Recently, a new type of textile-based lighting material has emerged that absorbs solar energy during the day and provides illumination for millions of people living in places without electricity facilities at night. Six such portable illuminating samples correspond to the brightness of a 60 watt bulb. A 14-ounce shoulder strap transforms into a lighting canopy; a 2.5-pound shoulder bag opens as a lantern; a 3-pound backpack can also be used as a lighting tool. An 8 ounce pad can be rolled up or opened to provide ample reading space. This portable light source model can be made into portable bags, even tools, mats and shoulder straps, to provide lighting for homes, classrooms and small village factories, as well as to improve the living community of the developing community. situation. The project's main researcher, Hira Kennedy, said: "The infrastructure of this portable light source is dispersible and does not need to be connected to any power source." The University of Michigan scientists developed the luminescent fabric using the following technologies: Solar cells woven into the fabric absorb solar energy and convert it into a voltage. The lithium battery is charged by such a voltage, and the resulting electric energy supplies energy to the light-emitting diode woven into the cloth. The textile used to make the luminescent fabric is made of translucent, anti-reflective fabric that is extremely durable and enhances the brightness of the light. Each charge of 5 hours is enough to provide 5 hours of illumination for reading and working. Currently, Kennedy is trying to turn this sample into a commercial model with a small return, making semiconductor manufacturers interested in turning this portable light source into a portable product. Enable members of the community to use it for a small amount of money when needed. (Kexin)
