Description
Technical field
The present invention is the structure that a kind of optics spreads anti-dazzle plate, belongs to technical field of LED illumination.
Background technique
High-quality LED area light source needs high uniformity of luminance, high light emission efficiency.Since LED itself is light
Source, the realization of area source are the diffusions for first constructing pointolite array, then carrying out light, just LED point light source can be made to become to compare in this way
Uniform area source.In order to realize high energy utilization, the total reflection during light outgoing need to be reduced as far as possible, while lamps and lanterns are also
Meet the requirement of anti-dazzle.
Dazzle is a kind of visual experience, i.e., usually said " twinkling ".International lighting association is to the anti-dazzle finger of the unification of lamps and lanterns
Number (UGR) is distinctly claimed --- and lamps and lanterns must satisfy UGR < 19." a kind of anti-dazzle that 204829356 U of patent CN is mentioned
Panel light ", structure successively include backboard, EVA, reflector plate, light guide plate, optical diaphragm and diffuser plate；Patent CN 206378615
A kind of efficient diffusion barrier that U is mentioned, including substrate are provided with diffusion layer on substrate two sides, are additionally provided on the diffusion layer of inside
The staggered anti-dazzle photosphere of micro-structure；A kind of prism diffuser plate that 107167856 A of patent CN is mentioned, structure include substrate,
Micro-prism structure and diffusion layer.The multilayered structure combination of above-mentioned patent can not make UGR up to standard up to (i.e. UGR < 19) completely, and
Complex process, production cost are higher.
Summary of the invention
In order to overcome the deficiencies of the prior art, the present invention is directed to propose a kind of optics spreads anti-dazzle structure, and one is provided simultaneously
The kind optics spreads the preparation method of anti-dazzle structure.The present invention spreads antiglare layer in the one side production single layer micro-structure of transparent substrate, should
Anti-dazzle light effect and diffusion effect can be combined into one by diffusion antiglare layer, integrated molding, and preparation process is simple.
Single layer micro-structure diffusion antiglare layer of the present invention is the transparent convex spherical cap-shaped structure of random arrangement, convex spherical crown
Tangent or nearest back gauge is no more than 3 μm between the spherical crown of shape structure.The spherical crown of convex spherical cap-shaped structure varies, and large ball prefix is straight
Diameter is between 20 μm -50 μm, and between 25 μm -40 μm, the average diameter of small spherical crown is the 35%- of large ball prefix
80%, preferably 50%-70%.Large ball prefix in convex spherical cap-shaped structure is single-size, and small spherical crown is one or more sizes
Combination.The white space between big ball has been filled up in the introducing of bead, increases the duty ratio of micro-structure, can further promote diffusion
With antiglare effect.
Transparent substrate thickness is the membrane material or plate of 0.5mm-3mm.Wherein membrane material can be PET, PEN, PC or transparent PI etc.
Any one of, plate can be any one of glass, PMMA, PC or PS etc..
The material that single layer micro-structure spreads antiglare layer is transparent coining glue, can be thermoplastic polymer, thermosetting property polymerization
One of object and UV curable polymers are integrally formed, are prepared over the transparent substrate by imprint process.Preparation method
The following steps are included:
I. compact arranged big spherical structure is obtained in the one side of substrate by the way of self assembly；
II. bead is filled in the gap of the big spherical structure of step I, obtains required micro-sphere structure；
III. the recessed spherical cap-shaped structure complementary with micro-sphere structure is made using reverse mould technique, forms template；
IV. so that transparent coining glue is formed convex spherical cap-shaped structure using stamping technique --- i.e. single layer micro-structure diffusion is anti-dazzle
Layer.
The invention has the characteristics that and good result:
Only need common diffuser plate is replaced using this anti-dazzle diffuser plate in LED lamp, can reach not only spread but also
The purpose of anti-dazzle (UGR < 19), and it is low in cost, it can be widely applied.
The preparation method of the diffusion antiglare layer includes the steps that above-mentioned I-IV, and preparation process is simple, can large area production.
Using the recessed spherical cap-shaped structure template in step III, commercial quantities factory can directly be carried out by stamping technique.
The specific embodiment of the invention is described in detail below in conjunction with attached drawing, will become more apparent to one of ordinary skill in the art
Technical characteristic of the invention.
Detailed description of the invention:
Fig. 1 is that optics according to an embodiment of the present invention spreads anti-dazzle feature cross-section schematic diagram；
