Abstract
V teoretičnem delu predstavim spektre svetlobe, učinkovitost svetil v fiziološkem merilu, uporabljena svetila in uporabljene senzorje. V eksperimentalnem delu naredim primerjavo uporabljenih senzorjev: spektrometra, ki meri spekter svetila, luksmetra, ki meri osvetljenost v fiziološkem merilu in merilca gostote svetlobnega toka. Najprej poiščem povezave med merjenimi količinami, nato pa izmerke primerjam med sabo. Z umerjenimi senzorji določim izkoristek svetil v fiziološkem merilu. Gre za izkoristek, kot ga zaznajo človeške oči. Za določitev izkoristka izmerim moč svetila, ugotovim kako svetilo svetlobo oddaja v prostor in kolikšen del energije, ki jo troši svetilo, se pretvori v vidno svetlobo. To naredim za klasično žarnico na žarilno nitko, varčno sijalko in zeleno ter belo svetlečo diodo.

Secondary title: |
Measuring of luminous efficacy of light sources |
Secondary abstract: |
In the theoretical part of my thesis, I present light spectra, luminous efficacy, as well as light sources and sensors used in my experimental work. In the experimental part of the thesis, I compare three sensors: a spectrometer measuring the light spectrum, a luxmeter measuring the light intensity, as perceived by the human eye, and a light meter measuring the light intensity in watts per square meter. To compare the sensors, I find the relation between the quantities they measure. With calibrated sensors, I calculate luminous efficacy by measuring power consumption of light sources, the angular distribution of the light, and the amount of the visible light they produce. I use a classic light bulb, an energy-saving light bulb, and green and white light emitting diodes. |
