Abstract:
An obstruction lighting system for emitting a dual high intensity light with essentially no downward component comprising, in combination:a housing having a rear vertical plate with vertical edges and horizontal upper and lower edges and upper and lower horizontal plates extending forwardly from the horizontal edges and with reflective vertical side plates extending forward from the vertical edges coupling the upper and lower horizontal plates and with a cover parallel with the rear vertical plate to define a chamber there within; a lower light source in a generally cylindrical configuration within the chamber and having ends supported by the side plates, the lower light source being a powerful pulsed white xenon gas discharge light, the lower light source having an axis within a lower horizontal lane; a lower reflector having ends supported by the side plates and including a lower component in a semi-circular configuration with an axis of rotation coextensive with the axis of the lower light source and with upper edges terminating at the lower horizontal plane and with a forward edge adjacent to the cover and a rearward edge adjacent to the rear vertical plate, the lower reflector having an upper component extending upwardly and forwardly from the rearward edge of the lower component in a parabolic configuration and with a terminal edge above and forwardly of the forward edge; an upper light source located vertically displaced above and parallel with the lower light source, the upper light source being a powerful pulsed white xenon gas discharge light, the upper light source having an axis within an upper horizontal plane; an upper reflector located vertically displaced above the lower reflector, the upper reflector having ends supported by the side plates and including a lower component in a semi-circular configuration with an axis of rotation coextensive with the axis of the upper light source and with upper edges terminating at the upper horizontal plane and with a forward edge adjacent to the cover and a rearward edge adjacent to the rear vertical plate, the upper reflector having an upper component extending upwardly and forwardly from the rearward edge of the lower component in a parabolic configuration and with a terminal edge forwardly of the forward edge; and a red filter in contact with the cover having side edges and an upper edge coextensive with the side edges and top edge of the cover and with a lower edge adjacent to the upper most extent of the lower reflector.
