Description

Panel for surface light source

The present invention relates to a display system, and more particularly, to a panel for a surface light source in which a main-dot and an auxiliary-dot for illuminating light diffusion are uniformly formed.

In general, instead of horizontally or vertically installing a plurality of fluorescent light sources on the back side of the diffuse reflection panel, a surface light source device is disposed so as to contact the light source on the end surface of the surface light source panel.

That is, as the conventional technology having the above configuration, Japanese Patent Application Laid-Open No. 57-128383 (name: surface lighting device), Korean Patent Publication No. 96-13210 (Name: Display System) and Domestic Patent Publication No. 94-1116 (named: surface light source panel) (hereinafter referred to as "prior art"). The prior arts print dots, which are light diffusing reflectors, to diffuse illumination light emitted from a light source onto an entire surface of the panel on one or both surfaces of the panel for surface light sources.

However, in the prior art as described above, the luminance of the illumination light generated from the light source is not uniform because the space between the dots is large. That is, the panel surface to which the image film was attached was not bright. Therefore, in order to solve such a problem, the dots are printed on both sides of the panel, but this also has a problem that adversely affects the image due to the defect that the dot printing network is displayed on the image film as it is during the lighting advertisement and the light poster advertisement. This was expected.

Accordingly, an object of the present invention is to provide a panel for a surface light source that can implement a uniformity of brightness and illuminance of illumination light by printing separate sub-dots in the space portion between the dots printed on the panel.

Another object of the present invention is to provide a panel for a surface light source that can uniformly diffuse the illumination light of the lamp by uniformly forming the main-dot and sub-dots in the surface light source panel.

In order to achieve the above object, the display system of the present invention includes a flat panel panel for surface light source, a lamp installed at one edge of the panel to irradiate illumination light to the end surface of the panel, and formed in the panel to A main-dots for allowing illumination light to diffuse to the entire surface of the panel, and a reflecting plate attached to the bottom of the panel to reflect the illumination light, wherein the space between the main-dot and the main-dot is A plurality of sub-dots having a diameter smaller than the diameter of the main-dot are formed, and the sub-dots are formed in a hexagonal shape spaced apart at predetermined intervals along the circumference of the main-dot.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings. In the following description, it should be noted that only parts necessary for understanding the operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to obscure the subject matter of the present invention.

1 shows a configuration of a side survey display system according to an embodiment of the present invention. In the drawing, the panel 10 for the surface light source forms a flat plate having a rectangular shape, and at one edge of the panel 10, a lamp 16 for emitting a predetermined illumination light is provided by a protective cap 18. In addition, a milky white or silver reflector 12 is attached to a rear surface of the panel 10, and the reflector 12 reflects the illumination light so that the illumination light emitted from the lamp 16 is incident toward the front as much as possible without falling back. Let's do it. In addition, the front surface of the panel 10 is attached to the image film 14, the advertisement to be printed.

Here, the configuration of the surface light source panel of the present invention in the side irradiation display system will be described in detail with reference to FIGS. 2 and 4.

2 and 3 are schematic views showing the configuration of the surface light source panel according to the first embodiment of the present invention, a plurality of main-dots 100 having the same diameter on the front surface of the panel 10a regularly It is printed so that the illumination light irradiated from the lamp 17 can be diffused to the entire surface of the panel 10a. That is, the main-dots 100 are printed in an upward direction while maintaining a constant distance from each other. In addition, a plurality of sub-dots 102 having a diameter smaller than the diameter of the main-dot 100 are spaced apart while maintaining a predetermined interval in the space portion between the main-dot 100 and the main dot 100. Is formed. That is, the sub-dots 102 are printed in a hexagonal shape along the circumferential surface at a certain distance from the circumference of the main-dot 100. At this time, the auxiliary-dots 102 printed as above allow the illumination light irradiated from the lamp 16 to be uniformly spread on the entire surface of the panel 10a, that is, the illumination light is applied to the main-dot 100 and the main. -To spread even in the space between the dots (100). Here, the main-dot 100 and the sub-dots 102 may be printed on the rear surface of the panel 10a in the same manner as described above.

4 and 5 are schematic views showing the configuration of a panel of a surface light source according to a second preferred embodiment of the present invention, the front surface of the panel (10b) a plurality of main-dots gradually smaller diameter toward the upper direction The 110 are printed regularly, so that the illumination light emitted from the lamp 16 can be diffused to the entire surface of the panel 10b. That is, since no illumination light is transmitted to the surface of the panel 10b that is far from the lamp 16, the diameter of the main-dot 110 is printed larger and larger. In addition, a plurality of sub-dots 112 having a diameter smaller than the diameter of the main-dot 110 are spaced apart from each other in the space portion between the main-dot 110 and the main dot 110. Is formed. That is, the auxiliary-dot 112 is printed in a hexagonal shape along the circumferential surface at a predetermined distance with respect to the circumference of the main-dot 110. At this time, the auxiliary-dots 112 printed as described above allow the illumination light irradiated from the lamp 16 to be uniformly spread on the entire surface of the panel 10b, that is, the illumination light is main-dot 110 and the main. -To spread even in the space between the dots (110). Here, the main-dot 110 and the sub-dot 112 may be printed on the rear surface of the panel 10b in the same manner as described above.

Hereinafter, the diffused state, luminance, and illuminance of the illumination light between the panel for surface light source printed with the sub-dots and the main-dot according to the first and second embodiments of the present invention and the panel for conventional surface light source printed with only the main-dot Experimental results of comparing the characteristics with each other are shown in the following table.

As shown in the above table, the auxiliary-dot of the present invention can be seen that there is no significant difference in function even if the shape is changed into a square, triangle, octagon, oval, etc.

And the configuration trajectory of the sub-dots may have any trajectory out of the hexagon, and this change is only to the extent that it can be easily drafted from the present invention and belongs to the technical scope of the present invention.

As described above, the present invention can realize good brightness and illuminance without printing the shadow of the dots on the image film by printing the sub-dots in the space between the dots. And the surface light source panel of the present invention can uniformly diffuse the illumination light irradiated from the lamp on the entire surface of the panel.
