Abstract: The invention relates to an illuminant device. The illuminant device of the invention comprises a base, a connecting portion, a containing portion, a sheet-like light source and a closing element. The base has a rib. The connecting portion has a first combining portion, and the shape of the first combining portion matches with the shape of the rib. The connecting portion is disposed on the rib by using the first combining portion. The containing portion has a second combining portion and at least one transparent surface. The containing portion is disposed on the rib by using the second combining portion and connects to the connecting portion. The sheet-like light source is disposed in the containing portion and the light comes out from the transparent surface. The closing element is used to close the containing portion. Whereby, the illuminant device of the invention can be set up at any location to be marked or advertised for achieving quite a remarkable or advertising effect.

Abstract: A transparent light-conducting module includes a transparent plate and a sheet light source. The transparent plate has at least one predetermined pattern, which has at least one oblique side. The sheet light source is disposed on at least one lateral side of the transparent plate. The lights emitted by the sheet light source can penetrate through the transparent plate, so that the transparent plate appears bright. The oblique sides of the predetermined pattern can refract the lights from the sheet light source to present a different visual appearance and brightness from the transparent plate around it, thus presenting an extremely aesthetic stereoscopic effect. Therefore, the transparent light-conducting module may be disposed at any location to be marked or advertised for achieving quite a remarkable or advertising effect. Moreover, the elements of the transparent light-conducting module are simple and easy to assemble.
