Overview

IEC 62386-207:2009 is an international standard developed by the International Electrotechnical Commission (IEC) focusing on the digital addressable lighting interface (DALI). Specifically, Part 207 addresses the particular requirements for control gear associated with LED modules (device type 6). This standard defines protocols and test procedures for electronic control gear that operate on AC or DC supplies. It is meant to be used alongside IEC 62386-101 and IEC 62386-102, which describe general requirements for control gear and control devices.

This standard is essential for manufacturers, designers, and testers working with LED lighting systems to ensure interoperability, performance, and safety in digital lighting control environments. It promotes consistency in how LED modules are digitally controlled within lighting infrastructure.

Key Topics

• Digital Control Protocol: Defines how control gear for LED modules communicates via digital signals within a DALI system.
• Test Procedures: Specifies type test methodologies to verify compliance with requirements; these tests are primarily for product development and certification, not for production line testing.
• Electrical Specifications: Outlines the conditions for operation on AC and DC supplies and describes characteristics necessary for reliable control and communication.
• Transmission Protocol Structure: Describes the structure and timing of messages exchanged between control devices and LED modules.
• Reference Measurement Process: Details the internal procedures that control gear uses to determine actual LED load, a critical step for dynamic and responsive lighting control.
• Load Change Detection: Provides mechanisms by which the system detects significant decreases in LED load, enabling adaptive control and protection.
• Application Extended Command Set: Includes specific command sequences tailored for enhanced functionality and diagnostics, such as querying features, fault detection (thermal overload, short/open circuit), and power referencing.
• Fast Fade Time and Dimming Curves: Defines parameters for dimming behavior and response timing to achieve smooth, predictable lighting effects.

Applications

IEC 62386-207:2009 serves as a technical foundation for:

• Smart Lighting Systems: Integration of LED modules in intelligent lighting control environments with digital communication capabilities.
• LED Control Gear Design: Assists manufacturers in developing products compliant with international standards ensuring compatibility and interoperability.
• Lighting Automation: Supports implementation of adaptive, programmable LED lighting with accurate feedback and fault monitoring.
• Energy Management: Enables precise control and measurement of LED loads, which facilitates energy-efficient lighting solutions.
• Quality Assurance: Provides test methods that manufacturers and third parties can use to verify functionality and safety of LED control gear before market release.
• Building and Infrastructure Lighting: Useful for commercial and residential building installations requiring digital lighting interfaces for LED modules.

Related Standards

• IEC 62386-101:2009 – Digital addressable lighting interface – Part 101: General requirements – System. This standard covers overall system requirements and applies broadly to all DALI compliant lighting products.
• IEC 62386-102:2009 – Digital addressable lighting interface – Part 102: General requirements – Control Gear. It specifies general requirements for control gear types involved in the DALI ecosystem.
• Other parts of the IEC 62386 series cover device types beyond LED modules, enabling a comprehensive framework for all digital lighting control components.

Practical Value

Adherence to IEC 62386-207 ensures LED modules and their control gear can:

• Interface seamlessly with DALI-based lighting control systems.
• Achieve reliable and safe operation under defined electrical conditions.
• Support advanced diagnostic features such as overcurrent protection, thermal shutdown detection, and user-configurable dimming profiles.
• Enable manufacturers to bring products to market with confidence in international compliance and interoperability.
• Facilitate energy efficiency through accurate measurement and adaptive load control.

For engineers, specifiers, and lighting professionals, IEC 62386-207 represents a vital standard for designing, implementing, and testing LED-based lighting solutions aligned with global best practices and emerging smart lighting technologies.

62386-207 © IEC:2009 – 9 –
9.9 Detection of load decrease

If the actual LED load is significantly below the load measured during a successful “reference

measurement”, the gear may switch off the lamp if this is necessary for its safe operation. The

flag bit ‘load decrease’ is to be set.

