1 Scope
This part of IEC 62386 specifies a bus system for control by digital signals of electronic ligthing equipment which is in line with the requirements of IEC 61 347 (all parts), with the addition of DC supplies. This document is only applicable to IEC 62386-1 02:201 4 and IEC 62386-1 02:201 4/AMD1 :— control gear associated with LED modules. NOTE Requirements for testing individual products during production are not included.
9.3 Dimming curve
9.3.1 General Control gear implementing this document may implement IEC 62386-21 8. Depending on the application a choice needs to be made to use control gear that implements IEC 62386-21 8 or not. Implementing IEC 62386-21 8 offers a clearly defined behaviour whenever dimming curves are changed. Unexpected behaviour is avoided, even when changing dimming curves during the application. If the application sets the dimming curve only once, before any further configuration takes place, a simpler version as described in 9.3.3 can be applied. However, there are no guarantees as to how the light level reacts in the case of switching the dimming curve, nor how the stored variables are affected. In this case, the application needs to take care of the configuration of the control gear, including but not limited to setting “minLevel” and/or “maxLevel”..3.2 Dimming curve when IEC 62386-21 8 is implemented Upon accepting the instruction “SELECT DIMMING CURVE (DTR0)” according to this document, the control gear shall behave as if it accepted “SELECT DIMMING CURVE (DTR0)” as defined in IEC 62386-21 8. Upon accepting the query “QUERY DIMMING CURVE” according to this document, the control gear shall behave as if it accepted “QUERY DIMMING CURVE” as defined in IEC 62386-21 8. 9.3.3 Dimming curve when IEC 62386-21 8 is not implemented The dimming curve defined in this document can be set using “SELECT DIMMING CURVE (DTR0)” and can be queried using “QUERY DIMMING CURVE”.If the linear dimming curve is selected, the light output shall be a linear function of the light level as defined in IEC 62386-21 8:201 8, 9.2. When the dimming curve is changed, the physical minimum level (PHM) shall also be adjusted to correspond to the physical minimum light output, which shall not be affected by the choice of dimming curve. If PHM changes due to a change of the dimming curve, the following condition shall be satisfied:Variables that have a range of validity depending on “minLevel” or “maxLevel” shall be adjusted to comply with their given range of validity. Other variables that do not have a range of validity depending on “minLevel” or “maxLevel” shall not change. 9.4 Load deviation Detection of load increase and decrease is an optional feature. If the feature is supported, both bit 2 and bit 3 of “features” shall be set to TRUE (see 9.6) and IEC 62386-21 6 shall be implemented. Upon accepting the query “QUERY LOAD DECREASE” according to this document, the control gear shall behave as if it accepted “QUERY LOAD DEVIATION” as defined in IEC 62386-21 6. Upon accepting the query “QUERY LOAD INCREASE” according to this document, the control gear shall behave as if it accepted “QUERY LOAD DEVIATION” as defined in IEC 62386-21 6. Upon accepting the instruction “REFERENCE SYSTEM POWER” according to this document, the control gear shall behave as if it accepted “REFERENCE SYSTEM POWER” as defined in IEC 62386-21 6.Upon accepting the query “QUERY REFERENCE RUNNING” according to this document, the control gear shall behave as if it accepted “QUERY REFERENCE RUNNING” as defined in IEC 62386-21 6. Upon accepting the query “QUERY REFERENCE MEASUREMENT FAILED” according to this document, the control gear shall behave as if it accepted “QUERY REFERENCE MEASUREMENT FAILED” as defined in IEC 62386-21 6.
