Transitioning from Halogen to LED: Neonatal Warmer Power Board Redesign

Neonatal infant warmers play a crucial role in maintaining newborns' body temperatures, particularly by mitigating convective and evaporative heat loss. Traditional warmers based on halogen lights have been increasingly replaced by Light Emitting Diode (LED)-based systems due to their enhanced efficiency and performance characteristics. This paper presents a detailed study on redesigning the power board of neonatal infant warmers to accommodate LED technology. The redesign focuses on adapting the power supply configurations, voltage regulation, and thermal management systems to support the electrical requirements of LEDs. Key improvements include integrating LED drivers, optimizing thermal dissipation mechanisms, and ensuring compliance with safety standards. Performance evaluations demonstrate significant reductions in energy consumption and heat generation, contributing to safer operation. Moreover, the LED-based system offers enhanced reliability and maintenance benefits compared to conventional halogen-based designs. This research aligns with medical technology goals by advancing environmental sustainability and improving neonatal care through innovative lighting solutions.
