  "textContent": "An illumination apparatus includes a light-emitting element, a first lens, and a second lens. The first lens faces the light-emitting element, and has a radiation port from which a light beam is radiated, a first incident surface, a second incident surface, a first reflection surface, and a second reflection surface. The second lens faces the radiation port. The first incident surface faces the light-emitting element, and guides a light beam from the light-emitting element to the radiation port. The second incident surface guides a light beam not passing through the first incident surface to a direction toward the outer periphery of the first lens. The first reflection surface reflects a light beam from the second incident surface to guide the light beam to the radiation port. The second reflection surface reflects a light beam passing through the first incident surface and then deviating from the direction toward the radiation port, and a light beam reflected on the first reflection surface and then deviating from a direction toward the radiation port, to guide these light beams to the radiation port.",
