Abstract

Methods and apparatus for allowing a light beam to shine through top front and top sides of a channel letter while substantially reducing dark spots on a front surface of the channel letter, including: forming the channel letter using a profile with at least one rib; coupling a face plate to a position above the at least one rib, wherein the face plate is formed to allow the light beam to shine through the top front and the top sides; and filling a space above the face plate with a resin material after the channel letter including the face plate is flipped over.

Claims (22)

1 . A method for allowing a light beam to shine through top front and top sides of a channel letter while substantially reducing dark spots on a front surface of the channel letter, the method comprising:

forming the channel letter using a profile with at least one rib;

coupling a face plate to a position above the at least one rib,

wherein the face plate is formed to allow the light beam to shine through the top front and the top sides; and

filling a space above the face plate with a resin material after the channel letter including the face plate is flipped over.

2 . The method of claim 1 , further comprising

performing at least one of drying and hardening of the resin material to form a transparent plate which widens the light beam.

3 . The method of claim 1 , wherein the face plate is formed with one of plastic or acrylic.

4 . The method of claim 1 , wherein the face plate is a hard material.

5 . The method of claim 1 , wherein filling the space above the face plate comprises

adjusting a depth of the resin material so that the light beam covers the substantial portion of the face plate.

6 . The method of claim 1 , wherein the resin material is formed with a gel-like resin material so that it can be poured into the space.

7 . The method of claim 1 , wherein the resin material is formed with pre-hardened material.

8 . A channel letter formed using a profile including at least one rib, the channel letter comprising:

a face plate coupled to a first space above the at least one rib,

wherein the face plate is formed to allow the light beam to shine through a top front and a top sides of the channel letter; and

a layer of resin material disposed in a second space below the face plate.

9 . The channel letter of claim 8 , wherein the face plate is formed with one of plastic or acrylic.

10 . The channel letter of claim 8 , wherein the face plate is a hard material.

11 . The channel letter of claim 8 , wherein a depth of the layer of resin material is adjusted so that the light beam covers the substantial portion of the face plate.

12 . The channel letter of claim 8 , wherein the layer of resin material is formed with a gel-like resin material so that it can be poured into the second space.

13 . The channel letter of claim 8 , wherein the layer of resin material is formed with pre-hardened material.
