Abstract

A light fitting comprising: a housing (2) defining an aperture (3) and a cavity; a reflector (10) at least partially located within the cavity of the housing; and a light source (4) including one or more light emitting diodes arranged with respect to the housing and reflector such that a substantial part of the light emitted by the one or more light emitting diodes passes indirectly through the aperture (3) by passing through at least part of the cavity and reflecting from the reflector through the aperture.
