DALI simplifies the complex IoT world for luminaire manufacturers



DiiA   is   developing specifications   for   an   optimised   DALI   interface   inside

Luxeon High Power

luminaires, which will simplify the connection of  luminaires  to   IoT   networks.




DiiA,  the  global  DALI  alliance,  is  taking  further  steps  to  bring  the  extensive  benefits  of  DALI  to  the

Internet  of  Things  (IoT).  Having  established  the  DALI-2  certification  process,  which  secures

interoperability  between  DALI  devices,  DiiA  is  developing  new  specifications  that  extend  the  well-

established  DALI  lighting  protocol.  These  will  create  new  possibilities  for  DALI  technology  in  the  IoT

age,  while  making  use  of  DALI’s  strength  as  a  robust,  reliable  and  relatively  low-cost  communication

technology  optimized  for  lighting  applications.


DiiA  is  standardizing  the  way  in  which  DALI  drivers  can  exchange  measurement  and  diagnostic  data

in  a  well-defined  format.  Such  a  standardized  data  model  is  essential  for  DALI  products  to  participate

in  the  IoT  world.  Building  on  this,  DiiA  is  also  seeking  to  simplify  the  connection  of  luminaires  to  the

IoT  via  in-built  communication  nodes.


“DiiA  is  helping  to  simplify  the  complex  IoT  world  for  the  lighting  industry,”  says  Ruud  van  Bokhorst,

General  Manager  of  DiiA.  “Our  new  specifications  will  enable  luminaires  to  connect  to  various  IoT

networks,  while  building  on  proven,  standardized  DALI  technology.”


The  standardized  data  model  will  specify  the  content  and  format  of  measurement  and  diagnostic

data,  as  well  as  the  location  of  the  data  in  the  DALI  driver.  This  will  enable  seamless  data  exchange

between  DALI  products.  For  example,  luminaires  could  provide  power  consumption  data,  allowing

energy  analytics  and  further  improving  servicing  and  maintenance  within  lighting  systems.


Building  on  this  harmonized  data-model,  DiiA  is  also  developing  a  specification  for  DALI  drivers  to

provide  power  to  sensors  and/or  communication  devices  that  are  integrated  into  luminaires.  This

Luxeon High Power

eliminates  the  need  to  provide  mains  power  to  the  communication  or  sensor  nodes,  or  to  use  a

separate  DALI  power  supply.  The  specification  will  simplify  the  creation  of  a  DALI  network  inside  a

luminaire,  and  will  enable  intelligent  lighting  fixtures  that  can  communicate  with  the  IoT  via  DALI-

connected  sensing/communication  nodes.  This  interface  could  also  allow  upgrading  of  luminaires  to

the  latest  IoT  technology.


DiiA  welcomes  all  interested  companies  to  become  members  and  to  participate  in  the  development

of  new  specifications  and  other  DALI-related  programs.

About DiiA

The Digital Illumination Interface Alliance (DiiA) is an open, global consortium of lighting companies that aims to grow the market for lighting-control solutions based on Digital Addressable Lighting Interface (DALI) technology. DiiA was established in response to industry requests for an independently-verified DALI-2 certification program that covers the functionality specified in version 2 of the IEC 62386 family of international standards. DALI-2 certification brings the promise of significantly improved interoperability and additional functionality compared with current DALI systems in the market. DiiA is a member program of the IEEE Industry Standards and Technology Organization (ISTO). For more information, see
