Abstract

A light fixture has motion detection circuitry enclosed within a motion detector housing. The motion detector housing contains at least one thermal detector such as a passive infrared sensor, the sensor having a detection angle. At least one adjustable blind is housed within the housing adjacent to the infrared sensor, and the blind is adjustable to block and limit the detection angle of the sensor. The blind may be directly connected to a knob on a control panel that allows the user to alter the angle of the blind. Two or more blinds may be used on the interior of the housing, to increase adjustability of the detection angle.
