Zusammenfassung:	A light emission device (1) includes a light source (3) that emits an excitation light beam (101), a light deflector (140) that deflects the excitation light beam (101), a wavelength converter (160) that receives and converts the excitation light beam (101) deflected by the light deflector (140) to wavelength-converted light of a different wavelength and emits the wavelength-converted light, and a light concentration section (10) that focuses the excitation light beam (101) on the wavelength converter (160). The light concentration section (10) includes a first optical system (11) disposed between the light source (3) and the light deflector (140), and a second optical system (12) disposed between the light deflector (140) and the wavelength converter (160). In the second optical system (12), a focal length of an Ay-axis is shorter than a focal length of an Ax-axis, where the Ax-axis is defined as an axis that has a lowest beam parameter product of the excitation light beam (101), and the Ay-axis is defined as an axis orthogonal to the Ax-axis in a cross section perpendicular to a propagation direction of the excitation light beam (101).
