Abstract:
1. A lighting apparatus comprising: a plurality of light-emitting devices configured to emit light to an outside of the lighting apparatus; a substrate comprising a light projection side, wherein the light-emitting devices are located on the light projection side; a blind member which encloses an outermost periphery of the light-emitting devices and opens radially outward from the light projection side; and a reflector formed with a plurality of reflective surfaces corresponding to the light-emitting devices, individually, in such a manner that a shielding angle, at which a light emitted directly from one of the light-emitting devices which is located on the outermost periphery is intercepted by one of the reflective surfaces corresponding to the light-emitting device located on the outermost periphery, is greater than shielding angles at which light emitted directly from the light-emitting devices located inside the outermost light-emitting device is intercepted by the reflective surfaces corresponding to the inside light emitting devices, wherein the reflective surface corresponding to the outermost light-emitting device and the blind member are formed so that the light emitted directly from the light-emitting device located on the outermost periphery within a range farther from an observation point, which is distant at right angles to directions of emission of lights directly from the light-emitting devices, than a center of the light-emitting devices is intercepted by the reflective surface corresponding to the outermost light-emitting device when the light emitted from the light-emitting device located on an inside periphery within the range farther from the observation point than the center of the light-emitting devices is intercepted by the blind member.
