英文摘要	A light emission device includes a light source that emits an excitation light beam, a light deflector, a wavelength converter that receives and converts the excitation light beam deflected by the light deflector to wavelength-converted light, and a light concentration section that focuses the excitation light beam on the wavelength converter. The light concentration section includes a first optical system disposed between the light source and the light deflector, and a second optical system disposed between the light deflector and the wavelength converter. In the second optical system, 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, 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.
