The surface lighting panel 200 serves to uniformly guide the light incident from the edge side to the front side.

The guide frame 300 serves to protect and support the edge of the surface lighting panel 200 by receiving and wrapping a part of the edge of the surface lighting panel 200. In particular, a plurality of guide frames 300 are provided along edge trajectories of the surface illumination panel 200.

At this time, the guide frame 300 may be arranged along a circular or polygonal locus on a plane, and it is assumed that the guide frame 300 is disposed along a quadrangular locus for convenience.

In addition, the guide frame 300 may be provided in a plurality of ways so as to be applicable to the entire length of the frame of the surface lighting panel 200.

The LED module 400 is mounted inside one or more guide frames 300 of the plurality of guide frames 300 and emits light toward the edge of the surface lighting panel 200 to be emitted to one side. do.

At this time, the LED module 400 includes one or more LED elements 420 that receive power from the outside and emit light, and an illuminated printed circuit board 410 that mounts the set number of LED elements 420.

The LED device 420 is mounted on the illumination printed circuit board 410 and supplies the supplied power to the illumination printed circuit board 410 to emit light. Of course, the illuminated printed circuit board 410 can be deformed into various shapes.

The power supply module 500 is mounted inside one or more guide frames 300 without the LED device 420 to supply power to the LED module 400.

In particular, the power supply module 500 includes a power supply element 520 and a power printed circuit board 510.

The power source device 520 is mounted on the power source printed circuit board 510 and receives power from the outside through the power source printed circuit board 510 or receives power from the outside. The power supply element 520 supplies power to the illumination printed circuit board 410 of the LED module 400.

That is, the power supply printed circuit board 510 of the power supply module 500 is connected to the power supply cable 10 in order to receive power from the outside, and the illumination printed circuit board 410 of the LED module 400 is connected to the power supply print circuit board And is connected to the power printed circuit board 510 via the energizing cable 20 in order to receive power from the substrate 510.

Meanwhile, the guide frame 300 is made of a metal material to improve durability and strength to prevent deformation from heat generated from the LED device 420 or the power source device 520.

The LED element 420 is soldered to the printed circuit board 410 and the power supply element 520 is soldered to the power printed circuit board 510.

In addition, the LED module 400 and the power supply module 500 are slidably inserted into the same guide frame 300 or another guide frame 300. For convenience, it is assumed that the LED module 400 and the power supply module 500 are inserted into another guide frame 300.

More specifically, the guide frame 300 includes a plurality of guide frames 300, and includes an illumination guide frame 302 for slide-inserting the LED module 400 and a power guide frame 304 for slidably inserting the power supply module 500.

Therefore, the solder portions of the LED element 420 and the illuminated printed circuit board 410 can be brought into contact with the inside of the illumination guide frame 302. In this case, when the soldered portion is in contact with the illumination guide frame 302, a current may flow through the illumination guide frame 302, causing an electric shock, or the soldered portion may be broken.

In order to prevent this, the LED module 400 is inserted into the insulation guide member 600, and the insulation guide member 600 can be slidably inserted into the illumination guide frame 302. The insulation guide member 600 and the LED module 400 can be fixed in the interior of the illumination guide frame 302 by inserting the insulation guide member 600 into the illumination guide frame 302. At this time, the insulation guide member 600 can pass holes corresponding to the LED elements 420 of the LED module 400.

Likewise, the solder portions of the power supply printed circuit board 510 and the power supply elements 520 may be in contact with the inside of the power supply guide frame 304. In this case, when the solder portion contacts the power supply guide frame 304, a current may flow through the power supply guide frame 304, causing an electric shock, or the soldered portion may be broken.

To prevent this, the power supply module 500 is inserted into the insulated guide member 600, and the insulated guide member 600 is slidably inserted into the power supply guide frame 304. The insulating guide member 600 and the power supply module 500 can be fixed in the power supply guide frame 304 by inserting the insulating guide member 600 into the power supply guide frame 304. [

The insulation guide member 600 may be made of a plastic material that can be deformed and inserted into the illumination guide frame 302 or the power guide frame 304 in various ways.

The insulated guide member 600 inserts and protects the LED module 400 or the power supply module 500 from the illumination guide frame 302 or the power source guide frame 304 and protects the LED module 400 Or the power supply module 500 is inserted into the lighting guide frame 302 or the power supply guide frame 304. [

For convenience, the insulated guide member 600 is illustrated as being inserted into the power supply guide frame 304 after insertion of the power supply module 500.

1 and 3, the power supply guide frame 304 is disposed on the upper side, the lower side and the left side edge of the plane illumination device 100, and the right side And the illumination guide frame 302 is disposed at the edge.

Particularly, the neighboring illumination guide frame 302, the power supply guide frame 304, and the power supply guide frame 304 are connected by the corner frame 370.

The corner frame 370 is provided to assemble and fix neighboring guide frames 302 and 304 and to easily separate neighboring guide frames 302 and 304. The corner frame 370 serves to align and guide the current-carrying cable 20 electrically connecting the LED module 400 and the power supply module 500 in a non-exposed manner.

At this time, the corner frame 370 includes a body 372, a first leg 374, and a second leg 376.

The body 372 is positioned at a corner of a connecting portion between the neighboring illumination guide frame 302 and the power source guide frame 304 and the power source guide frame 304 to perform a finishing process. Of course, the body 372 can be deformed into various shapes.

