Sub-assembly for searchlight signal, and associated assembly
First Claim
1. A sub-assembly for a searchlight signal comprising:
- three distinct light emitting diodes andan interface module for connecting the three light emitting diodes to a controller, the controller being adapted to control one bulb and three filters,the interface module comprising;
a light input adapted to receive a signal for feeding a light emitting diode,a selecting circuitry interposed between the light input and the light emitting diodes,the selecting circuitry being adapted to select one light emitting diodes to be fed by the signal received by the light input,a first relay having an active position and an inactive position, anda second relay having an active position and an inactive position,the first relay and the second relay controlling the selecting circuitry, such that;
when the second relay and the first relay are in the inactive position, the light input is fed to a first LED,when the first relay is in the active position, the light input is fed to a second LED, andwhen the second relay is in the active position, the light input is fed to a third LED.

Abstract
The invention relates to a sub-assembly for a searchlight signal comprising three distinct light emitting diodes and an interface module for connecting the three diodes to a controller.
The interface module comprises:
a light input adapted to receive a signal for feeding a light emitting diode,
a first relay having an active position and an inactive position, and
a second relay having an active position and an inactive position,
such that:
when the second relay and the first relay are in the inactive position, the light input is fed to a first LED,
when the first relay is in the active position, the light input is fed to a second LED, and
when the second relay is in the active position, the light input is fed to a third LED.
