Patent ID: 8836532

Claim:
A notification appliance configured to emit a notification output based upon at least one detected environmental condition comprising: a sensor configured to detect the at least one environmental condition; at least one light emitting diode (LED) light source configured to emit light having an intensity during a pulse time period, wherein said emitted light corresponds to said notification output; an ambient light sensor configured to detect ambient light in an area proximate said notification appliance; and a controller in communicative connection with said sensor, said at least one LED light source, and said ambient light sensor, wherein upon detection of said at least one environmental condition, said controller is configured to alter said intensity and said pulse time period of said emitted light as a function of said detected ambient light, wherein said controller alters said intensity and said pulse time period of said emitted light as a percentage of one another, and said pulse time period is approximately less than or equal to two hundred milliseconds (200 ms), so as to substantially maintain an effective intensity and enhance a perceived brightness of said emitted light.
