Description
Technical field
The utility model relates to a kind of LED light bar fixing device and LED-backlit module.
Background technology
Liquid crystal indicator has the characteristics such as quality is light, thickness is little, low in energy consumption, radiation is little, has been widely used in information technology, and the various fields such as multimedia technology become the main flow of various display unit.Because liquid crystal panel itself is not luminous, need extra light source to provide light source for it, so just produced backlight source of liquid crystal display apparatus.Generally speaking, the backlight source module light source mainly contains cathode fluorescent tube (CCFL) and two kinds of light-emitting modes of light emitting diode (LED).The cathode fluorescent tube mercury that contains hazardous substance, be undoubtedly a kind of injury for environmental protection, and the cathode fluorescent tube life-span is short, directly affects the service life of liquid crystal indicator.That light emitting diode has is pollution-free, long-life, vibration resistance, shock resistance and free of contamination characteristics, therefore the light-emitting modes of LED as backlight that adopt now more.
The mode backlight of liquid crystal indicator is side entering type, straight-down negative, because the module of straight-down negative is thicker, do not meet the frivolous little development trend of liquid crystal panel, therefore the side entrance back module will have larger development space, the side entering-type LED backlight module is divided into side entering type and grows limit LED-backlit module and two kinds of formation of side entering type minor face LED-backlit module, and Fig. 1 only illustrates side entering type to grow the structural representation of limit LED-backlit module.
As shown in Figure 1, the long limit of side entering type LED-backlit module 10 comprises: glue frame 11, blooming piece 12, LGP 13, reflector plate 14, backboard 15 and LED lamp bar 16; Wherein LED lamp bar 16 is positioned on the long limit or minor face of LED-backlit module, LED lamp bar 16 is connected on the long limit of backboard 15, LED lamp bar 16 is by a metal fin 151(as shown in Figures 2 and 3) be fixed on backboard 15, the light source sent by LED lamp bar 16, and then provide liquid crystal panel required light source.
In the available liquid crystal back light model setting technology, the LED lamp bar of side backlight module generally leans on sticking double faced adhesive tape or is screwed on metal fin, Figure 2 shows that employing sticking double faced adhesive tape fixed L ED lamp bar, Figure 3 shows that employing screw fixed L ED lamp bar.
Be illustrated in figure 2 and adopt sticking double faced adhesive tape LED lamp bar, with double faced adhesive tape 20, LED lamp bar 16 is fixed on metal fin 151, metal fin 151 is fixed on backboard 15.The defect of this LED fixed form is: paste a pair precision during sticking double faced adhesive tape LED lamp bar and be not easy to control, and it is poor to repeat workability, operation inconvenience, greatly affected packaging efficiency.
Be illustrated in figure 3 and adopt screw fixed L ED lamp bar, use screw 30 on metal fin 151, then is fixed on LED lamp bar 16 fixing and lockings on backboard 15 by metal fin 151.The defect of this LED fixed form is: because LED lamp bar is the sheet material of strip, in the time of fixedly, need to use many screws to fix, and need special-purpose tool for twisting screw during operation, operation is inconvenient, the activity duration is longer, complex process, production efficiency is low, and production cost is high.
Therefore need the mode of a kind of new fixed L ED lamp bar of design.
