Abstract
The utility model discloses a backlight module which is light and handy in structure and convenient for installation, and a keyboard using the backlight module. The backlight module comprises a light guide plate, a reflection sheet and a circuit board; the light guide plate is provided with a light emitting element; and the light guide plate, the reflection sheet and the circuit board are stacked from the top down. The light emitted by the light emitting element can be uniformly irradiated upwards through the guidance of the light guide plate and the reflection of the reflection sheet. In the backlight module, a light screen is saved, so that the material is saved, the whole thickness and the assembling process are decreased and the cost is reduced; and the backlight module is suitable for ultrathin notebooks. The light emitting keyboard using the backlight module comprises keys and a bottom board, wherein the keys are arranged on the bottom board; and the bottom board is arranged above the light guide plate of the backlight module. The bottom board has the functions of mounting the keys and shielding lights. The backlight module and the light emitting backboard are simple in structure, convenient for assembling, low in cost, small in thickness and suitable for ultrathin notebooks.
Description
Technical field
The utility model belongs to electrical equipment manufacturing technology field, specially refers to a kind of and uses the illuminated keyboard of this module backlight.
Background technology
The patent No. is that 201120028615.7 utility model discloses a kind of illuminated keyboard, and this kind illuminated keyboard comprises base plate, a plurality of button and module backlight.A plurality of buttons are arranged on the base plate; Module backlight comprises shadow shield, LGP and reflecting plate.Shadow shield is arranged under the base plate, and LGP is arranged under the shadow shield, and reflecting plate is arranged under the LGP.Shadow shield, LGP and reflecting plate are stacked into the zone line of module backlight.Shadow shield and reflecting plate one of them the edge reflexed and with shadow shield and reflecting plate wherein another is stacked into the fringe region of module backlight, zone line and fringe region are with high.
Though above-mentioned module backlight can make illuminated keyboard produce preferable distribution of light, its thickness is thicker, produces assembling inconvenience, is difficult to be applied on the ultrathin notebook.
The utility model content
The purpose of the utility model is the keyboard that proposes a kind of structure module backlight light and handy, easy for installation and use this module backlight.
The module backlight of the utility model comprises LGP, reflector plate and circuit board, and said LGP is provided with light-emitting component, and said LGP, reflector plate and circuit board are according to from top to bottom sequence stack.
The light that light-emitting component emits is through the conduction of LGP and the reflection of reflector plate; Uniform irradiation can make progress; Than background technology, the module backlight of the utility model has omitted anti-dazzling screen, has therefore saved material, has reduced the whole thickness and the operation of assembling; Reduce cost, be suitable for ultrathin notebook.
Specifically, light-emitting component be provided with following dual mode:
1, the edge of said LGP, reflector plate has recess, and said light-emitting component is arranged at the end face of circuit board, and said light-emitting component is corresponding and be contained in the recess of LGP, reflector plate.
2, said LGP, reflector plate have hole, and said light-emitting component is arranged at the end face of circuit board, and said light-emitting component is corresponding and be contained in the hole of LGP, reflector plate.
Above-mentioned two kinds of structures all can provide positioning function in assembling process, and LGP, reflector plate and light-emitting component can not interfere, and make assembling convenient.
The illuminated keyboard of the module backlight that the use that the utility model proposes is above-mentioned comprises button and base plate, and said button is installed on the base plate, and said base plate is installed on the top of the LGP of module backlight.Base plate plays the effect of button being installed and connecting module backlight simultaneously.
The module backlight of the utility model and use the illuminated keyboard of this module backlight simple in structure, easy to assembly, cost is low, thin thickness is suitable for ultrathin notebook.
