Guida alla selezione della piastra del diffusore a LED: tipi, materiali e applicazioni

As a professional LED diffuser plate manufacturer, we understand how critical material selection is for achieving optimal lighting performance. Whether you’re designing for LED panels, led light boxes, or TV/Laptop backlight display , choosing the right diffuser plate affects brightness, uniformity, and overall visual comfort. This guide covers the most important considerations when selecting diffuser sheets, including transmittance, haze, and material properties.

1. Is Higher Light Transmittance Always Better?

Many customers assume that the higher the transmittance, the better the lighting effect. However, that’s not always true. A good diffuser plate must balance light transmittance with diffusion capability to avoid visible LED dots and glare.

We offer a wide range of materials including:

Acrylic light diffuser plates (PMMA), which offer high transmittance (up to 95%) and excellent optical clarity.

PC diffuser sheets, which combine 80–88% light transmittance with superior diffusion performance.

PS diffuser plates, which have moderate transmittance (~70%) and are more suitable for basic lighting where cost is a priority.

The ideal solution depends on your specific application. We help our clients select the appropriate diffuser sheet by balancing brightness, light uniformity, and visual comfort.

2. Our PC Diffuser Plate: Features and Testing Methods

Polycarbonate (PC) is one of our most popular materials for Fogli di diffusore ottico, valued for its strength, heat resistance, and light-scattering ability.

We test every PC diffuser plate in-house using precision spectrophotometers to evaluate:

Total light transmittance rate

Haze levels

Impact resistance

These data points are critical to ensuring high performance across commercial lighting, industrial luminaires, and custom LED systems. We supply detailed technical datasheets with each product to support engineering, testing, and production planning.

3. PS Diffuser Plates: Haze and Light Transmission Explained

For applications that prioritize cost-effectiveness and diffusion, our PS diffuser plates are a smart choice. They offer:

Higher haze, which improves light diffusion

Lower transmittance rate compared to PC and acrylic

A lightweight, easy-to-process profile

However, PS materials are more sensitive to heat and UV exposure. We recommend them for indoor applications such as promotional displays and cost-conscious lighting systems.

Understanding the trade-off between haze and brightness is key. We help you choose the right foglio di diffusore ottico by providing performance metrics and material guidance tailored to your needs.

4. Material Comparison and Application Guidance

We provide various diffuser sheet materials to suit a wide range of lighting environments. Here’s a general guide to help you match each type to your application:

Whether you’re sourcing a PC diffuser sheet, an acrylic light diffuser plate, or a cost-efficient PS panel, we provide expert recommendations based on optical data and design requirements.
