Haze in acrylic diffuser sheet refers to the percentage of light that is scattered when it passes through the material. In LED lighting, haze helps soften direct light, hide LED dots and improve visual uniformity. A low-haze sheet may look brighter, but LED points can become visible. A high-haze sheet can reduce hotspots, but it may lower overall light output.
ASTM D1003 is commonly used to measure haze and luminous transmittance of transparent plastic materials. Clear PMMA can reach about 92% light transmission, while diffuser-grade acrylic is adjusted through formula and surface design to create the right balance between brightness and diffusion.
| Haze Level | Lighting Result |
|---|---|
| Low haze | Higher brightness, weaker LED hiding |
| Medium haze | Balanced brightness and diffusion |
| High haze | Better hotspot control, lower brightness |
| Unstable haze | Batch difference and uneven panel appearance |
A trader may only offer standard Acrylic Diffuser Sheet from available stock, but haze control requires material formula and production adjustment. A manufacturer can match haze, light transmittance, thickness, surface texture and cutting size according to the LED panel structure.
KUNXIN manufactures Optical Plastic materials for LED lighting, including acrylic diffuser sheet, PC diffuser sheet, anti-glare diffuser sheet, Prismatic Diffuser Sheet and Light Guide Plate. Our team can review LED spacing, panel depth, wattage and target brightness before sample development.
A reliable OEM / ODM process should begin with lighting structure analysis. Buyers need to confirm LED pitch, panel depth, diffuser distance, target lumen output, target haze and transmittance range. Sample testing should compare LED hiding, glare control, brightness loss, color tone and light uniformity.
For bulk supply considerations, the project sourcing checklist should include haze tolerance, transmittance range, sheet thickness, flatness, surface defects, protective film, packaging strength and export documents. These details help reduce visible dots and batch inconsistency in repeated orders.
During manufacturing, KUNXIN controls raw material selection, formula mixing, extrusion stability, surface condition, thickness measurement, optical testing and final inspection. Quality checkpoints include haze, luminous transmittance, size accuracy, surface cleanliness, flatness and batch consistency.
For export market compliance, stable material documents, clear batch labels and strong packaging help support projects in Europe, North America and other overseas lighting markets.
Haze is not simply “more is better.” The right Acrylic Diffuser Sheet should match haze with light transmittance, LED layout and fixture depth. For stable LED lighting projects, working with an optical plastic manufacturer helps control both sample performance and bulk supply consistency.
