the side of the main body 133 facing the second base plate 122 is less than the thickness of the main body 133 (i.e., the dimension of the main body 133 along the second direction Y). This allows the main body 133 to undergo local deformation along the partition groove 135 when bending, effectively releasing stress and avoiding the normal deformation of the support member 130 due to the bending and stacking of materials. In addition, the partition grooves 135 also help to ensure the stability of the lighting unit 111. Specifically, when the support member 130 bends with the flexible base shell 120, it can first deform at the partition grooves 135, thereby guiding the bending area to concentrate at the partition grooves 135, reducing the transmission of bending stress to the lighting unit 111, and further protecting the lighting unit 111 from excessive stress. It is understandable that the cross-sectional shape of the partition groove 135 on the plane perpendicular to the third direction Z can be arc-shaped, V-shaped, or multi-step.

[0048] Furthermore, the main body 133 may be provided with a reinforcing rib structure between adjacent partition slots 135 to improve the rigidity of the support member 130 in the non-deformation area, thereby ensuring that the lighting unit 111 located in the area can obtain sufficient structural support and maintain its positional accuracy and light output stability in complex deformation environments.

[0049] Please see Figure 5 The support member 130 has multiple light-transmitting holes 136, which are correspondingly arranged with respect to the lamp beads 112 along the second direction Y and penetrate through the first surface 131 and the second surface 132 of the support member 130, thereby allowing the light emitted by the lamp beads 112 to directly pass through the second base plate 122. The design of the light-transmitting holes 136 not only optimizes the light transmission path and reduces light loss, but also improves the overall lighting efficiency. Due to the presence of the light-transmitting holes 136, the light emitted by the lamp beads 112 can directly pass through the support member 130 without passing through other media, which helps to maintain the intensity and uniformity of the light. In some embodiments, the diameter of the light-transmitting holes 136 gradually increases along the direction from the first surface 131 to the second surface 132, further expanding the light emission angle and improving the uniformity of illumination.

[0050] To further improve light utilization and lighting quality, a reflective layer or reflective material can be provided inside or around the light-transmitting hole 136. This way, when light passes through the light-transmitting hole 136, it will be reflected back, increasing light utilization and reducing light loss.

[0051] Reference Figures 2 to 4In some embodiments, the lighting device 100 includes a focusing assembly 150, which guides and concentrates the light emitted by the lamp beads 112. Multiple focusing assemblies 150 can be provided, each corresponding to a specific lamp bead 112. Each focusing assembly 150 includes a focusing element 151 and a diaphragm 152, with the diaphragm 152 covering the focusing element 151. The diaphragm 152 can be positioned between the focusing element 151 and the second base plate 122. The focusing element 151 focuses and guides the light emitted by the lamp beads 112 to the diaphragm 152, and the diaphragm 152 guides the focused light to the second base plate 122 for emission. Thus, the focusing element 151 can initially adjust the light emission angle, and the diaphragm 152 can provide secondary guidance to the light processed by the focusing element 151. Therefore, the focusing assembly 150 can effectively improve the concentration and utilization rate of the light.

[0052] Reference Figures 2 to 5 The specific assembly configuration of the diaphragm 152 is described below. In some embodiments, the diaphragm 152 may be disposed on the side of the support member 130 facing away from the second base plate 122. The support member 130 has a mounting groove 137 on the side facing the focusing member 151, and the diaphragm 152 may be accommodated in the mounting groove 137 and detachably connected to the support member 130. Specifically, the diaphragm 152 may be snapped, screwed, or glued to the support member 130. In other embodiments, the diaphragm 152 may also be disposed on the side of the support member 130 facing the second base plate 122, and the mounting groove 137 may be provided on the side of the support member 130 facing the second base plate 122, and the diaphragm 152 may be accommodated in the mounting groove 137 and detachably connected to the support member 130. This application embodiment takes the diaphragm 152 being disposed on the side of the support member 130 away from the second base plate 122 as an example. This solution can effectively improve the stability of the assembly connection between the diaphragm 152 and the support member 130, and ensure the concentration and reliability of the diaphragm 152 in guiding light.

[0053] It should be noted that in some embodiments, the diaphragm 152 can be made of an optical-grade polymer with high light transmittance, heat resistance, and aging resistance. Specifically, the diaphragm 152 can be made of PMMA (acrylic), PC (polycarbonate), PET (polyethylene terephthalate), or APET (amorphous polyethylene terephthalate), etc. In other embodiments, the structure of the diaphragm 152 can be a microprism array, microlens array, grating structure, diffraction structure, or a diffusion particle hybrid type, etc. The specific structure and material selection of the diaphragm 152 can be determined according to the actual situation.

