Abstract
The utility model provides a backlight module which is lightweight in structure and convenient to mount and a keyboard using the backlight module. The backlight module comprises a light guide board and a circuit board, wherein the light guide board is provided with a light-emitting element, and the light guide board and the circuit board are sequentially stacked from top to bottom. Light emitted by the light-emitting element can be uniformly upwards irradiated through the guide of the light guide board. The backlight module provided by the utility model eliminates a light screen and a reflecting sheet, thereby saving materials, reducing the thickness of the whole and the assembly process steps, reducing the cost and being suitable for ultra-thin notebook computers. The light-emitting keyboard using the backlight module comprises keys and a bottom board, wherein the keys are mounted on the bottom board, and the bottom board is mounted above the light guide board of the backlight module. The bottom board can simultaneously realize the effects of mounting the keys and attaching the backlight module. The backlight module and the light-emitting keyboard using the backlight module have the advantages of simple structure, convenience in assembly, low cost and thin thickness, and are suitable for ultra-thin notebook computers.
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 and circuit board, and said LGP is provided with light-emitting component, and said LGP and circuit board are according to from top to bottom sequence stack.
Light that light-emitting component emits is through the conduction of the LGP uniform irradiation that can make progress; Than background technology; The module backlight of the utility model has omitted shadow shield and reflector plate; Therefore save material, reduced the whole thickness and the operation of assembling, reduced cost, be suitable for ultrathin notebook.
Specifically, light-emitting component be provided with following dual mode:
1, the edge of said LGP 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.
2, said LGP has 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.
Above-mentioned two kinds of structures all can provide positioning function in assembling process, and LGP 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 LGP 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.
