Your library or personal account may give you access

Abstract

A new method of creating a source model of a phosphor-converted white LED is demonstrated. It is based on a simple phosphor model, of which some key parameters have been obtained from measuring the near-field chromatic and luminance characteristics of the complete LEDs. The accuracy of the model is verified by measurements and simulations on an LED with a ball lens as primary optics.
