Objective of the work is to design and manufacture experimental models of PLLS with combined electroluminescence and conduct their tests. Research methods - modern methods of research of photoelectric, electrotechnical and statistical parameters and characteristics of the made experimental samples were used in work, development and optimization of designs is executed by methods of computer modeling. The experimental PLLS samples with combined living and cooling of light sources on the basis of a BHTD were made and their parameters and characteristics were tested. The PLLS prototypes ensured luminous flux of at least 20,000 lm, color rendering index over 90 and demonstrated the possibility of power supply from renewable energy sources up to 100% under favorable conditions for generating solar cells. The developed and created experimental models of systems of cooling of powerful light-emitting diodes on the basis of BHTD ensures working temperature conditions of LED crystals (80 - 90 оС) with power over 200 W.
