Definitions

• Monitoring devices are already known which are supplied by the electrical network. These devices can be sensitive to various phenomena such as for example the presence of smoke or an abnormal rise in temperature, this in the case of fire detectors. These devices can also include a sensor sensitive to infrared rays, for example to detect the presence of an intruder in a room to be monitored.
• connection cable to connect the detector to the network and in addition it was necessary to provide means for fixing the detector, for example to a wall of a room to be monitored.
• the present invention aims to eliminate these installation works. To this end, it relates to a device for monitoring a place provided with an electrical lighting installation, this installation comprising means for connecting an illuminating element to the electrical supply network, this device comprising a sensor sensitive to a phenomenon to be monitored, characterized in that this arrangement comprises a housing provided with contacts similar to those of the lighting element, so as to be able to be connected to the network by replacing it with said lighting element.
• FIGS. 1 and 2 of the accompanying drawing show schematically and by way of example two embodiments of the dispositi f subject of the invention.
• Figure 1 shows the first embodiment in which the dispositi f comprises a housing 1 provided with a screw base 2 for placing it in a doui the intended to receive a light bulb.
• This device comprises a sensor housed in the housing I and a returned transmitter active by this sensor, this transmitter being able to be of the kind described in the Swiss patent N ° 642.208.
• the housing 1 also comprises a control lamp 3, for example a light diode, which indicates whether the monitoring device is correctly connected to the network.
• the signal sent is received at another point on the network by a receiving device provided for this purpose. It is clear that the transmitter could be provided for the transmission of radio waves which could be picked up by any radio receiver provided for this purpose, or even that the transmitter could simply produce an acoustic or optical alarm signal.
• This indicator light is very useful because the lighting lamps are generally connected to the network by a switch and it is obvious that if the interrupter is open, the monitoring device cannot function. This indicator light therefore allows the user to verify that the switch has not been inadvertently opened.
• FIG. 2 shows an embodiment in which the housing • of the monitoring device has substantially the shape of a fluorescent cent lighting tube and can therefore be substituted for such a tube.
• This device presents at each end of the housing two pins 5 corresponding to the contact fingers with which the usual lighting tubes are provided.
• This tube has a detector 6 which is mounted to rotate on the housing, so as to allow it to be oriented in the desired direction, whatever the position of the pins 5 when the device is mounted on a base for luminescent tube.
• the device according to the invention is very advantageous, because not only does it avoid all installation work, but also the lighting elements are most often located above an area to be monitored, ie at ceiling of a room, either against a wall or on a pole when lighting an outdoor place.
• the locations where such monitoring devices can be fixed are favorable to allow effective monitoring. It is also possible to fix the monitoring device in a mobile lamp, for example a bedside or work lamp.
• the device has the advantage of being powered by the network, which avoids many problems related to battery power.
