Problems solved by technology

[0002] LED light strips are more and more widely used in the decorative lighting market due to their long service life, energy saving and environmental protection. The current LED flexible light strips are usually composed of lamp beads and flexible printed circuit boards (FPC for short). However, in the production process of flexible circuit boards, various heavy metals and organic wastewater are discharged, the composition is complex, and the treatment is difficult. If the metals in the waste liquid and wastewater are discharged without treatment, it will cause waste. polluted the environment
And the production of flexible circuit boards (single-sided system) mainly includes cutting, drilling, pasting dry film, alignment, exposure, development, etching, stripping, surface treatment, pasting cover film, pressing, curing, surface treatment, sinking, etc. Nickel gold, printing characters, cutting, electric measurement, punching and other processes, many production steps, complex production process

Embodiment 1

[0028] like Figure 1 to Figure 3 As shown, a method for making a light strip is characterized in that it includes the following steps:

[0029] Step 1, the flexible conductive metal strip is stamped as a whole to form a circuit base strip 1, and the circuit base strip 1 has a plurality of line strips 2 arranged in parallel directions; wherein, the line strips 2 are provided with two The first power supply line 3 and the second power supply line 4, and a plurality of component lines 5 connected between the first power supply line 3 and the second power supply line 4, each of the component lines 5 is provided with a plurality of The lamp bead installation area arranged in M×N matrix.

[0030] The circuit belt 2 in the present invention is integrally stamped and formed by a bendable conductive metal belt. The overall circuit layout is accurate and stable, and the production process is less, no printed circuit is needed, waste materials are easy to recycle, less environmental po...

Embodiment 2

[0039]Compared with Embodiment 1, the main difference of this implementation is that when the output voltages of the first power supply line 3 and the second power supply line 4 are greater than the sum of the rated voltages of the lamp beads 6 of each of the component lines 5 , the second step further includes the following steps: mounting the resistance element 9 on the element line 5 and connecting it in series with the lamp bead 6 of the same element line 5 through a soldering mounting process. By setting the resistance element 9, it can act as a voltage divider to prevent the actual voltage of the lamp bead 6 from being higher than the rated voltage, thereby damaging the lamp bead 6, and avoiding potential safety hazards caused by long-term use.

[0040] More preferably, the transparent insulating film 7 is injection-molded on the entire outer surfaces of the element circuit 5 , the lamp bead 6 and the resistance element 9 and part of the outer surfaces of the first power ...

Abstract

The invention relates to a manufacturing method of a lamp strip. The manufacturing method comprises the steps that a conductive metal strip capable of bending is wholly stamped into a circuit base strip, and the circuit base strip is provided with a plurality of circuit strips; each circuit strip is provided with a first power circuit, a second power circuit and an element circuit, and each element circuit is provided with a plurality of lamp bead mounting areas arranged in an M*N array mode; lamp beads are mounted at the lamp bead mounting areas in a pasted mode through soldering; transparentinsulating films are injected and molded on the entire outer surfaces of the element circuits and the lamp beads and the partial outer surfaces of the first power circuit and the second power circuitcorrespondingly; areas, not wrapped with the transparent insulating films, of the first power circuit and the second power circuit serve as a positive pole connecting area and a negative pole connecting area, and by adopting a connecting mode that M lamp beads are connected in parallel and then N sets of lamp bead sets composed of the M lamp beads are connected in series, disconnecting is conducted at the corresponding positions at the element circuits in a stamping work procedure; and the circuit strips are cut and separated, and manufacturing of the lamp strip is completed. By adopting themanufacturing method, the effects that printed circuits are not needed, the manufacturing technology is simple, pollution is less, and the cost is low can be achieved.
