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.

Apparatus providing beamforming and environmental protection for LED light sources

A street light includes a pole and a head attached to the pole. The head includes a light emitting element comprising a plurality of solid state light emitting devices, an optical element, and a reflector configured to reflect light emitted by the solid state light emitting devices to the optical element to produce a light distribution pattern from the head. The light emitted from the solid state emitting devices may be Lambertian patterned light. The Lambertian patterned light may be used to illuminate the reflector. The reflector may be used to transform the Lambertian patterned light to collimated light and direct the collimated light towards the optical element. The optical element may be configured to produce the light distribution pattern from the collimated light.

One embodiment of the current invention seeks to increase heat dissipation in solid state lights used in track lighting systems, by utilizing a track with a fluid channel. Convective heat transfer within this fluid channel acts to dissipate more heat than can be typically dissipated by conventional solid state lights themselves, thus allowing for brighter, higher-powered lights. The track and fluid channel can take on various forms.

Fluid pipe heat sink apparatus for solid state lights

Embodiments of the current invention seek to increase heat dissipation by affixing a separate or integrated heat sink to the solid state light, thus accomplishing increased heat dissipation via another device, instead of altering the solid state light itself. In this manner, embodiments of the invention increase the amount of heat dissipated from solid state lights without requiring any redesign of the solid state lights themselves.
