Abstract

PURPOSE: To economize electric power and miniaturize an entrance illuminator, by attaching a supersonic moving body detector to a porch lamp.
CONSTITUTION: A horn case 3 and a supersonic horn 4 are mounted together on a rotary plate 5 and a metal rod 7 under the porch lamp 1 and are then attached to a wall W through a mount 9 containing a metal pipe 8 and an supersonic moving body detection circuit 10. When a person comes into a supersonic detection zone, an illuminating lamp 2 is lighted on through the supersonic moving body detection circuit 10 for a set time. As a result, electric power is economized, crimes are prevented and the entrance illuminator is miniaturized and easy to install
