Abstract

A LED luminaire includes a body portion having a lighting module and an optical structure formed integrally with the body portion. The optical structure is formed within the body portion and located in a light-projection direction of the lighting module. The optical structure substantially is a sheet-like structure with a first surface and a second surface. The first surface has at least two side portions with a first curvature, and the second surface has a second curvature. The first curvature is greater than the second curvature. Thereby, the view angle of the light is increased as the light generated from the lighting module passes through the optical structure.
