ABSTRACT:
An illuminating apparatus includes a light source (1) and a first reflector (2) arranged for reflecting light emitted by the light source. A three-dimensional attachment is mounted on the first reflector along a direction in which the first reflector reflects. The attachment has a sidewall (6) with a light-transmitting and scattering portion. A panel (7) of the attachment, positioned opposite the first reflector is, opaque. The illuminating apparatus further has a second reflector (3) with a hollowed-segmented sphere shape. The second reflector is positioned between the light source and the opaque panel of the attachment positioned opposite the first reflector. The second reflector (3) is smaller than the first reflector and has a reflecting concave surface facing the light source. The illuminating apparatus is compact, emits diffused light, and displays a bat-wing characteristic light distribution.
