  The surface illumination panel (200) plays a role of guiding emission incident from the frame side evenly on all sides.

  The guide frame (300) has a role of accommodating and enclosing a part of the end of the surface lighting panel (200), protecting the end of the surface lighting panel (200), and supporting them. In particular, a plurality of guide frames (300) are provided along the end track 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, but for convenience of explanation, it is assumed here that the guide frame (300) is arranged along a square locus.

  Further, a plurality of guide frames (300) are provided so as to be applicable according to the length of the entire frame of the surface illumination panel (200).

  In addition, the LED module (400) irradiates light to the frame side of the surface illumination panel (200) in a state where any one of the plurality of guide frames (300) is mounted inside the upper guide frame (300). It plays the role of lighting by releasing to one side.

  At this time, the LED module (400) receives a power supply from the outside and emits light, and a plurality of LED elements (420) and a lighting printed circuit board (410) on which a set number of LED elements (420) are mounted. Is included.

  The LED element (420) is mounted on the illumination printed circuit board (410) and emits light upon receiving power supplied from the illumination printed circuit board (410). Of course, the illumination printed circuit board (410) can be deformed into various shapes.

  The power module (500) is mounted on the inner side of the plurality of guide frames (300) where the LED element (420) is not mounted, and plays a role of supplying power to the LED module (400). .

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

  The power supply element (520) is mounted on the power supply printed circuit board (510), is supplied with power from the outside via the power supply printed circuit board (510), and the device is charged with the power. The power supply element (520) supplies power to the illumination printed circuit board (410) of the LED module (400).

  That is, the power printed circuit board (510) of the power module (500) is connected to the power cable (10) for receiving power supply from the outside, and the lighting printed circuit board (410) of the LED module (400) is The power supply printed circuit board (510) is connected to the power supply printed circuit board (510) via an energizing cable (20) for receiving power supply.

  On the other hand, the guide frame (300) is a metal material that can improve durability and strength in order to prevent deformation caused by heat generated in the LED element (420) or the power supply element (520). It has been produced.

  The LED element (420) is mounted on the illumination printed circuit board (410) by soldering, and the power supply element (520) is mounted on the power printed circuit board (510) by soldering.

  Further, the LED module (400) and the power supply module (500) are slid and inserted into the same guide frame (300) or another guide frame (300). Here, for convenience of explanation, it is assumed that the LED module (400) and the power supply module (500) are inserted into another guide frame (300).

  In particular, a plurality of guide frames (300) are provided, including an illumination guide frame (302) for slidingly inserting the LED module (400) and a power guide frame (304) for slidingly inserting the power supply module (500). Yes.

  Therefore, the soldering part of the LED element (420) and the illumination printed circuit board (410) can contact the inside of the illumination guide frame (302). In this case, when the soldering part is in contact with the lighting guide frame (302), a current flows through the lighting guide frame (302), which may cause an electric shock or damage the soldering part.

  In order to prevent this, in the apparatus according to this embodiment, the LED module (400) is inserted into the insulating guide member (600), and the insulating guide member (600) inserts a slide into the illumination guide frame (302). May be. Particularly, the insulation guide member (600) and the LED module (400) are positioned inside the illumination guide frame (302) because the insulation guide member (600) is restrained and inserted into the illumination guide frame (302). Fixed. At this time, the insulating guide member (600) may be provided with holes so as to correspond to the LED elements (420) of the LED module (400).

  Similarly, the soldered portion of the power printed circuit board (510) and the power element (520) can contact the inside of the power guide frame (304). In this case, when the soldering part is in contact with the power guide frame (304), a current flows through the power guide frame (304), which may cause an electric shock or damage the soldering part.

  In order to prevent this, in the apparatus according to the present embodiment, the power supply module (500) is inserted into the insulation guide member (600), and the insulation guide member (600) is slid into the power supply guide frame (304). It's okay. In particular, the insulation guide member (600) and the power supply module (500) are fixed in position inside the power supply guide frame (304) by the suppression guide insertion of the insulation guide member (600) into the power supply guide frame (304). The

  At this time, the insulating guide member (600) can be applied in various shapes such as the tube shape of the insulating material, but it is deformed inside the illumination guide frame (302) or the power supply guide frame (304), and inserted with restraint. Plastic materials that can be used can be used.

  In other words, the insulation guide member (600) protects the LED module (400) or the power supply module (500) by inserting the LED module (400) or the power supply guide frame (304) from the lighting guide frame (302) or the power supply guide frame (304). The module (400) or the power supply module (500) is inserted into the illumination guide frame (302) or the power supply guide frame (304).

  Here, for convenience of explanation, it is assumed that the insulating guide member (600) is inserted into the power supply guide frame (304) after the power supply module (500) is inserted.

  On the other hand, the guide frame (300) is arranged in a square trajectory on a plane, and as shown in FIGS. 1 and 3, a power guide is provided on the upper, lower and left ends of the surface illumination device (100). A frame (304) is arranged, and an illumination guide frame (302) is arranged at the right end.

  In particular, the adjacent illumination guide frame (302), power supply guide frame (304), and power supply guide frame (304) are connected by a corner frame (370).

