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.

A wide-angle linear LED lighting device, comprising:
- a polygonal lampshade comprising at least two lateral parts and an installation part;
- a base disposed within the polygonal lampshade and disposed on an inner surface of the installation part, wherein there is an included angle between the base and the inner surface of the installation part;
- and
- at least two LED modules disposed on the base, wherein light beams emitted by the at least two LED modules are outputted from different lateral parts,
- wherein the polygonal lampshade has a linear hollow tube profile with a hollow trapezoid cross section, and a front part of the polygonal lampshade is longer than the installation part, by adjusting the included angle and the position of the at least two LED modules incorporating with the inverted trapezoid profile of the polygonal lampshade, light-outputting characteristics are adjusted and the backside energy and the spatial background brightness are increased.
