CLAIMS
I. A sign carrying element for an illuminated sign, the sign carrying element arranged to extend from a base and including a first edge adjacent to the base, a second edge parallel to the first edge and an internal light source located towards the second edge, the sign carrying element including light transmission means to distribute light emitted from the light source evenly through sign carrying surfaces of the sign carrying element and a light emitting region in the vicinity of the second edge through which light from the light source is emitted to provide emergency illumination of an area in the vicinity of the sign carrying element.
2. The sign carrying element as claimed in claim 1, wherein the light source is in the lower, one third of the sign carrying element.
3. The sign carrying element as claimed in claim 1, wherein the light source is adjacent to the second edge of the sign carrying element.
4. The sign carrying element as claimed in claim 1, 2, or 3 wherein the sign carrying element comprises a transparent or translucent body with the light conducting elements integrally formed therein.
5. The sign carrying element as claimed in claim 4, wherein diffusing material is applied to regions of the body to improve the even distribution of light from the sign carrying surfaces.
6. The sign carrying element as claimed in claim 4, or 5 wherein masking material is applied to regions of the body where light emission is not required.
7. The sign carrying element as claimed in any one of claims 4 to 6, wherein the body comprises a pair of half shells, moulded in transparent or translucent plastics material.
8. The sign carrying element as claimed in claim 7, wherein the body surrounds a pair of lamps located internally adjacent to the first and second edges of the body at two extremities of the body.
9. The sign carrying element as claimed in claim 8, wherein the two extremities of the body at which the pair of lamps are located the upper and lower extremities of the body when in use.
10. The sign carrying element as claimed in claim 7, 8, or 9 wherein the body is moulded in acrylic material.
II. The sign carrying element as claimed in claim 7, 8, or 9 wherein the body is moulded in poly carbonate material.

12. The sign carrying element as claimed in any one of claims 4 to 6, wherein the sign carrying element comprises an opaque external structure with apertures where the sign carrying surfaces are' located, with light transmitting regions are located in the structure to direct light from the light receiving surface to the sign carrying surface.
13. The sign carrying element as claimed in any one of claims 4 to 12, wherein the light transmitting region comprises a light transmitting core.

14. The sign carrying element as claimed in any one of claims 4 to 13, wherein the light transmitting region comprises an open space.
15. The sign carrying element as claimed in any one of claims 4 to 14, wherein the light transmitting region comprises a lens
16. The sign carrying element as claimed in any one of claims 4 to 15, wherein the light transmitting region comprises a diffuser.
17. The sign carrying element as claimed in any one of claims 1 to 16 wherein the light source or one of the light sources, is a fluorescent tube.

18. The sign carrying element as claimed in claim 17 wherein the light source or one of the light sources, is an 8 watt fluorescent tube.
19. The sign carrying element as claimed in any one of claims 1 to 16 wherein the light source or one of the light sources, is a cold cathode lamp. 20. The sign carrying element as claimed in any one of claims 1 to 16 wherein the light source or one of the light sources, is a plurality of LEDs.

21. The sign carrying element as claimed in any one of claims 1 to 16 wherein the light source or one of the light sources, is an incandescent lamp.

22. The sign carrying element as claimed in any one of claims 1 to 16 wherein the light source or one of the light sources, is a neon lamp .
23. The sign carrying element as claimed in any one of claims 1 to 22 further comprising mounting means for removably attaching the sign carrying element to a base in which power supply electronics and control electronics are housed.
24. The sign carrying element as claimed in any one of claims 1 to 22 further comprising power supply electronics and control electronics housed within the body.
