Abstract
A photoconversion device includes a holder, a wavelength converter, and an optical element. The holder holds an output portion that outputs excitation light. The wavelength converter includes an incident surface section including a protruding surface to receive the excitation light from the output portion and emits fluorescence in response to the excitation light incident on the incident surface section. The optical element includes a focal point surrounded by the incident surface to direct the fluorescence emitted by the wavelength converter in a predetermined direction.
