Solution Overview

Problem

Existing operating devices for lamps with emergency power supplies face challenges in managing thermal stress, as both electronic components and batteries are sensitive to temperature extremes, leading to performance degradation and requiring separate, complex installations.

Innovation Solution

Combining electronic components and emergency power supply means within a single housing with a thermal barrier, utilizing a thermally separated design where intermediate walls and air circulation paths prevent excessive heat transfer between the two areas, and using printed circuit boards for electrical connections to maintain thermal separation.
