A method for manufacturing patch-type LED light strings and light strings manufactured by the method

Abstract

The invention discloses a surface mount device type LED lamp string manufacturing method and a lamp string manufactured with the method. The manufacturing method sequentially includes the following steps: wire winding; polishing soldering lamp foot areas; cutting wires through an upper clamping plate; soldering tin applying; soldering lamps and disassembling clamping plates and jigs; packaging an extruder; connecting a plug or a power source. A surface mount device type LED lamp string comprises a first wire, a second wire and a plurality of surface mount device type LED lamps, the middle of the first wire is cut into a plurality of equal-length sections, conductors at the head end and the tail end of each section of the first wire are exposed, one surface mount device type LED lamp is welded between the ends of two adjacent sections of the first wire, the welding directions of the positive electrodes and the negative electrodes of all the surface mount device type LED lamps are the same, the surface mount device type LED lamps accordingly form the lamp string in series, and the in-series lamp string and the second wire are packaged into one rubber body in parallel. The in-series surface mount device type LED high-pressure lamp string is even in luminance, good in interspersing effect and high in manufacturing process mechanical automation degree.

Description

technical field [0001] The invention relates to a string of lighting lamps, in particular to a string of patch LED lamps. Background technique [0002] In order to achieve better lighting and decoration effects, SMD LED light strings are widely used, such as building exterior decoration, room interior decoration, park, square decoration, etc., everywhere. At present, there are high-voltage and low-voltage LED light strings, and the conductor material and the LED lamp beads are all encapsulated in the colloid. [0003] However, the existing LED light strings are usually low-voltage. In order to achieve highly automated lighting operations (that is, the LED lamp beads are welded to the wires by a machine), most of them use two-wire parallel connection of multiple LEDs to connect the LEDs. Then connect the LED light strings in parallel or in series. The input voltage is fixed. There are two common types: 12V and 24V, so it is usually low voltage, because it is mainly connected...
