the present invention is a lighting system for providing illumination to an aircraft evacuation slide . light sources are safely utilized with an existing evacuation slide , a substantial improvement over prior assemblies that use a hard , plastic housing enclosing the light source . the invention increases light transmission , eliminates housing cracking , inadvertent puncturing , clouding , and decreases weight and cost of conventional slide systems . each assembly comprises a mounting surface and a printed circuit board thereon , light sources , preferably light - emitting diodes mounted on the mounting surface , the light sources illuminating the aircraft evacuation slide , and a flexible containment covering , such as a heat shrink wrap that covers the assembly and protects the light sources . a protective shield can cover the mounting surface while allowing the leds to protrude through an aperture in the shield , protecting the leds from damaging forces while allowing light to illuminate the landing area .
