The specific embodiment
See also Fig. 2 and Fig. 3, Figure 2 shows that schematic diagram, Figure 3 shows that the generalized section along the AA line of the module backlight among Fig. 2 according to module backlight of the present invention.Be that side-light type module backlight is an example with module 1 backlight in the present embodiment, module 1 backlight comprises lampshade 2, a plurality of luminescence component 8, LGP 4 and at least one support member.Each luminescence component 8 comprises a plurality of light emitting diodes 3 and circuit board 5, and these light emitting diodes 3 electrically are arranged on the circuit board 5, and extends arrangement along the long side direction of lampshade 2 formed light source disposal areas.Light emitting diode 3 for example can utilize the mode of welding or pressing to combine with circuit board 5, and wherein circuit board 5 is preferably flexible printed wiring board (FPC), but in different embodiments, circuit board 5 also can be the material of printed circuit board (PCB) (PCB) or other type.LGP 4 is arranged at light-emitting area 31 sides of light emitting diode 3, and the incidence surface 41 of LGP 4 is adjacent with light-emitting area 31, the light that light emitting diode 3 is sent by light-emitting area 31 can enter the incidence surface 41 of LGP 4, can evenly be directed to the exiting surface 42 of LGP 4 afterwards, provide even and bright light source to display floater through blooming piece (not illustrating).Wherein, LGP 4 for example can utilize the method for ejection formation, with transparent light guide materials such as polymethyl methacrylates, make smooth surface or have the class wedge shape of pattern, site or the plate of class rectangle, but the present invention is not as limit.
Lampshade 2 comprises sidewall 22, top board 21 and base plate 23, and top board 21 and base plate 23 extend in the same way from the two ends up and down of sidewall 22 respectively, and the ora terminalis of base plate 23 and top board 21 is in order to clamping light guide board 4.Wherein sidewall 22, top board 21 and base plate 23 setting that is one of the forming.Lampshade 2 is preferably by the panel-bending of plastic material and makes, but in different embodiments, can also make with shoot mode by plastics.And, the top board 21 of lampshade 2 and the length of base plate 23 can be identical also can be inequality, person skilled can be adjusted length, ratio, material and the configuration of top board 21 and base plate 23 according to actual demand.In better embodiment, the length of top board 21 and base plate 23 is extended regional area with the exiting surface 42 of containing LGP 4 at least and the side relative with exiting surface 42 by the both sides of lampshade 2, for example: adjust the regional area that top board 21 is contained the exiting surface 42 of LGP 2, can reach to omit and paste the shading rubber belt or the step of spraying paint, to reduce the effect that edge light leak and processing procedure are simplified.In other embodiments, the side that the bottom surface that base plate 23 may extend to whole LGP 4 is promptly relative with exiting surface 42, and base plate 23 is arranged to have reflective surface will, thereby base plate 23 can replace reflector plate (not illustrating) and improve the light source utilization rate, reaches to reduce cost and purpose that processing procedure is simplified.In the better embodiment, the top board 21 of lampshade 2 and base plate 23 clamping light guide boards 4 make the not displacement or the skew easily of relative position of LGP 4 and lampshade 2.Because the light-emitting area 31 of light emitting diode 3 can be positioned at lampshade with the part that the incidence surface 41 of LGP 4 joins, in 2, the light leak problem that therefore can avoid liquid crystal indicator when being subjected to torsion, to cause LGP 4 to produce with luminescence component 8 dislocation.On the other hand, because lampshade 2 is adjusted relative position with LGP 4 by the mode of clamping, make the light-emitting area 31 that the incidence surface 41 of LGP 4 can more close light emitting diode 3.
In addition, module 10 backlight also comprises the reflecting layer (not shown), is arranged at the inwall of lampshade 2, and the light of reflection luminescence component 8 generations, to increase the utilization ratio of light.The reflecting layer is the inwall that is formed at sidewall 22, top board 21 and base plate 23 in the present embodiment, but also can only be formed on one of them.The base plate 23 of lampshade 2 can be in order to replace reflector plate (not illustrating).In addition, the reflecting layer can utilize the light reflection material that adds to form, and for example is coated with the reflectivity material, attaches the reflectance coating plating; And if the materials of lampshade 2 itself are when being the tool light reflectance properties, also can be directly with inner face own as the reflecting layer.At this only is for example, but the invention is not restricted to this, and person skilled also can be adjusted the generation type of reflective surface will according to actual demand.
Other sees also Fig. 4, Figure 4 shows that the schematic diagram according to second embodiment of module backlight of the present invention.In the present embodiment, same, module 1 ' backlight comprises lampshade 2 ', a plurality of luminescence component, LGP 4 and at least one support member.Each luminescence component comprises a plurality of light emitting diodes 3 and circuit board 5, and these light emitting diodes 3 electrically are arranged on the circuit board 5.In the present embodiment, support member 6 ', 7 ' is to insert lampshade 2 ' from sidewall 22 ', promptly support member 6 ', 7 ' and the sidewall of lampshade 2 ' be separable.And except the setting of support member, other structures of module 1 ' backlight all with first embodiment in the structural similarity of module backlight 1, thereby be not described in detail in this.
See also Fig. 5, Fig. 5 is the schematic diagram of display unit 20 of the present invention.Display unit 20 comprises display floater 9 and aforesaid module backlight 1, and display floater 9 is arranged on the module 1 backlight.Module 1 backlight provides display floater 9 needed area sources.And display unit 20 comprises liquid crystal indicator, comprises the LCD Panel etc. of LCD, mobile phone and digital camera of LCD TV, PC and the kneetop computer of family expenses.
In addition, display unit 20 has been drawn together the glue frame, and the glue frame is located luminescence component 8 and LGP 4 around the outside of luminescence component 8 and LGP 4, and luminescence component 8 is then between glue frame and LGP 4.
