Embodiment

In the detailed description of the invention, many details have been set forth below so that understand the present invention up hill and dale.But, will be appreciated that the present invention still can implement if there are not these details.In other cases, do not introduce well-known method, step, element, parts and device in detail in order to avoid that feature of the present invention is thickened is unclear.

Reflector can use a series of sphere or spherical lenses made from optical material to come reflection ray.In other cases, reflector can use a series of half-angle prisms made from optical material to come reflection ray.Sometimes, the half-angle prism can combine reflection ray with sphere or spherical lens.Under some other situation, reflector can use a series of full-shape prisms made from optical material to come reflection ray.

The present invention relates to be used for making the method and apparatus of reflective thin slice or film, reflective thin slice or film can be as the elements of reflector or reflector.Reflective thin slice or film can have the optical material surface that formed by a series of microstructure half-angle prisms or full-shape prism with reflection ray.In one embodiment, reflective thin slice of the present invention or film can utilize knurling rolls to make by extrusion process.

The half-angle prism has two interfaces, and wherein incident ray is reflected twice and returns incident light source again.The full-shape prism adopts three interfaces, and wherein incident ray is reflected three times and returns incident light source again.In general the full-shape prism can provide in a big way angle that incident ray can be received and back light source again.If the loss in the optical material is very low, the full-shape prism can reflect more effectively than half-angle prism.Yet the full-shape prism is difficult to be made.In general, reflective film has the film of half-angle prism pattern to make by impression, and described half-angle prism pattern reflects incident ray at a predetermined angle naturally.

The typical method of making a series of half-angle prisms in reflective thin slice or film is by molding, machine cuts and Sheet Metal Forming Technology.

It is the mould of determining for given pattern that mould process needs one usually.Molten plastic or other similar optical material of liquid form are poured in the mould.Optical material needs have reflective characteristic one period hardening time with formation shape in mould.Hardening time can be quite long.And mould also is not suitable for optical material formation full-shape prism.

Machine cuts processing need be portrayed plastics or other optical material with pattern one by one with lathe usually.It is very time-consuming to portray pattern one by one, thereby is not a kind of economical method of making the reflecting material continuous slice.

In general punching course needs the rectangular die with fixed pattern.Soft semi-solid or semi-liquid optical material such as plastics are struck out the shape with reflective characteristic by punch die.Also very slow and not too economical with the zone that the rectangular die punching press is limited.

These typical process usually can add seam so that enough sizes to be provided between the Christmas tree pattern of reflective thin slice or film.Seam is destroyed Christmas tree pattern and is opaque, thereby can reduce reflectivity or intensity efficiency.

These typical process can form continuous half-angle prism pattern on finite region, such as being not more than nine inches continuous pattern (i.e. " nine inches pattern blocks ") of taking advantage of nine inches, taking advantage of in 48 inches the thin slice at one 48 inches has 36 nine inches pattern squares.In some cases, nine inches pattern blocks may make practical application be limited to this size, otherwise need careful splicing to form bigger pattern.

The present invention can form does not have the microstructure film of seam to roll up continuously, thereby almost can be the seamless reflective film of any length for client provides.By when making reflective thin slice, eliminating seam, can improve reflection efficiency, and owing to the increase of Christmas tree pattern density can reduce cost.

For continuous reflective film volume is provided, need the microstructure cylindrical shape mould that is carved with optical design on a kind of surface.This microstructure cylindrical shape mould is referred to herein as knurling rolls.In the optical material such as thermoplastic materials by the heat of continuously pattern being stamped, this microstructure cylindrical shape mould is impressed into its pattern in the plastic film.Utilize common technology to be difficult to half-angle or full-shape prism pattern are carved into the cylindrical shape mould.

Knurling rolls provide the instrument that is used for manufacture process, make it possible to make continuously the microstructure reflective film that has half-angle prism and/or full-shape prism.Accurate corner cube groove can form on three-dimensional surface.Different with solid cylinder or roll, the cylindrical pattern of knurling rolls is made of the multi-disc sub pattern.Knurling rolls use one or more narrow rings that closely stack or pad to form the overall cylindrical pattern.Each annulus or pad are cut one by one to constitute the part of pattern.In an embodiment, the width of annulus is less than one millimeter.The annulus or the pad of the close arrangement side by side by using various different numbers can form the cylinder of the different in width that has the pattern that requires.

Knurling rolls can provide the big continuous reflection face that has the full-shape prism.That is, the surface of reflective film or thin slice can form the continuous reflection face of wide endless.By using one or more annulus or pad to form the overall cylindrical pattern of knurling rolls, can regulate the angle of full-shape prism surface, comprise making each annulus have different angles.Can form the full-shape prism by the sub pattern alignment thereof of checker from the annulus to the annulus.As a result, can in the surface of optical material, form a lot of reflection angles and reflecting effect with reflection or back reflection incident ray.The cube corner that annulus by changing the overall cylindrical pattern or pad can easily be adjusted prism (promptly broaden or narrow down) and the degree of depth (promptly shoal or deepen) are changing its orthogonality, thus the reflection characteristic of change reflective film and final products.Big darker prism can form in the surface and reflective qualities is incurred loss.The adaptability of knurling rolls is very strong, because utilize the different makes of same instrument can make different reflection sheets or film.Need only just can revise the overall cylindrical pattern by the make that changes annulus or pad.On knurling rolls, can there be the corner cube of many sizes and kind to coexist as simultaneously in the scope on the knurling rolls face of cylinder to form the overall cylindrical pattern.
