The frame 110 is typically formed of a frame member made of metal, and the corner portions where the two frame members meet to form a rectangular frame are finished and reinforced by a corner molding member.

The frame 110 has a mounting portion 112 and an insertion groove 114, as shown in the sectional view of FIG.

The mounting portion 112 is formed at an inner edge portion in the width direction of the frame 110. The mounting portion 112 includes an inner vertical surface 112a and an inner vertical surface 112a at one end in the width direction (for example, Quot; L "-shaped cross-sectional structure having an inner horizontal surface 112b that extends to the inner horizontal surface 112b. In other words, the inner horizontal surface 112b constitutes a widthwise inner edge portion of the frame 110, and the inner vertical surface 112a may be a surface protruding from the lateral outer end of the inner horizontal surface have.

The insertion groove 114 is formed so as to have a U-shaped cross-sectional structure, which is formed to be spaced outward in the width direction from the mounting portion 112a. The insertion groove 114 may be spaced apart from the inner vertical surface 112a by a distance corresponding to the thickness (width) of the protrusion 113 constituting the inner vertical surface 112a. In other words, the inner surface of the protrusion 113 serves as the inner vertical surface 112a with respect to the protrusion 113, and the outer surface of the protrusion 113 serves as the inner wall of the insertion groove 114 Lt; / RTI >

The insertion groove 114 may be formed to have a wider width than an entrance. This is to prevent the insertion protrusion 162, which will be described later, from being easily released after insertion.

The bottom surface of the LED module 150 is attached to the inner vertical surface 112a of the mounting portion 112 through a heat radiation tape. The LED module 150 includes a plurality of LED elements 154 arranged on a PCB board 152 having a predetermined length to irradiate light toward the light guide plate 130b.

Since the light guide plate 130b has a polymeric material such as PMMA, if the LED elements 154 or the LED module 150 and the light guide plate 130b directly come into contact with each other, The LED module 154 and the light guide plate 130b are spaced apart from each other by a predetermined distance because deformations (such as sulfur deformation) occur in the LED modules 130a and 130b.

The gap regulating protrusion 156 protrudes higher than the LED element 154 from the PCB substrate 152 so that the LED module 150, particularly the LED elements 154 and the light guide plate 130b, So as to be kept spaced apart.

In addition, the LED module 150 may have a longitudinally extending edge portion 158 of the PCB substrate 152 to have a "bend " structure for connector connection. In the conventional case, since the PCB substrate has a negative (-) structure, it is not easy to connect a connector for power supply. However, in the present invention, the edge portion of the PCB substrate 152 is designed to have a " The connection of the connector for power supply is facilitated.

1 to 5, the rear plate 120 is disposed such that an edge portion of the rear plate 120 is supported on the inner horizontal surface 112b of the mounting portion 112. As shown in FIG. The back plate 120 supports the back surface of the illuminator and maintains the flatness of the reflective sheet 130a disposed on the top.

The reflective sheet 130a is stacked on the back plate 120 to reflect the light of the LED module 150. FIG. The reflective sheet 130a is formed on the back surface of the light guide plate 130b and is scattered by the refraction in the light guide plate 130b to reflect the light directed toward the back side.

The light guide plate 130b is stacked on the reflective sheet 130a to induce light diffusion of the LED module 150. [ The light guide plate 130b is formed on the upper surface of the reflective sheet 130 and the rear surface of the diffusion plate 130c to refract the light emitted from the LED module 150, . The light guide plate 130b is spaced apart from the LED elements 154 by the gap adjusting protrusions 156 formed on the LED module 150. [

The diffusion plate 130c is stacked on the light guide plate 130b to diffuse the light. The diffusion plate 130c diffuses light emitted from the LED module 150 so as to uniformly irradiate the light toward the upper direction or the front direction when the light is scattered by the light guide plate 130b.

As shown in FIGS. 3 and 4, the gasket 160 covers and fixes the edge of the diffusion plate 130c. The gasket 160 includes insertion protrusions 162 and cover plates 164 and 166, Quot; cross-sectional shape. The cover plates 164 and 166 are provided with a first cover plate 164 and a second cover plate 166.

More specifically, the insertion protrusions 162 have a first protrusion 162a protruding downward to be spaced apart from each other at a predetermined interval, And a protrusion 162b. At this time, the interval between the first protrusions 162a and the second protrusions 162b is maintained at a certain level in the intermediate portion of the insertion protrusions 162 adjacent to the cover plates 164 and 166, and the cover plates 164 and 166, The first protrusions 162a and the second protrusions 162b are formed so that the distance between the first protrusions 162a and the second protrusions 162b is larger than the intermediate portion at the distal end portion of the insertion protrusions 162a, 162 may have a shape in which the distal end portion is thicker than the middle portion.

When the insertion protrusion 162 is inserted into the entrance portion of the insertion groove 114, the insertion protrusion 162 is made of a material having a certain elasticity (for example, plastic or metal) The first protrusions 162a and the second protrusions 162b are narrowed to reduce the total thickness of the protrusions 162a and 162b. Accordingly, when the gasket 160 is mounted or removed, that is, when the insertion protrusion 162 is inserted into the insertion groove 114 or separated from the insertion groove 114, It can be mounted and separated by force.

The first cover plate 164 has a structure that extends from the rear end of the insertion protrusion 162 toward the frame 110 and has various shapes such as a structure having a slope having a predetermined inclination or a flat surface, Lt; / RTI > The bottom or end of the first cover plate 164 comes into contact with the top surface 116 of the frame 110 when the gasket 160 is mounted.

The second cover plate 166 has a structure extending from the rear end of the insertion protrusion 162 toward the diffusion plate 130c. The second cover plate 166 has a horizontal surface that is thicker than the first cover plate 164 to support and fix the diffusion plate 130c. That is, the second cover plate 166 supports and fixes the back plate 120, the reflection sheet 130a, the light guide plate 130b, and the diffusion plate 130c having a sequentially stacked structure.

The shape of the second cover plate 166 may also be variously changed depending on the installation environment and the necessity.

Four gaskets 160 are provided and are finished and reinforced by the corner molding member 140 to be mounted in a quadrangular shape.

Fig. 6 shows another example of the shape of the gasket 160. Fig. 6 (a) is a perspective view of the gasket 160 and Fig. 6 (b) is a cross-sectional view.

6A and 6B, the shape of the insertion protrusion 162 of the gasket 160 is similar to that of FIGS. 3 and 4. However, in the case of the first cover plate 164 (Or length) is shorter than that of FIGS. 3 and 4 in that the upper part is flat and the lower part is sloped. In the case of the second cover plate 166, the shape of the top surface is different from that in the case of Figs. The upper surface of the second cover plate 166 has a stepped structure and is thicker than a portion of the second cover plate 166 that is away from the insertion protrusion 162 and has an inclined structure that becomes thinner toward the edge portion.
