<p>Sunbrellas, roof tents, architectural membranes, sails, textile buildings, and shades generally, with reflective and/or luminescent features, solve the problem of solely using electrical or other power for lighting of shield areas and architectural structures by creating them as a landmark in the environment at night by using reflective-luminescent or luminescent material or their combinations on the visible parts of the devices and structures, which can reduce or eliminate power needs for their illumination, also giving them sufficient LLL in case of emergency.</p> |
