Matrycowe pomiary luminancji elektroluminescencyjnych źródeł światła i opraw oświetleniowych -; stan techniki

Abstract: Streszczenie. Matrycowane pomiary rozkładów luminancji cieszą się w drugiej dekadzie XXI wieku dużą popularnością. Niestety, korzystając z cyfrowych metod pomiaru, bardzo rzadko zwracamy uwagę na potencjalne źródła błędów pomiarowych, związane z technologią pomiarów i sprzętem pomiarowym. W artykule przedstawiona zostanie analiza potencjalnych błędów, związanych z wykorzystaniem matrycowych mierników luminancji do pomiarów parametrów niewielkich źródeł światła o skomplikowanym rozkładzie luminancji, jakimi są … Show more

“…For this reason, particular attention should be paid to the accurate registration of the light source luminance distribution, which should cover the ILMD sensor as much (more than 50% of the photosensitive surface) as possible during the measurement. The performed analyses based on the simulation model with respect to the results of lab measurements [2,18] and Fig. 10 clearly show that the proposed simulation method yields very good results.…”

“…The solution to this situation is the use of variable luminance distributions of the light source to read out the luminance value of the light source part which has been hit by the inverse ray, depending on the angle of incidence of this ray on the surface of the mapped LED model. As far as the traditional light sources are concerned, it is proven that in most cases, sufficient accuracy is provided by using the luminance distributions characteristic of measurements with a change of angle of Δγ = 5° [16,18].…”
