LED Light Diffuser Sheet Vs. Acrylic Board

Are you confused about the difference between LED light diffuser sheets and acrylic boards? You're not alone! These two materials are often used in similar applications, but they have different properties and functions. In this article, we'll explore the differences between LED light diffuser sheets and acrylics boards and help you determine which one is right for your project.

What is a LED Light Diffuser Sheet?

A LED light diffuser sheet is a type of plastic sheet that is used to diffuse light emitted from a light source. The main function of a LED light diffuser sheet is to soften and distribute light evenly, resulting in a more uniform and pleasing illumination effect. LED light diffuser sheets are commonly used in applications such as liquid crystal displays, imaging display systems, and LED lighting.

How does a LED Light Diffuser Sheet Work?

The basic principle behind a LED light diffuser sheet is the interference of light. When light passes through a smooth interface between two mediums, part of the light is reflected by the interface, and part of the light is refracted in the other medium through the interface. This phenomenon is governed by the laws of reflection and refraction in geometric optics.

The special feature of a LED light diffuser sheet is that it greatly interferes with the light. No matter what the original design's light distribution curve is, as long as the light passes through the diffuser, it will change the beam angle to 160-176 degrees. This means that the light is dispersed in a wider angle, resulting in lower illuminance.

One of the biggest advantages of using a LED light diffuser sheet is that it can help to prevent color deviation. This is because some LEDs generate filters that prevent certain wavelengths from penetrating the diffuser sheet.

What is a LED Light Diffuser Sheet Made of?

LED light diffuser sheets are typically made of polycarbonate (PC), a high-performance plastic that is known for its excellent impact resistance, heat resistance, and optical clarity. PC is an ideal material for LED light diffuser sheets because it has a low refractive index, which means that it interferes less with the light passing through it.

What is an Acrylic Board?

An acrylic board, or polymethyl methacrylate (PMMA) board, is a type of plastic sheet that is commonly used for applications such as signs, displays, and lighting fixtures. Acrylic boards are known for their excellent optical clarity, impact resistance, and weatherability.

How does an Acrylic Board Work?

In terms of its optical properties, an acrylic board is a full-radiation board. This means that when light enters from one end, it basically all comes out from the other end. This makes acrylic boards ideal for applications where you want to maximize the amount of light transmitted through the material, such as signs and displays.

In the case of lighting fixtures, however, acrylic boards need to be modified to disperse the light emitted from the light source. This is typically done by printing dots or other patterns on the surface of the acrylic board, which helps to scatter the light and create a more even illumination effect.

What is an Acrylic Board Made of?

Acrylic boards are typically made of polymethyl methacrylate (PMMA), a high-performance plastic that is known for its optical clarity, impact resistance, and weatherability. PMMA has a higher refractive index than PC, which means that it interferes more with the light passing through it.

LED Light Diffuser Sheet vs. Acrylic Board: Which is Better?

So, which material is better for your application: LED light diffuser sheet or acrylic board? The answer depends on your specific needs and requirements.

If you need to diffuse light emitted from a light source, a LED light diffuser sheet is the better choice. LED light diffuser sheets are specifically designed to scatter light and create a more even illumination effect. They are ideal for applications such as liquid crystal displays, imaging display systems, and LED lighting.

If you need a material that maximizes the amount of light transmitted through it, an acrylic board is the better choice. Acrylic boards are known for their excellent optical clarity and are ideal for applications such as signs and displays where you want to showcase graphics and text.

Conclusion

In summary, LED light diffuser sheets and acrylic boards are two different types of plastic sheets that are used for different applications. LED light diffuser sheets are designed to diffuse light emitted from a light source, while acrylic boards are designed to maximize the amount of light transmitted through them. By understanding the differences between these materials, you can choose the right one for your project and ensure its success.
