The method for making of the ultra-thin interactive logo that the present invention also provides a kind of household electrical appliances to use, it comprises the following steps:
Step 1, translucent or transparent logo layer makes
PMMA sheet material, PET sheet material or PC sheet material are formed logo layer by CNC machine Milling Machining or transparent material or trnaslucent materials injection mo(u)lding are formed logo layer;
Step 2, backlight active layer makes
On the exiting surface of light guide plate, light guiding points is formed by the mode of UV transfer printing, hot pressing or laser engraving, connect LED in light guide plate one end simultaneously, LED is welded on flexible PCB, material is thus formed a back light unit, foamed glue is adopted to be processed by cross cutting again, foamed glue is sized to the size of back light unit, and back light unit is fixed on foamed glue.
Step 3, reflective material layer makes
Black and white glue or masking foil are cut into required size;
Step 4, assembling
Backlight active layer front is adhered to translucent or transparent logo layer by transparent glue or adhesive tape, the backlight active layer back side is pasted on reflective material layer.
Further technical scheme is, the surface being also included in translucent or transparent logo layer pastes layer protecting film.
Compared with prior art, the invention has the beneficial effects as follows:
1, optical grade board making light guide plate is adopted in the technical program, by UV transfer printing in light guide plate, the mode of hot pressing or laser engraving forms luminous point in light guide plate surface, when the light source that LED light produces enters light guide plate, diffuse reflection is there is at luminous point place, thus reach the requirement of uniformly light-emitting, improve the luminosity of LED simultaneously, overcome in prior art and need to adopt multiple LED to increase the shortcoming that luminous power exists high cost, this just makes light guide plate be provided with the function of diffusion sheet, the use of diffusion sheet is just eliminated in Total Product installation process, thus reduce the thickness of cost and Total Product.
2, the light guide plate in the technical program in backlight active layer adopts optics pole PC sheet material, acryl plates or the process of PET sheet fabrication, and this material technology is ripe, and cost reduces relatively, and processing technology easily realizes robotization;
3, the fine and closely woven and distribution of the luminous point that light guide plate surface in the technical program is formed all with, do not need just can reach effect that is soft, uniformly light-emitting by diffusion sheet;
4, the ultra-thin light-emitting logo structure in the technical program adopts backlight and translucent or transparent logo directly to fit, and centre does not need to use diffusion sheet, and this structure is simple, omits diffusion sheet and corresponding assembly process;
The light-emitting area of the backlight active layer 5, in the technical program is fitted with translucent or transparent logo layer; logo outside surface is coated with diaphragm; this setting can prevent logo in transportation by dust or fingerprint pollution; prevent light guide plate surface from forming dirt, thus keep the illumination effect that logo is good.
