Abstract:
A shroud for a light producing element, which minimizes damage in the event of a non-passive failure of the light producing element, the shroud comprising:an elongated reflecting portion having a curved cross-section; and an elongated light-transmissive portion having a curved cross-section, the reflecting portion and the light-transmissive portion being separately formed and mechanically held together or fused together to form a generally cylindrical body having first and second open ends, a cavity in which the light producing element is disposed being between the reflecting portion and the light-transmissive portion, such that light emitted from the light producing element in a first direction strikes the reflecting portion without first striking the light-transmissive portion and light emitted from the light producing element in a second direction strikes the light-transmissive portion without first striking the reflecting portion.
