The Functionality of an LED Diffuser

The primary purpose of an LED diffuser is to evenly distribute LED lighting. However, its role extends beyond that. Modern LED diffusers also help regulate colors and enhance the overall design of a space. Let’s delve into why you need an LED diffuser.

Key Functions of LED Diffusers

Here are a few reasons why LED diffusers are essential:

1. Scattering and Spreading Light: LED diffusers excel in scattering and spreading LED light within a given area, creating a more uniform illumination.
2. Eliminating Hot Spots: By using a diffuser, you can effectively eliminate the problem of hot spots caused by direct LED lighting.
3. Creating a Natural Atmosphere: LED diffusers can simulate the soft light of the sun indoors, fostering a natural ambiance and eliminating harsh shadows. Additionally, diffusers can produce soothing light, making them easy on the eyes.

DIY LED Strip Diffuser: Creating Your Own

If you’re interested in making your own LED strip diffuser, here’s a step-by-step guide to help you out.

Step 1 – Calculate the LED Strip Requirements

For the purpose of this guide, we’ll use 5050 LEDs, which are the standard LEDs found on most LED strips. These LEDs measure 5mm x 5mm. Assuming you have 60 LED lights per meter, each LED will be spaced approximately 17mm apart on the strip, with a beam angle of 120 degrees.

Step 2 – Choose the Right Aluminum Extrusions

Select aluminum extrusions that are perfect for housing your LED strips. Opt for extrusions with a flat diffuser screen and a deeper profile. An 11mm depth is ideal, as it is slightly higher than the standard 10mm LED diffuser. However, if you want to position the LED strip farther away from the diffuser with a larger diffuser size, consider a 17mm extrusion.

Step 3 – Calculate the Best Extrusion Size

Now that you have two options – 10mm or 17mm extrusion – consider the following factors:

1. The 10mm extrusion partially overlaps the aluminum cone, with the borders nearly touching the LEDs and diffuser.
2. With the 17mm extrusion, you can have three cones overlapping while maintaining a good amount of space. This results in better light distribution. Therefore, the 17mm extrusion is the superior choice.

Step 4 – Test the Extrusions

To determine which extrusion size distributes your LED light strip more effectively, conduct a test. It’s essential not to assume that the larger 17mm extrusion is always the best choice. Consider factors such as prolonged exposure and overall lighting requirements.

Step 5 – Optimize Light Distribution

If you have established that the 17mm extrusion is the most effective light distributor, there’s still room for improvement. To ensure optimal light distribution, take the light source farther away from the diffuser. By adjusting the angle of the extrusion to around 60 degrees, you can achieve a more uniform lighting effect.

Step 6 – Enhance Diffusion with Wadding

For a double diffusion effect, place wadding material between the diffuser and the LED strip. This simple yet effective technique further enhances the dispersion of LED light.

Frequently Asked Questions about LED Light Diffusers

Here are answers to some commonly asked questions about LED strip diffusers:

Q1: Do LED lights require a diffuser?

A1: Yes, especially if you want to achieve even distribution of LED lighting.

Q2: How can you diffuse LED strip lights?

A2: There are three simple methods:

1. Place an opaque material over the LED light.
2. Apply a semi-transparent covering on top of the LED light.
3. Increase the distance between the diffuser and the LED extrusion.

Q3: Can LED strip lights cause cancer?

A3: No, there have been no reported cases of LED strips causing cancer. LED lighting does not produce UV rays.

Q4: What are the benefits of using an LED strip diffuser?

A4: The benefits of using an LED strip diffuser include:

• Uniform Illumination: Diffusers create a more uniform and consistent light output without noticeable bright spots or dark areas.
• Reduced Glare: Diffusers minimize glare by softening the intensity of the light, making it easier on the eyes.
• Enhanced Aesthetics: Diffused light provides a softer and more pleasant ambiance, enhancing the overall aesthetics of the space.
• Protection: Diffusers protect the LEDs from dust, moisture, and physical damage, ensuring longevity and optimal performance.
• Customization: Some diffusers come in frosted or textured finishes, allowing users to customize the light’s appearance and mood.

Q5: Can LED strip diffusers change the color of the light emitted by the LEDs?

A5: No, LED strip diffusers do not change the color of the light emitted by the LEDs. They only affect the distribution and diffusion of the light. However, some diffusers may have a frosted or colored finish, which can slightly modify the appearance of the light by softening or tinting it.

Conclusion

By now, you have a comprehensive understanding of LED strip diffusers and their importance. These diffusers effectively distribute light evenly, eliminating hot spots caused by LED lights. When planning an LED lighting design, we highly recommend using a diffuser. Furthermore, with the step-by-step guide provided, you can now create your very own LED strip diffuser.
