The global interlaboratory comparison (IC 2017) on measurements of solid-state lighting (SSL) products with goniophotometers was conducted under the International Energy Agency 4E Solid State Lighting Annex with 36 participating laboratories from 19 countries with a total of 42 goniophotometric instruments including mirror-type, near-field type and source-rotating type goniophotometers. A narrow-beam LED lamp and three different types of LED luminaires, including a street lighting luminaire, were used as comparison artefacts for measurements of 16 different quantities. These included electrical, photometric, and colorimetric quantities, and goniophotometric quantities such as centre beam intensity, beam angle, partial flux (15° cone angle), and angular colour uniformity. CIE S 025 was used as the test method. The results demonstrated overall good agreement on luminous flux and colour quantities, however, larger variations and various problems were identified in goniophotometric quantity results. Near-field type and source-rotating type goniophotometers showed equivalent accuracies overall to those of far-field mirror type goniophotometers.

Photon Localization

Starting from the Riemann-Silberstein formulation of classical electrodynamics the Schrödinger equation for the photon energy wave function is discussed. Hereafter, a propagator description of the space-time emission of a polychromatic photon from an atom is presented, paying particular attention to the near-field electrodynamics. When the atom is embedded in a solid-state plasma the photon emission process can be dramatically modified. Limiting the analyses to solid-state plasmas exhibiting translational and rotational symmetry, the near-field atom-photon-plasma interaction is studied paying particular attention to the plasmariton and plasmon excitation processes. It is shown that the transverse and longitudinal parts of the plasma-screened field propagator link in a direct manner to the free-photon propagator and the longitudinal near-field photon propagator. The necessity of keeping both the transverse and longitudinal parts of the plasma screening in a rigorous description of near-field electrodynamics is demonstrated.