[0054] Reference Figure 2 and Figure 4The specific configuration of the focusing element 151 is described below. Each focusing element 151 corresponds to each lamp bead 112. Specifically, one end of the focusing element 151 covers the lamp bead 112, and the other end faces the second base plate 122 and covers the light-transmitting hole 136 on the support member 130. The focusing element 151 focuses and guides the light emitted by the lamp bead 112 to the second base plate 122, thereby improving the concentration and utilization of the light. In addition, the tight fit between the focusing element 151, the lamp bead 112, and the light-transmitting hole 136 not only prevents light loss but also protects the lamp bead 112 and extends its service life. In some embodiments, the focusing element 151 can be made of optical-grade plastic or glass material with high light transmittance to ensure efficient light transmission while possessing good heat resistance and anti-aging properties. The inner surface of the focusing element 151 can be further coated to improve reflection efficiency and reduce light energy loss. In other embodiments, the light-concentrating element 151 may adopt a design similar to a lampshade structure, and achieve directional guidance and diffusion control of light through the curvature change of the inner wall, thereby adapting to the lighting needs of different scenarios.

[0055] To facilitate the description and understanding of the relative sizes of the diaphragm 152 and the focusing element 151, a plane perpendicular to the second direction Y is defined as the projection plane. Along the second direction Y, the diaphragm 152 forms a first orthographic projection on the projection plane, which can be a closed geometric shape. Along the second direction Y, the focusing element 151 forms a second orthographic projection on the projection plane, which can also be a closed geometric shape. The area of ​​the second orthographic projection is smaller than the area of ​​the first orthographic projection, and the second orthographic projection falls within the first orthographic projection. That is, when viewed along the second direction Y, the diaphragm 152 can cover the focusing element 151, and the outer dimensions of the diaphragm 152 are larger than the outer dimensions of the focusing element 151. This effectively prevents light from being directly emitted through the second base plate 122 without being guided and focused by the diaphragm 152, effectively improving the stability and reliability of the diaphragm 152 in guiding and focusing light. The specific size ratio between the diaphragm 152 and the focusing element 151 can be determined according to the actual situation.

[0056] The specific structural dimensions of diaphragm 152 are described below. In some embodiments, along the second direction Y, refer to... Figure 3 The orientation, i.e., along the vertical direction, is defined by the thickness H of the diaphragm 152, wherein the diaphragm 152 satisfies the condition: 0.1mm ≤ H ≤ 0.5mm. For example, the thickness of the diaphragm 152 can be 0.1mm, 0.2mm, 0.25mm, 0.3mm, 0.4mm, 0.45mm, or 0.5mm, etc. Preferably, the diaphragm 152 satisfies the condition: 0.2mm ≤ H ≤ 0.3mm, that is, the thickness of the diaphragm 152 can be 0.2mm, 0.25mm, or 0.3mm, etc. The diaphragm 152 in this solution, using the above-mentioned thickness range, can not only produce a significant guiding effect on light, but also minimize luminous flux loss and avoid unnecessary scattering that disrupts the concentration of illumination.

[0057] For easier installation of the support 130 and the light-emitting assembly 110, please refer to [link / reference needed]. Figure 2 In some embodiments, a mounting opening 127 communicating with the receiving space 121 is further formed on the flexible base shell 120. This mounting opening 127 is positioned opposite to the second base plate 122 along the second direction Y, facilitating the insertion of the support member 130 and the light-emitting component 110 into the receiving space 121 through this mounting opening 127. Specifically, when installing the support member 130 and / or the light-emitting component 110, the flexible base shell 120 can deform through the mounting opening 127, causing the receiving space 121 it defines to elastically expand, thereby reducing assembly resistance. After installation, the flexible base shell 120 returns to its initial deformation, ensuring that the support member 130 and the light-emitting component 110 are firmly positioned. The mounting opening 127 not only improves assembly convenience but also effectively avoids component damage caused by forced insertion.

[0058] Therefore, the lighting device 100 also includes a top plate 126. After the light-emitting component 110 is installed in the receiving space 121 and contacts the support member 130 on the side opposite to the second base plate 122, the top plate 126 is installed in the mounting opening 127 to close the receiving space 121. The top plate 126 is designed to match the shape of the mounting opening 127, and the top plate 126 fits tightly with the edge of the mounting opening 127, further enhancing the overall structural integrity, while preventing external dust or moisture from entering the receiving space 121, improving the protection level and long-term reliability of the lighting device 100. The installation of the top plate 126 can be achieved by snapping, bonding, or heat fusion after the light-emitting component 110 is positioned, to ensure a secure enclosure and a neat appearance. In addition, the sealed connection between the top plate 126 and the second side plate 123 can be achieved by one or more processes, including but not limited to ultrasonic welding, hot pressing, or sealant coating, to ensure the reliability of the seal at the connection.

