The present invention relates to an LED assembly and products using the same. More specifically, the present invention relates to an LED assembly having improved discernibility from the far distance and near distance and from the front and sides, which is covered with a light-passing unit having a thin-film light-passing part and a thick-film light-passing part such that scattering of light is prevented and in which the light irradiation range is specified by the size of the light-passing unit such that light can penetrate far from the thin-film light-passing part but, even so, glare directly in front of the front surface of the LED is softened and, because the medium in the thick-film light-passing part is thick, some of the light passing through the medium is reflected on the inside and the light can also reach the side surfaces. The present invention also relates to signboards and traffic safety display boards using the LED assembly. |
