The developed method of testing light-emitting diode light sources of various types is discussed in the paper. The practical part is based on the standardization and mathematical modeling of the characteristics of LED radiation sources. The verification of the developed method is carried out by comparing the results obtained with the data of the leading national and international laboratories. The parameters of LED lamps used in two modes of operation are studied: the first mode is daylighting (the spectral characteristics of light stimulate the production of cortisol in the human body and improve its cognitive abilities, productivity and concentration) and the second mode is evening lighting (the spectral characteristics of light do not suppress the production of melatonin, and the human body naturally prepares for rest and sleep). The transition between two modes of operation is performed automatically with the help of a key or a remote control. The results of measurements of LED lamps correspond to the standards, so there is the possibility of using them in serial production. The method used in the work, which meets the requirements of CIE standardization, will allow to predict the spectral characteristics of LED radiation sources, indicate the order of LED failure with increasing ambient temperature. The practical part is based on the standardization and the reduction to practice of the theory of measurement of LED radiation and mathematical modeling methods. The purpose of further research is to develop methods for studying the thermal parameters of LEDs and LED lamps on their basis, which involves the development of a mathematical model for thermal processes in LEDs. |
