Integration of LED Lighting Control with Emergency Notification Systems

Abstract

An emergency lighting system for a building includes at least one LED-based light. An emergency detector is operable to detect an emergency. The emergency detector produces an emergency signal in response to the emergency. A controller is operable to control the at least one LED-based light in response to the emergency signal.

1 . (canceled) 
     
     
         2 . An LED-based light, comprising:
 a tubular housing configured to be installable in a standard light fixture;   a plurality of LEDs disposed within the housing;   a controller disposed within the housing;   an emergency detector disposed within the housing; and   a connector arranged at an end of the housing, wherein the connector configured for physical connection to one or more sockets of the standard light fixture such that, when the connector is physically connected to the one or more sockets, the housing, the plurality of LEDs, the controller, and the wireless signal transmitter are secured in the standard light fixture,   wherein the emergency detector is configured to:
 detect an emergency, and 
 responsive to detecting the emergency:
 transmit an emergency signal to the controller, and 
 transmit an alarm notification to an automatic door locking system remote from the LED-based light, 
 
   wherein the controller is operable to:
 absent receipt of the emergency signal from the emergency detector, operate the plurality of LEDs according to a normal mode for general illumination, and 
 responsive to receiving the emergency signal from the emergency detector, operate the plurality of LEDs according to an emergency mode different from the normal mode. 
   
     
     
         3 . The LED-based light of  claim 2 , wherein the emergency is at least one of smoke or a fire. 
     
     
         4 . The LED-based light of  claim 2 , wherein the emergency is at least one of a trespasser or a door ajar. 
     
     
         5 . The LED-based light of  claim 2 , wherein the emergency is weather emergency. 
     
     
         6 . The LED-based light of  claim 5 , wherein the emergency detector comprises a receiver configured to receive an emergency broadcast from a weather service, and
 wherein the emergency detector is configured to detect the emergency based on the emergency broadcast.   
     
     
         7 . The LED-based light of  claim 2 , wherein according to the normal mode, the plurality of LEDs emit white light. 
     
     
         8 . The LED-based light of  claim 7 , wherein according to the emergency mode:
 during a first time span, a first LED of the plurality of LEDs emits light,   during a second time span, a second LED of the plurality of LEDs emits light, and   during a third time span, a third LED of the plurality of LEDs emits light,   wherein the first time span partially overlaps the second time span, and wherein the second time span partially overlaps the third time span, and   wherein the first LED is adjacent of the second LED, and wherein the second LED is adjacent to the third LED.   
     
     
         9 . The LED-based light of  claim 8 , wherein at least one of the light emitted by the first LED, or the light emitted by the second LED, or the light emitted by the third LED is not white. 
     
     
         10 . The LED-based light of  claim 7 , wherein according to the emergency mode:
 during a first time span, a first LED of the plurality of LEDs emits light that increases in intensity from a beginning of the first time span to an end of the first time span,   during a second time span, a second LED of the plurality of LEDs emits light that increases in intensity from a beginning of the second time span to an end of the second time span, and   during a third time span, a third LED of the plurality of LEDs emits light that increases in intensity from a beginning of the third time span to an end of the third time span,   wherein the first time span partially overlaps the second time span, and wherein the second time span partially overlaps the third time span, and   wherein the first LED is adjacent of the second LED, and wherein the second LED is adjacent to the third LED.   
     
     
         11 . The LED-based light of  claim 9 , wherein at least one of the light emitted by the first LED, or the light emitted by the second LED, or the light emitted by the third LED is not white. 
     
     
         12 . The LED-based light of  claim 7 , wherein according to the emergency mode:
 the plurality of LEDs emit light sequentially according to a first line from a first end of the LED-based light to a center of the LED-based light, and   the plurality of LEDs emit light sequentially according to a second line from a second end of the LED-based light to the center of the LED-based light,   
     
     
         13 . The LED-based light of  claim 2 , wherein the emergency detector is configured to, responsive to detecting the emergency, transmit a second alarm notification to an emergency response center remote from the LED-based light,
 wherein second alarm notification comprises an indication of a location of the emergency.   
     
     
         14 . The LED-based light of  claim 13 , wherein the emergency response center is at least one of a fire station or a medical facility. 
     
     
         15 . The LED-based light of  claim 13 , wherein the indication of the location of the emergency comprises an indication of a floor of a building. 
     
     
         16 . The LED-based light of  claim 2 , wherein the LED-based light comprises a wireless transmitter disposed within the housing, and
 wherein the emergency detector is configured to transmit the alarm notification using the wireless transmitter.
