Novosibirsk students revamp LED-based street lightingStudents at Novosibirsk State Technical University in Siberia have developed new ways of effectively removing heat from surface mounting LEDs, especially for street lighting

Students at Novosibirsk State Technical University in Siberia have developed new ways of effectively removing heat from surface mounting LEDs, especially for street lighting, portal Science and Technology RF reported. With an array of LEDs? unique properties, from high efficiency to long service life, to environmental safety, to vibration resistance, etc., the light-emitting diodes can be used in a wide range of sectors, including lighting systems, instruments illumination, advertising, or automotive alarm systems. However, the overheating of LED-based lighting hardware leads to a considerable reduction of a diode?s service life and its luminous flux, thus resulting in a decrease in a system?s reliability. To address the problem, Dmitry Vaiman, an NSTU student, and his team have developed solutions for designing competitive LED casings with improved heat removal. Based on the results of their own study of all important features of modern LEDs manufactured by the world?s leading makers, the young engineers have offered innovative multiple-crystal structures, whole metal substrates and metalized rods as a way out of the predicament...
