<p>The exterior luminaire has a device housing (10) which consists of a support (11) and a hood (12). The support (11) has longitudinally extending rails (29) in which engagement parts (31, 32) of the hood (12) are guided. As a result, the hoods can be displaced from the support in the longitudinal direction for the purpose of opening. Outlet points (33, 34) are provided on the rails (29) so that the hood (12) can be lifted off in a specific displacement position. <IMAGE></p>
