Description

Technical Field

[0001] The utility model relates to the technical field of lighting devices, in particular to a strip light with 360° light emission. Background Art

[0002] At present, most of the strip light products on the market are composed of a three-layer structure of a strip light housing, a substrate, and surface-mounted lamp beads. Restricted by traditional packaging processes, the lamp beads generally adopt a 120° planar diffusion light-emitting structure, which has significant optical performance defects in specific applications: the lamp beads are fixedly installed on the PCB substrate in a single-sided array manner, and the radiation optical path forms a fixed angle with the extension direction of the housing, resulting in the near-field light being blocked multiple times by adjacent lamp beads, substrate solder joints, and housing structures, forming a "self-shadowing effect", resulting in obvious dark areas in the lighting system. When applied to scenarios requiring 360° omnidirectional lighting, it is necessary to densely arrange the strip lights or cooperate with auxiliary light sources such as downlights and spotlights for supplementary lighting, which greatly increases energy consumption and installation costs, restricting the lighting effect and design flexibility of large-space scenarios. Summary of the Utility Model

[0003] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a strip light with 360° light emission to solve the problem that the traditional strip light emits light at 120° and cannot meet the use requirements of 360° omnidirectional lighting scenarios.

[0004] The technical solution adopted by the utility model to solve its problems is that the embodiment of the utility model discloses a strip light with 360° light emission, including a long strip-shaped light housing and two long strip-shaped substrates. Opposite light-refracting structures are provided on the inner wall of the light housing. The two substrates are arranged back-to-back in the light housing. The front surfaces of the two substrates are respectively oriented towards the two light-refracting structures and are provided with lamp beads. The lamp beads on each substrate emit light at 120° towards the light housing.

[0007] As an optional implementation manner, in the embodiment of the utility model, the connection between adjacent two light-refracting surfaces is arc-shaped, and its radius of curvature is 0.2 mm.

[0008] As an alternative embodiment, in the embodiment of the present utility model, two opposite limiting grooves are further provided on the inner wall of the light strip housing, one side of the two substrates is located in one of the limiting grooves, and the other side of the two substrates is located in the other limiting groove.

[0009] As an alternative embodiment, in the embodiment of the present utility model, two opposite avoidance grooves are further provided on the inner wall of the light strip housing. The two avoidance grooves are respectively used to avoid the lamp beads on the two substrates, and the two light refracting structures are respectively located in the two avoidance grooves.

[0010] As an alternative embodiment, in the embodiment of the present utility model, the light strip housing includes a light guiding layer and a light diffusing layer.

[0011] As an alternative embodiment, in the embodiment of the present utility model, the light strip housing further includes a limiting structure.

[0012] As an alternative embodiment, in the embodiment of the present utility model, the limiting structure includes a second V-shaped groove provided on the outer surface of the light guiding layer and a third V-shaped groove provided on the inner surface of the light diffusing layer. The second V-shaped groove and the third V-shaped groove are mutually engaged.

[0013] As an alternative embodiment, in the embodiment of the present utility model, the 360° light-emitting light strip further includes a first end cap and a second end cap having a wire. The first end cap seals the first end of the light strip housing, and the second end cap seals the other end of the light strip housing and the wire is electrically connected to the substrate.

[0014] Implementing the embodiment of the present utility model will have the following beneficial effects:

[0015] The utility model provides a 360° light-emitting light strip which includes a strip-shaped light strip housing and two strip-shaped substrates. The inner wall of the light strip housing is provided with two opposite light-refracting structures. The two substrates are arranged back to back in the light strip housing.

[0029] The technical solution of the present utility model will be further described below in conjunction with embodiments and drawings.

[0030] Please refer to Figures 1 to 5 , an embodiment of the present utility model discloses a 360° light-emitting light strip. The 360° light-emitting light strip includes a long strip light strip housing 1 and two long strip substrates 2. Opposite two light-refracting structures are provided on the inner wall of the light strip housing 1. The two substrates 2 are arranged back-to-back in the light strip housing 1. The front surfaces of the two substrates 2 are respectively arranged towards the two light-refracting structures and are provided with lamp beads 21. The lamp beads 21 on each substrate 2 emit light towards the light strip housing 1 at an angle of 120°. The light-refracting structure is used to refract the light emitted by the lamp beads 21, so that the light strip housing 1 emits light at 360°. With such a design method, through the synergistic effect of the double substrates 2 arranged back-to-back and the light-refracting structure, the traditional single-sided light-emitting limitation is broken through: the lamp beads 21 of the two substrates 2 respectively perform symmetric refraction compensation on the 120° light source through the light-refracting structure, which not only eliminates the light self-shadowing effect of adjacent lamp beads 21, but also realizes the two-way extension of the light path; the double light-refracting structure precisely controls the light refraction angle, so that the originally single-sided 120° light emission forms a 360° annular light field without dark areas after refraction, and the light efficiency utilization rate is improved; at the same time, the back-to-back substrate 2 structure, without increasing the volume of the light strip, replaces the traditional multi-light strip superposition scheme through a three-dimensional light distribution design, reduces energy consumption and installation costs, and significantly improves the omnidirectional lighting uniformity and design freedom in large space scenarios.

