[0054] Example 1

[0055] like Figures 1 to 4 As shown, this embodiment provides a light strip that facilitates light distribution, including a light-shielding shell 1 and a first light-transmitting body 2. The light-shielding shell 1 and the first light-transmitting body 2 enclose a first cavity 11. The first light-transmitting body 2 includes a first incident surface 21, a first exit surface 22 and a reflective surface. The first incident surface 21 faces the first cavity 11.

[0056] The light-shielding housing 1 can be made of an opaque material to reduce light leakage in other directions and reduce the impact of light leakage on the overall light output effect of the lamp. The light-shielding housing 1 can be a semi-enclosed structure, such as having a C-shaped or U-shaped cross-section. The first light-transmitting body 2 can be installed at the opening of the light-shielding housing 1 so that the first light-transmitting body 2 and the light-shielding housing 1 can enclose and form a first cavity 11.

[0057] The first light-transmitting body 2 can be made of a light-transmitting material, and when light passes through the first light-transmitting body 2, the first light-transmitting body 2 can adjust the light to achieve light distribution. The adjustment of the light can include changing its light distribution angle and polarization, etc. For example, the first light-transmitting body 2 can be a concave lens, a convex lens, or a lens with a polarizing effect, etc.

[0058] The first light-transmitting body 2 has a first incident surface 21, a first exit surface 22 and a reflective surface. The reflective surface is located between the first incident surface 21 and the first exit surface 22. The reflective surface can reflect part of the light entering from the first incident surface 21, so that part of the light can be emitted from the first exit surface 22, thereby improving the utilization rate of light by the first light-transmitting body 2.

[0059] The first incident surface 21 is configured to face the first cavity 11; in a preferred embodiment, the light source 4 is installed in the first cavity 11 with its emitting surface facing the first incident surface 21, so that most of the light emitted by the light source 4 can enter the first light-transmitting body 2 from the first incident surface 21.

[0060] In terms of spatial structure, both the light-shielding shell 1 and the first light-transmitting body 2 can be strip-shaped structures to form a strip of light. In this embodiment, the length direction of the first light-transmitting body 2 is defined as the first direction. The first incident surface 21, the first exit surface 22 and the reflective surface all extend along the first direction. The light-shielding shell 1 also extends along the first direction to cooperate with the first light-transmitting body 2. Reflective surfaces can be provided on both sides of the length direction of the first incident surface 21. The reflective surfaces on both sides can be defined as the first reflective surface 23 and the second reflective surface 24, respectively.

[0061] It is understandable that some of the light rays entering the first incident surface 21 can be directly emitted from the first exit surface 22, while other light rays are reflected by the reflecting surface and emitted from the first exit surface 22.

[0062] In some embodiments, a second light-transmitting body 3 is also included, which is disposed on the side of the first light-transmitting body 2 away from the first cavity 11, and the second light-transmitting body 3 is spaced apart from and opposite to the first emission surface 22.

[0063] The second light-transmitting body 3 can be made of a light-transmitting material. The second light-transmitting body 3 is positioned opposite the first emitting surface 22, allowing it to receive light emitted from the first emitting surface 22. The second light-transmitting body 3 can be an optical component with light-distribution capabilities, enabling it to readjust the light emitted from the first light-transmitting body 2 to meet specific light distribution requirements. It is understood that in optical design, to improve the utilization rate of light emitted by the light source 4, the shape and installation position of the first light-transmitting body 2 are often limited by various factors, making it difficult to freely adjust the first light-transmitting body 2 to achieve specific light distribution. In this embodiment, by setting the second light-transmitting body 3 on the light-emitting side of the first light-transmitting body 2, and by making the second light-transmitting body 3 relatively independent of the first light-transmitting body 2, it is convenient to obtain the required illumination by adjusting the second light-transmitting body 3.

[0064] The second light-transmitting body 3 includes a second incident surface 31 and a second exit surface 32. The second incident surface 31 and the second exit surface 32 are arranged opposite to each other. Light emitted from the first exit surface 22 can enter the second light-transmitting body 3 through the second incident surface 31 and finally exit from the second exit surface 32. The light can be adjusted by adjusting the shape and tilt angle of the second incident surface 31 and / or the second exit surface 32 so that the light emitted from the second exit surface 32 meets specific light distribution requirements. The adjustment of the light can include changing its light distribution angle and polarization, etc.

