Nozzle Light Powered by Energy Harvesting Technology

The invention of this study harvests a portion of hydropower in the fire hose to drive a micro turbine generator and the electric power generated is used to light the LED （light-emitting diode） attached on the fire nozzle for the illumination of dark scene （it is called nozzle light in this study）. The simulation and experiment are done to match the design of nozzle light. Nozzle light provides firefighters a synergistic function to spray the water and illuminate the fire field at the same time without requiring any extra hand to handle the light. It indeed increases both the efficiency of putting off a fire and the safety of firefighters. The most innovative benefit is that neither heavy battery nor utility wires are needed to get the lighting.
