Definitions

  • the present invention refers generally to lighting systems and, more specifically, to a lampshade having an emergency lighting system particularly designed for providing light for a pre-determined period of time after a power failure occurs.
  • an object of the present invention is to provide a lampshade having two completely independent lighting systems, one comprising a conventional lighting device such as an incandescent light bulb powered by an external power source while the other comprises an emergency lighting device such as a low consumption fluorescent light with a few watts power.
  • the present invention refers to a particular type of emergency lighting system for providing light for a pre-determined period of time after a power failure has occurred, more specifically, to such a device particularly designed to be housed inside any regular lampshade housing, thereby solving the above discussed problems of design, practicality, bulkiness and cost.
  • the design and constructive features of the emergency lighting system may vary from one specific embodiment to another, so that it will be able to be housed inside the housing of the lampshade, basically it comprises a lampshade having an emergency lighting system, comprising:
  • the first lighting device preferably a conventional incandescent lamp, operates normally according to the on/off position of said switch, while said battery recharger is also being supplied with power to maintain rechargeable battery with a minimum level of charge.
  • the automatic switch is automatically started to switch on said battery, turning on said second, emergency lighting device with the charge from said rechargeable battery. This condition is maintained until the power failure situation is reverted.
  • the lampshade according to the present invention is suitable for use in several different environments - domestic, commercial or industrial.
  • An important example where it can be used is in children's rooms or in rooms where old people or sick people live, where it is important that the room be constantly illuminated.
  • the emergency lighting system according to the present invention can keep such an environment duly illuminated for a considerable period of time should a power failure occur.
  • a lampshade having an emergency lighting system is shown as comprising a conventional lampshade 1 having a base portion 2, a framing structure 3 projecting upwardly from said base portion 2 and a shade portion 4 supported by said framing structure 3.
  • a power wiring or cable 6 having a plug 7 in one end for connecting with an external power source (not shown) and an on/off switch (CH) provided thereon runs through said base portion 2 to supply power to a first lighting device 5 such as a conventional AC, 110/220 volts, incandescent light bulb.
  • a second, emergency lighting device 8 such as a low consumption fluorescent light is positioned inside said shade portion 4, hanging from or supported by said framing structure 3.
  • a rechargeable battery 9 for supplying power to said second, emergency lighting device 8 whenever a power failure occurs is also positioned within said lampshade 1, with an electronic circuit 10 connecting said rechargeable battery 9 to said external power source.
  • the electronic circuit 10 comprises a monitoring circuit 12 for detecting a power failure of said external power source, an automatic switch 13 responsive to said monitoring circuit 12 for automatically connecting said second, emergency lighting device 8 to said rechargeable battery 9 when a power failure is detected, and a battery recharger 11 to maintain said rechargeable battery with a minimum level of charge.
  • Said monitoring circuit 12, automatic switch 13 and battery recharger 11 are interconnected in such a way on said electronic circuit 10 that the power being fed through said power wiring 6 can be simultaneously supplied to light said first lighting device 5 when said on/off switch CH is on and to said battery recharger 11 to charge said rechargeable battery 9.
  • Said electronic circuit 10 additionally includes a on/off push-button 14 for testing the second, emergency lighting device 8.
  • the monitoring circuit 12 on the electronic circuit 10 detects a power failure from the external power source, such as a lack of electric current in the power wiring 6, this detection is immediately passed on as an output to the automatic switch 13, which automatically connects said second, emergency lighting device 8 to said rechargeable battery 9, therefore turning it on.
  • the automatic switch 13 When the power failure is over, the automatic switch 13 returns to its normal operational position, turning off said second, emergency lighting device 8 and restoring the operational capability of the first lighting device 5.
  • the configuration of the electronic circuit provides for the recharging circuit 11 to start recharging the rechargeable battery 9, to bring it back to a normal level of charge.
  • the assembly defined by the circuit 10 and rechargeable battery 9 having the above configuration can be assembled or positioned within the base 2, with only the testing switch 14 being exposed, as illustrated in Figure 1.
  • the power passing through the wire 6 also keeps the battery 9 duly charged and it is automatically activated when there is a power failure, independently of the condition on or off of the first lighting device 5.
  • the user is provided with the benefit of a suitable emergency lighting system illumination which, besides starting operating automatically, does not require any manual handling. Also, a system that is also automatically switched off when the power failure is over. Another automatic feature is the maintenance of the battery charge because while the regular electric current is being fed said battery is kept with its full charge, and said charge is enough for keeping the emergency lighting system light activated for a very long period of time when a power failure occurs.