[0065] The second incident surface 31 is disposed opposite to the first exit surface 22, and there is a gap between the second incident surface 31 and the first exit surface 22. This gap makes the first exit surface 22 and the second incident surface 31 two relatively independent surfaces. During the propagation process, the light first passes through the interface between the first light-transmitting body 2 and the air, and then passes through the interface between the air and the second light-transmitting body 3. It can be refracted twice at the two interfaces. In some embodiments, the light can be polarized at this point by changing the angle between the second incident surface 31 and the first exit surface 22.

[0066] Furthermore, this gap allows light rays emitted from the first exit surface 22 at different angles to disperse in different directions, which helps to improve the uniformity of light distribution in the overall illumination and makes the illumination softer. For example, when the first exit surface 22 is perpendicular to the central axis 5 of the first light-transmitting body 2, the light rays are refracted at the interface between the first light-transmitting body 2 and the air. The angle of inclination of the refracted light rays relative to the central axis 5 is larger than that of the light rays before refraction. Light rays at different angles are dispersed at this point, thereby improving the uniformity of light distribution in the overall illumination.

[0067] In some embodiments, the light-shielding shell 1, the first light-transmitting body 2, and the second light-transmitting body 3 are integrally formed.

[0068] Preferably, the light-shielding shell 1 is made of an opaque colloid, including but not limited to silicone; the first light-transmitting body 2 and the second light-transmitting body 3 are made of a light-transmitting colloid, including but not limited to silicone; the silicone and other colloids can make the light-shielding shell 1, the first light-transmitting body 2 and the second light-transmitting body 3 flexible, so as to facilitate bending to meet the installation needs under specific conditions.

[0069] More preferably, the light-shielding shell 1, the first light-transmitting body 2, and the second light-transmitting body 3 are integrally formed using a two-color extrusion process; this can further simplify the manufacturing process and reduce manufacturing costs.

[0070] In summary, this embodiment provides a light strip that facilitates light distribution. The light-shielding shell 1 and the first light-transmitting body 2 enclose a first cavity 11 for placing the light source 4. The light-shielding shell 1 reduces light leakage of the light source 4 within the first cavity 11. The light-shielding shell 1 is integrally formed with the first light-transmitting body 2 and the second light-transmitting body 3, which reduces mold costs, simplifies assembly, and reduces the size of the lamp body. A reflective surface is provided between the first incident surface 21 and the first exit surface 22 of the first light-transmitting body 2. The reflective surface can reflect the light originally illuminating the side wall back to the first exit surface 22, improving light utilization. The second light-transmitting body 3 is spaced apart from and opposite to the first exit surface 22. The second light-transmitting body 3 can receive the light emitted from the first exit surface 22, and the light can be easily readjusted by changing the second light-transmitting body 3, including but not limited to adjusting its light distribution angle and / or polarization degree, to achieve specific light distribution and meet usage needs.

[0071] The light strip described in this embodiment, which facilitates light distribution, can reduce costs while still achieving specific light distribution.

[0072] In a preferred embodiment, the first light-transmitting body 2 mainly functions as a light-concentrating element; in this case, the first reflective surface 23 and the second reflective surface 24 are symmetrical about the central axis 5.

[0073] In another preferred embodiment, the first light-transmitting body 2 functions as a light-focusing and partially polarizing element, and the first reflective surface 23 and the second reflective surface 24 are configured such that the light reflected by the first reflective surface 23 and the light reflected by the second reflective surface 24 form a polarized beam, such as... Figure 7 As shown; at this time, the first reflecting surface 23 and the second reflecting surface 24 are asymmetrical about the central axis 5.

[0074] In both of the above preferred embodiments, the second light-transmitting body 3 can serve as a light-concentrating and / or light-polarizing agent; a specific light distribution angle can be formed by using second light-transmitting bodies 3 with different focal lengths; the polarization requirement can also be met by adjusting the tilt angle of the second incident surface 31 and the second exit surface 32, or by setting a polarizing microstructure on the second exit surface 32; the polarizing microstructure is, for example, a strip-shaped sawtooth protrusion.

