The light panel processor may determine the location 600 of the groove in consideration of the light intensity and the light direction on the light panel indicated by the user input information. The light panel processor may sell the groove in various forms such as a straight line or a curve according to the position 620 of the groove determined on the light panel. In other words, the position of the groove may be a line (or groove line) on the light panel on which the groove structure is formed. That is, the light panel processor can form a groove structure on the groove line.

The location 600 of the groove may be determined by additionally considering the location of the light source as well as user input information.

7 is a conceptual diagram illustrating a method of implementing a surface roughening device according to an embodiment of the present invention.

In FIG. 7, a method for implementing a groove structure on a surface roughness light emitting device in consideration of a position of a light emitting part is disclosed.

Referring to FIG. 7, as the distance between the groove structure and the light emitter 720 increases, the amount of light reflected by the light emitted from the light emitter 720 may be reduced, thereby reducing the amount of light generated in the groove structure. The intensity can also be reduced. Therefore, in the surface roughening device according to the embodiment of the present invention, the inclination of the surface may be changed on the groove structure in consideration of the distance between the groove structure and the light emitting part 720.

The light panel processor may determine the distance based on the light emitter 720 to form the groove structure. For example, when the groove structure is to be implemented at the first distance 750, the second distance 760, and the third distance 770, the surface of the groove structure to be positioned at the first distance 750 may be formed by the reflector. The surface of the groove structure to be located at the second distance 760 with the first angle 755 based on the parallel surface has the second angle 765 with respect to the surface parallel to the reflecting plate, and the third distance. The surface of the groove structure to be positioned at 777 may have a third angle 775 based on the surface parallel to the reflecting plate.

If a certain amount of light is to be generated in the entire reflecting plate, the above-described cross section has an existing groove structure (V groove pattern with a Y-shaped equilateral triangle structure at the bottom of the light panel), and the first angle 755, The angle may be increased in order of the second angle 765 and the third angle 775. If the amount of light in the first direction is to be increased, the groove structure of the light panel has a cross section as described above with reference to FIG. 2, wherein the first, second, and third angles are the same, or the third, second, The angle may increase in the first angle order.

The above example is an example of a method for adjusting the groove angle of the light panel, and in various ways, the light panel may determine the shape of the groove structure in consideration of the position of the light panel.

In addition, according to another embodiment of the present invention, the angle of the groove structure may be determined in consideration of the position with the light emitting unit. For example, assuming that the light emitting portion is located only at the first corner, the groove structure positioned at the first position 730 of the light panel receives more light from the light emitting portion than the groove structure positioned at the second position 740 of the light panel. I can receive it. The angle of the groove structure positioned in the first position 730 and the angle of the groove structure positioned in the second position 740 may be implemented differently according to the direction in which light is emitted on the light panel. That is, the angle of the groove structure may be implemented differently in consideration of the amount of light reaching the groove structure on the light panel.

In addition, according to an embodiment of the present invention, the light panel plane is divided into a plurality of areas according to the distance, and a groove structure for each of the plurality of areas is formed in consideration of the amount of light to be generated on the divided areas. Can be determined. For example, an area on the light panel may be divided into first to fourth areas, and the groove angles of the groove structures of the first to fourth areas may have different values. The first region and the fourth region may be determined in consideration of the position of the light emitting unit, the distance between the light emitting unit and the groove structure, the irradiation direction of light on the light panel, and the like.

The location of the groove may be a groove line on the light panel 800 in which the groove structure is formed. The plurality of home lines on the light panel 800 may be determined based on a distance from the light emitter 850.

The light panel processor may determine the distance based on the light emitter 850 to form the groove line. As the distance from the light emitter 850 increases, the light reaching amount decreases so that the number of home lines for each region may be determined in consideration of this.

For example, based on the position of the light emitting unit 850, the positions of the light emitting unit are far from the first region 810, the second region 820, and the third region 830 on the light panel 800. Can lose. Groove lines should be formed in the first region 810, the second region 820, and the third region 830, and similar ranges of light may be generated in the first region 810, the second region 820, and the third region. If it is to be generated on 830, the density of the groove line on the region may be relatively higher in order of the first region 810, the second region 820, and the third region 830. That is, the first density 815, the second density 825, and the third density 835 may be implemented in order to increase the density of the home line.

The division of the region on the light panel 800 may be determined in consideration of the direction of light and the amount of light to be generated on the light panel 800.

According to the embodiment of the present invention, the light panel processor divides the surface of the light panel based on the position of the light emitting unit 850, user input information (light intensity information and light direction information to be emitted on the surface of the light panel), The density of the groove line and the angle of the groove structure can be set. The light panel processor sets a similar range of light intensity when dividing the surface of the light panel 800 based on the structure of the light panel 800, and sets a similar range of light direction to reflect light with similar characteristics. You can classify areas. When the characteristics of the light panel should be relatively accurate, a similar range of light illuminance may be set, and a similar range of light direction may be set relatively narrow. In addition, according to an embodiment of the present invention, since the influence of light on the light panel may decrease as the distance from the light emitting portion decreases, the division area may be set relatively wider as the distance from the light emitting portion increases.
