Abstract
A light-emitting diode (“LED”) based strobe may be used in automated system to provide a visual alert to occupants and/or building personnel if an emergency condition exists. A LED based strobe provides an even distribution of light having a sharp, bright pulse of light desired for emergency evacuation using lower power consumption.
