CN201045629Y - Ellipse partial shaped lenticulation - Google Patents

Abstract

An ellipse partial shape lenticulation of the utility model is an optical material for making solid and variant images. The transparent material with the novel structure of the utility model comprises a flat and smooth focus imaging plane (1) and focus small lenses groups (2) arranged compactly and evenly with ellipse-end-shape cross sections. The ellipse partial shape lenticulation of the utility model reduces the spherical aberration to ensure the coaxial light brighter and sharper and the off-axis light clearer, thereby improving the ornamental effect of the solid and variant images. Further, the utility model can utilize thinner materials to obtain better imaging effect, thereby reducing the manufacturing cost. The utility model has the promising market for the solid and variant images.

Description

Oval local shape lenticulation

Technical field:

The utility model relates to a kind of solid or variation is decorated and optical material---the oval local shape lenticulation of advertisement picture moulding.

Background technology:

Along with the development of society and the raising of people's enjoing ability, solid, variation decoration painting and advertisement poster enter in the middle of the daily life, and progressively obtain common people's welcome.The material of manufacturing in the past all uses slit grating and column mirror grating.The black lines on slit grating surface shuts out the light, and causes luminance shortage; The intrinsic spherical aberration of tradition column mirror grating arc surface, cause the edge pixel correctly not extract, image blurring fainting, acutance and sharpness are not enough, make the conversion of change picture unclear, the stereogram spatial impression reduces, and just must increase the column mirror grating material thickness if will promote the picture stereoeffect, has strengthened production cost.

Summary of the invention:

The utility model is simultaneously made smooth, smooth focal imaging plane (1) with the transparent material base, and it is tight, evenly distributed that another side is made, and xsect is the lenslet group (2) of oval head portion shape.

The oval local shape lenticulation that the utility model provides has been avoided slit grating to the blocking of light, and has reduced the spherical aberration that traditional column mirror grating produced, and has improved the parsing power of material to pixel, makes conversion clear, and stereoscopic sensation obviously strengthens.Simultaneously, allow to use thinner material to obtain the better pictures effect, reduced production cost.

Description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a horizontal side cross-sectional view of the present utility model;

Fig. 3 is that light beam passes through track of the present utility model.

Embodiment: main shaft light L1 with from axle light L2, focus on 003 place and 004 place of (1) respectively by elliptical lenses 001, its ball-shaped aberration and coma obviously are improved and reduce.The dark d of arc is minimized, and has improved L2 simultaneously by the possibility of adjacent camera lens 002 reflection, has reduced ghosting.

Dig, cut out and manufacture roll-type of the present invention or dull and stereotyped master mold with a half elliptic cutting tool, on plastics machinery, add the cost product with this master mold.

Claims (1)

1. oval local shape lenticulation is characterized in that: be carrier with the transparent material, one side is smooth, smooth focal imaging plane (1), and another side is tight, evenly distributed, and xsect is the focusing lenslet group (2) of oval head portion shape.
