LED Neon Signs – Custom Neon Lettering
LED neon signs use modern technology to produce illuminated lettering, logos and decorative lines with the distinctive appearance of traditional neon. Flexible lighting elements allow a variety of typographic and graphic forms with a continuous, uniform lighting effect.
Metaling DOO Belgrade manufactures custom LED neon signs and illuminated lettering to the client's artwork and requirements. We make signs for restaurants, cafés, bars, shops, commercial premises, shop windows and decorative interior lighting.
LED neon is particularly suitable for signs where light follows the outlines of letters or logos. Depending on the project, lighting elements can be mounted on a suitable backing, formed into separate graphic elements or integrated into other sign structures.
Alongside modern LED neon systems, we also present traditional glass-tube neon technology, its characteristics and differences from LED designs below.
LED Neon Signs – Manufacturing Technology and Benefits
LED neon is a flexible lighting system in which LED light sources are housed inside a suitable profile with a translucent surface. The profile can be made from silicone or another suitable polymer, depending on the manufacturer and product type.
The profile's special structure diffuses the light so that individual LEDs are not prominently visible. The result is a continuous illuminated line that can follow lettering, symbols or decorative outlines.
Unlike traditional glass neon tubes, flexible LED neon does not require heat-forming glass or gas discharge to produce light.
Benefits of LED Neon Signs
- Flexibility: illuminated lines can be shaped into letters, logos and other graphic forms.
- Continuous light: the translucent profile gives the illuminated line a uniform appearance.
- Different colours: light colour is selected to match the visual identity and available LED neon models.
- Compact construction: signs can have relatively little depth compared with some conventional illuminated sign structures.
- Design flexibility: individual letters, short messages, logos and decorative shapes can be made.
- LED technology: enables energy efficiency according to the selected system's characteristics.
- Servicing: electrical components and their replacement are planned around the sign's construction.
Exact electrical and lighting characteristics depend on the selected LED neon model. Voltage, power, dimensions, protection rating and application conditions are therefore determined from the technical documentation for the specific components.
Custom LED Neon Lettering Manufacture
Manufacturing an LED neon sign begins with an assessment of the lettering or logo. The artwork determines the shape of the illuminated lines, their dimensions, colour, connection method and suitable backing.
Correct outline preparation is particularly important for a quality appearance, because flexible LED neon has limits on minimum bending radius, bending direction and how individual details are formed.
Shaping Letters and Illuminated Outlines
LED neon can form individual letters, stylised lettering, logos, line drawings and other decorative elements.
The appearance depends on typography, illuminated line width, spacing between elements and the selected material's characteristics.
Complex shapes require checks of sharp angles, small internal openings, short segments and transitions between directions. Where necessary, the artwork is adapted to the selected technology's capabilities.
Preparing Backings and Mounting Components
LED neon lettering can be made on suitable acrylic or other material backings, depending on its purpose and desired appearance.
The backing can be clear, coloured or shaped to the lettering outline. The lighting elements' mounting method is defined by the construction and installation location.
Suitable clips, brackets, channels or other LED profile fixings can be specified for installation.
Electrical Connections and Power Supplies
LED neon signs require suitable power supplies and correctly connected lighting segments.
Many flexible LED neon systems use low-voltage power, such as 12 V or 24 V, while other designs can have different electrical characteristics. The mains connection and the lighting element's operating voltage are not necessarily the same.
Power supplies, electrical protection, individual segment lengths and connection methods are selected according to the manufacturer's specifications and sign construction.
Electrical work and sign connections must be entrusted to suitably trained professionals.
Technical Characteristics of LED Neon Signs
LED neon systems differ in profile dimensions, power, supply voltage, light intensity, colour and protection rating.
The following parameters are considered when selecting a system for a particular sign:
- Profile dimensions: the lighting element's width and height determine its appearance and shaping options.
- Power per metre: depends on the LED neon model and required lighting characteristics.
- Operating voltage: selected from the installed lighting system's technical data.
- Light colour: various single-colour versions can be used, depending on available models.
- Minimum bending radius: determines the feasibility of curved lettering sections.
- Bending direction: individual LED neon profiles are designed for particular shaping directions.
- Protection rating: selected according to indoor or outdoor conditions.
- Control options: dimming and other lighting effects depend on compatibility between the LED system and control equipment.
LED Neon Sign Colours
LED neon signs can produce different light colours. Typical choices include red, blue, green, yellow and white, depending on available lighting profiles.
Light colour is selected according to the brand's visual identity, sign purpose and desired ambient effect.
Some LED systems allow colour changes or intensity control, but these functions require compatible components and a specific technical solution.
LED Neon for Outdoor Use
Outdoor applications require lighting profiles, power supplies, cables and connections suitable for the expected environmental conditions.
A protection rating, such as IP67 for certain products, refers to specific declared components and test conditions. It does not automatically mean that the complete assembled sign has the same rating.
Outdoor installation feasibility is therefore checked against the selected system, electrical installations, fixing method and weather exposure.
Where Are LED Neon Signs Used?
