ASSESSMENT OF THE COMPLIANCE OF THE PARAMETERS OF LED LIGHT

SOURCES WITH THE REQUIREMENTS OF THE NEW EU COMMISSION

REGULATIONS 2019/2020 and EU 2019/2015


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.
