| 摘要 |
The present disclosure provides an artificial lighting device (100) that utilises at least one light source (150) disposed in an optical cavity (105) defined by an internal surface of a hollow structural housing. A first opaque portion (140) of the housing is adapted to provide a reflector in the interior of the housing, such that light incident on that first opaque portion (140) from the light source (150) in the cavity (105) in the interior of the housing is reflected towards the cavity (105). A second opaque portion (120) of the housing has a plurality of apertures between the interior and exterior of the housing. Thus, light from the light source (150) is reflected within the cavity (105) by at least the first opaque portion (140) of the housing and is able to be transmitted from the cavity (105), through the plurality of apertures, to the exterior of the housing. The lighting device (100) also includes a lens unit (110) that is aligned with the plurality of apertures. |
