Definitions

  • the invention relates to the field of emergency lighting devices, such as emergency lighting devices using LEDs.
  • the power failures may be caused by electrical short circuits, brownouts, fire, accidents, natural disasters (i.e., floods, hurricanes, tornadoes, etc.), or a planned shutoff of electricity to a facility or dwelling.
  • emergency lighting devices with rechargeable central or decentral batteries are designed for use with LED emergency lighting means and can be operated as part of a combined system with electronic LED drivers.
  • emergency devices for lighting means such as LEDs
  • EP 1 885 039 A2 and WO 2012/089335 A1 disclose an emergency device for lighting means according to the preamble of independent claim 1, respectively.

  • each emergency device in the office or room can preferably contain the data for all other emergency devices in the area/room/office.
  • the inter-device communication according to the invention is not limited to one adjacent device. It can be extended to 1-n devices only limited by memory and proximity, n being the total number of devices.
  • Using a device-to-device wireless communication has the advantage of improving the reliability and performance of an emergency system.
  • a wireless communication is used in order to enable devices to communicate with a base station for controlling and reporting.
  • the emergency device-to-emergency device communication is facilitated in order to improve system performance and reliability.
  • the emergency devices can instigate the exchange of information between each other in order to facilitate their communication.

  • failures in the device-to-device communication are often identified by loss of communication with an emergency device (no answer to a query), although this could also be related to the connection infrastructure.
  • An important feature of a wireless emergency system employing a mesh network is that a communication path is available and several local devices can hold data about neighboring devices. This provides the advantage that, by local device-to-device communication, it is possible to identify when an emergency device was broken because several local devices would be sharing data.
  • the emergency device for lighting means is configured to store in a memory configuration data of at least one neighboring emergency device.
  • this has the advantage that a replacement support by storage of neighboring emergency device configurations can be done, so that, when an emergency device is detected as failed, a new emergency device can be programed from the neighboring emergency devices.

  • the emergency device 1 typically monitors the states of an alternating current AC and is connected to emergency lighting means 2. Moreover, the emergency device 1 may be connected to the external DC supply 4'.
  • the emergency device 1 is one or more light-emitting diodes (LEDs).
  • LEDs light-emitting diodes
  • LEDs require specialized devices called LED drivers 5 to operate.
  • LED drivers 5 also known as LED power supplies
  • LED power supplies are similar to ballasts for fluorescent lamps or transformers for low-voltage bulbs: they provide LEDs with the electricity they require to function and perform at their best.
  • LED drivers 5 also protect LEDs from voltage or current fluctuations. A change in voltage could cause a change in the current being supplied to the LEDs. LED light output is proportional to its current supply, and LEDs are rated to operate within a certain current range (measured in amps). Therefore, too much or too little current can cause light output to vary or degrade faster due to higher temperatures within the LED.
  • the LED driver 5 supplies, in a controlled manner, the lighting means 2 with electrical power.
  • the detection unit 8 is configured to detect if there is an alternating current supply and, in case of an AC power supply failure, the emergency device 1 is driven by a DC power supply from the internal DC supply 4 or the external DC supply 4' in order to operate the lighting means 2 in such an emergency condition.
