Abstract
A photoconversion device includes a first wavelength converter and a long-pass filter. The first wavelength converter receives excitation light from an output portion and emits fluorescence having a longer wavelength than the excitation light. The long-pass filter transmits the fluorescence emitted by the first wavelength converter and reflects the excitation light transmitted through or reflected from the first wavelength converter to enter the first wavelength converter.
