PURPOSE: An LED(Light Emitting Diode) channel sign is provided to prevent a resin from being separated from a frame by forming one or more fixing units on the inner surface of the frame. CONSTITUTION: A resin is spread inside a frame(100). The frame has one or more fixing units(120). The fixing unit is united with the resin in order to prevent the resin from being separated from the frame. A resin plate(115) divides the inner space of the frame into a resin formation layer and an air layer. A PCB(Printed Circuit Board) is arranged on the air layer. An LED(140) is installed on the PCB. A sub frame(110) is detachably combined with the frame. |
