Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The utility model provides a reinforcing backlight lamp strip module, as shown in figure 1. Including first lamp strip 10, second lamp strip 11, bridging FPC4, first lamp strip 10 second lamp strip 11 with bridging FPC4 integrated into one piece, first lamp strip 10 with bridging FPC4 junction is provided with first bending part 13, second lamp strip 11 with bridging FPC junction is provided with second bending part 14.

Further, as shown in fig. 2, the light bar module is n-shaped.

Staff two places FPC pad is twisted and is broken easily when the lamp strip of taking is whole to be assembled, leads to one side lamp pearl can't light or produce the rosin joint hidden danger, and the production yield is low, and the process is complicated with high costs. Above-mentioned design is for avoiding the difficult technical problem in the past, will lamp strip module is pi type improvement lamp strip module product luminance, reduces artifical and material cost simultaneously, optimizes backlight lamp strip FPC equipment yield, the stable backlight lamp strip design of reinforcing backlight unit.

Further, as shown in fig. 1, the first light bar 11 is connected with an FPC golden finger 8.

The FPC golden finger 8 is conducted with the first light bar 11 and is connected with an external power supply.

Further, as shown in fig. 1, first lamp strip 10, second lamp strip 11 all include lamp strip FPC7, weld in lamp strip FPC's lamp pearl, lamp strip FPC7 welding has the one side of lamp pearl is the light emitting area, the opposite face of light emitting area is non-light emitting area, non-light emitting area is provided with pad 9, lamp strip FPC7 is the bilayer around the pad 9 correspondence department.

Further, as shown in fig. 1A, the corresponding position of the pad 9 is staggered from the light-emitting surface light bar FPC7 of the first light bar 10 and the second light bar 11, the positive and negative electrodes of the pad 9 are staggered, and the FPC7 golden finger 8 is connected with the light bar FPC7 through the pad 9.
