Extrusion type linear lamp strip with protection function

Abstract

An extrusion type linear lamp strip with protection comprises a base plate, a plurality of lamp beads are arranged on the end face of the base plate, the base plate is coated with a bonding layer and dried, and the extrusion type linear lamp strip further comprises silica gel covering the base plate. A solid silica gel cold extrusion process is combined and used on the basis of a traditional SMT bare board lamp strip, and the novel solid silica gel extruded bare board LED lamp strip is formed. Through solid silica gel covering, components on the surface of the lamp strip are well protected from being corroded by external dust or corrosive gas, stress borne by the components when the bare board lamp strip is twisted is shared, and the components are effectively protected and are not prone to being broken and damaged; and meanwhile, by increasing or decreasing the number of components such as lamp beads on the bare board lamp strip and changing the color form of the solid silica gel, various flexible lamp strips with different light-emitting effects are combined and generated.

Description

Technical Field

[0001] This utility model relates to the field of linear light strips, and more particularly to an extruded linear light strip with protection. Background Technology

[0002] Flexible LED strip technology is rapidly evolving, with various new technologies emerging, many of which are based on bare-board surface mount (FPCB) LED strips. Currently, there are three main types of mature bare-board LED strips: the first is the traditional SMT surface mount technology, which typically uses traditional packaged LED chips such as 2835 as the light source; the second is the rapidly developing COB flexible LED strip, which often uses blue flip-chip surface bonding and fluorescent silicone coating processes; and the third is a COB-like flexible LED strip, which often uses SMT surface mount technology with silicone coating, and typically uses small-sized 2025 LED chips as the light source.

[0003] Of the three technical solutions mentioned above, the first, traditional SMT surface mount technology, has a relatively long history of development, is mature, and has low cost. Its disadvantage is that the LED chips and other components are exposed without protection, especially vulnerable to damage from FPCB board twisting. The second, COB flexible LED strip, is a relatively recent development, but the technology is now quite mature. The flip-chip light source is protected by fluorescent silicone covering. However, the flip-chip lacks support, making it prone to electrode detachment or breakage, resulting in defects and inconvenient repairs, which typically require cutting off the defective section and replacing it with a good one. The third, a COB-like flexible LED strip, uses surface coating, usually requiring multiple coating processes to form, making production inconvenient and costly. Therefore, a product and process combining the advantages of all three—a protective extrusion method and a linear LED strip—is needed. Utility Model Content

[0004] To address the aforementioned issues, this technical solution provides a protective extruded linear LED strip.

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

[0006] A protective extruded linear LED strip includes a substrate with a plurality of LED beads on its end face, the substrate being coated with an adhesive layer and dried, and also includes silicone covering the substrate.

[0007] In some embodiments, the silicone is extruded onto the substrate by cold extrusion.

[0008] In some embodiments, the LED beads are arranged in multiple rows side by side, and the silicone is also arranged in multiple rows.

[0009] In some embodiments, LED beads are provided on both ends of the substrate, and each LED bead is provided with silicone.

[0010] The beneficial effects of this application are:

[0011] Compared to existing technologies, this application innovates the production process and structural scheme of flexible LED strips. It combines traditional SMT (Surface Mount Technology) bare board LED strips with a solid silicone cold extrusion process to create a novel solid silicone extruded bare board LED strip. This invention effectively protects the components on the strip surface from external dust or corrosive gases by covering them with solid silicone, distributing the stress on the components when the bare board strip is twisted, thus providing effective protection against breakage and damage. Furthermore, by increasing or decreasing the number of LED chips and other components on the bare board strip and changing the color and shape of the solid silicone, various flexible LED strips with different luminous effects can be combined and generated.
