Abstract: A portable lighting system is disclosed. The portable lighting system includes at least one light-emitting source, a power-generating source, a power storage device, and a processing system for controlling and managing power-generated by the power-generating source that are all are integrated into a flexible-layered structure. The flexible-layered structure is a layered structure of woven or non-woven, natural or made-made fibers that have been joined using sewing, sonic-welding or heat lamination manufacturing techniques. Materials for the flexible-layered structure include woven textiles, non-woven materials, flexible plastics, natural leather materials, artificial leather materials, reflective flexible materials, opaque flexible materials, translucent flexible materials, light-diffusing materials, and specular reflective materials.

Abstract: A ceiling tile system comprises modular acoustic light-emitting modules which can be of a standard size to be fitted into a hung ceiling or other ceiling system in conjunction with similar acoustic light-emitting modules or conventional ceiling tiles. Each acoustic light-emitting module includes a backing panel, a cover, and a rigid spacing member extending between the backing panel and the cover, with solid state light-emitting elements such as light-emitting diodes (LEDs) arrayed within each module. The cover may be made of fabric including metallic threads to enhance the diffusion of light. In one embodiment, two arrays of LEDs are provided on respective modules. The arrays may be driven independently or together. The LEDs provide shades of white light or colored light, as desired. The cover and lighting elements may be readily removable from the backing panel for ease of maintenance.
