Description

Technical Field

[0001] The utility model belongs to the technical field of lighting lamp strips, and in particular relates to a flexible 360-degree luminous lamp strip that is easy to shape. Background Art

[0002] Flexible light strips, also known as silicone light strips or neon light strips, are generally made of LED lamp beads, FPCB soft boards, conductive metal wires, and flexible plastic or silicone light diffusers. Therefore, they have a certain degree of bendability and can achieve linear lighting arranged in straight or curved forms. They are widely used in indoor ceilings, building edges, urban lighting, landscape lighting, and other places that require linear lighting to achieve lighting edges and beautification effects.

[0003] Existing flexible light strips, such as the one disclosed in Chinese Patent Publication No. CN216113510U and the flexible LED SMD light strip disclosed in Chinese Patent Publication No. CN102095118B, have a structural feature in which the LED beads in the light strip are mounted on a flexible printed circuit board (FPCB). This leads to a large bending range on the front and back sides of the FPCB, making the light strip too flexible and difficult to shape. During installation, a large number of snap-on components are required to secure the light strip. However, the light strip is difficult to bend on the left and right sides of the FPCB. Forced lateral bending can easily cause the FPCB to break, further limiting the bending direction of the light strip. Furthermore, the effective beam angle of the LED beads combined with the light expander is typically 180 degrees or 270 degrees. The beam direction and the bending direction of the light strip are essentially in the same plane, limiting the beam angle. Furthermore, because the conductive wire is located behind the LED beads, the back side of the light strip is shadowed by the conductive wire.

[0004] Therefore, during the installation of the light strip, in order to avoid damage to the light strip and incorrect lighting direction, the installer needs to fully consider the light-emitting angle and bending direction of the light strip before designing the shape and layout of the light strip. This greatly limits the shape and layout design of the light strip, making it difficult to achieve richer and more beautiful artistic shapes. It is not suitable for occasions that require high complexity in the shape of the light strip. Utility Model Content

[0005] In order to solve or partially solve the problems existing in the related art, the utility model provides a flexible 360-degree luminous light strip that is easy to shape. It can achieve 360-degree lighting of the light strip and eliminate the shadows caused by the retaining parts blocking the light. It effectively reduces the limitations of the existing flexible light strips on the shape and layout design due to the difficulty of bending on the left and right sides of the FPCB soft board and the limited lighting angle.

[0006] The present application provides a flexible light strip that is easy to shape, including a light-transmitting body, an FPCB, LED lamp beads, a retaining member, and a light expander. The light-transmitting body is an integrally molded, light-transmitting strip structure. The light-transmitting body has a cavity along its length. The FPCB is disposed in the cavity, and at least one LED lamp bead is mounted on the FPCB.

[0007] Two retaining members are symmetrically embedded inside the two sides of the side wall of the light-transmitting body facing the LED lamp beads. The retaining members are the same length as the light-transmitting body. The two ends of the FPCB are electrically connected to the retaining members through a wire respectively.

[0008] The light expander is an integrally formed cylindrical strip structure that can transmit and diffuse light. The light-transmitting body and the wire are wrapped inside the light expander. The cross-sectional area of ​​the light expander on the front side of the LED lamp bead is larger than the cross-sectional area on the back side of the LED lamp bead.

[0009] The retaining member can support the plastic deformation of the light-transmitting body and the light-expanding body.

[0010] In an optional solution, the light expander is divided into an installation area and a diffusion area by the plane where its axis is located, the light-transmitting body and the wire are wrapped in the installation area, and the LED lamp beads face the diffusion area.

[0011] In an optional solution, multiple FPCBs are arranged in an array along the length of the light-transmitting body in the cavity, and both ends of each FPCB are electrically connected to the retaining member through a wire, and the wire is not within the gap between two adjacent FPCBs.

[0012] In an optional solution, the width of the cavity matches the width of the FPCB, an opening is configured on a side wall of the light-transmitting body facing away from the retaining member, and the light-expanding body is configured with a support portion extending into the opening.

