Abstract

The utility model relates to a two lines and two circuits LED lamp string(band), which is characterized in that two transfer lines are connected in parallel with two groups of loop units which consist of a plurality of LED and resistances, and the LED in the same group have a same direction, but the direction of LED of the groups of the parallel connection unit are contrary, thereby, the LED loop unit is capable of having a plurality of consisted lamp strings(bands); the LED which are in the same unit and the directions are contrary are capable of being combined crossly in interval, thereby, according to the direction of the supplied current, the light-emitting diodes LED are crossly blinking, forming a beautiful neon lamp world. The utility model has the advantages of simple structure, low cost and good effect; the utility model is a neon lamp string(band) in the new generation.

Description

Two wires two paths of LEDs lamp strings (band)

The utility model relates to a kind of neon lamp belt, especially the neon lamp belt of two wires two tunnel.

In existing neon lamp belt, add a unilateral diode before the miniature bulb of employing and come to determine whether flicker according to the sense of current, cost is higher like this, complex structure, the life-span is short, and power consumption is many.

The utility model purpose provides a kind of simple in structure, low cost, long-life, the two wires two paths of LEDs lamp strings (band) of low power consumption.

For achieving the above object, the utility model adopts following organization plan, promptly utilize unilateral conduction and the illuminator of LED to replace bulb and diode, just on two power transmission lines, two groups of circuit units of being made up of several LED and resistance are connected in parallel, LED direction on the same group is identical, but two groups of LED directions of unit, shunt circuit are opposite, and such unit, LED shunt circuit can have numerous.

Because in the shunt circuit, adopted with the shunt circuit of two prescriptions in the technique scheme to opposite LED and resistance, so, simple in structure, because the LED life-span is very long, so, the life-span of having improved whole neon lamp belt, and reduce power consumption.Simultaneously, because of LED has seven, eight kind of color, can select the LED of different colours as required.

Describe present embodiment in detail below in conjunction with accompanying drawing.

Accompanying drawing is two wires two paths of LEDs lamp string (band) theory structure schematic diagrames.

As shown in the figure, two power transmission lines 1,2, respectively be parallel with the loop of two groups of LED3 and electricity group 4 thereon, LED3 direction on the same group is identical, but two groups of LED3 directions in the unit in parallel are opposite, the loop that such LED3 and resistance 4 are formed can have numerous, and LED3 that can the direction in the unit, shunt circuit is opposite as required is staggered spaced apart, according to the sense of current, and the LED3 flicker, flow, because it is low that LED3 has a power consumption, life-span is long, and cost is low, so, the utlity model has simple in structure, low cost, the life-span is long, advantage of low energy consumption, and LED can select different colors as required, is the new generation product of neon light string (band).

Claims

1, a kind of two wires two paths of LEDs lamp strings (band), it is made up of a plurality of LED (3) and two power transmission lines (1) (2), it is characterized in that: on two power transmission lines (1) (2), be connected in parallel to two groups of circuit units of forming by several LED (3) and resistance (4), unit, shunt circuit LED (3) direction on the same group is identical, but LED (3) direction of each group of unit in parallel is opposite, such LED circuit units can have numerous, LED (3) the interleaved combination on request that same shunt circuit cell orientation is opposite.
