Abstract

Przedmiotem zgłoszenia jest sposób pomiaru luminancji otoczenia oraz urządzenie do pomiaru luminancji otoczenia. Urządzenie do pomiaru luminancji otoczenia charakteryzuje się tym, że posiada sferyczny element optyczny (1), przy czym w jego wnętrzu znajduje się półsferyczna soczewka (2) zbierająca promieniowanie świetlne z całej przestrzeni sferycznego elementu optycznego, zlokalizowana na początku światłowodu (3), przy czym światłowód jest podłączony do skorygowanego widmowo fotoodbiornika (4), zaś fotoodbiornik (4) jest podłączony do pomiarowego układu mikroprocesorowego (6), który mierzy wartość fotoprądu i jest zlokalizowany w obudowie (5), przy czym do obudowy podłączony jest wężyk spustowy (7) wyzwalający pomiar oraz wyświetlacz wyniku pomiaru (8) i posiada własne zasilanie umieszczone w obudowie (5).The subject of the application is a method of measuring ambient luminance and a device for measuring ambient luminance. The device for measuring ambient luminance is characterized in that it has a spherical optical element (1), wherein inside it there is a hemispherical lens (2) collecting light radiation from the entire space of the spherical optical element, located at the beginning of the optical fiber (3), wherein the optical fiber is connected to a spectrally corrected photoreceiver (4), and the photoreceiver (4) is connected to a measuring microprocessor system (6), which measures the value of the photocurrent and is located in the housing (5), wherein a trigger hose (7) is connected to the housing to trigger the measurement and a display of the measurement result (8) and has its own power supply located in the housing (5).
