A Near-field Goniospectroradiometer for LED Measurements
ABSTRACT Designing micro-optics for light-emitting diodes must take into account the near-field radiance and relative spectral power distributions of the emitting LED die surfaces. We present the design and application of a near-field goniospectroradiometer for this purpose. Keywords: Near-field photometry, goniophotometer, LED measurement, spectroradiometer 1. INTRODUCTION One of the often-touted advantages of high-flux light-emitting diodes (LEDs) [...]
