Bogdanov Svetlana-Optoelectronics Company Group, St.-Petersburg E-mail: avramenko@soptel.ru ABSTRACT Checking product parameters and quality is an important component of the manufacturing process. <...> It intends to reveal defects in fi nished products and to check their reliability during the production process. <...> The purpose of this article is to familiarise a broad range of specialists with the experience of Svetlana-Optoelectronics Company Group in the product check process for light emitting diodes and their compound lighting products, and with its ideas and proposals on the product quality control and quality confi rmation. <...> Keywords: light emitting diodes, light-emitting diode industry, check of parameters, quality control, concept, goniophotometer, production localization 1 Svetlana-Optoelectronics CG is one of the oldest (established in 1998) and largest enterprise associations of the domestic light-emitting diode industry in Russia. <...> It is one of very few domestic industrial groups implementing a full work cycle of light-emitting diode manufacture, including production of light-emitting crystals, LEDs themselves, as well as assemblage of a wide spectrum of lighting devices (LD) with different functions. <...> A conceptual moment of the CG’s activity is a large-scale manufacture of a wide range of light emitting diodes (LED): from half-watt LEDs to mul1 Adapted from materials of a report at the 8th Moscow International Conference “LED FORUM” 12.11.2014, Moscow. 49 ticrystal LED matrices of 100 W power. <...> All types of LED are intended for the most effective illumination functioning in each LD type. <...> Therefore, the variety of LEDs produced, allows for the creation of a wide range of LD products for both general and special purposes. <...> As the result, Svetlana-Optoelectronics CG meets the needs of a wide range of partners: Russian Railways Open Society, State Corporation “Rosatom”, Inter Russian Open Society, the Ministry of Education and Science of the Russian Federation, etc. <...> In cooperation with them, the comprehensive introduction of energy-effective illumination systems using light emitting diodes (LEDIL) are taking place2. <...> Therefore, the reliability <...>
