Diffuser Plate

A diffuser plate is an optical sheet used in LED surface lighting and backlighting systems. Its diffusion structure distributes LED light evenly, reducing hot spots and improving overall illumination uniformity. It can be used with light guide plates, custom light panels, and other optical components for commercial lighting, advertising displays, appliance backlighting, and custom optical applications.

Product Information

Introduction

Diffuser plates are made from optical-grade materials with surface or internal diffusion structures that distribute concentrated LED light evenly and improve overall illumination performance.

Compared with diffuser film, diffuser plates offer greater rigidity and structural stability. They can serve as the diffusion layer within an optical system while also providing a degree of structural support.

Different light transmission levels, diffusion properties, thicknesses, and sizes are available to meet various structural and optical requirements.

Diffuser plate selection should consider the LED light source, light guide structure, optical distance, light transmission, and uniformity requirements.

For applications requiring both uniform illumination and structural stability, diffuser plates are often preferred. Material, thickness, and diffusion performance can be selected according to specific project requirements.

We can provide diffuser plate selection, optical matching, and supporting solutions, integrating diffuser plates with light guide plates, reflective materials, and other components to form a complete optical system.
