Light projector, especially for vehicles, having an enhanced mechanical structure

摘要

The headlamp (30) is fitted into a holder (40) in a hole (11) through the concave reflector (10), and sealed with an O-ring (70) compressed between the holder and a ring (24) screwed on to a collar (12) at the back of the reflector. The ring has a U-section profile with a longer outer limb (22) and a shorter inner limb on opposite faces of the collar. Its outer face (21) co-operates with e.g. a three-lipped seal (51) on the inner rim of the annular shade (50).
