Hereinafter, come to describe in more detail exemplary embodiment of the present invention with reference to the accompanying drawings.
Fig. 1 illustrates the decomposition diagram of module backlight according to an exemplary embodiment of the present invention.
With reference to Fig. 1, module 100 backlight comprises storage container 200, a plurality of lamp 300, diffusing panel 350 and lamp-fixing member 400.
Diffusing panel 350 is arranged on the top of lamp 300.The light diffusion that is provided by lamp 300 is provided diffusing panel 350, to improve the homogeneity of brightness.Diffusing panel 350 can have plate shape shape.In addition, diffusing panel 350 is separated predetermined distance with lamp 300.
Diffusing panel 350 is formed by optically transparent material.Diffusing panel 350 also can be formed by the light diffusion material, with diffused light.For example, diffusing panel 350 can be formed by the polymethylmethacrylate (PMMA) as optically transparent material.
Lamp-fixing member 400 is installed on the base plate 210, is used for fixing lamp 300.When the length of lamp 300 increased, lamp 300 can distortion or sagging.Therefore, lamp-fixing member 400 stably supports the middle part of lamp 300, and can prevent the distortion of lamp 300 and sagging.
The number of lamp-fixing member 400 can be determined by the number of lamp 300.For example, each of lamp-fixing member 400 can be fixed four lamps 300, but is not limited to this.
When the number of lamp-fixing member 400 during greater than, each lamp-fixing member 400 can be arranged with zigzag along the direction longitudinally that is substantially perpendicular to lamp 300 and be provided with.When each lamp-fixing member 400 is provided with by a direction, can produce defective, for example, can form concealed wire corresponding to lamp-fixing member 400.So, can lamp-fixing member 400 be set with zigzag, thereby can prevent the concealed wire defective.
Each of lamp 300 is fixing by a lamp-fixing member 400.Yet when lamp 300 was oversize, each of lamp 300 can be fixing by the lamp-fixing member 400 more than.Each of lamp-fixing member can be along the predetermined distance that vertically is spaced apart from each other of lamp 300.In this case, lamp-fixing member 400 can be arranged with zigzag along the direction longitudinally that is substantially perpendicular to lamp 300 and be provided with.
Fig. 2 is the amplification partial plan layout that the diffusing panel 350 in the storage container 200 that is contained among Fig. 1 is shown.
See figures.1.and.2, diffusing panel 350 is received container 200 and side form 370 supports.Specifically, the sidewall 220 that diffusing panel 350 and first vertical substantially parallel side lamp 300 are received container 200 supports, being supported by side form 370 with this second vertical side of first side group of diffusing panel 350.Thereby the accommodated position of diffusing panel 350 is received the second diffusing panel leader, 372 guiding of the first diffusing panel leader 222 and the side form 370 of container 200.
Heat and moisture can make diffusing panel 350 distortion easily.Therefore, diffusing panel 350 is received, corresponding to the degree of diffusing panel 350 distortion diffusing panel 350 and the first diffusing panel leader 222 and the second diffusing panel leader 372 are separated predetermined distance.For example, diffusing panel 350 can separate about 1.5mm with the first diffusing panel leader 222 and the second diffusing panel leader 372.The second diffusing panel leader 372 can comprise fixedly protuberance of sheet, with fixed optics sheet 360.
Fig. 3 is the skeleton view that the lamp-fixing member shown in Fig. 1 is shown, and Fig. 4 is the cut-open view that the lamp-fixing member among Fig. 3 is shown.
With reference to Fig. 3 and Fig. 4, lamp-fixing member 400 comprises main part 410, bolster 420, diffusing panel support section 430 and lamp fixed part 440.
Can adjust the shape of bolster 420, to improve the elasticity of bolster 420.When diffusing panel 350 is contained in the storage container 200, bolster 420 bufferings moving and the sagging power that imposes on diffusing panel support section 430 that forms by diffusing panel 350.As shown in Figure 4, the cross section along vertical intercepting of main part 410 of bolster 420 can have trapezoidal shape basically.In other words, bolster 420 comprises the sidepiece with respect to main part 410 inclinations, and the sidepiece of described inclination engages with main part 410.
Diffusing panel support section 430 can protrude from bolster 420, to support diffusing panel 350.The height of diffusing panel support section 430 can be greater than the height of lamp-fixing member 440.Diffusing panel 350 is big more, and the middle part of diffusing panel 350 is sagging must be low more.So diffusing panel support section 430 can prevent the sagging of diffusing panel 350.In addition, diffusing panel support section 430 keep diffusing panels 350 and the lamp 300 fixed by lamp-fixing member 440 between distance.For example, as shown, diffusing panel support section 430 can have conical in shape.Therefore, when the mobile generation diffusing panel 350 of diffusing panel 350 and the friction between the diffusing panel support section 430, the elasticity of bolster 420 can make described minimise friction.
Lamp-fixing member 430 is formed on the upper surface of main part 410, and supports lamp 300.Lamp-fixing member 440 is protruding upward from main part 410.Lamp-fixing member 440 can have opening portion 442, so that lamp 300 can be inserted in the opening portion 442.
The width of opening portion 442 is determined by the diameter of lamp 300.The width of opening portion 442 is big more, and each of lamp 300 can be inserted in the lamp fixed part 440 easily more.Yet when the width of opening was excessive, each of lamp 300 can break away from lamp fixed part 440 easily.So the width of expectation opening portion 442 can have 80% 90% scope to the diameter of lamp 300 from the diameter of lamp 300.For example, when the diameter of lamp 300 was about 4mm, the width of opening portion 442 can be about 3.3mm.
A plurality of lamp fixed parts 440 are formed on the both sides of bolster 420 discriminably.For example, lamp-fixing member 400 comprises four lamp fixed parts 440 (two sides at bolster 420).Alternatively, lamp-fixing member 400 can comprise the lamp fixed part 440 of various numbers.
Lamp-fixing member 400 also can comprise at least one bound fraction 450, to combine with storage container 200.Bound fraction 450 can be formed on the basal surface of main part 410.The position of bound fraction 450 and number can change.
The base plate 210 of reflecting plate 380 and storage container 200 has the opening corresponding to the bound fraction 450 of lamp-fixing member 400.The opening of bound fraction 450 penetrate through reflective plates 380 and base plate 210, and hook base plate 210.
Fig. 5 is the decomposition diagram that the lamp-fixing member of another exemplary embodiment according to the present invention is shown.
With reference to Fig. 5, lamp-fixing member 500 comprises main part 510, bolster 520, diffusing panel support section 530, lamp fixed part 540 and bound fraction 550.Except that bolster 520, lamp-fixing member 500 is substantially the same with the lamp-fixing member among Fig. 4, and any of remainder of elliptical structure further specified.
Bolster 520 is protruding upward from main part 510.For example, bolster 520 is formed on the middle part of main part 510.Alternatively, a plurality of bolsters 520 can form and vertically separate predetermined distance along main part 510.
Bolster 520 can have resilient shapes, is applied to the power of diffusing panel support section 530 with buffering, and described power is moving and sagging formation by diffusing panel 350.For example, the cross section along vertical intercepting of main part of bolster can have arcuate in shape basically.In addition, diffusing panel support section 530 can have empty structure, to improve elasticity.For example, diffusing panel support section 530 can limit cavity, perhaps is cut open, to improve elasticity.
