The specific embodiment

Fig. 2 is the module schematic diagram backlight of the utility model one embodiment.Please refer to Fig. 2, module 200 backlight of the present utility model comprises a lamp box 210, a plurality of fixed leg 220 and a plurality of fluorescent tubes 230.Wherein, fixed leg 220 is disposed at lamp box 210 bottoms.As shown in Figure 2, fixed leg 220 cross section areas can be toward the two ends convergent.Certainly, have in the affiliated technical field and know the visual actual needs of the knowledgeable usually and the profile of appropriate change fixed leg 220, painstakingly do not limit at this.On the practice, the material of this fixed leg 220 for example is an elastomeric material, fits together in order to fluorescent tube 230 and fixed leg 220.Module backlight 200 of the present utility model also can comprise a conductive layer 212 and a circuit board 214.Conductive layer 212 is disposed at the bottom in the lamp box 210, and circuit board 214 is disposed at the bottom outside the lamp box 210.The fixed leg 220 that is disposed at lamp box 210 bottoms can wear conductive layer 212 and circuit board 214 in the lump.

On the other hand, fluorescent tube 230 is disposed in the lamp box 210.This fluorescent tube 230 for example is a fluorescent tube.Certainly, have in the affiliated technical field and know the visual actual needs of the knowledgeable usually and the profile of appropriate change fluorescent tube 230 painstakingly is not confined to the fluorescent tube 230 of vertical bar shape at this, fluorescent tube 230 also can be a curved shape.Two ends that it should be noted that the utility model fluorescent tube 230 have a plurality of ring-type seal wires 232 respectively.Ring-type seal wire 232 is inserted in pairing fixed leg 220 respectively, so that fluorescent tube 230 is located.Specifically, because the material of fixed leg 220 is an elastomeric material, therefore when ring-type seal wire 232 was inserted in fixed leg 220, fixed leg 220 was subjected to the extruding of ring-type seal wire 232, the cross section area of fixed leg 220 can make things convenient for ring-type seal wire 232 to be inserted in toward the two ends convergent.After ring-type seal wire 232 is inserted in fixed leg 220, fixed leg 220 no longer is subjected to the extruding of ring-type seal wire 232 and resiles, and the fixed leg 220 that resiles also can avoid ring-type seal wire 232 to come off from fixed leg 220, so ring-type seal wire 232 can firmly combine with fixed leg 220.In other words, fluorescent tube 230 need not just can reach the purpose of location by known soldering technology.This can make module backlight 200 of the present utility model have the advantage and the quite environmental protection of the assembly and disassembly of being easy to.In addition, the ring-type seal wire of fluorescent tube 230 232 can and conductive layer 212 electrically connect and then conductive layer 212 and electrically connecting by this with side by side fluorescent tube 230.

Fig. 3 is the module schematic diagram backlight of another embodiment of the utility model.Please refer to Fig. 3, fixed leg 220 of the present utility model can be double-screw bolt.Module 200 ' backlight can comprise that also one is locked in the locking part 222 on the fixed leg 220, and this locking part 222 for example is a nut.Fluorescent tube 230 of the present utility model can reach the purpose of location equally by fixed leg 220 with locking part 222.

In sum, fluorescent tube of the present utility model can be inserted in the fixed leg and need not just can make fluorescent tube reach the purpose of location by soldering by the ring-type seal wire.Therefore, fluorescent tube of the present utility model has the advantage and the quite environmental protection of the assembly and disassembly of being easy to.
