[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs; the terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit the present application; the specification, claims and above-mentioned drawing description of the present application and their any variants, are intended to cover non-exclusive inclusion. The specification, claims or above-mentioned drawings of the present application or the terms "first", "second" and the like are used to distinguish different objects, not to describe a specific order.

[0034] ​In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0036] refer to Figures 1-6 As shown in the first aspect of the present invention, an LED light strip 1 is provided, which includes: a light-shielding member 11, a light plate 12, and a plurality of LED beads 13; the light-shielding member 11 is elongated and has an inner cavity that extends along the length of the light-shielding member 11; the light plate 12 is disposed in the inner cavity and extends along the length of the light-shielding member 11; a plurality of LED beads 13 are disposed on the surface of the light plate 12 and are spaced apart along the length of the light plate 12; wherein, the light-shielding member 11 is further provided with a relief groove 14, which is formed on the cavity wall of the inner cavity and is used to provide a deformation allowance for the light plate 12 when the LED light strip 1 is bent.

[0037] In this embodiment, by creating a clearance groove 14 on the inner surface of the light-shielding member 11, a certain preset gap is created between the light plate 12 and the light-shielding member 11. This provides a certain deformation accommodation space for the deformation of the light plate 12 during the bending of the light strip 1, avoiding the unexpected deformation of the relatively rigid light plate 12 when the light strip 1 is bent. This prevents stress concentration at one point due to the obstruction of the solid light-shielding member 11, which could cause local bulging or swelling of the light-shielding member 11. At the same time, it also reduces the risk of the light plate 12 breaking due to the restraint of the outer light-shielding member 11 on the light plate 12, thus improving the durability of the product.

[0038] Specifically, the light panel 12 is an FPC board, and the light shield 11 is made of silicone; the LED light strip 1 can be controlled to multiple colors via RGB, DMX-RGBW, etc.

[0039] Specifically, the cross-sectional shape of the light-shielding component 11 is a U-shape with an opening at the top. This ensures that the light strip 1 emits light in a directional manner, reducing light leakage and light pollution.

[0040] Specifically, the lamp strip 1 further comprises a protective layer, a light guide member and a diffusion member, the protective layer is arranged between the light plate 12 and the light shielding member 11 and adheres to the surface of the light plate 12, the light guide member covers the surface of the lamp bead 13, and the diffusion member is arranged above the light guide member. The light guide member and the diffusion member are transparent or translucent solid silica gel, which is used to convert the point light source emitted by the lamp bead 13 into a uniform surface light source and further scatter the light, eliminate the bright spot at the lamp bead 13, and realize the high uniformity of the light in the length direction of the lamp strip 1; the material of the protective layer can be one of FPC, PET and fiber cloth.

[0041] The light shielding member 11, the light guide member and the diffusion member are integrally extruded, and a gap is arranged between the light guide member and the lamp bead 13, and the material thereof can be silica gel, polyurethane, polyvinyl chloride or the like. The integrally extruded structure of the lamp strip 1 eliminates the gaps, tolerance accumulation and potential falling risk caused by traditional multi-component assembly, significantly improves the waterproof and dustproof level, structural strength and durability of the product; the gap with a certain depth between the light guide member and the lamp bead 13 can not only provide space for the expansion and contraction of the light shielding member 11 without direct extrusion, but also reduce the deformation of the lamp strip 1 caused by internal stress; at the same time, the heat generated by the lamp bead 13 during use can be dissipated in the gap, thereby reducing the deformation of the lamp strip 1 during use.

[0042] In one embodiment, the cavity wall of the inner cavity comprises a bottom wall 113, and a first side wall 111 and a second side wall 112 symmetrically arranged on both sides of the bottom wall 113; wherein the accommodation slot 14 is provided with a plurality of accommodation slots 14, and the plurality of accommodation slots 14 are arranged on at least one of the bottom wall 113, the first side wall 111 and the second side wall 112.

[0043] The number and position of the accommodation slot 14 can be customized according to the actual use scene and demand of the LED lamp strip 1 to meet the requirements of side bending or straight bending, different bending directions and different bending degrees of the lamp strip 1 during use.

[0044] Specifically, the lamp bead 13 is arranged on the surface of the cooperation part of the light plate 12 and the bottom wall 113.

[0045] In one embodiment, the plurality of accommodation slots 14 are symmetrically distributed about the axis of the LED lamp strip 1.

[0046] In this embodiment, the accommodation slots 14 are symmetrically distributed along the axis in the width direction of the cross section of the light plate 12, which can guide the lamp strip 1 to uniformly and symmetrically deform around the axis during bending, prevent one-sided overstretching or compression, and avoid the distortion of the lamp strip 1 caused by asymmetry, thereby ensuring the flatness of the lamp strip 1 after bending.

