ABSTRACT:
A direct-indirect luminaire is provided with a direct light control structure between the luminaire's light source and the down light openings in the luminaire's housing. The down light control structure has an interior light capture which extends to meet the light source and which is shaped to substantially conform to the shape of a capturable surface of the light source. The down light control structure captures and directs substantially all of the light emitted from the captured portion of the light source through the housing's down light opening to provide improved control over the down light component of the luminaire.
