Motion sensing lighting fixture

A motion sensing lighting fixture comprising:

• a support post;
• a sensor-containing support device mounted on said support post, said sensor-containing support device having a housing covered by an enclosure;
• at least one window in the housing that allows infrared radiation to pass through to the interior of the housing;
• and
• a passive infrared motion sensor mounted in the interior of the housing and adapted to sense infrared radiation passed through the window over a greater than 180-degree field of view, wherein the passive infrared motion sensor is mounted so as to face downward.

A post top motion light having a wide area field of view comprising:

• a lamp in electrical connection to a control and power supply circuit;
• a motion sensor housing below said lamp;
• a motion sensor suspended within said motion sensor housing and having a downward field of view;
• a reflector mounted in said motion sensor housing and below said suspended motion sensor;
• wherein said reflector is surrounded by a lens and collimates radiation through said lens and upwards toward said motion sensor.

A motion sensing lighting fixture comprising:

• a support post;
• a light mounted on the support post;
• and
• a passive infrared motion sensor fixedly contained in said support post and adapted to sense infrared radiation.
