Water-proof LED flexible light stripe and its manufacturing method

Abstract

The invention provides a waterproof LED flexible optical strip, including an LED flexible optical strip which is coated with a colloid layer which is spliced with a tegmen; meanwhile, the invention also provides a preparation method of the waterproof LED flexible optical strip. The invention has the advantages that the products of the waterproof LED flexible optical strip have high quality reliability and good application safety, the method has low manufacturing cost, and mass yield can be realized; furthermore, the invention can produce arbitrary length according to requirement, which has extremely high product yield and superiority which is incomparable with other waterproof LED flexible optical strips.

Description

technical field [0001] The invention relates to the field of decoration, in particular to a waterproof LED flexible light strip and a preparation method thereof. Background technique [0002] At present, due to the soft texture of the LED flexible light strip, the large luminous angle, the soft and uniform light, and the characteristics of being able to be bent arbitrarily and being extremely convenient to install, it is widely used in shopping malls, hotels, and entertainment venues for interior decoration, shopping mall lighting layout, and exhibitions. , display, exhibition layout. [0003] However, the electronic components on the LED flexible light strip are exposed to the outside, easy to fall off or easily damaged by external forces, and because they are very soft and weak in strength, they are easy to break; moreover, the PCB board of the LED flexible light strip is very soft and the components are in poor contact. Or excessive bending is also easy to jump away; and...

Problems solved by technology

The biggest disadvantage of this method is: large-scale production requires a large number of molds; the cost of the mold is very high; the position of the LED flexible light strip in the mold is not easy to determine; due to the length limitation of the mold, only fixed-length products can be produced, and cannot Too long (currently the longest is 1.2 meters); the shape is affected by the mold and has a process edge, which will affect the application of side lighting; because the colloid is used directly, the colloid itself is relatively weak in strength, and it is easier to break or tear after being subjected to external force

Its biggest disadvantage is: because a large number of electronic components protrude from the surface of the LED light strip, it will hinder the flow of plastic during extrusion molding, generate air bubbles, deformation, etc., and the yield is very low; Stretching and contact with the mold cause component damage or flexible PCB board breakage: Due to the high unit price of LED flexible light strips and the low yield rate, the unit price of the product will increase significantly
