Abstract
A hybrid illuminated indicator sign for visually displaying indicators when the hybrid illuminated indicator sign is electrically powered and for at least a period of time when the hybrid illuminated indicator sign is no longer electrically powered comprises a light guide plate having a light receiving edge and a light emitting face, an intermediate translucent photo-luminescent layer at least partially covering the light emitting face of the light guide plate, an outer indicator layer at least partially covering the intermediate translucent photo-luminescent layer, and an electrically powered light source mounted adjacent the light receiving edge of the light guide plate.

A hybrid illuminated indicator sign for visually displaying indicators when the hybrid illuminated indicator sign is electrically powered and for at least a period of time when the hybrid illuminated indicator sign is no longer electrically powered, the hybrid illuminated indicator sign comprising:
- a light guide plate having a light receiving edge and a light emitting face;
- a frame substantially surrounding the light guide plate
- a photo-luminescent member secured to the frame;
- an outer indicator layer secured to the frame adjacent the light emitting face of the light guide plate;
- and
- an electrically powered light source mounted within the frame adjacent the light receiving edge of the light guide plate;
- wherein in a powered-on state, the electrically powered light source is configured to emit light which causes photo-excitation of the photo-luminescent member, the emitted light entering the light guide plate through the light receiving edge and re-directed through the light emitting face to the outer indicator layer, and partially through the outer indicator layer to be visible from the exterior of the hybrid illuminated indicator sign;
- and
- wherein in a powered-off state, the electrically powered light source is configured to stop emitting light, and light from the photo-excited photo-luminescent member is transmitted partially through the outer indicator layer to be visible from the exterior of the hybrid illuminated indicator sign.
A hybrid illuminated indicator sign for visually displaying indicators when the hybrid illuminated indicator sign is electrically powered and for at least a period of time when the hybrid illuminated indicator sign is no longer electrically powered, the hybrid illuminated indicator sign comprising:
- a light guide plate having a light receiving edge and a light emitting face;
- a frame substantially surrounding the light guide plate
- a photo-luminescent member secured to the frame;
- an outer indicator layer secured to the frame adjacent the light emitting face of the light guide plate;
- an electrically powered light source mounted within the frame adjacent the light receiving edge of the light guide plate;
- and
- a mounting apparatus comprising:
- a structure-engaging plate;
- a bayonet mounting bracket;
- a canopy securable to the bayonet mounting bracket;
- a housing including an internal mounting bracket;
- and
- at least one threaded fastener extending through a co-operating aperture in the canopy through a co-operating aperture in the internal mounting bracket for threaded engagement by a co-operating threaded fastener.
- wherein in a powered-on state, the electrically powered light source is configured to emit light which causes photo-excitation of the photo-luminescent member, the emitted light entering the light guide plate through the light receiving edge and re-directed through the light emitting face to the outer indicator layer, and partially through the outer indicator layer to be visible from the exterior of the hybrid illuminated indicator sign;
- and
- wherein in a powered-off state, the electrically powered light source is configured to stop emitting light, and light from the photo-excited photo-luminescent member is transmitted partially through the outer indicator layer to be visible from the exterior of the hybrid illuminated indicator sign.
A hybrid illuminated indicator sign system comprising:
- a plurality of hybrid illuminated indicator signs;
- an electrical power controller circuit having a plurality of power outputs connected in power supplying relation to each of the plurality of hybrid illuminated indicator signs;
- wherein said electrical power controller circuit is operable to provide electrical power from the plurality of power outputs to the plurality of hybrid illuminated indicator signs in a power cycle that comprises a plurality of power sub-cycles, in which in each of the plurality of power sub-cycles electrical power is provided to one of the hybrid illuminated indicator signs and the remaining hybrid illuminated indicator signs are not provided electrical power, and subsequent power sub-cycles provide electrical power to a different hybrid illuminated indicator sign.
