What is a backlit sign ?

The backlit letters have a metal letter shell made in 3D, stainless steel or 3D CNC lettering shell 
and LED inside. Backlit channel letters, also known as reverse channel letters, have a 
dramatic effect, making letters seem to "float" on the wall, which is very beautiful and eye-catching. 
It is one of the most common LED lighting letters and is widely used in many applications.

How do you make a backlit sign?

Luxury backlight metal letter: manufacturing 3D metal letter shell, stainless steel, can be painted
powder coated, mirror polished, brush and plated. Led interior is the light source, and some acrylic back 
plates expose letter shell. This model backlit letter sign does not need to close the wall, and people 
can see the lighting directly from visible acrylic back panel. The brightness is very good.

Classic backlight metal letters: manufacturing 3D metal letter housing, stainless steel, paintable 
powder coating, mirror polishing, brush and plating complete, led as light source inside, acrylic back 
plate in letter shell for uniform lighting. This model backlit letter must be closed on the back wall so 
that light can pass through the acrylic backing plate and reflect the person it can see before the back wall. 
Considering the reflectivity of the walls, the brightness of the model is good, but it is worse than the luxury 
model. Although the aura effect is still beautiful, it is worse than the luxury car. We recommend that this type 
of backlit letter close the wall by about 10 mm to 20 mm (0.4 "~0.8") to achieve the best aura effect.

Backlit acrylic letter: color drawing numerical control engraves the letter shell of visible acrylic back plate, 
and the LED is the light source inside. The model backlight letter sign does not need to close the walls, 
and people can see the lighting directly from the visible acrylic back panel. The brightness is very good, 
and the ring effect is very strong. Because the letter shell is made by numerical control carving technology, 
the letter shell is very exquisite, can achieve various 3D effects, and it is very suitable for close-up display.

3D printed channel letters: 3D printing backlit channel letters is the new 3D printing application in making channel
Letters.The pre-designed channel files is input into a 3d printer, and it will print it letter shells. Adding the post-
processing, the backlit letter is made.Compared to the above three methods, 3D printing making letters is faster
and lower cost.
