Abstract
An illumination apparatus includes a light-emitting element, a first lens, and a second lens. A first incident surface of the first lens faces the light-emitting element, and guides a light beam from the light-emitting element to a radiation port. A second incident surface of the first lens guides a light beam not passing through the first incident surface to a direction toward the outer periphery of the first lens. A first reflection surface of the first lens reflects a light beam from the second incident surface to guide the light beam to the radiation port.
Claims14
An illumination apparatus, comprising:
- a light-emitting element;
- a first lens that is placed facing the light-emitting element and that has a radiation port from which a light beam is emitted;
- and
- a second lens that is placed facing the radiation port, wherein
- the first lens further has
- a first incident surface that faces the light-emitting element and that guides a light beam from the light-emitting element to the radiation port,
- a second incident surface that guides a light beam not passing through the first incident surface to a direction toward the outer periphery of the first lens,
- a first reflection surface that reflects a light beam from the second incident surface to guide the light beam to the radiation port, and
- a second reflection surface that reflects a light beam passing through the first incident surface and then deviating from a direction toward the radiation port, and a light beam reflected on the first reflection surface and then deviating from the direction toward the radiation portion, to guide these light beams to the radiation port.
