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: In a projection system, a light source unit emits a first visible light beam, a second visible light beam having a longer wavelength than the first visible light beam, and a near infrared light beam. A spatial light modulation unit subjects the first visible light beam, the second visible light beam, and the near infrared light beam, all emitted from the light source unit, to spatial light modulation to produce a first image light beam, a second image light beam, and a third image light beam, respectively. A controller makes a projection optical system not only selectively project any one of a plurality of image light beams, including the first image light beam, the second image light beam, and the third image light beam, but also selectively project any two or more of the plurality of image light beams, by controlling the spatial light modulation unit in two different manners.

Abstract: A light source device and a method of manufacturing a light source device are provided. The light source device includes a base. A light-emitter is above the base. A cap is joined to the base to cover the light-emitter. The cap includes an opening in a position corresponding to the light-emitter. A first light guide is in communication with the opening for guiding, to outside of the cap, light emitted by the light-emitter. A first ferrule is provided around the first light guide. The first ferrule is joined to an edge of the opening in a state in which the first ferrule is in the opening.

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 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 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 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.
