The inventive LED-illuminated sign structure includes a frame, an outer shell and a plurality of separate LED emitters. The frame includes two opposite main support panels each having an upright outward surface, and shell-supporting members. The outer shell has a pair of opposite translucent sidewalls each extending along and is spaced from the respective outward surface. The LED emitters are spaced on each outward surface such that the translucent sidewalls are illuminated substantially entirely. The frame defines an open region for passing reflected light within the frame structure to and through the opposite translucent sidewall. The LED illuminator includes an LED emitter on a mounting surface, a one-piece lens member over the LED emitter and including a lens portion and a flange portion, and a gasket between the flange portion and the mounting surface. The lens member has a restraining ridge positioned to press the LED-emitter wires and the gasket against the mounting surface such that the wire portions between the ridge and the LED emitter remain in substantially fixed position regardless of wire movement beyond the restraining ridge. |
