[0033] Referring to FIGS. 1 to 3, a preferred embodiment of an LED surface-mounted extrusion structure according to the present utility model comprises: at least one LED bead 1, wherein in the present utility model, the number of LED beads 1 is not limited and can be set according to actual needs; a light board 2 for powering the LED bead 1 to light at least one LED bead 1; a light-blocking silicone portion 3 for blocking the propagation of light at least one angle when the LED bead 1 is lit; and a light-transmissive silicone portion 4 for dispersing, at least one angle, the light propagating outward when the LED bead 1 is lit, wherein the light-transmissive silicone portion 4 is colored silicone, wherein the light-blocking silicone portion 3 and the light-transmissive silicone portion 4 are integrally connected,and the light-blocking silicone portion 3 and the light-transmissive silicone portion 4 surround a cavity 5 for accommodating the light panel 2 and at least one LED bead 1. In the LED surface-mounted extrusion structure according to the present utility model, the light-transmissive silicone portion 4 and the light-blocking silicone portion are configured as an integrated structure, so that the extrusion structure appears to have better integrity and be simpler, can be implemented with both color and dispersion, can be mounted and used in an extremely narrow and extremely short space (for example, with a minimum narrowness of 3 mm and a shortness of 2.5 mm), emits more uniform light, improves luminous efficiency, and has a smaller thickness than that of a conventional process.

[0034] In the present utility model, a manufacturing method in which the light-blocking silicone portion 3 and the light-transmissive silicone portion 4 are integrally connected is not limited. In an alternative embodiment, the light-blocking silicone portion 3 and the light-transmissive silicone portion 4 may be integrally connected by a molding process of extruding a silicone material into a mold. In other embodiments, the light-blocking silicone portion 3 and the light-transmissive silicone portion 4 may be integrally connected by a multi-adhesive dripping process into a mold, or the light-blocking silicone portion 3 and the light-transmissive silicone portion 4 may be integrally connected by other suitable processes.

[0035] The preferred embodiment of the LED surface mounted extrusion structure according to the present utility model may have the following additional technical features.

[0036] Referring to FIGS. 4-8, in an alternative embodiment, an inner surface of the light transmissive silicone portion 4 proximate the LED bead 1 has a diffusion pattern 6, and the diffusion pattern 6 allows light to be scattered and spread in the light-transmissive silicone portion 4 when the LED bead 1 is turned on. In this way, the light emitted by the LED bead 1 can be fully dispersed, the light transmitting through the light-transmissive silicone portion 4 is more uniform, and the LED surface-mounted extrusion structure according to the present utility model has a better luminous effect. Referring to FIGS. 3 and 9 to 12, in other embodiments, the light-transmissive silicone portion 4 may be provided without a diffusion pattern 6. In other embodiments, the diffusion pattern 6 may be arranged on an outer surface of the light-transmissive silicone portion 4 away from the LED bead 1.

[0037] In an alternative embodiment, an outer surface of the light-transmissive silicone portion 4 remote from the LED bead 1 has a convex shape to facilitate the dispersion of light propagating outward when the LED bead 1 is turned on. In this way, the light emitted by the LED bead 1 can be more uniformly emitted from the light-transmissive silicone portion 4, and the LED surface-mounted extrusion structure according to the present utility model has a better luminous effect. Referring to [Fig. 9], in other embodiments, the outer surface of the light-transmissive silicone portion 4 remote from the LED bead 1 may be non-convex.

[0038] In the present utility model, the shape of the outer surface of the light-transmissive silicone portion 4 remote from the LED bead 1 is not limited and can be configured according to an actual situation. In an alternative embodiment, the convex shape is domed, so that the uniformity of the light emitted by the LED bead 1 after the light is emitted from the light-transmissive silicone portion 4 can be further improved, resulting in a better luminous effect of the LED surface-mounted extrusion structure according to the present utility model. In other embodiments, the convex shape may be flat, or the convex shape may be irregular, or the convex shape may have other suitable shapes.

[0039] In some application scenarios, the LED surface-mounted extrusion structure according to the present utility model needs to be bent during assembly. Therefore, in an alternative embodiment, the light panel 2 is a flexible circuit board, so that the light panel 2 is flexible. When the LED surface-mounted extrusion structure according to the present utility model needs to be bent during assembly, the light panel 2 can be bent smoothly without being damaged, so that the LED surface-mounted extrusion structure according to the present utility model can be adapted to more application scenarios. In other embodiments, the light panel 2 may be a rigid circuit board.

[0040] In an alternative embodiment, the light-blocking silicone portion 3 is made of opaque silicone, and an inner surface of the light-blocking silicone portion 3 close to the LED bead 1 can reflect light. In this way, the light emitted by the LED bead 1 can pass more intensely through the light-transmissive silicone portion 4, so that the utilization rate of the light emitted by the LED bead 1 is increased, and the LED surface-mounted extrusion structure according to the present utility model has a better luminous effect. In other embodiments, the light-blocking silicone portion 3 may be made of light-transmissive silicone. In other embodiments, a portion of the light-blocking silicone portion 3 may be made of opaque silicone, and the remainder may be made of light-transmissive silicone. Referring to [Fig.7], the light-blocking silicone portion 3 is arranged around the light-transmissive silicone portion 4, and the portion of the light-blocking silicone portion 3 which is on an outer surface of the light-transmissive silicone portion 4 away from the LED bead 1 is made of light-transmissive silicone.

