ELECTRONIC MODULE AND METHOD USED FOR FITTING A LIGHT BEACON ON THE BLADE TIP

摘要

The electronic module (7) for the light beacon on the blade tip is integrated into a lighting system consisting of a power supply (3) located in the rotor (2), a fiber optic transmission system (4) that extends along the length of the blade (1), a converter (5) and a light emitting module (6). The electronic module comprises a power circuit and a control circuit, located at the blade tip (1) and encapsulated for protection against lightning strikes. The operating method of the electronic module (7) selects the blade (1) lighting during the ON interval corresponding to the 120° of the top rotation area, and keeps it switched off and receiving energy during the OFF interval corresponding to the bottom rotation area.
