Solar powered interior lighting - has flexible transparent glass conductor with convergent and divergent optical lenses at ends

摘要

The cold lighting uses solar light transmitted through a conductor of transparent glass fibres (1). It has two optical systems, convergent (4) and divergent (8) at its ends (7 and 3). The light conductor is made up of continuous transparent glass threads (2). These threads are strands or flexible cord. The conductor is flexible and can be adapted to all forms of circuit and installation. No heat is transmitted through the conductor. This not only saves energy, but avoids problems with ventilation to remove heat.
