Wecallourapproach”CircularityLighting”(Figure 4),aconceptthatensures LEDluminairesandlightingmanagement systemsarerepairable,upgradable,replaceable,anddurable.

Toachievethis,interfacestandardization iskey.Bydeﬁningmodular,widelyrecognizedcomponentinterfaces,Zhaga Bookscreateaseamless,interoperable ecosystemwhereluminaires,LEDmodules,controlgear,andsensorscanbe easilyintegrated,maintained,andupgradedovertime.Thisapproachhelps ‘closetheloop’inthelightingindustry, supportingasustainable,service-based businessmodel.

Comparisonwith ExistingRepairability ScoringSystems

Repairabilityscoringsystemsalreadyexist,mostnotablytheiFixit [6] repairability indexinFrance,whichhasbeenwidely adoptedforconsumerelectronicssuchas smartphones,laptops,andotherportable devices.iFixit’s [6] approachevaluates factorslikeeaseofdisassembly,availabilityofspareparts,andthequalityofrepair documentation—helpingconsumersmake informeddecisionsaboutthelongevityand sustainabilityoftheirdevices.

However,theseestablishedframeworks havenotbeenspeciﬁcallytailoredtothe uniquechallengesofthelightingindustry. Luminairesdiffersigniﬁcantlyfromconsumerelectronics,especiallywhenconsideringfactorssuchastheirspecialized lightingcomponents,andthevariedrepair practicesrequiredforapplicationsranging fromdesklightingtostreetlighting.

TheBRLRepairabilitystandardfillsthisgap bydevelopingadedicatedmethodology forassessingtherepairabilityofluminaires. Byincorporatingindustry-specificcriteria— suchasaccessibilityofcomponents,the availabilityofparts,anddetailedsoftware/firmwareconsiderations—theBRL approachprovidesamoreaccurateand actionableevaluationformanufacturers, municipalities,andbuyersinthelighting sector.

HistoricalContextand Evolutionof RepairabilityinLighting

Repairabilityhasnotalwaysbeenafocalpointinlightingdesign.Traditionally, lightingproducts,especiallyincandescent andfluorescentlamps,weredesignedfor easyreplacement.However,thetransitiontoLEDtechnologybroughtsignificant changes.WhileLEDsoffersuperiorenergyefficiencyandlongevity,theyareoften integratedintofixturesinwaysthatmake repairdifficultorimpossible.Manyearly LEDluminairesweresealedunits,withno practicalwaytoreplacefaultycomponents withoutreplacingtheentirefixture.

ForLEDmodules,achievinginteroperability presentsgreaterchallenges.WhileZhaga [5] standardsoffernumerouspossibilities, thephotometricinterface,inparticular, canbecomplex.Ensuringconsistentlight distributionandqualityacrossdifferent LEDmodulereplacementsrequiresprecise speciﬁcationsandadherencetostandards.

3.Interfaces(Software&Firmware)

Interfacesplayacriticalroleinmodern luminaires.Themethodologyevaluates:

• Useofopenvs.proprietarysoftware.

• Programmingaccessibility(usinggeneralpurposetoolsvs.manufacturer-speciﬁc solutions).

ZhagaandDALI [5] organizationsactively contributetoopenstandards,ensuring futureinteroperabilityandeaseofmaintenance.
