Abstract

A portable signaling lantern includes a body having a device for hand-carrying the lantern. A housing is included which defines a battery chamber and includes a lamp on the face of the housing for illuminating an area in the vicinity of the housing with at least two closed loop arrays of solid state lamp devices disposed on the face of the housing about the lamp. The respective closed loop arrays of solid state lamp devices are arranged one inside the other and, when activated, have collective color outputs that are clearly visually distinguishable from a remote viewing position of greater than 1 km from the lantern. The body of the lantern includes a device for selectively activating the lamp or either of the solid state lamp devices utilizing one or more batteries in the battery chamber to power the lamp or array.

Claims

1-15. -15. (canceled)

16. A portable signaling lantern, comprising:

a body including a housing having a battery chamber;

a lamp on a face of said housing actuable for illuminating a zone proximate of said housing;

at least two closed loop arrays of solid state lamp devices disposed on said face of said housing about said lamp, said at least two closed loop arrays of solid state lamp devices being arranged one inside another and, when activated, have collective color outputs that are visually distinguishable from a remote viewing position at a predetermined displacement from said at least two closed loop arrays of said solid state lamp devices; and

,

means for selectively activating said lamp or any of said at least closed loop arrays of said solid state lamp devices utilizing a battery located in said battery chamber for powering said lamp or one closed loop array of said at least two closed loop arrays of said solid state lamp devices.

17. The portable signaling lantern according to claim 16, wherein said solid state lamp devices are light emitting diodes.

18. The portable signaling lantern according to claim 16, wherein said at least two closed loop arrays of said solid state lamp devices, respectively, comprise a red solid state lamp array and a green solid state lamp array, so that said portable signaling lantern is deployable for displaying a “

stop”

or “

go”

signal to a remote viewer.

19. The portable signaling lantern according to claim 18, wherein said green solid state lamp array is inside said array of red solid state lamp array.

20. The portable signaling lantern according to claim 19, wherein said red solid state lamp array are alternately tilted slightly oppositely to normal to said face of said housing.

21. The portable signaling lantern according to claim 18, wherein said red solid state lamp array, when activated, provides a signal visible at a distance greater than 1 km from said portable signaling lantern.

22. The portable signaling lantern according to claim 16, wherein said lamp is an incandescent light.

23. The portable signaling lantern according to claim 16, wherein said lamp is an LED display.

24. The portable signaling lantern according to claim 16, wherein said at least two closed loop arrays of said solid state lamp devices are circular arrays that are substantially concentric with said lamp.

25. The portable signaling lantern according to claim 24, wherein said solid state lamp devices of respective said circular arrays are mutually offset for defining a compact geometric configuration.

26. The portable signaling lantern according to claim 24, wherein said solid state lamp devices of each circular array of said circular arrays are variably inclined for widening an effective divergence angle of a composite beam emitted by said solid state lamp devices of respective said circular arrays.

27. The portable signaling lantern according to claim 16, wherein said at least two closed loop arrays of solid state lamp devices is at least three closed loop arrays of said solid state lamp devices that display at least three different colors of light.

28. The portable signaling lantern according to claim 16, further comprising means for displaying a warning signal.

29. The portable signaling lantern according to claim 16, wherein said means for selectively activating said lamp or any of said at least closed loop arrays of said solid state lamp devices is capable of flashing at least one color of light in a predetermined pattern of light.

30. The portable signaling lantern according to claim 16, wherein said collective color outputs are visible from a distance greater than 1.5 km from said portable signaling lantern.

31. The portable signaling lantern according to claim 16, wherein said body includes means for hand-carrying by a user.
