[0050] In addition, the expressions “first”, “second”, “third”, etc., which appear in the terms, are merely used to distinguish the description of the same or similar components and should not be understood as emphasizing or implying the relative importance of specific components.

[0053] Example 1
[0054] like Figure 1-2 As shown, a light-controllable LED flexible linear light comprises a flexible sleeve 1, a flexible LED substrate 2 and a flexible light-control component.
[0055] The flexible sleeve 1 is a linear structural member, that is, the length of the flexible sleeve 1 is much larger than its cross-sectional size. For example, the length of the flexible sleeve 1 is more than 5 times its cross-sectional size. In this way, it can be easily cut and spliced and can be used in various complex installation environments.
[0056] The flexible sleeve 1 is a flexible structure with a certain deformation ability, and can be made of materials such as silicone and PVC.
[0057] A mounting cavity is provided in the middle of the flexible sleeve 1 , and the mounting cavity is used to mount a flexible LED substrate 2 . The light emitted by the flexible LED substrate 2 is emitted through the flexible sleeve 1 .
[0058] In order to make the light emitted by the flexible LED substrate 2 reach a designated area, reduce the scattered light, and improve the light output efficiency of the lamp, the light transmittance at different positions of the flexible sleeve 1 can be set differently.
[0059] like Fig. 9 As shown, in one or more embodiments, the flexible sleeve 1 can be divided into a first area 11 and a second area 12, the light transmittance of the first area 11 is greater than that of the second area 12, and the flexible light control component is arranged in the first area 11. In this way, most of the light emitted by the flexible LED substrate 2 can be emitted through the first area 11, and then controlled by the flexible light control component, thereby improving the light extraction efficiency and facilitating light control, and meeting different light distribution requirements.
[0060] In a further solution, the first area 11 can be set to a transparent or light-transmitting structure with a certain degree of haze, and the second area can be set to an opaque structure (light transmittance is 0), so that most of the light can be further controlled to be emitted through the first area 11. In a specific process, a diffusing agent can be added to the first area 11, and titanium dioxide can be added to the second area 12 to form a milky white structure.
[0061] In order to facilitate the description of the technical solution, the present invention distinguishes the first area 11 and the second area 12. In actual products, the first area 11 and the second area 12 are usually an integrated structure. In this case, the first area 11 and the second area 12 are difficult to distinguish. However, as long as the transmittance of different positions of the flexible sleeve 1 is set differently, so that the transmittance of the light-emitting surface is greater than that of other areas, it belongs to the technical solution claimed by the present invention. Of course, in some special scenarios, the first area 11 and the second area 12 can also be two separate parts, which are fixed by bonding or other methods.
[0062] The present invention does not make any special limitation to this.
[0063] In a further solution, the second area 12 can form a reflective surface, that is, a reflective surface is provided in the mounting cavity of the flexible sleeve 1, so that most of the light can be emitted from the first area 11 through light reflection, and then controlled by the flexible light control component, thereby improving the light output efficiency and facilitating light control to meet different light distribution requirements. The reflective surface can be formed by attaching a reflective film or using a high reflectivity material to make the second area 12, such as a silicone or PVC material with titanium dioxide added.
[0064] The flexible LED substrate 2 is distributed along the extending direction of the flexible sleeve 1 , and the flexible LED substrate 2 is fixed in the mounting cavity of the flexible sleeve 1 .
[0065] The flexible LED substrate 2 is provided with a plurality of LED lamp beads. The flexible LED substrate 2 is a flexible structure with a certain deformation capability, and an aluminum substrate or the like may be used.
[0066] The flexible LED substrate 2 can be arranged along the extension direction of the flexible sleeve 1, that is, the flexible LED substrate 2 is a linear structural member, that is, the length dimension of the flexible LED substrate 2 is much larger than its cross-sectional dimension, for example, the length dimension of the flexible LED substrate 2 is more than 5 times its cross-sectional dimension, so that it can be conveniently cut and spliced, and can be applied to various complex installation environments.
