Surface wind. Surface wind is the wind blowing near the Earth's surface. It is measured by an anemometer (speed) or wind vane (wind direction) at a standard height of 10 m above ground in an area where the distance between the instrument and any obstruction is at least 10 times the height of the obstruction.
Outdoor luminaire using light emitting diodes
InactiveUS20090213588A1Improve cooling effectPlanar light sourcesMechanical apparatusLuminosityModularity
A luminaire that uses Light Emitting Diodes as a light source, and which is intended to be securely mounted outdoors on a pole or arm of widely varying diameter. The luminaire is modular, in the sense that a major component may be removed, repaired and / or replaced for maintenance or for upgrade purposes, without tools, and without modification to any other component in the luminaire. The luminaire's main component is a light engine comprised of Light Emitting Diodes mounted to a thermally conductive circuit board, which in turn is mounted to a thermally dissipative heat sink which resides on the outside of the luminaire. The thermally dissipative heat sink is specifically constructed to take full advantage of horizontal surface winds at the recommended mounting height of the luminaire, to aid in the dissipation of heat created by the Light Emitting Diodes and power components. The Light Engine is mounted in a housing facing downward, with respect to light output, directly over an aperture, or hole in the lower housing, whereby one of several different lenses may be placed to provide a desired photometric output. This structure and method of manufacture allows for use of almost any LED technology that exists, as well as those in the emergent and conceptual stages.
