A recent experiment investigated the fundamental electrical parameters associated with an automatic lamp dimming system, conducted in a controlled environment with specialized equipment, including various power supplies, LEDs, and measurement tools. Results indicated that power output was influenced by dimming percentage, revealing a consistent relationship between luminance and electrical parameters, such as voltage and current. The study also introduced a dimming algorithm that adjusted brightness in 5% increments, using statistical analyses to optimize measurements despite some inconsistencies. Additionally, the system’s real-world performance was evaluated, demonstrating a significant 75.65% reduction in energy consumption compared to standard lamps under identical conditions. The findings underscore the potential benefits of automatic dimming systems in reducing electricity expenses in naturally lit environments, with validated results contributing to their reliability and effectiveness for future applications.
