A light-emitting apparatus includes a light-emitting diode that functions as a light source, and a teardrop-shaped translucent member formed of a translucent material. The teardrop-shaped translucent member includes a bottom portion via which the light emitted from the light-emitting diode is input, a lateral portion configured to provide total internal reflection of the light input via the bottom portion, and a top portion configured to focus the light subjected to total internal reflection by the lateral portion so as to form an image.
