Дослідження теплових та електрооптичних (електричних, світлових та спектральних) параметрів і характеристик потужного світлодіодного освітлювального пристрою Head Nikolaienko Yurii Ye., Доктор технічних наук Registration Date 04-12-2025 Organization National Technical University of Ukraine «Igor Sikorsky Kyiv Polytechnic Institute» popup.description1 The purpose of the project is to develop and manufacture an experimental model of a high-power LED device with a new highly efficient cooling system for LED light sources based on two-phase technologies, designed to illuminate emergency response areas, as well as to protect and patrol the border of Ukraine and areas close to the combat line, and, in particular, which can be used to equip special military equipment. popup.description2 The design of two-phase heat transfer devices as the copper thermosyphons with a heat transfer intensifier in the evaporation zone and n-pentane coolant has been implemented, which ensures stable operation of a high power LED lighting device at the ambient temperature range from -30°C to +40°C. A silent passive cooling system for natural convection based on an aluminum heat sink profile and built-in 8 copper thermosyphons has been developed to ensure manufacturability, relative cheapness and reliability. The cooling system provides heat dissipation by natural convection not less than 400 W at a maximum temperature on the on the heater case of +100 °C and an ambient temperature of +40 °C, which allowed more than twice the power of the LED lighting device compared to analogues. As a result: a high-power LED lighting device was developed, manufactured and tested based on high power LED COB modules from Citizen (Japan) and the proposed passive cooling system, which made it possible to obtain a luminous flux of more than 61,000 Lm at an electric power of 521 W. The proposed LED lighting device can be used for the rescue works in the emergency zone and advanced equipment for patrolling territories. The project corresponds to the priority direction of science and technology development "National security and defence". Product Description popup.authors Alekseik Yevheniy Serhiyovych Dmytro V.