[0013] Beneficial effects of the utility model:

[0014] The utility model arranges the light-transmitting body and the conducting wire in the installation area of ​​the light-expanding body so that the cross-sectional area of ​​the light-expanding body on the front side of the LED lamp bead is larger than the cross-sectional area on the back side of the LED lamp bead, so as to refract and diffuse the light emitted by the LED lamp bead through the diffusion area of ​​the light-expanding body, thereby realizing 360-degree lighting of the light strip and eliminating the shadow caused by the light blocking by the retaining member. By adopting a retaining member that can support the plastic deformation of the light-transmitting body and the light-expanding body as a conductive metal wire for supplying power to the FPCB soft board, the shapeability of the light strip is effectively improved, so that the light strip only needs to pay attention to the bendable direction of the light strip during the shaping and installation process, effectively reducing the limitations of the existing flexible light strip on the shape and layout design of the light strip due to the difficulty in bending in the left and right side directions of the FPCB soft board and the limited light-emitting angle, facilitating the realization of richer and more beautiful artistic shape of the light strip, and being able to adapt to occasions with high requirements on the complexity of the light strip shape. It is easy to install and saves time and effort.

[0024] In this application, the terms "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0025] Due to the structural characteristics of the existing flexible light strips in which the LED lamp beads are installed on the FPCB soft board, the light strips are too flexible on the front and back directions of the FPCB soft board and are not easy to shape, and are not easy to bend on the left and right sides of the FPCB soft board. In addition, the light-emitting angle is limited, and there will be shadows on the back of the light-emitting direction. Therefore, the existing flexible light strips have the problem of requiring full consideration of the light-emitting angle and bending direction of the light strips during installation, which has great limitations on the shape and layout design of the light strips. It is difficult to achieve richer and more beautiful artistic shapes, and they are not suitable for occasions that require high complexity in the shape of the light strips.

[0026] In response to the above problems, the present application makes improvements and innovations and proposes the following embodiments.

[0027] In one embodiment, see Figures 1-4, provides a flexible 360-degree luminous light strip that is easy to shape, including a translucent body 1, an FPCB soft board 2, LED lamp beads 3, a holder 4, and a light expander 5, wherein the translucent body 1 is an integrally molded and light-transmissive strip structure, the translucent body 1 is constructed with a cavity 101 along its length, the FPCB soft board 2 is arranged in the cavity 101, and at least one LED lamp bead 3 is mounted on the FPCB soft board 2, two holders 4 are symmetrically buried on both sides of the side wall of the translucent body 1 facing the LED lamp bead 3, and the holders 4 are the same length as the translucent body 1, and the two ends of the FPCB soft board 2 are electrically connected to the holder 4 through a wire respectively, wherein the wire is not shown in the figure.

[0028] Specifically, the two retaining members 4 are conductive metal wires, which are electrically connected to an external power supply. The FPCB soft board 2 is connected to the retaining members 4 through wires to form a loop, thereby powering the LED lamp beads 3 on the FPCB soft board 2, and then making the LED lamp beads 3 emit light to achieve lighting.

[0029] The light expander 5 is an integrally formed cylindrical strip structure that is translucent and light-scattering. The light translucent body 1 and the wire are wrapped in the light expander 5, wherein the light translucent body 1 is a transparent, light-transmitting flexible PVC plastic or silicone, and the light expander 5 is a milky white, light-transmitting flexible PVC plastic or silicone mixed with a light diffuser. The light translucent body 1 and the light expander 5 are both made by an integral extrusion molding process, so that the light translucent body 1 and the wire can be fully sealed by the light expander 5 to facilitate dust and water prevention, and at the same time, the light expander 5 has good diffusion performance for the light emitted by the LED lamp beads 3.

[0030] In this embodiment, the cross-sectional area of ​​the light expander 5 located on the front side of the LED lamp bead 3 is larger than the cross-sectional area located on the back side of the LED lamp bead 3; specifically, the light expander 5 is divided into an installation area 501 and a diffusion area 502 by the plane where its axis is located. The light-transmitting body 1 and the wire are covered in the installation area 501, and the LED lamp bead 3 is opposite to the diffusion area 502, and no components are set in the diffusion area 502.

