How Are LED Neon Signs Made?

LED neon signs have become increasingly popular in recent years, with their vibrant colors and eye-catching designs. But have you ever wondered how these signs are made? In this blog post, we will take a closer look at the process of creating LED neon signs and the technology behind them.

What is LED Neon?

LED neon is a modern alternative to traditional glass neon signs. Instead of using glass tubes filled with gas, LED neon signs are made using flexible LED strips that mimic the look of neon. These strips are encased in a durable, translucent silicone jacket that diffuses the light and creates a neon-like glow.

The Manufacturing Process

The manufacturing process of LED neon signs involves several steps:

Design and Artwork

The first step in creating an LED neon sign is designing the artwork. This can be done using graphic design software or by hand. The design is then converted into a digital file that can be used by the LED neon sign manufacturer.

LED Neon Strip Production

The LED neon strips used in the signs are produced by placing individual LED chips onto a flexible circuit board. These chips are then covered with a protective layer and encapsulated in a silicone jacket. The silicone jacket not only protects the LEDs but also diffuses the light to create a uniform glow.

Bending and Shaping

Once the LED neon strips are ready, they are bent and shaped to form the desired design. This can be done by hand or using specialized bending machines. The flexibility of the LED neon strips allows for intricate and complex designs to be created.

Mounting and Wiring

After the LED neon strips have been shaped, they are mounted onto a backing board or frame. The strips are secured in place using adhesive or clips. The wiring is then connected to the power source, allowing the LED neon sign to light up.

Quality Control

Before the LED neon sign is ready to be shipped, it undergoes a thorough quality control process. This includes checking for any defects in the LED strips, ensuring that the wiring is properly connected, and testing the sign to make sure it lights up correctly.


LED neon signs are made using flexible LED strips encased in a silicone jacket. The manufacturing process involves designing the artwork, producing the LED neon strips, bending and shaping the strips, mounting and wiring, and conducting quality control checks. The result is a vibrant and durable sign that can be used for a variety of purposes, from advertising to decoration.
