    Abstract: A lighting apparatus comprises a housing and a first reflector. The first reflector is mounted beneath the light source and includes a plurality of segmented reflectors, each having at its top, a installation hole and at its bottom, an opening wider than the installation hole. A second reflector is positioned beneath the first reflector. The height of the second reflector causes a first light shielding angle defined by a straight line passing through the installation hole and the bottom edge of the corresponding segmented reflector to be larger than a second light shielding angle defined by a straight line passing through the bottom edge of the segmented reflector and the bottom edge of the second reflector.

    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.
