Problems solved by technology

[0003] Traditional soft light strips are divided into monochrome soft light strips, RGB soft light strips, and point-controlled soft light strips. The basic components are composed of electronic components and LEDs (such as 3528LEDs, 5050LEDs) mounted on flexible PCBs by welding technology. Form PCB semi-products, and then the PCB semi-products are extruded through epoxy glue and silicone sleeves to form different products. Traditional LED soft light strips are made of packaged LEDs and then welded on the flexible PCB, which has poor heat dissipation and large light decay. Short service life and expensive

Embodiment

[0045] Below with reference to accompanying drawing of specification sheet ①-(12), present embodiment is described further:

[0046] 1. The electronic components (M2) are mounted on the flexible PCB (M1) by welding technology, as shown in Figure ②;

[0047] 2. The LED chip is fixed on the flexible PCB board (M1) by bonding technology to form an LED bare chip package and form a single bare board N2, as shown in Figure ④;

[0048] 3. Multiple single bare boards (N2) are welded end to end to form a multi-bare board (N3) as shown in Figure ⑤;

[0049] 4. Solder electronic wires at one or both ends of the multi-bare board (N3) to form a multi-bare board half product (N5) as shown in Figure ⑦;

[0050] 5.1) Multi-bare board semi-products (N5) without cladding constitute product P1; as shown in Figure ⑧

[0051] 2) Multi-bare board semi-products (N5) penetrate the silicone sleeve to form product P2; as shown in Figure ⑨

[0052] 3) Multi-bare board semi-product (N5) components are...

Abstract

The invention relates to a novel technical scheme for producing an LED (Light Emitting Diode) soft light bar and belongs to the technical field of LED landscape and decorative illumination application. The traditional soft light bar is poor in radiating property, high in light depreciation, short in service life and high in cost. According to the novel technical scheme, an LED chip is directly attached to a flexible PCB (Printed Circuit Board). The novel technical scheme has the advantages: 1) the LED chip is directly packaged on the PCB, the LED bracket for packaging the LED and the complex production technology are omitted, the cost is greatly saved and the market potential is huge; 2) the surface of the LED chip is clung to a PCB copper sheet, and the thermal resistance is less than one time of the thermal resistance of the packaged LED radiated through pins, such as 3528LED, 5050LED, and the like, used by the traditional soft light bar, so that the service life is longer; and 3) the LED chip is directly attached to the PCB, so that the area occupied by the LED is smaller, the product is smaller and the cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of LED landscape and decorative lighting applications, and relates to a production technical scheme of LED soft light strips (or called LED flexible light strips); Background technique [0002] Common LED landscape decorative lights include soft light strips, guardrail tubes, pixel lights, wall washers, etc., which are widely used in landscape lighting and building decoration. Because of its various colors, beautiful and compact appearance, and easy installation, the soft light strip has been widely used in various occasions such as indoor and outdoor decorative lighting and landscape lighting. [0003] Traditional soft light strips are divided into monochrome soft light strips, RGB soft light strips, and point-controlled soft light strips. The basic components are composed of electronic components and LEDs (such as 3528LEDs, 5050LEDs) mounted on flexible PCBs by welding technology. Form PCB semi-products, ...
