Flexible led patch light strip

Abstract

The invention relates to a decorative lighting device, and particularly relates to a flexible LED (light-emitting diode) patch lamp bar. The flexible LED patch lamp bar comprises a core wire, at least one flexible circuit board, and a cladding layer, wherein the core wire is a strip body with a preset length extruded and molded from flexible plastic; the flexible circuit board is provided with a plurality of patch electronic elements; the flexible circuit board is attached to the peripheral wall of the core wire; the cladding layer is extruded and molded from the flexible plastic, is equal to the core wire in length, and is non-light tight; the cladding layer is coated outside the core wire and the flexible circuit board; the flexible circuit board comprises a first bar body; the first bar body is arranged along the length direction of the core wire; a long edge of the first bar body is provided with a plurality of fins which are arranged at intervals and extend along the circumference of the core wire; the extension ends of all or partial fins are connected with at least one second bar body; the second bar body is arranged along the length direction of the core wire, and all or partial patch electronic elements are arranged on the fins. Compared with the prior art, the flexible LED patch lamp bar has the following beneficial effects that the fins of the flexible circuit board extend along the circumference of the core wire; LEDs can be distributed on the entire periphery of the core wire; 360-degree illumination of the periphery can be achieved, and the whole body lights to illuminate.

Description

technical field [0001] The invention relates to a decorative lighting device, in particular to a flexible LED patch light strip. Background technique [0002] Flexible LED SMD light strip has the characteristics of high brightness, long service life, energy saving and environmental protection, etc. It is widely used in the decorative lighting market, such as in signboards, subtitle advertisements, outlines of buildings, indoor ceiling lighting, and interior decoration of automobile bodies and other lighting places. The flexible LED patch light strip currently on the market is generally composed of a core wire, a flexible strip-shaped circuit board and a coating layer, and the LED patch is arranged on the flexible strip-shaped circuit board. Due to the limitations of LED patches, the existing light strips cannot achieve 360-degree lighting around the surface and emit light throughout the body. At the same time, the flexible strip circuit board and coating of the existing lig...

AI Technical Summary

Problems solved by technology

Due to the limitations of LED patches, the existing light strips cannot achieve 360-degree lighting around the surface and emit light throughout the body. At the same time, the flexible strip circuit board and coating of the existing light strips can only be bent at a specific angle, and cannot be bent at any angle. bend or twist
