Introduction
Internally illuminated signs are powerful tools for communication. Their luminous presence not only enhances visibility but also adds a touch of sophistication to any business or community space. However, achieving the desired impact with these signs requires careful planning and execution. In this article, we’ll look into internally illuminated signs, exploring what they are and common mistakes to avoid for businesses and communities considering their use.
What Are Internally Illuminated Signs
Internally illuminated signs, also known as backlit signs, are a type of signage that uses internal lighting sources to illuminate the sign’s message or graphics. The lighting sources within internally illuminated signs usually include LED modules. LED lighting has become increasingly popular due to its energy efficiency, durability, and versatility in creating dynamic lighting effects.

Mistakes to Avoid With Internally Illuminated Signs
While internally illuminated signs can be highly effective marketing tools, several common mistakes can diminish their impact. Here are 20 mistakes to avoid when designing, installing, or maintaining these signs:
Poor Visibility:
Failing to ensure adequate contrast between the sign’s text or graphics and the background can reduce visibility, especially during daylight hours or in brightly lit environments.
Overly Complex Designs:
Complex designs with excessive detail or small text can be challenging to read, particularly when illuminated. Keep designs simple and focus on key messaging to maximize impact.
Incorrect Sizing:
Choosing the wrong size for your sign relative to its intended viewing distance can result in either unreadable text or a sign that appears disproportionately small.
Inadequate Lighting:
Insufficient lighting within the sign can lead to uneven illumination or dark spots, detracting from the sign’s overall effectiveness. Ensure proper lighting levels for consistent brightness throughout.
Ignoring Local Regulations:
Failing to obtain necessary permits or disregarding local sign regulations can result in fines or forced removal of the sign. Always consult local authorities before installing a new sign.
Neglecting Maintenance:
Lack of regular maintenance can cause lights to burn out, acrylic faces to yellow or crack, and overall deterioration of the sign’s appearance. Implement a maintenance schedule to address issues promptly.
Inconsistent Branding:
Inconsistencies in branding elements such as colors, fonts, or logos can dilute brand recognition and confuse customers. Maintain consistency across all signage to reinforce brand identity.
Poor Placement:
Placing the sign in a location where it is obstructed by trees, buildings, or other objects can significantly reduce its visibility and effectiveness. Choose a strategic location with maximum exposure to the target audience.
Ignoring Energy Efficiency:
Older sign models with inefficient lighting sources can result in higher energy costs and increased environmental impact. Opt for energy-efficient LED lighting to reduce operating expenses and carbon footprint.
Ignoring Surrounding Environment:
Failing to consider the surrounding environment, such as ambient lighting conditions or architectural features, can result in a sign that clashes with its surroundings or fails to stand out effectively.
Inconsistent Illumination:
Variations in lighting intensity or color temperature within the sign can create a disjointed appearance. Use uniform lighting to ensure a cohesive and professional look.
Ignoring Maintenance Accessibility:
Installing the sign in a location that is difficult to access for maintenance purposes can lead to delays in repairs and increased costs. Choose a location that allows for easy access by maintenance personnel.
Using Low-Quality Materials:
Cutting corners on materials such as acrylic, LEDs, or aluminum framing can result in signs that deteriorate quickly or fail to meet durability standards. Invest in high-quality materials for long-lasting performance.
Lack of Contrast:
Insufficient contrast between the sign’s text or graphics and the background can make it difficult for viewers to discern the message, especially from a distance or in low-light conditions. Ensure adequate contrast for readability.
Ignoring Design Principles:
Neglecting fundamental design principles such as balance, hierarchy, and proportion can result in a visually cluttered or unappealing sign. Work with experienced designers to create visually impactful signage that effectively communicates your message.
Underestimating Sign Maintenance Costs:
While the initial cost of installing an internally illuminated sign may seem significant, underestimating ongoing maintenance costs can lead to budgetary strain in the long run. Factor in regular maintenance, including cleaning, bulb replacement, and repairs, when budgeting for your sign project to avoid unexpected expenses down the line.
Neglecting Sign Permits and Zoning Regulations:
Installing an internally illuminated sign without obtaining the necessary permits or complying with local zoning regulations can result in fines, forced removal of the sign, and delays in your signage project. Research and obtain all required permits and approvals before proceeding with sign installation to ensure compliance with local regulations.
Choosing Inappropriate Mounting Methods:
Selecting the wrong mounting method for your internally illuminated sign can compromise its structural integrity and pose safety risks. Consider factors such as wind load, building material compatibility, and installation location when choosing mounting hardware to ensure a secure and stable installation that complies with safety standards.

FAQs (Frequently Asked Questions)
Q1: What are the benefits of using LED lighting in internally illuminated signs?
LED lighting offers several benefits, including energy efficiency, long lifespan, durability, and versatility in creating dynamic lighting effects. LED signs also require less maintenance compared to traditional fluorescent lighting.
Q2: How do I determine the appropriate size for an internally illuminated sign?
The size of the sign should be proportional to its intended viewing distance. As a general rule, aim for one inch of letter height for every 10 feet of viewing distance. However, factors such as the surrounding environment and viewing angle should also be considered.
Q3: Are internally illuminated signs suitable for outdoor use?
Yes, internally illuminated signs can be designed for outdoor use, provided they are constructed using weather-resistant materials and sealed to prevent water intrusion. LED lighting is particularly well-suited for outdoor signs due to its durability and energy efficiency.
Q4: How often should internally illuminated signs be maintained?
Regular maintenance is essential to ensure the continued effectiveness and longevity of internally illuminated signs. Depending on factors such as environmental conditions and usage, maintenance may be required quarterly, semi-annually, or annually.
Q5: Can internally illuminated signs be customized to match my brand’s colors and fonts?
Yes, internally illuminated signs can be fully customized to incorporate your brand’s colors, fonts, logos, and other branding elements. Work with a reputable sign manufacturer or designer to create a custom sign that accurately reflects your brand identity.
Q6: What are the typical lifespan and warranty coverage for internally illuminated signs?
The lifespan of an internally illuminated sign can vary depending on factors such as usage, environmental conditions, and quality of materials. However, LED signs typically have a lifespan of 50,000 to 100,000 hours or more. Warranty coverage varies by manufacturer but typically ranges from one to five years for LED components and structural elements.
Conclusion
Internally illuminated signs offer businesses and communities a powerful means of enhancing visibility, brand recognition, and community identity. By avoiding common mistakes such as poor visibility, inadequate lighting, and inconsistent branding, businesses can maximize the effectiveness of their signage investments. By addressing frequently asked questions and adhering to best practices in design, installation, and maintenance, businesses and communities can harness the full potential of internally illuminated signs to attract customers, convey messages, and leave a lasting impression.
