A LED sign includes at least a light guider, which is shaped as a sign word, defining an illumination channel therealong and a plurality of LED illuminators spacedly disposed underneath the light guider at a light diffusion distance for generating lights towards the illumination channel in such a manner that the lights are accumulated within the illumination channel to highlight the light guider so as to form a continuous illumination effect as a neon light effect.
