Abstract

The utility model discloses a flexible SMD LED lamp strip which comprises a flexible circuit board, LEDs and resistors, wherein the flexible circuit board is provided with a coating layer; the LEDs and the resistors are arranged on the flexible circuit board; a graduated scale marked with standard millimeter graduations is arranged on the flexible circuit board; a shear tag line positioned between any two adjacent LEDs is arranged on the flexible circuit board; long strip-shaped bonding pads spanning the shear tag lines are respectively arranged on a positive pole copper-clad circuit and a negative pole copper-clad circuit of the flexible circuit board. The graduated scale is arranged on the flexible circuit board, and on the basis that one LED is a group, a section of the flexible SMD LED lamp strip with the minimum length of 1.7 cm is sheared, and the flexible SMD LED lamp strip with relatively accurate length can be accurately sheared through reference to the graduation mark of the graduated scale.

Description

A kind of flexible LED surface-mounted lamp band

Technical field

The utility model belongs to the technical field of LED illumination, relates in particular to a kind of flexible LED surface-mounted lamp band structure.

Background technology

LED light source has the life-span long (100,000 hours), excitation is high, color reproduction rate is high, brightness is high, be not afraid of low temperature, strong adaptability good reliability, without advantages such as mercury pollution, low power consumption, low heatings, continuous progress along with LED technology, brightness constantly promotes, and LED will become the main flow device of back lighting.

Along with LED product becomes the main flow that existing market is lighting field, LED product has also produced the LED light fixture of various luminosity and function, and flexible LED surface-mounted lamp band is wherein a kind of application LED lamp very widely.Flexible LED surface-mounted lamp band on existing market is all generally that 3 LED are set is one group of LED group on flexible PCB, by the flexible PCB calculating and setting of 1 meter of length, there are 30 LED, i.e. 10 groups of LED groups, one group of LED group length of 3 LED compositions is 5cm, and the length of shearing minimum one section of flexible LED surface-mounted lamp band is 5cm.During each shearing, need measure in advance length, put on mark and shear as line of reference, very very complicated, time-consuming again; And the accuracy of shearing is easily because of thinking that mistake in computation produces deviation, cause flexible LED surface-mounted lamp band shearing inaccuracy and the waste that brings.

Summary of the invention

The deficiency existing for existing LED lamp band, the utility model provides a kind of flexible LED surface-mounted lamp band, this flexible LED surface-mounted lamp band is provided with graduation mark on flexible PCB, when shearing, can relative shear go out lamp strip length accurately, improved the free degree that lamp band is sheared, reduced lamp band and sheared the waste that inaccuracy is brought.

To achieve these goals, the utility model provides a kind of flexible LED surface-mounted lamp band, comprise be provided with clad flexible PCB, be located at LED and resistance on flexible PCB, on described flexible PCB, be carved with the rule of standard millimeter scale, be also provided with the shearing tag line arranging between adjacent LED; On the deposited copper circuit of positive and negative electrode of FPC, be respectively equipped with across the strip pad of shearing on tag line.On flexible PCB, being provided with rule, is one group by a LED, and the minimum length of shearing one section of flexible LED surface-mounted lamp band is 1.7cm, with reference to the scale mark of rule, can accurately shear out relatively accurate flexible LED surface-mounted lamp band length.

Further, adjacent two flexible PCBs are that positive and negative electrode applies overlapping rear corresponding connection of copper circuit, and the junction of each electrode is provided with main joint face and auxiliary joint face, and superimposed joint face middle part is provided with aperture.The aperture arranging can make the scolding tin after adjacent two flexible PCBs connect dissolve in aperture, plays same function and effect that this rivet of class is connected and fixed.

In sum, flexible LED surface-mounted lamp band of the present utility model is compared traditional LED lamp band, can when shearing, can relative shear go out lamp strip length accurately, has improved the free degree that lamp band is sheared, and has reduced lamp band and has sheared the waste that inaccuracy is brought.

Fig. 2 is adjacent two exploded views that flexible PCB is connected.

The specific embodiment

With specific embodiment, the utility model is further described below.

Embodiment 1

A kind of flexible LED surface-mounted lamp band, as shown in Figure 1, comprise be provided with clad flexible PCB 1, be located at LED2 and resistance 3 on flexible PCB, on described flexible PCB, be carved with the rule 4 of standard millimeter scale, be also provided with the shearing tag line 5 arranging between adjacent LED; On the deposited copper circuit of positive and negative electrode of FPC, be respectively equipped with across the strip pad 6 of shearing on tag line.On flexible PCB, being provided with rule, is one group by a LED, and the minimum length of shearing one section of flexible LED surface-mounted lamp band is 1.7cm, with reference to the scale mark of rule, can accurately shear out relatively accurate flexible LED surface-mounted lamp band length.

Further, as shown in Figure 2, adjacent two flexible PCBs are that positive and negative electrode applies overlapping rear corresponding connection of copper circuit, and the junction of each electrode is provided with main joint face and auxiliary joint face, and superimposed joint face middle part is provided with aperture 7.The aperture arranging can make the scolding tin after adjacent two flexible PCBs connect dissolve in aperture, plays same function and effect that this rivet of class is connected and fixed.

Above-described embodiment is only some preferred embodiments of the present utility model; not limit according to this protection domain of the present utility model; therefore: all various equivalences of doing according to structure of the present utility model, shape, principle change, within all should being encompassed in protection domain of the present utility model.
