How to Use Beam Angle Reference for LED Light Boxes

Building light boxes is not always as straightforward as you would like it to be. Due to the varying dimensions, it could be tricky to determine the proper LED light placement to achieve a consistent and uniform light distribution.

The usual challenges in creating light boxes include uneven light delivery across surfaces, hot spots, and glares. 

If you are working on a light box project, you may want to check the beam angle reference to help address this dilemma. You can also contact our team so we can guide you in choosing the right LED lights for your project.  

What is a Beam Angle? 

Beam angle is the measurement of light distribution from the source to the surface or the area being illuminated. This is often quantified in degrees. The narrower the angle of measurement means a more concentrated light distribution, and the wider the angle of measurement equates to a bigger surface area of coverage. The wider beam angle also tends to provide general soft light compared to the narrow angle, which emits focused lighting. 

How do You Use Beam Angle Measurement in LED Light Boxes? 

LED modules are the most popular options for light boxes and illuminated signage due to their flexibility, i.e., they come in a variety of shapes, sizes and colours. LED modules are also durable, bright, energy efficient and require less maintenance.  

Do note that for light boxes, the depth or width of the box matters, and is essential to determine even surface lighting. Placing the light source closer to the surface typically achieves even and smooth lighting as well.  

• 10° to 50° - commonly used for small light boxes. LED lights with beam angles within this range are also applicable for accent lighting, task lighting, displays, channel letters and some decorative lighting. 

• 60° to 170° - applicable for bigger signboards, and light boxes. A wide beam angle, usually between 120° to 160° is advisable to achieve even lighting distribution across the entire surface of the box. LED lights within this range are also applicable for general lighting purposes, both for office and home use.  

Edge-lit vs Back-lit Light Boxes 

You might have come across these two installation options and thought, “which one is better?”  

The answer depends on what type of light box you have, and the range of budget on which you are working. 

Edge-lit, also known as side-lit, as the name implies, is when the light source comes from the edges of the panel. This option tends to work best with thin light boxes. Edge-lit panel usually requires less lighting and takes advantage of light guide plates (reflective material) to disperse light across the surface. Since it uses fewer LED lights, it is the more affordable and eco-friendlier option. Side-lit panels also use less energy and emit less heat.  

On the other hand, back-lit panels are light boxes that are illuminated by LED lights installed at the back of the sign. Back-lit panels generally use more LED lights, which can be costly depending on the size of your light box. This type of LED light installation provides a more consistent lighting distribution, which results in better signage quality.
