BJB Hintergrund Anschlusselemente für COBs

eCOB - Stands for exchangeable COB´s - Coming soon!

eCOB – The next step toward a sustainable future in lighting.

Our innovative connection system allows for late integration or replacement of COBs during luminaire assembly, offering maximum flexibility in production and maintenance. The modular design with a replaceable inner part for COB and TIM (thermal interface material) allows for easy installation and replacement. It supports COBs in sizes 13.5 x 13.5 mm, 19 x 19 mm, and 20 x 24 mm.

The external connection with plug contacts and retaining springs ensures a secure mechanical and electrical connection. Mounted directly on the heat sink, it guarantees optimum heat dissipation. This system offers a future-proof, flexible, and maintenance-friendly lighting solution.

Quick replacement of the indoor unit – with pre-assembled COB for efficient maintenance, replacement, or late integration into the luminaire.
