This research focuses on the improvement of a neonate heliotherapy device light source by replacing the conventional fluorescent light with Blue Light Emitting Diodes (BLED). The improved light source achieved low power consumption. Also a microcontroller, ATMEGA 328P was used to regulate the radiation dose in the device making it safe for the treatment of jaundice for newborn babies. The novelty of this work is in the use of a monochromatic light source which offers a wide range of advantages over the fluorescent light-source technology. A Junction Field Effect Transistor was implemented to achieve a high transconductance in this device because of its ability to deliver amplified current with the application of low voltage. The improved heliotherapy device was able to reduce the bilirubin level of a baby with Hyperbilirubinemia from 20 mg per deciliter to 5 mg per deciliter in 48 h.
