(57) An emergency lighting fixture (10, 115) especially for industrial environments, generally
comprising a central body (20), at least one source of light constituted by an incandescent
halogen lamp (11, 12) held inside a parabolic reflector (13, 14) and a transparent
shell (15) covering the fixture's (10, 11) central body (20). The reflector (13, 14)
is adjustable by the operator from the outside, after lifting the transparent shell
(15), so as to regulate the direction of the light beam. Each reflector (13, 14) is
associated with a container (131, 141) for a laser light source (17, 17A), capable
of providing an emergency lighting system, for instance in the presence of smoke in
the surrounding environment. A regulating device (465) of the laser light beam (105)
includes a ring nut (125) swiveling in a horizontal plane and a plate (135) for vertical
adjustments, so as to make it possible to position the laser beam (105) within pre-established
angles.
