AN OFF/ON AND BRIGHTNESS ADJUSTMENT CONTROL ARRANGEMENT FOR A PHASE CUTTING CONTROL DIMMER AND A METHOD OF OPERATION THEREOF

摘要

An ON/OFF operating state and brightness adjustment control arrangement for a phase cutting control dimmer including a microcontroller that receives and interprets a pulse signal with a characterisation dependent on degree of rotary angular positioning, acceleration and/or time of rotation made by the user when rotating a rotary encoder, wherein the pulse signal assists in defining levels of light brightness for the lamp under the control of the phase cutting control dimmer or changing the ON/OFF operating state of the dimmer.