LED neon signs are particularly suited to interiors and decorative lighting in spaces where lettering forms part of the visual identity and atmosphere.
LED Neon Signs for Restaurants, Bars and Cafés
Hospitality venues use LED neon to highlight restaurant names, short messages, slogans and decorative graphics.
Signs can be positioned behind bars, on decorative walls, in windows or other interior locations selected for visibility and atmosphere.
LED Neon Lettering for Shops and Windows
Retail premises can use LED neon signs to highlight logos, special messages, product names and other elements of visual communication.
The ability to shape illuminated outlines makes them suitable for various graphic forms and short messages.
Decorative Interior Lighting
LED neon is used to decorate walls, highlight particular areas and create lighting elements that complement the interior design.
Depending on the project, geometric lines, symbols, stylised graphics and other decorative outlines can be formed.
Architectural Lighting Lines
Suitable flexible LED systems can highlight architectural outlines, decorative elements and particular parts of a building.
For these applications, the lighting profile must suit the planned bending radius, installation method and environmental conditions.
Traditional Glass-Tube Neon Signs
Traditional neon signs are made from specially formed glass tubes in which electrical discharge through a suitable gas produces light.
Different light colours and visual effects can be achieved depending on the gas, tube characteristics and any fluorescent coatings.
Traditional neon is used for lettering, logos, decorative elements and architectural lighting. Its appearance is characterised by a continuous illuminated line formed by a glass tube.
Manufacturing Glass Neon Tubes
Glass tubes are shaped to the outlines of lettering or other graphics. The process requires specialised glass forming, tube preparation and an appropriate electrical power system.
Tube diameter, bending radii and shaping possibilities depend on the glass type, construction and project requirements.
Traditional tubes can be made in different diameters; the availability of specific dimensions and suitable components should be checked for the planned design.
Lighting and High-Voltage Power Supplies
Traditional neon tubes use a suitable high-voltage power system adapted to the characteristics and overall construction of the installation.
Unlike common low-voltage LED neon systems, traditional gas tubes require specific design of the power supply, insulation, fixings and protection.
Work on these systems, including installation, connection, testing and servicing, should be carried out by appropriately qualified professionals.
Traditional Neon Durability and Maintenance
A traditional neon sign's service life depends on the quality of its tubes, electrodes and power supplies, operating conditions and maintenance.
Glass elements require careful handling and suitable protection against mechanical damage. Access to components for possible servicing must be included in sign planning.
No single service life can be guaranteed for every traditional neon sign without information about the specific components and conditions of use.
LED Neon or Traditional Neon – Which Should You Choose?
LED neon and traditional glass neon both create illuminated lines and lettering, but differ in construction, electrical supply, manufacture and maintenance.
- LED neon: a flexible profile with LED light sources and a suitable translucent surface.
- Traditional neon: glass tubes producing light through electrical discharge in a gas.
- Shaping: LED neon follows the flexible profile's permitted bending radii, while traditional neon requires purpose-shaped glass.
- Power supply: many LED neon systems use low-voltage sources, while traditional neon uses high voltage.
- Appearance: both technologies create illuminated lines but differ in optical characteristics and final visual effect.
- Servicing: maintenance and component replacement procedures differ according to technology and construction.
LED neon is often practical for decorative interior lettering. Where the aim is the specific appearance of traditional glass neon, conventional technology should be considered.
LED Neon Sign Installation and Maintenance
Installation depends on lettering size, substrate, lighting element construction and location.
An LED neon sign can be mounted on a suitable backing, separate structure or another surface specified by the design.
Installation Preparation
Before manufacture and installation, lettering dimensions, available space, power supply position and fixing method must be defined.
For more complex lettering, particular consideration is given to lighting segment layout, cable passages and access to electrical components.
LED Neon Sign Maintenance
Maintenance involves checking lighting profiles, fixings, electrical connections and power supplies.
Cleaning uses appropriate products and procedures according to the installed materials' specifications.
Professional servicing is recommended for electrical repairs or component replacement.
LED Neon Sign and Lettering Prices
The manufacturing price of an LED neon sign depends on dimensions, illuminated outline length and complexity, selected material, light colour, backing type and installation method.
Simpler lettering with fewer lighting segments can require fewer manufacturing operations than complex logos with numerous curves and fine details.
A smaller but more complex sign is therefore not always less expensive than a larger, simpler one.
Factors Affecting Manufacturing Costs
- Total illuminated line length: affects the quantity of LED neon material.
- Shape complexity: the number of curves, angles, breaks and individual elements affects production time.
- LED neon type: profile dimensions, colour, electrical and lighting characteristics affect material cost.
- Backing: material, colour, shape and fixing method affect manufacturing costs.
- Power supplies and controls: suitable electrical components and any lighting control systems form part of the calculation.
- Installation method: location, access and installation complexity affect the total price.
Traditional neon signs have different manufacturing and costing methods. The price depends on the number and length of glass tubes, bending complexity, required power system and installation method.
An accurate price is determined for the specific project from the supplied lettering or logo, dimensions and technical requirements.
