Abstract: A lighting device that is capable of illuminating in all directions includes: a case that includes a plurality of wall portions each including a face in a polygonal shape; a plurality of light-emitting elements that are provided in the plurality of wall portions and emit light toward outside of the lighting device; and a controller that controls the plurality of light-emitting elements separately. The case is of an outer shape that is spherical or polyhedral. The case includes bent portions that are bent in the outer shape of the case. The bent portions constitute at least three sides of the outer shape of the case.

Abstract: A wavelength conversion device includes: a substrate; and a phosphor layer on the substrate. The phosphor layer includes: a base material; and a first phosphor and a second phosphor each of which emits fluorescent light when excited by excitation light. Where chromaticity coordinates of the fluorescent light emitted by the first phosphor and chromaticity coordinates of the fluorescent light emitted by the second phosphor are (x1, y1) and (x2, y2), respectively, −0.02≤x1−x2≤0.02 and −0.02≤y1−y2≤0.02 are satisfied. A peak wavelength of an excitation spectrum of the first phosphor is different from a peak wavelength of an excitation spectrum of the second phosphor.

Abstract: A wavelength conversion device is provided. The wavelength conversion device includes a light-transmissive substrate that includes an incidence surface and an emission surface opposite the incidence surface. The light-transmissive substrate is configured to receive, by the incidence surface, excitation light and emit, from the emission surface, the excitation light. A phosphor layer is configured to emit fluorescent light when excited by the excitation light emitted from the emission surface. The phosphor layer includes a first phosphor layer and a second phosphor layer. The first phosphor layer includes first phosphor particles. The second phosphor layer includes second phosphor particles configured to emit fluorescent light including a peak wavelength longer than a peak wavelength of fluorescent light emitted by the first phosphor particles. The first phosphor layer includes a refractive index different from a refractive index of the second phosphor layer.

Abstract: A wavelength conversion device is provided that includes: light-transmissive substrate that includes an incidence surface and an emission surface opposite the incidence surface, and emits, from the emission surface, laser light that enters the incidence surface; a phosphor layer that emits fluorescent light when excited by the laser light emitted from the emission surface; and a light diffuser layer between the emission surface and the phosphor layer. The light diffuser layer is, when viewed in a direction perpendicular to the emission surface, disposed only in a portion of a region in which the phosphor layer is disposed.
