Double-row and multiple-row LED lamp baseband

Abstract

The invention relates to a double-row and multiple-row LED lamp baseband. The double-rows and multiple-row LED lamp baseband comprises a circuit baseband and lamp beads; the circuit baseband is formedby integrally punching a bendable conductive metal band; a plurality of circuit strips are formed on the conductive metal band; each circuit strip is provided with a first power circuit, a second power circuit and a plurality of element circuits, wherein the element circuits are connected in parallel; each element circuit is provided with a plurality of lamp bead installation regions which are arranged in an MXN matrix form, wherein in the lamp bead installation regions, M lamp beads are firstly connected in parallel and subsequently N lamp bead groups consisting of the M lamp beads are connected in series; the lamp beads are installed at the lamp bead installation regions in an adhering manner; the element circuits, the overall outer surface of the lamp beads, and a part of the outer surfaces of the first and second power circuits are each coated with a transparent insulating film; a region, which is not coated with the transparent insulating film, of each first power circuit is usedas an anode connecting region; and a region, which is not coated with the transparent insulating film, of each second power circuit is used as a cathode connecting region. The double-row and multiple-row LED lamp baseband provided by the invention has the advantages of needing no printing circuit and being simple to manufacture, low in pollution and low in cost.

Description

technical field [0001] The invention relates to the field of lighting equipment, more specifically, to a double-row and multi-row LED lamp base 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 ...
