Description

Ultra-thin interactive logo that household electrical appliances use and preparation method thereof
Technical field
The present invention relates to an electro-technical field, be specifically related to ultra-thin interactive logo of a kind of household electrical appliances use and preparation method thereof.
Background technology
In recent years, electronic product is just towards large scale, ultra-thin future development, logo is as the embodiment of a corporate image, increasing user more focuses on the interaction of individual and product, interactive logo will become embodiment product brand image, can meet user simultaneously and make corresponding feedback when operating.
Traditional luminous logo is that after adopting injection moulding or the PMMA sheet material of cutting, printing forms light guide plate, the mode of assembling translucent logo again in the front of light guide plate makes luminous logo, this technique is difficult to the light emitting control realizing logo single letter, and the material thickness of injection moulding is difficult to accomplish ultra-thin, and injection moulding needs injection mold, thus add injection moulding cost; Another kind of luminous logo uses LED directly in translucent logo back side illuminated, can realize beating letter light emitting control separately, but being uniformly distributed of light cannot be realized, and each letter needs multiple LED to control, at double add luminous power, but too increase the cost of LED simultaneously.
Summary of the invention
Instant invention overcomes in prior art and use LED directly at the non-uniform light that translucent logo back side illuminated exists, use the too much more high deficiency of LED cost, there is provided one can realize each letter luminous separately, and can uniformly light-emitting reach luminosity household electrical appliances use ultra-thin interactive logo.
For achieving the above object, the present invention is by the following technical solutions:
The ultra-thin interactive logo that a kind of household electrical appliances use, it comprises translucent or transparent logo layer, its surface shows several letters, described translucent or transparent logo layer side is provided with protective film, opposite side is provided with transparent bonding layer, and this translucent or transparent logo layer is bonded with backlight active layer by transparent bonding layer, described backlight active layer is primarily of back light unit, reflective material layer and flexible PCB composition, the number of described back light unit is identical with the number of letter, and this back light unit and alphabetical one_to_one corresponding are arranged, described back light unit is made up of light guide plate and LED, described LED is arranged on flexible PCB, one end end face of described light guide plate contacts with LED, this end face is incidence surface, the front of described light guide plate is exiting surface, the back side is connected with reflective material layer.
Further technical scheme is, described exiting surface is provided with several light guiding points, and described light guiding points is evenly arranged, and the spacing between adjacent two light guiding points is 0.001mm.
Further technical scheme is, described light guide plate adopts PC sheet material, acryl plates or PET sheet material composition.
Further technical scheme is, the thickness of described LED is 0.4mm.
Further technical scheme is, described LED is arranged on flexible PCB by the mode of welding.
Further technical scheme is, described reflective material layer is black and white glue or masking foil.
Further technical scheme is, described transparent bonding layer is glue or adhesive tape.
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.
