     DETAILED DESCRIPTION OF THE INVENTION 
       [0027]    Hereafter, LED-illuminated signboard metallic-cased of the present invention is described in detail by referring to the attached drawings. 
         [0028]      FIG. 1  is a view of LED-illuminated signboard metallic-cased according to an embodiment of the present invention, and  FIG. 2  is a view of the front metal panel of LED-illuminated signboard metallic-cased of  FIG. 1 . 
         [0029]    As shown in FIGS., the present embodiment of LED-illuminated signboard metallic-cased ( 10 ) include base frame ( 120 ), LED module part ( 140 ) and front metal panel ( 160 ). 
         [0030]    The base frame ( 120 ) perform the role that fixate the overall shape of LED-illuminated signboard metallic-cased ( 10 ), the shape of base frame ( 120 ) is not limited. For example, the base frame ( 120 ) can be formed by multiple frames, such as triangular or rectangular frame. In the following description for convenience, but described in the case focused on the base frame ( 1   20 ) of square type are in progress. 
         [0031]    Base frame ( 120 ) can be formed the top surface opened, additionally in including side part and bottom part. Meanwhile, the base frame ( 120 ) can further include tightening means fixed or hanged to a wall. For example, the base frame ( 120 ) can be immobilizing minor part of the upper on the wall through bolts and so on, and hung on a protrusion or a hook by forcing the upper of the side part to hang the ring and the strap associated with the ring said. 
         [0032]    Meanwhile, the base frame ( 120 ) can be blocked many spaces by installing a large number of multiple barrier inside. In addition, the base frame ( 120 ) can be placed channel character frame by installing a large number of multiple barrier said inside. 
         [0033]    Base frame ( 120 ) of the material is not limited. For example, the base frame ( 120 ) can be of metal or plastic. 
         [0034]    LED module part ( 140 ) consists of a plurality of LED modules, and acts as a light source emitting. LED module part ( 140 ) is placed in the base frame ( 120 ), if it can be produced needed performance base frame ( 1   20 ) is not limited on the bottom or the sides. Additionally, LED module part ( 140 ) can be formed on the shape of at least one or more in the middle of letters, shapes, patterns or symbols to represent. However, hereinafter for convenience of description, as shown in  FIG. 2 , it is described in focusing the case that LED module part ( 140 ) is formed on ‘A’ shape. 
         [0035]    For example, LED module part ( 140 ) have the bulkhead installed on the ‘A’ shape, and can be placed inside in the bulkhead said. In addition, LED module part ( 140 ) itself without having the bulkhead above can be formed on ‘A’ shape. 
         [0036]    LED module part ( 140 ) can include PCB circuit boards (not shown) formed a circuit that provides power and electrical signals to LED modules and LED modules mounted on said PCB circuit boards. In addition, said PCB circuit board can further include Control Part (not shown) controlling at least one of the lighting sequence, lighting speed, Flashing, blinking rate or color. Meanwhile, said LED modules can be at least one of Red LED chips, green LED chips and the blue LED chip. 
         [0037]    Meanwhile, LED module part ( 140 ) can be packaged waterproofer (not shown). In this case, moisture and dust are prevented to entering into LED module part ( 140 ), it is possible to extend the life of that. 
         [0038]    Front metal panel ( 160 ) is the front of the sign board, and is coupled to the front of base frame ( 120 ). In addition, the plurality of microscopic holes is formed at least on one part in the metal front panel ( 160 ). Specifically, microscopic holes ( 162 ) can be formed in the corresponding position that LED module part ( 140 ) is placed. 
         [0039]    For example, when LED module part ( 140 ) is placed the ‘A’ shape inside the base frame ( 120 ), microscopic holes ( 162 ) can be formed to achieve the same shape to said ‘A’ shape at the surface corresponding to LED module part ( 140 ) on the state combined with base frame ( 120 ). 
         [0040]    In the past, if you are using metal to the panel, there are problems that metals can not be used as the front panel because light source such as LED illumination can not be placed inside depending on nature of light passing in the metal. 
         [0041]    But on embodiments of the present invention it is characterized that light irradiated from the light source placed inside can be permeable front part by being formed a plurality of microscopic holes in front of the front panel made of metal. 