[0041] In an alternative embodiment, the colored silicone comprises the following colors or one or more colors selected from a group comprising the following colors: milk white, black, blue, green, orange, yellow, red, and purple, to enable color matching with the environment in which the LED surface-mounted extrusion structure is mounted. In this way, a user can choose a colored silicone with an appropriate color according to actual needs, and thus the LED surface-mounted extrusion structure according to the present utility model can adapt to more application scenarios.

[0042] In the present utility model, the structure of the light-transmissive silicone portion 4 is not limited and can be configured according to actual needs. Referring to FIGS. 3, 4 and 8, in an alternative embodiment, the light-transmissive silicone portion 4 comprises an inner silicone layer 7 and an outer silicone layer 8 surrounding the inner silicone layer 7.With the above structure, when the outer silicone layer 8 of the light-transmissive silicone portion 4 is damaged, the inner silicone layer 7 of the light-transmissive silicone portion 4 can protect the LED bead 1 and the light panel 2, thereby preventing substances, such as external water droplets and impurity particles, from contacting the LED bead 1 and the light panel 2, reducing damage to the LED bead 1 and the light panel 2, and improving the reliability and stability of the LED surface-mounted extrusion structure according to the present utility model. Referring to FIGS. 5 to 7 and 9 to 12, in other embodiments, the light-transmissive silicone portion 4 may be of a single-layer silicone structure.

[0043] In an alternative embodiment, the number of light-transmissive silicone parts 4 and the number of light-blocking silicone parts 3 are each greater than or equal to 1, and the light-transmissive silicone parts 4 and the light-blocking silicone parts 3 are arbitrarily arranged to surround the cavity 5 to accommodate the light panel 2 and at least one LED bead 1. In this way, the user can select an appropriate number of light-transmissive silicone parts 4 and an appropriate number of light-blocking silicone parts 3 according to actual needs, so as to obtain a suitable LED surface-mounted extrusion structure.

[0044] In an alternative embodiment, the light-transmissive silicone portion 4 and the light-blocking silicone portion 3 are arranged on the light panel 2. With the above structure, the overall structure of the LED surface-mounted extrusion structure according to the present utility model is more stable. In other embodiments, it is possible that the light-transmissive silicone portion 4 and the light-blocking silicone portion 3 are not arranged on the light panel 2.

[0045] Referring to FIGS. 3 to 7, in an alternative embodiment, the light-transmissive silicone portion 4 and the light-blocking silicone portion 3 surround a back surface of the light panel 2 on which no LED bead 1 is arranged. With the above structure, the LED bead 1 and the light panel 2 can be protected more comprehensively, and external impacts on the LED bead 1 and the light panel 2 can be reduced, thereby reducing damage to the LED bead 1 and the light panel 2 and realizing higher safety and reliability. In other embodiments, the light-transmissive silicone portion 4 and the light-blocking silicone portion 3 may surround a portion of the back surface of the light panel 2 on which no LED bead 1 is arranged. Referring to FIGS.8 to 12, it is possible that the light-transmissive silicone part 4 and the light-blocking silicone part 3 do not surround the back surface of the light panel 2 on which no LED bead 1 is arranged.

[0046] It can be understood that the LED surface-mounted extrusion structure is less aesthetic due to a belt mark present on a lower surface of the light-blocking silicone portion 3 during the manufacture of the LED surface-mounted extrusion structure. Therefore, referring to FIGS. 1 to 3 and 5, in an alternative embodiment, a concave-convex structure 9 is provided on a lower surface of the light-blocking silicone portion 3. The provision of the concave-convex structure 9 can on the one hand allow the belt mark on the lower surface of the light-blocking silicone portion to be removed so that the LED surface-mounted extrusion structure according to the present utility model is more aesthetic, and on the other hand, can save the material for the manufacture of the light-blocking silicone portion 3. Referring to FIGS. 4, 6 and 7, in other embodiments, it is possible to not provide a concave-convex structure 9 on the lower surface of the light-blocking silicone portion 3, or another suitable form of structure may be provided on the lower surface of the light-blocking silicone portion 3 to remove the belt mark.

[0047] Referring to FIGS. 1 to 7, in an alternative embodiment, a transparent strip 10 enabling viewing of a cutting line on the light panel 2 is provided on the light-blocking silicone portion 3. In this way, the user can clearly see the cutting line on the light panel 2, and thus the LED surface-mounted extrusion structure according to the present utility model can be cut more accurately according to actual needs. Referring to FIGS. 8 to 12, in other embodiments, it is possible to omit the transparent strip 10 from the light-blocking silicone portion 3, and another suitable structure or component can be provided on the light-blocking silicone portion 3 instead of the transparent strip 10.

[0048] Those skilled in the art may freely combine and use the above additional technical features in combination with each other, provided that no conflict arises.

[0049] An embodiment of the present utility model further provides an LED light strip, comprising: an LED surface-mounted extrusion structure as described above. The LED light strip according to the embodiment of the present utility model comprises the above-mentioned LED surface-mounted extrusion structure. Therefore, the light-transmissive silicone portion 4 and the light-blocking silicone portion are also configured as an integrated structure, so that the LED light strip appears to have better integrity and be simpler, can be implemented with both color and dispersion, can be mounted and used in an extremely narrow and extremely short space (e.g., with a minimum narrowness of 3 mm and a shortness of 2.5 mm), emits more uniform light, improves luminous efficiency, and has a smaller thickness than that of a conventional process.

[0050] The above-mentioned implementations are only preferred implementations of this utility model and cannot be intended to limit the scope of protection of this utility model. Any non-substantial changes and replacements made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
