The design of this automatic sprinkler uses Fluid-Driven Illumination technology; when it is activated by fire, the water flows inside the turbine blade to generate electric power instantly and light up the LED, which can act as an illumination device and an alarm during emergency. No battery or utility wires are needed. The second-generation sprinkler is also integrated with a laser projector to highlight evacuation signs and exit locations, increasing the possibility of survival and improving the chance for rescue.
