The inclination incidence surface 2011a of inclined-plane 2031a and light guide plate 201a has formed it into gapless closed structure；Light source module 10a
Lower end lead angle inclined-plane 1013a it is close together in light guide plate 201a inclination incidence surface 2011a and reflecting layer 202a inclined surface
2021a has formed it into gapless closed structure.Since light source module 10a and light guide module 20a can be complete closely sealed and continuously
Gap, therefore light-emitting component 102a needn't be close to light guide plate 201a or change the direction of its light extraction, produced by light-emitting component 102a
Light when entering light guide plate 201a by inclination incidence surface 2011a, other than occurring the case where not having light leakage, inclined design
The area that incidence surface 2011a also increases incidence surface light receiver simultaneously is tilted, shining for backing structure so can be effectively promoted
Brightness.
Please continue to refer to shown in Fig. 2A to Fig. 2 B, Fig. 2A to 2B is the backing structure of second embodiment of the invention.Such as Fig. 2A
It is shown, wherein the light source module 10b of backing structure, light guide module 20b and each element of bottom plate 30b and the light source module of Figure 1A
Each element function of 10a, light guide module 20a and bottom plate 30a are identical, just repeat no more herein.Only, difference is in light source die
The angle α of the bottom surface 103b of the first inclined surface 101b and light source module 10b of block 10b are more than 90 degree；And by light shield layer 203b
Inclined surface 2031b, light guide plate 201b the inclined surface 2021b three of inclination incidence surface 2011b and reflecting layer 202b constituted
Its angle β with the bottom surface 2022b of light guide module 20b of the second coplanar inclined surface CP is less than 90 degree.Due to light guide module
The angle β of 20b is less than 90 degree, therefore in assembling process, first by the reflecting layer 202b of light guide module 20b and light guide plate 201b
It is set on bottom plate 30b, then light source module 10b is installed in the side of reflecting layer 202b and light guide plate 201b, be finally arranged
Light shield layer 203b and the top for being covered in light source module 10b and light guide plate 201b.Due to the angle β and light source of light guide module 20b
Both angle αs of module 10b summation is also equal to 180 degree, therefore light source module 10b can pass through the first inclined surface 101b and guide-lighting mould
The second inclined surface CP of block 20b is mutually chimeric and constitutes closed structure as shown in Figure 2 B.
Compared to the prior art, light source module of the invention and light guide module have the inclined surface of angled complimentary so that light source
Module can be complete closely sealed with light guide module and generate gap, efficiently avoids the generation of light leak situation.In addition, passing through inclination
The design in face, in addition to it can promote the brightness of back light, light source module can be assembled more simply with light guide module, therefore can letter
Change the assembly program of backing structure to promote the efficiency of its assembling；Therefore the invention of a present invention actually great industrial value.
The present invention as be familiar with this skill personage Ren Shi craftsman think and be it is all as modify, so neither take off such as attached claim institute
It is intended to protect.
