Abstract
A roadway luminaire is provided which includes a mast mount docking sation securable to an end of a pole mast. The mast mount docking station includes a power plug electrically coupled to the power conductors. The luminaire includes a corresponding power plug which is electrically and mechanically coupled to the mast mount docking station via a twist-lock feature including mating keys and keyways in the docking station and luminaire, respectively. The luminaire includes several plug-in components such as a plug-in photoelectric cell, a plug-in starter and a capacitor pressfit into a molded cavity in the luminaire. The power plug of the luminaire is adaptable to be used with all international voltages. The twist-lock feature provides for a foolproof mechanical and electrical connection to ensure that the correctly rated luminaire is connected to the supply voltage.
