Abstract

Today optical fibre and sunlight receiver technology allows bringing sunlight inside a building through optical fibre. The principle is the following: a solar concentrator receives the sunlight and brings it to a bulb inside the building through optical fibre. This article relates on the application of this technology to an aircraft cabin. The concentrator could be placed between the panes of aircraft windows or on the fuselage. A switch could be provided to provide artificial light, hybrid light (artificial combined with natural) or natural light depending on the need in the cabin.

Solar light reoriented inside plane using optical fibre

Abstract:

Today optical fibre and sunlight receiver technology allows bringing sunlight inside a building through optical fibre. The principle is the following: a solar concentrator receives the sunlight and brings it to a bulb inside the building through optical fibre. This article relates on the application of this technology to an aircraft cabin. The concentrator could be placed between the panes of aircraft windows or on the fuselage. A switch could be provided to provide artificial light, hybrid light (artificial combined with natural) or natural light depending on the need in the cabin.

Context:

A window can be made with two panes (inner and outer) maintained together with a pressure seal. It must be interchangeable.

Such windows permit to:

    - define a clear area to have a clear view;
- prevent air / water leakage and noise from the cabin, even under negative cabin pressure;

    - provide a "fail-safe" system that means that the inner pane can hold the cabin pressure in a case of damage on the outer pane.
.

New application:

The architecture proposed aims at reducing the consumption of energy and providing a customer experience. The solution is a solar concentrator which receives the sunlight and with an optical fiber brings this sunlight into a bulb inside an aircraft.