[0075] In some embodiments, the width of the first exit surface 22 is greater than the width of the first incident surface 21.

[0076] like Figure 3 As shown, the width of the first exit surface 22 is D, and the width of the first incident surface 21 is d, where D > d. This allows more light to exit from the first exit surface 22, which helps to improve the light utilization rate.

[0077] In some embodiments, the width of the second incident surface 31 is greater than the width of the first exit surface 22.

[0078] like Figure 3 As shown, the width of the second incident surface 31 is b, b > D; this allows more light rays to enter the second incident surface 31.

[0079] In some embodiments, the first incident surface 21 and / or the first exit surface 22 and / or the first reflecting surface 23 and / or the second reflecting surface 24 and / or the second incident surface 31 and / or the second exit surface 32 are freeform surfaces.

[0080] Example 2

[0081] like Figures 1 to 4 As shown, this embodiment provides a light strip that facilitates light distribution. Based on embodiment 1, the light-shielding housing 1 includes a first side portion 13 and a second side portion 14 that are disposed opposite to each other. A connecting portion 15 is connected between the first side portion 13 and the second side portion 14. The connecting portion 15 is spaced apart from and opposite to the first incident surface 21. The first side portion 13 is opposite to the first reflective surface 23, and the second side portion 14 is opposite to the second reflective surface 24.

[0082] The first side 13, the second side 14, and the connecting part 15 refer to different parts of the light-shielding shell 1. The first side 13, the second side 14, and the connecting part 15 all extend along the first direction. In some embodiments, the cross-sectional shape of the light-shielding shell 1 is U-shaped, with the first side 13 and the second side 14 being the two sides of the U-shape, and the connecting part 15 being the bottom edge of the U-shape.

[0083] The connecting part 15 is spaced apart from and opposite to the first incident surface 21, and a space for mounting the light source 4 is formed between them; preferably, the first side part 13 is opposite to and spaced apart from the first reflecting surface 23, and the second side part 14 is opposite to and spaced apart from the second reflecting surface 24, so that the cross-sectional shape of the first cavity 11 is approximately U-shaped; it should be noted that the shape of the first cavity 11 may or may not be axially symmetric.

[0084] In some embodiments, a first groove 16 is provided on the first side portion 13, and a second groove 17 is provided on the second side portion 14. Both the first groove 16 and the second groove 17 face the first cavity 11 and are opposite to each other.

[0085] The first groove 16 and the second groove 17 can be used to snap the lamp board 6 and other structures, so that the light source 4 is stationary relative to the first light-transmitting body 2 and the second light-transmitting body 3; the light-shielding shell 1 can be made of flexible colloid, and the lamp board 6 can also be made of flexible material, so that the overall light strip has a certain degree of flexibility.

[0086] Example 3

[0087] This embodiment provides a light strip that facilitates light distribution. Based on embodiment 1 or 2, the first light-transmitting body 2 has mounting edges 25 on both sides, and the mounting edges 25 are connected to the light-shielding shell 1.

[0088] Mounting edge 25 is part of the first light-transmitting body 2. Mounting edge 25 can extend the reflective surface in the lateral direction, so that the reflective surface can be spaced apart from the light-shielding shell 1, leaving space for the shape change of the reflective surface.

[0089] Preferably, the two sides of the second light-transmitting body 3 are connected to the light-shielding shell 1, and the second light-transmitting body 3, the first light-transmitting body 2 and the light-shielding shell 1 enclose and form a second cavity 12.

[0090] In some embodiments, the first light-transmitting body 2 has a T-shaped cross-section, with the first exiting surface 22 located at the top of the T-shape, the first incident surface 21 located at the bottom of the T-shape, and the reflecting surface located on both sides of the abdomen of the T-shape.

[0091] In some embodiments, the second exit surface 32 is a convex curved surface.

[0094] The light source 4 can be an LED lamp bead; several LED lamp beads are arranged at intervals along the first direction.
