Abstract
Light signalling device, in particular intended to be mounted on board an aircraft, includes a plurality of light elements mounted on a support and surrounded by a translucent cover, said device including a means of reflecting the light emitted by the light elements disposed near to the light elements, at least one photometric sensor positioned between the support and the reflection means, and a means of comparing a light intensity detected by the photometric sensor with a reference light intensity.
Claims11
A light signaling device, configured to be mounted on board an aircraft, comprising:
- a plurality of light elements mounted on a front side of a support and surrounded by a translucent cover;
- a means of reflecting the light emitted by the light elements disposed near to the light elements;
- at least one photometric sensor arranged on the front side of the support adjacent to the light elements;
- and
- a means of comparing a light intensity detected by the photometric sensor with a reference light intensity;
- wherein the reflection means for reflecting the light emitted in the direction of said photometric sensor is also used to transmit the rays emitted by the light elements towards the outside of the device.
A method of monitoring a light signaling device, the light signaling device comprising a set of light-emitting diodes mounted on a front side of a support and covered by a translucent cover, the method comprising:
- reflecting the light emitted by the diodes;
- detecting the reflected light signal by a photometric sensor arranged on the front side of the support adjacent to the light elements;
- and
- comparing the light intensity of the diodes with a reference light intensity.