  The corner frame (370) is provided so that the adjacent guide frames (302, 304) can be assembled and fixed and the adjacent guide frames (302, 304) can be easily separated. The corner frame (370) plays a role of guiding the arrangement so that the energization cable (20) for electrically connecting the LED module (400) and the power supply module (500) is not visible from the outside.

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

  The body (372) is finished so as to be positioned at a corner which is a connection portion between the adjacent illumination guide frame (302), the power supply guide frame (304), and the power supply guide frame (304). Of course, the body (372) can be deformed into various shapes.

  The first leg (374) is extended to the main body (310) and inserted into the illumination guide frame (302) and the power supply guide frame (304). That is, the first leg (374) is inserted into each of the illumination guide frame (302) and the power supply guide frame (304) constituting the vertical side of the guide frame (300). This prevents the LED module (400) slid into the illumination guide frame (302) and the power module (500) slid into the power guide frame (304) from being detached. Of course, the first leg (374) can be deformed into various shapes.

  Further, the second leg (376) extends from the main body (310) and is inserted into each of the power guide frames (304). 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). As a result, the power supply module (500) slide-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.

  In particular, the corner frame (370) can be formed so as not to be inserted beyond a certain level by limiting the degree of insertion into the illumination guide frame (302) and the power guide frame (304).

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

  On the other hand, the surface illumination panel (200) guides light incident on the boundary line side from the LED module (400) evenly to the entire side, and includes a diffusion sheet (210), a light guide sheet ( 220), a 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 laminated in order from the front side to the rear side. Of course, the diffusion sheet (210), the light guide sheet (220), the reflection sheet (230), and the back cover (240) can be laminated in layers as required. Here, for convenience of explanation, it is assumed that 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 element (420) from the frame side and plays a role of guiding the emission of light over the entire surface.

  The diffusion sheet (210) performs the function of internally scattering and diffusing the light emitted from the LED element (420) of the LED module (400), but the LED generates a light from a single point. Therefore, when the LED is used as a light source as it is, exposure of the light source and glare phenomenon can occur. Therefore, in order to prevent this, the diffusion sheet (210) is provided.

  Here, the diffusion sheet (210) may be manufactured by extruding polystyrene (polystyrene, PS) or polycarbonate (polycarbonate, PC), but the diffusion sheet (210) has a different refractive index. Bubbles or diffusing agents (not shown) are distributed, and the bubbles or diffusing agents refract and reflect the light incident on the diffusion sheet (210).

  In particular, when bubbles and a diffusing agent (not shown) are sufficient inside the diffusion sheet (210), the light incident on the frame of the diffusion sheet (210) is emitted to the outside of the front side of the diffusion sheet (210). The light intensity becomes uniform and the divergence angle increases.

  The reflection sheet (230) is disposed on the rear side of the light guide sheet (220) and serves to reflect light on all sides. That is, the light emitted from the LED element (420) flows into the light guide sheet (220) from the boundary line on one side of the light guide sheet (220), and this light is transmitted to the front side of the light guide sheet (220). Released to the rear side. At this time, the light emitted to the rear side of the light guide sheet (220) is reflected by the reflection sheet (230) and guided to the front side of the light guide sheet (220). Thereby, the illumination intensity 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 and diffuses as a whole while passing through the diffusion sheet (210), thereby preventing glare.

  The back cover (240) is disposed on the rear side of the reflection sheet (230), and is made of an opaque material so that light is concentrated and emitted to the front side of the light guide sheet (220). That is, the light emitted from the LED element (420) flows into the light guide sheet (220) from the boundary line on one side of the light guide sheet (220), and this light is transmitted to the front side of the light guide sheet (220). Released to the rear side. At this time, a part of the light emitted to the rear side of the light guide sheet (220) is reflected by the reflective sheet (230) and guided to the front side of the light guide sheet (220), but the remaining light is It is emitted to the rear side of the reflection sheet (230). The light emitted to the rear side of the reflection sheet (230) is reflected by the back cover (240) and emitted from the front side of the reflection sheet (230) and the front side of the light guide sheet (220), and then the diffusion sheet (210). The light is evenly emitted through the light to illuminate the room.

  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.

  On the other hand, heat is generated in the light guide sheet (220) by directly flowing light from the LED elements (420). Since the front side is bonded to the diffusion sheet (210), heat is accumulated, and the rear side is bonded to the reflection sheet (230), so that heat is accumulated and the heat is not released.

  In order to prevent this, the light guide sheet (220) is formed with an embossed valve (222) protruding on the front side surface and the rear surface. Here, the embossing valve (222) protruding to the rear side of the light guide sheet (220) minimizes the contact area with the reflective sheet (230), protects the reflective sheet (230), and externally The air flow smoothly protrudes in a triangular pyramid shape. Of course, the embossing valve (222) protruding to the rear side of the light guide sheet (220) can be applied to various shapes that minimize the contact area with the reflection sheet (230).

  Then, the embossing valve (222) protruding from the front side surface of the light guide sheet (220) can be formed in a convex embossed shape so that light spreads uniformly and flows into the diffusion sheet (210). Of course, the embossing valve (222) protruding from the front side surface of the light guide sheet (220) can be applied to various shapes so that the light spreads evenly.

