(54) Improvements in pole operation of luminaires


(57) A pole operator and method of use thereof for adjustment of a luminaire, comprising a pole (10) having a magnetic cone drive end fitting (22) which is engageable with a complementary cone-shaped fitting on the luminaire. The cone drive fitting (22) is rotationally mounted on a tilting pole head (12). The magnetic fitting is switched on as the pole head is approached to the luminaire, thereby to become substantially self engaging to the luminaire fitting, and is switched off before disengagement after the luminaire has been adjusted, thereby enabling its detachment without disturbance of the adjusted luminaire.
