PORTABLE LIGHT PROJECT - Portable Storefront Prototype


PORTABLE STOREFRONT prototype Sheila Kennedy, Principal Investigator Saarinen Professor University of Michigan Frano Violich, Saarinen Professor, University of Michigan Keith VanDerSys, Lecturer, University of Michigan Mark Davis, University of Michigan Joseph Kim, University of Michigan Loukas Kozonis, University of Michigan The PORTABLE STOREFRONT prototype integrates photovoltaic energy harvesting capabilities with solid state lighting in a wearable textile poncho that unfolds to provide an illuminated market space for Huichols to sell their craftwork when they travel. The Portable Storefront provides two and one half hours of digital light at 160 lumens with approximately fours hours of charge time. The design of the Portable Storefront protects user and his/her goods from the elements and provides solid state lighting for travel as well as storefront visibility in dark areas. HBLEDs are integrated into the arm cuffs and hood to provide directional illumination for walking. When suspended as a storefront, the transparent pouches on the back allow specific goods to be visible yet protected for purchase. Sun light is collected with flexible solar panels located on the back of the poncho and is stored within two lightweight lithium batteries contained in a central pouch with other electrical components.
