Abstract
The utility model discloses a light guiding sheet assembly for a keyboard. The light guiding sheet assembly comprises a substrate and a lighting device, and the keyboard comprises keys, wherein recessed screen dots corresponding to the keys are casted on the upper surface of the substrate, and the lighting device is arranged under the substrate. The utility model further discloses a keyboard employing the light guiding sheet assembly. When the keyboard employs such a structure, the screen dots on the substrate reflect the light from the lighting device, so that the keyboard emits light uniformly.
Description
Technical field
The utility model relates to the accessory of electronic product, and particularly a kind of light guide sheet assembly for keyboard light-emitting device, also relates to a kind of keyboard with this light guide sheet assembly.
Background technology
Along with scientific and technological development, electronic product becomes an indispensable part in people's life.In prior art, with the keyboard inner side of the electronic product of keyboard, be typically provided with for illuminating the light source of button, thereby be convenient to user when insufficient light, still the correct sign on key range.
And a plurality of LED lamps of the common installation in keyboard of the prior art inner side are realized illuminating of keyboard, this structure is comparatively complicated, and distribution of light is inhomogeneous.
Utility model content
In order to solve backlighting device for keypad complex structure of the prior art, the defect that distribution of light is inhomogeneous, the utility model proposes a kind of novel light guide sheet assembly, comprise substrate and light-emitting device, described keyboard comprises button, the upper surface die casting of described substrate has pocketed site, and described site correspondence the position distribution of described button, and described light-emitting device is arranged in described substrate below.
Adopt this structure, the site distributing on substrate can be to coming the light of selfluminous device to reflect, thereby make keyboard uniformly light-emitting.In addition, die casting pocketed site processing cost is out low, and technological process is comparatively simple.
As a kind of embodiment, the size of described site is directly proportional to the distance between described light-emitting device to this site.That is, from light source more away from, site is larger, from light source more close to, site is relatively less.Site is larger, and the light of reflection is just more, thereby guarantees that light guide sheet assembly is provided uniformity of light by keyboard.
Preferably, described site is shaped as circle or polygon.
Particularly, described light-emitting device is light emitting diode.
Preferably, the quantity of described light emitting diode is one or more.
The utility model also proposes a kind of keyboard, comprises foregoing light guide sheet assembly.
Light-emitting device can be positioned at the optional position of light guide sheet top.
Especially, at the upper surface of substrate, be still provided with reflector, this reflector is vacated in the position of button and site.So both facilitate bright dipping, also reduced to greatest extent the loss of light in communication process.
The utility model also relates to a kind of keyboard that comprises foregoing light guide plate assembly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the light guide sheet assembly of an embodiment of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, provide the utility model embodiment, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model proposes a kind of novel light guide sheet assembly, comprise substrate 11 and light-emitting device 12, described keyboard comprises button (not shown), the upper surface die casting of described substrate has pocketed site 13, described site 13 correspondences the position distribution of described button, and described light-emitting device 12 is arranged in described substrate below.
Adopt this structure, the site distributing on substrate can be to coming the light of selfluminous device to reflect, thereby make keyboard uniformly light-emitting.In addition, die casting pocketed site processing cost is out low, and technological process is comparatively simple.
Fig. 1 preferred embodiment shows as a kind of, and the size of site 13 is directly proportional to the distance between described light-emitting device to this site.That is, from light source more away from, site is larger, from light source more close to, site is relatively less.Site is larger, and the light of reflection is just more, thereby guarantees that light guide sheet assembly is provided uniformity of light by keyboard.
Preferably, described site is shaped as circle.What certainly, the shape of site can also be according to button on keyboard need to be arranged to triangle, quadrangle or pentagon.
Particularly, described light-emitting device is light emitting diode.The quantity of described light emitting diode can be one, can be also a plurality of.
The utility model also proposes a kind of keyboard, comprises foregoing light guide sheet assembly.
Light-emitting device can be positioned at the optional position of light guide sheet top.
Also be provided with reflector with upper surface of base plate (being exiting surface), this reflector is vacated in the position of keyboard and site, has both facilitated bright dipping, also reduces to greatest extent the loss of light in communication process.
By the mode of exemplary embodiment, the utility model is carried out to exemplary explanation above, but the utility model is not limited to this.Be construed as, in the situation that not departing from design of the present utility model, operation principle, the equipment in above embodiment, material, install and use other replacement or the equivalent processes that can know by the art personnel and replace.The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
