  • Patent number: 7118245
    Abstract: A trainman's lantern having a reflector that produces both a main beam and secondary illumination for signaling purposes. The reflector includes inner and outer reflective surfaces. An incandescent bulb mounted centrally within the reflector produces the concentrated main beam. A plurality of LEDs mounted around the exterior of the reflector form beams that are reflected outwardly by the outer reflective surface to produce the secondary illumination. Ports in the reflector allow light from the primary bulb to pass outwardly therethrough in a lateral direction so as to augment the light of the LEDs. A transparent housing is mounted around the reflector and LEDs. The housing and reflector are mounted to the lower end of a battery case having a bail for holding the lantern in horizontal or vertical orientations. The combination of the LEDs and incandescent main bulb reduces draw on the battery.
