The present invention provides an improved wall-mounted lighting unit for creating a visual environment which is conducive to general care lighting and which requires both good vertical lighting and good brightness control. The lighting unit utilizes a microbase prism design in a refractor which preferably forms a portion of the bottom surface of the housing to provide good horizontal illumination and internal linear optics for good vertical illumination of the subject as well as providing a high visual comfort index. The lighting unit also has a unique leveling feature which compensates for irregularities in the surface of the wall upon which it is mounted. Backlighting can be provided by the lighting unit using a series of apertures which increase the structural integrity of the unit and also simplify its manufacture. |
