Lighting the Way: How Illuminated Signs Work

Illuminated signs serve as a potent asset for businesses, providing heightened visibility, boosting sales, and enticing customers. These signs come alive with light, making them hard to miss, especially during the night or in low light conditions. But how do these illuminated signs work? This blog post will delve into the science and technology behind illuminated signs.

Types of Illuminated Signs

Illuminated signs come in two primary forms: those that are internally lit and those that are externally lit.

Internally lit signs feature a built-in light source, often utilizing LEDs (Light Emitting Diodes). These LEDs are favored for their energy efficiency, long lifespan, and impressive brightness. Emitting light outward, these signs remain visible even in darkness or from afar.

On the contrary, externally lit signs are illuminated by a light source positioned either above or below the sign, creating a striking visual effect. This might be a spotlight, floodlight, or any other external lighting fixture. While not as bright as their internally lit counterparts, externally lit signs offer a unique aesthetic that can be very appealing.

Illumination Techniques

Various illumination techniques are employed to achieve diverse visual effects. For instance, backlit signs make use of a light source, typically LEDs in today's context, positioned behind large color graphics. As the light permeates through the graphics, it creates an enchanting and highly conspicuous glowing effect.

Halo lighting is another widely used technique that involves illuminating individual letters by shining light through their opaque vinyl backings.

Design and Construction

Illuminated signs are typically crafted from robust translucent materials, designed to allow the passage of light. Acrylic and polycarbonate are frequently favored options owing to their exceptional strength and light-transmitting properties.

For internally lit signs, the light source is installed inside the sign casing. If LEDs are used, they're typically arranged in a way that ensures an even distribution of light across the sign's surface.

On the contrary, externally lit signs necessitate precise placement of the external light source to ensure proper illumination of the sign without creating glare or shadows. This meticulous positioning is crucial for achieving optimal visibility and preventing any undesirable visual effects.

Regulations and Considerations

When considering illuminated signage, it is crucial to take into account the specific building and sign regulations in your local area. These regulations may govern factors such as the dimensions, luminosity, and specific type of illuminated signage that is permissible for use.

When selecting a sign, it is important to also take into account the energy efficiency and maintenance needs. LEDs, for example, are a more efficient and durable option compared to traditional incandescent or fluorescent lights.

Illuminated signs are a versatile and effective advertising tool, capable of catching the eye and drawing in customers. Whether you choose an internally lit, backlit, or externally lit sign, understanding how these signs work can help you make an informed decision that best suits your business needs.
