Abstract

The utility model discloses an improved flexible lamp strip and belongs to the field of decorative illumination application. The lamp strip mainly comprises a first coverage film, a second coverage film and a metal conduction layer, wherein the first coverage film is adhered to a first surface of the metal conduction layer; the second coverage film is adhered to a second surface of the metal conduction layer; the first surface of the metal conduction layer is provided with an LED (Light Emitting Diode) bonding pad and a control device bonding pad; the LED bonding pad and the control device bonding pad project from the first coverage film; a plurality of grooves are designed on the second surface of the metal conduction layer; and the grooves are located right under the LED bonding pad to form vertical one-to-one symmetric relation. The improved flexible lamp strip provided by the utility model has the beneficial effect that when the lamp strip is bent, the force direction is changed, so that the LED bonding pad is not separated from the metal conduction layer, the quality of the flexible lamp strip is guaranteed, and at the same time damage to LEDs is avoided; the production process is simple, and the production efficiency is greatly improved.

Description

A kind of follow-on flexible light band

[affiliated technical field]

The utility model relates to the decorative lighting application, relates in particular to a kind of follow-on flexible light band.

[background technology]

Because fast development along with the LED technology; Especially the application of flexible light band more and more widely; The LED flexible light band that it is made into is widely used in living and the central every field of industry, for example illumination places such as advertisement and identifier edge light, contour of building illumination, tree crown, corridor, the illumination of indoor smallpox, park decorative lighting.

Yet, for the part terminal applies field of flexible light band, no matter be in life or industrial upward more and more longer for the length requirement of flexible light band; For example relatively commonly used about 3-10 rice; Perhaps 10-50 rice, even plurality of applications field need be more than 50 meters, more than 100 meters; Even about 200 meters, this just means the requirement that fracture energy also will reach length of bearing of flexible light band.But present most of flexible light bands are thinner, and ability to bear is low, does the length of length like this, easily fracture; Therefore, in order to reach such length requirement, most thickness that increase flexible light band that adopt reach such length requirement.

Just as described above, the thickness that increases flexible light band no doubt can be accomplished desired length, but because flexible light band is long and thickness increases; The LED pad separates with metal conducting layer easily during bending; Cause component failure, even the LED damage, cause the whole piece flexible light band to lose efficacy, can't work.

[summary of the invention]

In order to solve above-mentioned existing technical deficiency and defective, the purpose of the utility model is to provide a kind of follow-on flexible light band.

The purpose of the utility model realizes through adopting following technical scheme:

A kind of follow-on flexible light band; Comprise first coverlay, second coverlay and metal conducting layer; Said first coverlay is covered on the first surface of said metal conducting layer; Said second coverlay is covered on the second surface of said metal conducting layer; The first surface of said metal conducting layer is provided with LED pad and control device pad, and said LED pad and control device pad expose from said first coverlay, it is characterized in that: the second surface at said metal conducting layer is designed with some grooves.

As the optimal technical scheme of the utility model, said groove be positioned at said LED pad under, form man-to-man symmetric relation up and down.

As the optimal technical scheme of the utility model, said groove can be designed as square type groove, round groove or special-shaped groove.

As the optimal technical scheme of the utility model, said metal conducting layer is copper foil layer or aluminium foil layer, also can be the tinfoil paper layer.

As the optimal technical scheme of the utility model, said first coverlay and said second coverlay all are resistance weldering insulation material.

Compared with prior art; The beneficial effect that the utlity model has is: the metallic conduction laminar surface of flexible light band and be positioned at the LED pad under design groove; Changed in the time of bending and received force direction; The LED pad can not separated with metal conducting layer, guaranteed the quality of flexible light band, avoid the damage of LED simultaneously; Production technology is simple, has improved production efficiency greatly.

[specific embodiment]

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

With reference to accompanying drawing 1,2, a kind of follow-on flexible light band mainly comprises: first coverlay (1), metal conducting layer (2), LED pad (3), control device pad (4), groove (5).

This follow-on flexible light band comprises first coverlay (1), second coverlay (unmarked among the figure) and metal conducting layer (2).In the present embodiment; Said first coverlay (1) is covered on the first surface (unmarked among the figure) of said metal conducting layer (2); Said second coverlay is covered on the second surface (unmarked among the figure) of said metal conducting layer (2), and first coverlay (1) and second coverlay all are resistance weldering insulation material; The first surface of said metal conducting layer (2) is provided with LED pad (3) and control device pad (4); In the present embodiment, metal conducting layer (2) is a copper foil layer, but is not limited thereto, also can be according to the designing requirement of flexible light band, metal conducting layer (2) is designed to aluminium foil layer or the tinfoil paper layer waits other metal conducting layers; Said LED pad (3) passes from said first coverlay (1) with control device pad (4); Promptly can directly see LED pad (3) and control device pad (4), and can LED (unmarked among the figure) and control device (unmarked among the figure) be welded on the pad from first coverlay (1) front.

In the utility model, be designed with some grooves (5) at the second surface of said metal conducting layer (2).Said groove (5) can be designed as square type groove, round groove or special-shaped groove, and present embodiment adopts square type groove; Said groove (5) be positioned at said LED pad (3) under; Form man-to-man symmetric relation up and down, the position thickness attenuation that belongs to of LED pad (3) has like this changed in the time of bending and has received force direction; LED pad (3) can not separated with metal conducting layer (2); Guaranteed the quality of flexible light band, avoided the damage of LED simultaneously, guaranteed that flexible light band can long-term work.

The material of said first coverlay (1) and said second coverlay all is a resistance weldering insulation material.On the one hand, when being welded on LED and control device on the pad, play the effect of resistance weldering; On the other hand, play insulating effect, improved security.
