Abstract: A lighting apparatus includes a holder that holds an optical fiber, a wavelength converter that wavelength-converts laser light emitted from the optical fiber, and a case that is made of metal, holds the wavelength converter, and houses the holder. The holder includes a main body having a lead end face from which the laser light is emitted, and a flange projecting from an outer circumferential face of a base end of the main body. The case has a through hole penetrating from one end face to another end face, and the wavelength converter is attached to the case to be coaxial with the through hole. The through hole houses the main body, and has an abutting face which the lead end face of the main body abuts. The flange is secured to the case in a state where the lead end face of the main body abuts the abutting face.

Abstract: The light emitting module includes a light source unit and a base plate where the light source unit is detachably mounted. The light source unit has an installation mechanism for installation to the base plate, and the base plate has an installation mechanism counterpart engaged with the installation mechanism. In addition, the light emitting module has a hook mechanism that catches the light source unit and the base plate when the installation mechanism and the installation mechanism counterpart are not engaged with each other. The hook mechanism is contained within a thickness of the light source unit when the light source unit is mounted to the base plate. In this configuration, it is possible to prevent the light source unit from dropping from the base plate using the hook mechanism even when engagement between the installation mechanism and the installation mechanism counterpart is released.

Abstract: 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.
