[0033] Such as figure 1 As shown, the arrangement of the centrally symmetric figures as regular hexagons is as follows: another regular hexagon equal to the side lengths of the above regular hexagons is respectively arranged at an equal vertical distance from the outside of the six sides of each regular hexagon. The adjacent side lengths of the adjacent regular hexagons are parallel to each other, and extend around the substrate based on the above-mentioned centrosymmetric figure, so that the vertical distance between the side lengths of two adjacent regular hexagons is the same, which is 0.2-2um , the side length of the regular hexagon is 0.2-2.5um.

no. 2 example

[0035] Such as figure 2 As shown, the arrangement of the centrally symmetrical figure as a circle is as follows: the radius of two adjacent circles is the same and the distance between the centers of the two circles is equal, and the above-mentioned centrally symmetrical figure is used as the reference unit to extend around the substrate. The lengths of adjacent circles are parallel to each other, and extend around the substrate with the above-mentioned centrosymmetric figure as a reference unit, so that the shortest distance between the circumferences of two adjacent circles is the same, which is 0.2-1.5um. The radius of its circle is 0.2-4um.

no. 3 example

[0037] Such as image 3 As shown, the centrosymmetric figure is a regular hexagon composed of a circle in the center and six symmetrically distributed identical regular hexagons separated from the circle. Another regular hexagon that is equal to the side length of the regular hexagon circumscribed by the above-mentioned circle, the adjacent side lengths of adjacent regular hexagons are parallel to each other, and the radius of the circle is 1 / 2 of the side length of the regular hexagon Times, using the above-mentioned centrosymmetric figure as the reference unit to extend around the substrate, so that the vertical distance between the side lengths of two adjacent regular hexagons and the shortest distance between the circle and the adjacent regular hexagons are the same, both It is 0.2-2um, and the side length of its regular hexagon is 0.2-2.5um.

Abstract

The invention relates to a high lighting effect pattern substrate and a manufacturing method thereof. Centrosymmetric patterns are etched on the substrate and extend to the periphery of the substrate. The centrosymmetric patterns are quadrates, regular hexagons, circles, equilateral rhombuses with 60 degrees of angles, regular hexagons formed by six same regular triangles, regular hexagons formed by six symmetrically distributed same regular triangles with circular centers and embedded circles, and regular hexagons formed by six symmetrically distributed same regular hexagons with circular centers and being separated from the circles. The centrosymmetric patterns extend to the periphery of the substrate as reference units so that the vertical distance between the side lengths of two adjacent quadrates, the vertical distance between the side lengths of two adjacent regular triangles, the vertical distance between the side lengths of two adjacent regular hexagons, the vertical distance between the side lengths of two adjacent equilateral rhombuses, the shortest distance between circumferences of two adjacent circles and the shortest distance between the circles and the adjacent regular hexagon are mutually equal.

Description

technical field [0001] The invention relates to a high-light-efficiency graphics substrate and a manufacturing method thereof, in particular to a high-light-efficiency graphics substrate for an LED light source and a manufacturing method thereof. Background technique [0002] Semiconductor lighting is the basic industry of green industry. With the comprehensive promotion of "low-carbon economy", green lighting has attracted more attention from governments. In order to achieve a low-carbon economy in the field of lighting, governments of various countries have proposed and implemented green lighting projects. Various countries and regions have formulated policies to support the development of the LED lighting industry. At present, people are developing and promoting semiconductor lighting stereotyped products with remarkable energy-saving effect and high cost performance to replace incandescent lamps and tungsten halogen lamps; developing and promoting functional semiconduct...
