  • Publication number: 20160367124
    Abstract: A light source apparatus includes at least one light-emitter, a driving circuit, an input unit, a temperature control circuit, and an effective light power setting circuit. The driving circuit allows the light-emitter to emit light by applying a driving waveform to the light-emitter.
