Construction and Optimization of Through-Hole LED Models for Use in Designing Traffic Signboards

A modeling procedure was proposed for the through-hole LEDs commonly used in traffic signs. The measurements from a sample batch of LEDs were performed at several midfield distances to provide a set of representative angular intensity distributions as the target pattern in the modeling process. The...
