Abstract:
A delineator lighting apparatus comprising:a light source for producing light; and a plurality of longitudinally-extending light-emitting elements, each light-emitting element having a length and comprising: a plurality of first light-emitting zones disposed along the length, each first light-emitting zone emitting light with a first light-emission intensity; and a plurality of second light-emitting zones disposed along the length and interspersed within the plurality of first light-emitting zones, each second light-emitting zone emitting light with a second light-emission intensity different from the first light-emission intensity; in which the plurality of first light-emitting zones and the plurality of second light-emitting zones are arranged in a regular pattern along the length of each light-emitting element, wherein the pattern of the first and second light-emitting zones of one the elements is offset from the pattern of first and second light-emitting zones of another one of the elements by a distance along the length of each element; wherein at any time during operation, at least one light-emitting element emits light along substantially its entire length.
