Lighting device compatible with night-vision equipment with lateral injection windows for daytime and nighttime light

A lighting device compatible with night-vision equipment, including

• a daytime light source (SD) used in day-vision mode and formed of at least one row of aligned light-emitting diodes (DD);
• a nighttime light source (SN) used in night-vision mode, which is formed of at least one row of aligned light-emitting diodes (DN), with an optical filter that is capable of making the light emitted by said light source compatible with the use of night-vision equipment;
• and
• a light guide (GL) that is configured to diffuse, via a main output face, the light delivered by the current light source according to the current, day- or night-, vision mode, said main output face corresponding to a base (B2) of a main shape of a plate (PP), which is a right rectangular prism, the distance between the two bases of the plate defining a plate height;
• and
• the light guide is assembled together with the daytime and nighttime light sources such that the light emitted by each of the sources is injected into the plate along a longitudinal direction thereof via a lateral face of the plate used as the main input face (FI), which is a lateral face of the plate,
• wherein the main shape of the light guide is extended from said main input face, in the longitudinal direction and heightwise with respect to the plate, by at least one auxiliary prism shape (PA1), which is a right-angled right triangular prism, at least one of the three lateral faces of said auxiliary prism being reflective, and being arranged on the main input face (F1) so as there to define, in the heightwise direction, a first window (I1) for light injection (I1) and a second window (I2) for light injection (I2), each window being reserved for one respective light source from the daytime light source and the nighttime light source.
