ABSTRACT:
A motion sensor assembly has a housing with an opening therein, an infrared detector, a lens which may be of the Fresnel type, a holder, a circuit, and a transformerless direct current power supply that provides power to the circuit and detector. The housing has an interior space bounded by at least one wall. The opening is formed in the wall. The holder receives and secures both the lens and the detector so that the lens focuses a field of view on the detector. The holder also orients the detector and lens so as to reduce internal reflections between the lens and detector. The holder further mounts both the lens and the detector adjacent the opening in the wall. A radiation permeable covering disposed in the opening conceals the elements of the assembly within the interior space of the housing. In one embodiment, the radiation permeable covering includes louvers. When a source of infrared radiation moves across the field of view, the detector outputs a signal responsive to infrared energy radiated from the source. The circuit provides a signal in response to the output signal of the detector. A lamp may be driven by the signal of the circuit.
