| 摘要 |
The invention is a new lighting system constituted by a bearing structure (S) that can be inflated manually, with the mouth or electrically with fans, made of fabric or plastic material and provided with one or more light sources (L) at its top and with a support base (B) to its bottom. This bearing structure (S) comprises an airtight air tube provided with a suitable valve system (VG, VS, VR) for the inlet, maintenance and outlet of air and with a manual or automatic system that operates the fans and opens the air inlet valves (VG, VR) to keep a constant pressure inside the structure (S). The pressure can be measured by a set of sensors (PS, PI) connected to a logic circuit that gives or denies consent for the operation of the fans and of the valve. The bearing structure (S) can be produced by combining two surfaces, an inner one suitable for ensuring airtightness and an outer one suitable for ensuring mechanical resistance. The operation of the fans and the valves can be controlled by a timer instead of a logic circuit |
