Irradiance Non-Uniformity in LED Light Simulators

Photovoltaic (PV) cells are a technology of choice for providing power to self-sufficient Internet Things (IoT) devices. These devices’ declining demands can now be met even in indoor environments with low light intensity. Correspondingly, simulation systems need cover wide spectrum irradiance intensity emulate PV cell’s working conditions while meeting cost targets. In this paper, we propose method calculating the distribution given number and position LED sources meet uniformity requirements LED-based simulators. addition, establish design guidelines minimizing non-uniformity under specific constraints utilize function evaluate degree determine optimal distance from illuminated surface. We demonstrate that small low-cost sources, high levels achieved bounded non-uniformities. The presented serve as resource designing tailored, simulators users’ area/intensity/uniformity specifications.
