Patent

CA 2493480

Low light level illumination is applied to rotary blades (102, 202) of vehicles to increase visibility to minimize ground injuries. Either photoluminescent paint (208) or photoluminescent film (104) may be affixed to rotary blades (102, 202) in use to help deter accidents. An electro- luminescent film (509) may be integrated into future rotary blades (502) to provide greater visibility without making the vehicle vulnerable to detection.

L'invention porte sur la signalisation de faible intensité lumineuse de pales tournantes (102, 202) de véhicules, pour en accroître la perception et réduire les possibilités d'accidents au sol. On peut prévoir à cet effet l'application sur lesdites pales (102, 202): soit d'une peinture (208) luminescente, soit d'un film luminescent (104). On peut également intégrer à des pales futures (502) un film électroluminescent (509) plus lumineux, mais ne rendant pas le véhicule plus vulnérable à la détection.
