How Agitators Help Overcome Sedimentation in LED Phosphor Dispensing
By NSW Marketing Team. Last update on February 4, 2025.
What is Sedimentation?
In LED phosphor dispensing, sedimentation can lead to inconsistent quality and inefficiency. Sedimentation refers to the settling of solid particles, like phosphor, within a liquid medium due to gravity. In dispensing systems, this causes heavier phosphor particles to settle at the bottom of the syringe, leading to inconsistent material flow.
Why Does Sedimentation Happen?
Phosphor materials are inherently high in viscosity. Without continuous agitation, particles settle over time, this foundational issue cascades into several other challenges:
1. Colour Mismatches
Cause: Uneven layer thickness results in varying phosphor concentration.
Impact: The inconsistent conversion of blue light causes visible colour discrepancies, compromising LED performance.
2. Production Disruptions
Cause: Settling phosphor particles clog dispensing nozzles.
Impact: Increased maintenance and downtime drive up production costs.
The Solution: NSW Automation’s Agitation Systems
Our agitation systems prevent sedimentation by keeping phosphor materials evenly suspended, ensuring consistent dispensing and reliable production.
