PURPOSE: A channel sign using an independent upper and lower extruded bar is provided to improve the decoration of a lighting state of the channel sign by generating sub light with various colors and directions from a light source of the extruded bar. CONSTITUTION: An upper extruded bar(10), a lower extruded bar(20), and a fixing plate(30) form an inner space. An extended protrusion(12,22) embeds a sub light source(40). The sub light source emits light from one side of the upper extruded bar and the lower extruded bar to the fixing plate. A channel character(50) is fixed on the surface of the fixing plate. The sub light source indirectly turns on the channel character.