The first leg 374 extends from the main body 310 and is inserted into the illumination guide frame 302 and the power supply guide frame 304, respectively. That is, the first leg 374 is inserted into each of the illumination guide frame 302 and the power source guide frame 304 constituting the longitudinal side of the guide frame 300. Thus, the LED module 400 inserted into the illumination guide frame 302 and the power supply module 500 inserted into the power supply guide frame 304 are prevented from being separated. Of course, the first leg 374 can be deformed into various shapes.

The second legs 376 extend from the main body 310 and are inserted into the power supply guide frames 304, respectively. That is, the second leg 376 is inserted into each of the power supply guide frames 304 constituting the lateral side of the guide frame 300. Thus, the power supply module 500 inserted into the power supply guide frame 304 is prevented from being detached. Of course, the second leg 376 can be deformed into various shapes.

Particularly, the corner frame 370 can be formed so as not to be inserted more than a certain distance by limiting the degree of insertion into the illumination guide frame 302 and the power supply guide frame 304.

Of course, the corner frame 370 can be deformed into various shapes.

The planar illumination panel 200 uniformly emits light incident from the LED module 400 to the front side of the LED module 400 through the diffusion sheet 210, the light guide sheet 220, the reflective sheet 230, And a back cover 240.

In particular, the diffusion sheet 210, the light guide sheet 220, the reflection sheet 230, and the back cover 240 are stacked in order from the front side to the back side. Of course, the diffusion sheet 210, the light guide sheet 220, the reflection sheet 230, and the back cover 240 may each be stacked one layer or more as needed. For convenience, the diffusion sheet 210, the light guide sheet 220, the reflection sheet 230, and the back cover 240 are provided one by one.

At this time, the light guide sheet 220 receives the light emitted from the LED device 420 from the edge side, and induces light to be emitted across the entire surface.

The diffusion sheet 210 functions to scatter and diffuse the light emitted from the LED device 420 of the LED module 400. Since the LED is a point light source that generates light at one point, When used as a light source, the light source may be exposed or glazed. To prevent this, a diffusion sheet 210 is provided.

Here, the diffusion sheet 210 can be manufactured by extrusion molding polystyrene (PS) or polycarbonate (PC). In the diffusion sheet 210, bubbles or diffusers having different refractive indices And the bubbles or diffusing agent refracts and reflects the light incident on the diffusion sheet 210.

Particularly, when bubbles or a diffusing agent (not shown) are sufficient in the diffusion sheet 210, when the light incident from the rim of the diffusion sheet 210 is emitted to the outside of the front side of the diffusion sheet 210, The intensity becomes uniform and the divergence angle becomes large.

The reflective sheet 230 is disposed on the rear side of the light guide sheet 220 to reflect light toward the front side. That is, light emitted from the LED device 420 flows into the light guide sheet 220 from one side edge of the light guide sheet 220, and the light is emitted to the front and rear sides of the light guide sheet 220. At this time, the light emitted to the rear side of the light guide sheet 220 is reflected by the reflection sheet 230 and is guided to the front side of the light guide sheet 220. As a result, the lightness of the light emitted to the front side of the light guide sheet 220 is improved.

The light emitted to the front side of the light guide sheet 220 spreads evenly throughout the diffusion sheet 210, thereby preventing glare.

The back cover 240 is disposed on the rear side of the reflective sheet 230 and is made of an opaque material so that the light is intensively emitted to the front side of the light guide sheet 220. That is, light emitted from the LED device 420 flows into the light guide sheet 220 from one side edge of the light guide sheet 220, and the light is emitted to the front and rear sides of the light guide sheet 220. At this time, a part of the light emitted to the rear side of the light guide sheet 220 is reflected by the reflection sheet 230 and is guided to the front side of the light guide sheet 220, but the remaining light is emitted to the rear side of the reflection sheet 230. Light emitted to the rear side of the reflective sheet 230 is reflected by the back cover 240 and is emitted to the front side of the reflective sheet 230 and the front side of the light guide sheet 220 and then uniformly emitted through the diffusion sheet 210, .

In particular, the size and number of the diffusion sheet 210, the light guide sheet 220, the reflection sheet 230, and the back cover 240 are not limited.

The light guide sheet 220 generates heat by directly introducing light from the LED element 420. The light guide sheet 220 is formed by stacking the front side of the diffusion sheet 210 and the rear side of the diffusion sheet 210, So that heat can not be released.

In order to prevent this, the light guide sheet 220 has embossed protrusions 222 protruding from the front side and the back side. The embossed protrusion 222 protruding from the rear surface of the light guide sheet 220 minimizes the contact area with the reflective sheet 230 to protect the reflective sheet 230 and protrudes in an approximately triangular- . Of course, the embossed protrusion 222 protruding from the rear surface of the light guide sheet 220 can be applied to various shapes that minimize the contact area with the reflective sheet 230.

The embossing portion 222 protruding from the front surface of the light guide sheet 220 may be formed in a convex emboss shape so that the light spreads uniformly and flows into the diffusion sheet 210. Of course, the embossing portion 222 protruding from the front surface of the light guide sheet 220 can be applied in various shapes so that the light spreads evenly.

In addition, the diffusion sheet 210, the light guide sheet 220, the reflection sheet 230, and the back cover 240 stacked to form the surface lighting panel 200 can be guided to be completely overlapped with each other in the same size. The body 372 of the corner frame 370 is formed to correspond to each vertex of the diffusion sheet 210, the light guide sheet 220, the reflection sheet 230 and the back cover 240 of the surface lighting panel 200 And has an alignment corner member 371. The alignment corner member 371 serves to guide the diffusion sheet 210, the light guide sheet 220, the reflection sheet 230, and the back cover 240 to completely overlap. Of course, the alignment corner member 371 can be deformed into various shapes.