[0031] Therefore, by arranging the light-transmitting body 1 and the wire in the mounting area 501 of the light-expanding body 5, and making the outer surface of the light-expanding body 5 cylindrical, the LED lamp bead 3 is directly opposite the diffusion area 502, so that the light emitted by the LED lamp bead 3 can be fully refracted and diffused by the diffusion area 502 of the light-expanding body 5, so that the light emitted by the LED lamp bead 3 is diffused to the area of ​​the mounting area 501 located at the back of the LED lamp bead 3 under the refraction effect of the diffusion area 502, so that the light emitted by the LED lamp bead 3 is evenly distributed 360 degrees from the cylindrical surface of the light-expanding body 5. At the same time, by arranging the two retaining members 4 in the light-transmitting body 1 symmetrically on the two sides of the installation area 501 of the light-expanding body 5 in front of the light-emitting direction of the LED lamp beads 3, the light emitted by the LED lamp beads 3 can be refracted and diffused by the diffusion area 502 of the light-expanding body 5, thereby avoiding the two retaining members 4 from blocking the light emitted by the LED lamp beads 3, and effectively reducing the limitations of the left and right side directions of the FPCB soft board 2 on the shape and layout design of the light strip due to the difficulty in bending and the limited light-emitting angle.

[0032] In this embodiment, the retaining member 4 can support the plastic deformation of the light-transmitting body 1 and the light-expanding body 5. Specifically, the retaining member 4 is a conductive metal wire that is strong enough to support the light strip to maintain its shape after bending, so that the light strip can have a large bending degree in the front and back directions of the FPCB soft board 2. At the same time, the plastic deformation ability of the light strip is achieved by increasing the strength of the retaining member 4, which effectively improves the shapeability of the light strip, so that the light strip can be straightened or bent, thereby facilitating the light strip to achieve rich artistic shapes. At the same time, it can effectively reduce the use of snap-on components for fixing the light strip during installation.

[0033] In this way, by arranging the translucent body 1 and the wire in the installation area 501 of the light expander 5, the cross-sectional area of ​​the light expander 5 on the front side of the LED lamp bead 3 is larger than the cross-sectional area on the back side of the LED lamp bead 3, so that the light emitted by the LED lamp bead 3 is refracted and diffused by the diffusion area 502 of the light expander 5, the 360-degree lighting of the light strip is realized and the shadow caused by the light blocking by the retaining member 4 is eliminated. By adopting the retaining member 4 that can support the plastic deformation of the translucent body 1 and the light expander 5 as the conductive metal wire for supplying power to the FPCB soft board 2, the shapeability of the light strip is effectively improved, so that the light strip only needs to pay attention to the bendable direction of the light strip during the shaping and installation process, effectively reducing the limitations of the existing flexible light strip on the shape and layout design of the light strip due to the fact that it is not easy to bend in the left and right side directions of the FPCB soft board 2 and the luminous angle is limited, making it easy to achieve a richer and more beautiful artistic shape of the light strip, and can adapt to occasions with high requirements on the complexity of the light strip shape. It is easy to install and saves time and effort.

[0034] In some embodiments, multiple FPCBs 2 are arranged in an array along the length of the light-transmitting body 1 in the cavity 101. Each FPCB 2 is electrically connected to the retaining member 4 at both ends via a wire, and the wires are not within the gap between two adjacent FPCBs 2. In this way, the light strip is composed of multiple FPCBs 2 connected in parallel. Each FPCB 2 is arranged at intervals, and each FPCB 2 is independently electrically connected to the retaining member 4 via the wires at its ends. This facilitates cutting the light strip at the gap between two adjacent FPCBs 2 for use in sections as needed during installation. Furthermore, by connecting the FPCBs 2 in parallel, the brightness of the light strip is ensured to be substantially consistent at both ends when the light strip is long.

[0035] In some embodiments, the width of the cavity 101 matches the width of the FPCB soft board 2, and an opening 102 is constructed on the side wall of the light-transmitting body 1 facing away from the retaining member 4, so that the FPCB soft board 2 can be loaded into the cavity 101 through the opening 102 on the light-transmitting body 1 during the production process of the light strip; the light-expanding body 5 is constructed with a support portion 503 extending into the opening 102, so that the opening 102 on the light-transmitting body 1 can be supported by the support portion 503, thereby supporting the light-transmitting body 1 and the cavity 101 from being deformed when the light-transmitting body 1 is squeezed in the radial direction, thereby ensuring that the FPCB soft board 2 is stably installed in the cavity 101.

[0036] Finally, it should be noted that although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can make changes, modifications, replacements and variations to the above embodiments within the scope of the present invention, which should all be included in the scope of protection of this application.
