AUTOMATICALLY CONTROLLED LIGHTING DEVICE, AND AN INSTALLATION INCLUDING A PLURALITY OF SUCH DEVICES
First Claim
1. A lighting device (10;
-
42) comprising;
a radio receiver circuit (24);
search means (20) co-operating with the radio receiver circuit to detect and identify neighboring objects (34, 36, 38, 40) present in the proximity of the device, these neighboring objects being themselves provided with radio transmitter circuits suitable for interfacing with said radio receiver circuits; and
control means suitable for causing a light source (12) to switch off;
the device being characterized in that the control means;
co-operate with the search means (20) to;
detect the appearance or the disappearance of said neighboring objects in the radio range of the lighting device; and
cause the light source to switch off on detecting the disappearance of at least one neighboring object, conditionally as a function of predetermined switch-off criteria; and
operate essentially without a switch-off order being transmitted from the neighboring objects to the device.

Abstract
The lighting device (10; 42) includes means for switching a light source on and/or off and search means suitable for detecting and identifying neighboring objects (34, 36, 38, 40) present in the proximity of the device and provided with radio transmitter circuits, e.g. of the Bluetooth type, that are suitable for interfacing with the device. The device includes means for causing it to switch off, and possibly to switch on, said means co-operating with the search means (20) to detect the appearance or the disappearance of neighboring objects in the radio range of the lighting device, and to trigger switching off of the light source on detecting the disappearance of at least one neighboring object, conditionally as a function of predetermined criteria. Switching is controlled essentially without orders being transmitted from neighboring objects to cause the lamp to switch off or on. A plurality of devices of the same type may be configured with one another and with the neighboring objects they have detected, in a hierarchical network topology.
