Abstract

The utility model discloses a light-emitting strip capable of being cut randomly, which comprises a circuit board, wherein the circuit is connected with a plurality of light-emitting diode (LED) lamps to form an LED lamp string through conducting wires. The light-emitting strip capable of being cut randomly further comprises a strip-shaped flexible pipe, the LED lamp string is wrapped inside the strip-shaped flexible pipe, and the LED lamps in the LED lamp string are all in parallel connection. The strip-shaped flexible pipe directly wraps the existing LED lamp string in plastic injection mode; the LED lamp string can be firmly fixed in the flexible pipe, and thereby being convenient and simple. The light-emitting strip capable of being cut randomly is simple in process and low in cost. A reinforcing strip is added to increase the bending-fatigue resistance intensity of the light-emitting strip, and the service life of the light-emitting strip can be prolonged. All LED lamps in the LED lamp string are in parallel connection, the working of the LED lamp string can not be affected when the tail portion of the LED lamp string is randomly cut, thereby being convenient in use. The strip-shaped flexible pipe can be manufactured into different colors and shapes, thereby being attractive and varied in appearance, when being matched with the lamp string, the decorative effects are good.

Summary of the invention

The utility model purpose is: overcome the defective of prior art, provide a kind of with low cost, can change length at any time to adapt to the light-emitting section that cuts randomly of different length.

The technical scheme that utility model provides is as follows: a kind of light-emitting section that cuts randomly, include a circuit board, circuit board is connected with several LED lamps by lead and constitutes a LED lamp string, also includes a strip flexible pipe, and strip flexible pipe internal package described LED lamp string.

As an improvement of the present utility model, in the described light-emitting section that cuts randomly, comprise that also at least one reduces its bending curvature to increase the stiffener of its bend resistance fatigue strength, described strip flexible pipe internal package described stiffener.

As an improvement of the present utility model, in the described light-emitting section that cuts randomly, described lead comprises at least two leads, wherein one is positive wire, article one, be cathode conductor, two pins of described several LED lamps are electrically connected described positive and negative electrode lead respectively, that is: described several LED lamps are to be connected in parallel.

As preferably, in the described light-emitting section that cuts randomly, the quantity of described lead is three, i.e. cathode conductor, and two positive wires, two pins of described several LED lamps are electrically connected described adjacent positive and negative electrode lead respectively.

As an improvement of the present utility model, in the described light-emitting section that cuts randomly, described several LED lamps can be equidistant distributions, also can be that unequal-interval distributes; LED lamp between the adjacent positive negative conductor can be distribution straggly, also can be aligned fashion.

As preferably, in the described light-emitting section that cuts randomly, described strip flexible pipe is the member that a transparent plastic is made

The utlity model has following advantage: adopt the strip flexible pipe directly to wrap up original LED lamp string in the injection moulding mode, LED lamp string can firmly be fixed on flexible pipe inside, and is convenient and simple, technology is simple, and is with low cost, increases by a stiffener, can increase its bend resistance fatigue strength, improve the life-span; Each and every one LED lamp in the LED lamp string all is connected in parallel, and cutting randomly its afterbody does not influence its work, easy to use; The strip flexible pipe can be made into different CFs, and is aesthetic in appearance changeable, cooperates the lamp string, good decorating effect.

The specific embodiment

Below in conjunction with accompanying drawing concrete embodiment is illustrated:

Embodiment one, as depicted in figs. 1 and 2, a kind of light-emitting section that cuts randomly, comprise a circuit board 1, draw two copper conductors 2 on the

circuit board

1,3, wherein one is anodal copper conductor 2, another is a negative pole copper conductor 3, just described, negative pole copper conductor 2, its vertically equally spaced several LED lamps 4 that are electrically connected with of 3 upper edges constitute a LED lamp string, also include the soft solid tubes 5 of a circle, adopt transparent plastic to make, portion is wrapped in described LED lamp string within it, in described soft solid tubes 5 inside, also be enclosed with two and reduce the stiffener 6 of light-emitting section bending curvature to increase its bend resistance fatigue strength.

During use, start-up circuit plate 1, circuit board 1 is being controlled the on and off of all LED lamps 4 by

copper conductor

2,3, in actual effect, can demonstrate LED lamp 4 flicker effect, long bright effect like this, certainly can control arbitrarily in time, as one second bright and went out in one second, five seconds bright and went out in five seconds, ten seconds bright and flicker effect such as went out in a second, be provided with and can add corresponding sensor, according to the light on and off state of outside sound, humidity, temperature or the like factor control LED lamp; And described flexible pipe 5 can bend to different shapes, and annular, arc and square or the like make decorative effect more rich and varied.

Embodiment two, as shown in Figure 3 and Figure 4, a kind of light-emitting section that cuts randomly comprises a circuit board 1, draws three

copper conductors

2,3 on the circuit board 1, wherein two is anodal copper conductor 2, another is a negative pole copper conductor 3, and its vertically equally spaced several LED lamps 4 that are electrically connected with of described adjacent positive and negative

electrode copper conductor

2,3 upper edges constitute a LED lamp string, also include an oval-shaped soft solid tubes 5, the employing translucent plastic is made, and portion is wrapped in described LED lamp string within it.LED lamp between LED lamp 4 string on the adjacent positive and negative
