Neon light structure 

Neon signs are created by using a glass tube filled with neon gas and applying an electric current through the tube. The structure of traditional neon signs is delicate and distinctive.

A traditional neon sign consists of the following main components: 

Glass tube 

This is the main component of the neon sign. It is made from a bent or U-shaped glass tube. This glass tube contains neon gas, and when an electric current is applied, it glows.

Phosphor coated tubes 

Sometimes, the glass tubes in traditional neon signs are coated with a layer of phosphor on the inside. This coating enhances the color and brightness of the emitted light.

Connectors and controllers

The neon sign requires a connector and controller to be connected to the power supply and adjust the current applied to the glass tube.

Frames and hanging 

Neon signs typically have an outer frame made from materials such as metal or plastic. This frame holds and protects the glass tube and other components of the neon sign. Additionally, neon signs also have mounting points so they can be mounted on walls or connected to other structures.

Recently, technology has brought progress in the field of neon signs with the introduction of LED neon signs. Instead of using glass tubes and neon gas, LED neon signs use LEDs to create an effect similar to traditional neon signs. LED neon has a more flexible and durable structure, and they can be bent and cut as required to create different shapes and letters. This provides greater flexibility in design and color choices.

Traditional neon signs vs LED neon signs 

Traditional neon signs and LED neon signs have differences in structure and features.


Traditional neon signs are made of glass tubes, while LED neon signs are made of flexible plastic materials. The glass tube in traditional neon signs is thinner and more fragile, while the plastic layer of LED neon signs is more flexible and more impact resistant. 


Traditional neon signs are typically not designed to be waterproof and are suitable for indoor use. Meanwhile, LED neon signs are often made with silicon coating, making them waterproof and resistant to external environmental factors. This makes LED neon signs more suitable for both indoor and outdoor applications, even in harsh weather conditions.

Longevity and energy savings 

LED neon signs have a longer lifespan and higher energy efficiency than traditional neon signs. The LEDs in LED neon signs have a much longer lifespan than traditional neon tubes, and they consume less energy, which saves electricity and reduces operating costs.

Design flexibility

Neon LED signs have greater flexibility in shaping and design. Through flexible plastic pipes, they can be bent into complex shapes and produce different letters and images. Traditional neon signs are limited to shape and typically only display letters and simple shapes.

Neon signs have attractive lighting and can become a highlight in any space. However, when considering their outdoor use, it is important to understand their limitations and advantages. Traditional neon signs are usually suitable for indoor use, while LED neon signs provide a more durable and usually waterproof solution. Before making a decision, always consult the manufacturer and consider the specific requirements of your location.
