(Main)Electrical interface specifications for self ballasted lamps and controlgear in phase-cut dimmed lighting systems
Electrical interface specifications for self ballasted lamps and controlgear in phase-cut dimmed lighting systems
IEC TR 63037:2019 provides guidance to controlgear/integrated lamp designers for the development of products suitable to operate with future phase-cut dimmers. It describes the possible voltage signals and the expected response of the controlgear/integrated lamps. This document describes the expected response of controlgear during all operation states of a phase-cut lighting system and provides a complete understanding of the requirements for phase-cut dimmers. The response of a phase-cut dimmer is described in IEC 60669-2‑1:—, Annex EE. This document specifies the system performance aspects and test procedures for the control by mains voltage phase-cut dimming of the brightness of mains operated electronic lighting equipment intended to be controlled by mains voltage phase-cut dimmers, such as LED integrated lamps and light sources with external controlgear. Safety requirements are not covered by this document, but by respective product standards. This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- emission of audible noise;
- ghosting caused by issues that are not related to the power supply of the dimmer or synchronization;
- stability of phase angle waveform (for the dimmer), including symmetry and stability tests;
- flicker of light loads;
- repetitive ring up voltage;
- dimming range; and
- number of switching cycles have been added.