  Furthermore, the diffusion sheet (210), the light sheet (220), the reflection sheet (230), and the back cover (240) laminated to constitute the surface lighting panel (200) are configured to be the same size and completely. Guided to be overlaid. For this reason, the body (372) of the corner frame (370) has the vertices of the diffusion sheet (210), the light guide sheet (220), the reflection sheet (230), and the back cover (240) of the surface illumination panel (200). A rearranging corner member (371) is provided so as to correspond to. The rearrangement corner member (371) plays a role of guiding the diffusion sheet (210), the light guide sheet (220), the reflection sheet (230), and the back cover (240) to be completely stacked. Needless to say, the sort corner member (371) can be deformed into various shapes.

  The guide frame (300) that constitutes the frame of the surface illumination device (100) is formed by stacking a diffusion sheet (210), a light guide sheet (220), a reflection sheet (230), and a back cover (240). These are supported and protected by accommodating the ends of the surface lighting panel (200).

  In particular, the guide frame (300) includes a main body (310), an insertion space (320), a support rib (330), and a push stopper (340).

  The main body (310) forms the outer shape of the guide frame (300) and forms the frame of the surface illumination device (100). Of course, the main body (310) can be deformed into various shapes.

  The insertion space (320) slides the LED module (400), the insulation guide member (600), or the power supply module (500) as a space that is axially generated inside the main body (310). It can be inserted. In particular, the insertion space part (320) is formed so that the light of the LED element (420) is diverged to the light guide sheet (220) side and is opened to the surface illumination panel (200) side. At this time, the illumination guide frame (302) and the power supply guide frame (304) can be manufactured in the same shape so that compatibility is possible.

  Further, the support rib (330) is extended alongside the main body (310) so as to form an accommodation groove (332) for accommodating the end of the surface illumination panel (200). Thus, the support rib (330) supports the upper side and the lower side of the surface illumination panel (200) in contact with each other. Of course, the support rib (330) can be deformed into various shapes. And the depth of the accommodation groove part (332) is not specifically limited.

  The push stopper (340) plays a role of pressing the surface illumination panel (200) that protrudes from the support rib (330) and is accommodated in the accommodation groove (332). At this time, the push stopper (340) may protrude from the inner side surfaces of the opposing support ribs (330), or may be formed to protrude from one of the support ribs (330). The push stopper (340) maintains a state in which the diffusion sheet (210), the light guide sheet (220), the reflection sheet (230), and the back cover (240) forming the surface illumination panel (200) are stacked. It plays a role in preventing spillage. Of course, the push stopper (340) is not limited in shape and number.

  The guide frame (300) is partitioned separately from the receiving groove (332), and the sorting groove (350) for receiving and sorting the power cable (10) connecting the external power source and the power supply module (500). Can be formed. The rearrangement groove (350) is formed in the main body (310) along the axial direction.

  FIG. 11 is an enlarged cross-sectional view of a main part of a surface illumination device with a built-in power source according to another embodiment of the present invention, and FIG. 12 is a front view showing an illumination state of a surface illumination panel according to another embodiment of the present invention. It is.

  Referring to FIGS. 11 and 12, a surface lighting device (100) with a built-in power source according to another embodiment of the present invention includes a surface lighting panel (200), a guide frame (300), an LED module (400), a power source. A module (500) and an insulating guide member (600) are included.

  The guide frame (300), LED module (400), power supply module (500), and insulating guide member (600) are replaced with those described above.

  As described above, the surface illumination panel (200) includes the diffusion sheet (210), the light sheet (220), the reflection sheet (230), and the back cover (240).

  In particular, the light guide sheet (220) has a rear side so that the illuminance (illuminance) at a specific part of the light emitted to the entire front side while passing through the inside from the frame is processed to be brighter or darker. Can be provided with a pattern forming portion (224).

  The light emitted from the LED element (420) collides with the translucent pattern forming part (224) formed on the rear side in the process of transmitting the light incident on the inside of the light guide sheet (220). After being reflected, the light is emitted to a specific area on the front side corresponding to the pattern forming portion (224). Thereby, the light guide sheet (220) shines brighter than the light emitted from the position where the pattern forming portion (224) is not formed, from the position where the pattern forming portion (224) is formed.

  On the contrary, the light guide sheet (220) does not have the pattern formation part (224) of only a specific area on the rear side, so that the light forms the pattern formation part (224) through the area. It is set relatively darker than the area.

  Thereby, the light guide sheet (220) can ensure the advertising effect and visibility by making the illuminance (illuminance) of the emitted light different according to the formation region of the pattern forming portion (224). it can.

  At this time, the pattern forming unit (224) is arranged along a character, a pattern, or a locus desired by the user.

  At this time, the pattern forming portion (224) is irradiated with laser on the rear side of the light guide sheet (220), so that the portion becomes translucent.

  Of course, the pattern forming unit (224) can be formed in various shapes such as at least one of a character, a picture, a pattern, and a pattern, or a combination thereof.

  Reference numerals in the drawings in which description is omitted are interpreted in place of those described above.
