The technical scheme that its technical problem that solves the utility model adopts is: a kind of computor-keyboard hot pressing light guiding film module; Module comprises light guiding film, photomask and light source; Light guiding film is a light-emitting area simultaneously, and hot pressing has the leaded light site on the another side, and photomask is arranged on the light-emitting area of light guiding film; Be engraved structure corresponding to the pairing character position of keycap on keyboard place on the photomask, light source is arranged on light guiding film side or centre position.
The technical scheme that its technical problem that solves the utility model adopts further comprises:
Leaded light site on the described light guiding film is provided with corresponding to the pairing character position of keycap on keyboard place.
Described photomask comprises high light-transmission substrate, white ink and black ink, and white ink is arranged on the high light-transmission substrate, and black ink is arranged on the white ink.
Described high light-transmission substrate adopts the PET material.
Described photomask is bonded on the light guiding film through glue.
Described light source comprises LED and FPC, and LED is installed on the FPC.
The one side that described light guiding film is provided with the leaded light site is provided with reflective or the expansion luminescent material.
Described light guiding film material adopts the PC material.
The beneficial effect of the utility model is: the integral thickness of the utility model has only 0.5mm; It is simple in structure, light, easy for installation; The utility model adopts 5-15 side-emitting LED to form light source; Luminous evenly the utility model can also send the light of different colours according to the ID designing requirement, also can accomplish lamp effect effect of breathing.Through the utility model can make ultra-thinization of computor-keyboard, gentlier, more gorgeous, to improve the class of computer product, increase product market competitiveness.Compare with similar illuminated keyboard product, adopt the utlity model has easy for installation, cost is low, luminous evenly, the life-span is long, change characteristics such as convenient.
To combine accompanying drawing and embodiment that the utility model is further specified below.

Embodiment
Present embodiment is the utility model preferred implementation, and other all its principles are identical with present embodiment or approximate with basic structure, all within the utility model protection range.
The utility model mainly comprises light guiding film 1, photomask 9 and light source, and in the present embodiment, the material of light guiding film 1 is selected FPC8 for use; Light guiding film 1 thickness is generally 0.25-0.30mm, opens hot pressing light guiding film 1 mould according to different machine types with the optical-fiber laser machine, goes out leaded light site 2 (reflective structure) with mould hot pressing on the FPC8 film; Be made into light guiding film 1; In the utility model,, be defined as the light-emitting area of light guiding film 1 with the one side that is not provided with leaded light site 2.In the present embodiment; Go up according to disparity items character (being the pairing character of keycap on the keyboard) in the light-emitting area (being non-leaded light site 2 faces) of light guiding film 1 and to make photomask 9, around photomask 9,, photomask 9 and light guiding film 1 light-emitting area are bonded together with non-luminous region brush coating water 6; Effect is only to make keypad character luminous; Non-character zone is not allowed it to have light to appear to come, and whole like this keyboard looks that to have only character luminous, clear, makes a distinction between the important and the lesser one.In the present embodiment, photomask 9 main bodys adopt high clear PET 3 materials, are brushed with high hiding rare white ink 4 on the PET3 material, are brushed with high hiding rare black ink 5 on the white ink 4, scribble glue 6 on the black ink 5.In the present embodiment; In the high hiding rare white ink 4 of high clear PET 3 surface printings, after light sent from light guiding film 1 surface, white ink 4 can play reflection action; Make the light on light guiding film 1 surface stronger; Should be noted that during white printing ink 4 and get out of the way the keypad character light-emitting zone, make light can see through keyboard cover, reach the purpose that illuminates character.In white ink 4 surface printings one floor height hiding rare black ink 5, do not need the light of light-emitting zone to cover on keyboard, do not allow light to see through keyboard from other positions; Make keypad character seem clear; Note during brush printing ink and get out of the way the keyboard character emitting, make light see through keyboard cover, during practical implementation from keypad character; High clear PET 3 is through on the bonding light guiding film 1 of glue; Be printed with on the photomask 9 on the one side of black ink 5 and scribble glue 6, the utility model is adhered on the keyboard steel disc, play fixation through glue 6.In the present embodiment, have in hot pressing on the light guiding film 1 to be provided with reflective on the one side of leaded light site 2 or to expand luminescent material, reflective or expand around the luminescent material and non-luminous region brush coating water; Reflective or expansion luminescent material are adhered on the light guiding film 1 site face; In the present embodiment, PET film reflective or that the expansion luminescent material can adopt inside to be provided with high reflecting material is processed, or adopts commercially available reflective membrane, reflecting piece; When illumination is mapped to reflective or expand on the luminescent material; Through reflective or expansion luminescent material light is reflexed on the computor-keyboard again, auxiliary light guiding film 1 is luminous, makes whole light-emitting area more even.Light source in the present embodiment is employed in FFPC8 and goes up installation side emitting led 7; Make the light source of 1 group of light guiding film; FFPC8 is attached to computor-keyboard hot pressing light guiding film 1 site face side or middle optional position all around; Make light source inject light guiding film 1, through the site above the light guiding film 1 reflect, reflection source, utilize reflective again or to expand the auxiliary computor-keyboard hot pressing light guiding film 1 that makes of luminescent material luminous uniformly.
