[Spatial distribution of light intensity under a phototherapy unit]

The distribution of energy under a phototherapy unit containing 8 tubes is uneven; a significant maximum in energy is observed at the centre of the unit. It is therefore desirable to situate the baby at this point of maximum energy. The presence of lateral reflectors however (either metal foil or white sheets), result in not only an increase in energy, but also a more even energy distribution. Therefore the necessity of placing the baby at a special position is no longer required.
