Abstract
A light-emitting apparatus includes a first light guide, a converter, a second light guide, and a return. The first light guide includes a first photoreceptor, a second photoreceptor, and a leak. The first light guide guides first light radiated by a radiation apparatus and received by the first photoreceptor and the second photoreceptor. The leak allows second light to be leaked out in a direction crossing a light-guiding direction. The second light is part of the first light. The converter is disposed along the first light guide and converts a wavelength of the second light leaked out of the first light guide. The second light guide does not include the leak and guides third light radiated by the radiation apparatus toward the second photoreceptor. The return returns the third light guided by the second light guide.
