RESEARCH TESTS OF LED LIGHT SOURCES
Annotation
Results of reliability tests of LED lamps are presented. The most critical reasons affecting decrease in light flux from LED light source are identified. The main types and causes of failures of elements of LED lamps electromechanical system are considered. The existing test methods and tools for determining the service life of a LED light source are described. The heating and cooling curves of the LED lamp at the hot spot are experimentally obtained. A graph of change in level of the black box illumination by a LED lamp depending on the number of cycles of its switching on and off is presented.
