Below in conjunction with accompanying drawing the utility model is elaborated.
Description of drawings
Fig. 1 is the schematic diagram of a kind of illuminated keyboard of the utility model preferred embodiment.
Fig. 2 illustrates the schematic diagram of the single luminous button of Fig. 1.
Fig. 3 and Fig. 4 are respectively the light emitting module of Fig. 2 and the schematic diagram of shadow shield.
Embodiment
Please refer to Fig. 1 and Fig. 2, Fig. 1 is the schematic diagram of a kind of illuminated keyboard of the utility model preferred embodiment, and Fig. 2 illustrates the schematic diagram of the single luminous button of Fig. 1.Illuminated keyboard 1 comprises circuit board 10, a plurality of luminous button, and luminous button comprises light emitting module 12, a plurality of keycap 14 and shadow shield 16.Light emitting module 12 electrically connects circuit board 10, and comprises a plurality of crystal grain, and wherein, these crystal grain are in order to send at least two kinds of different color lights, and these coloured light are mixed into mixed light.Keycap 14 is arranged on the light emitting module 12, and wherein, keycap 14 respectively has at least one transmittance section 18, and transmittance section 18 counterpart crystal grain are provided with.Shadow shield 16 is arranged between light emitting module 12 and the cluster keycap 14, and has a plurality of coloring printing ink layers 20.Coloring printing ink layer 20 is compensated for as the target coloured light that color is comparable to this mixed light in order to the coloured light with crystal grain between crystal grain and transmittance section 18.
And please refer to Fig. 3 and Fig. 4, Fig. 3 and Fig. 4 are respectively the light emitting module of Fig. 2 and the schematic diagram of shadow shield.As shown in Figure 3, light emitting module 12 comprises blue-light-emitting crystal grain 12B, green luminescence crystal grain 12G and red light-emitting crystal grain 12R.These crystal grain are arranged in a straight line, and mixed light is a white light.Because the 18 (see figure 2) positions, transmittance section of the corresponding keycap 14 of blue light emitting crystal grain 12B, when blue light emitting crystal grain 12B is luminous, can make transmittance section 18 blue partially, therefore, as shown in Figure 4, preferably, the coloring printing ink layer 20 of corresponding blue light emitting crystal grain 12B is the Yellow ink layer, is the mixed light that is similar to white light with the compensation blue light.
In addition, the part of corresponding green luminescence crystal grain 12G and red light-emitting crystal grain 12R, preferablely cover with other coloring printing ink layer 22, this coloring printing ink layer 22 can be black ink layer, to cover in green glow and the ruddiness that green luminescence crystal grain 12G and red light-emitting crystal grain 12R are sent, avoid red-green glow to sneak into transmittance section 18.These ink laies are formed on transparent base layer 24 (see figure 2)s to constitute this shadow shield 16.
Though the light emitting module 12 of present embodiment is to comprise that blue-light-emitting crystal grain 12B, green luminescence crystal grain 12G and red light-emitting crystal grain 12R are example, so to be not limited thereto that also not limiting mixed light is white light.The visual coloured light that will blend together of light emitting module 12 ends goes to determine the formation of crystal grain, and light emitting module 12 can be made of the crystal grain of other color in fact.In addition, coloring printing ink layer 20 and 22 also is not defined as yellow and black ink layer, and its visual pairing crystal grain goes to determine the color of coloring printing ink layer 20 and 22, to compensate the coloured light that crystal grain sends.
The disclosed luminous button of the foregoing description of the present utility model and use its illuminated keyboard, the color of looking luminescent grain is removed the coloring printing ink layer of appropriate mix, coloured light with timely compensation crystal grain produces required mixed light effect, thus, the color of illuminated keyboard is uniformity more, can promote the texture of illuminated keyboard in fact.
By the detailed description of above preferable embodiment, hope can be known description feature of the present utility model and spirit more, and is not to come claim scope of the present utility model is limited with above-mentioned disclosed preferable embodiment.On the contrary, its objective is that hope can contain in the scope of the claim that is arranged in the desire application of the utility model institute of various changes and tool equality.
