Abstract
A device with a light signaling function including a light-emitting diode designed to emit a first light signal in a first wavelength range in the blue or the ultraviolet, conversion device arranged for converting the first light signal emitted by the light-emitting diode in the first wavelength range into a second light signal in a second wavelength range, a cap arranged for filtering the second light signal with a view to obtaining a color included in a standard color space. The conversion device being chosen so the second wavelength range includes the normal color space.
