ОЦІНКА ВІДПОВІДНОСТІ ПАРАМЕТРІВ СВІТЛОДІОДНИХ ДЖЕРЕЛ СВІТЛА ВИМОГАМ НОВИХ РЕГЛАМЕНТІВ КОМІСІЇ ЄС 2019/2020 та ЄС 2019/2015

Abstract

The results of studies of the energy efficiency and functional parameters of non-directional LED lamps for replacing incandescent lamps, which are supplied to Ukraine as aid for reducing electricity costs for lighting in the residential sector, and their compliance with the new requirements of the Commission Regulation (EU) 2019/2020 on establishing requirements are presented to ecodesign for light sources and Commission Delegated Regulation (EU) 2019/2015 on energy labeling of light sources, which entered into force in EU countries in 2021. In Ukraine, national technical regulations are being developed on the basis of these regulations. The following parameters of LED lamps with a power of 5-12 W were measured: power consumption, power factor, useful luminous flux, correlated color temperature, uniformity of color, color rendering index, short-term indicator of light flickering, indicator of the visibility of the stroboscopic effect, coefficient of preservation of luminous flux after 3000 hours of operation of the lamps and others The maximum power allowed by the Regulation was calculated, which is defined as a function of the declared useful luminous flux and the declared color rendering index, as well as energy efficiency classes in accordance with the requirements of the new energy labeling, the service life of the lamps was estimated according to the experimentally determined coefficient of preservation of the luminous flux and according to the data of the service life declared by the manufacturer. It is shown that most of the parameters of LED lamps entering Ukraine meet the requirements of the new Commission (EU) Regulations and despite the identified inconsistencies among individual manufacturers, there have been successes in increasing the energy efficiency and quality of LED lamps over the last decade. Keywords: Commission Regulations (EU), LED light sources, energy efficiency, functional parameters.
