Choosing the right diffuser type for your LED aluminum profile based on light distribution needs and aesthetic preferences.
The diffuser (or cover) of an LED profile significantly affects light quality and appearance.
Frosted/opal diffusers provide the most even light distribution, eliminating visible LED dots and creating a smooth light line.
Clear diffusers maximize light output but show individual LED dots.
Micro-prismatic diffusers offer a balance between even distribution and light output.
The diffuser material is typically PC (polycarbonate) or PMMA (acrylic).
PC offers better impact resistance and heat tolerance, while PMMA provides better optical clarity and UV resistance..
