Abstract
The paper presents the results of investigating the regularities and mutual influence of electrical and thermal parameters on the photometric characteristics of LEDs integrated into the construction of a miniature lighting device. The experimental procedure for conducting experiments and obtaining measurement information about changes in the photometric and spectral characteristics of LED emissions based on electrical and temperature conditions is described. Additionally, research was conducted on the spectral composition of the lighting device, which includes the studied LED. The observed results confirm the hypothesis of deviations in the characteristics of LEDs within the lighting device depending on changes in operating modes. Through the analysis of obtained dependencies, changes in radiant power and the amount of power dissipated as heat were determined. A methodology has been developed to adjust the parameters (electrical and thermal) of LEDs and determine the operating modes of the light source as a whole to create an energy-efficient LED light source.
