Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Please refer to fig. 1-3;

the connecting wire used by the lamp string structure is not a coherent wire but consists of a plurality of disconnected connecting wires 1, a PCB (printed circuit board) 3 is welded in series between two adjacent connecting wires 1, the PCB 3 forms a metal circuit in the PCB by the prior art, and the manufacturing process is not repeated herein, in the embodiment, each connecting wire 1 at least comprises three wires which comprise two live wires and a ground wire, when in production, the outer layers of the end parts of the two adjacent wires are removed, the outer layers of the two live wires and the ground wire in the connecting wires 1 are also required to be removed to expose the metal connecting wire, when in production, the PCB 3 is put into a welding machine, then the live wires 23 of the two adjacent connecting wires 1 and the lamp component 2 are aligned to the welding point 31 of the PCB 3, so that the working efficiency is greatly improved compared with the manual welding required in the prior art, because the form of adopting PCB board 3 welding, the metal part that connecting wire 1 exposes can not too much, thereby the siphunculus welding point 31 is fixed can not take place the short circuit, consequently just need not to adopt and hinder and weld the processing, the step of using the sleeve pipe to carry out the insulation has been reduced, play the purpose that promotes the work yield equally, in addition still have two a bit, the connecting wire 1 that uses strips partial significantly reduction, can save the wire, and adopted PCB board 3 as middle conversion, except that the effect of switching on, can also increase components and parts on PCB board 3, provide the expansion space for follow-up research and development.

The lamp string can be divided into two forms, the first type is decoration use, the used lamp component 2 is a lamp bead, different lamp beads can emit light with different colors, the number of the lamp beads in the lamp string used for decoration use is large, the lamp string specifically comprises a support plate 24, a plurality of surface mounted LED lamp beads 25 are arranged on the support plate 24, and the light emitted by each surface mounted LED lamp bead 25 can be different; because a plurality of lamp assemblies 2 need to be connected in series in the lamp string used as decoration, the working efficiency is obviously improved in the aspect of processing by adopting the PCB 3 as a middle transmission mode; the second is lighting purpose, and more patch LED lamp beads 25 can be disposed on the carrier plate 24, each of which emits white light for lighting, in the present embodiment, the used lamp assembly 2 includes an LED bulb 22 and a bulb carrier 21, the bulb carrier 21 is similar to a connecting seat used in daily use for connecting and conducting with a bulb, and the LED bulb 22 and the bulb carrier 21 are detachable, that is, the LED bulb 22 can be replaced after being damaged;

in the present embodiment, the housing 4 is formed by injection molding, the housing 4 wraps the lamp assembly 2, the PCB 3, and the ends of two adjacent connecting wires 1, it should be noted that, when the lamp assembly 2 is a carrier plate 24 and an LED lamp bead, the whole can be wrapped, and the housing 4 is made of a transparent material, so that light can penetrate through the housing 4, when the lamp assembly 2 is an LED bulb 22 and a bulb carrier 21, the housing 4 only wraps the periphery of the bulb carrier 21, and an interface connected with the LED bulb 22 is reserved;

further extension in this embodiment, the welding has mutual electric connection's wireless communication module, control module and switch module on the circuit of PCB board 3, switch module is connected with lamps and lanterns subassembly 2, can control lamps and lanterns subassembly 2 through wireless transmission, and this mode is applicable to lamps and lanterns subassembly 2 quantity when less relatively more, for example: the number of the lamp assemblies 2 in the lamp string is 5 in common, so that the 5 lamp assemblies 2 can be independently controlled to be switched on and switched off, and when too bright illumination is not needed, the lamp assemblies 2 can be switched on at intervals, so that the power saving effect is achieved.