[0047] In one embodiment, the plurality of displacement grooves 14 extend along the length direction of the light shield 11, or the plurality of displacement grooves 14 are arranged at an angle with the length direction of the light shield 11.

[0048] In this embodiment, the plurality of displacement grooves 14 extending along the length direction of the light shield 11 can provide the lamp panel 12 with deformation allowance space in the full length direction, forming comprehensive protection; the plurality of displacement grooves 14 arranged at an angle with the length direction of the light shield 11 can guide the deformation direction of the lamp panel 12 on the basis of providing deformation allowance space, forming more regular distortion, and ensuring the smoothness of the curved lines of the light strip 1.

[0049] In one embodiment, the plurality of displacement grooves 14 are spaced apart on the first side wall 111 in a direction away from the bottom wall 113, the plurality of displacement grooves 14 are spaced apart on the second side wall 112 in a direction away from the bottom wall 113, and / or the plurality of displacement grooves 14 are spaced apart on the bottom wall 113 from the first side wall 111 to the second side wall 112.

[0050] In this embodiment, the plurality of spaced-apart displacement grooves 14 ensure the contact area of the light shield 11 and the lamp panel 12, thereby maintaining the stability of the lamp panel 12 in the light strip 1. Meanwhile, compared with the displacement grooves 14 arranged continuously, the plurality of spaced-apart displacement grooves 14 can further guide the lamp panel 12 without causing the lamp panel 12 to deform at any position and affecting the flatness of the light strip 1.

[0051] In one embodiment, the cross-sectional shapes of the plurality of displacement grooves 14 are the same or different.

[0052] The cross-sectional shapes of the plurality of displacement grooves 14 can be adjusted according to the actual use scene and requirements of the light strip 1 to meet the requirements of side bending or positive bending, different bending directions, and different bending degrees in use of the light strip 1.

[0053] In one embodiment, the cross-sectional shapes of the plurality of displacement grooves 14 include one or more of L-shaped, triangular, quadrilateral, and U-shaped.

[0054] In this embodiment, the L-shaped displacement grooves 14 can better match the edge profile of the lamp panel 12 and provide more stable lateral limiting; the rectangular displacement grooves 14 have simple processing technology and regular buffer space; the trapezoidal displacement grooves 14 can reduce stress concentration of the groove opening while ensuring the buffer depth, thereby enhancing the structural strength of the light shield 11; the triangular displacement grooves 14 have smaller opening volume while meeting the multi-point bending buffer function, and the light strip 1 has higher strength and service life.

[0055] Specifically, the combination of various cross-sectional shapes of the accommodation grooves 14 can better adapt to the shape features of the lamp panel 12, so that the unexpected deformation of the lamp panel 12 at each position is more effectively buffered.

[0056] Reference Figure 6 In one embodiment, the accommodation grooves 14 include first grooves and second grooves, the first grooves are in a strip shape and are arranged on the first side wall 111 and the second side wall 112 respectively, and the second grooves are in a U shape and include a first part formed on the first side wall 111, a second part formed on the second side wall 112, and a third part formed on the bottom wall 113.

[0057] The accommodation grooves 14 form a semi-enclosed cavity at the connection between the first side wall 111, the second side wall 112, and the bottom wall 113, which provides sufficient accommodation space for the stress deformation at the corner of the lamp panel 12, reduces the generation of unexpected deformation, and reduces the possibility of the lamp panel 12 being broken due to stress concentration in the deformation.

[0058] In one embodiment, the cross-sectional shape of the lamp panel 12 is in a U shape. The LED lamp strip 1 contains precise components such as LED lamp beads 13 and circuits, which need to resist physical extrusion, friction, or external force impact. The U-shaped lamp panel 12 can cover the bottom and both sides of the lamp strip 1 at the same time, forming comprehensive protection, compared with the flat panel covering only one side, which can more effectively avoid the stress concentration when the edge is knocked or curled, and reduce the risk of damage to the internal circuit or lamp beads 13.

[0059] In one embodiment, the lamp panel 12 and the inner cavity surface of the light shielding piece 11 are in interference fit.

[0060] In this embodiment, the design of interference fit can make the lamp panel 12 firmly clamped or tightly fitted in the inner cavity of the light shielding piece 11, which can effectively prevent the lamp panel 12 from loosening or displacing inside the lamp strip 1, and also guide the bending point of the lamp panel 12 to slide to the accommodation groove 14, so that the accommodation groove 14 is more effective, and the effect of keeping the lamp strip 1 flat is achieved.

[0061] The above disclosure is only the preferred embodiment of the utility model, of course, cannot limit the scope of the utility model, therefore, the equivalent changes made according to the utility model claims still belong to the scope covered by the utility model.
