Manufacturing method of lamp strip

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.

Description

technical field [0001] The invention relates to the field of lighting equipment, and more specifically, to a method for manufacturing a light strip. Background technique [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. And pollute 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 fi...
