ABSTRACT:
The flush-type airport runway light according to the invention comprises an embedded seating, a lid fixed on the seating, and an optical unit which is removable through an opening in the center of the lid and which is housed, while in its working position, so as to be on the same upper level as the lid and; equipped with means for guiding the optical unit in vertical translation, as well as means for interlocking the optical unit and the lid arranged in such a way that the locking or unlocking control of said means causes an upward or downward vertical translational motion of said unit between a grasping position in which the unit protrudes sufficiently from the upper level of the lid to be grasped and removed from its working position, and vice-versa.