         [0042]    Front metal panel ( 160 ) is manufactured by a metal material. For example, a metal front panel ( 160 ) can be prepared manufactured by aluminum, iron or stainless steel, etc. 
         [0043]    Also in this embodiment of LED-illuminated signboard metallic-cased ( 10 ), microscopic holes ( 162 ) is formed generally small that the human eye identify difficultly, for example, micrometer [μm] to hundreds of micrometer [μm]. 
         [0044]    Of course, LED-illuminated signboard metallic-cased ( 10 ) can be formed few microseconds [μm] less or few millimeters [mm] larger in size, but it is so closely related production costs, performance effects to implement, and so on. In other words, if microscopic holes ( 162 ) is formed as the size of few millimeters [mm] range (which is understood later in the process), performance effect is reduced because the image of cell that is produced is large. Conversely, when LED-illuminated signboard metallic-cased ( 10 ) is manufactured with less than a few micrometers [μm] it is cost to form microscopic holes ( 162 ), furthermore it is accompanied by several problems that the thickness of front metal panel ( 160 ) must be thin because of the problem of LED light projecting and the viewing angle narrowed. 
         [0045]    Therefore on this LED-illuminated signboard metallic-cased ( 10 ), microscopic holes ( 162 ) that is formed 3 [mm] or less will have a sense. However, in this embodiment it is described in focusing the case that microscopic holes ( 162 ) are formed 50 micrometer [μm]. 
         [0046]      FIG. 3  is a view to explain an embodiment of forming microscopic holes on the front metal panel of LED-illuminated signboard metallic-cased of  FIG. 1 , and  FIG. 4  is a view to explain another embodiment of forming microscopic holes on the front metal panel of LED-illuminated signboard metallic-cased of  FIG. 1 . 
         [0047]    As shown in  FIG. 3 , in this embodiment of LED-illuminated signboard metallic-cased ( 10 ), microscopic holes ( 162 ) are formed by projecting the laser beam from the laser machine for a certain period of time; 0.1 millisecond [msec] as shown in arrow in this embodiment. 
         [0048]    Of course, this control process is required very precise control of machining. In other words in this embodiment, to should be made precise control is very natural because the distance to the neighboring microscopic hole ( 162 ) is 100 micrometer [μm] as twice to 50 micrometer [μm] of microscopic hole ( 162 ) diameter. 
         [0049]    Besides in this embodiment of LED-illuminated signboard metallic-cased ( 10 ), as shown in  FIG. 4 , microscopic hole ( 162 ) according to this embodiment can be even formed by introducing etching process. 
         [0050]    When microscopic holes ( 162 ) is manufactured by etching process, first of all as shown in arrows a preliminary home ( 162   s ) for microscopic holes ( 162 ) is formed by firing a laser beam of the laser machine above the top of metal ( 160   m ) for front panel. Since then, microscopic holes ( 162 ) is formed by being formed Etching Home ( 162   e ) through performing etching process to a certain depth at the bottom of Preliminary home ( 162   s ). It is possible to form better shape as microscopic hole ( 162 ) which is weak shape by manufacturing with the laser machine. 
         [0051]    In addition, this processes are also possible to perform the change depending on the needs, and Preliminary home ( 162   s ) and etching Home ( 162   e ) all can be formed by etching process. 
         [0052]    Microscopic hole ( 162 ) formed by this process is filled with transparent material depending on the needs, or the surface of metal ( 160 m) for front panel is also possible to be coated. However, because this process is related to heighten performance effect according to good passing of LED light-emitting it is preferably carried out in state well-considered many situations. 
         [0053]    This process is the processing method used for manufacturing microscopic hole ( 162 ) to metal when the thickness of the metal is relatively thick and machining is difficult through the laser beam. Of course, it is possible to process non-strong natured metal. 
         [0054]    LED-illuminated signboard metallic-cased ( 10 ) of the present embodiment can further include the material that pass the light between base frame ( 120 ) and metal front panel ( 160 ). The said material of passing light perform the function to prevent infiltration of dust or moisture through microscopic holes ( 162 ). The said material of passing light, for example, is preferable the resin of passing light such as acrylic resin. The said material of passing light can be seated between sheets or attached to the front or rear of microscopic holes ( 162 ). 
         [0055]      FIG. 5  is a concept view of separating LED-illuminated signboard metallic-cased according to an embodiment of the present invention.
