Flexible LED (light emitting diode) paster strip light

Abstract

The invention relates to a decorative illuminating device, in particular to a flexible LED (light emitting diode) paster strip light which comprises a core wire, a plurality of flexible strip type circuit boards and a coating layer, wherein the core wire is provided with a groove internally and longitudinally, besides, at least two leads are embedded in the core wire, and the leads are arranged longitudinally and have the same length with the core wire; each circuit board is provided with at least one row of LED pasters, two ends of each circuit board are respectively provided with at least one lead wire, the lead wires are connected with the leads, which form a return circuit and provide electricity for the LED pasters on the circuit boards, and all the circuit boards are arranged in thegroove, and gaps exist between the adjacent circuit boards in the length direction and are in an interrupted shape; and the coating layer is coated outside the core wire and the circuit boards. The flexible LED paster strip light provided by the invention can be connected with 220V commercial power, a low-voltage power supply is not required to be allocated, the production cost is lowered, and the length of the strip light can be manufactured for no less than 100 meters.

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 patch light strip (LED flexible 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, building outlines, indoor ceilings Lighting, automotive body interior decoration and other lighting places. At present, the flexible LED patch light strips on the market are generally composed of flexible strip circuit boards (such as FPC flexible circuit boards), resistors, LED patches (also called LED patch lamp beads, which refer to separately packaged LED chips, which contain one or Multiple LEDs) and cladding layers, LED patches and resistors are set on the circuit board, and the power line is also directly set on the circuit board. However, beca...

Problems solved by technology

However, because the copper foil of the circuit board is used as the power line, it cannot withstand high current, so it is necessary to configure a low-voltage power supply when using it, resulting in high production costs. At the same time, the use of low-voltage power supply limits the length of a single circuit board and the number of LED patches.
