Abstract
Apparatus providing beamforming and environmental protection for LED light sources. A lens apparatus is provided to protect an LED mounted on a substrate. The lens apparatus includes an alignment feature configured to align the LED to a selected position and a focusing region configured to form a selected beam pattern from light emitted from the LED when located at the selected position. The lens apparatus also includes a compression surface configured to compress the substrate to a heat sink to facilitate heat dissipation from the LED and a fastening feature configured to fasten the lens apparatus to the heat sink to provide an environmentally protective seal, so that when the lens apparatus is fastened to the heat sink the alignment feature aligns the LED to the selected position, the compression surface compresses the substrate to the heat sink, and the protective seal protects the LED from environmental conditions.
