Abstract
Light and water are typically-important needs in a fire safety and fire-fighting task. However, the traditional designs and studies of relative apparatuses are lack of elements which integrate the interactions of light and water. In this study, the smoke and the water particles which scatter the light are discussed to develop a better design of the illumination in dark fire scenes. In general thinking, battery and utility-wires are the primary options of powering the needed illumination in dark scenes. The old thinking hides the challenges of complexity, high cost, maintenance, insufficient functions, and ergonomics of products. We develop a device that harvests a portion of the hydropower in the water passing through a pipe to drive a micro-turbine alternator and generate electrical power. The water is used to extinguish a fire. The electricity thus generated powers LEDs and laser. Herein, this study provides a synergistic design which takes advantage of the ambient resources sufficiently to supply the demands of the field without extra inputs of energy and people’s efforts. A Nozzle Light provides firefighters with a synergistic function, enabling the user to simultaneously spray water and illuminate the fire scene without requiring additional effort to handle the lighting unit. The Nozzle Light improves both fire-extinguishing efficiency and firefighter safety. And the Sprinkler Light using the scattering effect of laser with particles is integrated with the automatic sprinkler; it is proposed to solve the problem of fire evacuation when there are inadequate or faulty emergency lights or indicators. It is believed that with the development of this study, the possibility of survival and the chance for rescue are increased.