[0067] In some special cases, the LED substrate 2 may also include a plurality of flexible LED substrate units arranged at intervals, each flexible LED substrate unit is used to install 1 or 2-8 LED lamp beads, and all flexible LED substrate units are arranged at intervals along the extension direction of the flexible sleeve 1. In this way, different light distribution schemes can be achieved by changing the length and interval of the flexible LED substrate units, and it is also easy to cut and splice, and can be applied to various complex installation environments.
[0068] The flexible light-controlling component 3 is fixed to the light-emitting surface of the flexible sleeve 1 , and is used to control the light emitted from the light-emitting surface of the flexible sleeve 1 .
[0069] The flexible light-controlling component 3 is a flexible structure with a certain degree of deformation capability, and can be made of silicone, PC, PET, etc.
[0070] The flexible light-control component 3 can be arranged along the extension direction of the flexible sleeve 1, that is, the flexible light-control component 3 is a linear structural component, that is, the length dimension of the flexible light-control component 3 is much larger than its cross-sectional dimension, for example, the length dimension of the flexible light-control component 3 is more than 5 times its cross-sectional dimension, so that it can be conveniently cut and spliced, and can be applied to various complex installation environments.
[0071] In some special cases, the flexible light control component 3 may include a plurality of spaced flexible light control units, all of which are spaced along the extension direction of the flexible sleeve 1. In this way, different light distribution schemes can be achieved by changing the length and interval of the flexible light control units, and it is also easy to cut and splice, and can be applied to various complex installation environments.
[0072] There are many ways to fix and connect the flexible light-controlling component 3 and the light-emitting surface of the flexible sleeve 1, and the present invention does not make any special limitation here.
[0073] The flexible light-controlling component 3 and the light-emitting surface of the flexible sleeve 1 may be connected in an assembled manner, so that different light distribution effects can be achieved by replacing the flexible light-controlling component 3 in different forms.
[0074] In one or more embodiments, the flexible light control component can be bonded and fixed to the flexible sleeve 1, so that it is not only easy to assemble and fix, but also different forms of flexible light control components can be replaced to achieve different light distribution schemes. The flexible light control component and the flexible sleeve 1 can be bonded by glue, for example, it can be high-viscosity silicone.
[0075] In this embodiment, the flexible light control component is a convex lens 3, and the convex lens 3 is fixed to the outer side of the light emitting surface of the flexible sleeve 1. In this way, the light emitting angle can be effectively limited to achieve small angle and medium angle light emitting, such as Figure 3 In a further embodiment, the convex lens 3 is preferably a silicone lens.
[0076] Example 2
[0077] like Figure 4-5 As shown, the difference between this embodiment and embodiment 1 is that the convex lens 3 in this embodiment is fixed on the inner side of the light emitting surface of the flexible sleeve 1. In this way, the light emitting angle can be effectively limited to achieve small angle and medium angle light emitting, such as Figure 6 shown.
[0078] In one or several embodiments, convex lenses 3 may also be provided on both the inner side and the outer side of the light emitting surface of the flexible sleeve 1 to further improve the light control capability.
[0079] Example 3
[0080] like Figure 7-8 As shown, the difference between this embodiment and embodiment 1 is that the flexible light control component in this embodiment is an optical film 4, and the optical film 4 is fixed to the inner side and / or outer side of the light emitting surface of the flexible sleeve 1. The optical film 4 can achieve light distribution effects such as light collection, single polarization, and double polarization.
[0081] The optical film 4 is a flexible structure with a certain degree of deformation capability, and can be made of PC film, PET film, etc.
[0082] like Fig.10 As shown, the optical film 4 may be a Fresnel light-collecting film 41 .
[0083] like Fig.11 As shown, the optical film 4 may be a double polarizing film 42 .
[0084] like Fig.12 As shown, the optical film 4 can be a single polarizing film 43 .
[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
