scope:

This Technical Report provides guidance to controlgear/integrated lamp designers for the manufacture of products suitable to operate with phase-cut dimmers. It describes the possible voltage signals and the expected behavior of the controlgear/integrated lamps. This document describes expected behavior for controlgear during all operation states of a lighting system. Complete understanding of the requirements should be determined in consultation of this Technical Report for phase cut dimmers. It 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 controlgears. . Safety requirements are not covered by this document, but by respective product standards.
