Beacon signaling devices

Claim 2

In a beacon signaling device comprising a base, a light producing means adapted to provide an intense beam of white light and a colored cylindrical outer housing mounted on said base and enclosing said light producing means, the improvement comprising said outer housing having at least one ring shaped circumferentially disposed transparent aperture dividing said housing into separate colored sections whereby light emitted from said light producing means and passing through said transparent aperture has substantially greater brightness and intensity than light passing through said colored sections of said outer housing.

Claim 3

A beacon signaling device as defined in claim 1 wherein said light producing means is a plurality of rotating sealed beam lamps each having a light source, an integral parabolic reflector and a lens, said lamps each providing a 5* horizontal by 10* vertical spread of light and wherein said outer housing is provided with at least two circumferentially disposed transparent apertures confined within circumferential area on the surface of said housing corresponding to the curvature of the parabolic reflector.

Claim 4

A beacon signaling device as defined in claim 2 wherein one of said transparent apertures is disposed above the axis of said parabolic reflector and the other of said transparent apertures is disposed an equal distance below the axis of said parabolic reflector thereby providing a balance between signal brightness, wide viewing angle and color identification.

Claim 5

A beacon signAling device as defined in claim 1 wherein said light producing means emits high intensity, short-duration, intermittent flashes of light.

Claim 6

In a beacon signaling device comprising a base, a plurality of rotatable sealed beam lamps each having a light source adapted to provide an intense beam of light, an integral parabolic reflector and a lens, said lamps each providing a 5* horizontal by 10* vertical spread of light, and an outer housing mounted on said base and enclosing said sealed beam lamps, the improvement comprising said outer housing having a plurality of spaced, ring shaped, circumferentially disposed transparent apertures to divide said housing into a plurality of colored and transparent areas, whereby light emitted from said lamps and passing through said transparent areas retains its original brightness and intensity and light passing through said colored areas has a substantially reduced brightness, said apertures being spaced so as to provide a balance between signal brightness and color identification.

Claim 7

In a beacon signaling device comprising a base, a plurality of rotatable sealed beam lamps each having a light source adapted to provide an intense beam of light, an integral parabolic reflector and a lens, said lamps each providing a 5* horizontal by 10* vertical spread of light, and an outer housing mounted on said base and enclosing said sealed beam lamps, the improvement comprising said outer housing having a plurality of spaced, ring shaped, circumferentially disposed transparent apertures to divide said housing into a plurality of colored and transparent areas, whereby light emitted from said lamps and passing through said transparent areas retains its original brightness and intensity and light passing through said colored areas has a substantially reduced brightness, said apertures being spaced so as to provide a balance between signal brightness and color identification.

Claim 8

A beacon signaling device as defined in claim 5 wherein said transparent apertures are positioned on the surface of said housing so as to fall within the circumferential area on said surface corresponding to the curvature of said parabolic reflector.

Claim 9

A beacon signaling device as defined in claim 6 wherein said housing is provided with two transparent apertures, one of said apertures being disposed above the axis of said parabolic reflector and the other of said apertures being disposed an equal distance below the axis of said reflector.
