Full title and description

IEC 62386-104:2019/AMD1:2023 — Amendment 1 to "Digital addressable lighting interface (DALI) — Part 104: General requirements — Wireless and alternative wired system components". This 2023 amendment updates Part 104 to include additional requirements and packaging rules for wireless and alternative wired transports used to carry DALI transactions (consolidated as IEC 62386-104:2019+AMD1:2023).

Abstract

This amendment adds and clarifies general requirements for system components that implement DALI functionality when the underlying transport is wireless or an alternative wired medium rather than the conventional wired DALI bus. It provides architecture-level rules, telecommunication unit behaviour, and specific transport packaging (notably support for Bluetooth® Mesh and other transports) to ensure interoperable implementations across different physical transports.

General information

• Status: Amendment incorporated into consolidated publication IEC 62386-104:2019+AMD1:2023 — active standard (amendment published/implemented).
• Publication date: 13 December 2023 (IEC amendment publication).
• Publisher: International Electrotechnical Commission (IEC).
• ICS / categories: 29.140.50 (Lighting installation systems); 29.140.99 (Other standards related to lamps).
• Edition / version: Edition 1.0 — Amendment 1 (2023) incorporated into the 2019 Part 104 text (consolidated version).
• Number of pages: 6 pages (amendment document).

Scope

Applies to DALI system components and the rules for carrying DALI transactions over wireless links and alternative wired transports. The amendment covers system structure and architecture, telecommunication units, message packaging and opcodes for specific transports, addressing/versioning behaviour, and conditions for interoperability with conventional wired DALI subsystems and gateways. It explicitly accommodates multiple transport choices (for example Bluetooth® Mesh and other wireless or alternative wired solutions) as valid underlying telecommunication channels for DALI transactions.

Key topics and requirements

• Definition of telecommunication unit roles, relationships between controllers, input devices and control gear when using non‑DALI transports.
• Message packaging and transaction rules for selected transports — including provisions for embedding DALI transactions inside Bluetooth® Mesh messages (specific model and opcode conventions introduced by the amendment).
• Support for multiple transport options (examples cited in preparatory documents: Bluetooth® Mesh, VEmesh, distributed PLC bus, UDP/IP) and rules to preserve DALI semantics across them.
• Interoperability and gateway behaviour to allow hybrid networks (mixing wired DALI segments and wireless/alternative‑wired segments).
• Requirements for version numbering, addressing, message length handling, and recommendations to limit fragmentation/segmentation for constrained transports.
• National/adoption considerations — amendment intended for adoption as national variants (EN/IEC adoptions appeared in 2024).

Typical use and users

Used by lighting equipment manufacturers, luminaire designers, control‑gear and module vendors, wireless module vendors, system integrators, test and certification laboratories, specifiers and consulting engineers who design or validate DALI-compatible lighting systems using wireless or alternative wired transports. Procurement and compliance teams reference this amendment when specifying interoperable DALI solutions that use Bluetooth® Mesh or other non‑traditional transports.

FAQ

Q: What is this standard?

A: IEC 62386-104:2019/AMD1:2023 is Amendment 1 (2023) to Part 104 of the IEC 62386 DALI series; it updates the general requirements for DALI system components when the underlying transport is wireless or an alternative wired medium.

Q: What does it cover?

A: It covers architecture and behaviour requirements for telecommunication units and system components, rules for packaging and transporting DALI transactions over non‑DALI physical transports (including Bluetooth® Mesh and other transports), addressing/version rules, and guidance for interoperability and gatewaying between wired and wireless segments.

Q: Who typically uses it?

A: Manufacturers of luminaires and control gear, wireless module vendors, system integrators, certification bodies, test laboratories, and specifiers who need to implement or verify DALI functionality over wireless or alternative wired networks.

Q: Is it current or superseded?

A: This document is an amendment published in December 2023 and incorporated into the consolidated IEC 62386-104:2019+AMD1:2023 edition; it is currently the applicable amendment (consolidated text) with stability information shown by IEC. National adoptions (EN/IEC A1:2024) followed in 2024.

Q: Is it part of a series?

A: Yes — it is Part 104 of the IEC 62386 series (Digital Addressable Lighting Interface), which contains many parts (for example 101, 102, 103 and multiple device‑specific and system parts). The amendment updates Part 104 within that series.

Q: What are the key keywords?

A: DALI, Digital Addressable Lighting Interface, wireless, Bluetooth Mesh, alternative wired, telecommunication unit, interoperability, IEC 62386-104, amendment 2023.
