PORTABLE ILLUMINATED SIGN
A portable illuminated sign is disclosed. The sign includes a sign portion, the sign portion comprising indicia, and an internal light source comprising one or more LEDs in edge-lighting relationship with a diffuser panel underlying a visible area of the indicia to be illuminated; and a handle affixed to the sign portion, the handle comprising a power source for the internal light source.
1 . A portable illuminated sign, comprising:
a sign portion, the sign portion comprising indicia, and
an internal light source comprising one or more LEDs in edge-lighting relationship with a diffuser panel underlying a visible area of the indicia to be illuminated: and
a handle affixed to the sign portion, the handle comprising a power source for the internal light source.
2 . The sign of claim 1 , the internal light source further comprising a reflector panel positioned adjacent the diffuser panel for reflecting light emanating from the diffuser towards the indicia.
3 . The sign of claim 2 , further comprising a further diffuser panel and wherein the reflector panel is double-sided with two reflective surfaces facing away from each other, each of the two diffusers panels positioned adjacent a reflective surface of the reflector panel.
4 . The sign of claim 1 , further comprising an indicia carrier panel positioned between the indicia and the diffuser panel, the indicia affixed to the indicia carrier.
5 . The sign of claim 4 , wherein the indicia carrier panel and the diffuser panel have a common shape and size.
6 . The sign of claim 4 , wherein the indicia, the indicia carrier panel, and the diffuser panel have a common shape and size.
7 . The sign of claim 1 , wherein one or more weather tight seals are provided along a perimeter of the sign portion.
8 . The sign of claim 1 , wherein a weather tight sealing element spans a width of the sign portion and extends around a perimeter of the sign portion.
9 . The sign of claim 1 , wherein a light concentrator is positioned between the one or more LEDs and the diffuser panel to concentrate light from the LEDs into the diffuser panel.
10 . The sign of claim 9 , wherein the light concentrator has an elliptic profile.
11 . The sign of claim 9 , wherein the light concentrator has a one or more sides configured as an internal Fresnel reflector.
12 . The sign of claim 9 , wherein the light concentrator is faceted.
13 . The sign of claim 9 , wherein the light concentrator is configured as a refracting lens.
14 . The sign of claim 9 , wherein the light concentrator has a slot to receive the diffuser panel.
15 . The sign of claim 9 , wherein the light concentrator has a slot to receive the one or more LEDs.
16 . The sign of claim 1 , the sign portion further comprising a frame surrounding the indicia.
17 . The sign of claim 16 , wherein the frame defines the visible area of the indicia to be illuminated.
18 . The sign of claim 16 , wherein the frame seals the sign portion in a weather tight manner.
19 . The sign of claim 16 , wherein the handle is affixed to the frame.
20 . The sign of claim 1 , wherein the indicia comprise two indicia, each of the two indicia positioned on a respective opposite side of the diffuser panel.
21 . The sign of claim 20 , wherein a respective indicia carrier panel is positioned between each indicia and the diffuser panel, each indicia affixed to a respective indicia carrier panel.
