Further: above-mentioned reflectance coating is black and white reflectance coating, white reflection film or silver color reflectance coating; Wherein,
Black and white reflectance coating comprises base material, is black side below base material, is white face above base material; Base material is polyethylene terephthalate material, base material by double faced adhesive tape on surface label or printing water-based glue and light guiding film bonding;
White reflection film, material is PET, is divided into band glue and is not with two kinds, glue; If be not with glue, its by double faced adhesive tape on surface label or printing water-based glue and light guiding film bonding;
Silver color reflectance coating, thus it is for processing the effect that makes its effect that produces minute surface produce reflection ray at pet sheet face.
Further: above-mentioned light guiding film upper surface is provided with clear PET film, the surface of clear PET film is printed one deck white layer and one deck black layer successively; Between clear PET film and light guiding film, adopt double faced adhesive tape or water-based glue to paste.
Further: above-mentioned reflectance coating below medium position is provided with FPC, and FPC connects with power supply by standard port, and LED and resistance component are housed on FPC; The medium position of described light guiding film is provided with light inlet; Light inlet place is arc-shaped structure or polygonized structure, also can be according to different LED lamp type design difformity.
The beneficial effects of the utility model:
The utility model discloses a kind of keyboard light guiding film module, its core component is the light guiding film of reflectance coating and top thereof, and this combination can make light guiding film produce light, and this brightness can make the content on keyboard clearly be identified by people; More specifically; the utility model can be protected light guiding film by the PET film that most surface is set; provide LED light source by FPC is set, LED light source can further increase the brightness of light guiding film, even if the press key contents on keyboard is all very easily identified in pitch-dark space.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is a kind of embodiment structural representation of light guiding film.
Description of reference numerals:
1-FPC, 2-reflectance coating, 3-light guiding film, 4-clear PET film, 5-light inlet, 6-LED; In Fig. 2, A representative is the lighting angle of LED.
Embodiment
Below in conjunction with drawings and Examples, the utility model embodiment is described:
Fig. 1 and Fig. 2 show a kind of embodiment of the present utility model, and as shown in Figure 1, the utility model keyboard leaded light module comprises:
The bottom is FPC 1, and FPC 1 connects with power supply by standard port, and the parts such as light emitting diode (LED) and resistance are housed on FPC, and LED quantity and specification are different according to different demands;
Also comprise reflectance coating 2, this reflectance coating 2 has following several conventionally:
(black side down for a, black and white reflectance coating, white is facing to light guiding film, namely upward), white face can return light guiding film by the light reflection of light guiding film, and black side can prevent that light from spilling, and base material is polyethylene terephthalate material, be commonly called as PET, this material carries glue and is not with two kinds, glue, according to choice for use under different situations, as select not when the material with glue need to be on surface label double faced adhesive tape or printing water-based glue and light guiding film bonding;
B, white reflection film, material is PET, is divided into band glue and be not with two kinds, glue, need to be on surface label as selected not the material with glue time double faced adhesive tape or print water-based glue and light guiding film bonding;
C, silver color reflectance coating, thus its method for making is to do at pet sheet face the effect that special processing makes its effect that produces minute surface produce reflection ray;
Also comprise light guiding film 3, material is polycarbonate (being commonly called as PC) or Polyurethane Thermoplastic Elastomer rubber (being commonly called as TPU), thickness can be selected according to different designing requirements, commonly using thick is 0.1～0.5mm in scope, the surface design of light guiding film has leaded light site, site can be produced on front or the reverse side of material, compressing/printing/Laser Processing that the processing mode of site is divided into mould etc.;
White/black ink can be printed off in the region of the surface of above-mentioned light guiding film 3 beyond the button character, in order to promote brightness and to reach the effect of shading;
Also comprise, clear PET film 4, because PET has higher hardness and processing characteristics, prevents light guiding film surface tear herein, after surface printing white republishes black, can also play the effect of protection and shading, between PET and light guiding film, can adopt double faced adhesive tape or water-based glue to paste;
