Summary of the invention
The purpose of this utility model is to provide a kind of processing procedure simple and easy and the backlight module that can reduce manufacturing cost.
Backlight module of the present utility model, comprises a reflector plate, anti-dazzling screen, a light transmission piece, and a light source.This reflector plate comprises and is multiplely formed at end face and the reflecting medium of upwards projection.This anti-dazzling screen is arranged at the top of this reflector plate, and comprises and multiplely run through up and down respectively and supply the punching that described reflecting medium is corresponding respectively.This light transmission piece is arranged between this reflector plate and this anti-dazzling screen.This light source is arranged at the side of this reflector plate and this anti-dazzling screen, and the light beam sent reflexes to this light transmission piece through described reflecting medium, and penetrates this light transmission piece and outwards penetrate from described punching.
Backlight module of the present utility model, this anti-dazzling screen is high reverse--bias material, and segment beam reflexes to after described reflecting medium through this anti-dazzling screen, then reflexes to this light transmission piece via described reflecting medium, and penetrates this light transmission piece and outwards penetrate from described punching.
Backlight module of the present utility model, this anti-dazzling screen is silver-colored reflector plate.
Backlight module of the present utility model, this light source is light emitting diode.
Backlight module of the present utility model, the thickness of this light transmission piece is no more than 0.2mm.
The beneficial effects of the utility model are: be the end face being formed at this reflector plate by means of described reflecting medium, the light beam of this light source constantly can be reflected between this reflector plate and this anti-dazzling screen, to replace the effect of the light guide plate of existing costliness, and the mode that direct punching adopted by this anti-dazzling screen makes light beam can penetrate from described punching, relatively simple and easy many on processing procedure.
Accompanying drawing explanation
Of the present utility model other feature and effect, clearly present in reference to graphic embodiment, wherein:
Fig. 1 is a section plan, and existing a kind of backlight module is described;
Fig. 2 is a three-dimensional exploded view, and a preferred embodiment of the utility model backlight module is described, omits a light source in figure; And
Fig. 3 is a section plan of this preferred embodiment.
Detailed description of the invention
Consult Fig. 2 and Fig. 3, the preferred embodiment of the utility model backlight module is applicable to a keyboard module (not shown), and comprises a reflector plate 1, anti-dazzling screen 2, light transmission piece 3, and a light source 4.
This reflector plate 1 comprises and is multiplely formed at end face and the reflecting medium 11 of upwards projection.
This anti-dazzling screen 2 is high reverse--bias material, and is arranged at the top of this reflector plate 1, and comprises and multiplely run through up and down respectively and supply the punching 21 of described reflecting medium 11 correspondence respectively.In the present embodiment, this anti-dazzling screen 2 is silver-colored reflector plate.
This light transmission piece 3 is arranged between this reflector plate 1 and this anti-dazzling screen 2, and thickness is no more than 0.2mm.
This light source 4 is arranged at the side of this reflector plate 1 and this anti-dazzling screen 2.In the present embodiment, this light source 4 is light emitting diode.
By means of this anti-dazzling screen 2 made by high reverse--bias material, the light beam that this light source 4 is sent constantly can reflect between this reflector plate 1 and this anti-dazzling screen 2.The downward light beam of part reflexes to this light transmission piece 3 through described reflecting medium 11, and penetrates this light transmission piece 3 and outwards penetrate from described punching 21.And part light beam upwards reflexes to after described reflecting medium 11 through this anti-dazzling screen 2, then reflex to this light transmission piece 3 via described reflecting medium 11, and penetrate this light transmission piece 3 and outwards penetrate from described punching 21.Thus, just can avoid energy loss, and fully reflect the light beam that this light source 4 sends, make the structure gap of this keyboard module (not shown) and can printing opacity place luminous, even if user also can be typewrited easily in dark surrounds.
It is worth mentioning that, the utility model gives up the design of existing light guide plate, this anti-dazzling screen 2 changing mining height reflection material and this reflector plate 1 comprising described reflecting medium 11 are to reach the effect of existing light guide plate, and utilize the more existing light guide plate of this thickness also to want this thin light transmission piece 3 to separate this reflector plate 1 and this anti-dazzling screen 2, the light beam that this light source 4 is sent has enough spaces to reflect between this reflector plate 1 and this anti-dazzling screen 2, and can meet modern product and pursue thin purpose of design.
In sum, the end faces being formed at this reflector plate 1 by means of described reflecting medium 11, the light beam of this light source 4 constantly can be reflected between this reflector plate 1 and this anti-dazzling screen 2, to replace the effect of the light guide plate of existing costliness, and the mode that direct punching adopted by this anti-dazzling screen 2 makes light beam can penetrate from described punching 21, relatively simple and easy many on processing procedure, so really can the purpose of this utility model be reached.
As described above, be only embodiment of the present utility model, when can not limit the scope of the utility model enforcement with this, namely all simple equivalences done according to the utility model claims and description change and modify, and all still belong to scope of the present utility model.
