WG-Condor: Introduction

Task: Develop a specification for a “Smart interface between indoor luminaires and sensing/communication nodes” → Book 20

Setup:

 40 Subscribers of e-mail reflector ( 20 companies)  10 to 20 active experts

Timeline:

Until Jan. 2018: Collection of ideas, proposals, use cases, some details April 2018: Installation of WG-Condor, book writing started Until now: 8 face-to-face meetings, several Conference Calls, 14 drafts of the book, improving from draft to draft. Q1 / 2020: Completion expected, incl. IPR-review

Zhaga book 20:

Book 20 defines a smart interface between an indoor LED luminaire and a sensing/communication node. The node connects to the LED driver and control system, and typically can provide sensory inputs or enable communication between network components. Nodes can be installed and replaced in the field. Key benefits are provided for

Luminaire makers, as certified sensors from multiple suppliers are available

with a range of different functions

Installers, as certification on interoperability of components exists
End-users, as the luminaire can be adapted with nodes for different

functions, like air quality, presence detection, light levels etc.

Zhaga book 20 specifies requirements for the interface between a luminaire and one sensor/RF-device (LEX-M): Mechanical interface: Standardized openings („holes“) and keep-out volumes in luminaires plus

max. outlines of LEX-M‘s

(4 different sizes) plus Connecting system

Wire-to-wire Wire-to-board

Flat area Mounting plate thickness (min/max) Demarcation LEX-S (min/max)

LEX-LP LEX-MR LEX-LP LEX-MR

Bus Power:

→ DiiA specification DALI-parts 250, 351

Electrical interface

Bus Communication:

→ DiiA specifications DALI-parts 101, 103 and 251, 252, 253, 351

Luminaire Requirements:

→ On top of DiiA specifications, Zhaga specifies requirements for luminaires that enable „plug & play“ for different use cases

Recommendations for system-level:

→ Zhaga gives guidance how „plug & play“ can be achieved

DiiA is responsible for certification of components, Zhaga is responsible for the certification of luminaires. Certification allows to mark luminaires and LEX-M‘s with: Compliance checks: All mechanical aspects: Compliance with Zhaga books (LEX-R / LEX-M; LEX-S / LEX-MR / LEX-LP) confirmed by test houses All electrical & communication aspects: Compliance is given when components are listed in the DiiA database:

Drivers: listed as D4i devices or as DALI-2 devices incl. DALI parts 251-253
LEX-M‘s: listed as D4i devices when complying with DALI part 351
Separate DALI BPS: listed when complying with IEC 62386-101

Planned Certification of products:

Communication is specified by DiiA and listed in the following specifications: DALI part 250 (Power supply): → Characteristics of a DALI bus power supply integrated in a control gear DALI part 251 (MB#1 extension): → Extension to memory bank 1 to enable asset management functionality (luminaire data, e.g. light output, color, date of manufacture) DALI part 252 (Energy reporting): → Information related to energy reporting (e.g. active energy & power of luminaire, load side energy & power) DALI part 253 (Diagnostics & Maintenance): → Information related to diagnostics and maintenance information (e.g. control gear diagnostics and maintenance like operating time, number of shutdowns) DALI part AUX (Aux power supply): → Requirements for an auxiliary (AUX) power supply that can be used to powera load if the power provided by the DALI bus is not sufficient
