Abstract: A light emitting apparatus is provided. The light emitting apparatus includes a light source which emits laser light. A first light guide, which is flexible, extends from the light source for guiding the laser light emitted by the light source. A second light guide, which has a fixed shape, is connected to the first light guide for guiding the laser light emitted by the light source. A body holds the second light guide and sends out, to an outside of the body, light based on the laser light guided by the first light guide and the second light guide.

Abstract: A lighting system includes a light source unit and a light-distributing member. The light source unit includes a laser light source. The light-distributing member has the function of reflecting incident light that has been emitted as a beam of light from the light source unit toward a target space. The light-distributing member transforms the incident light into lighting light having a different light distribution property from the incident light and distributes the lighting light over the target space.

Abstract: A light source device according to an embodiment is used with a light guide member and a wavelength converting member, and includes a light-emitting element, a light sensor, and a driving unit. The light-emitting element radiates a light beam to be incident on a first end of the light guide member by being supplied with a drive current. The light sensor detects signal light, which has been incident on a second end of the light guide member and transmitted to the first end. The driving unit supplies the drive current to the light-emitting element and controls the drive current based on a result of detection of the signal light.

Abstract: A light source device is provided. The light source device includes: a ferrule which holds an optical fiber; a light-emitting element which emits laser light; and a casing which houses the ferrule and the light-emitting element such that the laser light enters the optical fiber. The casing includes a through hole from a first end face to a second end face. The through hole includes a diameter which decreases in a stepwise manner from the first end face toward the second end face. The ferrule is fitted to a small bore portion of the through hole, which is smallest in diameter. The light-emitting element is fitted to a large bore portion of the through hole, which is larger in diameter than the small bore portion.

Abstract: A light source apparatus and a projection display apparatus according to the present disclosure include: a laser light source; and a multiplexing reflection mirror having a first surface on which a partial reflection coating having a predetermined reflectance is formed, and a second surface on which a total reflection coating is formed, the first surface and the second surface being opposite to each other and formed in a parallel flat shape. The multiplexing reflection mirror is disposed so as to incline toward an optical path of an emission light from the laser light source such that the emission light is incident from first surface.

Abstract: A construction component forms at least a part of a structure that faces a target space. The construction component has a first function, a second function, and a third function. The first function is a function of emitting illumination light toward the target space. The second function is a function of allowing incident light to enter the construction component. The incident light is emitted from a light source disposed out of a projection area, viewed from the target space, of the construction component and is incident on the construction component via a light transmission member. The third function is a function of converting the incident light into the illumination light.

Abstract: A luminaire including a wavelength converter and a method of manufacturing the luminaire are provided. The wavelength converter radiates, based on a laser light beam, a light beam having a wavelength different from the laser light beam. The method of measuring the luminaire includes measuring wavelengths of laser light beams oscillated by a plurality of laser elements to identify main wavelengths of the plurality of laser elements, storing association information between main wavelength information items indicating the main wavelengths identified and element information items identifying the plurality of laser elements corresponding to the main wavelengths identified, selecting a combination of laser elements having a composite wavelength falling within a predetermined range, from the plurality of laser elements, based on the association information, and arranging optical paths to irradiate a same area of the wavelength converter with the laser light beams of the combination of laser elements selected.
