Backlit Billboards

Backlit billboards are large outdoor advertising displays that use lighting positioned behind the advertising surface to illuminate the graphics. The lighting can help the advertisement remain visible in low-light conditions and can give colours and images a different appearance after dark. They are suitable for businesses that want their outdoor advertising to remain visible during both daytime and evening hours.

What Are Backlit Billboards?

Backlit billboards are advertising displays illuminated from behind rather than from the front. The advertising graphic is placed over or in front of a light source, allowing the light to pass through the display material and illuminate the printed artwork.

Modern systems commonly use LED lighting because LEDs can provide consistent illumination and are available in different configurations. Older installations may use fluorescent lighting or other lighting systems depending on the structure.

How Do Backlit Billboards Work?

A backlit billboard normally consists of a supporting structure, a translucent advertising face or printed material, and a lighting system positioned behind the advertising surface.

When the lighting is switched on, light spreads across the rear of the advertising face. The translucent material allows the light to illuminate the graphics, making the advertisement easier to see in darker conditions.

The design of the lighting system is important because uneven lighting can create bright and dark areas across the billboard. The size of the display, type of material, distance between the lights and advertising face, and lighting configuration all affect the final result.

Benefits of Backlit Billboards

1. Visibility in Low-Light Conditions

Backlighting allows the advertisement to remain illuminated after dark and during other low-light conditions. This can make the billboard suitable for locations where evening traffic and activity are important.

2. Day and Night Advertising

A backlit billboard can display advertising during the day and continue to provide an illuminated display at night, depending on the operating schedule and lighting system.

3. Illuminated Visual Effect

Lighting from behind the advertising face can create a distinctive appearance, particularly when used with strong colours, photographs, logos and other high-quality graphics.

4. Suitable for High-Visibility Locations

Backlit billboards can be used in commercial areas, shopping environments, major roads and other locations where illuminated advertising is appropriate and permitted.

5. LED Lighting Options

LED technology can be used in many backlit billboard systems. LEDs are available in different brightness levels and configurations, allowing the lighting system to be designed according to the size and requirements of the display.

Types of Backlit Billboard Lighting

The lighting technology used for a backlit billboard can vary depending on the structure and project requirements.

• LED backlighting: A commonly used modern option that can provide consistent illumination with relatively low power consumption.
• Fluorescent lighting: Used in some older or existing illuminated display structures.
• Custom LED systems: Lighting layouts can be designed around the size and construction of a particular billboard.

The appropriate lighting system depends on the billboard structure, advertising material, available power, required brightness, operating hours and maintenance requirements.

Where Are Backlit Billboards Used?

Backlit billboards can be suitable for locations where advertising needs to remain visible during evening hours as well as during the day.

• Major roads and highways
• Commercial areas
• Shopping centres
• Business districts
• Retail developments
• Entertainment areas
• Petrol station environments
• Transport-related locations
• Outdoor advertising sites

The suitability of a location depends on available space, viewing distance, surrounding lighting, traffic conditions, property requirements and applicable outdoor advertising regulations.

Uses of Backlit Billboards

Backlit billboards can be used for a wide range of advertising campaigns.

• Business and corporate branding
• Product advertising
• Retail promotions
• Restaurant and hospitality advertising
• Property developments
• Automotive advertising
• Entertainment and event promotion
• Service-based businesses
• Seasonal campaigns
• Brand awareness campaigns

Designing a Backlit Billboard

Backlit artwork needs to be designed with the lighting system and advertising material in mind. Colours can appear differently when illuminated from behind, so the final artwork should be tested or prepared according to the selected material and printing process.

Important design considerations include:

• Use clear and readable typography.
• Keep the main message simple.
• Use high-quality images suitable for large-format printing.
• Consider how colours will appear when illuminated.
• Allow for the viewing distance of the billboard.
• Place the logo and important information where they are easy to recognise.
• Avoid overcrowding the available advertising space.
• Consider both daytime and nighttime viewing.

Backlit vs Front-Lit Billboards

Backlit billboards use lighting positioned behind the advertising face, while front-lit billboards use lights positioned in front of the advertising surface to illuminate it.

Backlighting can create a more integrated illuminated appearance, while front lighting may be more suitable for certain existing billboard structures. The choice depends on the structure, advertising material, available power, installation requirements and desired appearance.

Are LED Backlit Billboards Energy Efficient?

LED lighting can use less electricity than some older lighting technologies, but actual energy consumption depends on the number of LEDs, brightness, billboard size, operating hours and lighting configuration.

LED systems can also have different maintenance requirements from older lighting technologies. The overall operating cost should therefore be considered together with installation and maintenance requirements.

How Much Do Backlit Billboards Cost?

The cost of a backlit billboard depends on several factors, including the billboard size, structure, lighting system, advertising material, artwork, printing, electrical requirements, installation and maintenance.

A new illuminated billboard may require different equipment and installation work from an existing billboard that is being converted to backlighting. An accurate quotation requires the project specifications and installation location.

Maintenance of Backlit Billboards

Backlit billboards require maintenance of both the advertising face and the lighting system. LED modules, connections, power supplies and other electrical components should be checked when required.

The advertising face should also be inspected for dirt, damage, fading or other issues that may affect the appearance of the display. Regular maintenance can help identify lighting problems before they affect the entire billboard.

Installation Considerations

Installing a backlit billboard requires consideration of the supporting structure, advertising material, lighting position, electrical supply, access for maintenance and environmental conditions.

The lighting should be distributed as evenly as possible across the advertising surface. The billboard must also be securely installed and suitable for the conditions of the selected site.
