Motivation

• Provide a plug-and-play, cost-effective and robust solution enabling end-

users to replace interoperable linear modules.

• The interface definition should allow for sufficient options for differentiation at

both connector and LED module level.

• The proposal aligns nicely with the recent Zhaga move towards

interoperability and serviceability of components of LED luminaires.

• Moreover, it supports Zhaga in its mission enabling the lighting industry for

the upcoming service / circular economy.

Included interfaces to achieve long-term end- user field replaceability and interoperability

• Electrical

– Between module and connector: LED+, LED-

• Mechanical

– Contact area (see separate slide on mechanical interface) – Set module dimensions (length, width) – Specific locations and dimensions to attach module to the luminaire

• Thermal

– Modules are typically self-cooling (e.g. no TIM required) – Define worst case luminaire to check thermal interoperability

• Electro-optical

– Set basic light technical properties by defining Flux @ I max

Electro-optical interface

• Simplified category definition by defining Flux @ I max
• OEMs can design-in drivers at < Imax current levels.
• Fix Lm-ratios for other CCT/CRI levels
• Driver voltage is used to correct for increased LED efficacies.
