TīmeklisFor this purpose, the electroluminescence spectra are recorded, and the current efficiency (measured in cd/A) and the external quantum efficiency (EQE, measured in percent) are calculated as a function of luminance, assuming Lambertian emission characteristics, from current-voltage-luminance characteristics (IUL characteristics), … TīmeklisTemplate:Merge Template:Seealso Lambert's cosine law says that the total radiant power observed from a "Lambertian" surface is directly proportional to the cosine of the angle θ between the observer's line of sight and the surface normal. The law is also known as the cosine emission law or Lambert's emission law. It is named after …

TīmeklisSome of them have a light output with essentially Lambertian characteristics, while others substantially differ from that, e.g. exhibiting a bell-shaped relatively narrow scattering distribution. Optical diffusers can have different geometrical shapes, adapted to different applications. For example, there are diffuser plates, normally either ...

Tīmeklis2024. gada 24. okt. · Lambertian scatterers and radiators.
