Abstract

A physically-discrete sign component comprises an internally-electrically-illuminated alphabetic character having a front-facing profile and at least one connecting bar disposed at least substantially horizontally with respect to the front-facing profile of the alphabetic character and at least partially within the front-facing profile of that alphabetic character. By one approach the physically-discrete sign component includes two of the connecting bars. If desired, these two connecting bars are disposed at least substantially parallel to one another. By one approach, a first one of the connecting bars extends partially, but not wholly, above an upper periphery of the aforementioned front-facing profile while the second connecting bar extends partially, but not wholly, below a lower periphery of the front-facing profile. The connecting bars can include a connecting-bar interface configured to physically and electrically interconnect to an adjacent sign component.

Claims (26)

1. An apparatus comprising:

a physically-discrete sign component including:

an internally-electrically-illuminated alphabetic character having a front-facing profile;

at least two connecting bars that are disposed at least substantially parallel to one another and that are each disposed at least substantially horizontally with respect to the front-facing profile of the alphabetic character and at least partially within the front-facing profile of the alphabetic character, wherein a first one of the connecting bars extends partially, but not wholly, above an upper periphery of the front-facing profile while a second one of the connecting bars extends partially, but not wholly, below a lower periphery of the front-facing.

2. The apparatus of claim 1 wherein the alphabetic character comprises, at least in part, a light diffuser having a form factor that conforms to the alphabetic character, the apparatus further comprising:

a plurality of light-emitting diodes disposed behind the light diffuser.

3. The apparatus of claim 2 wherein the internally-electrically-illuminated alphabetic character comprises a faux-neon internally-electrically-illuminated alphabetic character.

4. The apparatus of claim 1 wherein the apparatus includes a plurality of the physically-discrete sign components.

5. The apparatus of claim 2 wherein at least some of the physically-discrete sign components have a front-facing profile having a proportional font-based width.

6. The apparatus of claim 1 wherein the physically-discrete sign component has a back surface that is at least substantially planar.

7. An apparatus comprising:

a physically-discrete sign component including:

an internally-electrically-illuminated alphabetic character having a front-facing profile;

at least two connecting bars that are each disposed at least substantially horizontally with respect to the front-facing profile of the alphabetic character and at least partially within the front-facing profile of the alphabetic character, wherein at least two of the connecting bars each include a bridging electrical conductor wherein a first one of the bridging electrical conductors comprises a positive electrical power rail and a second one of the bridging electrical conductors comprises a negative electrical power rail, and wherein both the first and second connecting bars each include a connecting-bar interface configured to physically and electrically interconnect to another such connecting bar of another physically-discrete sign component.

8. The apparatus of claim 7 wherein the connecting-bar interfaces for the first connecting bar are at least substantially a mirror image of the connecting-bar interfaces for the second connecting bar to thereby discourage connecting the first connecting bar to a second connecting bar of another of the physically-discrete sign components.

9. The apparatus of claim 7 wherein the connecting-bar interfaces include at least one of an electrically-conductive blade and an electrically-conductive blade receiver.

10. The apparatus of claim 7 wherein the connecting-bar interfaces include at least one of a threaded-engagement member and a threaded-engagement member receiver.

11. The apparatus of claim 7 wherein the connecting-bar interfaces comprise, at least in part, a stepped interface.

12. The apparatus of claim 7 further comprising:

at least one end cap configured and arranged to connect to at least one of the connecting-bar interfaces.

13. The apparatus of claim 12 wherein the end cap includes, at least in part:

a power-input interface;

a power-output interface;

a power on/off switch.

14. The apparatus of claim 13 wherein the power-input interface, the power-output interface, and the power on/off switch are disposed on a side edge of the end cap.

15. The apparatus of claim 13 further comprising another end cap that does not include a power-input interface, a power-output interface, and a power on/off switch.
