[0001] The present invention relates to a self-contained apparatus for emergency lighting
comprising at least one sensor/detector sending an electric input to a processor,
and A detection and alarm system controlled by upsaid processor.
[0002] It is known that, in case of current cutoff and/or gas escape or fire, a timely alarm
signal is required to allow prompt aid intervention and/or danger neutralization.
[0003] In the state of art, several other systems for the detection of such events are known;
however, they show some determinant limitations: among them, the need to be constantly
connected to a supply mains and, in case of portable lamps, the impossibility to incorporate
gas detectors or the like.
[0004] Therefore, the technical problem is to produce a self-contained lighting apparatus
suitable for the detection and alarm signalling of other casual dangerous events such
as gas escapes, fires and the like, which can arise in the border area of the lighting
apparatus position.
[0005] These aims are all achieved by the self-contained apparatus for emergency lighting
object of the present invention, which comprises lighting means, detection means for
gas, smokes, heat and the like, which send the electric input, processing means which
receive upsaid electric input, and alarm means which can be activated by upsaid processing
means, so that dangerous events can be detected and signalled in real time and without
any need of supply mains.
[0006] Further characteristics of the present invention will be better disclosed from the
following detailed description of an embodiment of the invention, with reference to
the drawings, where the following items are:
- in fig. 1, an apparatus according to the present invention, showing a lateral view
of a portable lamp;
- in fig. 2, the front view of the portable lamp shown in fig. 1. From the abovementioned
figures it can be noticed that in body 1, provided with a handle, transparent screen
2 is inserted in the forepart; lighting element 3, supported by its caps, is positioned
under the screen.
[0007] On the handle, switch 4 can be changed over in three positions: with plug 9 connected
to the supply mains; on position II, only gas detector 5, corresponding to louvers
6 and 6′, is on; on position I also the emergency lamp, in case of current cutoff,
gets on. When plug 9 is disconnected from the supply (self-contained portable lamp),
with the switch on "O" position, the system is completely off; on "I" position, both
gas detector and emergency lamp are on; on "II" position only the gas detector is
activated.
[0008] In a danger situation due to gas emission, the alarm consists in LED 7 blinking and
in the intermittent acustic signal from louvers 8-8′.
[0009] After a predetermined time, lamp 3 flashes as well, while the acustic signal continues.
[0010] In practice, many constructive modifications of the present invention can be introduced,
especially as for the details of the circuit, already known in itself and then not
further described, and as for the detector and processor configuration.
[0011] Particularly, the detector utilized in the apparatus object of the present invention
can be sensitive to the gas resulting from the combustion of either organic or inorganic
substances (for instance, an oxygen detector set at the oxygen concentration value
indicating a progressing combustion); or else, it can be a temperature sensor (for
instance, an infrared ray absorption detector); again, it can be a threshold P.E.C.,
detecting the sudden bright light resulting from a fire.
[0012] A first embodiment of the apparatus of the present invention is provided with a detector
of the abovementioned type, incorporated in an emergency lamp and connected to a processor
which processes the signals sent from upsaid detector, where a first input detects
fire absence and a second one detects fire presence; upsaid processor sends a first
output to the alarm system disabling it to function, when the processor receives upsaid
first input, and a second output enabling it to function, when the processor receives
upsaid second input.
[0013] In another embodiment of the invention, the apparatus is provided with a sensor of
the abovementioned type, incorporated in an emergency lamp and connected to a processor
for the processing of the signals coming from upsaid sensor; the processor operates
as already described hereabove; it is connected only to one sensor; this apparatus
is provided with the same number of processors and sensors, being these processors
connected to upsaid sensors.
[0014] In another embodiment, upsaid connection is obtained through electric wires.
[0015] In another embodiment, upsaid connection is made by means of electromagnetic waves,
so that upsaid processors are provided with a sender and encoder, and the abovementioned
alarm system is provided with a receiver and decoder. Finally, of course, the apparatus
can be provided with two or more of the abovementioned detectors at the same time,
all incorporated in the same emergency lamp.
1) SELF-CONTAINED APPARATUS FOR EMERGENCY LIGHTING provided with rechargeable battery,
characterized in that it comprises lighting means, detecting means for gas, smokes,
heat and the like, which can send an electric input, processing means receiving upsaid
electric input, and alarm systems activated by upsaid processing means, so that dangerous
events can be detected and signalled in real time and without any need of electric
supply.
2) APPARATUS as claimed in Claim 1, wherein upsaid alarm systems are optic and/or acustic.
3) APPARATUS as claimed in Claim 2, wherein upsaid apparatus is provided with a same

is obtained by using the main light source of the emergency lamp (fluorescent or incandescent
lamp).
7) APPARATUS as claimed in Claim 1, wherein the incorporated processor activates a fixed
acustic and optic alarm system, preventing the fixed optic alarm system (lamp) to

optic and acustic alarm system are operated by incorporated rechargeable batteries,
autonomously from the electric supply.
