Abstract
In an embodiment, there is provided a three-dimensional (3-D) optic for beam shaping. The 3-D optic includes a first surface, a second surface and a beam forming feature. The first surface is configured to receive incident light. The second surface is positioned relative to the first surface and is configured to emit a light beam having a shape. The emitted beam shape is related to the beam forming feature. The beam forming feature is formed by a 3-D manufacturing process.

A three-dimensional (3-D) optic for beam shaping, the 3-D optic comprising:
- a first surface configured to receive incident light;
- a second surface positioned relative to the first surface, the second surface configured to emit a light beam, the emitted light beam having a shape;
- and
- a beam forming feature, the emitted beam shape related to the beam forming feature, the beam forming feature formed by a 3-D manufacturing process, wherein a dimension of the beam forming feature is at least twice a maximum wavelength of the incident light.
A lighting fixture comprising:
- a light source assembly comprising at least one light source, each light source configured to emit incident light;
- and
- a three-dimensional (3-D) optic configured to receive the emitted incident light and to emit a light beam having a beam shape, the 3-D optic comprising:
- a first surface configured to receive the incident light;
- a second surface positioned relative to the first surface, the second surface configured to emit the light beam, and
- a beam forming feature, the emitted beam shape related to the beam forming feature, the beam forming feature formed by a 3-D manufacturing process, wherein a dimension of the beam forming feature is at least twice a maximum wavelength of the incident light.
