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 heat sink for a luminaire includes a central portion having a top surface and a bottom surface. The bottom surface is adapted to receive a lighting arrangement. The heat sink further includes a plurality of arms configured to dissipate heat generated by the lighting arrangement. The plurality of arms extend radially outward from the central portion. Each one of the plurality of arms is substantially arcuate between a proximal end and a distal end.
