Description
Technical field
Exempt from silk-screen light guide plate with improvement micro nano structure the utility model relates to a kind of, belongs to illumination optical technology neck
Domain.
Background technique
Light guide plate is acrylic/PC plate material using optical grade, and then using has high reflectivity and the not high-tech of extinction
Skill material is stamped in the acryl plates bottom surface laser engraving, V-type cross grid engraving, UV screen printing technology of optical grade
Light guiding points.Allow light in material by the change of surface texture texture using its high refractive index and the not material property of extinction
Internal refraction is expected, so that linear light source to be changed into the high-tech product of area source.
The surface processing of existing light guide plate is general in the following way:
1) laser engraving: although the light guide plate of laser engraving can be made with full page, arbitrarily cutting is used, and can also individually be advised
The special plate-making of lattice, but efficiency is very low, fraction defective is high, and the production cycle is long, is not easy to produce in batches.
2) V-type cross grid is carved: V-type cross grid engraving is that one layer of corrosion resistant light is coated on a smooth silicon wafer
Photoresist then allows strong light by reticle, thinks that the graphical information of the certain layer of production is selectively exposed in reticle:
Then the photoresist after development is removed, silicon wafer upper surface will form the film with micrographics structure, using photolithographicallpatterned system
The light guide plate surface rent rugosity of work is not good enough, and the loss of luminous energy is bigger.
3) UV screen painting: although UV screen painting is without disadvantage mentioned above, each specification of light guide plate all must be individually
Plate-making, finished product cannot arbitrarily be cut, so using upper existing defects.
4) traditional handicraft is molded: traditional handicraft injection molding is directly injected into one inside light guide plate in guide-lighting plate injection moulding
Kind has the transparent grain material of scattering function, and the concentration by reasonably adjusting transparent grain reaches effective control to light out
System, be finally reached high evenness goes out light, since doping process is not easy accurately to control, so being suitble in production using injection molding manner
The light guide plate of small size will appear the non-uniform problem of light out for large-sized light guide plate.
Currently, have Chinese patent " a kind of plane exempt from print light guide plate " (application No. is 201621087041.X), it is open
A kind of plane exempts to print light guide plate, including transparent substrate layer, and is uniformly distributed and makes an addition to inside the transparent substrate layer, makes
Incident light encounters the composite sphere that spherical particle scatters again.
There is Chinese patent " one kind exempts from silk-screen light guide plate " (application No. is 201721049599.3) again, provides one kind and exempt from silk
Light guide plate is printed, light guide plate has incidence surface, light-emitting surface and lattice point structure, and lattice point structure is arranged on light-emitting surface, and light-emitting surface includes
Upper side edge, lower side, left side, right edge, the first center line of upper side edge and lower side, left side and right edge second in
Heart line, lattice point structure are made of the spherical site of several semicircles, and site gradually increases from upper side edge to the density of the first center line
Greatly, site is gradually increased from lower side to the density of the first center line, site from left side to the density of the second center line gradually
Increase, site is gradually increased from right edge to the density of the second center line, and the thickness h of light guide plate is 1.5 to 5mm, and site is arrived
Height of projection n in smooth surface is 0.05 to 0.5mm, and the radius r of site is 0.1 to 0.5mm.
Current above-mentioned light guide plate all can't the large-sized light guide plate of very good solution will appear that light out is non-uniform to ask
Topic.
Summary of the invention
In view of the above-mentioned problems of the prior art, the utility model provides and a kind of exempts from silk with improvement micro nano structure
Print light guide plate, can direct extrusion forming, directly cut uses, without surface get ready or silk-screen process, production is effectively reduced
