Problems solved by technology

[0008] A. The light guide is not easy to install and is easy to fall off;
[0009] B. The insulating sheath is extruded by an extruder. Since the patch LED is a certain distance above the flexible circuit board, the insulating sheath cannot be bonded to the flexible circuit board. Once the insulating sheath is aged and broken, water will easily flow along the insulating sheath. and the gap between the flexible circuit board and the flow to the conductor, which will cause a short circuit to damage the lamp body or even cause a fire

Embodiment Construction

[0047] Refer to Figure l to Figure 5The preferred embodiment of the present invention is shown: a patch LED light string, including a strip-shaped flexible LED lamp board 1, and the strip-shaped flexible LED lamp board 1 is a plurality of patch-type LEDs 2 that are spaced apart from each other and are flat. Pasted on the surface of the flat strip-shaped flexible circuit board 3, the light-emitting surface of the patch LED 2 is provided with a light guide 4, and the periphery of the flexible LED light board 1 and the lower end of the light guide 4 are injection-molded with or adopt high-frequency continuous A layer of insulating sheath 5 is formed by high-frequency welding, and the insulating sheath 5 and the flexible LED light board 1 and the light guide 4 form an integrated structure that closely fits. Form a tightly fitting integrated insulating sheath 5 on the periphery of the LED light board 1 and the lower end of the light guide 4 by means of injection molding or high-fr...

Abstract

The invention discloses a chip LED type lamp string which comprises a strip-shaped flexible LED lamp panel. The chip LED type lamp string is characterized in that according to the strip-shaped flexible LED lamp panel, a plurality of chip type LEDs are flatly attached to the surface of a flat-tape-shaped flexible circuit board in a mutually spaced manner, the light-emitting faces of the chip type LEDs are provided with light-guiding bodies, the periphery of the flexible LED lamp panel and the lower end of each light-guiding body are provided with a layer of insulated skin in an injection molding or high-frequency welding manner, and the insulated skin, the flexible LED lamp panel and the light-guiding bodies are of a closely-attached integrated structure. The invention furthermore discloses a fabrication method of the chip LED type lamp string at the same time. The chip LED type lamp string has the advantages of being low in cost, good in waterproof effect and good in light-emitting effect.

Description

technical field [0001] The invention relates to a decorative lighting device, in particular to a patch LED lamp string and a manufacturing method thereof. Background technique [0002] LED has many advantages such as energy saving, environmental protection, safety, long life, small size, etc., and is widely used in the field of decorative lights; among them, the flexible long strip LED light strings are deeply loved by the people, and a large number of LED light strings are used every year. For holiday decorations at home and abroad. [0003] The general structure of the existing LED light strings is as follows: a plurality of in-line LEDs are connected in series with thin wires, waterproof glue is applied on the positions where the wires and LEDs are welded, and a heat-shrinkable sleeve is put on. The disadvantages of this structure are: [0004] A. The use of in-line LEDs can only be soldered by manual or semi-automatic machinery, which is inefficient and high in labor c...
