Strobe light unit and aircraft comprising the same

摘要

A strobe light unit, particularly wing anti-collision strobe light unit for an aircraft, comprises at least one light source, particularly at least one LED; a reflector element, the at least one light source and the reflector element being configured for projecting light into a desired range of directions; and a stray light blocking element for blocking stray light from being projected into undesired directions, the stray light blocking element attached to the reflector element or to a base portion of the strobe light unit.

1. A wing anti-collision strobe light unit for an aircraft, comprising:
at least one light source, particularly at least one LED; a reflector element, the at least one light source and the reflector element being configured for projecting light into a desired range of directions; and a stray light blocking element for blocking stray light from being projected into undesired directions, the stray light blocking element attached to the reflector element or to a base portion of the strobe light unit;wherein the stray light blocking element comprises a substantially planar main portion, which substantially planar main portion extends into a radial direction from the at least one light source, such that at least one of parallel and radial light beams projected into the desired range of directions are substantially unaffected by the stray light blocking element and such that stray light beams of an undesired range of directions, particularly stray light beams reflected by an additional transparent cover or an additional cover lens, are blocked; andwherein the substantially planar main portion of the stray light blocking element includes an angle of 30 to 60° with respect to an axis of symmetry of the reflector element.
