Description

Illuminated keyboard

Technical field

The utility model relates to a kind of illuminated keyboard, particularly reference and a kind ofly constitutes the luminescence unit of a keyboard by thin layer, aluminum layer, luminous composite bed, makes integral thickness more frivolous by this luminous composite bed, more convenient saving cost in the manufacturing.

Background technology

Existing illuminated keyboard as shown in Figure 1, be to be provided with a luminescence unit 3 in keyboard unit 1 bottom of a keyboard, this luminescence unit 3 is to be provided with a flexible circuit flaggy 31 in a thin layer 30 bottom surfaces 300, flexible circuit flaggy 31 bottom surfaces 310 are provided with an aluminum layer 32, aluminum layer 32 bottom surfaces 320 are provided with a backlight layer 33, when backlight layer 33 is luminous that light is luminous via keyboard unit 1 each button below projection keyboard of sening as an envoy to by the space of aluminum layer 32, make things convenient for the user still can operate freely in the dark place of light, but, the existing illuminated keyboard of this kind, be two kinds of soft layers (flexible circuit flaggy 31 and backlight layer 33) to be separated and come by rigid aluminum layer 32, its thickness can't be gone more lightening again, make only limited the reaching in this kind limit of thickness of illuminated keyboard, thickness can't be gone reduction again, therefore, how to conceive produce a kind of can be more lightening, making in the manufacturing more easyly, more save cost, is one can make the further problem of design improvement.

The utility model content

Fundamental purpose of the present utility model is to provide a kind of luminescence unit that is constituted a keyboard by thin layer, aluminum layer, luminous composite bed, wherein this luminous composite bed is to be formed by flexible circuit flaggy, separation layer and a module backlight institute integration, makes and makes more simple also cost-effective illuminated keyboard.

The utility model illuminated keyboard, include a keyboard unit and and be located at the luminescence unit of keyboard unit bottom, this luminescence unit is to be provided with aluminum layer in a thin layer bottom surface, this aluminum layer bottom surface then further is provided with a luminous composite bed that is made of module backlight, separation layer and flexible circuit flaggy, make integral thickness more frivolous by this luminous composite bed, more convenient and saving cost in the manufacturing.Module backlight appropriate position also is provided with at least one accommodation space, and is ccontaining for luminophor.

The effect of the utility model illuminated keyboard is to make the luminescence unit thickness of an illuminated keyboard more lightening, and the manufacturing assembling is gone up more convenient, and saves cost.

Description of drawings

Fig. 1 be existing illuminated keyboard vertically analyse and observe simple synoptic diagram.

Fig. 2 is vertical cross-sectional schematic that the utility model illuminated keyboard corresponding diagram 1 is vertically analysed and observe the position.

Fig. 3 is the detail structure partial exploded view of the luminous composite bed of Fig. 2.

Embodiment

Below in conjunction with drawings and Examples the utility model is elaborated:

Before the utility model detailed explanation, about the keyboard unit 1 of the keyboard unit 1 of illuminated keyboard and existing illuminated keyboard identical, so use identical member numbering, and belong to knownly, make detailed explanation no longer in addition in this for member, assembling and the start thereof of thin portion.

Fig. 2, Fig. 3, it is the preferred embodiment of the utility model illuminated keyboard, include a keyboard unit 1 and and be located at the luminescence unit 2 of keyboard unit 1 bottom 10, this luminescence unit 2 is to be provided with aluminum layer 32 in a thin layer 30 bottom surfaces, aluminum layer 32 bottom surfaces are provided with a luminous composite bed 23 that is made of module 21 backlight, separation layer 210 and flexible circuit flaggy 22, modularity thin layer by 23 integrations one-tenth of this luminous composite bed, make the manufacturing assembling go up more convenient, and then the saving cost, be described in more detail as the back:

Keyboard unit 1, thin layer 30, aluminum layer 32 are existing member, and wherein this keyboard unit 1 has most buttons 10, and each button 10 is the made light-permeable of transparent material, and corresponding each button below is provided with emptying aperture.

Cooperate Fig. 3 again, this luminous composite bed 23, from top to bottom be flexible circuit flaggy 22 in regular turn, separation layer 210 (Spacer), and module 21 backlight, wherein the upper surface of flexible circuit flaggy 22 is that the first resistance light thin layer 220 is set, this first resistance light thin layer 220 is constituted by lighttight dark coating, its lower surface then is provided with first reflector layer 221 (white high gloss), is constituted but this reflector layer 221 is coatings by reflection ray; Moreover the lower surface of this separation layer 210 also is provided with one second reflector layer 211, and material is with first reflector layer 221; Person in addition, this module 21 backlight is made of with reflection horizon 214 (Reflector) an optical waveguide layer 212 (Light guide plate), scattering layer 213 (Diffuser), wherein the lower surface in reflection horizon 214 and be provided with one second and hinder light thin layer 215; In addition, one accommodation space 216 is to be arranged at the place, locus that is defined in optical waveguide layer 212, scattering layer 213 and reflection horizon 214, each accommodation space 216 is provided with a luminophor 217, what deserves to be explained is, wherein scattering layer 213 is most the light guide ink points of at random or uniformly-spaced arranging 2130 at present embodiment, 217 of luminophors are light emitting diode (Led) wick, and this luminophor 217 also is electrically connected on the thin base 218 (FPC).

As Fig. 3, when luminophor 217 energisings, light 2170 is in the guide lighting channel that second reflector layer 211 and second optical waveguide layer 212, scattering layer 213, the reflection horizon 214 that hinders 215 of light thin layers of separation layer 210 are defined, the scattering that light is average is sent to the spatial dimension place of keyboard, produce splendid brightness, and project button 10 via the emptying aperture of keyboard unit 1 each button 10 below, make integral keyboard unit 1 luminous.

The utility model is the flexible circuit flaggy and the module backlight that is positioned under it that is positioned in the luminescence unit with existing keyboard on the aluminum layer, integration becomes the luminous composite bed 23 of one deck and is located at the aluminum layer bottom surface, test factually, existing flexible circuit board layer thickness 0.3mm, module thickness backlight is 1mm, because be positioned on the aluminum layer 32, the upper/lower positions place is 1.3mm with the gross thickness, and luminous composite bed 23 thickness of this case may be made in 0.6mm, compared with the known 0.7mm that reduced, still do not make the thickness of luminescence unit, reduce to the more slimming that is over half, the consumptive material and the cost of manufacturing are more saved, can be reached above-described purpose really.
