Abstract

LED lighting products are accepted worldwide as primary source of interior and exterior illumination, but issues with quality of light and flicker remain. LEDs lighting products claim higher luminous efficacy and increased energy efficiency compared to incandescent and discharge lamps. In this paper, existing methods to dim LED lighting without flicker are discussed. LED lamp dimming can enhance the experience diners in a hospitality industry, increase productivity in industries and save energy, but correct combination of controls, drivers and LED sources is needed. LED lighting products have evolved from very simple non-dimmable lamps, to sophisticated but costly dimmable lamps, then finally to more economical dimmable lamps. This paper provides a general guidance for selecting a dimming system for a LED lighting product, as well as some realworld examples are discussed on how to use those procedures. The information provided in this paper aims to ensure enhanced dimming performance and to lessen the chance of experiencing compatibility related issues. It must be understood that compatibility does not guarantee enhanced dimming performance like absence of flicker, smoothness of light transition, or a targeted minimum dimming level. Observation best assesses these characteristics; hence mock-ups must be done before final implementation and installation
