Abstract

A lighted sign having raised letters or other shapes. The letters are lighted from within and have more than one color visible from the outside of the letter. Each letter has a peripheral translucent wall of a first color and a translucent face plate of a second color. An LED holding frame is held within the peripheral wall and has LED'"'"'s of the same color as the face plate held within the peripheral wall. At the back of the peripheral wall LEDs of a color the same as the peripheral side wall are held.

Claims

1. A multicolored LED lighted sign comprising:

at least one peripheral translucent wall fabricated from a translucent material having a first color, said peripheral translucent wall having an outer peripheral edge and an inner peripheral edge, said at least one peripheral translucent wall being visible from an exterior view of said sign;

an inner LED holding frame having a back wall supporting a first plurality of LEDs emitting a second color, an outwardly directed frame wall extending from said back wall and terminating at an outer flange positioned over the outer peripheral edge of said at least one peripheral translucent wall;

an outer translucent face plate fabricated from a translucent material having said second color which is a different color than said first color of said peripheral translucent wall and said outer translucent face plate having an outer periphery and being held against the outer flange of said inner LED holding frame outer flange at the outer periphery of said outer translucent face plate; and

a second plurality of LEDs emitting said first color which is a different color than that emitted by said first plurality of LED supported by a support frame which is independent of said inner LED holding frame held at the inner peripheral edge of said at least one peripheral translucent wall and wherein said first plurality of LEDs illuminates said outer translucent face plate and said second plurality of LEDs illuminates said at least one peripheral wall.

2. The multicolored LED lighted sign of claim 1 wherein one of said first and second colors is red and the other of said first and second colors is yellow.

3. The multicolored LED lighted sign of claim 1 wherein said inner holding frame has four flat angled sides angled inwardly from said outer flange to said back wall and said back wall being smaller than said outer flange.

4. The multicolored LED lighted sign of claim 3 wherein said inner holding frame is yellow and said outer translucent face plate is red and said first color is yellow and the second color is red.
