Abstract: A light guide includes an incident surface, an emitting surface, a reflecting surface, and a light guide section. The incident surface receives light from a plurality of light-emitting elements arranged at least in a first direction. The emitting surface outputs incident light from the incident surface. The reflecting surface includes a plurality of lenses having optical power in the first direction and a second direction different from the first direction and is provided to be opposed to the incident surface. The light guide section includes a surface including the incident surface, the emitting surface, and the reflecting surface, and causes the light that has entered from the incident surface to be reflected by the plurality of lenses of the reflecting surface to guide the light to the emitting surface.

Abstract: A light irradiation apparatus capable of irradiating, while a component having a first side is held on the first side by a holding body of a component mounting apparatus, light onto a reflective plate to irradiate reflected light from the reflective plate from the first side of the component, the light irradiation apparatus including: a plurality of first light-emitting devices; a supporting body configured to support the plurality of first light-emitting devices such that optical-axis directions of the plurality of first light-emitting devices match; and a light guide body configured to guide light emitted from the plurality of first light-emitting devices to the reflective plate so that the reflected light is detected by a detector from a second side of the component on the other side of the first side.

Abstract: An illumination apparatus includes a light source section, an irradiation section, and a selection section. The light source section includes a light source configured to emit first-wavelength light having a first wavelength in order for an imaging apparatus to image a subject. The irradiation section is configured to convert the first-wavelength light from the light source into second-wavelength light having a second wavelength different from the first wavelength and to radiate the second-wavelength light to the subject. The selection section is configured to select the second-wavelength light as light to enter the imaging apparatus such that an image of the subject is captured using the second-wavelength light radiated to the subject.

Abstract: A light guide including: a body light guide portion including an incident end that light from a light source enters; and a branch light guide portion including a first light guide portion and a second light guide portion that each include an emission end that a light flux exits and are branched from the body light guide portion, the branch light guide portion being configured to cause, such that a first light flux emitted from the first light guide portion directly heads toward an irradiation object and a second light flux emitted from the second light guide portion heads toward the irradiation object via a reflection portion and joins the first light flux, the first light flux and the second light flux to be emitted from the emission ends.
