Flexible LED soft lamp band and production process thereof

Abstract

The invention discloses a flexible LED soft lamp band and a production process thereof. The flexible LED soft lamp band comprises a lamp band body and a pouring sealant layer. An upper flexible band is arranged above the lamp band body in the length direction of the lamp band body. The pouring sealant layer is wrapped outside the lamp band body and the upper flexible band through the extruding or extrusion molding process. The traction tensile strength of the lamp band body can be enhanced through the upper flexible band, and the lamp band body is not likely to be snapped during the extruding or extrusion molding process. The upper flexible band can protect LED chips and circuit elements on the lamp band body through thermal insulation during the extruding or extrusion molding process. The upper flexible band has the high-temperature insulation effect, and the qualified rate of products can be increased. Further, the upper flexible band is a diffusion film, and the pouring sealant layer is a diffusion sealant layer. Light emitted by the LED chips is subjected to secondary diffusion and light mixing of the diffusion sealant layer and the diffusion film correspondingly. The diffusion effect is good, and light spots and dazzle light are effectively reduced.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to a flexible LED soft light strip and a production process thereof. Background technique [0002] Traditional LED light strips are usually sealed directly on the main body of the LED light strip through extrusion or extrusion processes to achieve waterproof, protective functions, and lighting effects such as diffusion and color matching. However, in the production process of LED light strips, usually It is necessary to pull the main body of the light strip through the extrusion or extrusion equipment on the other side of the extrusion or extrusion equipment. When the traction force is improperly configured or the conveying resistance increases, the light strip is easily broken, and the extrusion or extrusion The process requires high-temperature melting, which can easily affect the LED chips and other circuit components on the main body of the LED strip, reducing the pass rate of the product. ...
