Optical member for spot flood lights

A luminaire module comprising:

• a substrate;
• a plurality of LEDs mounted on the substrate;
• a one piece molded lens member disposed over the plurality of LEDs, the one piece molded lens member having a generally planar base portion defining an upper surface and a lower surface and a plurality of optical structures arranged in rows and columns on the base portion, each optical structure having a hemispheroidal section extending upwardly from the base portion and a first hemicylindrical section extending upwardly from the lower surface of the base portion and from a side of the hem ispheroidal section, the optical structure having upper surfaces contiguous with the upper surfaces of the base portion, wherein each optical structure is positioned over a corresponding LED to focus light into a desired beam.