[0059] To further ensure the stability and reliability of the electrical connection of the lighting device 100, the top plate 126 is provided with a through-hole extending into the accommodating space 121. The through-hole is used for power supply lines or signal lines to pass through the accommodating space 121 from the outside and connect to the electrical connection terminals 1112 of the light-emitting component 110, ensuring the stability of the line connection during flexible deformation. An elastic sealing sleeve is provided around the through-hole, which can automatically fit after the line is passed through, preventing gaps caused by bending of the device, thereby avoiding short circuits or poor contact caused by the intrusion of external environmental media.

[0060] In other embodiments, please refer to Figure 2The flexible base shell 120 has a port 128 communicating with the accommodating space 121. This port 128 extends along a first direction X. During the installation of the support member 130 and the light-emitting component 110, the support member 130 and the light-emitting component 110 can be inserted into the accommodating space 121 along the first direction X and guided to a predetermined position through this port 128. Therefore, the lighting device 100 also includes a cover plate 140, and the flexible base shell 120 has a liquid injection hole. After the light-emitting component 110 is installed in the accommodating space 121, the cover plate 140 is installed at the port 128, liquid encapsulation material is injected into the accommodating space 121 through the liquid injection hole, and then cured and sealed. It is understood that for sealing the liquid injection hole, an additional sealing structure can be designed, or the cured encapsulation material can be used to naturally form a sealing layer. This not only enhances the overall protective performance of the lighting device 100 but also effectively prevents moisture and dust intrusion, extending the device's service life. In addition, the liquid injection hole helps to balance the internal and external pressures of the support 130 and the light-emitting component 110 during installation, avoiding assembly difficulties or structural deformation caused by air pressure differences.

[0061] In some embodiments, adhesive can be applied directly through port 128, and then the cover plate 140 can be placed on port 128 to achieve a seal. It is understood that the number of ports 128 can be one or two; the following explanation uses two ports 128 as an example. Please refer to... Figure 2 When the flexible housing 120 has two ports 128 arranged opposite each other along the first direction X, the lighting device 100 also includes two cover plates 140. After the light-emitting component 110 is installed in the receiving space 121, one of the cover plates 140 is installed onto one of the ports 128 to ensure that the port 128 is effectively sealed. This step not only protects the internal components from the influence of the external environment, but also provides the necessary sealing conditions for the subsequent injection of liquid encapsulation material. Next, liquid encapsulation material is injected into the receiving space 121 through the other unsealed port 128 and allowed to solidify to form a stable protective layer. This process ensures that the liquid encapsulation material can be evenly distributed throughout the receiving space 121, thereby providing optimal protection. Finally, the other cover plate 140 is installed onto the remaining port 128 to completely seal the entire receiving space 121. The two ports 128 not only make the liquid injection and sealing process more efficient and convenient, but also effectively reduce the installation air pressure resistance during the installation of the support 130 and the light-emitting component 110, thereby improving assembly efficiency and structural sealing reliability.

[0062] It is understood that the cover plate 140 can achieve a sealed connection with the flexible base shell 120 in various ways, including but not limited to using waterproof tape, sealing strips, or ultrasonic welding, to ensure a reliable sealing effect. In some embodiments, to adapt to different installation requirements, the cover plate 140 can also be designed as a detachable structure, facilitating user maintenance and replacement of internal components.

[0063] A third aspect of the invention also provides a lighting device 10, see [link to relevant documentation]. Figure 1 and Figure 2 The lighting device 10 includes the lighting apparatus 100 described in any of the above embodiments and a mounting assembly 200 for fixing the lighting apparatus 100. The mounting assembly 200 includes at least two mounting brackets 210, through which the lighting apparatus 100 is fixed to a target mounting surface. For ease of description, the lighting apparatus 100 is defined to have a normal state and a bent state. In the normal state, the mounting brackets 210 are spaced apart along a first direction X, and the lighting apparatus 100 remains straight; while in the bent state, the straight-line distance between adjacent mounting brackets 210 changes with the degree of bending of the lighting apparatus 100, thereby allowing the lighting apparatus 100 to be bent and adjusted according to actual needs to adapt to spatial requirements of different shapes and sizes. This design greatly improves the flexibility and applicability of the lighting device 10, achieving ideal lighting effects on both flat walls and curved structures.

[0064] In some embodiments, the mounting bracket 210 is provided with a wire passage for guiding power supply lines or signal lines from inside the lighting device 100 to an external power source or control system, thereby avoiding wear or safety hazards caused by exposed wires.

[0065] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0066] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0067] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