[0031] In some embodiments, the light-refracting structure includes a plurality of adjacent first V-shaped grooves 111. Two light-refracting surfaces 1111 are formed in the first V-shaped grooves 111. The light-refracting surfaces 1111 are used to refract the light emitted by the lamp beads 21. With such a design method, the light-refracting structure of the first V-shaped grooves 111 significantly improves the light efficiency through the cooperative light distribution of the double light-refracting surfaces 1111: each pair of V-shaped light-refracting surfaces 1111 performs two-way refraction compensation on the 120° light beam of the lamp beads 21 at a symmetric angle, so that the single-sided incident light diffuses after two refractions to increase the light-emitting range, and the adjacent first V-shaped grooves 111 are seamlessly connected to form a continuous refraction interface, integrating the multi-directional scattered light into a 360° annular light field.

[0032] Furthermore, the included angle between the two light-refracting surfaces 1111 is α, and 70° ≤ α ≤ 90°. With such a design method, the cooperative refraction of 70° ≤ α ≤ 90° converts the direct light into a medium beam angle, eliminates the glaring light spot and forms a soft transition light area, meeting the visual comfort requirements of commercial and household scenarios.

[0033] Furthermore, the connection part between two adjacent light-refracting surfaces 1111 is arc-shaped, and its curvature radius is 0.2 mm. With such a design method, the stress dispersion characteristic improves the bending strength of the light strip housing 1 and avoids the risk of brittle fracture.

[0034] In some embodiments, two opposite limiting grooves 112 are further provided on the inner wall of the light strip housing 1. One side of the two substrates 2 is located in one of the limiting grooves 112, and the other side of the two substrates 2 is located in the other limiting groove 112. With such an arrangement, one of the limiting grooves 112 can limit one side of the substrate 2, and the other limiting groove 112 can limit the other side of the substrate 2, thereby defining the position of the substrate 2 in the light strip housing 1.

[0035] In some embodiments, two opposite avoidance grooves 113 are further provided on the inner wall of the light strip housing 1. The two avoidance grooves 113 are respectively used to avoid the lamp beads 21 on the two substrates 2, and the two light refracting structures are respectively located in the two avoidance grooves 113.

[0036] In some embodiments, the light strip housing 1 includes a light guiding layer 11 and a light diffusing layer 12. The light diffusing layer 12 is sleeved outside the light guiding layer 11. Refracting structures are provided on both opposite sides inside the light guiding layer 11, and the two substrates 2 are both located inside the light guiding layer 11. With such a design, the composite structure of the light guiding layer 11 and the light diffusing layer 12 optimizes the light effect through synergy: the light guiding layer 11 is formed of a material with a high light transmittance to form a total reflection channel, which can efficiently conduct the direct light of the lamp beads 21 to the circumferential direction of the housing, avoiding local light intensity overload; the outer light diffusing layer 12 performs multi-directional scattering on the conducted light, eliminating glare and harsh light spots, improving the 360° light output uniformity, and at the same time reducing the light flux loss. While maintaining a high brightness output, this design achieves a soft diffused effect, meeting both the functional requirements of large-area shadowless lighting and the visual comfort requirements of commercial and home scenarios.

[0037] Preferably, both the light guiding layer 11 and the light diffusing layer 12 are white transparent colloids, which can improve the light output efficiency.

[0038] Furthermore, in order to prevent the relative rotation of the light diffusing layer 12 and the light guiding layer 11 from affecting the light emitting effect, the light strip housing 1 further includes a limiting structure, which is provided between the light guiding layer 11 and the light diffusing layer 12 to limit the relative positions of the light guiding layer 11 and the light diffusing layer 12.

[0039] Specifically, the limiting structure includes a second V-shaped groove 114 provided on the outer surface of the light guiding layer 11 and a third V-shaped groove 121 provided on the inner surface of the light diffusing layer 12. The second V-shaped groove 114 and the third V-shaped groove 121 are mutually engaged to define the relative positions of the light guiding layer 11 and the light diffusing layer 12.

[0040] In some embodiments, the 360° light-emitting light strip further includes a first end cap 3 and a second end cap 4 having a wire 41. The first end cap 3 seals the first end of the light strip housing 1, and the second end cap 4 seals the other end of the light strip housing 1 and the wire 41 is electrically connected to the substrate 2.

[0041] A strip light capable of 360° light emission provided by the present utility model comprises a long strip-shaped light strip housing 1 and two long strip-shaped substrates 2. Two refractive structures are provided on the inner wall of the light strip housing 1 oppositely. The two substrates 2 are arranged back to back in the light strip housing 1. The front surfaces of the two substrates 2 face the two refractive structures respectively and are provided with lamp beads 21. The lamp beads 21 on each substrate 2 emit light towards the light strip housing 1 at an angle of 120°. The refractive structures are used to refract the light emitted by the lamp beads 21 so that the light strip housing 1 emits light at 360°. With such a design method, through the synergistic effect of the double substrates 2 arranged back to back and the refractive structures, the limitation of traditional single-sided light emission is broken through: the lamp beads 21 on the two substrates 2 respectively perform symmetric refraction compensation on the 120° light source through the refractive structures, which not only eliminates the light self-shielding effect of adjacent lamp beads 21, but also realizes the two-way extension of the light path; the double refractive structures accurately control the light refraction angle, so that the originally single-sided 120° light emission forms a 360° annular light field without dark areas after refraction, and the light efficiency utilization rate is improved; at the same time, the back-to-back substrate 2 structure, without increasing the volume of the light strip, replaces the traditional multi-light strip superposition scheme through a three-dimensional light distribution design, reduces energy consumption and installation costs, and significantly improves the omnidirectional illumination uniformity and design freedom in large space scenarios.

[0042] The above has introduced in detail a strip light capable of 360° light emission disclosed in the embodiments of the present utility model. In this article, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand a strip light capable of 360° light emission of the present utility model and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
