Description

Technical Field

[0001] This utility model relates to the field of neon light strips, and more particularly to a neon light strip with an optical structure. Background Technology

[0002] Today, flexible neon light strip technology is advancing rapidly, and flexible neon products with various processes are emerging one after another. Among them, the two mainstream flexible light strips are LED patch bare board light strip + PVC hot extrusion process (hereinafter referred to as PVC neon) and LED patch bare board light strip + silicone cold extrusion process (hereinafter referred to as silicone neon).

[0003] Of the two technical solutions mentioned above, PVC neon technology, which was developed earlier and is more mature, is relatively cheaper than silicone neon. However, its disadvantage is that the material is prone to aging, discoloration, and brittleness over time. Silicone neon technology, developed relatively later, is also relatively mature. Its advantages include resistance to discoloration and aging, and more stable material properties. Both of these solutions use bare LED chip strips, which have drawbacks. Excessive twisting of the strip during use can easily lead to stress damage to components. Furthermore, the color temperature parameters of the finished product will drift significantly compared to the bare strip, making it difficult to control consistency during production. Therefore, there is an urgent need for a new product that overcomes these shortcomings: a neon strip with an optical structure. Utility Model Content

[0004] To solve the above problems, this technical solution provides a neon light strip with an optical structure.

[0005] To achieve the above objectives, the technical solution is as follows:

[0006] A neon light strip with an optical structure includes a substrate, a plurality of LED beads are provided on the end face of the substrate, the substrate is coated with an adhesive layer and dried, and also includes silicone covering the substrate.

[0007] It also includes a light-blocking silicone covering the outer periphery of the substrate, the light-blocking silicone also having a diffusing silicone for diffusing the light emitted by the lamp beads, and the diffusing silicone also having a transparent silicone.

[0008] In some embodiments, the silicone is extruded onto the substrate by cold extrusion.

[0009] In some embodiments, the diffused silicone is designed with an inclined surface, and the outer diameter gradually decreases from top to bottom.

[0010] In some embodiments, the substrate is located on the sidewall of the light-blocking silicone, and the diffuser silicone has an enclosing cavity that covers the substrate after being inserted into the silicone.

[0011] The beneficial effects of this application are:

[0012] Compared to existing technologies, this application innovates the production process and structural scheme of flexible LED strips. It combines a silicone cold extrusion process with a silicone neon integrated extrusion molding process on the basis of traditional SMT bare board LED strips, creating a novel silicone extruded neon LED strip. This invention, through silicone coating, distributes the stress on components during the twisting of the bare board LED strip, effectively protecting components such as LED beads and resistors. The LED bead surface is coated with two types of silicone with different refractive angles, which effectively corrects color temperature drift in the finished product, ensuring consistency. Furthermore, by increasing or decreasing the number of LED beads and other components on the bare board LED strip and changing the color and shape of the silicone, various silicone neon LED strips with different luminous effects can be combined and generated.
