摘要： 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.

摘要： An illumination apparatus includes: a housing which is tubular and includes a first end surface through which laser light enters and a second end surface having an opening through which the laser light exits; a light emitter which is in contact with the second end surface of the housing to block the opening, and emits light having a wavelength different from a wavelength of the laser light when illuminated with the laser light passing through the opening; and a condenser lens which is disposed in an internal space of the housing and condenses the laser light onto the light emitter, thereby forming a spot. When viewed along an optical axis of the laser light in the internal space, the opening has a shape larger than the spot of the laser light on the light emitter and smaller than a circumference of the condenser lens.
