US Patent 7963681 Race track lighting fixture and race track lighting system

A race track lighting system comprising a plurality of fixtures mounted in spaced relationship to one another on the infield side of the track and projecting light outwardly and downwardly onto the track surface from relatively low poles. Each fixture is asymmetric so as to provide a strong cut-off preventing light from being projected into the eyes of oncoming driver, but a divergent pattern in the direction of traffic flow so as to blend the light from one fixture with the light from an adjacent fixture for the purpose of promoting uniformity in the lighting intensity. The lamp is offset in the fixture and a blocker strip is placed in from of the lamp to prevent direct, uncontrolled light from reaching the track.
