Fig. 1 to Fig. 6 shows the structural schematic diagram of composite light guiding device provided in an embodiment of the present invention.
Please refer to Fig. 4 and Fig. 5, a kind of composite light guiding device, including light conducting plate body 10, the one side of light conducting plate body 10
It is provided with for light to be carried out irreflexive guide-lighting micro-structure 13, the opposite another side of light conducting plate body 10 is equipped with for inciting somebody to action
The light-emitting surface 11 that light projects, the side of light conducting plate body 10 are equipped with the incidence surface 12 for importing light, specifically, guide-lighting
Micro-structure 13 is arranged in the bottom surface of light conducting plate body 10, and correspondingly, light-emitting surface 11 is set to the top surface of light conducting plate body 10, enters light
The one side or the multi-lateral in light conducting plate body 10 can be arranged in face 12, for light to be incident in light conducting plate body 10, light guide plate
The one side that ontology 10 is equipped with guide-lighting micro-structure 13 is equipped with complex reflex layer 2, and complex reflex layer 2 includes from inside to outside (away from leaded light
The direction of plate ontology 10 is outer) low-index layer 20, the first optics adhering layer 21 and the reflector plate 22 that set gradually.
Referring particularly to Fig. 2 and Fig. 3, if only the first optics adhering layer 21 of setting between light conducting plate body 10 and reflector plate 22,
When there is no low-index layer 20 is arranged, and use conventional first optics adhering layer 21 (with the refraction of the first optics adhering layer 21
For rate is 1.4) when, light leakage phenomena is more serious.Specifically, with the increase of the refractive index of the first optics adhering layer 21, light leakage
Phenomenon gradually becomes serious.Meet total reflection, no light leakage phenomena when the refractive index of the first optics adhering layer 21≤1.1；First
When the refractive index of optics adhering layer 21=1.2, there is light bias；The refractive index of first optics adhering layer 21>When 1.2, light leakage compared with
It is more.So in order to avoid light leakage, the refractive index of the first optics adhering layer 21 need to be less than 1.24, preferably less than 1.1.Market at present
On the refractive index of the first optics adhering layer 21 be all higher than 1.35, temporarily there is no the first optics adhesions that refractive index is less than 1.24
Layer 21, so by 21 adhesion light conducting plate body 10 of the first optics adhering layer and reflector plate 22, light leakage phenomena is inevitable.
And 21 adhesion light conducting plate body 10 of the first optics adhering layer is only used with after reflector plate 22, light is first by entering light
Face 12 is incident in light conducting plate body 10, and the first optics adhering layer 21 is equipped between light conducting plate body 10 and reflector plate 22, due to

Raw total reflection effect, it is more difficult to be transmitted to that side direction of light-emitting surface 11.But it is directly incident on reflector plate 22, and by reflector plate 22
It is directly reflected back in light conducting plate body 10, and is finally projected in 12 side of incidence surface, causing 12 side of incidence surface, nearby light leakage is tight
The problem of weight.
Therefore low-index layer 20, and the folding of low-index layer 20 need to be set between reflector plate 22 and light conducting plate body 10
The refractive index that rate layer is less than light conducting plate body 10 is penetrated, by the way that low-index layer 20 is arranged it is possible to prevente effectively from light is towards incidence surface
12 that side are transmitted, and wherein low-index layer 20 is connect with light conducting plate body 10.With specific reference to Fig. 5, with the first optics adhering layer
It, can be to avoid light leakage for 21 refractive index is 1.4.
Composite light guiding device provided by the invention, it is compared with prior art, guide-lighting micro- by being equipped in light conducting plate body 10
The side setting complex reflex layer 2 of structure 13, complex reflex layer 2 include the low-index layer 20 set gradually from inside to outside, the
One optics adhering layer 21 and reflector plate 22, the refractive index of low-index layer 20 are less than the refractive index of light conducting plate body 10, and successively
It fits together, after fitting, intensity, the hardness of composite light guiding device entirety enhance, and during assembling lamps and lanterns, are not necessarily to
The requirement of whole lamp intensity is can reach by the support of backboard, it, only need to be by composite guide compared to existing by way of storehouse, insertion
Electro-optical device is placed into frame, simplifies assembly technology and reduces material cost and meets ultrathin design, and due to reflector plate 22
It is to avoid reflector plate 22 with face process for pressing by the first optics adhering layer 21 stress release is uneven when expanding with heat and contract with cold, makes
It is heaved at part so that light-out effect is preferable.
