(57) A miniaturised and sealed PIR sensor device adapted to be positioned within the body
of a lighting appliance and comprising a housing (10) with integrally moulded lens
(12) and containing a PIR sensor (14) behind the lens (12) and associated switching
circuitry (15) contained within the housing (10). A sealing substance (16) fills the
remaining space of the housing (10) beneath a welded-on back plate (11). The device
may be located conveniently behind the mounting plate of a wall mounted lighting appliance
with the lens (12) exposed by or projecting through a small aperture in the appliance.
The device obviates the need for a separate PIR housing alongside of beneath the appliance.
