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.

A LED luminaire comprising:
- a body portion having at least one lighting module therein;
- and
- an optical structure formed within the body portion and located in a light-projection direction of the lighting module, the optical structure substantially being a sheet-like structure with a first surface and a second surface;
- wherein the first surface has at least two side portions with a first curvature, the second surface has a second curvature, and the first curvature is greater than the second curvature so that the optical structure is provided for increasing view angle of light generated from the lighting module;
- wherein a circular center defined by the second surface and a core center of the body portion are coaxial.
A LED luminaire, comprising:
- a body portion having at least one lighting module therein;
- and
- an optical structure formed within the body portion and located in a light-projection direction of the lighting module, the optical structure substantially being a sheet-like structure with a first surface and a second surface, and the first surface and the second surface being not parallel to each other;
- wherein the first surface is farther from the lighting module than the second surface, the curvature of the first surface is greater than the curvature of the second surface so that the optical structure is provided for increasing view angle of light generated from the lighting module;
- wherein a circular center defined by the second surface and a core center of the body portion are coaxial.
