ABSTRACT:
The lighting device has a housing (10) bounding an interior space (14). An air passage (26) connected to the outer atmosphere is provided in the housing to vent the interior space (14). An exteriorly projecting extension (30) has an inner duct (28) connected with the air passage (26) and extends from the housing. A cap (42) is secured to the exteriorly projecting extension (30) and together with the exteriorly projecting extension (30) forms an outer duct (50) connected with both the outer atmosphere and the inner duct (28). The cap (42) has a resilient finger (48) extending into the inner duct (28) of the exteriorly projecting extension (30) which is elastically pivotable transverse to the insertion direction (52) of the cap (42) and which has an opening (49) so that it locks on a projection (36) protruding from a longitudinal inner wall (32) bounding the inner duct (28). After assembly the cap (42) is no longer removable without being destroyed and thus its loss is reliably prevented without additional assembly effort and expense.
