(54)	LED traffic signal and optical element therefor

(57) A lighting device includes a housing (28,68) having an open end and a geometrical axis and at least one light source (12,52) disposed along an optical axis. The lighting device further includes an outer optical element (10,50) having a focal point and closing the open end of the housing, the optical element comprising a converging outer surface and a diverging inner surface that cooperates with the light coming from the inner optical element. Additionally, the lighting device includes an inner optical element between the light source and the outer optical element, the inner optical element redirecting light from a light source that is offset from the focal point toward the outer optical element.