9.10 Detection of load increase

If the actual LED load is significantly above the load measured during a successful “reference

measurement”, the gear may switch off if this is necessary for its safe operation. The flag bit

‘load increase’ is to be set.
9.11 Current protector
If the actual LED load of the control gear differs by more than a defined amount ΔP from the
load detected during the reference measurement, the current protector becomes active and
switches off the LED.
The current protector shall not become active until there has been a successful reference
measurement.
There are two possible situations in which the current protector becomes active:
– Overload: The actual LED load is higher than the load detected during the reference
measurement by at least ΔP.
– Underload: The actual LED load is lower than the load detected during the reference
measurement by at least ΔP.
The current protector shall become inactive either on mains voltage interruption or on receipt
of a command which causes the arc power level to be 0. If after switching on again, the
situation causing the current protector to become active still remains, the current protector
shall become active again.
The current protector can be enabled and disabled by the commands 225 “ENABLE
CURRENT PROTECTOR” and 226 “DISABLE CURRENT PROTECTOR”.
An active current protector shall become inactive upon reception of command 226 “DISABLE
CURRENT PROTECTOR”.
If the current protector is active, command 224 “REFERENCE SYSTEM POWER” shall be
ignored.
9.12 LED replacement on gear with load increase/decrease or current protector feature
If a LED is replaced with one of a different wattage without a new “REFERENCE SYSTEM
POWER” measurement being performed, the control gear shall detect a load increase or load
decrease as appropriate.
NOTE If a LED is replaced with one of the same wattage, the user should initiate a new ‘REFERENCE SYSTEM
POWER’ measurement only if this is recommended by the manufacturer.
9.13 Fast Fade Time
The Fast Fade Time is used instead of the Fade Time if the Fade Time is equal to 0. The Fast
Fade Time can be set to zero or to any value in the range “Min Fast Fade Time” to 27 as
defined in Table 1.
Programming the Fast Fade Time to 0 means “no fade” (change of light output as quickly as
possible).

The measured power level shall be stored in the persistent memory. Commands received

during the measuring period shall be ignored except query commands and command 256.

After 15 min at most, the control gear shall finish the measurement process and shall go back

to normal operation. The measurement process shall be aborted if command 256

“TERMINATE” is received.
If the current protector is active this command shall be ignored. In this case, bit 7 ‘reference
measurement failed’ in the answer to command 241 “QUERY FAILURE STATUS”, shall be set
and command 249 “QUERY REFERENCE MEASUREMENT FAILED” shall be answered with
“Yes”.
Control gear without this feature shall not react (see command 240).
Command 225: YAAA AAA1 1110 0001 “ENABLE CURRENT PROTECTOR”
Enables the current protector of the control gear. The current protector can become active
after a successful reference measurement started by command 224.
The default configuration of the gear is “current protector enabled”. The status of the current
protector (enabled / disabled) shall be stored in the persistent memory of the control gear.
The current protector is an optional feature. Control gear without this feature shall not react
(see command 240).
Command 226: YAAA AAA1 1110 0010 “DISABLE CURRENT PROTECTOR”
Disables the current protector of the control gear.
The current protector is an optional feature. Control gear without this feature shall not react in
any way. (see command 240).
Command 227: YAAA AAA1 1110 0011 “SELECT DIMMING CURVE”
The dimming curve of the control gear shall be set in accordance with the value of DTR.
DTR = 1 sets the dimming curve to linear. In this case the light output shall be a linear
function of the light level given by any of the arc power control commands in accordance with

the formula
n
X(n) = ⋅100 [%]
DTR = 0 sets the dimming curve to the standard logarithmic output characteristics.
All other values of the DTR are reserved for future needs and shall not change the dimming
curve.
When the dimming curve is changed, the PHYSICAL MINIMUM LEVEL shall also be adjusted
to correspond to the physical minimum light output, which shall not be affected by the choice
of dimming curve.
NOTE 1 There is no requirement for recalculating the programmable arc power levels when changing the dimming
curve.
62386-207 © IEC:2009 – 13 –
NOTE 2 It is recommended that the dimming curve be selected before arc power levels such as scenes, min level,

max level, etc. are programmed.

Command 228: YAAA AAA1 1110 0100 “STORE DTR AS FAST FADE TIME”

If the content of DTR is zero or lies in the range MIN FAST FADE TIME to 27, it shall be

stored as fast fade time. If the content of the DTR is greater than zero but less than MIN

FAST FADE TIME then MIN FAST FADE TIME shall be stored as fast fade time. If the content

of the DTR is greater than 27 then 27 shall be stored as fast fade time.

The control gear uses the fast fade time only if the standard fade time is 0.
