PURPOSE: An LED(Light Emitting Diode) lighting device is provided to scatter light which is discharged from a LED device by injecting scattered gas into a cylinder member. CONSTITUTION: A cylinder member(10) is made of a transparent or an opaque material. The cylinder member has a circular or a polygonal cross-section. Scattered gas is inserted into the cylinder member. The scattered gas is inert gas such as argon and xenon. A pair of cap members(20) are combined with both ends of the cylinder member. An LED module comprises at least one LED elements(23) and a LED substrate(22). The sealing member is arranged in the contact part between the cap member and the cylinder member in order to prevent the leakage of the scattered gas. |
