For these uninitiated into the world of lighting trade requirements improvement and the way the varied requirements our bodies work together with each other, it’s honest to say: it’s sophisticated.  There are quite a few nationwide in addition to worldwide our bodies that publish requirements related to lighting and lighting controls, however the organizations mentioned beneath arguably have the largest influence by way of product design and improvement in North America.

Earlier than we start a dialogue of requirements, it’s worthwhile to take a second to debate the framework underneath which most requirements are developed.  The American Nationwide Requirements Institute (ANSI), administers and coordinates requirements improvement within the U.S.  The ANSI improvement course of requires consensus-based content material and strict assessment and balloting procedures.  Lots of the requirements in use by the lighting trade in North America are developed in line with ANSI protocols and as such, embrace an ANSI designation of their titles.

The Nationwide Electrical Code (NEC) is a state and locality-adoptable security normal printed by the Nationwide Fireplace Safety Affiliation as a part of the Nationwide Fireplace Code. As a result of it was developed utilizing ANSI procedures, the formal designation of the NEC is ANSI/NFPA 70.  A change within the 2020 NEC code that took impact at first of this 12 months now not permits use of gray-colored wire insulation for low-voltage lighting management circuit conductors (i.e., 1-10V dimming management).  This transformation was made to assist decrease the chance of confusion and subsequent damage to tools installers (grey is an allowed colour for grounded department circuit conductors). 

In response to this new requirement, the Nationwide Electrical Producer’s Affiliation (NEMA) Cable Part and Lighting Programs Division labored collectively on a advice for a alternative wire insulation colour.  The ultimate advice to exchange grey management wire is stipulated in NEMA-100-2021, Wire Insultation Colours for Lighting Programs and is represented within the picture beneath.  The picture beneath offers the appropriate colours as outlined by the CIELAB colour house for compliance with NEMA-100.

Going ahead, lighting management methods ought to embrace violet and pink wire of their low-voltage management circuits as an alternative of the normal violet and grey, prompting a not insignificant change to design documentation and manufacturing procedures.

NEMA is a commerce affiliation serving each the enterprise and scientific communities.  One in every of its primary contributions to {the electrical} and electronics industries is the event of requirements to be used by firms within the design and manufacture of their merchandise.  NEMA is an ANSI-accredited Requirements Creating Group (SDO), and serves because the secretariat for 5 ANSI Lighting Committees, one in all which is the C137 Lighting Programs Committee.  This committee is tasked, as its identify implies, with improvement of requirements for each indoor and out of doors lighting methods.  The C137 Committee has lately launched two requirements that present perception into the route the lighting trade is taking.

  • ANSI C137.5-2021, American Nationwide Customary for Lighting Programs – Power Reporting Necessities for Lighting Gadgets, addresses vitality measurement for lighting methods and gadgets in recognition that entry to real-time vitality consumption information is turning into more and more related to customers.
  • ANSI C137.6-2020, American Nationwide Customary for Lighting Programs – Information Tagging Vocabulary (Semantic Mannequin Components) for Interoperability, offers a vocabulary for widespread information tags utilized in lighting methods.  This normal was developed in response to the necessity for widespread phrases to facilitate information trade for management and evaluation.

NEMA’s Lighting Programs Division can be the secretariat for the C136 Requirements for Roadway and Space Lighting Committee.  The requirements developed by this committee are extra targeted on tools necessities vs. the extra system-level requirements of C137.  Just lately printed C136 requirements additionally replicate modifications within the lighting trade.

  • ANSI C136.50-2021 – American Nationwide Customary for Roadway and Space Lighting Tools – Power Measurement for a Community Lighting Management (NLC) Machine with a Locking-Kind Receptacle, addresses vitality consumption measurement necessities for what are generally known as “twist-lock” lighting controllers sometimes mounted atop lighting poles.  
  • ANSI C136.52-2021, American Nationwide Customary for Roadway and Space Lighting Tools – Metering Efficiency Necessities for LED Drivers with Integral Power Measurement, offers efficiency necessities for LED drivers utilized in out of doors functions for vitality consumption metering.

The Illuminating Engineering Society (IES) can be concerned within the improvement of ANSI-accredited requirements for the lighting trade.  Simply over a 12 months in the past, the IES launched its Lighting Library, a web-based compendium of its requirements.   IES requirements are typically targeted on really useful practices for lighting designers, take a look at procedures for lighting merchandise, and different matters associated to lighting science and software.

And final, whereas readers are nearly actually conversant in IEEE, they may not know that an working unit, the Institute of Electrical and Electronics Engineers Requirements Affiliation (IEEE SA), is the IEEE inside worldwide physique tasked with improvement of world IEEE requirements.  In contrast to ANSI, the IEEE SA isn’t approved by anybody authorities however moderately, capabilities like different worldwide our bodies resembling ISO and IEC.
