Abstract: A lighting apparatus includes a holder that holds an optical fiber, a wavelength converter that wavelength-converts laser light emitted from the optical fiber, and a case that is made of metal, holds the wavelength converter, and houses the holder. The holder includes a main body having a lead end face from which the laser light is emitted, and a flange projecting from an outer circumferential face of a base end of the main body. The case has a through hole penetrating from one end face to another end face, and the wavelength converter is attached to the case to be coaxial with the through hole. The through hole houses the main body, and has an abutting face which the lead end face of the main body abuts. The flange is secured to the case in a state where the lead end face of the main body abuts the abutting face.

Abstract: A particle sensor is provided. The particle sensor includes a light projector that projects light to a detection area. A light receiver receives scattered light. The scattered light is light from the light projector that has been scattered by particles in the detection area. A first reflector reflects the scattered light to the light receiver. A light attenuator attenuates stray light that exits the first reflector. The first reflector includes a first aperture that introduces the light from the light projector into an interior of the first reflector and a second aperture that exits the stray light from the first reflector. The light attenuator includes a third aperture through which the stray light that exits the first reflector passes. An aperture area of the third aperture is smaller than an aperture area of the second aperture.
