Fig. 2 is that of this present embodiment uses state reference map, and the relation of this illuminating module and multiple operating keys is described.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Consult Fig. 1, Fig. 2, a preferred embodiment of the utility model illuminating module 10 can produce light, and by multiple operating keys 11 of ray cast to illuminated keyboard, described operating key 11 can be same color, also can be according to controlling the different color of the different employings of function, each operating key 11 has at least one and is used for showing special symbol or digital light-emitting zone 111.
And this illuminating module 10 comprises: a slice light guide plate 2, one are combined in printing opacity unit in this light guide plate 23, one with mode of printing and are combined in bottom floor units 4 in this light guide plate 2 and one with mode of printing and can produce light and the luminescence unit 5 to this light guide plate 2 by ray cast.This printing opacity unit 3 and this bottom floor units 4 lay respectively at the opposition side of this light guide plate 2.
This light guide plate 2 of the present embodiment is made for light transmissive material, in this preferred embodiment, this light guide plate 2 adopts the resin of refractive index 1.45 to make, and the exiting surface 21, that this light guide plate 2 comprises a described operating key 11 of vicinity and this exiting surface be parallel bottom surface 22 and the incidence surface 24 that at least one runs through this exiting surface 21 and this bottom surface 22 and defines a perforation 23 Shang Xia 21.
And this printing opacity unit 3 is combined on the exiting surface 21 of this light guide plate 2 in the mode of printing, and comprise a first printing opacity refracting layer 31 on the exiting surface 21 that is combined in this light guide plate 2 and one and first of these the first printing opacity refracting layer 31 combinations assembly 32 that is in the light.This first printing opacity refracting layer 31 adopts refractive index to make lower than the material of the refractive index of this light guide plate 2, is to adopt the transparent ink that refractive index is 1.2 in this preferred embodiment.And this first assembly 32 that is in the light has the transmission region 323 of first reflector 321 of being made up of white transparent ink, first light shield layer 322 of being made up of black ink and the corresponding described operating key 11 of multiple difference.Each transmission region 323 has a perforation 324 that simultaneously runs through this first reflector 321 and this first light shield layer 322, an and colour developing piece 325 that is positioned at this perforation 324, in this preferred embodiment, described colour developing piece 325 is combined on this first printing opacity refracting layer 31 in the mode of printing, and adopt blending to have the printing opacity ink of pigment, the ink colors of the colour developing piece 325 of above-mentioned transmission region 323 can be identical, also can adopt the ink of different colours, adopt the ink of different colours to manufacture the colour developing piece 325 of described transmission region 323, can change the color of the light that projects described operating key 11, make the illuminated keyboard that this illuminating module 10 is installed produce abundant color change.
But in design, the present embodiment is as long as first be in the light on assembly 32 described transmission region 323 is set at this, and allow part light can penetrate this first reflector 321 and this first light shield layer 322, and project described operating key 11, just can reach and allow the luminous object of described operating key 11, therefore the utility model is not in design to have described colour developing piece 325 as necessary.But because can utilizing mode of printing, the piece 325 that develops the color described in the present embodiment is combined on this first printing opacity refracting layer 31, therefore the present embodiment can change easily by the color of the coloured light of described colour developing piece 325, make the operating key 11 of this illuminated keyboard produce the coloured light of different colours.
This bottom floor units 4 of the present embodiment is combined in the bottom surface 22 of this light guide plate 2 in the mode of printing, and comprises that the second printing opacity refracting layer 41 of a bottom surface 22 that is combined in this light guide plate 2 and one are combined in second of these the second printing opacity refracting layer 41 belows assembly 42 that is in the light.This second assembly 42 that is in the light has second reflector 421 that is combined in these the second printing opacity refracting layer 41 bottoms and one and is combined in the second light shield layer 422 of these 421 bottoms, the second reflector.This second printing opacity refracting layer 41 is also to adopt the transparent ink of refractive index 1.2 to manufacture, and this second reflector 421 is the transparent ink of white, and this second light shield layer 422 is black ink.
And comprising illuminating part 51 at least one perforation 23 that is arranged on this light guide plate 2 and one and this illuminating part 51, this luminescence unit 5 is electrically connected and is arranged on the circuit board 52 of these bottom floor units 4 belows.
This illuminating module 10 of the present embodiment during fabrication, take this light guide plate 2 as basis, and sequentially print this second printing opacity refracting layer 41 in the bottom surface 22 of this light guide plate 2 with mode of printing, this second reflector 421 and this second light shield layer 422, just can complete the making of this bottom floor units 4, and on the exiting surface 21 of this light guide plate 2, print this first printing opacity refracting layer 31, this first reflector 321, this first light shield layer 322 and described colour developing piece 325, just can complete the manufacture of this printing opacity unit 3, this luminescence unit 5 is finally installed, just can complete the manufacture of this illuminating module 10 of the present embodiment.Because the printing opacity unit 3 of the present embodiment and this bottom floor units 4 are all stacked in the opposition side of this light guide plate 2 in the mode of printing, therefore illuminating module is more in the past simple, fast really on manufacturing for the utility model.
On the other hand, the utility model prints respectively this first printing opacity refracting layer 31 of moulding and this second printing opacity refracting layer 41 on the exiting surface 21 of this light guide plate 2 and bottom surface 22, and the refractive index that makes described the first printing opacity refracting layer 31 and the second printing opacity refracting layer 41 approaches the refractive index of air, namely be less than the refractive index of this light guide plate 2, previous designs can allow and enter the light of this light guide plate 2, when by described the first printing opacity refracting layer 31 and the second printing opacity refracting layer 41, produce larger refraction angle, make the light past direction transmission away from this illuminating part 51 smoothly.Because colour developing piece 325 described in the utility model is also that the ink with pigment is made, therefore the utility model can be by the color of the pigment of the described colour developing piece 325 of change, and change by the color of the light of described colour developing piece 325, make the light of various different colours can project described operating key 11, to produce colored light, because the utility model is in the time changing the demonstration light of described operating key 11, also be that the mode of printing just can be reached, therefore the utility model is in the time that manufacture has the illuminating module 10 of colored light, its processing procedure is also very simple, quick.
