Abstract: A wide-angle linear LED lighting device includes a polygonal lampshade, a base and at least two LED modules. The polygonal lampshade includes at least two lateral parts and an installation part. The base is disposed within the polygonal lampshade and disposed on an inner surface of the installation part. There is an included angle between the base and the inner surface of the installation part. The at least two LED modules are disposed on the base. The light beams emitted by the at least two LED modules are outputted from different lateral parts of the polygonal lampshade. The light-outputting characteristics of the wide-angle linear LED lighting device are correlated with the included angle and the at least two LED modules.
