A lighting apparatus including a base is provided. The base includes a through-hole. The through-hole is aligned with an optical path of laser light for receiving and transmitting the laser light. A light emitter which, when irradiated with the laser light transmitted through the through-hole, radiates light by converting a wavelength of the laser light. An attachment component is provided on the base for attachment of the light emitter to the base. The light emitter is removable from the base. A light blocker opens the optical path of the laser light by being contacted by the light emitter when the light emitter is attached to the base, and blocks the optical path of the laser light when the light emitter is removed from the base.

An illumination device includes a light source unit and a light guide plate configured to guide light coming from the light source unit. The light guide plate includes an incidence surface, main emission surfaces from which the light incident on the incidence surface is emitted, and an end emission surface which is opposed to the incidence surface and from which the light is emitted. At least one of the main emission surfaces has a stepped surface which is formed such that the thickness of the light guide plate becomes thinner at a side of the end emission surface than at a side of the incidence surface. The stepped surface is configured to reflect the light in a direction opposite to a light guide direction extending from the incidence surface toward the end emission surface and inclined with respect to the light guide direction.

An illumination apparatus which uses laser light emitted by a light source is provided. The illumination apparatus includes a housing which is tubular, internally includes an optical path for the laser light, and includes a first end surface having an opening through which the laser light passing through the optical path is released. A light emitter is opposed to the opening, receives the laser light released through the opening, converts the laser light into light having a different wavelength of a predetermined color, and emits the light. A cap is removably attached to a first end portion of the housing and through which the light emitted by the light emitter is released. A shutter opens the optical path when the cap is attached to the housing and closes the optical path when the cap is detached from the housing.
