Abstract:
A light source driving apparatus includes: a switching driver which performs switched-mode power conversion and outputs a first current toward a light source, to control quantity of light emitted from the light source; and a current bypasser which bypasses at least a part of the first current so that a second current branched from the first current flows in the light source.
