LED lamp string

Abstract

The invention discloses an LED lamp string, which comprises at least two LED bases and a connecting circuit, wherein the LED base is provided with at least two LEDs; the LED bases are connected by the connecting circuit; and the connecting circuit comprises a power supply positive wire, a power supply negative wire and a signal control wire. The LED base is provided with three to ten LEDs arranged on the LED bases in at least one of the following arrangement modes: linear arrangement, cross arrangement, circular arrangement or customized patterns. The connecting circuit of the LED lamp stringis provided with only one signal wire. The LEDs are fixed on the corresponding LED base by adopting the scheme and using single wire transmission so that the connecting wire between the LED bases is simpler, and the LED lamp string has the advantages of material saving, simple connection, convenient use, high reliability, diversified combination and significant decorative effect.

Description

technical field [0001] The invention relates to a lamp string, in particular to an LED lamp string. Background technique [0002] At present, decorative lights in the form of light strings have been widely used in various places, and use their changeable shapes to show colorful decorative effects. There are discrete LED light string groups on the connecting line, the lamp body has poor heat dissipation and high power consumption, and is not suitable for long-term use. Moreover, the illuminant of the light string has a single shape, no special style of expression, and the decorative effect is not good; When the series is connected with the main line, there are generally two input heads, two output heads, one power connector and one signal connector. Due to the large number of connectors, the failure rate of the connectors is high, the reliability is low, and it is easy to cause short circuits and dropouts. And other problems, the signals interfere with each other, resulting ...

[0002] At present, decorative lights in the form of light strings have been widely used in various places, and use their changeable shapes to show colorful decorative effects. There are discrete LED light string groups on the connecting line, the lamp body has poor heat dissipation and high power consumption, and is not suitable for long-term use. Moreover, the illuminant of the light string has a single shape, no special style of expression, and the decorative effect is not good; When the series is connected with the main line, there are generally two input heads, two output heads, one power connector and one signal connector. Due to the large number of connectors, the failure rate of the connectors is high, the reliability is low, and it is easy to cause short circuits and dropouts. And other problems, the signals interfere with each other, resulting in a limited length of the cascade

[0003] Therefore, the existing LED light strings still have inconveniences and shortcomings in practical life applications, and need to be innovated and improved.
