INFLUENCE DIMING OF LED LAMPS TO ELECTRICAL PARAMETERS

Abstract

Abstract
Lighting systems are currently one of the main uses of electricity. The most popular option for reducing of
electricity consumption is the use of dimming. Dimming is a type of regulation in which we can regulate luminous
flux of a lamps and luminaires. This system of regulation is used in the road lighting industry, but also in
households. Dimming allows adaptation of the lighting system according to specific requirements and various
ambient conditions such as traffic density, daylight, etc. The regulation of the luminous flux de-pending on the
dimming system can affect the electrical parameters of the luminaires such as the power factor. The article deals
with the electrical parameters of luminaires with various lamps at different types of dimming.
