摘要：
A light source apparatus includes a plurality of light source parts, a power supply part, a current selection part and a current control part. The plurality of the light source parts are connected in parallel and the power supply part provides power to a first terminal of each of the light source parts. The current selection part selects the current level of one of the light source parts as a reference current level. The current control part adjusts the levels of the currents flowing through the light source parts to be substantially equal to the reference current level. Selection of the light source part that provides the reference current level is dynamically changed.
