Description
Technical field
This utility model belongs to household appliance technical field, is specifically related to a kind of LED lamp bar.
Background technology
Liquid crystal display screen in available liquid crystal TV is divided into LCD liquid crystal display screen and LED liquid crystal display screen two kinds, and liquid crystal display screen itself is not luminous, its luminescence be by liquid crystal panel after backlight realize.LCD liquid crystal screen backlight is made up of a plurality of fluorescent tube lighted through hardboard, is called for short LCD backlight.LED liquid crystal screen backlight is made up of LED lamp bar (parallel connection after multiple LED strip connection or series connection), is called for short LED-backlit.Mostly the LCD TV of early stage is based on LCD backlight, due to LED-backlit simple in construction, and has power saving, and the feature that brightness is high has all replaced LCD backlight.
In LCD liquid crystal display screen backlight failure is keeped in repair, owing to LCD backlight cost is high, accessory difficulty is looked for, maintenance trouble, is progressively reequiped by the LED lamp bar of existing LED-backlit and replaces.But existing LED lamp bar is all come customized according to each LCD TV size, does not match that with LCD liquid crystal display screen to be repaired, LED lamp bar repacking is caused to replace cumbersome, inefficiency.
Utility model content
In view of this, the purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of can free cutting and freely weld prolongation LED lamp bar.
For realizing object above, this utility model adopts the following technical scheme that a kind of LED lamp bar, and including substrate and be arranged at least two LED on described substrate the same face, described LED is connected in series；Being provided with severing line on the substrate between two adjacent described LED, described LED lamp bar is divided into the LED elementary cell that some structures are identical by described severing line；
Described LED elementary cell includes unit LEDs lamp, unit LEDs lamp positive wire, unit LEDs lamp cathode conductor and the public cathode conductor of unit, adjacent LED lamp elementary cell said units LED positive and negative electrode wire is connected and forms LED series loop, and the adjacent LED lamp public cathode conductor of elementary cell said units is connected and forms public cathode conductor；
Being additionally provided with loop solder joint pair in described LED elementary cell, a loop solder joint of described loop solder joint centering is connected with described unit LEDs lamp cathode conductor, and another loop solder joint is connected with the public cathode conductor of described unit.
The intersection, edge of two adjacent described LED elementary cells is provided with pad.
Described pad is surface-mount type rectangular pads.
The quantity of described LED is 2～8.
The quantity of described LED is 5.
Described LED elementary cell is additionally provided with installation through hole.
This utility model adopts above technical scheme, has the identical LED elementary cell of some structures and loop solder joint pair due to LED lamp bar, when relatively liquid crystal display screen is big for LED lamp bar size, can freely be cut to applicable size from severing line；Owing to the edge of LED elementary cell is provided with pad, when LED lamp bar size is little compared with liquid crystal display screen, applicable size can be extended to by pad solder.So adopt the LED lamp bar of said structure, can the various liquid crystal display screen size of flexible adaptation, make LED lamp bar repacking replacement process easy, improve the efficiency of repacking.
