摘要： A luminaire includes an excitation light source which emits excitation light. A first fluorescent plate includes a first principle surface disposed across the optical axis of the excitation light. A first phosphor layer is arranged discretely along the first principle surface. A second fluorescent plate is arranged at the downstream side of the excitation light with respect to the first fluorescent plate. The second fluorescent plate includes a second principle surface disposed across the optical axis. A second phosphor layer is arranged discretely along the second principle surface. The second phosphor layer has a wavelength conversion characteristic different from a wavelength conversion characteristic of the first phosphor layer. A support supports the first fluorescent plate and the second fluorescent plate such that at least one of relative positions and rotations of the first fluorescent plate and the second fluorescent plate are adjustable.

摘要： 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.
