Abstract
The utility model relates to a kind of light conducting plate structures, micro-structure face made of hot pressing is all made of on the top and bottom of the light conducting plate structure, multiple compact arranged arc raised lines that micro-structure face is formed by hot pressing on light guide plate form, and the point ring for multiple irregular alignments that micro-structure face is formed by hot pressing under light guide plate forms.The utility model has high conversion rate, brightness uniformity, the fine and smooth soft feature of light.
Description
Technical field
The utility model relates to light guide plate production technical field, in particular to a kind of light conducting plate structure.
Background technique
Light guide plate (light guide plate) is acrylic/PC plate material using optical grade, then high anti-with having
Rate and the not hitech materials of extinction are penetrated, carve in the acryl plates bottom surface laser engraving of optical grade, V-type cross grid,
UV screen printing technology stamps light guiding points.The light issued from lamp is drawn in optical grade acrylic using optical grade acryl plates
The stop of plate surface, when light is mapped to each light guiding points, reflected light can be spread toward all angles, then destroy conditioned reflex
It is projected by light guide plate front.By various densitys, light guiding points not of uniform size, light guide plate uniformly light-emitting can be made.
However, the luminous efficiency of existing light guide plate is universal relatively low (light efficiency is less than 80%), and there are brightness irregularities, out
The disadvantages of existing bright border or dark space.
Utility model content
In view of the above problems, the utility model devises the production method and its structure of a kind of light guide plate, it is existing to solve
The problem of luminous efficiency existing for light guide plate is low, brightness irregularities.
The technical solution of the utility model is: micro-structure made of hot pressing is all made of on the top and bottom of the light conducting plate structure
Face, multiple compact arranged arc raised lines that micro-structure face is formed by hot pressing on light guide plate form, micro-structure face under light guide plate
The point ring of the multiple irregular alignments formed by hot pressing forms.
Preferably, the height of arc raised line among the above is 15-25 μm, width is 140-160 μm.
Preferably, point ring annular groove made of hot pressing among the above forms, the depth of the annular groove is 1.8 μm,
Annular groove width is 12.5 μm, and the diameter of outer ring is 55-65 μm.
Preferably, above-mentioned light-guide edge be provided with 2-5mm be left white region.
The beneficial effects of the utility model are: there is conversion ratio using the light guide plate that the method for the utility model is produced
High, brightness uniformity, the fine and smooth soft feature of light.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the light guide plate of the utility model.
Fig. 2 is the plan view at the light guide plate point anchor ring of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figs. 1-2, it is all made of micro-structure face made of hot pressing on the top and bottom of the light conducting plate structure of the utility model,
Multiple compact arranged arc raised lines 1 that micro-structure face is formed by hot pressing on light guide plate 2 form, the lower micro-structure face of light guide plate 2
The point ring 4 of the multiple irregular alignments formed by hot pressing forms.
The height H of arc raised line 1 among the above is 15-25 μm, and width L is 140-160 μm.
4 annular groove 3 made of hot pressing of point ring among the above forms, and the depth H 1 of annular groove 3 is 1.8 μm, and annular groove 3 is wide
Spending W is 12.5 μm, and the diameter D of 3 outer ring of annular groove is 55-65 μm.
Above-mentioned light-guide edge is provided with 2-5mm and is left white region 5, and the effect for being left white region 5 is to allow light to enter from side to lead
Tabula rasa.
Above are merely preferred embodiments of the utility model, for those skilled in the art, exist
Under the premise of not departing from the utility model principle, several improvement can also be made, these improvement also should be regarded as the utility model
Protection scope.
