A light system includes a light source unit including a laser light source, and a photoelectric transducer having the ability to generate photovoltaic power. The photoelectric transducer generates the photovoltaic power when receiving power feed light emerging from the light source unit. The light source unit may cause the power feed light and light for lighting for lighting up a target space to emerge from the light source unit itself. The power feed light is to be incident on the photoelectric transducer.

Light system

A first light source device emits first light having a first wavelength. A second light source device emits second light having a second wavelength longer than the first wavelength. A splitting unit is configured to split the first light into third light having a third wavelength same as the first wavelength and fourth light having a fourth wavelength same as the first wavelength. A wavelength converter is configured to be excited by the third light to emit fifth light having a luminescence peak at a fifth wavelength between the third wavelength and the second wavelength. A combining optical system is configured to combine the second light, the fourth light, and the fifth light together. A control device is configured to control a light output of the second light source device and a split ratio between the third light and the fourth light in the splitting unit.

Light source system

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.

Lighting system

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.

Construction component, light radiating system, and illumination system

An optical fiber module includes an optical fiber containing a glass component, and a ferrule which is tubular in shape and covers an outer circumferential surface in an end portion of the optical fiber. The outer circumferential surface of the optical fiber and an inner circumferential surface of the ferrule are bonded by a silicone resin containing siloxane bonds at cross-linking points.

Optical fiber module, lighting device, and method of manufacturing optical fiber module

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.

Light source device, light source driver, and lighting system

In a spinning forming method, a plate including a peripheral portion at which a ring-shaped projection is provided is used, the projection projecting in a thickness direction of the plate. Further, while rotating the plate, a transform target portion of the plate is locally heated, and a processing tool is pressed against the transform target portion to transform the plate. According to this configuration, a heat capacity of the peripheral portion of the plate can be increased. With this, when heating the vicinity of the peripheral portion of the plate, the peripheral portion can be prevented from becoming high in temperature. As a result, deformation of the peripheral portion of the plate can be suppressed.

Spinning forming method

A method of manufacturing a preliminary formed body includes an ironing step and a thickening step. In the ironing step, a predetermined range of a plate is formed into a tapered shape in such a manner that while rotating the plate, a transform target portion of the plate is locally heated by induction heating, and a processing tool is pressed against the transform target portion. In the thickening step, a peripheral portion that is a distal end of the tapered shape of the plate is expanded inward in such a manner that while rotating the plate, the peripheral portion is locally heated, and a forming roller is pressed against the peripheral portion to push the peripheral portion in a direction orthogonal to a thickness direction of the peripheral portion.

Method of manufacturing preliminary formed body and axisymmetrical component

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.

Light source device

A spinning forming method includes a first forming step and a second forming step, in each of which a plate fixed to a main shaft is formed while being rotated. In the first forming step, a processing tool is brought into contact with a first main surface of the plate to form a first level-changing portion extending from the first main surface toward a second main surface. In the second forming step, the processing tool is brought into contact with the second main surface at an outer peripheral side of the first level-changing portion to form a second level-changing portion extending in an opposite direction to the first level-changing portion.

Spinning forming method and spinning forming apparatus

First, an annular first layer including a plurality of beads and having a width that is not less than twice a width of the bead is formed by laser metal deposition on a peripheral surface of a base metal, the peripheral surface facing outward or inward in a radial direction. Next, a plurality of annular height raising layers each including a plurality of beads are stacked on the first layer by the laser metal deposition. According to this configuration, an axisymmetric body including a flange portion having a relatively wide width can be manufactured while making a heat affected zone in the base metal extremely small.

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.
