ABSTRACT:
An armored light projector is provided, having a linear light source arranged at the focal axis of a reflector unit capable of projecting a light beam of parallel rays having a substantially rectangular cross-section, the light source being mounted in a rear bottom recess of the reflector unit such as not to be directly visible from the front of the projector. The recess within which the light source is mounted is shielded by an armor assembly against direct impact of a projectile aimed at the front or at the sides of the projector. The projector has shock-absorbing suspension means capable of supporting the linear light source and affording means allowing its connection to a suitable external electric power supply. Means may be provided for protecting the rear and the top of the reflector unit against shocks and or blows, and means may be also provided for improving the cooling of the projector. At the frontal light beam output opening of the reflector unit a refractor unit may be provided to improve the directionality of the light beam rays.
