Abstract:
A lighting apparatus is provided with a plurality of light-emitting devices, a substrate, a blind member, and a reflector. The reflector is formed with a plurality of reflective surfaces corresponding to the light-emitting devices, individually. The shielding angle at which light emitted from that one of the light-emitting devices which is located on the outermost periphery is intercepted by the reflective surface corresponding to the outermost light-emitting device is greater than shielding angles at which light emitted 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.
