Detailed description of the invention
First, as shown in Figures 1 to 5, preferred embodiment of the present utility model, only these embodiments are only for instructions, the restriction not by this structure in patent application.
The described structure that this is avoided light source to leak outside, is the utility model first embodiment as shown in FIG. 1 to 3, comprises:
Reflecting layer 10 and once reflecting layer 20 on one, and on this reflecting layer 10 relative with this lower reflecting layer about 20 paste be incorporated in central authorities form an accommodation space 60, the accommodating light guide plate 40 of this accommodation space 60, and this accommodation space 60 is coated with a light shield layer 30 relative to the side place of this light guide plate 40, and this light shield layer 30 is close to this light guide plate 40, this light guide plate 40 is provided with several LED accommodation space 41;
At least one luminescence unit 50, be laid in this lower reflecting layer 20 times, and respectively this luminescence unit 50 comprises an illuminating circuit 51 and number LED52, respectively this LED52 is through being placed in respectively in this LED accommodation space 41 after several open-works 21 in this lower reflecting layer 20, make in light source incidence to each this light guide plate 40, incident light source recycles the light source conduction pathway that on this, reflecting layer 10 and this lower reflecting layer 20 are formed and transmits light; Respectively the structure of this luminescence unit 50 is only for instructions, the restriction not by this structure in patent application.Such as, this luminescence unit 50 also can be laid in this light guide plate 40 times, respectively this LED52 is placed in respectively in this LED accommodation space 41, or this luminescence unit 50 also can directly be embedded on inside this lower reflecting layer 20, lay in this lower reflecting layer 20 each this LED52 must this illuminating circuit 51, respectively this LED52 is placed in respectively in this LED accommodation space 41.
Wherein, this light shield layer 30 is dark oil layer of ink or low-refraction ink layer, and scope is more than or equal to light guide plate side;
Wherein, on this, reflecting layer 10 is provided with several transparent area 11, and respectively this transparent area 11 corresponds to for luminous position, and as shown in Figure 2, respectively this transparent area 11 can be hole, and as shown in Figure 4, respectively this transparent area 11 can be a transmission region;
Wherein, respectively this light guide plate 40 correspondence respectively this transparent area 11 position and be laid with several reflector space 42 in each this light guide plate 40 lower surface, respectively this reflector space 42 makes light conduction direction change, and is projected to the position of respectively this transparent area 11.
Wherein, on this, reflecting layer 10 and this lower reflecting layer 20 form reflecting layer 10 and this lower reflecting layer 20 on this after being turned down by a slice reflecting layer, on this, reflecting layer 10 and this lower reflecting layer 20 fit together again, and this light guide plate coated 40 in this between reflecting layer 10 and this lower reflecting layer 20, on this, reflecting layer 10 and this lower reflecting layer 20 are opaque reflecting layer, and on this, reflecting layer 10 and this lower reflecting layer 20 can be white, silver color or gray reflective layer;
As Fig. 4 ~ Figure 5 shows that the utility model second embodiment, second embodiment is consistent haply with the component of the first embodiment, its difference to be only on this that reflecting layer 10 and this lower reflecting layer 20 are formed by two reflecting layer, on this, reflecting layer 10 and this lower reflecting layer 20 fit together, and this light guide plate coated 40 in this between reflecting layer 10 and this lower reflecting layer 20;
By above structure, respectively this luminescence unit 50 of the present utility model makes in light source incidence to each this light guide plate 40, incident light source recycles the light source conduction pathway that on this, reflecting layer 10 and this lower reflecting layer 20 are formed and transmits light, and be transmitted to the position that light source is upwards projected to wish luminescence by respectively this transparent area 11, also therefore light can spill from this light guide plate 40 side, this accommodation space 60 formed of fitting because the lower reflecting layer of reflecting layer on this 10 and this about 20 is relative is coated with ink relative to the side place of this light guide plate 40, when light source is delivered to herein, ink is that black has the effect intercepting light source and flow out, except light source can be avoided to leak outside, make shaded effect better, also light source can be made to rest on this light guide plate 40 internal recovering recycling, to highlight, make shaded effect better, mode like this can solve 3C Product periphery easily the light evil of letting out light and causing, inaesthetic problem.
In sum, the utility model has reached breakthrough structural design really, and there is the author content of improvement, can reach again the usability in industry and progressive, and the utility model does not see any publication simultaneously, also have a novelty, to be correlated with the regulation of law when meeting Patent Law, whence proposes new patent application in accordance with the law, and earnestly ask an ancient unit of weight office juror and authorize legal monopoly power, most sense is prayed.
Only the above, be only a preferred embodiment of the present utility model, when can not with restriction the utility model implement scope; Namely the equalization change generally done according to the utility model claim with modify, all should still belong in scope that the utility model patent contains.
