Abstract
A wavelength. conversion device includes a motor having a rotation axis and a hollow space, a wavelength converter converting incident first light in a first wavelength band to second light in a second wavelength band that is different from the first wavelength band, and a coupling member thermally coupled to the wavelength converter. At least a part of the coupling member is arranged in the hollow space. The motor changes a position of incidence of the first light on the wavelength converter relatively with respect to the wavelength converter.
